SCEP Validation Service Integration with 3rd-party MDM Applications

Posted by CSS Technical Team on Aug 16, 2012 12:27:00 PM

CSS recently discovered and published information on a potential privilege escalation attack in SCEP-based Certificate Issuance Systems. After this discovery, CSS created the SCEP Validation Service, which aims to close this attack by validating the certificate contents before the Certificate Authority sends it to the requestor. CSS’ patent-pending solution ships today with our Mobile Certificate Management System (mCMS) v 1.1 software. CSS’ SCEP Validation Service is architected as a set of components that can also be integrated into 3rd-party Mobile Device Management (MDM) products.

Security Vulnerability- The Use of the Simple Certificate Enrollment Protocol (SCEP) and Untrusted Devices

Posted by Ted Shorter on Jun 27, 2012 11:19:38 AM

It’s been in the works for quite some time, but we are finally able to publicly announce a problem that we’ve encountered, related to the use of the Simple Certificate Enrollment Protocol, or SCEP, in conjunction with mobile devices. We’ve been working for months behind the scenes with the folks at the United States Computer Emergency Readiness Team (US-CERT) and CERT/CC at Carnegie Mellon our customers, and a number of vendors as well, to help raise awareness of the issue. The CERT report can be found here, and we have a whitepaper and video overview on our website to provide more information.

It should be noted that not all MDM usage of SCEP is equally vulnerable. The scenarios that cause the most concern to us are those that involve the use of SCEP to issue authentication certificates to enterprise systems such as ActiveSync, WiFi, and VPN. In some cases it may be possible to use alternative configurations that reduce or eliminate these risks; in others, it may be more difficult. CSS is willing to help customers assess their specific usage of SCEP and PKI to determine their degree of exposure.

Certified Security Solutions sent a team to the 2012 RSA Security Conference in San Francisco where one of the underlying themes was mobile security. Located in the Microsoft Pavilion, team CSS boasted a 'Got PKI?' theme centered around PKI best practices and the power of digital certificates on mobile devices. Booth conversations included PKI as a service in addition to leveraging CSS' own software solution, the Certificate Management System (CMS) for digital certificate management and enrollment in a Microsoft PKI. Visitors to the booth were genuinely excited to see a mobile security solution from a company that "gets" PKI. CSS' CTO, Ted Shorter, and Director of Business Development, Uri Lichtenfeld, presented a theater session titled 'Do's and Don’ts of PKI and Certificate Management for Mobile Devices.'

iOS 5, S/MIME, and Digital Certificate Management

Posted by Ted Shorter on Sep 15, 2011 9:50:12 AM

iOS 5, Apple’s new operating system for iPad, iPhone, and iPod Touch, will be released “soon” – Apple officially says “this Fall,” and many prognosticators are pointing to sometime in October. While the new release has hundreds of new features, the feature that’s of particular interest to digital identity practitioners such as CSS is one that’s received very little press to date:


The current version of iOS4.x supports the use of digital certificates for authentication: to things like wireless networks, VPNs, and Microsoft ActiveSync . But starting with iOS 5, iPhone, iPad, and iPod Touch users will be able to send and receive digitally signed and encrypted email messages directly from their device.
