Question 1
Describe the administrative management practices of separation of duties, job rotation, and mandatory vacations and their role within operations security
The administration has the mandate to ensure that the organization is running as expected. It has the mandate to assign duties and tasks to various individuals. Administration management oversees the implementation of the company’s objectives. Concerning separation of duties, the administration takes the measure as an ideal strategy to avert conflict of interest or fraud. Technically, fraud may still occur due to the collision. The management creates a communication network in every department to counter fraud cases.
Similarly, job rotation can be conducted. For example, in the department that handles valuable items often rotate or conduct shift of its employees. The advancement in technology illuminates the need to perform job rotation to guarantee the effectiveness of the security systems. Further, the management can opt to implement the mandatory vacation. Often this is done to enable both the internal and external auditors to conduct their research concerning the department in question (Ahmed & Hu, 2015, p. 55). It is a security operation that employees are informed to avoid victimization or stereotyping. The need to restore confidence in an organization has led to performing regular screening, sensitization security training, change control measures and providing procedure or guidelines by publishing policies concerning security.
Question 2
Describe the different methods of RAID. What is RAIT
RAID is better known as Redundant Array of Independent Disks. It is the essence of putting physical devices together to form a RAID set. They are used when high performance is required. High tolerance of fault is sustained when RAID set is used. An array of disks is controlled adequately by use of a single set (Kim, 2015, p. 963). The desire to have a large storage volume prompted the need to design RAID.
There are different methods of RAID as indicated below
RAID 0 – It is used to obtain optimized write performance, data is put into the HDDS (Hard Disk Drives). The type has no guaranteed protection of actual data
RAID 1 – Engages the mirroring technique. Easily recoverable and it is reliable
RAID 0+1 – uses stripping and mirroring system
RAID 5- uses parity and striping technique. It is tolerated to faults. It is inexpensive. It is essential in creating backups.
RAID 6 – Used in businesses. Uses excess parity block. It is error proof.
RAID 10- It has the combination of RAID 0 and 1 (1+0). It helps in performing high write operations.
What is RAIT
"Redundant Array of Inexpensive Tapes" is used when performing error recovery. Using various tape drives, data can be stripped via one drive.
