Palo Alto Networks firewall log monitoring
Firewalls provide a layer of security to all networks, and are among an organization's first few lines of defense. Over the years, they have evolved to include application firewall and intrusion prevention capabilities, in addition to traditional firewall functionalities. These "next generation firewalls" are manufactured by Palo Alto Networks, among other companies. They contain a wealth of security information, and auditing them can prove to be greatly useful for network security.
Audit data is valuable in many situations, including when:
- Numerous failed attempts to access the network occur from a single source, which may reflect malicious intent.
- A user is found to have numerous failed logons to the firewall, which could indicate an insider threat or a compromised account.
- A host receives an unusually high amount of traffic over a particular time period, causing suspicion.
- The firewall registers a string of critical events, indicating some sort of error or failure that needs to be corrected.
- A spyware download is detected, which can indicate a threat to the network.
The need for an automatic auditing process
Given that they handle traffic for the entire network, firewalls produce a significant amount of log data. With a massive amount of firewall logs, automating audit data analysis is essential. Automation eliminates the risk of missing something relevant and makes the whole process much more efficient. With its predefined reports and alerts, EventLog Analyzer is the perfect firewall auditing tool.

Palo Alto Networks log analysis reports
EventLog Analyzer's Palo Alto Networks firewall reports are classified into five groups for ease of access:
- Reports on successful logons: These reports list all the successful logons to the firewall, the hosts and users with the most number of logons, and also provide a report identifying the trend in logon patterns. Read more
- Reports on failed logons: Similar to successful logon reports, these reports list all failed logon attempts to the firewall, the hosts and users with the most number of failed logons, and also provide a report identifying the trend in failed logon patterns. Read more
- Reports on allowed traffic: These reports detail all the connections that pass through the firewall into the network, and also identify traffic patterns and trends. Read more
- Reports on denied connections: Similar to allowed traffic reports, these reports detail all the connections that are denied access to the network, and provide traffic patterns and trends as well. Read more
- System events reports: These reports identify all packages installed or upgraded on the firewall. Read more
- IDS/IPS reports: These reports list the possible and critical attacks, and identify the source and destination devices most frequently involved in attack attempts. An attack trend report is included too. Read more
- Threat reports: These reports detail various attack types, such as URL filtering, flood attacks, spyware downloads, and more, which are useful in protecting the network from breach attempts. Read more
- Severity reports: These reports classify log information by severity, and are useful for accessing all events (including emergency, error, critical, alert, warning, notice, information, and debug events) in a single click.
With a quick setup and efficient reports and alerts, EventLog Analyzer is the ideal tool for managing and analyzing Palo Alto Networks firewall logs.
