Why Are Distributed Denial Of Service Attacks So Hard To Defend Against?

by

DDoS AttacksDDoS attacks have been hitting the headlines with increasing frequency over the last few months. They’re a favored strategy of “hacktivists”, extortionists, and online criminals hoping to create a distraction. In principle, DDoS attacks are quite simple. At the most basic level, a collective of compromised Internet-connected machines direct a flood of data at the target with the aim of degrading its performance, either by saturating its connection to the Internet or using up its resources. The result is a site or service that is no longer usable by visitors.

If you’re a Feedly user, you’ll have experienced the results of a DDoS attack recently. Attackers flooded the RSS feed reader’s servers with data, in effect knocking it out of service for several days with the intention of extracting a payment from the company — a sort of modern protection racket.

by

Avoid Site Security IssuesSite security is a complex issue. The online economy is huge and hackers stand to reap considerable benefits from attacks against sites that store sensitive data or give them access to large numbers of visitors. Hackers are a motivated and intelligent group of people, albeit a group with a consistent lack of concern for their fellow Internet users.

In spite of the potential complexity of securing a site, attacks tend to fall into a number of clearly defined categories, and the mitigation of a significant majority of attacks can be achieved by following a small set of best practices. That’s not to say that by implementing the strategies we’re going to discuss here a site will be rendered impervious – that’s all but impossible, but most hackers focus on low hanging fruit, and by ensuring that a site is difficult to exploit, web masters will discourage all but the most persistent online criminals.

Five Languages Every Web Developer Should Know

by

Web Developer LanguagesOccasionally, I wonder what might happen if the Internet just stopped working one day. It’s not a terribly pleasant thought, is it? These days, we’re so reliant on our connectivity that if some outside force were to strip it away from us, it’d likely lead to a complete societal collapse.

There are upsides to this reliance, of course – particularly if you’re in the field of web development. If you’re capable of stomaching the learning cliff and the long hours you’ll likely end up working, there’s never been a better time to be a web developer. So long as you’ve got the right knowledge and skills under your belt, you’ll never be wanting for new clients.

After all, as long as the Internet exists, someone’s going to want a website built.

Even more striking is the fact that if companies and others running DNS servers put their mind to it, DNS amplification attacks could be rendered impossible.
