How Does Least Privilege Principle Help With User Access Management

Information protection is a multifaceted, dynamic discipline based on several fundamental concepts. The three most significant are considered the priorities of any information management system: privacy, integrity, and accessibility.

How can the concept of least privilege help your business manage user access for better protection? Find out the answer to this question and a lot more about the same in this blog. 

Understand the Working of the Principle of Least Privilege  

The concept of the least privilege principle works by providing only the amount of access necessary to complete the task at hand. The maxim of least privilege decreases the possibility of attackers getting access to vital infrastructure or confidential data in an IT setting by breaching a low-level user profile, software, or program. Implementing the POLP helps keep compromises confined, preventing them from expanding across the system.

Learn With Some Examples

Every stage of a system will benefit from the concept of least privilege. End users, programs, structures, networks, libraries, software, and other IT ecosystem aspects are included. Here are a few instances of how the theory should be used in reality (and when it might fail).

MySQL Accounts

When several different identities are used to execute various roles in a MySQL system, the concept of least privilege is enforced. You should use a MySQL account with only sorting rights with an online form that allows users to filter results. An intruder that takes advantage of the form would only be able to filter data. If the account is granted the ability to delete information, the attacker may get complete control of the database.

User Account

According to the concept of least privilege, an individual whose duty is to enter data into the database only requires the right to introduce records to the database. The malicious assault is limited to allowing database entries if ransomware infects the employee’s device or if the employee opens a link in a phishers email. However, if the employee has root access, the virus will spread across the whole system.

Benefits of Using POLP

There are many advantages of implementing the principle of least privilege. Here are a few of them.

Better Security

Since he had admin rights, Edward Snowden uncovered millions of NSA archives, despite his highest-level task being database backups. After the Snowden breach, the NSA has used the concept of least privilege to strip 90 percent of its staff of higher-level authority.

Stops Malware Spread

Since malware (such as SQL injections or spyware) should be refused the right to escalate processes that enable it to mount or execute, the least privilege helps significantly reduce malware infection and spread.

Better System Stability

It’s simpler to evaluate the code’s potential behavior and relationships with other programs because the scope of improvements it may make to a device is limited. In reality, systems with limited privileges, for example, would not be able to execute operations that may cause a server to fail or have a detrimental impact on any applications on the same device.

Enhanced Security

When the code is restricted in its ability to execute activities on behalf of the whole device, flaws in one system cannot be exploited to hack the rest of the application. Running in standard user mode provides users with better security against unintended system-level harm caused by malicious attacks and ransomware. 

Streamlining Compliance and Audits

To discourage malicious or accidental harm to sensitive infrastructure, specific organizational protocols and legal standards compel companies to apply the concept of least privilege to privileged accounts. With a complete audit trail of privileged practices, least privilege enforcement helps companies in ensuring conformity.

Audit Readiness Improvement

When a framework is designed around the concept of least privilege, it can drastically minimize the complexity of an investigation. Furthermore, several traditional regulations include POLP enforcement as a condition of compliance.

Offers Better Stability

In addition to security, the concept of least privilege helps maintain device integrity by restricting the impact of modifications to the area in which they are made.

Ensures End-User Productivity

Removing local administrator privileges from business users reduces risk, but allowing just-in-time privilege elevation-dependent on policy keeps users active and reduces IT helpdesk calls.

Summing Up

A fundamental element of zero trust systems is the concept of least privilege. Zero Trust requires that companies check something attempting to bind to networks before providing access. It is based on the assumption that businesses do not immediately trust anything within or beyond their perimeters. Many companies move from conventional perimeter management approaches to the Zero Trust paradigm to secure their most vulnerable networks. You may also follow the suite.
