Network security consists of numerous levels of defence at the network’s edge and within the network. Policies and controls are implemented at each network security layer. Authorized users can access network resources, but malicious parties cannot carry out attacks or threats.
A network infrastructure comprises equipment linked together, such as computers, servers, and wireless networks. These devices are vulnerable to cyber security threats and attackers. As organizations grow, their network infrastructure complexity grows, opening new areas attackers can pursue.
