Apr 10 2014 - FortiGates and Heartbleed Bug
An information disclosure vulnerability has been discovered in OpenSSL versions 1.0.1 through 1.0.1f that affects FortiGate (FortiOS) 5.0 and higher, FortiAuthenticator 3.0 and higher, FortiMail 5.0 and higher, FortiVoice, and FortiRecorder.
The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).
The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users.
See: http://www.fortiguard.com/advisory/FG-IR-14-011/ on how to mitigate on Fortinet products and http://heartbleed.com for more information.
Nice humorous explanation of the bug here: http://www.giss-uk.com/images/heartbleed_explanation.png
Please contact us for assistance in remotely configuring/upgrading your Fortinet technology to prevent this vulnerability.!
Mar 11 2014 - Protecting Research
Today GISS installed a high-performance FortiNet FortiGate firewall cluster for an advanced scientific research centre based in Cambridgeshire. When asked for a brief testimony a few days later from this much-valued new GISS customer - the feedback was: "The GISS team recently replaced our Cisco ASA devices with a pair of FG-600Cs. The pre-installation discussions were thorough and helpful, and the planning for the transition anticipated potential problems and mitigated them. The actual installation went very smoothly indeed and our users were back online with the absolute minimum of downtime. Overall our experience of working with GISS has been very satisfactory indeed." - fine feedback, greatly appreciated!
