Management Practice Inputs Outputs DSS05.04 Manage user identity and logical access. Ensure that all users have information access rights in accordance with their business requirements and co-ordinate with business units that manage their own access rights within business processes. From Description Description To APO01.02 Definition of IT-related roles and responsibilities APO03.02 Information architecture model Activities Approved user access rights Results of reviews of users accounts and privileges 1. Maintain user access rights in accordance with business function and process requirements. Align the management of identities and access rights to the defined roles and responsibilities, based on least-privilege, need-to-have and need-to-know principles. 2. Uniquely identify all information processing activities by functional roles, co-ordinating with business units to ensure that all roles are consistently defined, including roles that are defined by the business itself within business process applications. 3. Authenticate all access to information assets based on their security classification, co-ordinating with business units that manage authentication within applications used in business processes to ensure that authentication controls have been properly administered. 4. Administer all changes to access rights (creation, modifications and deletions) to take effect at the appropriate time based only on approved and documented transactions authorised by designated management individuals. 5. Segregate and manage privileged user accounts. 6. Perform regular management review of all accounts and related privileges. 7. Ensure that all users (internal, external and temporary) and their activity on IT systems (business application, IT infrastructure, system operations, development and maintenance) are uniquely identifiable. Uniquely identify all information processing activities by user. 8. Maintain an audit trail of access to information classified as highly sensitive. Management Practice Inputs Outputs DSS05.05 Manage physical access to IT assets. From Description Description To Define and implement procedures to grant, limit and revoke access to premises, buildings and areas Approved access requests Internal according to business needs, including emergencies. Access to premises, buildings and areas should be �� apply to all persons entering the premises, including staff, temporary staff, clients, vendors, visitors or any other third party. Access logs DSS06.03 Activities 1. Manage the requesting and granting of access to the computing facilities. Formal access requests are to be completed and authorised by management of the IT site, and the request records retained. The forms should specifically identify the areas to which the individual is granted access. �� 3. Log and monitor all entry points to IT sites. Register all visitors, including contractors and vendors, to the site. 4. Instruct all personnel to display visible identification at all times. Prevent the issuance of identity cards or badges without proper authorisation. 5. Require visitors to be escorted at all times while on-site. If an unaccompanied, unfamiliar individual who is not wearing staff identification is identified, alert security personnel. 6. Restrict access to sensitive IT sites by establishing perimeter restrictions, such as fences, walls, and security devices on interior and exterior doors. Ensure that the devices record entry and trigger an alarm in the event of unauthorised access. Examples of such devices include badges or key cards, keypads, closed-circuit television and biometric scanners. 7. Conduct regular physical security awareness training.

DSS05 Process Practices, Inputs/Outputs and Activities (cont.) CHAPTER 5 COBIT 5 PROCESS REFERENCE GUIDE CONTENTS Management Practice Inputs Outputs DSS05.06 Manage sensitive documents and output devices. Establish appropriate physical safeguards, accounting practices and inventory management over sensitive IT assets, such as special forms, negotiable instruments, special-purpose printers or security tokens. From Description Description To APO03.02 Information architecture model Inventory of sensitive documents and devices Internal Access privileges Internal Activities 1. Establish procedures to govern the receipt, use, removal and disposal of special forms and output devices into, within and out of the enterprise. 2. Assign access privileges to sensitive documents and output devices based on the least-privilege principle, balancing risk and business requirements. 3. Establish an inventory of sensitive documents and output devices, and conduct regular reconciliations. 4. Establish appropriate physical safeguards over special forms and sensitive devices. 5. Destroy sensitive information and protect output devices (e.g., degaussing of electronic media, physical destruction of memory devices, making shredders or locked paper baskets available to destroy special forms and other confidential papers). Management Practice Inputs Outputs DSS05.07 Monitor the infrastructure for From Description Description To security-related events. Security event logs Internal Using intrusion detection tools, monitor the infrastructure for unauthorised access and ensure that any events are Security incident Internal integrated with general event monitoring and characteristics incident management. Security incident tickets DSS02.02 Activities 1. Log security-related events reported by infrastructure security monitoring tools, identifying the level of information to be recorded based on a consideration of risk. Retain them for an appropriate period to assist in future investigations. 2. Define and communicate the nature and characteristics of potential security-related incidents so they can be easily recognised and their impacts understood to enable a commensurate response. 3. Regularly review the event logs for potential incidents. 4. Maintain a procedure for evidence collection in line with local forensic evidence rules and ensure that all staff are made aware of the requirements. 5. Ensure that security incident tickets are created in a timely manner when monitoring identifies potential security incidents.
