Voice intrusion prevention system
(also VIPS)
Voice intrusion prevention system definition
A voice intrusion prevention system (VIPS) is a technology that protects voice communication systems from unauthorized access, misuse, and security threats. Voice communication systems include mobile phones, voice messaging, and landline telephones.
VIPS acts as a security system for voice calls, similar to how antivirus software protects computers from malware. It detects and prevents unauthorized or suspicious activities in voice networks, such as unauthorized call interceptions, eavesdropping, tampering, or fraudulent activities.
VIPS helps maintain the security and privacy of voice communications, ensuring that sensitive information exchanged during phone calls remains protected.

How voice intrusion prevention systems work
Voice intrusion prevention systems (VIPS) employ various techniques to detect and prevent unauthorized access or malicious activities in voice communication networks. Here’s how:
- Traffic monitoring. VIPS monitors voice network traffic, checking the information in packets to see if anything important or concerning is happening.
- Signature-based detection. VIPS spots security threats related to voice calls by comparing them to known patterns or signs of trouble. When it finds a match, it sends an alert to warn of the problem.
- Anomaly detection. VIPS watches for unusual or unexpected behavior by studying how voice calls usually happen. If something deviates too much from the norm, it raises a flag to indicate a possible security threat or unauthorized activity.
- Voice activity analysis. Voice activity analysis: VIPS studies the characteristics of voices to find any interactions or speech patterns that shouldn’t be there. It can even do this when the voices are encrypted or compressed, helping to identify suspicious activity.
- Policy enforcement. VIPS makes sure that everyone follows the rules by enforcing security policies. It monitors how voice calls are used, routed, and controlled to ensure they meet the established guidelines.
- Real-time alerting and response. VIPS promptly sends alerts if it detects something that could be a threat or violation. These alerts provide immediate information so security personnel can quickly respond and take automated actions to address the issue.
