Enterprise cybersecurity protects company applications, data, and infrastructure from online threats. It protects local networks, cloud assets, and remote devices and aims to bolster enterprise security by countering hackers. By doing so, it minimizes the risk of data breaches.

This article will explain the scope and role of enterprise cybersecurity. We will look at some of the most recent cyber threats, as well as best practices to neutralize those dangers. And we will finish with a quick cybersecurity checklist to make implementing changes easier.

Why is enterprise security important?

Enterprise cybersecurity matters because companies must focus on data and network protection. Aside from that overarching need, there are several reasons to make cybersecurity a corporate priority:

• Data breaches. Recent years have seen a rapid acceleration in the frequency and scope of data leaks. Countless small businesses have suffered, and many have gone out of business. Enterprise security excludes malicious actors and reduces financial and reputational damage.

• Multi-layered protection. Enterprise cybersecurity creates a series of connected enterprise network defenses. This makes life far harder for would-be attackers. The more time it takes to access critical data, the lower the chances of hackers succeeding.

• Risk management. Cybersecurity strategies systematically consider every aspect of data protection. Planners gain maximum awareness of network architecture. This includes connected devices, user behavior, identity management, threat detection, and data integrity.

• Secure business growth. Enterprise cybersecurity helps businesses scale safely. Adding new branches, employees, and applications can compromise cybersecurity. Robust security measures accompany every network expansion, allowing stress-free long-term growth.

• Third-party management. Enterprise cybersecurity assesses and manages third-party risks. Companies can choose secure partners and work safely to achieve their business goals.

• Company-wide learning. A solid strategy for cyber security companies educates employees and strengthens the overall security posture. Without an enterprise-wide security plan, employees may miss phishing or authentication training.

Overview of common cyber threats for large organizations

The first step in solving enterprise cybersecurity worries is understanding critical threats.

An effective cybersecurity strategy assesses the risks from critical threats and implements controls to neutralize them.

Social engineering (Phishing)

Most data breaches start with a social engineering attack. Attackers persuade their targets to click malicious attachments. Or they entice users to visit websites infected with malware. They might send emails purporting to come from trusted co-workers or trusted partners. In some cases, phishing attacks involve phone or video conversations to build trust and plan attacks.

Phishing attackers work hard to create believable personas and stories. Only well-trained employees can spot their activities, which are hard for automated tools to detect. So building phishing awareness is an enterprise cybersecurity priority.

Malware

Malware is malicious software that disrupts networks and extracts valuable data. There are many different forms.

Ransomware locks applications until targets pay attackers. Spyware infects networks and sends information to malware operators. Trojans look legitimate but actually implant hazardous code. And worms replicate automatically throughout your network, causing havoc as they spread.

Advanced persistent threats (APTs)

APTs are a specific form of malware with special relevance for enterprise cybersecurity. These threats remain resident on network infrastructure for long periods. For instance, the APT in the 2018 Marriott data breach was present for four years. In that time, it extracted vast amounts of sensitive information, with catastrophic results.

APTs are harder to detect than most malware agents. Companies need advanced detection systems to block, discover, and neutralize persistent threats.

Distributed denial of service (DDoS) attacks

DDoS attacks use bots to direct huge floods of traffic at network devices. Sudden traffic bursts can override network defenses and take down hardware. This results in downtime and lost activity. But the effects can be even worse.

In some cases, these attacks cover malware attacks. Attackers use the traffic flood to enter networks undetected. Enterprises need ways to cut the risk and consequences of botnet attacks.

Insider threats

Company insiders also pose an enterprise cybersecurity risk. Employees can assist phishers by providing information such as personal data or contact details. Many “whaling” attacks on executive-level targets start this way.

Disgruntled workers can extract data and sell it on the dark web. They could send project files to competitors or disrupt workflows via sabotage.

Third-party risk management

Most companies work with third parties to run their infrastructure and deliver services. But any third party could become an enterprise cybersecurity problem.

Third parties could use excessive privileges to extract sensitive data. They could accidentally provide login credentials for malicious outsiders. Both are potential security disasters.

Risk management is essential. Assess third parties and make them follow company security policies. Be careful when acquiring overseas assets. Acquired divisions or smaller companies could pose a security risk.

Best practices for enterprise cybersecurity

Use MFA for all users

The first critical enterprise security measure is robust authentication. Ask for more than one authentication factor when users log in. You could use biometric scanners, one-time password tokens, or smartphone authentication. Find a style that fits your workforce needs.

Prioritize administrative accounts with the greatest privileges. When attackers access them, they can roam freely and inflict the greatest damage. Make high-privilege accounts as hard to access as possible.

Extend MFA to mobile apps and remote access APIs. Enforce strong passwords for every user. Deliver password policies to all devices when they come online. Automate offboarding procedures to delete accounts when employees leave.

Use IDS/IPS to detect threats

Add another enterprise cybersecurity layer by installing Intrusion Detection Systems (IDS) or Intrusion Prevention Systems (IPS). IDS and IPS perform roughly the same role. They operate continuously and track traffic flowing through the network. They detect threats rapidly by comparing traffic to global threat databases.

IDS/IPS tools also alert managers about unauthorized file transfers. They flag unusual changes in administrative privileges. And they determine whether sudden network slow-downs are connected to cyber attacks.

Prevention systems powered by machine learning let you automate threat detection. They are not a replacement for firewalls and antivirus tools. Instead, IDS/IPS tools are valuable to the enterprise security arsenal.

Carry out regular security assessments and penetration testing

Enterprise security requires testing to make sure security systems are effective. Regularly monitor and test your security systems to uncover network vulnerabilities.

• Check endpoint security. Are remote devices covered by VPNs and authentication systems? Do you have full awareness of all connected endpoint devices?

• Check web assets for code flaws. Any minor mistakes could enable SQL injection attacks.

• Assess updating policies. Are critical apps and devices updated in a timely fashion? If not, you could face a higher risk from Zero Day Exploits.

• Assess partner organizations carefully and vet their security processes. Put in place systems to detect suspicious activity, such as “impossible logins” from many locations.

• Audit privileges management systems. Role Based Access Controls (RBAC) segment networks and limit access to critical data. Regularly assess user permissions to avoid privileges creep.

• Penetration testing also helps you understand how attacks occur. They simulate intrusions, providing insights about weaknesses and areas to improve.

Implement data encryption

Encrypt confidential data at rest on your network and in motion between network endpoints. Use a Virtual Private Network to protect remote access devices and encrypt data flows. Leverage encryption tools provided by cloud service providers.

For watertight data security, consider using end-to-end data protection software. Data security tools encrypt files wherever they move. Systems track the location of data and who is accessing it. And they block unauthorized removal from network settings. This level of protection makes it far easier to comply with data security standards like CCPA or GDPR.

Prioritize crisis management

Planning for emergencies is a core part of enterprise cybersecurity. Assume that data breaches will happen. Put procedures in place to respond and restore network operations as quickly as possible.

A good approach to crisis management is to identify, react, and rebuild:

• Identify threats immediately with cutting-edge threat detection software

• React straight away. Inform clients if their data is at risk. Quarantine malicious agents and assess the scope of any data breaches.

• Rebuild business operations safely. Use data backups to restore web portals and SaaS apps to their previous state. Audit security weaknesses and check for APTs. Communicate clearly with customers. Be transparent about the measures you are taking.

Data backup and post-incident reviews

Data backups restore operations and safeguard customer data. Choose a secure cloud or off-site backup provider to store critical data. If possible, store more than two copies of high-priority files, and make daily backups of the most valuable data.

Enterprise cybersecurity does not need complete backups of other company data. That would become hard to manage at scale. But it’s a good idea to incrementally back up critical application workloads. Store enough data to restore systems following a security incident.

It’s also important to review disaster recovery processes after cyberattacks. Assess whether data backups were effective and secure. Track the speed of system restoration and any data corruption following restart.

Solutions for enterprise cyber security

What are the best solutions to the enterprise cybersecurity dilemma? It makes life easier if we break down enterprise security into three core areas.

Network security

Companies need to ensure secure access to network resources. Network security solutions include:

• End-to-end encryption of all critical data

• Endpoint protection via remote access VPNs

• Single Sign On and MFA systems to exclude unauthorized users

• Antivirus and antimalware tools

• Password management to strengthen credentials

• Employee training to detect phishing

• Security policies are distributed to every endpoint

Cloud security and data protection

Enterprise cybersecurity must lock down cloud assets and the data held in cloud environments. Solutions here include:

• Privileges management to limit access to resources employees need

• Cloud VPN systems anonymize users and encrypt data in motion

• Cloud-native firewalls regulate access and block threats

• Use of encryption provided by CSP

• SD-WAN architecture covering all network assets

Use of security information and event management (SIEM) systems

SIEM tools proactively track threats across enterprise networks. This extends beyond basic network security. SIEM solutions include:

• IDP/IPS systems to actively detect threats

• Use of global threat intelligence to combat the latest vulnerabilities

• Machine learning to achieve granular threat detection

• Forensic dashboards for full security visibility

• In-depth reporting for security development and compliance audits

Small businesses are on the front line of cybersecurity. At any moment, cyberattacks could extract confidential data, damage network infrastructure, or even cause total business failure.

The risks are real. According to Verizon, 60% of small businesses that suffer cyber attacks go out of business within 6 months. Healthcare company Wood Ranch Medical is a great example. The small operator was bankrupted by a 2019 ransomware attack that prevented access to sensitive patient records.

Despite cases like Wood Ranch Medical, most small businesses fail to allocate enough time and resources to counter cyber-threats.

Don’t fall into that trap. Instead, follow this guide to implement robust cybersecurity measures. With our help, you can counter the most dangerous cyber threats faced by SMBs. Let’s find out more.

Understanding the threat landscape for SMBs

The first thing to understand is that small businesses face a diverse range of cyber threats. Any one of them could ruin your reputation and lead to regulatory fines.

Attackers can lurk for months and monitor traffic. They can steal sensitive client data or lock it away until victims pay a ransom. Or they could cause technical damage, ruining network infrastructure.

SMBs can’t afford these consequences. But how do you handle critical cybersecurity threats?

Prevention starts from awareness of the most common threats and how they fit into cybersecurity for small businesses.

Types of cyber attacks

Here’s a list of the most common types of online threats.

1. Phishing

Phishers use social engineering techniques to fool small business employees. With a few pieces of information, attackers can easily convince time-poor workers to make dangerous decisions. This might involve emails pretending to come from colleagues or trusted third parties. The links in these emails lead to malicious sites or initiate malware downloads.

2. Ransomware

Ransomware locks down high-value data and demands a ransom from targets. If attackers control these targets, they can demand a high price to restore access. And small businesses are not always able to pay.

3. Spyware

Spyware tracks data flowing through network assets and sends this information to controllers outside the targeted organization. Some spyware is legitimate. For instance, advertisers sometimes use it to deliver targeted ads. But the majority of spyware is malicious and linked to data extraction.

4. Viruses

Viruses spread between devices and their effects range from relatively light disruption to complete system failure. Some viruses remain dormant for long periods. Others set to work immediately. In all cases, small businesses need updated and effective antivirus software to defend their perimeter.

5. Malware

Malware extends beyond ransomware and spyware. For example, businesses might encounter trojans or worms that stay below the radar until activated. Bots are also common. These agents latch onto devices and create “swarms” to launch wide-scale attacks.

6. Man-in-the-middle attacks

Man-in-the-middle attacks target insecure wifi connections. Attackers can intervene between remote access workers and the corporate network. If the connection is unencrypted, hackers can harvest information from corporate network traffic and steal confidential data.

7. SQL injection

SQL injection uses SQL code to request access to valuable databases. This generally occurs via web forms connected to SQL databases. For small businesses, this could include employee gateways or payment forms. Securing web assets is absolutely essential.

8. DDoS attacks

Distributed denial-of-service attacks involve botnets featuring hundreds or thousands of agents. Botnets direct massive amounts of traffic at their target with the aim of overwhelming networks. Larger organizations may have the resources to absorb DDoS floods. But with attacks averaging 5.17 Gbps, small business websites can easily fold under the pressure.

9. Zero-day exploits

Zero-day exploits target recently documented software vulnerabilities. In these situations, vendors probably haven’t developed patches, exposing users to opportunist attackers. Small businesses rely on anti-virus, communications, and data management tools in everyday work. But any of these tools can become vulnerable overnight.

10. DNS tunneling

DNS tunneling injects malicious code into networks via DNS queries. This allows hackers to seize control of local DNS servers. When that happens, a small business can lose control of its website and network assets. DNS tunneling exploits insecure firewalls, but SMBs often retain legacy firewall products. That’s a bad idea when successful attacks can ruin reputations in seconds.

11. XSS attacks

XSS (or Cross Site Scripting) injects malicious code via web applications and browser-side scripts. XSS attacks allow attackers to change website designs, adding undesirable content. They can launch malicious software, infecting business networks and customer devices. It allows hackers to spoof legitimate identities by hijacking cookies. All of that is bad news for SMBs.

Cybersecurity best practices for small businesses

Small businesses need cybersecurity strategies that deal with critical threats. But how can you implement an effective strategy with a small business budget?

SMBs lack the resources of corporations. But cybersecurity for small businesses must still protect sensitive data and network resources. Here are some best practices to follow that balance cost and efficiency.

1. Implement a strong password policy

Employees should only use strong passwords to log into your company network. Weak passwords are easy to guess or brute force. This makes mounting attacks much simpler.

Require employees to use 10-15 character passwords. Demand a mixture of upper and lower case letters, numbers, and symbols. Enterprise-wide password management tools can help. They make storing and changing passwords easier, eliminating much of the risk of human error.

Combining password hygiene with anti-virus software and firewall protection is also good practice. That way, you can filter potential threats and authenticate users effectively.

2. Schedule regular backups

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

3. Train employees in cybersecurity basics

Digital cybersecurity controls rely upon human knowledge and behavior. The way employees act when encountering cyber threats is a crucial part of 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 training employees to spot phishing emails and malicious links. They must know the company password and access management policies. Remote workers should also understand how to connect securely, as well as the risks of using an insecure public wi-fi network.

4. Use threat prevention measures to reduce cyber attack risks

Minimize cyber security risks by adding antivirus software and malware scanning tools to your network traffic. Use VPNs to encrypt data and anonymize user IP addresses. Create allowlists to screen user identities, admitting only authorized addresses.

Take action to secure your local network as well. You may need to upgrade your wifi network from WEP to WPA2. Check that your router SSID is anonymized and consider upgrading your firewall to add features like Deep Packet Inspection.

5. Implement protection for sensitive information

Encrypt high-value data like 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 in their working tasks. That way, when a data breach occurs, attackers will struggle to access and extract data.

Minimize the number of users with administrative privileges. Avoid giving single users the power 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. If you handle high-risk, high-value data, DLP could be a sound investment.

6. Create an Incident Response Plan

Small businesses must prepare for cybersecurity incidents. Aim to restore normal working conditions as soon as possible while protecting data and neutralizing active threats.

Carry out a risk assessment for the threats detailed above. Include an assessment of where critical data resides. Assign an individual with the responsibility to protect important data. And connect every resource with risk-reduction strategies.

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

SMBs need to be ready to act as soon as possible when cybersecurity issues arise. Be proactive and make sure everyone is aware of incident response procedures.

7. Focus on secure remote access

Many small businesses allow employees to work from home. Sales representatives may also travel widely but require access to central resources. In both cases, remote access creates cybersecurity risks.

Require strong passwords and MFA for remote connections. Consider requiring employees to use an approved VPN service when working from home. Staff may store confidential information on smartphones, creating additional risk. Enforce strict data protection policies for mobile devices.

Make sure your cyber security tools cover both on-premises and cloud resources. Remote workers can bypass central network routers if they connect to SaaS apps. This can create security gaps and compromise visibility.

8. Manage third parties securely

Small businesses rely on third-party vendors, but partners can act as 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 if you aren’t sure.

9. Enable 2FA or MFA

Small companies need to secure the network edge with robust authentication procedures. 2-factor authentication or multi-factor authentication are the best options here. These tools request 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 only for administrator accounts. Or try user-friendly 2FA procedures such as fingerprint scanning. Balance user experience and security. But always go beyond simple password protection.

Ensure your company’s sensitive information is protected

Data protection is the most important cybersecurity goal for small businesses. Data losses lead to huge reputational damage and regulatory penalties. It’s critically important to secure data and show evidence that confidential information is protected. Basic data protection measures include:

• Encrypting important databases

• Filtering access with privileges management

• Strengthening malware and firewall protection.

• Using Data Loss Prevention tools

• Educating employees about data security policies.

Beyond those actions, it’s also a good idea to check your data security posture. The Cybersecurity & Infrastructure Security Agency (CISA) provides a free “cyber hygiene” check. This is a good starting point. It should help you find vulnerabilities and identify areas of improvement.

Penetration testing also mimics the activities of hackers, providing a good measure of your data security setup. Robust testing will dramatically reduce the risk of data breaches in the future.
