Denial of Service Commands
Denial of Service Commands
This section describes the commands you use to configure Denial of Service
(DoS) Control. FASTPATH software provides support for classifying and
blocking specific types of Denial of Service attacks. You can configure your
system to monitor and block these types of attacks:
◆
SIP = DIP:
Source IP address = Destination IP address.
◆
First Fragment:
TCP Header size smaller then configured value.
◆
TCP Fragment:
Allows the device to drop packets that have a TCP payload
where the IP payload length minus the IP header size is less than the
minimum allowed TCP header size.
◆
TCP Flag:
TCP Flag SYN set and Source Port < 1024 or TCP Control Flags
= 0 and TCP Sequence Number = 0 or TCP Flags FIN, URG, and PSH set
and TCP Sequence Number = 0 or TCP Flags SYN and FIN set.
◆
L4 Port:
Source TCP/UDP Port = Destination TCP/UDP Port.
◆
ICMP:
Limiting the size of ICMP Ping packets.
◆
SMAC = DMAC:
Source MAC address = Destination MAC address
◆
TCP Port:
Source TCP Port = Destination TCP Port
◆
UDP Port
: Source UDP Port = Destination UDP Port
◆
TCP Flag & Sequence:
TCP Flag SYN set and Source Port < 1024 or TCP
Control Flags = 0 and TCP Sequence Number = 0 or TCP Flags FIN, URG,
and PSH set and TCP Sequence Number = 0 or TCP Flags SYN and FIN set.
◆
TCP Offset:
Allows the device to drop packets that have a TCP header
Offset set to 1.
◆
TCP SYN:
TCP Flag SYN set.
◆
TCP SYN & FIN:
TCP Flags SYN and FIN set.
◆
TCP FIN & URG & PSH:
TCP Flags FIN and URG and PSH set and TCP
Sequence Number = 0.
◆
ICMP V6
: Limiting the size of ICMPv6 Ping packets.
◆
ICMP Fragment
: Checks for fragmented ICMP packets.
