ccna certification cost in kolkata.The first approach is called the two-personcontrolprinciple. This ~*principle states that two people are needed for each task, each responsible for reviewing and approving the work of the other. In addition to providing accountability and reducing the incidence of fraud, this principle can reduce errors in configuration. Because of the overhead involved, this approach is usually limited to sensitive positions that are considered to be potential security risks. Another approach to implementing SoD is the two-operator principle. This principle breaks down a task, with each part of the task being assigned to a different individual. The entire task is completed only when both parties have completed their parts. An example of the two-operator principle is a check that requires two signatures to be accepted by the bank.10.3.2.2 Rotation of dutiesDuty rotation or job rotation is a safety strategy in which each person is assigned one task and after a period of time is changed to another task. To successfully implement this principle, it is important that individuals have the necessary training to perform multiple tasks.Peer review is built into the duty rotation approach. For example, suppose a job rotation program provides for five individuals to rotate through five different roles over the course of a week. Peer review of the job occurs whether it is intended or not. When there are 5 people doing the same job during the week, each person is effectively reviewing the work of the others.In addition to providing security, rotating responsibilities helps prevent boredom from setting in, as well as giving everyone a fuller picture of how the entire network works. This can create a strong and flexible operations department because each person is capable of doing multiple jobs.10.3.2.3 Trustworthy RecoveryOne of the easiest ways to compromise a system is to have it reboot and gain control of it before all of its defenses are loaded. With this in mind, trusted recovery is an important principle of operational security. This principle states that the system will fail at some point, so a recovery process must be established. The most common way to be prepared for failure is to back up your data on a regular basis.Backing up data is a standard practice in most IT departments. Many backup software programs use accounts that bypass the security of the files. As a result, individuals who are entitled to back up data are able to access files that they would not normally be able to ask for. The same holds true for individuals who have the right to restore data.Security professionals recommend that a secure backup program include the methods listed below.
