Apache, the open-source Web server, is the most popular Web server on the planet. It’s also as safe as safe can be. Well, usually it is. An old, unfixed security hole has come back to haunt the Apache webmasters in the form of a Distributed Denial of Service (DDoS) attack tool: Apache Killer.
You may have already heard about this, and ignored it. I mean, in a world where every day brings a new security hole announcement but the Web keeps working anyway, many people have taken to a “Who cares” attitude. That’s usually a mistake. And, when it comes to Apache Killer, it could be a business-killing mistake.
