Always On VPN Device Tunnel and Certificate Revocation

Always On VPN Device Tunnel and Certificate Revocation

Recently I wrote about denying access to Windows 10 Always On VPN users or computers. In that post I provided specific guidance for denying access to computers configured with the device tunnel. To summarize, the process involved exporting the device certificate from the issuing Certification Authority (CA) server and placing it in the Untrusted Certificates certificate store on each VPN server.…

Denying Access to Always On VPN Users or Computers

Denying Access to Always On VPN Users or Computers

Once Windows 10 Always On VPN has been deployed in production, it may be necessary at some point for administrators to deny access to individual users or computers. Commonly this occurs when an employee is terminated or leaves the company, or if a device is lost, stolen, or otherwise compromised. Typically, this means that user accounts and computer accounts in Active Directory are disabled, and…

A number of technical problems are arising with the widespread distribution of vehicular ad-hoc networks. Privacy and authentication mechanisms are of major concern. If security is not integrated with the system, it leads to anti-social and criminal behavior and endanger the benefits of the deployment of VANETs. A suitable authentication procedure is to implement the Public-Key Infrastructure (PKI) , where each node in the VANET has a set of authentic certificates. Traditional PKI systems makes use of Certificate Revocation Lists to check the validity of the certificate and thereby the signature. In this paper, a new method that replaces CRL with revocation checking process is proposed. When a node is found to be illegitimate or compromised, it is revoked by generating a revocation message and broadcasting to all other nodes in the network. The time consuming CRL checking need not be done for each message received. The method proves to be faster in authenticating messages securely. This is suitable not only for VANETs, but for any other network that deploys PKI.

Some background on certificate revocation list checks over HTTP:

“Today I Learned that OCSP over HTTP is a (mostly) good thing. Kind of.

During my work day I’ve been getting a lot of these requests from Firefox when visiting HTTPS sites. Curious, I captured one and looked inside. They are publicly visible HTTP requests for a Certificate Revocation List status of the site in question. This seems insecure, but the payload is CA signed per the RFC, and only contains info related to certificate revocation. Since the initial root CA certificates are pre-loaded into your OS and browser, the attempt to get revocation notices could in theory be blocked but not forged. At worst, an attacker could prevent you getting CRL info and cause your browser to continue trusting a previously revoked certificate for a site that is presumed secure.

There’s been some debate in the past over whether CRLs are an imperfect creation or an actual hindrance. Google took some heat a few years ago when they decided to remove certificate revocation checks from the request dispatch in Chrome, instead relying on software updates because of the claimed weaknesses in the CRL mechanism. This omission increases the window of potential vulnerability from minutes or days to weeks or months, depending on how quickly app updates are rolled out versus how timely the CRL would have been updated.

Firefox, on the other hand, still performs these checks. In the clear, divulging user agent info. But then, so does every other HTTP web request. For this part, the RFC states “Where privacy is a requirement, OCSP transactions exchanged using HTTP MAY be protected using either TLS/SSL…”  So, while these requests could encrypted, they wouldn’t be very much more secure, but they could be made more private.

Still, not all HTTP requests are bad. Content matters. Security is hard. Wireshark is your friend!”
