(part 1 of my series of articles on ) The Principle of Least Privilege (POLP) The first security principle that I am going to discuss is one that most System Administrators are familiar with: the “principle of least privilege” (short: POLP). It demands that the required permissions for a task shall only grant access to the needed information or resources that a task requires. When permissions are granted, we shall grant the least privileges possible. POLP is so crucial because initially it is the privileges that any attacker is targeting. When developing an application, using a least-privileged user account (LUA) is the first rule of engagement. Note User Account Control (UAC) in Windows is a feature that Microsoft developed to assist administrators in working with least-privileges by default and elevate to higher permission only when needed. You may also know that Microsoft recommends separating service accounts. This security best practice is generally referred to as service account isolation and is related to POLP: Using distinct service accounts prevents increased privileges, which happens easily when you share an account to be used for multiple purposes and as a consequence, the privileges are merged. - This would violate the principle of least privilege. Both POLP and service account isolation help reducing the attack surface (aka attack surface reduction). - Read more on this topic here: and here: Service account isolation also prevents lateral movement between serv...

Safeguarding sensitive data and protecting critical systems are paramount. One crucial practice that organizations must adopt is the principle of least privilege. By granting users only the minimum access necessary for their tasks, this approach minimizes the attack surface, reduces human error, and mitigates the impact of potential breaches. Reducing Attack Surface Least privilege significantly reduces the attack surface for potential threats. By limiting user privileges to the bare minimum required for their roles, the exposure to malicious activities is diminished. Attackers’ ability to escalate privileges and gain access to more data and systems is severely diminished, limiting the scope and impact of breaches. A smaller attack surface means fewer opportunities for hackers to exploit vulnerabilities and gain unauthorized access to critical assets. Minimizing Human Error Even well-intentioned employees can unintentionally cause security incidents. Adhering to the principle of least privilege minimizes the potential damage resulting from human error. By granting users only the necessary permissions, accidental or unauthorized changes to sensitive data or critical systems are restricted. This approach ensures effective task performance while mitigating the risk of unintentional actions that could compromise security. Containing Breaches and Limiting Lateral Movement In the event of a breach, least privilege aids in containing the impact. By restricting user access, organi...

The principle of least privilege is a security concept that recommends that any user of the system be given the minimum levels of access needed to perform their duties. This principle is considered one of cybersecurity best practices and it's applied when there's a need to protect a high-value company's information or assets. The least privilege is also known as the least authority or minimal privilege. It limits the potential damage that can be brought about by unsanctioned activities, whether intentional or unintentional. The How Does The Principle Of Least Privilege Works? The minimum authority privilege works by allowing users minimal access to only perform the required job. As earlier noted, implementing the least privilege reduces the risk of system attackers gaining access to the company's security-critical information. The minimal authority privilege can be applied in all levels of the computing system, and it extends beyond human access. It can also be applied to systems and connected devices that require permissions to do a particular job. What Are The Benefits Of The Principle Of Least Privilege? The principle of least privilege has several benefits. Some of these benefits are explained here below. 1. Helps Deal With Cybersecurity Attacks While advancements in technology have come with a lot of benefits, it also has its challenges. 2. Creates An Environment With Fewer Liabilities In some cases, a user might accidentally access a critical area of the network caus...

A comprehensive guide to the security world’s most sought and least achieved goal. What does least privilege mean? In theory, the principle of least privilege is simple. It is: "The principle that a security architecture is designed so that each entity is granted the minimum system resources and authorizations needed to perform its function." [NIST] Applied to identities, the principle of least privilege means that each identity (including both humans and machine identities) should only have the permissions it needs to do its work, and no more. Applied effectively, the principle of least privilege promises to protect you from the worst consequences of a compromised identity. For example, if a hacker successfully phishes an employee, the damage they can cause is limited by that employee’s permissions to key apps and data. The fewer permissions they have, the smaller the “blast radius” from an attack. While least privilege sounds simple enough, applying it in the real world is complicated, and getting harder all the time, as the scale and complexity of hybrid- and multi-cloud deployments increases. In practice, a “perfect” implementation of least privilege isn’t possible. That would mean that no identity ever possessed permissions it didn’t strictly need for any amount of time, which isn’t realistic for any growing business. Be wary of any CISO who claims, “Mission accomplished!” It’s best to think of least privilege as an ideal to strive for. You’ll never get it perfect, bu...

It all starts with a PDF attachment. An employee doesn’t detect the signs of a The Principle of Least Privilege Means Minimal Trust The Minimal trust describes the concept of providing the least privilege possible to get the job done. It’s a risk-based model for IAM that requires a dynamic approach to security, privacy and privilege. The benefits of privileged access management are obvious, but implementing the idea will require some work. The Overprivileged Account Epidemic How bad is the crisis of overprivilege, anyway? One study from Centrify found that 72 percent of enterprises know they struggle to control excessive admin accounts, but the actual figure is likely higher. Experts estimate up to 99 percent of user privileges are unused and represent points of failure, according to And humans aren’t the only privileged users in the enterprise. “Identity” extends to anything that can access secure resources, including service accounts and APIs. MIS Training Institute noted that users represent just one-seventh of an enterprise’s identities. There’s an epidemic of issues concerning privileged access management among human users, but that’s just the tip of the iceberg. Putting the Principle of Least Privilege to Work The principle of least privilege isn’t a formula. Minimal trust is a concept, and it’s a moving target. Any efforts to mitigate Putting the least privilege principle into practice means finding the perfect balance between user trust, privacy and security across...
