Appendix B: Security Considerations
The SLM provides data path security by means of SSH, Web/SSL, and in the case of SLCs,
secure channel. Even with the use of these protocols, however, do not assume you have complete
security. Securing the data path is only one measure needed to ensure security. This appendix
briefly discusses some important security considerations.
Security Practice
Develop and document a Security Practice. The Security Practice should state:
The dos and don'ts of maintaining security. For example, the power of SSH and SSL is
compromised if users leave sessions open or advertise their password.
The assumptions that users can make about the facility and network infrastructure, for
example, how vulnerable the CAT 5 wiring is to tapping.
Factors Affecting Security
External factors affect the security provided by the SLM, for example:
A terminal to the SLM may be secure, but the path from the SLM to the end device may not be
secure.
With the right tools, a person having physical access to open the SLM may be able to read the
encryption keys.
There is no true test for a denial-of-service attack-there is always a legitimate scenario for a
request storm. A denial-of-service filter locks out some high-performance automated/scripted
requests. The SLM attempts to service all requests and does not filter out potential denial-of-
service attacks.
Available Services and Port Numbers
The SLM supports the services listed below. When installing and configuring an SLM in an
environment where such services are limited, please make sure network equipment configurations
allow access to and from the listed port numbers.
