When zero standing privilege is implemented, users no longer have access to administrator rights or privileges to any resources. Zero standing privilege and just-in-time access (JIT) One example is that Microsoft prefers the term zero standing access to describe applying PAM in MS Office 365 solutions since it is more holistic. Conceptually, zero standing privilege only covers the privilege granting process. Zero standing access or zero standing privilege?Īlthough these terms are used interchangeably, zero standing access covers the whole access process (login, authorization, auditing, etc.), not just zero standing privilege. So our comparison of zero-standing privilege and principles of least privilege applies here as well. Just enough access is a synonym for applying the principle of least privilege to users with just the required privileges. Zero standing privilege and just enough access Instead, each required privilege should be granted just at the time of access and be revoked once access is completed. As such, users should not be granted or pre-assigned with any privilege at all. On the other hand, zero standing privilege suggests that even the least amount of privilege has a risk of getting compromised or misused by malicious insiders or external adversaries. The principle of least privilege states that users should only be allowed the minimum permissions to perform specific tasks. Zero standing privilege and principles of least privilege Let’s explore how zero standing privilege compares with the concepts mentioned above. But there are also many other concepts related to privilege management that circle around in the PAM ecosystem, such as the principle of least privilege, just-in-time access, just enough access, etc. Zero standing privilege is an essential feature of a modern PAM solution. Zero standing privilege in a modern privileged access management solution Zero standing privilege makes it much more difficult for attackers to explore privilege escalation vulnerabilities since a core tenant of ZSP is that privileges should only be assigned during the time of access and revoked once the reason for access is addressed. It buys them more time to explore ways to escalate privilege even when the least possible privileges are applied. Accounting for an average time of 287 days to identify a data breach, the opportunity window for attackers to misuse compromised privileged accounts or stolen credentials is huge. It is known that credential compromises, privilege misuse, and insider threats pose significant risks to organizations.Įven when the principle of least privilege is followed, attackers can find a way to escalate privileges since by definition, at least some standing privilege has been assigned. And 57% of database breaches involved insider threats. Importance of zero standing privilegeĪccording to the Verizon insider threat report 2019, 20% of cybersecurity incidents result from privilege misuse.
ZSP significantly reduces the risks of privilege abuse and privilege compromise. ZSP applies the same concept to access controls and mandates that users' privileges only be assigned during the time of access and not by default. Zero-trust security forbids authorization based on static predefined trust boundaries. In practice, it implies no users should be pre-assigned with administrative account privileges.
The term zero standing privilege was coined by an analyst at Gartner. Zero standing privilege (ZSP) is an applied zero trust security strategy for privileged access management (PAM).
