Cybersecurity experts Yuri Bobbert and Dr. Barry Derksen have co-authored a compelling new article in the ISACA Journal, titled “Certified but Vulnerable: The Silent Risks of Unvalidated Security Controls.”
The article sheds light on the often-overlooked vulnerabilities that persist in organizations, even those with recognized security certifications. Bobbert and Derksen argue that a disconnect between what organizations know and what they effectively implement—the Knowing–Doing Gap—can lead to severe security failures, including so-called black swan events.
Key insights from the article include:
- How cognitive biases create blind spots in digital security strategies
-
Why formal certification does not guarantee operational security
-
The need for continuous validation of controls, not just documentation
-
Practical guidance on how to close the Knowing–Doing Gap
This publication is a call to action for CISOs, security auditors, risk managers, and business leaders to rethink how assurance and effectiveness are measured within their digital resilience programs.
