  11. Which initial step should be followed when a security breach is found on a corporate system?
    • Create a drive image of the system.
    • Isolate the infected system.*
    • Establish a chain of custody.
    • Photograph the system.
    If a security breach occurs, it is necessary to follow the proper procedures.
    The infected system should be isolated immediately.
    A drive image should be taken before working with data on the hard drive of the infected system.
    After data is collected but before equipment is disconnected, there should be photographs taken of the equipment before anything else should be done.
    A chain of custody should be established identifying all evidence.
  12. Which security test is appropriate for detecting system weaknesses such as misconfiguration, default passwords, and potential DoS targets?
    • vulnerability scanning*
    • network scanning
    • integrity checkers
    • penetration testing
    There are many tests used to assess the operational status of networks and systems. Weaknesses in systems such as blank or default passwords, or misconfigurations that would make a system a target of a DoS attack can be detected through vulnerability scanning.
  13. How does network scanning help assess operations security?
    • It can simulate attacks from malicious sources.
    • It can log abnormal activity.
    • It can detect open TCP ports on network systems.*
    • It can detect weak or blank passwords.
    Network scanning can help a network administrator strengthen the security of the network and systems by identifying open TCP and UDP ports that could be targets of an attack.
  14. What is the objective of the governing policy in the security policy hierarchy structure?

    • It provides general policies on how the technical staff should perform security functions.
    • It defines system and issue-specific policies that describe what the technical staff does.
    A security policy is often broken up into a hierarchical structure consisting of three sub-policies:
    a governing policy
    a technical policy
    an end-user policy
    The governing policy is a high-level policy that provides security guidelines for the entire company and outlines overall security goals.
  15. What step should be taken after data is collected, but before equipment is disconnected, if a security breach is found on a system?
    • Create a drive image of the system.
    • Isolate the infected system.
    • Photograph the system.*
    • Determine if data tampering has occurred.
    If a security breach occurs, it is necessary to follow the proper procedures.
    The infected system should be insolated immediately.
    A drive image should be taken before working with data on the hard drive of the infected system.
    After data is collected but before equipment is disconnected, there should be photographs taken of the equipment before anything else is done.
  16. Which security program is aimed at all levels of an organization, including end users and executive staff?
