NGNIX Config file CLI

[0777]

Hi all,

How modify nginx config in /user/local/etc/ngnix

for this adding :

add_header X-XSS-Protection "1; mode=block";
 add_header Expect-CT "enforce, max-age=300, report-uri='https://.fr/'"; server_tokens off;

Same issues for this files :

/var/etc/nginx-webConfigurator.conf

 server {
            listen 443 ssl http2;
            listen [::]:443 ssl http2;

            ssl_certificate         /var/etc/cert.crt;
            ssl_certificate_key     /var/etc/cert.key;
            ssl_session_timeout     10m;
            keepalive_timeout       70;
            ssl_session_cache       shared:SSL:10m;
            ssl_protocols   TLSv1.2 TLSv1.3;
            ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH";
            ssl_prefer_server_ciphers       on;
            add_header Strict-Transport-Security "max-age=31536000";
            add_header X-Content-Type-Options nosniff;
            ssl_session_tickets off;
            ssl_dhparam /etc/dh-parameters.4096;

Config is keep in the file config, but never updated after Webconfigurator restart.

If i try to modify in another modules the modify is deleted during restart of WebConfigurator.

Any idea ?

PS : kali linux scan (nikto) :

Thanks.
