scan one item at a time, resulting in reduced scanning performance, and possibly,
dropped traffic.
When InterScan Gateway Security Appliance is in diskless mode, the hard disk LED
turns red and become static. InterScan Gateway Security Appliance notifies the
administrator, by email, if there is a problem with the system hard disk.
See Appendix D. Removing the Hard Disk
False Positives
A false positive occurs when a Web site, URL, "infected" file, or email message is
incorrectly determined by filtering software to be of an unwanted type. For example,
a legitimate email between colleagues may be detected as spam if a job-seeking filter
does not distinguish between
resume (to start again) and résumé (a summary of work
experience)
You can reduce the number of future false positives in the following ways:
1. Update to the latest pattern file (phishing, virus, spam, and so on).
2. Exempt the item from scanning by adding it to an Approved List.
3. Report the false positive to Trend Micro.
LAN Bypass
LAN bypass is a fault-tolerance solution that allows InterScan Gateway Security
Appliance to continue to pass traffic if a software, hardware, or electrical failure
occurs.
InterScan Gateway Security Appliance has three (3) user-configurable Copper-based
Ethernet ports. Each Ethernet port has two (2) indicator lights that allow you to
determine the port’s current state and duplex speed. View the port indicator lights to
determine if LAN bypass is currently active.
