How confident are you in your security program (Tools, systems, controls etc)?
In the context of information security, the terms validated confidence and assumption confidence reflect different levels of assurance in the accuracy or reliability of information, decisions, or controls:
Validated Confidence
Definition: Confidence based on evidence, verification, and thorough testing. This involves using measurable, repeatable methods to confirm that a security control, process, or decision is effective and aligned with expectations.
Characteristics:
- Supported by data, documentation, or third-party assessments.
- Includes security audits, penetration testing results, risk assessments, or compliance certifications.
- Provides higher assurance due to objective validation.
Example in Information Security:
- Confidence in a firewall's effectiveness after it has been tested against specific threat scenarios.
- Belief in the accuracy of a vulnerability scan after reviewing detailed scan results and cross-checking with known vulnerabilities.
Assumption Confidence
Definition: Confidence based on beliefs, expectations, or untested assumptions rather than direct evidence or verification.
Characteristics:
- Lacks strong evidence or rigorous validation.
- Often used in the absence of time, resources, or information to verify controls or processes.
- Carries a higher risk due to potential blind spots or overlooked issues.
Example in Information Security:
- Assuming a system is secure because it has never been breached, without conducting regular security assessments.
- Believing an employee understands phishing risks because they completed one training session, without verifying behavior through phishing simulations.
Importance of Distinguishing
- Relying on validated confidence ensures robust security and minimizes risks of vulnerabilities or breaches.
- Over-reliance on assumption confidence can lead to unmitigated risks and a false sense of security.
Practical Recommendation
To strengthen information security posture:
- Identify areas where assumption confidence exists.
- Transition to validated confidence by implementing regular assessments, monitoring, and testing.
- Document and track validation processes to ensure continuous improvement.
