About this Gig

Is your server really secure? Many servers have open ports, weak SSH settings, old software or default configurations that attackers scan for every day.


I am a systems administration student (ASIR) focused on security. I will check your server the way an attacker would look at it from outside, and the way an admin checks it from inside, then give you a clear report in plain English.


What I check:

- Open ports and exposed services (Nmap)

- SSH, firewall, users, sudo and password policy

- Outdated packages and insecure TLS settings

- Linux hardening with Lynis and CIS recommendations

- Windows Server: firewall, updates, local admins, RDP, password and lockout policy

- Active Directory: privileged groups, inactive and never-expiring accounts, GPOs and share permissions


What you get:

- PDF report with risks sorted by priority (High, Medium, Low)

- Step by step fixes for each issue

- Premium: I apply the fixes and confirm them with a new scan


I only work on systems you own or are authorized to test. Please message me before ordering.
