Small Business Firewall Management Tool Tips

Small businesses like yours confront cybersecurity threats every day that jeopardize your networks and confidential data. Implementing firewall management tools and following best practices is a great starting point for protecting your sensitive data. 

By implementing firewall management tools, you can safeguard network traffic, monitor access to resources, and prevent unauthorized users or devices from gaining access. But just implementing the first firewall management tool you encounter isn’t enough. In this article, we’ll explain five best practices for firewall management, empowering small businesses like yours with the information you need to enhance your network security.

What is a Firewall?

Cisco defines a firewall “as a network security device that monitors traffic to or from your network. It allows or blocks traffic based on a defined set of security rules.” Network firewalls act as guardians, protecting against unauthorized network access and cyber threats. These systems filter and scrutinize incoming and outgoing traffic. Because firewall management tools are so important to protecting private information, many industries must implement firewalls to comply with regulatory mandates.

Five Best Practices For Firewall Management Tools

You will need vigilant monitoring, configuring, and administering to effectively manage your firewall tools and ensure network protection against security threats. If your business is complex enough to need multiple firewalls, you’ll want to consider leveraging firewall security management (FSM) software, which centrally monitors and governs firewalls, routers, load balancers, and switches, ensuring comprehensive network protection. 

One essential aspect of firewall management is leveraging firewall management tools effectively. These tools play a vital role in monitoring and securing network traffic, ensuring that only authorized access is granted to resources. However, a firewall management tool on its own will not be enough; you’ll also need to understand and implement firewall best practices. By following these five best practices, your small business can proactively mitigate risks.

1: Properly Configure and Harden Your Firewall

Firewalls filter network traffic based on predefined rules, allowing safe communication while blocking unauthorized access. You should have your firewall management tools configured and reviewed by knowledgeable professionals. 

Hardening your firewall management tool maximizes security. While web servers or email servers are commonly hardened, other systems like file servers or workstations may not usually receive the same level of attention. Hardening systems like Red Hat or FreeBSD, are often easier and more effective to secure than some other options, like Windows servers. 

To harden a Windows server, you’ll need to disable unnecessary services, remove redundant registry entries, and apply stringent permissions. This proactive approach reduces vulnerabilities and minimizes the need for frequent patches, enhancing overall security.

2: Use Zero Trust Security

Zero trust security emphasizes distrust of all users and devices by default. This approach prioritizes authentication, and each request is viewed as potentially originating from an untrusted source, blurring the distinction between internal and external threats to bolster security. Adhering to zero-trust firewall policies ensures that users and devices are granted only essential access. 

This means that even if there is an attack, it would be contained and wouldn’t be able to spread. Leveraging firewall management tools is crucial for implementing and monitoring zero-trust firewall policies effectively. These tools enable continuous monitoring of firewall activity, ensuring adherence to the principles of zero-trust network security.

3: Secure Your Firewall

Even with all the benefits of firewalls and firewall management tools, they are not immune to vulnerabilities and need to be protected. There are some easy steps you can take to secure your firewall.

Steps to Secure Your Firewall:

  • Disabling Insecure Protocols: Identify and deactivate any outdated or insecure protocols running on the firewall. By disabling these protocols, you minimize potential vulnerabilities and enhance the overall security posture of your firewall.
  • Scheduling Backups: Implement a regular backup schedule for firewall configurations and system data. Scheduled backups ensure that you have up-to-date copies of critical configurations and settings, which can be crucial for restoring the firewall in the event of a system failure or security breach.
  • Enabling Auditing: Activate the auditing features on your firewall to monitor and track system activities, configuration changes, and security events. By enabling auditing, you can proactively identify and respond to potential security threats, strengthening your overall cybersecurity defenses.
  • Adding Stealth Rules: Implement stealth rules in the firewall configuration to conceal the presence of network services and minimize exposure to potential attackers. Stealth rules block inbound traffic to unused or unnecessary ports, reducing the firewall’s visibility to external scans and malicious actors. 
  • Regular Software Updates and Patch Management: Establish a process for regularly updating firewall software and applying security patches. By staying current with software updates, you can ensure that your firewall remains resilient against emerging threats and exploitation attempts, reducing the likelihood of successful cyberattacks.
  • Conduct Regular Cybersecurity Risk Assessments:  A cybersecurity risk assessment is a look at how well an organization can protect its data and information systems from cyber threats. Once vulnerabilities are identified, develop a remediation plan to address them promptly, whether through software updates, configuration changes, or additional security controls.

4: Secure User Accounts

Account takeovers (ATOs) pose a significant threat to small businesses’ online security, occurring when cybercriminals gain unauthorized access to business, user, or employee accounts, resulting in potential fraud, financial loss, and damage to reputation. To mitigate this risk, consider the following measures:

  • User Authentication and Authorization: Implement authentication and authorization policies for network access. Regularly update users to remove unnecessary access.
  • Employee Training Programs: Educate employees on recognizing phishing attacks through regular and comprehensive training. Employee awareness is crucial, as they are often the weakest link in the security chain.
  • Multi-Factor Authentication (MFA): Implement MFA to add an extra layer of protection, requiring users to provide additional authentication factors alongside credentials, significantly reducing the likelihood of a successful ATO.
  • Password Policy: Establish a password policy outlining criteria such as minimum character length, use of special characters, punctuation, and numerical characters.

5: Lock Down Zone Access to Approved Traffic

When setting up your firewall, establish connections between its network interfaces and different zones to streamline firewall policy management. For example, a perimeter firewall typically links to the Internet (external zone) and internal networks (internal zone). Network segmentation mitigates cyber risks by partitioning networks into zones and deploying security solutions at zone boundaries.  Firewalls can enforce segmentation policies, which rely on real-time insights into application communication. 

Firewall rules govern traffic flow in and out of a network based on criteria like source/destination IP, ports, and protocol. These rules, integral to firewall policies, thwart unauthorized traffic and malicious programs, safeguarding network security. Effective firewall rule management is indispensable for maintaining a robust network security infrastructure. Leveraging firewall management tools to monitor firewall activity ensures ongoing protection against emerging threats.

Safeguarding Networks Against Cyber Threats

Firewall management tools are important for small businesses like yours that are looking to bolster their network security defenses. By following best practices such as disabling insecure protocols, scheduling regular backups, enabling auditing, adding stealth rules, and implementing software updates and patches, you can proactively safeguard your networks against cyber threats. Regular monitoring of firewall activity and configurations is essential to ensure ongoing protection and identify any potential vulnerabilities or security incidents promptly.
