Security controls can be classified by various criteria. For example, controls can be classified by how/when/where they act relative to a security breach (sometimes termed control types): Preventive controls are intended to prevent an incident from occurring e.g. by locking out unauthorized intruders;
The CIS Controls (formerly called the Center for Internet Security Critical Security Controls for Effective Cyber Defense) is a publication of best practice guidelines for computer security. The project was initiated early in 2008 in response to extreme data losses experienced by organizations in the US defense industrial base. [ 1 ]
Network access control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.
Standard security measures, such as firewalls, intrusion detection systems (IDSs) and antivirus software, are commonly available products that guard computers against outsider and insider attacks. [ 5 ] The use of a firewall, for example, prevents the access of outsiders to the internal network and an intrusion detection system detects ...

Network security are security controls, policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. [1] Network security involves the authorization of access to data in a network, which is controlled by the network ...
Availability controls: The best control for this is to have excellent network architecture and monitoring. The network should have redundant paths between every resource and an access point and automatic routing to switch the traffic to the available path without loss of data or time. Access/entry point controls: Most network controls are put ...
