Understanding Hostile Reconnaissance
A critical aspect of detecting and deterring hostile reconnaissance at a site is knowing the threat that you face and understanding where hostiles might conduct their reconnaissance from.
While an organisation may face a variety of different threats with different attack scenarios, there are likely to be commonalities in information requirements across these. Therefore measures put in place to disrupt hostile reconnaissance can be effective over a wide range of threats.
Given that not all threats are the same, a useful way of understanding those particular to an organisation is to consider the mind-set of the hostile.
CPNI has produced guidance to help organisations understand what hostile reconnaissance is, where it may be conducted and what can be done to deter it.
