Retina Helps Identify Weak Certificates

Posted September 25, 2012    Jerome Diggs

Microsoft has released a Security Advisory for the upcoming patch to increase minimum bit levels of certificates to 1024 bit security advisory 2661254.  The expected release date for this patch is Oct 9th at which time the update will be available through Windows Update. This change to the minimum bits level of certificates will change the Windows certificate system and will cause it to stop accepting certificates that are less than 1024 bits as those keys are considered ‘weak’. This change will affect all Windows operating systems above Windows XP SP3 and Windows 8 already implements the tighter certificate check.

To help identify systems that are leveraging weak certificates the Retina solutions have audit ID 12609 – SSL Certificate Weak Public Key Strength enabled by default.

This audit is available with Retina Community and the commercial version of Retina.  Users can include these new checks in a general vulnerability scan, or can create a targeted scan to specifically look for these specific vulnerabilities.

Feel free to download and try out our community version to discover, assess and gain remediation guidance in our simple to use standalone scanner. In addition to standard assessment of patches, insecure configurations and zero-days, the commercial version of Retina Network also provides in-depth credentialed scans for over 2500 operating systems, databases, web applications, network devices, applications, mobile devices, cloud providers and virtual applications.  https://www.eeye.com/purchase/compare-products

Once you’ve identified systems that need to be updated you’ll need to consult with the various vendors on the processes required to incorporate stronger certificates for their products.  For detailed information on how this affects Beyondtrust’s products please visit our support page.

GHOST Vulnerability…Scary Indeed

Posted January 28, 2015    BeyondTrust Research Team

A vulnerability discovered by Qualys security researchers has surfaced within the GNU C Library that affects virtually all Linux operating systems. The vulnerability lies within the various gethostbyname*() functions and, as such, has been dubbed “GHOST.” GHOST is particularly nasty considering remote, arbitrary code execution can be achieved. In an effort to avoid taxing DNS lookups, glibc developers introduced…

Your New Years Resolution: Controlling Privileged Users

Posted January 27, 2015    Dave Shackleford

Is 2015 the year you get a better handle on security? The news last year was grim – so much so, in fact, that many in the information security community despaired a bit. Really, the end-of-the-year infosec cocktail parties were a bit glum. OK, let’s be honest, infosec cocktail parties are usually not that wild…
