Distributed Denial of Service (DDoS) Attack
How is a DDoS executed against a website?
A website DDoS is executed by flooding one or more of the site’s web servers with so many requests that it becomes unavailable for normal use. If an innocent user makes normal page requests during a DDoS attack, the requests may fail completely, or the pages may download so slowly as to make the website unusable. DDoS attacks typically take advantage of several computers which simultaneously launch hundreds of thousands of requests at the target website. In order not to be traced, the perpetrators will break into unsecured computers on the internet, hide rogue DDoS programs on them, and then use them as unwitting accomplices to anonymously launch the attack.
Is there a quick and easy way to secure against a DDoS attack?
No. From a simplistic perspective, the best solution is to secure computers from being hijacked and used as attack platforms. This cuts the problem off before it can ever manifest. Thus many experts suggest that we “pull together as a community” to secure our internet computers from becoming unwitting accomplices to such malicious intruders. Unfortunately, for every business that has the knowledge, budget, and inclination to make such changes, there are many more which lack such resources.
Plus, the attackers are most likely going to use non-commercial computers as attack platforms, because they are usually easier to break into. University systems are a favorite, because they are often understaffed or the systems are set to minimum security levels to allow students to explore the systems as part of their education. Further, this is not just a national problem. Any internet server in the world could be used as an attack platform.
Still, the simplest and most effective solution for preventing DDoS is through a global cooperative effort to secure the internet. The first step in the process, therefore, is concerned with scanning your internet computers to make sure they are not being used as unwitting DDoS attack platforms. This is not just good internet citizenry, however, because this also serves to document and verify that your internet computers are not suspect when DDoS attacks occur.
