Information

Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity.

The Palo Alto Networks security platform has multiple log types; at a minimum, the Traffic, Threat, System, and Configuration logs must be sent to a Syslog server.

Solution

To create a syslog server profile:
Go to Device >> Server Profiles >> Syslog
Select 'Add'.
In the Syslog Server Profile, enter the name of the profile.
Select 'Add'.
In the 'Servers' tab, enter the required information.
Name: Name of the syslog server
Server: Server IP address where the logs will be forwarded to
Port: Default port 514
Facility: Select from the drop-down list.
Select 'OK'.

After creating the Server Profiles that define where to logs, enable log forwarding.
The way to enable forwarding depends on the log type:
Traffic Logs-Enable forwarding of Traffic logs by creating a Log Forwarding Profile (Objects >> Log Forwarding) and adding it to the security policies to trigger the log forwarding. Only traffic that matches a specific rule within the security policy will be logged and forwarded.
Configure the log-forwarding profile to select the logs to be forwarded to syslog server.
Go to Objects >> Log forwarding
The Log Forwarding Profile window appears. Note that it has five columns. In the Syslog column, select the syslog server profile for forwarding threat logs to the configured server(s).
Select 'OK'.

When the Log Forwarding Profile window disappears, the screen will show the configured log-forwarding profile.
Threat Logs-Enable forwarding of Threat logs by creating a Log Forwarding Profile (Objects >> Log Forwarding) that specifies which severity levels to forward and then adding it to the security policies, which triggers the log forwarding. A Threat log entry will only be created (and therefore forwarded) if the associated traffic matches a Security Profile (Antivirus, Anti-spyware, Vulnerability, URL Filtering, File Blocking, Data Filtering, or DoS Protection).
Configure the log-forwarding profile to select the logs to be forwarded to syslog server.
Go to Objects >> Log forwarding
The Log Forwarding Profile window appears. Note that it has five columns. In the 'Syslog' column, select the syslog server profile for forwarding threat logs to the configured server(s).
Select 'OK'.

When the Log Forwarding Profile window disappears, the screen will show the configured log-forwarding profile.
System Logs-Enable forwarding of System logs by specifying a Server Profile in the log settings configuration.
Go to Device >> Log Settings >> System Logs
The list of severity levels is displayed.
Select a Server Profile for each severity level to forward.
Select each severity level in turn; with each selection, the 'Log Systems - Setting' window will appear.
In the 'Log Systems - Setting' window, in the 'Syslog drop-down' box, select the configured Server Profile.
Select 'OK'.
Config Logs-Enable forwarding of Config logs by specifying a Server Profile in the log settings configuration.
Go to Device >> Log Settings >> Config Logs
Select the 'Edit' icon (the gear symbol in the upper-right corner of the pane).
In the 'Log Settings Config' window, in the 'Syslog drop-down' box, select the configured Server Profile.
Select 'OK'.

For Traffic Logs and Threat Logs, use the log forwarding profile in the security rules.
Go to Policies >> Security Rule
Select the rule for which the log forwarding needs to be applied.
Apply the security profiles to the rule.
Go to Actions >> Log forwarding
Select the log forwarding profile from drop-down list.
Commit changes by selecting 'Commit' in the upper-right corner of the screen. Select 'OK' when the confirmation dialog appears.
