Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.8.x
Websense software relies on the following external resources and network characteristics to function properly in your network.
*
TCP/IP
Websense software provides policy enforcement in TCP/IP-based networks only.
*
DNS server
A DNS server is used to resolve requested URLs to an IP address. Network Agent, Content Gateway, or your third-party integration product requires efficient DNS performance. DNS servers should be fast enough to support Websense policy enforcement without becoming overloaded.
*
Directory services
If Websense software is configured to apply user- and group-based policies, User Service queries the directory service for user information. Although these users and group relationships are cached by Websense software, directory service machines must have the resources to respond rapidly if Websense software requests user information. See System requirements for this version for supported directory services.
For information on configuring Websense software to communicate with a supported directory service, see the Web Security Help. Websense software does not need to run on the same operating system as the directory service.
*
Network efficiency
The ability to connect to resources such as the DNS server and directory services is critical to Websense software. Minimize network latency for efficient Filtering Service performance. Excessive delays under high load circumstances can impact Filtering Service and may cause lapses in policy enforcement.
*
Microsoft SQL Server
A supported version of Microsoft SQL Server is required to host the Log Database, which stores reporting data for Websense Web Security solutions. See System requirements for this version for supported SQL Server versions.
*
SQL Server Standard or Enterprise works best for larger networks, or networks with a high volume of Internet activity, because of its capacity for storing large amounts of data over longer periods of time (several weeks or months).
*
SQL Server Express, a free, limited-performance database engine bundled into the TRITON Unified Installer, is best-suited to evaluation or proof of concept deployments. It can also be used by organizations with a low volume of Internet activity, or organizations planning to generate reports on only short periods of time (for example, daily or weekly archived reports, rather than historical reports over longer time periods).
