Wie können iOS-Devices ins Unternehmensumfeld eingebunden werden? Welches sind die gängigen Angriffe und wie kann man sich […]
This article was published when I just flipped through the final slides talking at “Hack in Paris” on smart meter wireless protocol issues. The combo of trainings, conference and the “nuit du hack” is held at the Disney Land Resort Paris for the 4th edition. Yes, Disney Land. When I arrived at the hotel I […]
Area41 (@a41con) is a security conference held in Switzerland. Its the successor of the highly successful Hashdays. Several Compass Security Switzerland employees volunteered to help organizing this event. Some say, we completely infiltrated Area41! The compound of Komplex 457 was pretty awesome. There was enough space in the main hall for to accommodate all viewers, […]
On this Wednesday (09.04.2014) I gave a presentation at OWASP Switzerland chapter. Initially I choose to present an overview of SSL/TLS, which is based on our previous blog article Compass SSL/TLS recommandations. Accidently, the timing with the OpenSSL heartbleed bug was perfect, so the presentation was updated in time with several slides about this current vulnerability. […]
Compass crew members just got back to work from a fun weekend/night at Insomni’hack (Geneva) where hackers met [0] to solve puzzles and enjoying the hacker community. On the way back home was sufficient time to clean-up systems and to reflect on some of the challenges. There was a variety of brain teasing puzzles relating […]
Microsoft has published a list of key security features [1] and also their security framework [2] for the Lync Server 2013. Those documents show how deeply MS integrated their SDL in the Lync products. It also indicates that Lync provides a solid security base out of the box: Encryption enforced for all communication between Lync […]
We have shortly described the Lync federations in a previous post. With the usage of federations the question comes about the privacy and the security of the user’s information (e.g. presence information). There are scenarios where an employee doesn’t answer the phone but is mentioned as “available” in Lync. This could lead to a misunderstanding […]
Microsoft Lync Server (a combination of “link” and “sync”, see [6]) communications software offers instant messaging (IM), presence, conferencing, and telephony solutions. Lync can be integrated with SharePoint or Exchange to extend its functionalities. Users can e.g. search for specific skills within the Lync client when SharePoint integration is enabled. Exchange is used as a […]

Mozilla created an extensive page [7] concerning the best current choice of SSL/TLS cipher suites, primarily for web servers. Compass Security agrees broadly with the article, but recommends some additional restrictions in order to provide the most resistance against active and passive attacks versus TLS secured connections: Use 3DES cipher instead of RC4 Disable SSLv3 support […]
