Some Important Security Concepts

Introduction

This section will particularly focus on a few substantial security concepts such as job rotation, least privileges, and separation of duty.

Some Important Security Concepts

Job rotation: It is a form of work where employees have to rotate their job roles and have to be specialized or trained to perform more than one type of job. From a security standpoint, job rotation is crucial in avoiding theft or fraudulent activities at work, which could damage the company in terms of brand image or leak of private data. As everyone is specialized in the majority of the job roles, nobody has complete power and grasp on the knowledge it gets shared equally, thus restricting employees to have substantial power at work.

Least privileges: The principle of least privileges ( PoLP) is a technique corporations use to give business users (employees)  the bare minimum level of access and authority on their computers, adequate for completing their day-to-day tasks only. This is also known as privilege creep. IT admins considered such measures as cybersecurity best practices as providing fewer rights reduces access to the majority of private corporate data and, thus, fewer chances for any security breach.

Separation of duty: This concept is similar to job rotation. Separation of duties plays a crucial role in internal controls and is an expensive form of data protection. It involves dividing one job into different parts and allotting those to separate employees. This avoids any conflict of interest and restricts the flow of information between employees, and without proper information and communication, the chances of fraud become negligible.

Real life Example of Security Concepts (Use case)

Job rotation: If employees were working in one job for an extended period, they might feel discouraged and bored or even long for recognition by their supervisor. In such a situation, they often tend to carry out fraudulent activities as they become more tempted to do something different from their daily routine and set policies.

Least privileged: Employees 1 and 2 working in different roles have access to a different set of software and data packages that are enough for them to perform their daily jobs. If they need something extra, they may have to contact the IT head.

Separation of duty: In making a cash flow sheet, one person calculates the accounts payable, and the other calculates the accounts receivable. Both employees have their duties and are not aware of any other jobs.

Advantages of the Security Concepts

Job rotation:

  • Avoids boredom at work
  • Everyone has equally divided power and thus fewer chances of fraud occurrence

Least privileged:

  • Reduces potential access for any cyberattack
  • Improves communication and productivity, as everyone is allotted adequate knowledge and information needed to complete their work

Separation of duty:

  • Internal controls are centralized, thus reduces any confusion regarding delegation of work
  • Saves resources and time by avoiding duplication of work as every business employee will have a different duty to perform.
