Cyber security - vulnerabilities, Computer Network Security

Assignment Help:

The world has to deal with newly released vulnerabilities on a daily basis.  These vulnerabilities eventually lead to active exploits of systems, and it is our job as cyber security professionals to stop that from happening.

I would like for each of you to research a different set of (5) vulnerabilities have been release since Jan 1, 2010 and report back on(I should see 4 separate answers/signatures for each of the 5 vulnerabilities you choose):

1) What systems, services are affected;

2) What attack vectors could be used to exploit the vulnerable systems;

3) What mitigation factors could be used to stop the attack of the vulnerability;

4) We are going to build IDS signatures using English terms and not technical terms.  I would like for each of you to explain how you would build an "IDS Signature" to help detect each of the (5) vulnerabilities.  Some basics of the IDS rules:

  • Source/Destination Ports
  • Source/Destination IP's
  • Source/Destination protocol
  • Unique detection string (network sensor)
  • Unique application behavior (Host sensor)
  • Location of sensor (Host or network)
  • Timed sensor
  • Multiple hits
  • Action (Alert, firewall block, log)
  • Exceptions
  • Take into consideration false positives and false negatives
