While a bit older (it’s from 2009), this is an excellent guide to surveillance and security in resistance movements. It includes a thorough overview of what surveillance is and why the government uses it against its political opponents. It covers in great detail how governments (and other forces) engage in surveillance in both physical and technical forms. There are also tips for evading and minimizing surveillance, tips on recognizing and dealing with surveillance via informants, and historical examples of surveillance against political movements.
Security & Counter-Surveillance
Security is vital to the success & survival of the resistance movement. This is because we have an enemy who actively works to undermine, neutralize, & ultimately destroy us. Failure to remain aware of security concerns can mean the difference between victory or defeat, freedom or imprisonment, life or death. Not only for yourself, but others around you.
