What is a characteristic of an IPS atomic signature?

• it can be slow and inefficient to analyze traffic
• it requires several pieces of data to match an attack
• it is a stateful signature
• it is the simplest type of signature
  

  Answers Explanation & Hints: There are two types of IPS signatures: Atomic – This is the simplest type of signature because it does not require the IPS to maintain state information and it can identify an attack with a single packet, activity, or event. Composite – This is a stateful type of signature. It requires that the IPS maintain state information to match an attack signature.
