Ports

KNOW WHAT THE HACKERS KNOW

• Random Unix ports are often not random.
• BSD Unix based systems often reserve ports below 1024 for privileged processes.
• System V Unix TCP/IP networking draws heavily from BSD.
• Many vulnerable services, such as X-windows and a few database servers, use server ports at or above 1024.

Notes:

Hackers probably know the system internals better than your own staff.
