Art of War - Walled Cities

The Art of War by Sun Tzu is among the most famous works on military strategy. Over the coming weeks, Accellis will adapt many of these timeless lessons to the modern cybersecurity theater. By understanding fundamentals of security and military theory, legal, financial, and other industries will be in a better position to respond to these threats.


Sun Tzu said, “…the worst policy of all is to besiege walled cities.”


A timeless military axiom, prolonged warfare can be the bane of military conquest. With your firewall, antivirus, antispam, logging, patching, dual factor authentication, password expiry, Active Directory, group policy, software rights administration, backups, disaster recovery, mobile device management, security training, and ongoing assessment, your firm is a walled city. These are your walls, moat, and drawbridge. In being well defended, it can be too costly, in terms of computing power, time, and human capital, to repeatedly attack you. The costs to attack a well-defended firm will be comparatively high relative to that firm’s competitors, meaning opportunity cost will drive hackers towards lower hanging fruit and away from you.
