I will secure and harden your linux vps server, ssh, and firewall

Is your Linux VPS running with default, vulnerable settings?

Public servers face automated scans for exposed SSH ports, weak passwords, and missing firewalls. I will audit, lock down, and harden your Linux server to CIS Benchmark standards with zero downtime.

What I will do for your server:

1. SSH & Access Lockdown:

- Enforce Ed25519/RSA SSH Key-only authentication

- Disable root login & password authentication

- Limit brute-force tries & connection grace periods

2. Firewall & Network Defense:

- Configure strict UFW / Iptables rules (Default DENY incoming)

- Expose only required service ports (HTTP/HTTPS/SSH)

3. Intrusion Prevention & Automation:

- Setup Fail2Ban / Auto-drop rate limiting to ban malicious IPs

- Enable automated security updates for core packages

4. System Hardening & Audit:

- Secure shared memory (/dev/shm) mount flags (noexec, nosuid)

- Deliver a before/after audit verification report

Supported OS: Ubuntu, Debian, CentOS, AlmaLinux, Rocky Linux on AWS, DigitalOcean, Hetzner, Vultr, Linode, or private VMs.
