A DoS or ‘Denial of Service’ Attack is a targeted attempt to bring a website or online resource down, usually by means of repeatedly loading various site data, ultimately overloading the server or associated hardware or networking. A DDoS is a ‘Distributed Denial of Service Attack’ – generally meaning the DoS is coming from multiple PC’s or Networks simultaneously.
“One common method of attack involves saturating the target machine with external communications requests, such that it cannot respond to legitimate traffic, or responds so slowly as to be rendered essentially unavailable. Such attacks usually lead to a server overload. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.”
While the exact method may vary, the end result is often the same.
While we can offer some temporary relief of DDoS related issues for a 24 hour period – longer attacks will require the intervention of a 3rd party to mitigate, as we do not have the specialized hardware infrastructure in place to mitigate these attacks in an ongoing manner.
There are a number of Cloud-Based ‘DDoS Mitigation’ services which one can subscribe to, which filter the incoming traffic, and mitigate large DDoS attacks. A simple web search for ‘DDoS Mitigation’ or ‘DDoS Protection’ should yield the appropriate results.
