DDos Protection

A distributed denial-of-service (DDoS) attack is one in which a multitude of compromised systems attack a single target, thereby causing denial of service for users of the targeted system. The flood of incoming messages to the target system essentially forces it to shut down, thereby denying service to the system to legitimate users.

In a typical DDoS attack, the assailant begins by exploiting a vulnerability in one computer system and making it the DDoS master. The attack master, also known as the botmaster, identifies and identifies and infects other vulnerable systems with malware. Eventually, the assailant instructs the controlled machines to launch an attack against a specified target.

There are two types of DDoS attacks: a network-centric attack which overloads a service by using up bandwidth and an application-layer attack which overloads a service or database with application calls. The inundation of packets to the target causes a denial of service. While the media tends to focus on the target of a DDoS attack as the victim, in reality there are many victims in a DDoS attack -- the final target and as well the systems controlled by the intruder. Although the owners of co-opted computers are typically unaware that their computers have been compromised, they are nevertheless likely to suffer a degradation of service and not work well.

Distributed Denial of Service (DDoS) attacks continue to remain the top threat to IT security and have evolved in almost every way to do what they do best: shut down your vital online services. There is almost an unlimited array of tools that Hacktivists and Cyber terrorists can use to prevent access to your network. Sophisticated DDoS attacks target Layer 7 application services where they are much smaller in size making it nearly impossible for traditional ISP-based mitigation to detect them.

BTS is offering the FortiDDoS purpose-built appliances provide real-time visibility into the networks in addition to detection and prevention of Distributed Denial of Service (DDoS) attacks. FortiDDoS helps you protect your internet-facing infrastructure from threats and service disruptions by surgically removing network and application-layer DDoS attacks. You can defend your critical on-premise and cloud infrastructure from attacks while relying on sophisticated filtering technologies to allow legitimate traffic to continue to flow. These scalable, high-performance appliances deliver proven DDoS defense, and are completely interoperable with your existing security technologies and network infrastructure.
