MAC addresses can access the network (Port
Security)

• 256 static VLAN, up to 4 K dynamic VLAN
• Dynamic ARP
Auto DoS Attack Prevention
Denial of Service (DoS) attacks try to disable a
device or network so users no longer have access
to network resources. Auto DoS Attack Prevention
module matches attack types in switches and
prevent network outage
Types of DoS Attacks can be prevented
• Land Attacks — These attacks result from
sending a specially crafted packet to a machine
where the source host IP address is the same as
the destination host IP address. The system
attempts to reply to itself, resulting in system
lockup.
• Blat Attack — These switch result from sending
a specially crafted packet to a machine where the
source host port is the same as the destination
host port. The system attempts to reply to itself,
resulting in system lockup.
• SYNFIN Scans — SYNchronization (SYN,
ACKnowledgement (ACK) and FINish (FIN)
packets are used to initiate, acknowledge and
conclude TCP/IP communication sessions. The
following scans exploit weakness in the TCP/IP
specification and try to illicit a response from a
host to identify ports for an attack:
- Scan SYNFIN — SYN and FIN bits are set in the
packet.
- Xmascan — TCP sequence number is zero and
the FIN, URG and PSH bits are set.
- NULL scan — TCP sequence number is zero and all
control bits are zeros.
- SYN with port <1024 — SYN packets with source
port less than 1024.
• Smurf Attacks — This attack uses Internet Control
Message Protocol (ICMP) echo requests packets
(pings) to cause network congestion or outrages.
• Ping Flooding — This attack floods the target
network with ICMP packets.
• SYN/SYN-ACK Flooding — This attack floods the
target network with SYN or SYN/ACK packets.
Network Administration Security
• Password required for administrators
Network Management

• SNMP v1, v2
• IP management: static IP
• RMON
• Port mirroring: supports Source/Destination/Both
port mirroring
• Cable Diagnostic
MIB Information
