What Microsoft technology verifies that a client has the latest Windows updates and an updated antivirus before granting network access?

Network Access Protection (NAP) is the Microsoft technology designed to ensure that a client device meets specific security requirements, such as having the most recent Windows updates and a current antivirus solution, before permitting it to access the network. This mechanism plays a crucial role in maintaining the overall security posture of a network by enforcing compliance standards.

When a client attempts to connect to a network, NAP evaluates various factors, including the state of the client's security software and update status. If the device does not comply with the necessary security requirements, access to the network can be restricted, or the user may be redirected to remediation resources to bring their device into compliance.

This proactive approach is essential for preventing systems that are vulnerable due to outdated software from spreading malware or being exploited. By integrating compliance checks into the access control process, NAP helps to protect the entire network from potential threats that could arise from non-compliant devices.

Other technologies mentioned, such as Active Directory, provide identity and access management but do not specifically address endpoint security compliance. Windows Defender focuses on antivirus capabilities and real-time threat protection but does not handle network access. Azure Security Center offers security management for cloud resources but is not solely focused on verifying client compliance for network access. Therefore, NAP is
