Microsegmentation is a network security approach that enables security architects to construct network security zones boundaries per machine in data centers and cloud deployments in order to segregate and secure workloads independently. [1] [2] It is now also used on the client network as well as the data center network.
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.
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data ...
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet. The protocol is widely used in applications such as email , instant messaging , and voice over IP , but its use in securing HTTPS remains the most publicly visible.
Network segmentation in computer networking is the act or practice of splitting a computer network into subnetworks, each being a network segment. Advantages of such splitting are primarily for boosting performance and improving security.
It can allow for separate security management and operational direction. COI's generally do not dictate separate internal security policies (e.g., password policies, etc.) because they fall under the jurisdiction and management of the LAN or WAN owners. They can and often do have a laxed subset of the overall Network security policy.
Endpoint security management is a software approach that helps to identify and manage the users' computer and data access over a corporate network. [3] This allows the network administrator to restrict the use of sensitive data as well as certain website access to specific users, to maintain, and comply with the organization's policies and standards.
Network security is a umbrella term to describe 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]
