3. Introduction DOS is an attack used to deny legitimate users access to a resource such as accessing a website, network, emails, etc. or making it extremely slow.  DoS is the acronym for  D enial  o f  S ervice. This type of attack is usually implemented by hitting the target resource such as a web server with too many requests at the same time . This results in the server failing to respond to all the requests. The effect of this can either be crashing the servers or slowing them down.

4. TYPES OF DOS ATTACK DoS – this type of attack is performed by a single host Distributed DoS – this type of attack is performed by a number of compromised machines that all target the same victim. It floods the network with data packets

5. DoS Protection: Prevent an attack An organization can adopt the following policy to protect itself against Denial of Service attacks. Attacks such as SYN flooding take advantage of bugs in the operating system.  Installing security patches can  help reduce the chances of such attacks. Intrusion detection systems  can also be used to identify and even stop illegal activities Firewalls  can be used to stop simple DoS attacks by blocking all traffic coming from an attacker by identifying his IP. Routers  can be configured via the Access Control List to limit access to the network and drop suspected illegal traffic.
