Question

A security administrator at Company XYZ is trying to develop a body of knowledge to enable heuristic and behavior based security event monitoring of activities on a geographically distributed network. Instrumentation is chosen to allow for monitoring and measuring the network. Which of the following is the BEST methodology to use in establishing this baseline?

Options

  • AModel the network in a series of VMs;
  • BCompletely duplicate the network on virtual machines;
  • CInstrument the operational network; simulate extra traffic on the network;
  • DSchedule testing on operational systems when users are not present;

Explanation

Modeling the network in a series of VMs is the best approach for safely establishing a behavioral baseline. It lets you simulate normal traffic patterns and operating conditions in a controlled, isolated environment without putting production systems at risk. Once the model is validated, you can instrument the real network with confidence. Option B (fully duplicating the network in VMs) is prohibitively expensive and complex. Option C introduces simulated extra traffic onto the live operational network, which risks distorting the very baseline you're trying to capture and can impact production performance. Option D (testing when users aren't present) defeats the purpose - you need to capture normal user behavior, not an empty network.
