Network security refers to the policies, processes, and practices adopted to prevent, detect, and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. It involves creating a secure infrastructure for devices, applications, users, and data to work in a secure manner. Network security is important because it keeps sensitive data safe from cyber attacks and ensures the network is usable and trustworthy.
Here are some key points about network security:
-
Access control: This is the first line of defense in network security. It restricts the movement of bad actors throughout the network.
-
Virus and antivirus software: This software is used to detect and remove viruses and other malicious software.
-
Application security: This involves securing applications and software from unauthorized access and modification.
-
Network analytics: This involves analyzing network traffic to detect and prevent security threats.
-
Types of network-related security: This includes endpoint security, web security, wireless security, and more.
-
Firewalls: Firewalls are used to monitor and control incoming and outgoing network traffic based on predetermined security rules.
-
VPN encryption: This is used to encrypt data transmitted over a network to prevent unauthorized access.
Network security is enforced using a combination of hardware and software tools. It is a vital aspect of protecting client data and information, keeping shared data secure, and ensuring reliable access and network performance as well as protection from cyber threats.
