TMA-NGINX-3.2

Ensure access logging is enabled

SrednjaNivo 1Automatskanginx

Opis

The access_log directive enables the logging of client requests. While NGINX enables this by default, it allows granular control per server or location context. Based on enterprise requirements, the log should be enriched with relevant variables or converted to structured JSON format for modern SIEM integration. Refer to Recommendation 3.1 for detailed configuration of log formats and variables. Fails when access_log off is used outside a location block (in the http or a server context); location-level exclusions for static assets are allowed. Evaluated on the merged configuration printed by `nginx -T` (all included files; needs permission to read them). CIS marks this recommendation Manual; the automated check implements its audit procedure.

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

Replace 'access_log off;' at http/server level with 'access_log /var/log/nginx/access.log <format>;'. Then run nginx -t and reload nginx.
