What is a primary purpose of network controls?

The primary purpose of network controls is to ensure information security during communication. These controls are essential in protecting the confidentiality, integrity, and availability of information as it traverses networks. By implementing various network controls, such as firewalls, intrusion detection systems, and encryption protocols, organizations can safeguard sensitive data from unauthorized access or breaches while ensuring that communications are secure.

Effective network controls also facilitate compliance with various regulatory requirements and protect against a range of cybersecurity threats, including malware and data interception. This focus on securing communication aligns with the broader objectives of information security management systems, such as those outlined in ISO 27001, which emphasize the protection of information assets throughout all forms of transmission.

In contrast, while faster internet access is beneficial, it is not the primary goal of network controls; their aim is specifically directed towards security. Monitoring employee internet usage is typically linked to policy enforcement and productivity rather than security. The integration of new technologies, though important, is secondary to the fundamental objective of maintaining security during data transmission.
