What is the primary purpose of network security?

The primary purpose of network security is to protect data and resources from unauthorized access. This involves implementing various measures and technologies designed to prevent intrusions, breaches, and attacks that could compromise sensitive information or disrupt network operations. These security measures include firewalls, encryption, intrusion detection systems, and authentication protocols, all aimed at creating a secure environment for data transmission and storage. By focusing on safeguarding assets and ensuring only authorized users can access critical resources, network security helps maintain the confidentiality, integrity, and availability of information within a network. This foundational principle underpins all other aspects of network management and is crucial for maintaining trust in digital communications and transactions.
