OPTA revokes Diginotar License as TTP

Wout de Natris: "In this decision OPTA revokes the registration of Diginotar as a so called Trusted Third Party. Diginotar issued certified certificates for digital signatures.

This included Dutch government websites, but also led to severe breaches of privacy for Iranian end users, in multiple countries. As a result of OPTA's decision all certificates issued by Diginotar have to be revoked, while at the same she is forbidden to issue new ones. more

Reducing the Risks of BYOD with DNS-Based Security Intelligence; Part 2: Taking Control

In part 1, I talked about some of the risks associated with BYOD. But there are actions you can take to greatly reduce this risk. One effective method for limiting the risk of BYOD is to employ DNS-based security intelligence techniques. DNS-based security intelligence makes use of an enterprise's caching DNS server to monitor and block DNS queries to known botnet command and control (C&C) domains. more

Leveraging DNS for Subscriber Loyalty

There has been a lot of talk about how the DNS can provide network-based security, and how DNS is in the best position to detect malware traffic before it does any harm. But what does this mean for end users? How does it make their online lives easier and more secure? DNS servers that are aware of sites that host malware, perform phishing activities (harvesting bank details, for instance) and other nefarious misbehaviors, can prevent end users from ever going to those sites. more

Study Reveals 76% of Internet Users Vulnerable to Browser History Detection

A recent study reveals a browser history detection method, largely dismissed as an issue with minimal impact, can in fact be used against a vast majority of Internet users with significant malicious potential. Researchers, Artur Janc and Lukasz Olejnik, analyzed real-world results obtained from 271,576 Internet users and have reported the results in a paper titled, "Feasibility and Real-World Implications of Web Browser History Detection". more
