The principle of least privilege (PoLP) refers to the concept that a user has the bare minimum access or permissions needed to work. For instance, when creating a user account to access database records, administrators should avoid assigning admin rights unnecessarily. Likewise, a programmer updating legacy code doesn’t need access to the company’s financial records.
PoLP represents a cybersecurity best practice that protects privileged access to a business’s high-value assets and data. This includes customer and employee records. This principle goes beyond human users. It also applies to systems, applications, and connected devices that need permissions or privileges to complete a task.
What is PoLP
The most infamous data breaches on record occurred because of a compromise of their network credentials. In all cases, hackers used privileged accounts to access critical business data and private records of customers.
- Learn from past breaches and ensure your security professionals have security strategies so users can work within the network.
- To enforce the PoLP effectively, develop a strategy to manage and secure privileged credentials centrally. Implement flexible controls that balance operational needs, user experience, compliance, and cybersecurity requirements.
PoLP offers an effective way to restrict unauthorized access to data across different layers of your security environment, including applications, users, systems, networks, databases, and processes. Grant users permission only to execute, read, or write the specific resources or files they need to do their jobs.
You can restrict access rights for devices, processes, systems and applications to privileges required to carry out authorized activities.
Managing access levels
Sometimes, systems assign privileges based on role attributes like business unit, time of day, seniority, or special conditions. Examples include:
- Least privileged user accounts. These are standard user accounts with PoLp. Under normal circumstances, most of your users should be operating under these accounts 90 to 100 percent of the time.
- Superuser accounts. These are essentially admin accounts used by specialized cybersecurity users and often come with unlimited privileges. In addition to the read/write/execute privileges, these accounts can make systemic changes in your network.
- Guest user accounts. These accounts are created on a situational basis and often have the least number of privileges, lower than those of the standard user accounts.
An interesting thing to note about many data breaches is that they begin with the hackers gaining access to millions of customer accounts through a third-party contractor who had network access and the permission to upload. What this implies is that you must not ignore third-party vendor risk management in your cybersecurity. Apart from your internal users, you must also implement the PoLP for your third-party vendors, as they can be a major security risk for your business. Limiting third-party vendor access to your critical data can be an efficient strategy for minimizing the associated risk.
What to do? Diminish the attack surface
Since PoLP restricts privilege elevations and the number of users given access to confidential information, it inherently enhances the security of your critical data
- Reduces the impact of breaches. By implementing PoLP, you can substantially reduce the impact of a breach resulting from unauthorized or unwanted use of network privileges. For instance, if a user account with limited privileges is compromised, the scope of catastrophic harm is relatively low.
- Reduces malware propagation and infection. Hackers usually target applications and systems with unrestricted privileges. As one of the most common web application cyberattacks, SQL injection attacks by inserting malicious instructions within SQL statements. The hacker can then enhance his privileges and acquire unauthorized control over your critical systems. However, by implementing PoLP, you can efficiently stunt and contain such malware attacks to where they first entered your system.
- Ensures superior data security capabilities. In addition to eliminating any security flaws on the periphery of your business, you also need to focus on minimizing the risk of proprietary data theft and insider leaks. It is imperative to monitor and control the activity of your authorized users to reinforce your cybersecurity stance.
