At the start of last week, we received great news regarding new improvements to a very popular security app, “Google Authenticator”. A feature it was lacking for a long time was finally implemented, “cloud backups”. However, after a few days, the security community realized the new feature wasn’t as good as everybody was assuming.

In a previous blog post published earlier this year I explored some security considerations of the well known “clipboard” functionality that most operating systems provide. Long story short, in my opinion there is a lot more that could be done to protect the users (and their sensitive data) from many attacks that use of clipboard […]
Content-Security-Policy (CSP) is an important mechanism in today’s web security arsenal. Is a way of defending against Cross-Site Scripting and other attacks. It isn’t hard to get started with or to put in place in order to secure your website or web application (I did that exercise in a previous post). However when the systems […]

Last January I made a small post about setting up a “Content-Security-Policy” header for this blog. On that post I described the steps I took to reach a final result, that I thought was good enough given the “threats” this website faces. This process usually isn’t hard If you develop the website’s software and have […]
A couple of weeks ago, I gave a small talk on the Madeira Tech Meetup about a set of HTTP headers that could help website owners protect their assets and their users. The slides are available here, just in case you want to take a look. The content of the talk is basically a small […]
When going on a trip it is now common practice to consider staying on an rented apartment or house instead of an hotel or hostel, mostly thanks to AirBnB which made it really easy and convenient for both side of the deal. Most of the time the price is super competitive and I would say […]

These tools are quite well known in the python community and used together will provide you with great feedback about common issues and pitfalls. Safety and […]
