What are the five essential features of network service security?

Critical features like firewalls and encryption are essential for establishing strong and effective network service security. Firewalls act as a barrier between a trusted internal network and untrusted external networks, controlling incoming and outgoing network traffic based on predetermined security rules. Encryption, on the other hand, involves encoding information in a way that only authorized parties can access and understand it. These features help protect against unauthorized access, data breaches, and other security threats, ensuring the confidentiality, integrity, and availability of network services.
