Glossary of Cyber Security Terms

Virtual Private Network (VPN)

A VPN is a specialized network configuration designed to provide a secure and encrypted connection over a less secure network, such as the internet. It simulates a private network, harnessing resources from a broader public network while protecting data via encryption and tunneling techniques. By creating encrypted links across the internet and controlling traffic through firewalls, businesses can securely connect various locations into a single network. VPNs are generally more cost-effective than dedicated private networks, as they share system resources with other users of the broader network.

Virus

In the realm of cybersecurity, a virus is a piece of malicious software that attaches itself to legitimate programs, self-replicates, and infects other files or systems. Unlike a standalone program, a virus requires its host application to run, triggering the viral code to execute. Viruses can cause a wide range of issues, from compromising system performance to causing severe data loss or breaches.

Voice Firewall

A voice firewall is a specialized security device for voice networks, which monitors, alerts, and regulates inbound and outbound network activity based on pre-determined policies. By identifying threats at the voice application layer or detecting unauthorized service use, it ensures the integrity and security of voice communications.

Voice Intrusion Prevention System (IPS)

A Voice Intrusion Prevention System proactively safeguards voice networks by monitoring voice traffic for potential threats or unusual patterns. It recognizes and mitigates risks such as toll fraud, denial of service attacks, and other forms of telecommunications threats or abuse. By preventing such anomalies, a Voice IPS contributes to the overall security and reliability of voice communication systems.
