PoP, the adversary padlock
The PoP has been mentioned briefly in previous chapters to explain certain concepts of IOCs and adversary behaviors. In this section, we will look at it in detail. The PoP describes the relationships between IOCs and illustrates the amount of pain it will cause adversaries should you block those IOCs. Whenever you deny an IOC, the adversary needs to change one or more of their TTPs to carry on with the attack. In the following subsection, we look at the types of indicators used in the PoP and their application.
PoP indicators
IOCs do not carry the same weight (value or importance) when it comes to security monitoring. Understanding which IOC is a priority in a cyberattack can help CTI analysts reduce threat impact and complicate the adversaries' lives. The PoP, as shown in the following figure, was created by David J. Bianco in 2013 (https://bit.ly/3p2caLJ). It comprises six IOCs associated with the pain index:
