    • Install the latest antivirus definitions
    • Deploy a network-based IPS
  2. An information security manager conducted a gap analysis, which revealed a 75% implementation of security controls for high-risk vulnerabilities, 90% for medium vulnerabilities, and 10% for low-risk vulnerabilities. To create a road map to close the identified gaps, the assurance team reviewed the likelihood of exploitation of each vulnerability and the business impact of each associated control.

    • KPI
    • KRI
    • GRC

    • Issue tracker
    • Static code analyzer
    • Source code repository
    • Fuzzing utility
  4. A legacy web application, which is being used by a hospital, cannot be upgraded for 12 months.

  11. A security assessor is working with an organization to review the policies and procedures associated with managing the organization’s virtual infrastructure. During a review of the virtual environment, the assessor determines the organization is using servers to provide more than one primary function, which violates a regulatory requirement. The assessor reviews hardening guides and determines policy allows for this configuration. It would be MOST appropriate for the assessor to advise the organization to:

    • segment dual-purpose systems on a hardened network segment with no external access
    • assess the risks associated with accepting non-compliance with regulatory requirements
    • update system implementation procedures to comply with regulations
    • review regulatory requirements and implement new policies on any newly provisioned servers
  12. While conducting a BIA for a proposed acquisition, the IT integration team found that both companies outsource CRM services to competing and incompatible third-party cloud services. The decision has been made to bring the CRM service in-house, and the IT team has chosen a future solution. With which of the following should the Chief Information Security Officer (CISO) be MOST concerned? (Choose two.)

    • Data remnants
    • Sovereignty
    • Compatible services
