The network layer is responsible for routing and forwarding data packets between different networks. DDoS attacks at this layer aim to deplete network bandwidth resources. Common attack subcategories include ICMP flood attack, ARP flood attack, and IP fragmentation attack. Attack Subcategory Attack Mecha...
Smurf attack:A distributed denial-of-service attack where a large numbers of Internet Control Message Protocol (ICMP) packets with the intended victim's spoofed source IP are broadcast to a computer network using an IP broadcast address. Buffer overflows:Attackers exploit buffer overflow issues by ...
Victim’s server becomes overloaded:With enough ICMP reply packets forwarded, the victim’s server is overloaded and potentially rendered inoperable. Types of Smurf Attacks Smurf attacks are generally categorized as basic or advanced. The only difference in the type of attack is the degree of the ...
ICMP flood attack.Sometimes called aping flood attack, the goal of this attack is to overwhelm the target device with echo request packets. Each echo request packet must be processed by the target and responded to with Echo Reply messages. This sucks up all the target computer's resources, c...
Smurf: This is a DDoS attack usingInternet Control Message Protocol (ICMP)packets to overwhelm a system. Secure Sockets Layer (SSL) Evasion: This exploits SSL and Transport Layer Security (TLS) encryption that hides malicious content to avoid detection and get past network security. ...
Bandwidth-consuming DoS attack An attacker sends a large number of forged ICMP Echo Request packets. The CPUs of network devices, such as switches and routers, need to respond to these packets, occupying a large amount of bandwidth and CPU resources. This DoS attack, like other DoS attacks, ...
Smurf Attack– in this attack, ICMP packets that have fake or spoofed IP addresses (of the intended victim) are sent to another device or server with a broadcast IP address; when the broadcasted ICMP echo replies are sent from the devices on the other side of the broadcast, they will bomb...
In aSmurf attack, the attacker transmits an ICMP packet that has a spoofed or fakedIP address. When the equipment on the network replies, each reply gets sent to the spoofed IP address, and the target is flooded with a ton of ICMP packets. This kind of attack is also typically only a...
the device cannot process other services due to insufficient memory resources. To mitigate such an attack, the device starts a reassembling timer. If reassembly cannot be finished before the timer expires, the device returns an ICMP Error packet to the sender; if reassembly cannot be finished afte...
