HIDS

Host-based Intrusion Detection System

In plain language

Software on a computer that watches for signs it has been attacked and raises an alert.

The metaphor

Like a smoke detector in one room: it watches only that room and sounds when something starts to burn.

Going deeper

How it works

  • It watches system files, logins and running programs.
  • It sees activity that a device on the network cannot, such as what happens inside a single computer.
  • It raises an alert and leaves the response to a person or other tool.
  • Most modern endpoint protection includes this function.

How WILDCARD handles it

Workstation Defender watches each protected computer around the clock.

In practice
  • An alert shows a program tried to change system settings.
  • A report lists files changed overnight.
  • An audit asks whether computers have monitoring installed.

A question owners ask

Does it stop an attack?

No. It tells you about one. The version that blocks is the prevention kind.
