UDP Bomb attack is an offensive type of Denial of Service (DoS) against a server or computers connected in a network. To perform a UDP Bomb attack against a server, an attacker sends an UDP (User Datagram Protocol) which has been engineered so dispoof or contain values ??that are invalid in certain fields.
If the server is not protected still uses the operating system (operating system) that can not handle long invalid UPD packages, then the server will crash immediately. Examples of operating systems that can be dropped by UDP bomb attack is a SunOS version 4.1.3a1 or earlier versions. Most operating systems will discard UDP packets that are not valid, so the operating system will not crash. However, to make it more secure, you should use a packet filtering through the firewall to monitor and block attacks such as UDP Bomb attack.
IP spoofing is also known as the Source Address Spoofing, namely forgery attacker’s IP address so that attacker considers the target IP address is the IP address of the host in the network rather than from outside network. Suppose the attacker has a type A 66.25.xx.xx IP address when the attackers do This type of attack the network that attacked the attacker will assume the IP is part of the Networknya 192.xx.xx.xx eg, IP type C. IP spoofing occurs when an attacker ‘outsmart’ packet routing to change the direction of data or transmission to different destinations. packet to routing is usually transmitted in a transparent and clear so as to make the attacker to easily to modify the data origin or destination of data. This technique is not only used by the attacker but also used by security professionals to download tracing the identity of the attacker.
Protocol that handles communication between computers most successful in the spoof. ICMP (Internet Control Message Protocol) is one of them (vulnerable) because the protocol is bypassed by the information and error messages between two nodes in the network. Internet Group Message Protocol (IGMP) can be exploited by using this type of attack because IGMP report error conditions user-level datagram, but it also contains routing information protocol and Information Network. (UDP) User Datagram Protocol can also be ‘requested’ to display the identity of the target host.
The solution to prevent IP spoofing is a way of securing the packet-packet is transmitted and installing screening policies. Encryption Point-to-point can also prevent users who do not have the right to read the data / packet. Authentication can also be used to filter the source a legal and not a source that has been in the spoof by attackers.
In another prevention, Administrator can use the signature for packages that communicate in the network so convincing that the package is not modified in transit. Anti Spoofing rules (anti-spoof rules) which basically tells the server to reject packet is coming from outside the visible coming from the inside, generally this will break any spoofing attacks.
