An effective internal audit quality assurance and improvement program is demonstrated by the ongoing identification of opportunities for continuous improvement, showing that internal audit activities are regularly evaluated and enhanced to maintain quality, effectiveness, and alignment with professional standards.

The greatest risk is unintentional human error, such as misaddressing an email. Security awareness training equips users to recognize PII and verify recipients. MFA protects account access but not outbound emails. IDS detects network threats, not email content. Audit trails only provide after-the-fact evidence.
