Networksecurity is a layered security process comprising of both hardware and software. If one layer of security fails others stand to prevent the network. The software must be periodically updated to protect the network from new threats. The various components of network security that work in conjugation to provide lesser maintenance and improved security are- Antivirus packages that prevent maximum virus threats if updated and maintained, Firewall to prevent unauthorized access to network, Virtual private networks(VPN) to create secure private network, encryption etc.
