The CBSE has acknowledged loopholes in its On-Screen Marking (OSM) system and launched a high-level cybersecurity exercise to strengthen the Onmark portal following concerns raised about potential vulnerabilities. The board says experts from government agencies and IITs have been deployed to identify and contain weaknesses, with continuous monitoring now in place. The controversy escalated after some Class 12 students reported discrepancies in uploaded answer sheets, sparking questions about the integrity of the digital evaluation process. While CBSE has maintained that digital evaluation remains a globally accepted practice, it has admitted the need for stronger safeguards and has welcomed inputs from ethical hackers and cybersecurity researchers to improve the platform.
