At the (heart) bleeding edge


The news about a possibly very nasty bug in the popular OpenSSL library got my attention almost weeks ago which hit out of the blue like a bombshell. Dubbed Heartbleed, this bug can potentially leak private keys installed at servers which make use of the affected libraries I learned, and shortly after that the first […]

Beat the Drum: Open Web needs to be Secure!


Mozilla is beating the drum for an Open Web at their new project page “Drumbeat“. Mitchell Baker, the Chair of the Mozilla Foundation has been regularly blogging about a more Open Web and what it might mean for us.

Sign your Code


Just recently the new Firefox version 3.5 was released with many new features, whistle and bells….native video and audio support being one of them. Porn private browsing mode and super fast rendering just another. If you haven’t updated and tried the latest and greatest from the house of Mozilla, I highly recommend to do that […]

Positive Indicators


Phishing attacks seldom use SSL certificates for their fake sites resembling Paypal, eBay or whatever, because they look as good without it. So far this apparently just worked fine because a somewhat careless user simply doesn’t pay attention to the microscopic indicators the browsers used to give us in the past. Well, that’s perhaps an […]

From the outside it’s just another Thunderbird as we know it - with some user interface changes and tweaks. But under the hood, the groundwork was laid for many future improvements and additions. The bird will have the Lightning calendar offered as a default installation option in its final version - and with it introduce […]

Securing Websites Economically


With a world-wide recession looming around the corner, budget conscious web site operators will look for ways to save resources wherever they can. Securing and serving multiple web sites from the same server always required a digital certificate and dedicated IP address [1]  for every site and domain. Needless to say this can add to […]

MITM attacks - do they really happen?


(If you happen to know what an MITM attack is, fast forward to here)
The man-in-the-middle (MITM) attack is the attempt by an attacker to implant himself between the client (browser, mail client, IM client) and a server serving some web page or other content. The attacker receives all requests and responses to and from the […]

SSL with Firefox 3


The new Firefox 3 browser is approaching fast its final release to the public and millions of fans will download the new product from Mozilla this month. For me this is a very exciting event and a great opportunity to show you which changes and improvements will effect us, specially in relation to SSL secured […]

Announcing Better Trust™


Long before browser vendors decided that the infamous padlock isn’t sufficient anymore for indicating a secure connection, I felt that I’d like to know much more about the certificates websites are using. Until today I either knew if the certificate was issued from one of the root certificates the browser vendor deemed trustworthy enough to […]
