I’ve written before how some periodic reviews provide management with little assurance, but management doesn’t realize how little.
My previous post focused mostly on server access￼. In this post, I want to look at normal user access.
For example, let’s assume your company has a policy that states that all IDs must be assigned within an Active Directory group. In other words, IDs are assigned to groups, and groups are assigned to assets; IDs should not be assigned directly to an asset.
Assume the control you are testing states that user access is reviewed annually.
At a company I worked at recently, I ran across a Sharepoint site and wondered whether I could download data that I wasn’t supposed to see.
Now I understand the purpose of SharePoint and company intranets is to share data, but even then, some data should be restricted to a limited number of people.
So I decided to check (before doing things like this, you better know How to Stay Out of Jail).
One of my current clients is trying really hard to do periodic access reviews.
They know that mistakes are made in granting access, that users get access and eventually don’t need it anymore, but don’t tell anyone, and that some users leave the company without their manager’s knowledge (I never have understood how that happens, but it does; it has happened in every Fortune 500 company in which I’ve worked).
When checking system access, make sure you look at all the different items that affect the user’s access. For example, the user might need one or more of the following:
- Application ID
- Application role or group
- Membership in an local server group, Active Directory (AD) group, or UNIX Group
- Access to the application’s share and/or folder on the server
- Database ID
- Database role, including access permissions (read/write)
- Other permission (from a home-grown application code or enterprise identify management system)
Since I started Quote of the Weak, I haven’t heard that many good quotes we can share a chuckle over. So, in contrast, here’s a great quote of the strong:
