The ISO Controls You Must Know To Fortify Your Defenses
You step away from your desk to grab a coffee, leaving your computer unlocked. You’re only gone for a minute. What’s the worst that could happen?
This Isn’t Just About Locking Your Screen
This incident is a textbook example of a failure in a fundamental security principle: the Clear Desk and Clear Screen policy. It’s listed as control 7.7 in the ISO framework for a reason. It is a critical Physical Control designed to prevent unauthorized access to sensitive information.
But notice what happens when this simple rule is broken. It immediately triggers the need for another control: the Disciplinary Process (People Control 6.4).
This is the core of what mastering ISO teaches you: security is not a checklist of isolated rules. It is a dynamic, interconnected system where People Controls and Physical Controls must work in perfect harmony.
A non-disclosure agreement (6.6) is useless if your screen is unlocked for everyone to see (7.7). Physical entry controls (7.2) mean nothing if an authorized person can access a colleague’s sensitive data. Every control, from cabling security to equipment disposal, is a link in a chain. If one link breaks, the entire organization is exposed.
Are You In Control?
You don’t need to learn these lessons the hard way. You don’t need to wait for your own “resignation letter” moment to understand the devastating impact of a single security failure.
True security control comes from understanding the complete framework—knowing not just the what, but the why and the how. It’s about building a culture of security so robust that locking your screen becomes as instinctual as breathing.
Protect your assets. Protect your career. Master the controls that matter.
