DOS attacks

A denial of service (DOS) attack is an attack that clogs up so much memory on the target system that it cannot serve its users, or it causes the target system to crash, reboot, or otherwise deny services to legitimate users. These days, DOS attacks are very common; indeed, just about every server is bound to experience such an attack at some time or another.
There are several different kinds of DOS attacks, the most popular of which are follows:

• Ping of Death
• Teardrop attacks
• SYN-flood attacks 
• Land attacks
• Smurf  attacks
• UPD-flood attacks
• Distributed DOS attacks
• Modem-disconnect attacks
