P2P

Peer to Peer

In plain language

A way of sharing files or connecting directly between computers, with no central server in between.

The metaphor

Like neighbours swapping tools over the fence: quick, and nobody at a shop counter checks what changes hands.

Going deeper

How it works

  • Each computer both sends and receives.
  • File sharing apps and some chat and video tools use it.
  • It can expose your address and your files to strangers.
  • Downloads from unknown sources can carry malware.

What can go wrong (example scenario)

An employee installed a file-sharing program on a work laptop. The download carried a hidden program that began copying files to an outside address.

How WILDCARD handles it

Network covers firewall rules that block such traffic, and Workstation Defender watches each protected computer for malware.

In practice
  • A torrent client appears on a work laptop.
  • A video-call tool connects two computers directly.
  • A firewall report flags unusual traffic from one machine.

A question owners ask

Should staff use these programs at work?

Generally no. Business networks block them because of the legal and security risk.
