Monitoring Employee Web Usage with Accurate Logfile Analysis
Most IT administrators have read the headline-grabbing stories of employee Web abuse: an employee casually surfing the Web accidentally downloads spyware, compromising security and crippling a corporate network. Another employee repeatedly downloads pornographic material at work -- something HR only finds out about after a costly sexual harrassment lawsuit is filed and logfiles are subpoenaed.
Behind the headlines, however, are the thousands of hours lost by IT departments in resolving network slowdowns ? or analyzing volumes of raw logfile data for business managers looking to support disciplinary action. Losses like these can be prevented easily with employee Internet monitoring software.
Cyfin solutions for BorderManager
Wavecrest Computing's Cyfin Reporter Internet monitoring software tracks Web usage automatically, working with a proxy, firewall or caching appliance to read Web logs and analyze employee Web activity. Adding Cyfin Reporter logfile analyzer to Novell BorderManager allows you to quickly identify Web abuse, spot spyware and reduce legal liability risks by generating accurate, catagorized reports on up to 72 types of Web content. (Even better, an operator-only interface allows HR and other business managers to easily run reports on their employees' Web activity with no IT involvement.)
Accuracy in Internet montoring is critical. It is worth noting that Cyfin distinguishes unsolicited hits (banner ads) from user-initiated clicks, an important distinction many other logfile analyzers do not make. In addition, it can be easily set up to analyze Web activity against your organization's acceptable use policy settings, classifying activity as "acceptable," "unacceptable" or "neutral," according to your specifications and measuring usage against your threshold levels.
Cyfin's XML option generates clear, categorized reports on heavy volumes of logfile data in seconds. Support for AD and LDAP directory servers and automated product administration features makes setup easy. A complete data sheet is available at:
Setup and Configuration
Cyfin integrates easily with BorderManager proxy. Because the product simply analyzes BorderManager's logs, rather than operating inline between the firewall and the users, there virtually no impact on network speed or performance. Figure 1 illustrates the configuration:

3) If you selected common or extended logging, click the format name and specify the following parameters for each format:

- Log Rollover - How often the file is overwritten (rolls over) by time (days or hours) or by size (KB or MB).
