9.1.6 Local enterprise security design

Example Corp. decides on the following security design to protect its directory data:

•They create an ACI that allows employees to modify their own entries.

Users can modify all attributes except the uid, manager and department attributes.

•To protect the privacy of employee data, they create an ACI that allows only the employee and their manager to see the employee's home address and phone number.

•They create an ACI at the root of the directory tree that allows the two administrator groups the appropriate directory permissions.

The directory administrators group needs full access to the directory. The messaging administrators group needs write and delete access to the mailRecipient and mailGroup object classes and the attributes contained on those object classes, as well as the mail attribute. Example Corp. also grants the messaging administrators group write, delete, and add permissions to the group subdirectory for creation of mail groups.

•They create a general ACI at the root of the directory tree that allows anonymous access for read, search, and compare access.

This ACI denies anonymous write access to password information.

•To protect the server from denial of service attacks and inappropriate use, they set resource limits based on the DN used by directory clients to bind.

Example Corp. allows anonymous users to receive 100 entries at a time in response to search requests, messaging administrative users to receive 1,000 entries, and directory administrators to receive an unlimited number of entries.

For more information about setting resource limits based on the bind DN, refer to the "User Account Management" chapter in the HP-UX Directory Server administrator guide.

•They create a password policy which specifies that passwords must be at least eight characters in length and expire after 90 days.

For more information about password policies, see “Designing a password policy”.

•They create an ACI that gives members of the accounting role access to all payroll information.
