Firewalls are included in any organization’s defense-in-depth strategy. They effectively play a crucial part in guarding the network against unwanted intruders.

A firewall keeps track of all traffic entering and leaving the network and guards against malicious activity. It is a network security method that keeps track of both inbound and outbound traffic using some pre-established criteria. It keeps logs that contain data on how it controls the traffic. The traffic’s source and destination IP addresses, port information, protocols, and other information are all included in the log data. It’s crucial that users gather and examine these firewall logs if they want to defend the network from security assaults effectively.

What is firewall logging?

The method by which a log file is created for every action that goes through the firewall is known as firewall logging. The log file of activities contains everything from unsuccessful attempts to connect to the network to successful connections and everything in between. Firewall logging serves as a record of events in a situation where a problem arises and requires further investigation.

Since they can provide light on what is occurring on the network, firewall logs are significant. Anyone can utilize the logs to monitor activity, look into possible security intrusions, or keep an eye on what’s going on with their firewall if they know how to access and analyze them. Furthermore, it’s crucial to keep the records in a secure area in case investigators ever need to access them.

How and when to use firewall logging?

Significance of firewall logs

Firewall logs are important, and knowing when and how to use them is essential for network security monitoring. Here are a few situations in which firewall logging is beneficial.

  1. Analyzing network traffic and detecting unwanted activities.

A firewall log’s main purpose is to give information about network traffic. This contains details about the type of outgoing and inbound traffic as well as cyber risk attempts at the network’s edge, based on which corrective measures can be taken. The information in firewall logs also covers malicious actions taking place on the network. However, the limited data that the firewall logs offer makes it impossible to pinpoint the origin of the activity.

  1. Evaluating the firewall rules that are recently added

A firewall rule either permits or forbids traffic to or from a certain IP address. However, securing the network only by implementing firewall rules is insufficient. A logging function should be added to these rules so that users can evaluate whether they are operating well and whether any rule changes are authorized.

  1. Planning for bandwidth requirements

The bandwidth need can be planned based on data on bandwidth usage throughout the firewall.

  1. Adding harmful sources on a blacklist

Threat intelligence gives details on well-known bad actors. Users can find known malicious IPs by using the threat feeds from sites. They can identify any attempts for access from such an IP address and immediately stop it using a firewall rule by activating logging and monitoring firewall logs.

Additionally, it may be a security risk if numerous unsuccessful attempts to reach the firewall or any other high-profile device inside the network originate from a single IP address. The logs can be carefully examined, and a new rule can be created to blacklist that IP.
