Remote wipe is not always 100% effective: While remote wiping can delete most user data, some residual data may remain on the device, especially in cases where:
The device has built-in storage redundancies.
Deleted data can be recovered using forensic tools.
The remote wipe command fails to execute properly due to network issues or device settings.
Security Risk: This limitation poses a risk for organizations handling sensitive or confidential data, as unauthorized individuals may recover wiped data.
IIA Standard 2110 - Governance: Internal auditors must assess how organizations manage IT security risks, including risks related to mobile devices and data protection.
IIA Practice Guide: Auditing Cybersecurity Risks highlights the need to evaluate mobile security controls and limitations of data removal techniques.
A. Encrypted data cannot be locked to prevent further access (Incorrect)
Encrypted data remains secure even if the device is lost.
Many enterprise security solutions allow organizations to revoke encryption keys remotely, making data inaccessible.
IIA Standard 2120 - Risk Management advises that effective encryption reduces the impact of data loss.
B. Default settings cannot be restored on the device. (Incorrect)
Most remote wipe solutions allow factory reset, restoring the device to default settings.
Many mobile device management (MDM) tools support full device restoration.
D. Mobile device management software is required for a successful remote wipe. (Incorrect)
While MDM enhances remote wiping capabilities, it is not strictly required.
Some consumer and enterprise mobile operating systems (e.g., iOS, Android) provide built-in remote wipe functionality without MDM.
Explanation of Answer Choice C (Correct Answer):Explanation of Incorrect Answers:Conclusion:Remote wipe has limitations, and the inability to completely remove all data from the device (Option C) is a primary concern.
