There are many layers to consider when addressing network security across an organization. Attacks can happen at any layer in the network security layers model, so your network security hardware, software and policies must be designed to address each area. Network security typically consists of three different controls: physical, technical and administrative.
Network Access Control
To ensure that potential attackers cannot infiltrate your network, comprehensive access control policies need to be in place for both users and devices. Network access control (NAC) can be set at the most granular level. For example, you could grant administrators full access to the network but deny access to specific confidential folders or prevent their personal devices from joining the network.
Antivirus and Anti-malware Software
Antivirus and anti-malware software protect an organization from a range of malicious software, including viruses, ransomware, worms and trojans. The best software not only scans files upon entry to the network but continuously scans and tracks files
Firewalls, as their name suggests, act as a barrier between the untrusted external networks and your trusted internal network. Administrators typically configure a set of defined rules that blocks or permits traffic onto the network.
Network security should be a high priority for any organization that works with networked data and systems. In addition to protecting assets and the integrity of data from external exploits, network security can also manage network traffic more efficiently, enhance network performance and ensure secure data sharing between employees and data sources.
