The WiKID Blog

The WiKID Blog, musings on two-factor authentication, information security and some other stuff.

Update Bash if you are running OpenVPN

You can see the details about the attack. All of the OpenVPN tutorials we have done use "auth-user-pass-verify" on the client side to get the client to prompt for a username and password.  The exploit can be delivered as part of the username.  And it is before authentication.

Obligitory Shellshock post

We are pretty confident that WiKID is not affected by the Bash security vulnerability.  That being said, there should be no harm in running 'yum update bash' or even 'yum update' on your WiKID server.

Moving beyond tutorials

We've written a lot of tutorials over the years.  Some here, some at howtoforge and even NetworkWorld.  We've always believed that it's a great way to contribute to the community, spread awareness and make it easier for admins to secure their remote access services.

Keeping vendors out of AD

We often prattle on about the benefits of having your directory perform authorization, either via NPS for AD or Freeradius for LDAP.  Certainly, for employees where HR can manage users in AD, that makes a lot of sense. Single step disablement.   A recent customer signed on with the opposite needs.  They have non-employees who access their infrastructure remotely via Bomgar and they do not want those users in their directory.
