Description: Network Access Control (NAC) is a security solution that enforces policies for devices accessing a network. Its primary goal is to ensure that only authorized and secure devices can connect to the network, thereby protecting the infrastructure from potential threats. NAC evaluates the security status of devices, such as the presence of updated antivirus software, security patches, and proper configurations. If a device does not meet established policies, NAC can restrict its access or redirect it to a quarantine network where it can perform necessary updates. This technology is fundamental in enterprise environments where information security is critical, as it helps prevent unauthorized access and mitigate risks associated with compromised devices. Additionally, NAC can integrate with other security solutions, such as multifactor authentication and monitoring systems, to provide a defense-in-depth approach. In a world where remote work and the use of personal devices in the workplace are increasingly common, Network Access Control has become essential for maintaining the integrity and confidentiality of data across various organizational settings.
