What is Denial of Service (DoS)?
Denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) are attacks to force the targeted computer/network(s) to reset, crash, or consume its resources so it can no longer provide service or halt communication entirely. Therefore, the attack obstructs either a machine or an entire network of resources and becomes unavailable to the intended users. There are two general forms of DoS attacks: those that crash services and those that flood services. The most common kind of DoS attacks are flood attacks, which simply means to send more traffic to a network address than the programmers anticipated. Other forms of DoS of attacks are SYN, Teardrop and Smurf attacks, Viruses and possibly physical human attacks.
What are the Risks involved?
Typical victims for DoS attacks are online businesses, carriers and service providers. Although a DoS attack does not usually result in the theft of information or other security loss, it can cost the target person or company a great deal of time and money resulting in revenue loss or increased network costs. DoS attacks can contribute to a loss of service, such as e-mail, temporary loss of all network connectivity and services. It can also destroy programming and files in affected computer systems. In some cases, DoS attacks have forced Websites accessed by millions of people to temporarily halt operation, thus causing bad business reputation and increased operational costs as a result.

How can we help?
The implementation of effective Denial of Service protection program will help protect a network against attacks, that inhibit or stop network availability. We can ensure protection by identifying behaviours of legitimate normal traffic, attack traffic and unusual patterns created by legitimate activity, while filtering out potential threats.
