Layered security: Network intrusion defence and access control
The third layer of a secure, layered security position has three components: firewalls with intrusion prevention systems, virtual private networks and web security and filtering. More technical that the previous steps to total security, these three systems are outlined below.
A properly deployed firewall protects the perimeter of your network to report and block attacks. Ideally, your firewall will not allow any traffic from outside your network directly into your network – all traffic should authenticate at the perimeter.
Virtual Private Networks (VPNs)
Connect your offices with point-to-point VPN tunnels between firewalls. Your system should be configured so that remote users require two factor authentication and an IPSec VPN which allows access only to resources they require.
Web Security and Filtering
With proper web security and filtering, you can stop malicious traffic from entering your network. This reduces the chances of malware infections (e.g. Ransomware) by cutting off paths to malicious Command and Control Servers. Additionally, web security and filtering helps to enforce HR acceptable use policies in a granular fashion – reducing HR risks and improving productivity.
