Network access control (NAC) is a security solution that gives administrators control over which users, devices and applications can access a given network. It works by using an authentication process to identify, authenticate and authorize users, devices and applications before granting access to the network. At its core, NAC is a policy-enforcement system that uses policies to ensure that each user, device or application that connects to the network meets certain security requirements. To provide this access control, NAC solutions typically use various technologies, such as 802.1X, RADIUS, VPNs and Network Access Control Lists (ACLs). In addition to providing access control, it is also possible to incorporate other security layers, such as anti-malware, data

A mail enabled security group is a type of Active Directory group which can receive emails sent to its members. It is used to manage distribution lists, similar to a Contact Group in Microsoft Exchange. It also supports the ability to add members both from inside and outside of an organization’s domain.

Cybersecurity has changed drastically over the years, with ever more sophisticated approaches being needed to stay ahead of attackers. In the early days, security focused on basic antivirus protection, basic firewalls, and static perimeter defense. But now, the focus is shifting to areas like machine learning, artificial intelligence, and predictive analytics, which can detect and mitigate threats much more quickly and accurately. Furthermore, new technologies such as blockchain, which provide a secure distributed ledger, are also providing additional layers of protection. As the threats to digital and online systems become more complex, cyber security needs to evolve and adapt in order to keep up.
