FYI, thanks for bearing with me these couple of weeks. I spent a week in a lab with no Internet access at all, which made blogging life (and actually ALL life) very difficult. Upon returning, I’ve been in the process of following up on the DNS vulnerability which has now been accidentally released. And, as I mentioned in an earlier post, I’m smack in the middle of moving this blog to a new, fuller-featured platform. (more…)
No CommentsIt’s been a day since the public announcement, so by now you’ve probably heard about the DNS issue. The bug was found earlier this year, but the discoverer (Dan Kaminsky) and team worked fervently with leaders of the technology industry to create patches for all platforms before the big announcement. And- kudos to them all for keeping zipped lips until the problem could be contained (despite all the heckling and harassing).
You can find out a little more right now- I’m including some links below for you to read more.
If you don’t know what DNS is or why you care, see the bottom of this post for a little background info.
As for the real deal on disclosure- you’ll have to wait for Black Hat in August. I’ll be there, along with other members of the Security Bloggers Network (a (non-exclusive but highly visible and well-respected) security bloggers channel for Black Hat and RSA). I’m sure you’ll see *plenty* of post-Black Hat blogs, tweets and podcasts recapping the story.
Hear the buzz…
What is a DNS Server? DNS are servers throughout the Internet (and inside networks) that resolve domain names (ie www.SecurityUncorked.com) to the IP address of the hosting server. The idea is, if you can trick a DNS server, your request for ESPN.com may just take you to a malicious site where you’ll be immediately infected with a virus, malware or other undesirable creepy Internet-bred monster. They’ve found a bug that could be exploited to do just that.
What do we do? It’s not the end of the world. For now, know that almost all DNS servers need to have a patch installed to protect them from this vulnerability. It’s pretty universal and every manufacturer is on board and offering a patch as of yesterday, July 8th.

No CommentsI have a note to all network hardware vendors…
Dear network vendor,
As someone that is forced to configure and implement security on your hardware, I would greatly appreciate stable code and properly functioning features. Unfortunately, I cannot always choose the hardware my customers are using in their infrastructure. However, if you would like for me to recommend they continue purchasing and using it, then the product must demonstrate to me that it is: capable, reliable, predictable and well-documented. If your product is not meeting these requirements, I’m forced to recommend other solutions to your (current) customer.
Stable Code. If I have to spend 2-6 hours per implementation working through your product’s bugs, and then must either spend time on a support call or spend time getting packet captures to prove to you it’s not working, I am not a happy camper because you’re slowing down my progress. Your customer is not happy because they’re paying for that time and I’m not cheap.
Features. Don’t publish in technical documentation that your product, or code can do something, only for me to find out later that it cannot. On-site in the middle of an implementation is not the time to architect Plan B. Let me know before, either through technical docs, white papers, best practices or release notes. I do read those. If you want to bend the truth, do it the marketing fluff, not my technical documents.
Documentation. If your product does do what you say it does, then please do document and explain the concepts and procedures. Examples are good, but explanations are mandatory. A correct CLI reference is always lovely as well. If there are got’chas or tricks, please also document those. Again, white papers or release notes are fine. Having to track down the one security engineer from your company that holds the magic key is not practical, nor scalable. Plus, he may be on vacation during my install, which would make me irate.
Support. If your product is not functioning or performing as expected, do NOT expect your customers to have a current maintenance contract to address a known issue or bug (or an un-known issue or bug for that matter). If they found a bug for you, you should probably give them a maintenance contract for a year… or two. If you don’t let us call support, I will find one of your pre-sales engineers and we will use him or her for post-sales support, which is not what you want them to do. But that’s your problem, not mine.
I believe that sums up the major issues. Specifically, I am interested in security, RADIUS, SSH, SNMP, DHCP and 802.1X functions. Before you add another bell or tweak another whistle, please make what you have works… consistently. That should be first, so it’s my Feature Request #1.
Respectfully,
jj

1 CommentYes, you read it right- Symantec (as in the software vendor) has a network-based (as in the hardware) NAC. Once you get over the title, keep reading.
If you read my blog, or know me, you probably know I do NOT like software (and it usually doesn’t like me). So, I’d be the first to jump on the ‘anti-software-peer-based-NAC’ train, but I think we have to be informed before we jump to conclusions and hop on any trains. (more…)
2 CommentsI promised a while ago to let you all in on some of the various projects I’ve been working on over the past few months. One I haven’t shared with you yet is my participation in contributing as a SME to the official (ISC)2 courseware for CISSP certification.
It’s a huge undertaking with 10 domains chock full of every security topic you can imagine, 20 contributing SMEs from all over the worls, a handful of editors and 1 man to bring it all together. Our team leader, Dean Bushmiller has been the Project Manager for both versions 8 and 9 of the CISSP courseware and does an amazing job.
Each of the SMEs and editors have put a lot of thought and time into the materials, in an effort to create the best and most relevant content, topic arrangement and flow possible. You’ve seen how big these books are- that’s a lotta’ stuff to pull together and I admire the group, especially the domain wranglers and Dean, for keeping it all on track.
It’s a strange and exciting project. I can’t say it’s completely foreign to me, many years ago I created content for advanced Microsoft Office courses and developed official Computer Competency Training for K-12s for use in schools here. However, a project with this much mass is definitely unique.
So, that’s another little project I’ve been working on for the past several months… and will be continuing for several more. On those occasions I drop off the face of Blog World, it’s sometimes because I’m using every free moment to try and keep up with these types of projects and deadlines.
