Definition
Quality of service (QoS) is a network management tool that prioritizes the performance of more important tasks over less critical ones. For instance, video conferencing and VoIP are prioritized to ensure low-latency performance.
Examples of Quality of Service in Cybersecurity
- VoIP prioritization: QoS prioritizes VoIP communications to ensure voice calls are clear, secure, and uninterrupted, especially during high network usage.
- Security monitoring traffic: QoS can provide timely security alerts, which is crucial for security-related systems like event management (SIEM) platforms and intrusion detection systems.
- Video conferencing: QoS can prioritize video and audio data in a video conference. This prevents buffering and dropped calls, vital for secure remote meetings.
