Distributed Denial of Service Attacks are when a series of devices initiate flows of traffic to or from a location that causes and impediment of the network, server or Internet connectivity for a location. DDOS attacks most often are occuring at the time a) the attacker is also stealing data from the affected site. The purpose of DDOS is mask the theft of data and the destination location that that data is being taken to. By causing a DDOS at the time of the theft of data, the thief is able to overwhelm the security logging capabilities of firewalls and other security devices, thus the pathway of the theft can likely not be ascertained. The ultimate root of all Distributed Denial of Service Attacks is lack of proper security of systems at the site that is being attacked. This can be compounded by underpowered firewalls, gateways and other security devices, however at the root, these devices are not likely at fault for the issues related to DDOS. Simply put, these systems can easily get overwhelmed at the even poorly creafted DDOS attacks. s are initiated from the network source as single points of bottlenecks the lack of performance capacity on these devices only exibit DOS is more apparent sooner, but do not fundamentally fix the problem of internal network security. If the gateways have performance issue, it is usually an early warning sign that internal security is not properly handled. Thus the only way to fix the problem and to make sure that it does not recur is to ensure that all systems on the internal network are fully secured. The vast majority of internal network security flaws are due to lack of software patches and upgrades on the operating systems devices connected to the network including:

1) Conventional Computers and servers Operating Systems 2) Routers, Switches, Firewalls, Wifi Access Points 3) External guest computers and devices. 4)
