ip firewall screen dos-defense limit-session-source

When the host IP sessions table is overfilled, the host is unable to establish new sessions and it drops the requests (this may happen during various DoS attacks: SYN flood, UDP flood, ICMP flood, etc.). The command enables limiting the number of packets transmitted per second per source address, which attenuates DoS attacks.

ip firewall screen dos-defense syn-flood

This command enables the protection against SYN flood attacks. When the protection is enabled, the amount of TCP packets with the SYN flag set per second for one destination address is limited. The attack leads to the host reboot and its failure due to the necessity to process each TCP SYN packet and the attempts to establish a TCP session.

ip firewall screen dos-defense udp-threshold

This command enables the protection against UDP flood attacks. When the protection is enabled, the amount of UDP packets per second for one destination address is limited. The attack lead to the host reboot and its failure due to the massive UDP traffic.

ip firewall screen dos-defense winnuke

This command enables the protection against winnuke attacks. When the protection is enabled, TCP packets with the URG flag set and 139 destination port are blocked. The attack leads to the older Windows versions (up to 95 version) failure.

ip firewall screen spy-blocking fin-no-ack

This command enables the protection against IP-sweep attacks. When the protection is enabled, if more than 10 ICMP queries from one source arrive within the specified interval, the first 10 queries are dropped by the router and 11th with the following ones are discarded for the remaining interval time. The protection prevents an attacker from learning about network topology and hosts availability.

ip firewall screen spy-blocking port-scan

This command enables the protection against port scan attacks. If more than 10 TCP packets with the SYN flag arrive to several TCP ports and or more than 10 UDP packets arrive ti several UDP ports of one source within the first specified interval (<threshold>), then this behavior is recorded as port scan attack and all the following packets of that type are blocked for the second specified time interval (<TIME>). An attacker will not be able to scan the device open ports quickly.

ip firewall screen spy-blocking spoofing

The given command enables the protection against ip spoofing attacks. When the protection is enabled, the router checks packets for matching the source address and routing table entries, and in case of mismatch the packet is dropped. For example, if a packet with source address 10.0.0.1/24 arrives to the Gi1/0/1 interface and the given subnet is located after the Gi1/0/2 interface in the routing table, it is considered that the source address has been replaced. Protects from network intrusions with replaced source IP addresses.
