I recently posted an update about Laura Chappell’s Chappell University Online seminars. I attended one of these seminars today. What a great experience! I always try to attend Laura’s events and always pickup a tidbit that makes my life as a network manager easier. She gives you information about tools you can use to fight the battle of “the network is down”. Most of the time the network is behaving as designed. It’s poorly written applications or too high user expectations that create issues. So, if you want be the expert on fighting the network is “bad” syndrome - check out Laura’s presentations - I did and I learned something new… Continued »

Who hires IT staff anyways? Was it the US CIO or some HR crew?

Recently my fellow ITKE blogger Denny posted a rant against how IT people act in public. I know that his posting does not always apply just to IT folks. A news announcement today makes me wonder about the actions of some IT people and the way they get hired.

Per Network World on Thursday, 3/12/09:

According to a report in the Washington Post, Cisco CCNA Yusuf Acar who is currently employed as the Chief Security Officer (CSO) and/or Information Systems Security Officer (ISSO) of the Government of the District of Columbia, has been busted by the FBI in a federal bribery sting. FBI agents found $70,000 in Acar’s Northwest D.C. home when they arrested him this morning.

The question Brad Reese raises and I think should be considered in this forum is “Who is hiring these people?” Yusuf had no information security certifications or credentials (e.g. CISSP or CISA) to support his position as CSO. Continued »

Tracking down that user/computer that locks AD accounts

With an environment spanning 18+ sites and more than 3000 computers around the globe, you could understand how challenging it would be to track down what device/user might be locking user accounts. There are tools out there that you can pay for that can help do this. However, Microsoft has some free tools that with a little testing and use will permit you to quickly track down where the account is being locked and address the situation.

We had a situation recently where malicious software got onto a couple of machines and attempted to use the Administrator account to login. We have account lockout on our Windows 2003 AD domain, so after the appropriate number of invalid tries the Administrator account was locked out in the domain. This is because the machines were members of the domain and the malware did not distinguish the local administrator account from the domain administrator when attempting to elevate authority. Note that we use least user authority in our environment so the malware was not able to spread beyond these two machines. We suspect the machines became infected due to out of date antivirus signatures.

Unfortunately, the antivirus we use did not alert us to the situation. The way we were alerted was by our Microsoft Systems Center Operations Manager (SCOM) implementation. It notified the SCOM admin that the domain Administrator account was locked. The operations team was then tasked with tracking down what or who was locking this account. This is where the Microsoft Account Lockout and Management Tools came in use and helped isolate the cause. Continued »

administration, planning, tools, reporting, CIO, performance monitoring, Performance, howto, Metrics, blog, education, toolkit, professional

Maybe Bubbletimer mentioned in part 1 is not something that will help improve your professional value in 2009. How about the Printable CEO series then? The tools David Seah offers on his blog seem like great resources to track your goals, tasks and time. Sometimes those we work for wonder what all we do in our positions. We sometimes have to prove our worth to the organizations who pay us. The When is something worth doing? tool that David outlines may help you improve your decision making and therefore your professional value.

What other professional development and/or tracking tools do you use in your job?  Please leave some feedback and let me know what you use or if this Printable CEO made a difference in your job.

Fyodor Releases Nmap Book

Gordon “Fyodor” Lyon, the creator of the must-have tool, Nmap, has released the long-awaited title “Nmap Network Scanning”. This 468-page book  nmap.org) is a required reading for anyone securing a network. I was thankful that Fyodor sent me a pre-release copy of the book, which was a blessing since the content was more in-depth than I’d hoped for. Chapters define scan variations, OS fingerprinting techniques, tips and tricks and the newly-developed ZenMap, the graphic front end for Nmap. “Nmap Network Scanning” should be front and center on your desk for months and years to come! Thanks, Fyodor!

Final beta tests are underway for a planned January 2009 release of the long-awaited Wireshark Certification test. The Wireshark Certification Information Packet (WCIP) should be out at the beginning of the year (sign up to receive the document at www.wiresharktraining.com/certification).I know you’ve waited a long time for the certification and I appreciate your patience - it took me a lot longer to get the questions together and ensure we could deliver via the Internet.

The Only Thing Slower than This Network is Hollywood!

Well, folks… after hearing about the ‘movie’ project for a few years now, you’re probably thinking the darn thing isn’t going to make it out there. You’re probably right, but one more step was checked off last week – the script was finalized. The writers, Joe D’Ambrosia and Tom Teves (Murray Hill 5 Productions) gave me the near-shocking news on Friday. If you don’t know these guys, check out the “Dead Rocker” (appropriate for kids) at www.youtube.com/watch?v=I5aD00UeE9g. I kinda figured out who the murderer was (at least I knew what the main clue was) after watching a second time. Can you/your kids figure it out?

Happy Holidays to All! [Oh... and if you checked out the movie link...no, I'm not a spy and no, my kids don't play soccer.]
