automatically enabled by default even though you may not need them. You can selectively
disable unneeded features to reduce vulnerability. Another common problem is Denial of
Service (DoS) attacks. A DoS sends floods of packets to an unsuspecting remote system in an
attempt to disrupt or stop normal operation. These unsuspecting remote systems are typically
discovered using ICMP or Ping. It is standard industry practice to block all ICMP and Ping
requests from off-net foreign hosts. This is typically done in a centralized location using
router/firewall technology which is more successful and cost effective than resolving the
issue at each host.
Logging
Logging of certain events can be stored both locally (within the VBrick device) or externally
(for example on a server). Local logs are stored in volatile memory. For preservation of
information, it is recommended that remote logging be utilized. Remote servers generally
offer ample storage and offer the additional benefit of collecting log information from
several VBricks simultaneously. When logging externally, specify either the IP address or
hostname of the actual server using the
Remote Event Log Destination
field. If remote
logging is enabled, the log information is sent via SNMP traps. When you enable logging, be
sure to set the system date and time (see System Time on page 11) or select a network time
server in order to get accurate time stamps in the logs.
Log Time Zone Determines the time zone where the unit is located. The time which
is included in the logged event displays time in this format.
Trap Log Local Stores logs locally within the unit. The log file will wrap after 20
events.
Trap Log Remote Sends log file to an external server.
