monitor the access of workstations in the LAN to the IP routing function of the
device.
Further important features of the Firewall are
Intrusion Detection
Break-in attempts into the local network or on the central Firewall are rec-
ognized, repelled and logged by the Intrusion Detection system (IDS) of
the LANCOM DSL. Thereby it can be selected between logging within the
device, email notification, SNMP trap or SYSLOG alarms.
Denial-of-Service Protection
Attacks from the Internet can be break-in attempts as well as attacks with
the aim of blocking the accessibility and functionality of individual
services. Therefore a LANCOM DSL is equipped with appropriate protec-
tive mechanisms, which recognize well-known hacker attacks and which
guarantee the functionality.
Quality-of-Service / Traffic management
The generic term Quality-of-Service (brief: QoS) summarizes the functions
of the LANCOM which guarantee certain service qualities. The advantage
is that the QoS functions can take place by means of the existing powerful
classification methods of the Firewall (e.g. limitation of subnetworks,
single workstations or certain services).
Guaranteed minimum bandwidths give priority to enterprise critical appli-
cations, VoIP PBX installations or certain user groups.
More details about the function of the Stateful Inspection Firewall of
your LANCOM Router can be found in the reference manual on the
LANCOM CD.
