WebScan for Linux combines antivirus and content security features in order to protect the network on the gateway or proxy server level. WebScan was designed to allow organizations to control the type of Web traffic content that can flow through the gateway and to protect the network from viruses that gain access through proxy servers. WebScan can scan Web pages for content policy violations, viruses, worms, Trojans and other malware. It also allows blacklisting of MIME file types, such as audio and video, so that Internet bandwidth is used effectively. Also, HTTP file uploads can be blocked to prevent theft or leakage of sensitive data. Unauthorized access to certain Web sites also can be prevented based on ratings by organizations such as RASCi, Safe Surf and ICRA. For administration, WebScan offers an extensive reporting system for policy violations and a Web-based GUI front end for easy configuration and administration.

The PostgreSQL Global Development group has released version 8.0 of PostgreSQL, an object-relational database management system. Key new features for version 8.0 include savepoints, an SQL-standard feature that allows specific parts of a database transaction to be rolled back without aborting the entire operation. Also new for PostgreSQL 8.0 is point-in-time recovery, a feature that allows full data restoration from the automatic and continuously archived transaction logs, which is an alternative to hourly or daily backups. Version 8.0 also offers tablespaces, which allow the placement of large tables and indexes on their own individual disks or arrays, improving query performance. Finally, PostgreSQL offers improved disk and memory usage through the use of the Adaptive Replacement Cache algorithm, the new background writer and the new vacuum delay feature.
