What Does Fraud over Internet Protocol Mean?

Fraud over Internet Protocol (FoIP) is the criminal act of stealing network capacity while undermining Voice over Internet Protocol (VoIP) device vulnerabilities.

The term was coined in 2006 after two men were arrested for hacking an unprotected corporate IP network and the networks of several VoIP providers. The hackers then rerouted the organization's network traffic to VoIP providers, resulting in call terminations and hefty interconnect charges for providers.

Techopedia Explains Fraud over Internet Protocol

FoIP can be prevented by adhering to the following security practices:

  • Basic security measures, such as firewall port protection
  • During repairs or upgrades, technicians should not allow open ports to remain open for extended periods. Otherwise, a system becomes an easy FoIP target.
