In the previous article, we introduced, arguably, the most important metric to measure WAF quality (in subsequent entries we will talk about WAF performance). But we left one question flying in the air: How can we achieve that our WAF rules provide a virtually null False Positive rate, keeping at the same time a very low percentage of False Negatives?
It's hard to miss all the media attention surrounding data breaches in healthcare. If you're involved in information security at a healthcare organization, it's no surprise to you that more than 143 million individuals have been affected by data breaches since HHS started tracking incidents in September 2009.
I said in my last article that one of the key factors when it comes to judging the effectiveness of a WAF is accuracy. There is a metric that, measured in an objective way, provides an unmistakable view of quality and accuracy of a WAF solution: false negatives and false positives.
The Q3 2015 State of the Internet Security Report is now available for download at www.stateoftheinternet.com/security-report. Among the highlights: a continued upward trend in DDoS attacks, and attacks fueled by the easy availability of DDoS-for-hire sites that identify and abuse exposed Internet services, such as SSDP, NTP, DNS, CHARGEN, and even Quote of the Day.
Tangina Barros, the medium in the Poltergeist film series, taxes and Internet security. These three things have in common that they scare, they intimidate and they may keep you awake at night. With regards to the first two topics, the only thing I can do is remember that Poltergeist is just a movie, seriously, just a movie (I keep saying that to convince myself, quite unsuccessfully, though) and that
While hospitals are ramping up security efforts to protect information, a large percentage of them are vulnerable to attacks on their web sites. Less than two-thirds of hospitals participating in a recent survey reported having on-premise web application firewalls in place, and fewer than half reported having defenses in place to thwart distributed denial of service (DDoS) attacks.

Open redirection is the last item on the OWASP Top 10, and it is considered a Web application functionality that can be used by attackers to redirect users from trusted domains to untrusted domains. But it is a potent problem, as Akamai's Threat Research Team discovered in their research on an unusual malicious SEO attack campaign that abused Web applications' open redirect functionality.
I've received numerous questions about how I found so many Wordpress plugin vulnerabilities and how to write the exploits that were essential to the research. I'll be honest, it's not hard if you have some experience in php programming and basic knowledge of secure programming. To simplify things, we will narrow down certain traits of what plugins to examine.
Today is Cyber Monday, which is historically the day when many retailers encourage online holiday shopping. Online retailers may see large spikes in traffic to their sites. It is possible that some may interpret these spikes as a DDoS, but in reality it may be what we refer to as a "flash mob". A flash mob is a large amount of legitimate traffic being sent to a specific site. One
