Impact of the principle of least privilege on data security
The least privilege principle (POLP) mainly denotes the access of users for a limited period. Within an IT environment, this principle is effective because the attackers can be denied access to critical systems (Krohn et al., 2005). The chances of data theft and breaches reduce as well. The users will be given only the required information. The given information would be enough for performing the job duties and responsibilities. In an organization, data security should be prioritized, and the principle of least privilege is an appropriate way of reducing the attacks and risks from cyber attackers.
Discussion regarding the principle
The principle is used by network managers so that they can secure the critical infrastructure of the company. The network systems are vulnerable, and POLP restricts the privileges of the users. Business growth, along with business flexibility, can be ensured. Often users do not require exposure to certain systems and might create a problematic situation. Hence, application of POLP ensures fewer liabilities. The users are not given excessive permissions, and POLP also provides the chances of the least number of errors. This, in turn, enhances the network performance of the organization.
When users are given minimum permissions to access processes, applications, and systems, they are most likely to act under an authority. Role-based privileges are given to users. The considerations are seniority, location, and special circumstances (Sattarova Feruza & Kim, 2007). The administrators are supposed to set different settings for privileged and non-privileged users. For instance, the superuser has more privileges than a public user. The superuser has been given the privilege to modify file settings, creation of software, and delete the data. LPU refers to the least privilege users, and they do not manage any network resources or administer systems.
An outline of the impact of the principle
POLP is used for securing the IT infrastructure of the company. Over the years, it has managed to become a vital security policy. Enterprises enforce POLP to protect the functionality and data of the network systems. The malicious behavior of attackers can be stopped. Data security can be enhanced, as well. An example can be considered. An HR is supposed to have access to the database of enterprise payroll; however, the employee does not need to have access to the client database of the enterprise. Similarly, a sales department worker require access to the database of the clients, however, he or she does not require access to the database of payroll. In this manner, the security of the enterprise can be enhanced.
Moreover, the principle surely helps in reducing security related risks by minimizing the number of disruptions. The entrance or pathways of the enterprise can be secured by applying this principle. Malware-related infection can be reduced, and hackers would not be able to install code and steal passwords (Schneider, 2003). Once malware attacks the system, it would be difficult to retrieve the data; therefore, the application of POLP is a necessity in enterprises. Limited access to users would ensure limited errors and issues.
