Deciphering the Edge: The Convergence of IoT and Edge Computing

The IoT revolution is creating an interconnected world, turning everyday objects into intelligent devices. And the breadth of industries set to benefit from IoT is staggering. In manufacturing, IoT enables real-time monitoring of production lines, improving efficiency and reducing waste. Likewise, the healthcare industry is achieving better care and more accessibility through remote patient monitoring and telemedicine. And agriculture is leveraging IoT for precision farming, allowing for effective resource management and increased crop yield.

However, the growing number of interconnected devices generates a deluge of data that needs to be processed and analyzed efficiently. This is where edge computing comes into play. As these two powerful technologies come together, they open up new opportunities and possibilities for businesses and individuals alike. They promise a more connected, automated, and intelligent future, breaking the boundaries of what we thought was possible. So let’s get into how.

IoT and Edge Computing Explained

The Internet of Things (IoT) refers to the network of physical devices, vehicles, home appliances, and other items embedded with sensors, software, and connectivity, enabling these objects to connect and exchange data.

Edge computing, on the other hand, is a computing paradigm that brings computation and data storage closer to the location where it’s needed, reducing latency and bandwidth use. It’s all about processing data locally to provide quicker, more efficient responses.

While IoT deals with connecting devices and data collection, edge computing focuses on how and where that data is processed. The two concepts, while distinct, are increasingly intertwined as IoT edge computing – a system where data from IoT devices is processed closer to where it is created instead of sending it across long routes to data centers or clouds. This symbiosis improves speed, reduces latency, and enhances data security.

How Can They Work Together? The Benefits of IoT Edge Computing

When coupled, IoT and edge computing form a robust and responsive ecosystem capable of transforming data handling and processing. More specifically, IoT edge computing offers:

  • Reduced Latency: With data processing taking place closer to the source, communication latency between IoT devices and central IT networks is significantly reduced.
  • Faster Response Times: The reduced latency allows for quicker decision-making and responses, enhancing operational efficiency.
  • Improved Network Bandwidth: By minimizing the data sent back to centralized data centers, IoT edge computing optimizes network bandwidth use and reduces potential bottlenecks.
  • Operational Continuity: Edge computing ensures IoT devices can continue functioning even when network connections are lost, guaranteeing uninterrupted operation.
  • Real-Time Data Processing and Decision Making: Local processing enables immediate data aggregation, facilitating faster decision-making with the help of analytics algorithms and machine learning. This leads to more timely insights and improved performance of IoT devices.
  • Increased Data Security and Privacy: Processing data locally at the edge can help enhance security by reducing exposure to potential network vulnerabilities. Additionally, storing less sensitive data on the cloud enhances user privacy.
  • Cost Savings: By reducing the need for continuous high-bandwidth data transmission to the cloud, IoT edge computing can lead to significant cost savings in data transportation and storage.

What is an IoT Edge Device?

An IoT edge device is a piece of hardware that connects the physical world with the digital world in the Internet of Things (IoT) system. It can be any device that collects data from its surroundings, such as a sensor measuring temperature, a smartwatch tracking health data, or a security camera monitoring surroundings.

What makes these devices ‘edge’ is their ability to process and analyze the data they collect right there on the spot, instead of sending all the data to a central server or cloud for processing.

For instance, an IoT edge device could be a sensor in a manufacturing plant monitoring equipment, a wearable device tracking health metrics, or a component in a self-driving car analyzing real-time traffic data. In all these cases, the edge device is responsible for collecting data and making sense of it right where it’s generated.

Practical Applications of IoT Edge Devices

The use cases for IoT edge computing are as varied as they are critical. One important use case is autonomous vehicles. Here, IoT edge devices process a massive amount of data from sensors in real-time, making instantaneous decisions that can have life-or-death implications. This includes analyzing traffic conditions, identifying pedestrians, and responding to unexpected events, all requiring low latency that only edge computing can provide.

The healthcare industry uses IoT edge devices in wearable technology and remote monitoring equipment. These devices collect, process, and analyze data in real-time, offering insights into a patient’s health and enabling rapid response to emergencies.

The manufacturing industry is another area where IoT edge computing shines. IoT edge devices on factory floors can monitor machine performance, predict maintenance needs, and even automate processes. This real-time data processing can significantly increase efficiency and productivity, reducing downtime and waste.

Securing the Future: Enhancing IoT Security at the Edge

As IoT and edge computing evolve, security remains a paramount concern. With the exponential growth of IoT devices, the attack surface for potential cyber threats has expanded significantly. Therefore, securing IoT at the edge becomes critical to maintaining interconnected systems’ integrity and protecting sensitive data.

IoT security involves implementing protective measures at every stage of the IoT ecosystem, from the devices themselves to the network and the data they handle. Due to their diversity and the massive scale of deployment, IoT devices can often become weak points vulnerable to cyberattacks.

An IoT gateway serves as a critical component in enhancing the security of IoT at the edge. These gateways act as intermediaries between IoT devices and the cloud or data center.

They can provide a robust security layer by offering functions like encryption, identity management, and secure data transmission, protecting sensitive data from potential breaches.

Other crucial considerations in securing IoT at the edge involve:

  • Regular security updates and patches.
  • Ensuring the use of strong, unique passwords.
  • Employing secure protocols for device-to-device communication.
  • Incorporating a strong, layered defense strategy that considers potential threats at every level.

Final Thoughts

The convergence of IoT and edge computing is not merely a technological trend; it’s a strategic transformation set to redefine the digital landscape. But as we move towards a more connected world with IoT and edge computing, it is crucial to prioritize security. With proper strategies and tools in place, we can reap the benefits of these technologies while minimizing the risks.

July 2023: What’s New?

“What’s New?” is a series of blog posts covering recent changes to Comet in more detail. This article covers the latest changes in Comet Voyager over July 2023. 

There were five Comet software releases during July – one in our quarterly 23.5.x Thebe release series, plus four releases in the 23.6.x Voyager release series.

Single sign-on with Microsoft, Google, and OIDC​

Comet Server is adding support for administrators to single sign-on (SSO) to the Comet Server web interface, using a supported OpenID Connect (OIDC) identity provider:

OIDC is a framework for authentication and authorization, based on the OAuth 2.0 standard. It’s widely used by many providers for “Log in with…” buttons. This new feature extends our existing single sign-on support using the LDAP protocol.

The additional identity providers (IdPs) now supported are:

  • Microsoft Entra ID (formerly Azure AD)
  • Google (Google Cloud, Google Workspace, or personal)
  • Any other OIDC-compatible provider that uses a discovery document (usually at the .well-known/openid-configuration URL path).

You can configure a new OIDC provider from the Comet Server web interface > Settings screen > “Admin Accounts” tab > “External Authentication Sources” button:

To use this feature, you should first visit your IdP’s settings page, register a new application credential within the IdP, and copy the credentials to this settings page. You will then need to copy Comet’s generated “Redirect URI” field back into your IdP’s settings page.

When the administrator user uses the new “Log in with…” button and performs a successful login operation via the IdP, a new Comet Server administrator account will be dynamically created for them on-demand. As with LDAP, you can specify which Comet Server permissions are granted to the newly generated account. This new account is marked as “Externally managed” within the “Admin Accounts” table, ensuring that valid IdP login is required to access this administrator account.

If your IdP enforces two-factor authentication (2FA), you can configure Comet Server to skip enforcing its own internal 2FA on the account, so that the user is not bothered twice.

You can request custom scopes, and enforce claim values against either custom scopes or standard OIDC scopes. This allows you to enforce that the only members of certain Microsoft, Google, or OIDC groups within your IdP are allowed to log in to the Comet Server.

This feature is available both for the top-level Comet Server administrator as well as individually for each tenant.

Price change notice for Comet Storage powered by Wasabi

Our Comet Storage service gives you the option to purchase Wasabi Cloud Storage directly from Comet, offering all-in-one billing and providing a more integrated experience. This month, we’ve passed along the latest price changes from Wasabi, to their new price of $6.99 / TB.

For more information, please see Wasabi’s official announcement.

Improved job start performance

When backing up a Files and Folders-type Protected Item, one of the first steps is for Comet to enumerate all the selected files, in order to calculate their total size. The total size is used to enforce the “All Protected Items Quota” feature, as well as to properly determine the progress bar’s expected upper bound. If you are running a headless device with no GUI to render the progress bar, and you are not using the “All Protected Items Quota” feature, then there’s no remaining purpose for this scan phase, and so Comet will skip it to save time.

We heard mixed feedback about this – a discussion in our feature voting system uncovered some use-cases where the progress bar would still be desirable even on headless devices with no GUI. But also, there was competing feedback that spending time on file size measurement is still slow and undesirable even in some cases where the GUI was present.

In the latest version of Comet, we’ve come up with a new and better approach to this issue. If the “All Protected Items Quota” feature is used, then we require an accurate measurement up-front regardless. But if this feature is not used, then we can rapidly create an approximate progress bar size based on the previous backup job’s size plus some small estimated buffer amount. This should provide a great speed improvement for GUI users, a reasonable progress bar for headless users, and at the same time, provide an accurate measurement for quota users. The reported size measurement will always be completely accurate after the backup job finishes.

Improved low-memory modes

For users using Comet on devices with low RAM, our software has long since offered the “Prefer temporary files instead of RAM (slower)” option for backup jobs, to toggle whether Comet stores the deduplication index either in-memory or on-disk in a temporary database file. Enabling this option can significantly reduce Comet’s memory usage, allowing the backup job to complete on low-memory devices, at the expense of a longer backup job duration.

The latest version of Comet extends this option to also use a small in-memory bloom filter. This allows Comet to perform some of the deduplication operations in-memory with minimal overhead. This new combination technique can significantly improve the performance of this option for low-memory devices.

The deduplication index is needed for almost all operations involving the Storage Vault, not just backup operations. This month, we’ve also added an option to use temporary files instead of RAM during a restore, extending the possible use cases for Comet on low-memory devices.

Performance improvements for new servers

The performance improvements this month are not limited to the Comet app itself. We’ve also significantly improved the account.cometbackup.com system: downloading the large Self-Hosted Comet Server installer is now implemented via an Amazon CloudFront cache, improving download speeds between 2-6x in our testing.

We have also been able to significantly improve the speed of creating new Comet-Hosted Comet Server instances. The creation time has been reduced from 60-90 seconds down to 10-15 seconds, owing primarily to some changes in the default generated DNS names.

Configuration change notice for PKCS11 codesigning

Comet supports Authenticode codesigning for Windows using either an on-disk file (PKCS #12), or a hardware security module such as a USB device (PKCS #11), or a cloud HSM on Azure Key Vault. With the file-based approach no longer being supported for new Authenticode certificates, we are seeing increased use of the alternative PKCS #11 and Azure Key Vault options, as partner Authenticode certificates come up for renewal.

If you are using a physical USB device for Authenticode codesigning, we have updated the available settings options to improve compatibility with a wider range of devices. The new settings screen should be clearer and easier to use, but you may be required to update your configured settings, as depicted:

If your Comet Server is running in a cloud VM, it’s not feasible to plug in a USB hardware device for codesigning. We would recommend Azure Key Vault as an excellent cloud-based solution to this issue, but we’ve also recently tested the compatibility of the third-party Virtualhere software for remotely forwarding a physical USB device to another PC, and we can confirm this solution works for PKCS#11 codesigning when running Comet Server on a cloud VM.

When using the Comet Server web interface, the quick search bar (using the Alt + Q keyboard shortcut) could previously search through usernames, Account Name field values, Protected Item and Storage Vault names, settings pages, and more. In the latest version of Comet, we have extended the search capabilities to also find users by their email address.

You can also now enter the ID of a Protected Item, Storage Vault, or even a backup job, and the quick search bar will try to match it with the corresponding user or job. This is particularly helpful for troubleshooting some situations.

That’s all for this month – the blog will return next month with more news about all the latest changes to Comet.

Why NACs are inadequate for cyber asset management

Asset inventory is foundational to security: before you protect a device, you must know about it. You may rely on data from your network access control (NAC) and associated network aggregation tools to provide your asset inventory. However, if you’ve found compromised assets but can’t find them in your asset inventory, you may have realized that NACs aren’t the best at asset discovery. Allowing or denying access to the network on Layer 2 is their primary function, but finding everything on your network is a different problem. Let’s examine why.

NACs have limited visibility to endpoints on the network #

Cyber asset management aims to maintain a complete inventory of everything connected to your network, from IT to OT, cloud to remote devices. NACs, such as ISE, FortiNAC, CounterACT, and Portnox, employ discovery methods that miss and mis-fingerprint devices.
  1. Listening to broadcasts NACs listen for endpoint attributes directly via a couple of broadcast protocols: CDP/LLDP and DHCP. Cisco Discovery Protocol (CDP) and its vendor-agnostic cousin Linked Layer Discovery Protocol (LLDP) primarily provide information about networking devices or phones only. The standard Dynamic Host Control Protocol (DHCP) only provides information about an endpoint’s IP address, operating system, and MAC addresses.
  2. Direct network calls NACs collect attributes from individual hosts rather than a network-wide scan. They use many protocols: DNS, HTTP, RADIUS, and SNMP. Remote Authentication Dial-In User Service (RADIUS) also provides low-level information like MAC, IP address, and location information. Domain Name System (DNS) only provides information about hostnames and IP addresses. If a web service exists, Hypertext Transfer Protocol (HTTP) can provide additional details like application type, operating system, software vendor, and software revision. DNS and HTTP must work alongside other discovery methods since NACs require IP-to-MAC mappings for each endpoint.
  3. Nmap Nmap is the gold standard for ad-hoc network scanning. Network discovery and security auditing are frequent use cases for this free and open-source utility. However, it has some challenges for general asset discovery at scale.
  4. Passive network monitor Deploying one or more appliances on a network to eavesdrop on network traffic is a common technique. To make it work, you must send network traffic to the appliance(s) through switch reconfiguration or tap insertions. It’s important to note that network location matters. Eavesdropping at a network “choke point” is ideal since it ensures visibility into all traffic. However, the fingerprints lack precision and accuracy if an asset rarely talks on the network or is terse. As more devices encrypt traffic, the fingerprinting accuracy gets worse.
  5. NetFlow NetFlow is a (marginally) cheaper and easier alternative to a passive network monitor. It collects and stores only Layer 2-4 information, such as source and destination IP and ports, as well as MAC address.
  6. Agent All NAC vendors provide agents (e.g., AnyConnect, FortiNAC agent, SecureConnector, AgentP). Even NAC solutions that claim to be agentless include them. Running software on the endpoint provides a wealth of details that help NACs apply granular policies, which works well for managed devices if IT can install the agent.
  7. Credentialed queries Some NAC will log in to a device via Windows Management Instrumentation (WMI) to profile it. Similar to agents, this approach gives a lot of details. Unfortunately, you need to know the credentials first, which means this only works well for managed IT devices.
Note: Organizations rarely use CDP and Nmap in production for NACs, but I’ve included them here for completeness.

Incomplete asset inventory: why NACs fall short #

The current methods of discovery may overlook assets and incorrectly identify them. Broadcasts aren’t propagated over the network and don’t give a broad view of assets. Direct network calls and Nmap (as used by NACs) only provide additional details about devices already known to the NAC. Passive network monitors and NetFlow collectors, despite the effort invested, provide limited detail. Agents are great, but only for managed IT devices.
  1. Unmanaged IT machines NACs do not cover these servers, laptops, and desktops. Either the installation got missed, or nobody knew that these machines existed. The other methods won’t tell you much more than an IP address, MAC address, and operating system.
  2. Corporate IoT Offices contain many IoT devices that can’t install an NAC agent because the platform is not supported. The NAC uses alternative discovery methods to identify a device only as a Linux machine or an IoT platform device (such as Espressif or Raspberry Pi). But they could be anything. Think of your printer, IP phone, video conferencing device, thermostat, surveillance camera, and door controller that lets you in when you swipe your access badge. Knowing the hardware matters in a security investigation.
  3. OT equipment Usually, industry-specific operational technology (OT) includes warehouse technology, production lines, biomedical equipment, and energy transmission. A programmable logic controller (PLC) that controls the production-line robot does not support installing an agent.
Here’s an example of device details detected by a leading NAC:
  • Hostname: dev
  • Operating system: Windows 7 SPI1
  • VLAN: 77
  • Current switch: 1.1.1.1
  • Connection: Up
  • Location: Office
  • First Seen: 05/24/2023 at 10:39 AM
  • Last Seen: 05/24/2023 at 10:39 AM
  • IPv4 Address: 192.168.40.248
  • MAC Address: 00:0c:29:59:c4:65
Asset information from leading NAC includes the IP and MAC addresses and the network location of the discovered device.
By contrast, runZero provides a great deal of detail by default:
runZero shows much richer information about networked devices than NAC profiling (without agents).

Missing devices or mis-fingerprinting them become even more problematic when using NACs for enforcement. Suppose a NAC incorrectly identified an IP camera as a Linux server. Your NAC is applying policy to a camera when it’s clearly not.

Underutilizing NAC features to handle all types of devices #

Allowing and denying access to individual endpoints is a central selling point for NACs and an essential control as part of a larger zero-trust networking strategy. Organizations do one of two things to meet the challenge of partial asset inventory and vague fingerprinting regarding their NAC.
  1. Partial enforcement Without a full and accurate asset inventory, you risk booting legitimate, business-critical assets off the network. Many organizations selectively enforce based on the relative number of unmanaged devices. Enforcement is commonplace on wireless segments, more miss than hit on wired IT segments, and rare on OT segments.
  2. Exclude MAC addresses Organizations that attempt enforcement at scale must maintain a list of MAC addresses that bypass enforcement control. Keeping that list up to date is time-consuming and error-prone without a bespoke tool, which accents the depth of the problem, especially in OT environments.

NAC focuses on the LAN #

The security posture of a device viewed by the attacker is not in the scope of a NAC. They adjudicate network access which worked well in a time when most of an organization was in the corporate office. A cyber asset management solution, on the other hand, provides an inside-out and outside-in view of the inventory. This view includes the external attack surface of an asset, which can be valuable information, such as when RDP is active on a public IP.

Risks and slowdowns due to missing devices #

If you are missing assets in your inventory, you can’t actively manage your security posture. You can only successfully find EOL devices, insecure configurations, and vulnerabilities if you know about all your network’s devices. Asset inventory gaps can impede quick action by causing delays when identifying potentially compromised devices on specific IP addresses. Still, you can’t figure out what that device is. You lose valuable hours while the bad guys get deeper into your network. An accurate, complete cyber asset inventory is crucial.

A cyber asset management solution that covers assets from IT to OT, cloud to remote devices #

runZero is a cyber asset management solution that includes CAASM functionality. It combines integrations with EDR and other sources with a proprietary network scanner that is fast and safe even on fragile IoT and OT networks. runZero scales up to millions of devices, but it’s easy to try. The free 21-day trial even downgrades to a free version for personal use or organizations with less than 256 devices. Find out what’s connected to your network in less than 20 minutes.

About runZero
runZero, a network discovery and asset inventory solution, was founded in 2018 by HD Moore, the creator of Metasploit. HD envisioned a modern active discovery solution that could find and identify everything on a network–without credentials. As a security researcher and penetration tester, he often employed benign ways to get information leaks and piece them together to build device profiles. Eventually, this work led him to leverage applied research and the discovery techniques developed for security and penetration testing to create runZero.

Cybersecurity tips for small businesses

When a massive data breach happens, large companies usually grab the headlines. However, it’s often the case that small businesses are attacked more often and are more vulnerable to cyberattacks. Their limited security measures due to their smaller size create better odds for an attacker.

For this reason, prioritizing security against these threats should be crucial for business owners. Effective security measures can help safeguard vital data, maintain customer trust, and prevent costly cyber incidents. This article discusses essential cybersecurity tips for small businesses to enhance their security posture.

Best practices for small businesses

A successful cyberattack puts business revenue, data, and equipment at risk, but it doesn’t stop there. Cybercriminals may also use their access as a launchpad into the networks of other companies connected to your business.

Small businesses lack the resources of corporations, but cybersecurity must still protect data, internet connection and network resources. With a lot at stake, here are some industry best practices to help you navigate the world of cyber threats.

Conduct a thorough risk assessment

Your cybersecurity plan should start with assessing the risks your business faces. Timely identification of potential vulnerabilities helps put the risk in perspective and assess the impact of cyber threats on critical data. This is the foundation for all further actions.

A comprehensive risk assessment helps prioritize security efforts and effectively allocate resources. That way, the key areas will be taken care of sooner rather than later, which enables businesses to patch up the weakest points first and then move on to less critical areas. It lays the groundwork for a solid cybersecurity strategy.

Create an Incident Response Plan

Preparing for a cybersecurity incident can help reduce the impact when a business falls under a cyberattack. While neutralizing active threats is a priority, so is restoring normal working conditions. This allows it to continue business operations as if the cyberattack was merely a setback.

To prepare, there are two main areas to focus on:

  • Calculate risk probability for threats. Include an assessment of where critical data resides. Assign an individual responsible for protecting important data and connecting every resource with risk-reduction strategies.

  • Create a recovery plan for all critical assets. This should include security scans to identify malware or virus infections. Document access requests during security alerts and determine whether data loss has occurred.

An Incident Response Plan (IRP) is vital for prompt and effective handling of cyber incidents. It should also include contact information for key stakeholders, guidelines for containing and investigating the incident, and a plan for communicating with customers and authorities.

Keep software and systems up to date

Regularly updating operating systems, applications, and software is necessary to avoid cyber threats. Cybercriminals often exploit gaps in outdated software, so staying current with patches is a sure way to stop some attacks right in their tracks.

Software updates also address bugs and glitches that may affect the software’s performance, stability, or functionality. So, in addition to increased security, updates typically include bug fixes that improve the overall user experience and resolve known issues.

Implement a strong password policy

Weak passwords are common entry points for cyberattacks as they’re easy to guess or brute force. That’s why it’s important to make sure that your employees use strong passwords: a combination of uppercase and lowercase letters, numbers, and special characters.

Passwords should also be unique for each account. Enterprise-wide password management tools can help. They make storing and changing passwords easier, eliminating the risk of human error. This allows to avoid password reuse, which could compromise a user account if other accounts sharing the same password are breached.

As an additional precaution, passwords should be periodically updated to limit the time when criminals could exploit them.

Limit access to sensitive data and systems

Access to sensitive information and critical systems should be provided only on a need-to-know basis. This means that users should have minimum access rights. Elevated privileges should be assigned under special conditions and for separate user account types. Such a setup minimizes insider threats and contains damage in case of a data breach.

User permissions should also be regularly reviewed, ensuring only authorized personnel can access sensitive data over an internet connection. Quickly disposing of inactive and zombie accounts helps clean up your user base and establish that only authorized users can access sensitive data.

Implement two-factor authentication or multi-factor authentication

Small companies need to secure the network edge with robust authentication procedures. Two-factor authentication or multi-factor authentication are the best options here. These methods require multiple identification factors whenever users connect to network assets. This makes it far harder to obtain access illegitimately.

If MFA is too burdensome for employees, consider using it solely for administrator accounts. Alternatively, try user-friendly 2FA options such as fingerprint scanning. Balance user experience and security. But always go beyond simple password protection, as even strong ones can benefit from additional layers of protection.

Use network security measures

Technological solutions can help to secure business networks, making it harder for external penetration. A robust firewall, antivirus software, intrusion detection systems, and virtual private networks (VPNs) are a good starting point to tighten security around your network perimeter.

The network is the main channel for data exchanges and communication, so its security is key for business continuity. Firewalls provide a barrier between your internal network and the internet, while intrusion detection systems can alert you to potential cyber threats. VPNs encrypt internet connections, ensuring data privacy and protecting against unauthorized access. Meanwhile, antivirus software is a good all-rounder that helps to deflect simple network threats.

Implement protection for sensitive information

No matter where sensitive information is kept or transferred, appropriate security measures should be in place.

  • Encrypt high-value data such as personnel records and customer financial information. If you rely on SaaS or PaaS tools, use any cloud data protection tools provided by your Cloud Service Provider.

  • Use privileges management to limit freedom within network boundaries. Confidential data should only be available to users who need it for their tasks. That way, attackers struggle to access and extract data when a data breach occurs.

  • Minimize the number of users with administrative privileges. Avoid giving single users the authority to make fundamental network changes.

  • Consider using Data Loss Prevention tools as well. These tools track the location and state of important data. They block data transfers to unauthorized devices and log potentially dangerous access requests. DLP could be a sound investment if you handle high-risk and high-value data.

These measures add an extra layer of security and prevent sensitive data from falling into the wrong hands.

Train employees on cybersecurity best practices

Digital cybersecurity controls rely on human knowledge and behavior. How employees act when encountering cyber threats is crucial to a small business security setup. That’s why it’s vital to focus on what is known as the human firewall.

Strengthen the human firewall by instructing employees how to spot phishing emails and malicious links. Invest in employee cybersecurity training to create a security-conscious culture within your organization. Educate them about common cyber threats, phishing attacks, and social engineering techniques (don’t forget the importance of strong passwords).

Remote workers should also understand secure connection practices and the risks of using an insecure public Wi-Fi network. Regular training sessions and reminders will help foster a security culture within and outside the organization.

Stay compliant

Stay informed about relevant data protection and privacy regulations for your industry and location. Ensure your business complies with laws such as the General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA). Compliance helps protect your business from legal consequences and demonstrates your commitment to data privacy.

Regulatory requirements are subject to change, so monitoring their developments should be ongoing. This allows to be prepared for any relevant changes in advance and align with applicable data protection and privacy regulations.

Schedule regular backups

Cyber attacks can lead to the deletion of data or system failures that compromise workflows. This makes it vital to back up high-priority data regularly. Use secure cloud services or external locations outside your core network for automated data backup.

The data recovery process should be periodically tested to ensure the integrity and availability of your backups. If this system is effective, it will quickly bounce back from all internal and external threats with minimal downtime.

Manage third parties securely

Small businesses rely on third-party vendors, but these partnerships can be vectors for cyber attackers. For example, CRM providers may not encrypt data securely, putting client data at risk. Virus checkers or low-quality VPNs may transmit spyware.

Check all third parties and ensure they have rock-solid security policies. Trust nobody and always ask for security assurances when in doubt. Evaluate their security practices, including data handling, access controls, and incident response procedures. Establish clear cybersecurity expectations in vendor contracts and regularly monitor their compliance.

Regularly review and update the cybersecurity plan

As cyber threats rapidly evolve, your cybersecurity plan should be periodically reviewed to address various changes. Small businesses, in particular, should stay informed about emerging threats and security best practices.

Conduct periodic audits and risk assessments to identify any gaps or weaknesses in your security strategy and take prompt action to address them. If done consistently, this helps to keep threats at bay and your business operations uninterrupted.

Key takeaways

Let’s recap some of the key insights on cybersecurity for small businesses.

  • Small businesses are often more vulnerable to cyberattacks than large corporations due to limited security measures. Small businesses must prioritize cybersecurity to protect their vital data, maintain customer trust, and prevent costly cyber incidents.

  • A thorough risk assessment should be step one of your cybersecurity plan. It helps to identify potential vulnerabilities and assess the impact of cyber threats on critical data.

  • Incident Response Plan (IRP) helps to prepare for cybersecurity incidents. It should include risk calculations, data protection responsibilities, recovery plans for critical assets, and guidelines for containing and investigating incidents.

  • The majority of cybersecurity risk management deals with ongoing maintenance. Keep software and systems updated, use network security measures, and conduct regular employee training sessions.

  • Implement industry-wide best practices such as the principle of least privilege, multiple-factor authentication, and rules for strong passwords to navigate the dangerous cyber landscape.

By following these cybersecurity tips, small businesses can enhance their security posture, mitigate risks, and protect their data and assets from cyber-attacks.

Visibility – an Essential Part of Cybersecurity

Visibility is key to protecting our networks. But what exactly is visibility and why is it important?

Visibility means having a clear understanding of what’s happening in your network at all times. That means you can continuously verify what you see in your policies and best practices, immediately catching configuration issues, vulnerabilities, irregularities in security protocols, and user behavior. You also gain knowledge in the area of network performance and services as well as their availability.

By having visibility, you can act preventively, and systematically strengthen your network’s resilience to intrusions and reduce the room for maneuver for potential attackers. It also allows you to observe traffic in all relevant locations and network segments, whether on local networks, servers, or in the cloud.

So, how can you achieve perfect visibility?

One tool that can help is GREYCORTEX Mendel, which provides real-time monitoring and visualization of all communication in your network. It builds a mathematical model of your network and helps you determine what devices are communicating with each other, when, and how much data they’re sending and receiving. In Mendel, you can read details about used protocols for communication, including analysis of application data, or user identities. This provides detailed context and additional information about security events and threats.

Visibility is also crucial for managing any OT/SCADA network.

An up-to-date and accurate knowledge of what elements are involved in these communications, and what appears or disappears in them is invaluable, if only from an operational point of view. On top of that, GREYCORTEX Mendel understands OT/SCADA protocols, which brings visibility to critical control parameters such as temperature, RPM, voltage, or any other relevant factor in the data transmitted over the network. This adds more visibility into the processes in operation and provides an additional opportunity for the prevention of and response to abnormal events.

It does not stop here. GREYCORTEX Mendel goes a step further in this visualization. Thanks to advanced filtering, combining a number of parameters and using local operators, you can examine each device and its communication also to the smallest details as well as in the history. That makes root cause analysis, threat hunting, and network troubleshooting simple. This has also been confirmed by SOC teams that found Mendel an invaluable tool for post-hack analysis and prevention activities.

In short, visibility is an essential part of cybersecurity, and tools like GREYCORTEX Mendel can help you achieve it. By clearly understanding what’s happening on your network at all times, you can take preventive measures to strengthen your network’s resilience and protect against potential attacks.
