Network Security - Moving Target Defense (MTD)

Moving Target Defense continuously changes system properties to confuse attackers.

What changes

• IP addresses

• Port numbers

• Network routes

• Software versions

Why it works

Attackers rely on static targets. MTD makes reconnaissance data useless.

Benefits

• Reduces attack success rate

• Increases attack cost

• Slows down attackers

Example

A server’s IP address changes periodically, so scanned information becomes invalid quickly.
