SERVER & CLOUD SECURITY
For this assignment, I had to harden a Linux server. My chosen server was Ubuntu and using Kali Linux as my client machine.
My server consist of several security elements such as encryption, account management, SSH, firewall, intrusion detection system (IDS) and intrusion prevention system (IPS).
To make SSH login secure, I implemented public and private key authentication and changed the default port number. Root login is also disabled.
For firewall, only traffic from specific ports are allowed and ping request is disabled.
I used Fail2Ban as my IPS.
Ossec is my IDS and alerts will be sent to my email.
