network security layers

Standard security management practice is to test security to confirm proper configuration, performance, and strength against attacks and exploits. When a firewall is updated or its settings modified, another round of firewall testing should be conducted.

Some approaches to firewall testing that do not disrupt the production environment are:

  • Simulated firewall tests: Use an attack simulator to transmit attack packets to the firewall
  • Virtual firewall tests: Are performed in a virtualized network environment using a virtualization tool
  • Laboratory tests: Are run in nonproduction subnets on a duplicate of the production environment

Which approach do you think would be most effective? Why?
