Network security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. For any enterprise, getting the network security basics right is critical, and next-generation threats require a next-generation approach.

The challenge today for network security architects is to ensure all security tools work with each other rather than alongside each other, and not just at the network periphery, but inside the network. Even the network threats are as powerful or may be even more powerful than the firewalls. Implementation of most of the network security systems is complex and tedious, and hence requires a trained staff to oversee updates and maintenance. This ultimately leads to high overhead costs and thus negligence which further keeps the organisation’s data at risk, vulnerable to cyber attacks.

Network security helps organizations protect the ongoing usability of assets with integrity of data and continuity of operations.Next-generation network security tools aim to correct this by providing overlapping protection to implement a defence-in-depth strategy. Firewalls, secure Web gateways, and intrusion prevention systems thwart attacks at the network's edge, while malware sandboxes provide strategic depth, and network access control tools protect the network from within.
