Security Event log backup with Security Monitoring

Description

If a Security Violation event is not received by the Security Monitoring module, the data representing the attack is lost.

Resolution

F5 NGINX App Protect supports logging to multiple destinations, enabling the user to send a log to NGINX agent and a copy to be stored as a backup. In the event of a failure to receive Security Events in Security Monitoring, the backup log can be checked to verify attack details. Change the settings below to enable backup logging:

1. Instance with Security Monitoring only

app_protect_policy_file "/etc/app_protect/conf/NginxDefaultPolicy.json";
app_protect_security_log_enable on;
app_protect_security_log "/etc/app_protect/conf/log_sm.json" syslog:server=127.0.0.1:514;
app_protect_security_log "/etc/app_protect/conf/log_sm.json" <Path to store log file>;
# Example: app_protect_security_log "/etc/app_protect/conf/log_sm.json" /var/log/app_protect/security.log;

1. Instance with Security Monitoring and Instance Manager

app_protect_policy_file "/etc/nms/NginxDefaultPolicy.tgz";
app_protect_security_log_enable on;
app_protect_security_log "/etc/nms/secops_dashboard.tgz" syslog:server=127.0.0.1:514;
app_protect_security_log "/etc/nms/secops_dashboard.tgz" <Path to store log file>;
# Example: app_protect_security_log "/etc/nms/secops_dashboard.tgz" /var/log/app_protect/security.log;
