What is the main goal of network security measures?

The main goal of network security measures is to protect network data from unauthorized access and threats. This involves implementing various strategies, techniques, and tools designed to safeguard sensitive information and maintain the integrity, confidentiality, and availability of data as it travels through networks.

Network security encompasses a wide array of practices, including the use of firewalls, intrusion detection systems, encryption, and access controls, all aimed at defending against cyber threats such as malware, phishing attacks, unauthorized access, and data breaches. Ensuring that only authorized users can access specific network resources helps to maintain a secure environment and protects sensitive information from cybercriminals.

Other options may focus on different aspects of network management or optimization, but they do not emphasize the central concern of safeguarding data. Increasing the speed of network connections, reducing costs, or simplifying configurations are important, yet they are secondary to the primary goal of maintaining security within the network infrastructure.
