Which DSAC domain focuses on securing networks and communications?

• A. Network Security
• B. Governance
• C. Access Control
• D. Incident Response

Answer: (A)

Protecting the pathways that data travels and the devices that carry it is essential for keeping information confidential, integral, and available. The network security domain is the part of DSAC that concentrates on defending the networks and the communications that flow across them. It covers securing network infrastructure, configuring protections like firewalls and intrusion detection systems, ensuring encryption for data in transit (such as TLS for web traffic and VPNs for remote access), and implementing network segmentation and secure wireless practices. This focus on preventing unauthorized access, eavesdropping, and disruption of network services is what makes network security the best fit for securing networks and communications. Governance deals with policies and oversight, access control governs who can access resources and what they can do, and incident response centers on detecting and reacting to security events, so they don’t address the core task of protecting the network and its communications themselves.
