Access Certification
Hitachi ID Identity Manager includes a built-in infrastructure to perform periodic certification of users and entitlements.
Access certification is a process where business stake-holders are periodically invited to review entitlements, sign-off on entitlements that appear to be reasonable and flag questionable entitlements for possible removal.
There are several components to access certification:
- Discovery:
Before entitlements can be reviewed, they have to be collected from systems and applications and mapped to users. Technical identifiers should be replaced by human-legible descriptions that reviewers will understand. Since entitlements change all the time, discovery should be a regularly scheduled, automated process, not a one-time data load.
- Who performs the reviews?
Options include managers -- asked to review their subordinates, application or data owners -- asked to review lists of users who can access their applications or data or security officers -- asked to review high risk entitlements.
- When are reviews performed?
The frequency may vary with the business risk posed by the entitlements in question.
- What kinds of entitlements are reviewed?
The highest level review is of employment status -- should the user in question still have access to any systems? Slightly more granular is a review of roles -- should the user in question still have these roles? At the lowest level of granularity are basic entitlements -- should the user in question have a login ID on this system or belong to this security group?
- Which entitlements warrant a review?
Not every entitlement poses a significant business risk. User membership in the social committee mailing list is not really worth reviewing, for example. Some determination must be made of the risk level posed by each entitlement, as this forms the basis for deciding whether to review it and how often.
- What happens to rejected entitlements?
Reviewers may flag entitlements as inappropriate, in which case something should be done. Does this raise a work order in an IT issue management system, or trigger a connector to revoke the entitlement immediately? Should further reviews take place before the entitlement is reviewed?
