Secure and Reliable Networks: Your Frontline Against Cyber Threats

In today’s digital landscape, a stable and secure network is crucial for businesses of all sizes. It forms the foundation of effective cyber threat protection. However, without this foundation, even the most sophisticated cybersecurity tools and systems can fall short. But how can you ensure both security and stability?

An efficient network must be resilient, highly available, robust, scalable, and secure. While there’s no one-size-fits-all solution, implementing best practices tailored to your network environment and your business needs can set you on the right path.  

Let’s explore the key aspects of network security: data network architecture, network segmentation, and network access control.

Data Network Architecture:
Building a Strong Foundation

When defining your network architecture,it is important to consider topology, technology choices, and communication protocols, and ensure they are all tailored to fit your organization’s structure and needs. Whether you’re a small manufacturer, a global enterprise, a university, an ISP, or a data center, understanding the layers of the OSI model is crucial for building a secure network.

At the physical layer (L1), the quality of your infrastructure is paramount. Poor-quality fiber optics, inadequate cabling, or faulty network sockets can undermine network performance. We’ve all seen instances where a network faltered due to damaged cables or dirty connectors. These local problems can escalate to higher levels, potentially disrupting part or all of your network.

Moving up to the data link layer (L2), we encounter the Spanning Tree Protocol (STP). This crucial protocol prevents loops in the network, ensuring only one active path between any devices. However, STP recalculation can affect the entire L2 topology, leading to widespread network outages. To mitigate this risk, it’s essential that all devices within the STP domain support the same STP protocol and, ideally, can create STP trees across individual VLANs. Additionally, accurate configuration of the Root Bridge or the implementation of a Root Guard is highly recommended.

At the network layer (L3), issues from L2 can lead to disruptions. For instance, connecting VLANs between routers within a dynamic routing protocol can introduce problems. To minimize the impact of L2 issues, consider logical or geographical segmentation of your network at the L3 layer.

Maintaining a stable network requires continuous monitoring of all individual elements and performance metrics like Round Trip Time (RTT), Average Response Time (ART), and User Experience Time (UET). Tools like GREYCORTEX Mendel can assist you by tracking these metrics, identifying configuration issues, and reporting anomalies to ensure smooth operations.

Network Segmentation:
Protecting LAN Integrity

Network segmentation plays a crucial role in both the security and performance of your data networks.

From a performance standpoint, it’s advisable to separate individual broadcast domains into network segments using VLANs. This minimizes unnecessary broadcast and ARP queries, leading to a more stable network. Moreover, selecting the optimal STP protocol further reduces the impact on these domains.

From a security perspective, segmenting the network into smaller subnetworks simplifies access control management and eases the inspection of communication between segments. It’s important to monitor whether your current network traffic complies with your security policies.

GREYCORTEX Mendel excels in network security monitoring, providing you with clear insights into your network activities. It also verifies whether current traffic aligns with your security policies and offers a straightforward visualization of the results.

Network Access Control:
Knowing Who’s on Your Network

Effective network access control should be enforced both at the level of network devices and of end users. At the device level, several measures can prevent unauthorized devices from compromising your network:

  • BPDU Guard: This security function detects BPDU (Bridge Protocol Data Unit) packets used for communication and information propagation within the STP. If BPDU packets are detected, it blocks the switch port, preventing an unauthorized “smart” switch from connecting.
  • Port Security: Properly configuring port security involves defining the number of MAC addresses allowed on a single port, thereby limiting the potential use of a connected “rogue” switch. Alternatively, you can allow only a specific MAC address, preventing the connection of any devices other than those that are configuration-approved.
  • 802.1x with EAP (Extensible Authentication Protocol): In dynamic environments where users frequently move and connect from different locations, 802.1x with EAP is recommended. This protocol facilitates user and device authentication, determining network access and dynamically assigning devices to specific VLANs based on organizational departments.
  • Advanced Access Control: For a more detailed approach, additional attributes such as the device’s “health status”, software configuration, or specific settings can be included. This often requires an endpoint agent, which may be standalone or part of an endpoint protection client suit. The agent collects data on the device, such as the OS version, endpoint protection status, installed applications, and registry settings, integrating this information into the access control policy.

GREYCORTEX Mendel offers a clear view of network assets and their interconnections, providing insights beyond what is recorded in asset management systems.

Remote access management

Remote access management is increasingly important as users often work beyond the secure boundaries of their organization. While traditional VPN access still remains popular, it has limitations and often falls short in providing adequate security. To address this, it’s important to monitor several aspects of VPN usage: who is accessing the VPN, which devices or systems they are communicating with, the protocols in use, the services accessed, and the volume of data transferred. GREYCORTEX Mendel can help with carrying out this comprehensive monitoring.

For enhanced security, consider Zero Trust Network Access (ZTNA) solutions, which offer enhanced security by granting access only to specific applications or services, thus improving transparency and control over remote access.

Building a Secure Network Foundation

A high-performing network is the cornerstone of organizational cybersecurity. By leveraging NDR tools like GREYCORTEX Mendel and following best practices, you can ensure superior management and protection of your network infrastructure, strengthening your overall security posture.

Remember, a secure network is not just about having a perimeter defense—it’s about creating a resilient, monitored, and well-managed internal infrastructure that can withstand and respond to various cyber threats. By focusing on these key aspects—architecture, segmentation, and access control—you’ll be well on your way to building a network that’s both secure and reliable.

A quick guide to remote access protocols

Remote access is a business necessity. Around 50% of workers use remote access technologies to work from home or on the move. Many of those workers access remote desktops to recreate workplaces outside the office.

While workers see Office 365 or SalesForce on their displays, a lot happens under the hood. Businesses rely on remote access protocols to connect devices and transfer data. In every case, companies must secure remote access methods while ensuring optimal performance. 

This blog will explore remote access protocols and introduce some popular varieties. We will also list some remote access best practices to help you find the perfect setup.

What are remote access protocols?

Remote access protocols enable connections between remote devices and servers. Protocols set the conditions for transferring data packets, allowing workers to access desktops hosted on centralized data centers. Many protocols also strengthen security by applying encryption to hide traffic from outsiders.

Common types of remote access protocols

Almost every device has an in-built remote access protocol. Windows uses the Remote Desktop Protocol (RDP), while Linux and Macs use the Secure Shell Protocol (SSH).

Protocols have default settings, which often suit user needs. However, there are occasions when customizing remote access protocols is essential. You may also add extra protocols to improve security or ensure compatibility with other systems.

When you deviate from default setups, it’s important to understand how remote access protocols work. Let’s explore the main remote access protocols and how to use them.

10 types of remote access protocols

Remote Desktop Protocol (RDP)

Microsoft created the Remote Desktop Protocol in 2012. RDP uses a server and client setup to organize shared connections between remote devices and central servers. Engineers use RDP to access remote devices securely, and the protocol works with Windows, Linux, Mac OS, and even Android.

RDP uses port forwarding and the TCP/IP transfer protocol to send and receive data over a network channel. This channel carries data about keystrokes, mouse movements, and visual information from remote servers.

With RDP, users don’t need to host apps on their devices. They can access central assets via RDP and work via the remote desktop.

Secure Shell (SSH)

The Secure Shell remote transfer protocol allows remote users to deliver command-line instructions to central devices. The SSH protocol encrypts commands and enables secure file transmission. These features make it a popular protocol for server management.

SSH may also be a good option for secure remote access. The SSH protocol uses public and private keys to authenticate connections. RDP relies on password credentials supplied by remote users, which can be vulnerable to theft or brute force attacks.

Virtual Network Computing (VNC)

Like RDP, VNC users remotely control applications stored on central servers. Unlike RDP, VNC uses the Remote Frame Buffer Protocol (RFB). The screen-sharing protocol allows remote capture of devices, providing greater control compared with RDP.

VNC is popular because it is platform-independent. Many users can connect to a VNC instance, regardless of their operating system. It is a common choice for IT or customer service teams who need secure access to user devices.

Serial Line Internet Protocol (SLIP)

SLIP is one of the oldest remote access technologies, having appeared in the 1980s. First used to connect Unix devices, SLIP is still a popular way to control TCP/IP data transmission.

SLIP creates point-to-point pathways between serial devices. Serial communication is rarely used in remote working as it struggles with audio-visual data flows. However, companies commonly use the technique to control internet-of-things devices due to its low cost and simplicity.

Point-to-point protocol (PPP)

Point-to-point protocols use TCP/IP to create secure connections between remote devices and central servers. Operating at the link layer, PPP is a go-to protocol for Internet Service Providers.

PPP is the foundation of other remote access technologies. For example, Point-to-Point Protocol over Ethernet (PPPoE) allows rapid file transfers over Ethernet connections. PPPoE also enables network monitoring to track user activity.

Virtual Private Networks (VPNs)

Virtual Private Networks use variants of the Point-to-Point Tunneling Protocol (PPTP) to create secure tunnels between clients and servers. Tunneling enhances user privacy by encrypting data and assigning fresh IP addresses.

These features make VPNs some of the most secure remote access solutions. However, VPN protocols are not specialized for remote desktop access. They tend to operate alongside RDP and other remote access technologies.

Remote access VPNs create digital gateways to secure other forms of remote access. That’s especially useful for remote workforces that connect via home offices and unsecured public networks.

VMWare Blast

Blast is VMWare’s virtual display protocol and uses the H.264 video compression standard to transfer video data. Compression makes Blast a good option if companies rely on video conferencing and virtual meetings. It also suits remote desktop access with complex visual demands.

VMWare Blast is platform-neutral, supporting Linux, MacOS, and Windows. It uses the UDP and TCP/IP framework for data transfers, while encryption and authentication functions provide additional security.

Citrix ICA

Citrix ICA is a proprietary remote desktop protocol focused on high-performance desktop access.

The “Independent Computing Architecture” resembles RDP’s client and server architecture. Unlike basic RDP, Citrix ICA optimizes data flows for graphics and audio. This reduces latency and enhances efficiency.

Hypertext Transfer Protocol Secure (HTTPS)

HTTPS is a secure version of the Hypertext Transfer Protocol that transmits most web traffic.

Companies can use it to secure remote access via web applications. For example, HTTPS enables collaboration via Google Docs or access to publishing tools like Canva.

The problem with HTTPS is it only applies to web-based traffic. Users will need additional protocols to secure other forms of traffic.

Apple Remote Desktop (ARD)

Apple’s version of the Remote Desktop Protocol, ARD, allows remote management of MacOS systems. It provides similar services to RDP, including remote admin and file transfers.

IT teams can use ARD to remotely manage software on Apple devices or control many Macs on a company network. ARD also features screen-sharing, file distribution, and software installation to ease the workload for security teams.

ARD is only used with Apple systems. You can use it as part of remote access systems, but other protocols are needed if PCs or other devices are involved.

How should you choose the right remote access protocol for your needs?

Take care when choosing different types of remote access protocol, as the protocol you select influences overall performance.

Remote access solutions should balance criteria and take business needs into account. In some situations, security is critical. In others, speed matters slightly more. Here are some criteria to guide your decision-making:

  • Security. If security is foremost, choose remote access protocols that support strong encryption and authentication systems. A smart remote access setup based on combining VPNs and RDP should protect critical data.

  • Speed and performance. Fast protocols consume minimal bandwidth and generate very little latency—handy if you rely on split-second connectivity. Protocols may also support file compression to reduce transfer volumes, another good way to improve performance.

  • Compatibility. Think about how remote access protocols fit into your network environment. Some RAPs support all operating systems. Others, like RDP or ARD, are less wide-ranging. Check your protocol works with visualization platforms like Citrix (if you use them).

  • Cost. Sourcing a proprietary remote access protocol like VMWare Blast can be expensive, as companies must buy licenses for every user. RDP or other solutions may be better suited to small businesses on cost grounds.

Best practices for using remote access protocols

Challenges remain after choosing remote access protocols. How should you use protocols securely and efficiently to achieve your business goals?

Implementing remote access technologies varies between businesses, but some best practices apply across the board:

  • Use multi-factor authentication (MFA). MFA requires extra user credentials before establishing a remote access session. Most protocols support authentication, which cuts the risk of outsiders gaining control of network devices.

  • Encrypt data securely. Encryption scrambles data packets transported via remote access protocols. Tools like RDP do not provide strong encryption by default. The safest option is applying encryption over the top via VPN protocols.

  • Segment networks for added security. Strengthen protection by isolating remote access servers in secure network segments. Control access to this secure zone and minimize east-west movement if attackers breach remote access defenses.

  • Update software regularly. Remote access protocols can be vectors for exploit attacks. Regular patches and software updates keep network assets current and protected against known vulnerabilities.

  • Monitor remote access. Security teams can monitor data transferred via remote access protocols to detect suspicious activity. Maintain activity logs and schedule regular audits to identify potential problems.

  • Organize user training. Users must know how to use remote desktop protocols securely. Password hygiene, VPNs, patching, and avoiding unsafe public spaces should all appear in training programs.

  • Use load balancing to scale RAP solutions. Scaling remote access protocols can cause performance issues. Load balancing helps you manage bandwidth and avoid network bottlenecks.

Why SWG and CASB solutions are essential for preventing data leakage and cyber threats

Everyday, people fly the friendly internet skies, visiting different websites, and sharing files with each other. They are accessing everything from Gaming to Gambling to General Entertainment websites and sharing files that may contain personal information. Now this is fine if it’s personal activity—but what if you’re part of a professional organization?

If I’m part of the security team at that organization, I’d want some controls to know where you’re going on the internet, how you’re accessing it, and who you’re sharing files with in order to keep you safe from malicious attacks and data leakage.

Is that really necessary?

Let’s take a look at some trends we’ve seen:

Total Blocks in the last 7 days? Over 60k! Where were these users going?

Almost 50% of the blocks were…you guessed it: AI/ML

Organizations are clamping down on Artificial Intelligence usage.

An example of an organization’s blocked content

Top blocked categories

  • 49.1% AI/ML: ChatGPT, Gemini, DALL-E, etc.
  • 8.8% File Storage: Dropbox, Box, WeTransfer, etc. ‍
  • 7.8% Malicious/Suspicious: Block users from being unknowingly exposed to dangerous sites
  • ‍1.9% Software Downloads: Prevent employees from downloading non-approved IT apps

This data begs the question, are employees doing this intentionally?

While it’s hard to know for sure without asking them directly, we can deduce a few things.

  1. AI is on the rise, and every employee is looking to automate their work, the data clearly shows a desire to access these tools. But they’re being blocked because company policies don’t want you uploading proprietary code or sensitive content.
  2. Categories like ‘File Storage’ are blocked to ensure employees can not access their personal cloud storage drives, reducing the risk of data exfiltration. The most common use case we see here is a recently terminated employee trying to take company files with them.
  3. Most of the time employees are completely unaware they are accessing a Malicious site so these blocks are protecting the accidental misstep.

‍

This is why having a reliable and easy to use secure web gateway solution is so important. You need to be able to monitor activity and block access to sites that could be harmful, or non-productive to your organization.

Now what about those company files? I can not tell how many times leaders have said, “No I’m good…we have tight controls and I know we don’t have any publicly exposed files.”

‍

Well, we challenged one of those leaders to run CASB Neural, here are those results:

Out of 84M Files scanned, 2.4% are Publicly exposed. That may not sound like a lot, but it’s over 2M publicly exposed files.

2M Publicly exposed files!

Another way of saying this is that the file is “publicly accessible.” That means while you personally may have never shared this file or folder with anyone outside of your organization, it still has the ability or “sharing permissions” that allow it to be exposed to an external party.

Of those 2M files, over half a million, or 25% of the found public files, fall into either Intellectual Property (IP), Personally Identifiable Information (PII), Protected Health Information (PHI) or Payment Card Industry (PCI).

  • IP 6.2%‍
  • PII 53.2%
  • ‍PHI 5.8%
  • ‍PCI 34.8%

That means either your data, your customers, vendors, or anyones data who you work with could potentially be at risk of being exposed.

What are some examples of the types of files and data we found in these categories?

  1. Publicly exposed data rooms where anyone could download sensitive information (stock purchase agreements, equity, offer letters, etc.) about major startups
  2. PHI documents publicly available because it was the default setting when creating a sharing link
  3. Troves of sensitive files shared publicly, with no possible way to find out, including bank statements, etc.

So what does all this mean?

Most of the time people are not sharing sensitive information, or going to malicious websites on purpose. So having these filters in place is crucial for catching those accidental human errors that will ultimately happen.

Because as the data shows, people are trying to access sites they shouldn’t be, and unknowingly have file sharing permissions that could be huge security risks to your organization.

These solutions keep you productive and safe. So make sure you have a SWG and CASB DLP solution that is fast, reliable and invisible because at the end of the day you want it to work really well and not get in the way.

Server Virtualization: A Game-Changer For Green IT

Server virtualization, a pivotal technology in modern computing, has emerged as a transformative force in Green IT. According to a report from the UN, the IT industry is responsible for approximately 2% of global CO2 emissions. These emissions, primarily stemming from traditional server setups, significantly contribute to environmental challenges worldwide. This highlights the pressing need for sustainable technological solutions: a call for server virtualization. Server virtualization involves partitioning a physical server into multiple virtual machines, each capable of running independent operating systems and applications. This technology enables more efficient use of hardware resources, allowing multiple workloads to coexist on a single physical server.  It significantly reduces energy consumption and ultimately contributes to a more sustainable and eco-conscious approach to technology. This blog post explores how server virtualization has taken center stage in the green IT revolution.

Areas of Green IT

Green IT, or Green Information Technology, is a philosophy that emphasizes the responsible use of technology to minimize its environmental impact. By adopting practices that prioritize energy efficiency, resource conservation, and waste reduction, businesses can play a pivotal role in reducing their ecological footprint. This aligns with global sustainability goals and leads to cost savings and operational efficiency improvements. Energy efficiency in IT infrastructure is crucial. It involves optimizing the consumption of electricity and resources to minimize waste. This is achievable through technologies like virtualization, which allows for consolidating multiple virtual machines onto a single physical server, significantly reducing the overall energy consumption. Moreover, resource conservation involves efficiently utilizing hardware and software to extend their lifespan, minimizing the need for constant upgrades and replacements. Lastly, waste reduction focuses on responsible disposal and recycling practices to minimize electronic waste, creating a cleaner environment.

Significance of Reducing Carbon Emissions in Green IT

Reducing carbon emissions is a pivotal goal in Green IT. The IT sector accounts for significant global carbon emissions, and adopting sustainable practices can lead to substantial reductions. The World Economic Forum’s Global Risks Report consistently lists environmental risks, including carbon overload, among the top global threats. These risks can lead to economic instability, impacting industries, supply chains, and infrastructure. Organizations can make substantial strides towards a greener and more environmentally conscious IT infrastructure by minimizing energy consumption and employing efficient technologies like server virtualization.

Why It’s Good to Invest in Server Virtualization?

Server virtualization offers many benefits, with cost savings and efficiency leading the way.

Cost Savings

Server virtualization is a game-changer when it comes to cost savings. The economic cost of natural disasters related to climate change and carbon overload is substantial. In 2020 alone, these costs reached approximately $268 billion globally. Businesses can significantly reduce their hardware expenses by consolidating multiple virtual machines onto a single physical server. This includes not only the cost of purchasing new servers but also the expenses associated with maintenance, cooling, and physical space requirements.

Energy Savings

Traditional server setups often operate at a fraction of their capacity, leading to inefficient resource allocation and high energy consumption. Server virtualization addresses this issue by enabling businesses to utilize their hardware to its full potential. Virtual machines can dynamically allocate resources based on demand, ensuring optimal performance and reducing waste. A U.S. Environmental Protection Agency (EPA) report found that server virtualization can lead to energy savings of up to 80%. By adopting server virtualization, businesses can reap the benefits of reduced energy consumption, resulting in lower electricity bills and a lighter environmental impact. The reduced hardware footprint also leads to lower cooling costs, further contributing to overall cost savings.

Optimized Resource Allocation

In traditional server setups, it’s common for individual servers to operate at a fraction of their capacity. This inefficiency results in wasted resources and increased energy consumption. Server virtualization addresses this issue by allowing businesses to make the most out of their existing hardware. Virtualization technology enables dynamic resource allocation, meaning that each virtual machine receives precisely the resources it needs to operate efficiently. This eliminates the inefficiencies associated with static resource allocation in traditional setups. Imagine a scenario where every computer in your office adapts its performance to the task at hand. That’s the power of virtualization.

Flexibility and Scalability

Businesses today operate in a dynamic environment. Needs change, and they change fast. Server virtualization provides the agility to adapt quickly to these changes without needing constant hardware upgrades. With virtualization, adding or expanding new applications is as simple as creating a new virtual machine. Investing in additional physical servers is unnecessary, saving both time and money. This flexibility ensures that businesses can respond promptly to evolving demands, staying competitive in today’s fast-paced market. Whether scaling up to meet increased workloads or scaling down during slower periods, virtualization provides the flexibility to adjust resources on the fly. This means businesses can operate efficiently and confidently, knowing their IT infrastructure can meet their changing needs.

How Does Server Virtualization Help to Reduce CO2 Emissions?

Traditional server setups are known for their energy-hungry nature. They involve numerous physical servers, each with its own power requirements and cooling needs. This leads to a significant carbon footprint, as the energy demand for these servers directly contributes to CO2 emissions. A study by the Green Electronics Council paints a compelling picture: firms implementing server virtualization technologies reduced their CO2 emissions by an impressive average of 63% compared to those relying solely on physical servers. Server virtualization does wonders in cutting down energy consumption and CO2 emissions. By allowing multiple virtual machines to operate on a single physical server, the need for multiple servers diminishes. This consolidation leads to a proportional drop in energy usage and CO2 emissions. Moreover, virtualization ensures the smart use of resources. Each virtual machine gets precisely what it needs, precisely when it needs it. This means no more overloading of resources, which is a common inefficiency in traditional server setups. Virtualization platforms also come equipped with power management features. These features dynamically adjust the power consumption of servers based on workload demands. This responsive approach further minimizes energy usage and, in turn, CO2 emissions.

Security and Server Virtualization

Managing security in traditional server setups can be complex and daunting. With multiple physical servers, each requiring individual attention, it’s easy for security gaps to emerge. This complexity can lead to vulnerabilities that malicious actors might exploit. Server virtualization simplifies this process. Businesses can centralize their security measures by consolidating multiple virtual machines onto a single physical server. This means fewer points of entry for potential threats, making monitoring and protecting sensitive data easier. Virtualization platforms come equipped with advanced security features that provide additional protection. These features include secure hypervisors, network segmentation, and secure boot processes, all working together to safeguard critical business data. Virtualization is a powerful tool in fortifying your business against cyber threats. It’s like having a digital security guard who’s always on duty, ensuring your sensitive information stays safe and secure.

Overcoming Challenges in Implementing Server Virtualization

Implementing server virtualization might seem like a big step, and it’s natural to encounter some initial challenges. One common hurdle is the need for staff training. Getting your team up to speed on virtualization technologies may take a bit of time, but the benefits, in the long run, make it well worth the investment. Another consideration is the initial setup cost. While virtualization can lead to significant cost savings over time, acquiring the necessary hardware and software may be an initial investment. However, it’s important to remember that this investment pays off through reduced operational costs and improved efficiency.

Best practices for success

To ensure a successful transition to server virtualization, it’s important to follow some best practices. Learning from the experiences of successful implementations can provide valuable insights. For example, conducting a thorough assessment of your existing IT infrastructure will help plan the virtualization process. This includes evaluating your current hardware, software, and applications to determine compatibility with virtualization technologies. Additionally, considering factors like workload distribution and redundancy planning is crucial for a smooth transition. Implementing a phased approach and conducting thorough testing can help identify and address any potential issues before full-scale implementation.

What is Data Gravity?

If you have ever wondered why data keeps growing and creating big data, there’s a simple and familiar concept behind it. As organizations grow, amassing vast amounts of data, the amount of data in their repository keeps growing, creating an ever-increasing repository of information.

This has to do with how large data attracts more data, applications, and services, increasing in size over time. This phenomenon is called data gravity. Since data gravity is unstoppable, it’s crucial to understand what it is and how to manage and optimize it.

This article explores the concept of data gravity, its effect on organizations, and how to manage it to help you use it to your benefit.

What is the Definition of Data Gravity?

Data gravity is very similar to the physical gravity you are used to. It refers to how big data attracts applications, services, and more data, leading to a snowball effect that quickly increases data size. According to Newton’s law of gravity, the earth attracts other smaller objects to it. Similarly, large data sets attract applications, services, and other data.

Typically, the larger the data set, the more data it attracts, creating a gravitational pull that keeps the data pool close by. This concept applies not only to data in physical proximity to big data but also to the digital realm, that is, data in cloud storage. Examples of data gravity are data warehouses and data lakes.

Consider a business keeping vast volumes of consumer data in a data warehouse. The warehouse expands in complexity and scale as it gathers and analyses increasing volumes of data.

This expansion will draw new uses and services, including customer relationship management (CRM), which is applied for more thorough consumer analysis. This analysis also draws in more data, creating a continuous cycle of data growth over time.

History of Data Gravity

The history of data gravity is relatively close. The term was first introduced in a 2010 blog post by Dave McCory, who was a software engineer at GE Digital. When explaining the concept of data gravity, he used the analogy of physical gravity to explain how large datasets attract IT systems, like how a planet’s gravitational pull attracts objects around it. For example, the moon orbits around the Earth because of gravity. So, similarly, large data, which in this case are applications and services, is like the Earth, attracting the moon.

David McCory also explains in another blog post that data gravity doesn’t only occur naturally; external forces like costs, specialization, and legislative can indirectly influence data gravity. This is called artificial data gravity. He gives an example of AWS S3 that allows unlimited transfer inbound traffic for free. This free unlimited transfer encourages users to gather data, leading to artificial data gravity because it is externally influenced.

Effects of Data Gravity

Data gravity has both positive and negative effects on organizations. Being aware of both sides can help you manage data gravity effectively.

Pros of Data Gravity

The perks include:

  • Centralized Data Management: Data gravity allows organizations to manage data in a centralized data hub, making it easier to manage data across multiple applications and departments.
  • Improved Data Integrity: Centralized data management reduces the risk of data inconsistencies by helping an organization manage its data from one location. Thus, they can monitor data and ensure it is up-to-date and accurate.
  • Better Data Utilization: Big data enables organizations to utilize data effectively. For example, the availability of more data provides more information when performing data analysis.

Cons of Data Gravity

Some major disadvantages are:

  • Scalability Problem: As the size of the data increases, organizations could face scalability issues. Due to the large data size, migrating to better resources or another platform could be uneconomical. This can lead to vendor lock-in as the organization will find it difficult to switch to another platform. Thus, you may become solely dependent on a single provider.
  • Latency: Organizations can face the issue of latency if the applications and services are far from the large data set. If the distance between where data is stored and processed is significant, this distance causes latency, crippling performance. To reduce latency, it’s best to ensure that the data and the gravitating applications and services are close or co-located.
  • Higher Costs: Another problem data gravity poses is the higher cost involved. For example, organizations may need to acquire new storage tools and applications, which could significantly increase data management costs.

Managing Data Gravity

Big data can be overwhelming, so managing data gravity is crucial to ensure that you take advantage of its benefits. Below are some ways to manage your growing data:

  • Cloud-Based Solutions

Opting for cloud storage offers a scalable and flexible solution, enabling organizations to manage large data sets better. Also, cloud services reduce the complexity of data management by making data accessible across different devices and departments. However, storing all data on the cloud is not always possible. So, organizations that need on-premise storage systems should opt for scalable systems that reduce latency. One such solution is hyper-converged systems, which combine storage and networking in one platform, cutting down latency and ensuring effective data management.

  • Data Integration

You can take advantage of data gravity by integrating several data sources into one data hub. Although combining data to form one gigantic data set may seem ineffective, one data source means you have to contend with only one outlet instead of several, making it more organized. Doing so also makes accessing and managing data easier, leading to better performance and fewer errors.

  • Data Governance

Robust data governance policies can also help manage and utilize data gravity. These policies include data standards, access controls, and accountability measures set to ensure the smooth management of big data.

  • Decentralized Architectures

Decentralized architectures like cloud storage can also reduce the risks associated with data gravity. Since these tools don’t need a central physical location, data can be processed closer to where it is generated. As a result, latency can be reduced, and data processing times can be improved.

  • Effective Data Planning

Generally, effective data management can help prevent the risks involved in data gravity. Taking care to consider not just the current needs, but also the future data needs of an organization. Making the right decisions for your data can help manage data gravity.

The Importance of Data Backup in Data Gravity

The more data there is, the higher the risk of corruption and loss. In the event of a data disaster, an organization will lose a large amount of data created by gravity. Thus, it’s crucial to implement robust backup solutions that will protect against data loss during disasters.

However, the biggest problem with data backup in such an environment is not its size. Data attracts new applications or services, which often decentralize data processing, creating new data sources. Therefore, without versatility, data protection can focus only on selected silos, ignoring new data sources. In such a case, we may: 1) consciously not expand the ecosystem with modern tools, 2) agree that some data will not be secured, 3) or implement an additional tool to secure modern workloads, which will only complicate the data management process and may negatively impact their consistency.

No. 4 is, of course, replacing the backup tool with Storware Backup and Recovery, which supports protection for virtual, physical, and cloud data and allows integration with enterprise-class backup devices, expanding their data protection capabilities with new sources.

Also, modern data backup facilitates data mobility by moving data to a different site, reducing the effect of data gravity. Data gravity could easily make data heavy and difficult to move around, but with backup systems, you can reduce the load through regular backup that provides bits of data available for a period. Thus, it’s crucial to prioritize data backup as data pulls more data, application, and services, increasing its bulk.

Conclusion

Like physical gravity, data gravity is inevitable, and unfortunately, if not well managed, it can lead to negative consequences like latency, high cost of operation, and scalability issues. Hence, organizations need to understand how it works, how best to manage it and how to use it to their advantage. Data gravity can lead to better data utilization, centralized data management, and improved data integrity. By following our guide on managing data gravity, you can harness these perks and ensure they work to your advantage.
