Least privilege: give only what is needed, nothing more
The principle of least privilege means granting each user, application, or system only the rights strictly necessary to perform its task — nothing more, and not "just in case".
Definition
This principle is simple to state but often difficult to apply over time: a right granted temporarily for a one-off project and never removed afterwards, or an administrator account used daily for convenience rather than only for tasks that truly justify it.
Its value is direct: if an account or application is compromised, the damage remains limited to the rights actually granted. An account with minimal privileges mechanically limits what an attacker can do, even after gaining initial access.
Key points
Strictly necessary rights
Each granted access right must correspond to a real and current need, not to a hypothetical future convenience.
An essential periodic review
Without regular review, accumulated rights almost always exceed the real need over time.
Limited impact in case of compromise
An account with minimal privileges mechanically reduces what an attacker can do once inside.
How BCIT can support you
Reviewing rights and privileges is a central part of our audits, especially in Active Directory.
Questions fréquentes
How can least privilege be applied without blocking teams?
By granting temporary and reviewable rights rather than permanent ones, with a simple request process for one-off needs.
How often should access rights be reviewed?
A review at least every six months, and systematically whenever a role changes or someone leaves, limits the accumulation of unnecessary privileges.
