Ubuntu Security

A very basic overview of tools and methods to secure your server. Really just for ourselves for future reference.

Security Audit

Identify services running locally

sudo netstat -plunt

Scan for open ports on another host

  1. Install nmap: sudo apt-get install nmap
  2. Scan for every TCP and UDP open port:
    sudo nmap -n -PN -sT -sU -p- remote_host
  3. See what service is running on a port:
    sudo nmap -PN -p port_number -sV remote_host
