Cyber Security & Cyber Resilience framework for Stock Brokers/Depository Participants

Updated: May 16

Stock brokers and depository participants perform significant functions in providing services to holders of securities. Thus, there is a need for maintaining robust cyber security and cyber resilience framework to protect the integrity of data and guard against breaches of privacy.

A framework on cyber security and cyber resilience has been designed by SEBI, which would be required to be complied by all Stock Brokers and Depository Participants registered with SEBI.

This is already effective since April 01, 2019, still not complied by many. CIA is important. Cyber-attacks and threats attempt to compromise the same. Cyber security framework includes measures, tools and processes that are intended to prevent cyber-attacks and improve cyber resilience. Cyber Resilience is an organization’s ability to prepare and respond to a cyber-attack and to continue operation during, and recover from, a cyber-attack. What is required as a part of this framework to be undertaken by Stock Brokers/ Depository Participants?

1. Formulation of a comprehensive Cyber Security and Cyber Resilience Policy Document, approved by the Board / Partners / Proprietor of the Stock Broker / Depository Participants, and reviewed annually.

2. The Cyber Security Policy of Stock Brokers trading through APIs based terminal / Depository Participants should consider the principles prescribed by National Critical Information Infrastructure Protection Centre (NCIIPC) of National Technical Research Organization (NTRO), Government of India (titled ‘Guidelines for Protection of National Critical Information Infrastructure’) and subsequent revisions, if any, from time to time.

3. There should be a ‘Designated Officer’ whose function would be to assess, identify, and reduce security and Cyber Security risks, respond to incidents, establish appropriate standards and controls, and direct the establishment and implementation of processes and procedures as per the Cyber Security Policy.

4. The Board / Partners / Proprietor of the Stock Brokers / Depository Participants shall constitute an internal Technology Committee comprising experts. This Technology Committee should on a half yearly basis review the implementation of the Cyber Security and Cyber Resilience policy, among other responsibilities. The review shall be placed before the Board/ Partners/ Proprietor of the Stock Brokers / Depository Participants for appropriate action.

5. Stock Brokers/ Depository Participants should identify critical assets based on their sensitivity and criticality for business operations, services and data management.
