Network security is essentially a set of rules and configurations formulated to protect the accessibility, confidentiality, and integrity of computer networks and data with the help of software and hardware technologies.
Types of network security :
Network access control : To prevent attackers and infiltrations in the network, network access control policies are in place for both users and devices at the most granular level. For example, access authority to network and confidential files can be assigned and regulated as needed.
Antivirus and antimalware software : Antivirus and antimalware software are used to continuously scan and protect against malicious software, viruses, worms, ransomware, and trojans.
Firewall protection : Firewalls act as a barrier between your trusted internal network and an untrusted external network. Administrators can configure a set of defined rules for the permission of traffic into the network.
Virtual private networks (VPNs) : VPNs form a connection to the network from another endpoint or site. For example, an employee working from home uses a VPN to connect to the organization’s network. The user would need to authenticate to allow this communication. The data between the two points is encrypted.
