QoS Definition

QoS – or “Quality of Service” – is the act of allocating and managing network resources in a way that ensures the security-related aspects of data and services receive appropriate priority and protection. In practice, it checks and manages the flow of data and services to make sure that security-critical processes are given special attention.

Consider a network that handles both regular internet traffic and encrypted communications for sensitive transactions. QoS ensures that the encrypted communication traffic, which contains sensitive data like financial transactions or personal information, gets higher priority over regular browsing traffic. In prioritizing sensitive information, QoS better protects it from potential cyber threats, ensuring that security measures such as encryption and authentication receive the necessary resources to function effectively.

In essence, QoS is the gatekeeper that ensures security processes, such as firewalls, intrusion detection systems, and encryption mechanisms, get the necessary resources and attention to safeguard against cyberattacks and unauthorized access. It’s a crucial element of maintaining a safe and secure digital environment.
