Preventing security breaches requires proactive security controls, and the approval of identity requests ensures that only authorized individuals gain access to systems and data.
* Types of Security Controls:
* Preventive Controls (Stop security incidents before they happen)
* Detective Controls (Identify security breaches after they occur)
* Corrective Controls (Address security issues after detection)
* Why Identity Request Approval is the Most Effective Preventive Control?
* User access approval ensures that only verified personnel receive credentials.
* According to IIA GTAG on Identity and Access Management, user provisioning must follow strict approval workflows to prevent unauthorized access.
* By restricting access before a breach occurs, organizations reduce risks related to insider threats, phishing attacks, and credential misuse.
* Why Not Other Options?
* B. Access Logging:
* Access logs record activity but do not prevent security breaches.
* C. Monitoring Privileged Accounts:
* Monitoring privileged accounts helps detect suspicious activity but does not stop unauthorized access beforehand.
* D. Audit of Access Rights:
* Regular audits ensure compliance but do not actively prevent unauthorized access in real- time.
* IIA GTAG - Identity and Access Management
* IIA Standard 2120 - Risk Management and IT Controls
* COBIT 2019 - Access Control and Security Management
