Following a breach, the maximum amount of time before customers must be notified that their personal information may have been compromised depends on the industry regulations that apply to the organization.
Different industries and jurisdictions may have different legal and regulatory requirements for breach notification, such as the General Data Protection Regulation (GDPR) in the European Union, the Health Insurance Portability and Accountability Act (HIPAA) in the United States, or the Personal Information Protection and Electronic Documents Act (PIPEDA) in Canada. Industry standards, incident response plans, and information security policies are not as authoritative as industry regulations in determining the breach notification time frame.

The most effective way for an organization to help ensure agreed-upon action plans from an IS audit will be implemented is to ensure ownership is assigned. This means that the management of the audited area should accept responsibility for implementing the action plans and report on their progress and completion to the audit committee or senior management. This will ensure accountability, commitment, and follow-up for the audit recommendations34.

Stress testing is designed to evaluate a system's performance under extreme conditions1. It is typically carried out in a test environment that closely mirrors the production environment, using production workloads1. This approach ensures that the test results accurately reflect how the system would perform under similar conditions in the production environment1. Using a test environment also prevents any disruptions or damage to the production environment during testing1.

To detect unauthorized disclosure of confidential documents sent over corporate email, monitoring all emails based on pre-defined criteria is the best approach. This involves setting up automated monitoring systems that analyze email content, attachments, and metadata to identify any potential unauthorized disclosures. By defining specific criteria (such as keywords related to confidential information), organizations can proactively detect and prevent leaks. Requiring encryption before sending documents (option A) is important but does not address monitoring for unauthorized disclosures. Firewalls (option B) protect the network but do not specifically focus on email content. Reporting outgoing emails marked as confidential (option C) relies onuser self-reporting and may not catch all incidents12. References: 1(https://www.isaca.org/resources/isaca-journal
