Current Network infrastructure contains big number of interconnected devices. Devices are used to transport communications needed for data, applications, services, and multimedia. Routers and firewalls are major points of these systems, however there is still many other devices exist in the network, such as switches, load-balancers, etc. These devices should implement security solutions for protecting their unauthorized usage.
During last years, vulnerable devices have been the attack-vector for sophisticated hackers and threat actors. Due to this in such environment, there has appeared great need to improve network security. Unlike hosts that receive significant administrative security attention and for which security tools such as anti-malware exist, network devices are often working in the background with little oversight—until network connectivity is broken or diminished. Hackers take advantage of this fact and often target network devices as weak points of network infrastructure.
A great number of network devices - including routers, switches, and gateways - exhibited security vulnerabilities, exposing their organizations to external and internal security attacks.
Identifying the vulnerabilities of a network device is one of the most important security task, which each Network Service Provider should do regularly.
