Background of the Case
In 2021, a highly classified file containing the National Infrastructure Security Blueprint (NISB)—a strategic plan for securing critical infrastructure like power grids, railways, and defense installations—went missing from the Ministry of Home Affairs (MHA).
The file disappearance posed a severe national security threat, as it contained:
Detailed risk assessments of key government installations.
Plans for cyber and physical security upgrades.
Coordination strategies between intelligence agencies, paramilitary forces, and disaster management teams.
This incident triggered an emergency response, and senior officers quickly mobilized to recover the file while following strict Departmental Security Instructions (DSI).
Restricted File Access in the MHA’s Cybersecurity Division
The NISB file was marked "Top Secret", stored in a high-security cabinet with limited access to select officers.
The document was being physically reviewed by a Joint Secretary (Level 14 officer) for final amendments before submission to the Prime Minister’s Office (PMO).
Unauthorized Transfer to Another Section
Due to miscommunication, a Section Officer mistakenly transferred the file to an external records department without updating the official logbook.
Security personnel failed to verify the file movement due to a gap in internal compliance with security protocols.
Unnoticed Misplacement During an Office Shift
The records department was undergoing a relocation, and several classified files were temporarily stored in an unsecured area.
The NISB file was mixed up with older, declassified documents, and was unknowingly moved to a different floor of the MHA building.
Realization of the Missing File
When the Joint Secretary requested the file, it was nowhere to be found.
Immediate security breach alert was raised, and senior officers invoked Departmental Security Protocols for lost classified files.
✅ Step 1: Restricted Entry and Immediate Search
The building was temporarily locked down, restricting entry and exit of personnel.
Only verified officers with clearance were allowed in the affected sections.
