Ensure Online Certificate Status Protocol (OCSP) stapling is enabled

SrednjaNivo 1Automatskanginx

Opis

OCSP stapling allows a server to efficiently deliver certificate revocation information to the client, improving performance and privacy. The server caches the OCSP response from the Certificate Authority (CA), eliminating the need for the client to make a separate connection. All four directives must be present: ssl_stapling on, ssl_stapling_verify on, ssl_trusted_certificate and resolver. 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.

Kako se proverava

Metod provere: Komanda ljuske

shell

out=$(nginx -T 2>/dev/null) || exit 1; printf '%s\n' "$out" | awk '{l=$0; o=""; q=""; for(i=1;i<=length(l);i++){c=substr(l,i,1); if(q!=""){o=o c; if(c==q) q=""; continue} if(c=="\""||c=="\047"){q=c; o=o c; continue} if(c=="#") break; if(c==";"||c=="{"){print o c; o=""; continue} if(c=="}"){if(o~/[^[:space:]]/) print o; print "}"; o=""; continue} o=o c} if(o~/[^[:space:]]/) print o}' | awk 'function a(i,  x){x=$i; sub(/;$/,"",x); gsub(/["\047]/,"",x); return x} function inb(n,  i){for(i=1;i<=sp;i++) if(st[i]==n) return 1; return 0} $1=="ssl_stapling" && a(2)=="on"{s=1} $1=="ssl_stapling_verify" && a(2)=="on"{v=1} $1=="ssl_trusted_certificate"{t=1} $1=="resolver"{r=1} {o=gsub(/\{/,"{"); c=gsub(/\}/,"}"); while(o-->0){sp++; b=$1; sub(/\{.*/,"",b); st[sp]=b} while(c-->0 && sp>0) sp--} END{print (s&&v&&t&&r)?"compliant":"noncompliant"}'

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

Add 'ssl_stapling on; ssl_stapling_verify on; ssl_trusted_certificate /etc/nginx/ssl/chain.pem; resolver <dns ip>;' to the HTTPS server blocks. Then run nginx -t and reload nginx.
