Network Infrastructure Security – It is a procedure of protecting the main networking infrastructure by applying preventative steps to avoid theft of important data and resources, modification, deletion, and illegal access in any network. These preventive security steps may contain firewalls, wireless security, behavioral analytics, access control, intrusion prevention systems, and virtual private network (VPN). The main function of network infrastructure security is to rely on ongoing procedures and practices to protect the basic business IT infrastructure.

Network Infrastructure Security contains a holistic approach for ongoing best practices and processes to make sure that the main networking infrastructure remains safe or protected from cyber-attacks. The CISA (Cybersecurity and Infrastructure Agency) inspires network administrators and users to apply or implement several recommendations for better security of network infrastructure are given below –

1. To reduce or limit unnecessary lateral communications.
2. To safe or secure access to infrastructure devices
3. To separate or segregate and segment networks and functions.
4. To authorize the integrity of software and hardware.
5. To harden network devices
