By courtesy of SSRT/Digital Equipment we received the following information on
how to deal with SATAN/SANTA on Digital's Ultrix, OpenVMS (UCX), DEC OSF/1 and
Digital's Firewall Product.

The information is not very explicit. We present it anyway to enable you to
see Digital's view on the subject.

In addition to this advisory we strongly recommend you to read the CERT-NL

     Dear Valued Digital Customer,

     Subj:   ULTRIX, OpenVMS (UCX), DEC OSF/1  and Digital's Firewall Product


     DESCRIPTION: 
     -------------------------------------------------------------------------

     SATAN is a testing and reporting tool that collects a variety of
     information about networked hosts. SATAN gathers information about
     specified hosts and networks by examining network services (for example,
     finger, NFS, NIS, and ftp). In addition to reporting potential
     vulnerabilities, SATAN gathers general network information (network
     topology, network services run, types of hardware and software being used
     on the network).  


     The advisories, the documentation contained in the SATAN package, or the 
     related news stories, do not  disclose any previously unknown computer
     system security vulnerabilities and does not pose a threat to Digital
     Equipment Operating Systems properly maintained (with a Security
     Baseline), with the latest software releases and with subsequent release
     patches installed. The reported methods of probing have been known for a
     number of years and corrected through ECO (patch release) and subsequent
     releases of the operating systems.
                 
     These SATAN probes may be monitored by a number of techniques, only 
     some of which are addressed in the CERT Advisory and subsequent articles.
     A more complete analysis of the general problem has been conducted 
     by firewall experts in Digital's Palo Alto and Galway, Ireland, 
     research labs and product groups. No vulnerabilities where discovered 
     in properly configured environments.

     For information to monitor your site for SATAN probes, using
     the proper combination of Digital products, configured in the optimal
     manner please contact your normal Digital support channel.

     Digital Equipment Corporation does not intend to distribute Satan nor does
     it plan any an advisory containing kit location, testing results or 
     redistribution of any advisories containing that information.

     Digital Equipment Corporation recommends that this Software be treated
     with all the due care necessary based on the current publicly available
     information or advisories and make an informed decision prior to any
     installation, or use, within their environment and to use all available
     security monitoring techniques to guard against a potential malicious 
     probe of SATAN to their environment.

     GENERAL INFORMATION
     ---------------------------------------------------------------------

     SATAN was designed as a security tool for system and network
     administrators for security analysis. However, given its potential wide
     distribution, ease of use, and ability to scan remote networks, SATAN is
     also likely to be used to locate vulnerable hosts for malicious reasons.
     It is also possible that sites running SATAN for a legitimate purpose will
     accidentally scan your systems/environment via SATAN's exploratory mode.

     As always, Digital recommends that you regularly review your system
     management and security procedures.  Digital will continue to review
     and enhance security features, and work with our customers to further
     improve the integrity of their systems.
