DoD APLITS Requiring Client Certificates

Blog, DoD UC APL

In a previous post, I warned everyone that accessing the DoD’s Approved Products List Integrated Tracking System (APLITS) will require a client certificate. Currently, the APLITS system accepts the use of a DoD Common Access Card, or CAC, to access. However, this limits access to the APLITS site to only DoD civilian, military and contractor

OSPFv3 Authentication Trailers – IPv6 Capitulations

Blog, IPv6, IPv6 Security

A few weeks ago, the IETF updated the newest in a long line of what I like to call “IPv6 capitulations.” Going on a rant here – the IETF fought long and hard to have a robust, secure, and interoperable protocol with IPv6. This is one of the many examples where it is being systematically

DoD UC APL Testing and Windows Security: DoD IAVerify

Blog, Cyber Security, DoD, DoD UC APL, News

Completing the hurdle of DoD Unified Capabilities Testing (UC APL) in a decent amount of time is already a challenge. However, if you have Microsoft Windows workstations (Vista, 7, 8, etc) or Windows Servers (2008, 2008 R2, 2012, etc), then your validation, hardening and testing gets so much more complicated. For the DoD, Windows security

DoD UC APL Site APLITS requiring 2-Factor Authentication

Blog

Actually, the site will require CAC-only (DoD Common Access Card) logins starting 28 March. After that time, no vendors, sponsors or testers can login to the site using a user name and password – ever. What Does This Mean for You?* If you are a DoD contractor, civilian or uniformed military you will not be

Stopping Amplification DDoS Attacks – BCP38 Basics

Blog, Cyber Security, IPv6

The key to any secure network in stopping 100% of UDP-based DNS amplification DDoS attacks is simple: follow BCP38. You ask, “but it’s 2014, and BCP38 came out in 2000, why bring it up?” Well, simply not enough networks are following the Best Common Practice. Why I Bring Up BCP38 This last week saw the

DNS Part 2: Learning Dig

Blog

A few months back, I wrote an article called DNS for Network Engineers. Basically, it is a back-to-basics look on what each of the DNS record types were, and a few examples of what they looked like using Dig. Well, the feedback I received was a desire for more Dig. So I give you: Learning

Cisco OSPFv3 AF Authentication Fixed!

Blog

OSPFv3 AF Authentication is finally fixed! Unless you are a regular follower of this blog, you may not have heard that Cisco’s OSPFv3 with Address Families (AF) Authentication support was broken. By broken I mean it took down OSPFv3 adjacencies. Not good. Read here for that article. Anyway, I have been using the IOS-XE version

DNS: Back to Basics for Network Engineers

Blog, Cyber Security, IPv6, IPv6 in the Government, IPv6 in the Industry, IPv6 Security, Routing and Switching

Speaking with quite a few network engineers in the last few months, I was shocked by the lack of real understanding of the Domain Naming System (DNS). It shocked me because it is the singular application functionality that is entirely network-based. Meaning that DNS is the foundation of the Internet, and from their perspective, should
