Network behaviour analysis (NBA) is a network monitoring
program that ensures the security of a proprietary network. NBA helps in
enhancing network safety by watching traffic and observing unusual activity and
departures of a network operation.
Network behaviour analysis monitors the inside happenings of
an active network by collecting data from many data points and devices to give
a detailed offline analysis. It is constantly watching the network, marking
known and unknown activities, new and unusual patterns and indicating potential
threats by flagging. The program also checks and accounts for change in
bandwidth and protocol being used during communication. This is particularly
applicable in finding a potentially dangerous data source or website.
The duty of a network behaviour analysis program is to
reduce the labour and time expended by network administrators in detecting and
resolving network issues. It is thus an enhancement to protect the network
along with firewalls, antivirus software and spyware detection tools. Conventional
methods of defending a network against harmful data include packet checking,
signature recognition and real-time blocking of malicious sites and data.
