What is a key task that network security needs to perform?

Securing end user devices is a key task for network security because these devices are often the primary access point for potential threats and vulnerabilities within a network. With the increase in remote work and mobile device usage, ensuring that end user devices are secure is essential for protecting sensitive data and maintaining the integrity of the overall network. This involves implementing measures such as endpoint protection, encryption, and access controls to mitigate risks associated with malware, data breaches, and unauthorized access.

While providing support for end users, training for IT staff, and updating software are important tasks within an organization, they are not specifically the main focus of network security. The primary goal of network security is to create a fortified environment that safeguards all devices connected to the network from external and internal threats.
