Network Infrastructure Security, typically applied to enterprise IT environments, is a process of protecting the underlying networking infrastructure by installing preventative measures to deny unauthorized access, modification, deletion, and theft of resources and data. These security measures can include access control, application security, firewalls, virtual private networks (VPN), behavioral analytics, intrusion prevention systems, and wireless security.
Network Infrastructure Security requires a holistic approach of ongoing processes and practices to ensure that the underlying infrastructure remains protected. The Cybersecurity and Infrastructure Security Agency (CISA) recommends considering several approaches when addressing what methods to implement.
The greatest threat of network infrastructure security is from hackers and malicious applications that attack and attempt to gain control over the routing infrastructure. Network infrastructure components include all the devices needed for network communications, including routers, firewalls, switches, servers, load-balancers, intrusion detection systems (IDS), domain name system (DNS), and storage systems. Each of these systems presents an entry point to hackers who want to place malicious software on target networks.
Although there are any number of damaging attacks that hackers can inflict on a network, securing and defending the routing infrastructure should be of primary importance in preventing deep system infiltration.
Network infrastructure security, when implemented well, provides several key benefits to a business’s network.
A variety of approaches to network infrastructure security exist, it is best to adhere to multiple approaches to broaden network defense.
