Firewalls provide visibility into the source and type of network traffic entering an organization's network, which makes firewall logs an important source of information, including details such as the source address, destination address, protocol, and port number of all connections, which can provide insight into Insights into unknown security threats are an important tool in threat management.
How Firewall Logging Works
Firewall logs contain information about events such as:
- event type
- Source and destination IP addresses
- The port number
- protocol
- timestamp
- action
- Rule ID
Firewall logs are analyzed and analyzed by a firewall analyzer or log management solution to identify patterns or anomalies to detect attacks and generate reports. Analyze information contained in firewall logs to provide insights into network traffic patterns, security events, and connection statistics.
How Monitoring Firewall Logs Can Help Protect Your Network
By monitoring firewall logs, you can gain insight into network activity and potential security threats. It helps to:
- Network Visibility : Firewall logs provide insights into network traffic and activity, which helps to identify trends and any abnormal behavior within the network, enhanced network visibility helps to take proactive security management measures.
- Threat Detection : Analyzing firewall logs helps organizations detect any suspicious activity, port scans, unauthorized access attempts, or any unusual traffic patterns that might indicate an attack. By analyzing these logs, suspicious behavior can be detected in real time, which helps organizations take immediate action to reduce risk and prevent security incidents.
- Intrusion Detection : Firewall logs can be used to detect network intrusions. Analyzing logs for indicators of intrusion or known attack techniques can help identify potential threats and reduce unauthorized access attempts.
- Incident Response : Firewall logs provide valuable insight into security incidents. This helps IT security teams understand the nature, scope and impact of incidents to facilitate incident response.
- Compliance : Firewall logs help organizations demonstrate compliance with compliance requirements and regulations, as well as industry-specific security requirements.
How to Automatically Monitor Firewall Logs
When Firewall Log Analyzer automatically monitors and analyzes logs, it helps to detect threats in real-time and take immediate action to minimize the impact of the incident. Automation of firewall log monitoring can be achieved with a firewall log management solution such as EventLog Analyzer. The solution correlates suspicious events and immediately mitigates threats using automated workflows.
Firewall Audit
EventLog Analyzer is a log management solution that collects logs from firewall devices and organizes them in one place. This solution is also a firewall auditing tool that enables security administrators to easily monitor firewall logs, perform firewall analysis and detect anomalies, using correlation and real-time alerts to proactively detect and mitigate potential threats.
- Login Audit
- Configuration Change Auditing
- User Account Change Auditing
- Firewall traffic monitoring
- incident response
Login Audit
The solution provides insights into successful and failed user logins in the form of analytical reports that include information on the source of login events, when they occurred, and more. Events are continuously monitored to identify login patterns and serve as detections that may indicate an attack or insider threat Baseline for suspicious login attempts.
Configuration Change Auditing
EventLog Analyzer analyzes firewall log data and provides insights into configuration changes and misconfigurations. The tool provides details such as who made configuration changes, when and from where, which not only helps in effective auditing, but also helps in compliance with regulatory requirements such as PCI DSS, HIPAA, FISMA, etc., which Enterprises are required to audit firewall configuration changes.
User Account Change Auditing
These reports provide insights into user additions, modifications, deactivations or deletions, and user privilege level changes, thereby providing visibility into user account activity, using this information to detect any suspicious or unusual user account activity, and to identify any insider threats or Privilege escalation attempt.
Firewall traffic monitoring
EventLog Analyzer provides traffic information from allowed and denied connections, these reports provide detailed information categorized and visually represent traffic based on source, destination, protocol and port, and time stamp, enabling security administrators to track network traffic. This helps identify unusual traffic trends from suspicious sources and prevent threat actors from gaining access to the network.
incident response
An effective event detection process is provided through event correlation, and security threats in firewall events can be detected with the help of built-in correlation rules. Instant alerts are sent to security administrators when any suspicious activity is detected, which helps to speed up the response process, alerting administrators to possible threats at an early stage so that they can effectively protect the organization's network from significant damage.
