Overview
What it is:
A botnet is a large group of infected, “slave” computers controlled without permission by a single “master” computer.
What it does:
Hackers use botnets to launch denial of service attacks against larger organizations, as well as sending SPAM, mining for cryptocoin and other illegal activities.
Why it matters:
Botnets can launch powerful attacks that are difficult to defend. Enterprises need to take pre-emptive steps to mitigate the potential risks of botnets.
What to do about it:
Prevent botnet infections by “hardening” systems with multi-factor authentication and high-level encryption, and look to mechanisms that can protect against a botnet attack.
