How can access to SPS be restricted by system-level IP restrictions?
Various mechanisms external to SPS can be used to restrict administrative access. For example, SPS could be installed on a dedicated Web server, listening at a specific port; access to this port could be restricted by a router, firewall, or Web server configuration. Are there MD5 signatures for SPS? Yes. MD5 signatures are available for the distribution itself, as well as for each file. Signatures for each version can be downloaded from the main SPS distribution site.
