Just-in-time (JIT) addresses the problem of excessive privilege by assigning elevated privileges on a limited, as-needed basis. This eliminates accounts with standing, elevated privileges on corporate systems.<\/p>\n\n

Many cyberattacks involve compromised privileged accounts, which attackers target to take advantage of their increased access. JIT access helps to eliminate this risk by reducing the access that an account has and aligning access management with the principle of least privilege and the zero trust security model.<\/p>\n\n

Why Just-in-Time Access Matters<\/h2>\n\n

Overprovisioned accounts are a common challenge for enterprise security. Most cyberattacks involve attackers gaining access to a privileged account, then leveraging the associated privileges to achieve their goals. When users are assigned privileges that they don\u2019t need – or don\u2019t always need – this expands the range of accounts that an attacker can target.<\/p>\n\n

JIT access is important because it helps to reduce the risk associated with privileged accounts. Instead of allowing standing, \u201calways on\u201d privileges, JIT offers access on an as-needed basis. This allows privileged access to be turned off by default and only activated after a risk review is completed.<\/p>\n\n

JIT access is also important for compliance with regulatory requirements and corporate zero trust programs. Overprovisioned accounts may violate requirements to control access to protected data and increase an organization\u2019s risk of a reportable data breach.<\/p>\n\n

Core Components of Just-in-Time Access<\/h2>\n\n

JIT access is implemented using a combination of temporary privileges managed via automated context-aware policies and provisioning\/deprovisioning. Additionally, these policies must be supported by security controls to ensure that access can be granted as needed while eliminating the risk of access control bypasses.<\/p>\n\n

Temporary Privileges<\/h3>\n\n

JIT access replaces standing privileges with temporary, time-bound ones. Instead of permanent access, an account has access for a certain amount of time or the length of a particular session. This is well-suited to admin tasks, third-party vendor access, and other scenarios where certain privileges are only needed intermittently.<\/p>\n\n

This reduces the impact of a compromised account by decreasing the amount of damage that can be done with it. If access is denied or expires, the attacker lacks the privileged access, unlike with \u201calways on\u201d privileges.\u00a0<\/p>\n\n

Context-Aware Policies<\/h3>\n\n

JIT access differs from persistent privileges because access is granted on an as-needed basis. However, for this to be a useful distinction, the system needs a means of determining whether an access request is legitimate.<\/p>\n\n

JIT access uses contextual information (user, device, location, and other risk signals) to define a risk score for a request, which is used to determine whether the request should be granted or if additional authentication is needed. Policies can also be denied to always block access under certain scenarios, such as access requests outside of business hours or from unknown devices.<\/p>\n\n

Automated Provisioning and Deprovisioning<\/h3>\n\n

After an access decision is made, privileges need to be provisioned to the account and deprovisioned at the end of the time window or session. Automation is critical to doing so without negatively impacting normal business.<\/p>\n\n

With automation, JIT access reduces IT overhead and enhances security posture. Automatic deprovisioning eliminates the risk that privileges remain at the end of a user session. Additionally, logging and auditing of all access decisions and actions enhances visibility and simplifies compliance.<\/p>\n\n

How Just-in-Time Access Works in Practice<\/h2>\n\n

In practice, JIT access is an automated process that should be largely invisible to the user. For example, consider the case where a contractor needs access to corporate resources for two hours to complete a task.\u00a0<\/p>\n\n

This would look something like the following:<\/p>\n\n
