IT Certifications

My buddy, Mike, sent me an email the other day about “Meaningful Certifications” for the IT field published by Debra Littlejohn Shinder at TechRepublic. A very interesting read that helps me put my future plans in order. Mrs. Shinder is a technology consultant, trainer and writer who has authored a number of books on computer operating systems, networking, and security. I wanted to share it with all of you. I also, looked over Mrs. Shinder’s other books and intend to buy Scene of the Cybercrime: Computer Forensics Handbook.

The Microsoft Certified Systems Engineer (MCSE) certification suffered a bad reputation several years back when numerous people were memorizing the answers to exam questions from “brain dumps” posted by test-takers on the Internet and obtaining the certification without any real understanding of the technology.
Microsoft responded by replacing the knowledge-based multiple-choice questions with a variety of performance-related scenario questions that make it much more difficult to cheat. The difficulty level of the questions was escalated, and the number of exams required to obtain the certification was increased to seven.
The MCSE has consequently regained respect in many corners of the IT community and is a useful certification for demonstrating your expertise in Microsoft server products.

In addition to making the MCSE exams more difficult, Microsoft has created many new certifications. The Microsoft Certified Architect (MCA) is the premiere Microsoft certification, designed to identify top experts in the industry. To obtain the MCA, you must have at least three years of advanced IT architecture experience, and you have to pass a rigorous review board conducted by a panel of experts.
There are a number of MCA programs. The infrastructure and solutions MCA certifications cover broad architecture skills, but there are also more technology-specific programs for messaging and database skills. There are currently fewer than 100 MCAs in the world, making this an elite certification.

The Cisco Certified Internetwork Expert (CCIE) is widely recognized as one of the most difficult to obtain (and expensive) IT certifications. Like the MCSE/MCA, it’s a vendor-sponsored certification, focusing on Cisco’s products.
The CCIE requires that you pass both a written exam and a hands-on lab. To sit for the written exam, you must pay $300 and choose from one of several tracks: Routing and Switching, Security, Storage Networking, Voice, and Service Provider.
You must pass the written exam before you’re eligible to take the lab exam. This is an eight-hour hands-on test of your ability to configure and troubleshoot Cisco networking equipment and software. The lab exams cost $1,250 each. This does not, of course, include travel expenses that may be necessary since the labs are conducted only in certain locations. As if all that weren’t enough, you don’t get to rest on your laurels after obtaining the certification. CCIEs must recertify every two years or the certification is suspended.

Another Cisco exam that’s popular with employers in today’s security-conscious business world is the Cisco Certified Security Professional (CCSP). It focuses on skills related to securing networks that run Cisco routers and other equipment.
You’re required to pass five written exams and must recertify every three years by passing one current exam. Before you can take the CCSP exams, you must meet the prerequisites by obtaining one of Cisco’s lower-level certifications, either the Cisco Certified Network Associate (CCNA) or the Cisco Certified Internetwork Specialist (CCIP).

Security certifications confer some of the highest-paying jobs in IT today, and one of the most well-respected non-vendor specific security certifications is the Certified Information Systems Security Professional (CISSP). The organization that grants the CISSP is the (ISC)2, which was founded in 1989 and has issued certifications to more than 50,000 IT professionals.
Exam candidates must have at least four years of direct full-time work experience as a security professional. One year of experience can be waived if you have a four-year or graduate degree in information security from an approved institution. Another unique feature of the CISSP is that you must subscribe to the (ISC)2 code of ethics to take the exam.
Exam fees vary based on geographic region. In the United States, standard registration is $599 ($499 for early registration). You must recertify every three years by obtaining at least 120 hours of continuing professional education, and you must pay a yearly fee of $85 to maintain the certification. The exam is a six-hour test consisting of 250 multiple-choice questions.

For those who can’t meet the rigorous experience requirements to sit for the CISSP, the (ISC)2 also offers the certification. SSCP candidates need have only one year of direct full-time security work experience. The exam consists of 125 multiple-choice questions, and you have three hours to complete it.
Those who pass the written exam must be endorsed by someone who holds a current (ISC)2 certification and will attest to the candidate’s professional experience or by an officer of the corporation or organization that employs you (owner, CEO, managing partner, CIO, etc.). As with the CISSP, you must recertify every three years by submitting proof of continuing education credits and paying an annual maintenance fee.

Many companies are looking to save money by switching to Linux-based servers, but they need personnel who are trained to design, deploy, and administer Linux networks. There are a number of Linux certifications out there, but the Red Hat Certified Engineer (RHCE) certification has been around since 1999 and is well respected in the industry.
The exam is performance-based. You’re required to perform actual network installation, configuration, troubleshooting, and administration tasks on a live system. You have a full day (9:00 a.m. to 5:00 p.m.) to complete it. The cost is $749.
The Red Hat Certified Architect (RHCA) is an advanced certification that requires completion of five endorsement exams, each of which costs $749 and range from two to eight hours. Like the RHCE exam, they are hands-on skills tests. You must have the RHCE certification to take the RHCA exams.

In addition, for those who have little or no experience in IT, entry-level certifications such as those offered by CompTIA may help you get a foot in the door as you start your IT career.

Linux command line…

Have you ever been stuck thinking, “now what is the command that will let me (fill in the blank)?” Being new to Linux, I have come across this question more than once. I did a little ‘Digg‘ing and found a great site that breaks down about 350 commands to use with the command line in Linux. I have to say that I have already used a couple of them more than once. Hope this helps when you get into a bind.

VMworkstation 5.5 locks up on openSUSE 10.2 and 10.3

I have found out that my VMworkstation locks up on me about every 5 minutes and nothing works.  Not only does the virtual machine lock up, but the WHOLE computer (host and all) locks up and nothing works (i.e. the mouse, keyboard, etc).  I have done some research and found out that if I add hpet=disable to my boot options on grub that my virtual machine and physical machine do not lock up anymore.  I am using a Dell Inspiron E1705, and if you have the same problem as I did.  Try this fix, it might work.

Happy New Year!

Eavesdropping on Bluetooth headsets…

I found this article over at in which Joshua Wright demonstrates how a Bluetooth headset can be hijacked, allowing audio to be sent or received on the device.  All that is necessary is to sniff the device address and use the default pin, and after this the device can be “tapped” (while not in a call) and all audio around the mic can be listened to remotely.

 Here’s the link.
