5 Firewall Configurations to Better Defend Your Network Against Ransomware

Ransomware attacks have actually taken on one of the most destructive forms of cybercrime that companies have to deal with, and they continue to evolve at a rapid pace in our current day-in-age. There is a growing urgency for strong and fluid defense mechanisms to protect against system compromise. Firewall is one of the main components of any cybersecurity strategy. The first line of defense provided by a properly configured firewall will block potential threats before they enter the network. This discussion will focus on how five essential firewall configuration changes can help further protect your network against ransomware attacks and why businesses should consider using firewall rentals.

1. Segmentation and Zoning

Example and Recommendation:
A best practice of your network is to divide it up into smaller, less controlled zones in order to contain the spread of malware. Organize your internal networks into zones by roles as administrative, accountancy and guest networks. This can be segmented so if a ransomware attack does breach one zone, it won’t immediately jump to other parts of the network easily.

Actionable Tip:
Drive policy based execution for each zone by segmenting the traffic using VLANs (Virtual Local Area Networks) across your network. Configure your firewall to track and manage the flow of data between these segments.

2. Intrusion Prevention Systems — IPS

Example Best Practices
Intrusion Prevention Systems detect suspicious activities while it happens in real-time to prevent the exploitation that will be conducted by ransomware. IPS blocks the malicious traffic to avoid known exploits on this layer so that it can be automatically stopped before reaching your system.

Actionable Tip:
Make sure you have an IPS (intrusion prevention system) in your firewall. This way, the IPS can regularly fetch its signature databases to keep track of up-to-date threats so it blocks new emerging dangers at the intended level of sophistication.

By implementing granular access controls, you can track who is accessing different parts of your network with one simple logging system—they also help to diminish the ease that an insider threat or outside vulnerability will be exploited.

Actionable Tip:
By the same point of your firewall to support strong authentication mechanisms, such as multi-factor authentications. Create access rules that restrict your network privileges to the minimum required for specific user roles.

4. Application-Level Filtering

Ex: Best Practices
Application-level layer of inspection is an ideal solution that takes network traffic a step further, where this analysis now reaches into the data packets themselves via individual applications. Disconnect all networks — a ransomware infection path is to avoid being laughed at as you can help, blocking potentially dangerous applications from contacting out to the internet.

Actionable Tip:
Continuously install and update application filters in your firewall configuration. Periodically check what applications are allowed to talk to your systems and block anything where vulnerabilities have been found.

Actionable Tip:
Make sure that your firewall is logging all incoming and outgoing traffic. Leverage this intelligence to detect abnormal behaviors and potential threats in the making.
