Defeat the Asymmetry. Apply Common Sense.
May 2025
Security isn’t fair, and that’s the point.
Attackers only need to be right once, while defenders have to be right every time, and that asymmetry explains why so many security programs collapse under the weight of their own overthinking.
Brutalist Security works against that asymmetry by changing the equation instead of accepting it. Rather than trying to predict every move an attacker might make, it focuses on building common-sense defenses that hold up under stress.
Reducing the attack surface comes first, since attackers win whenever defenders waste time guarding trivia instead of hardening what actually counts. Assuming compromise comes next, so systems get built to expect failure and limit the blast radius rather than chase a perfect defense that never arrives. Simplifying the stack is important too, because every unnecessary tool adds another weak link and another blind spot. Anything that isn't pulling its weight should get cut.
Security works as a job for realists, and the way forward comes from cutting the noise and making moves that hold up under fire rather than reaching for a new acronym or a more complex framework.
Defeating the asymmetry starts with applying common sense consistently, not with trying to outsmart it.
