 The most reliable way for an IS auditor to evaluate the operational effectiveness of an organization’s data loss prevention (DLP) controls is to verify that confidential files cannot be transmitted to a personal USB device. This is because DLP controls are designed to prevent the loss, leakage or misuse of sensitive data through breaches, ex-filtration transmissions and unauthorized use1. A personal USB device is a common way for data to be stolen or compromised, as it can bypass network security measures and allow unauthorized access to confidential files. Therefore, testing the DLP controls by attempting to copy or transfer confidential files to a personal USB device can provide a direct and objective evidence of whether the DLP controls are working as intended or not.

The other options are less reliable ways for an IS auditor to evaluate the operational effectiveness of an organization’s DLP controls. Reviewing data classification levels based on industry best practice is a way to assess the adequacy of the organization’s data protection policies, but it does not measure how well the DLP controls are implemented or enforced in practice. Verifying that current DLP software is installed on all computer systems is a way to check the technical configuration of the DLP solution, but it does not test how well the DLP software detects and prevents data loss incidents in real scenarios. Conducting interviews to identify possible data protection vulnerabilities is a way to gather qualitative information from stakeholders, but it does not provide quantitative or empirical data on the actual performance of the DLP controls.

The best course of action for a security administrator who is called in the middle of the night by the on-call programmer who needs access to the live system is to give the programmer an emergency ID for temporary access and review the activity. This is because:

Requiring that a change request be completed and approved may delay the resolution of the problem and cause further damage or disruption to the system or business operations. A change request is a formal document that describes the proposed change, its rationale, impact, benefits, risks, costs, and approval process. A change request is usually required for planned or scheduled changes, not for emergency or urgent changes.

Giving the programmer read-only access to investigate the problem may not be sufficient or effective, as the programmer may need to perform actions or tests that require write or execute permissions. Read-only access means that the user can only view or copy data or files, but cannot modify or delete them.

Reviewing activity logs the following day and investigating any suspicious activity may not prevent or detect any unauthorized or malicious actions by the programmer in real time. Activity logs are records of events and actions that occur within a system or network. Activity logs can provide evidence and accountability for system activities, but they are not proactive or preventive controls.

Therefore, giving the programmer an emergency ID for temporary access and reviewing the activity is the best course of action, as it allows the programmer to access the live system and resolve the problem quickly, while also ensuring that the security administrator can monitor and verify the programmer’s activity and revoke the access when it is no longer needed. An emergency ID is a temporary account that grants a user elevated privileges or access to a system or resource for a specific purpose and duration. An emergency ID should be:

Created and authorized by a security administrator or manager

Assigned to a specific user and purpose

Limited in scope and time

Logged and audited

Revoked and deleted after use

Some of the best practices for emergency access to live systems are12:

Establish clear policies and procedures for requesting, approving, granting, monitoring, reviewing, and revoking emergency access

Define criteria and scenarios for emergency access, such as severity, impact, urgency, and risk

Implement controls to prevent unauthorized or unnecessary use of emergency access, such as multifactor authentication, approval workflows, alerts, notifications, and time restrictions

Implement controls to track and audit emergency access activities, such as logging, reporting, analysis, and investigation

Implement controls to ensure accountability and responsibility for emergency access users, such as attestation, justification, documentation, and feedback

The most critical factor for the success of an information security program is management’s commitment to information security. Management’s commitment to information security means that the senior management supports, sponsors, funds, monitors and enforces the information security program within the organization. Management’s commitment to information security also demonstrates leadership, sets the tone and culture, and establishes the strategic direction and objectives for information security. User accountability for information security, alignment of information security with IT objectives, and integration of business and information security are also important factors for the success of an information security program, but they are not as critical as management’s commitment to information security, as they depend on or derive from it. References: Info Technology & Systems Resources | COBIT, Risk, Governance … - ISACA, IT Governance and Process Maturity
