Polling the remote service at regular intervals provides an independent and objective measurement of system uptime and responsiveness. This method produces verifiable availability data that can be compared directly against SLA commitments, ensuring accuracy for performance evaluation and contractual payment validation.

The most important aspect for an IS auditor to verify is that the end-user computing (EUC) policy defines appropriate control procedures - such as data validation, access management, version control, and backup requirements. These controls are essential to mitigate risks associated with user-developed applications and ensure data integrity and compliance.

The best way to protect against the internal threat of sensitive data disclosure is to implement a Data Loss Prevention (DLP) solution. DLP solutions are specifically designed to monitor and prevent the unauthorized transfer, sharing, or disclosure of sensitive data. They can enforce policies regarding data handling, such as restricting data access and preventing it from being leaked through various channels, including email, USB drives, and cloud services. This helps protect against both intentional and unintentional internal threats.
