Value Drivers

  • Preventive and detective security controls established as necessary
  • Ensured data confidentiality, integrity and availability
  • Maintained system availability for business processing
  Risk Drivers
  • Undetected security violations
  • Costly compensating controls
  • Gaps between considered security controls and actual threats and risks

Hide Control Practices  help

  1. Design approaches and solutions to security and availability that adequately meet the defined requirements. These approaches should take into account the organisational security architecture and policies, industry security and privacy best practices, and regulatory and compliance requirements for security and privacy.
  2. Consider the security and availability infrastructure already in place. Where possible, build on and extend these capabilities.
  3. Consider access rights and privilege management, protection of sensitive information at all stages, authentication and transaction integrity, and automatic recovery.
  4. Define how the solutions for security and availability in the infrastructure will be integrated with the application, paying particular attention to transactions, local and wide area networks (e.g., Internet), shared and federated databases, access control mechanisms, load detection, and recovery mechanisms.
  5. Confirm the design of security, availability, access management, authentication and protection of transaction integrity with IT technical authorities and, as appropriate, subject matter experts. Obtain their sign-off on and approval of the design. Also confirm with business process owners that the design meets their security and availability requirements using non-technical walk-throughs, where necessary, to confirm understanding.
