Access Control/Authentication Management

Symark's product suite makes integration a whole lot simpler.

If you need to make a table leg out of a block of wood, you have two options: You can either spend weeks working on it with a chisel, hammer and other assorted tools -- or you can clamp the block in a lathe and turn out a leg in a matter of minutes.

In the world of integration, Symark's ( suite of tools is the lathe, letting you accomplish in minutes what would otherwise take considerably longer.

Symark's solutions include:

  • PowerADvantage: The newest of all the Symark products, this one extends Active Directory functionality to Unix and Linux systems. This is a good solution to use when your site is primarily Windows-based and running only a few *Nix machines.

  • PowerBroker: This tool makes it possible to give users root-level access without sharing the root password. By adding additional granularity, administrators can delegate tasks such as backups without risking the harm that can often accompany elevated user privileges. The granularity that can be used for user accounts can also extend to directories and files.

  • PowerKeeper: Now in Version 2.0, PowerKeeper is an appliance-based product for privileged/root account and password management. It can manage the creation, control, storage and retrieval of account passwords in Unix, Linux and Windows systems. It makes single-factor authentication possible using Active Directory or LDAP, and implements FIPS 140-2 level encryption. Some of its other features include performance monitoring and enhanced logging.

  • PowerPassword: Intended to let a help desk delegate specific account-management tasks, PowerPassword allows you to create policies that govern authentication and usage of SSH, FTP, su, telnet, rlogin and others. As with the other Symark tools, detailed logging/auditing is possible and the default.

While there are some differences between each of the products, in general you'll find that supported *Nix versions tend to include HP-UX, IBM AIX, Red Hat, Solaris and SUSE. Supported Windows versions are typically Windows Server 200x and XP.

All the products from Symark can be downloaded for a 30-day trial. I encourage you to visit the company's site, look at the screenshots, read the FAQ and see if you don't agree that the solutions offered can simplify your tasks substantially.
