SY0-501 : CompTIA Security+ Certification​​ : Part 09

  1. An administrator is configuring access to information located on a network file server named “Bowman”. The files are located in a folder named “BalkFiles”. The files are only for use by the “Matthews” division and should be read-only. The security policy requires permissions for shares to be managed at the file system layer and also requires those permissions to be set according to a least privilege model. Security policy for this data type also dictates that administrator-level accounts on the system have full access to the files.

    The administrator configures the file share according to the following table:

    SY0-501 Part 09 Q08 031 Answer
    SY0-501 Part 09 Q08 031 Answer

    Explanation:
    RAID-0 is known as striping. It is not a fault tolerant solution but does improve disk performance for read/write operations. Striping requires a minimum of two disks and does not use parity.
    RAID-0 can be used where performance is required over fault tolerance, such as a media streaming server.
    RAID-1 is known as mirroring because the same data is written to two disks so that the two disks have identical data. This is a fault tolerant solution that halves the storage space. A minimum of two disks are used in mirroring and does not use parity. RAID-1 can be used where fault tolerance is required over performance, such as on an authentication server. RAID-5 is a fault tolerant solution that uses parity and striping. A minimum of three disks are required for RAID-5 with one disk’s worth of space being used for parity information. However, the parity information is distributed across all the disks. RAID-5 can recover from a sing disk failure.
    RAID-6 is a fault tolerant solution that uses dual parity and striping. A minimum of four disks are required for RAID-6. Dual parity allows RAID-6 to recover from the simultaneous failure of up to two disks. Critical data should be stored on a RAID-6 system.
  9. A security administrator is trying to encrypt communication. For which of the following reasons should administrator take advantage of the Subject Alternative Name (SAM) attribute of a certificate?

    • It can protect multiple domains
    • It provides extended site validation
    • It does not require a trusted certificate authority
    • It protects unlimited subdomains
  10. After a merger between two companies a security analyst has been asked to ensure that the organization’s systems are secured against infiltration by any former employees that were terminated during the transition.

  19. A security administrator returning from a short vacation receives an account lock-out message when attempting to log into the computer. After getting the account unlocked the security administrator immediately notices a large amount of emails alerts pertaining to several different user accounts being locked out during the past three days. The security administrator uses system logs to determine that the lock-outs were due to a brute force attack on all accounts that has been previously logged into that machine.

    Which of the following can be implemented to reduce the likelihood of this attack going undetected?

    • Password complexity rules
    • Continuous monitoring
    • User access reviews
    • Account lockout policies
  20. A bank requires tellers to get manager approval when a customer wants to open a new account. A recent audit shows that there have been four cases in the previous year where tellers opened accounts without management approval. The bank president thought separation of duties would prevent this from happening.

    In order to implement a true separation of duties approach the bank could:

    • Require the use of two different passwords held by two different individuals to open an account
    • Administer account creation on a role based access control approach
    • Require all new accounts to be handled by someone else other than a teller since they have different duties
    • Administer account creation on a rule based access control approach
