3. Strengthen Access Controls
Tom’s Third Step Ensuring Proper Access Management
Tom strengthens access controls to ensure that only authorized personnel have access to critical systems and data. This includes implementing multifactor authentication (MFA) and rolebased access control (RBAC).
Key Access Control Measures
MultiFactor Authentication (MFA) Requires multiple forms of verification.
RoleBased Access Control (RBAC) Assigns access rights based on job roles.
Regular Audits Conducts regular audits of access permissions.
