Reply < 4 hServer Hardening & Security
A default Linux install leaves dozens of doors open: services you don’t use, logins you don’t need, settings meant for convenience rather than safety. Hardening closes them systematically, and gives you a written baseline your server is kept to from then on.

Unused services removed

Default-deny firewall
Fail2ban on exposed services
Web server security headers

How it works
Baseline auditCurrent configuration compared with CIS benchmarks and OWASP recommendations.
OS layerKernel parameters, service minimisation and system-level access controls applied.
Network layerFirewall rules, SSH restrictions and network parameters hardened.
Application layerWeb server, PHP and database settings tightened without breaking your apps.
Access and authenticationAccounts, sudo rules and SSH keys reviewed; two-factor where it fits.
DocumentThe full baseline is written down for future audits and compliance.
