  8. Six months into development, the core team assigned to implement a new internal piece of software must convene to discuss a new requirement with the stake holders. A stakeholder identified a missing feature critical to the organization, which must be implemented. The team needs to validate the feasibility of the newly introduced requirement and ensure it does not introduce new vulnerabilities to the software and other applications that will integrate with it.

    Which of the following BEST describes what the company?

    • The system integration phase of the SDLC
    • The system analysis phase of SSDSLC 
    • The system design phase of the SDLC

  9. A company is investigating a data compromise where data exfiltration occurred. Prior to the investigation, the supervisor terminates an employee as a result of the suspected data loss. During the investigation, the supervisor is absent for the interview, and little evidence can be provided form the role-based authentication system in use by the company.

    The situation can be identified for future mitigation as which of the following?

    • Job rotation
    • Log failure
    • Lack of training
    • Insider threat
  10. A security administrator needs an external vendor to correct an urgent issue with an organization’s physical access control system (PACS). The PACS does not currently have internet access because it is running a legacy operation system.

    Which of the following methods should the security administrator select the best balances security and efficiency?

    • Temporarily permit outbound internet access for the pacs so desktop sharing can be set up 
    • Have the external vendor come onsite and provide access to the PACS directly
    • Set up VPN concentrator for the vendor and restrict access to the PACS using desktop sharing
    • Set up a web conference on the administrator’s pc; then remotely connect to the pacs
  11. A datacenter manager has been asked to prioritize critical system recovery priorities.

    Which of the following is the MOST critical for immediate recovery?

    • Communications software
    • Operating system software 
    • Weekly summary reports to management
