iv. Password policy / Authentication Mechanism: Conducting reviews of obsolete accounts, enabling multi-factor authentication.;
v. Privilege Management: Implementing Maker-Checker framework and zero trust models with identity verification;
vi. Cybersecurity controls: Including but not limited to deploying web/email filters on the network, scanning email content;
vii. Outsourced Agencies: Analysing concentration risk when outsourcing several critical services to the same vendor; and
viii. Audit and ISO certification: SEBI instructions on external audits of REs by independent auditors empaneled with CERT-In to be complied with and ISO certification to be obtained and audit process due diligence to be conducted.
Additional requirements include taking measures to avoid phishing and data protection breach, strengthening cloud service security and implementation of advisories by CSIRT-Fin/CERT.
