12 Steps to Bring Your Own Device (BYOD) Success

White Paper | April 16, 2012

IT departments have multiple opportunities and challenges as a result of the Bring Your Own Device (BYOD) invasion. The most common opportunity is to reinforce enterprise network security from both the inside and the outside. Supporting BYOD also offers more monitoring and tracking of activities that provide a more detailed view of network traffic flow. Alternatively, it will be a challenge for some IT departments to give up control over which devices may access their enterprise network. Another challenge will be to have the users doing configurations for network access, which adds human error to a crucial part of the process. The opportunities and challenges BYOD represents are real. Enterprises must make their network infrastructure BYOD ready to meet the onslaught.

What Kind of Network Am I On?

Article | March 01, 2012

Good question! There are lots of networks, so I’m sorry to say that it depends. Let me explain. The smallest computer-based networks are usually PANs or Personal Area Networks. They can connect a wireless keyboard, mouse, or other devices to a computer. You may find them wirelessly linking a printer to your computer. You may have noticed these all include wireless connections. A PAN most often uses wireless technologies like infrared and Bluetooth, so it is really a WPAN (Wireless Personal Area Network).

The 5 Phases of Hacking: Covering Your Tracks

Article | Aug. 30, 2011

An attacker needs to destroy evidence of his presence and activities for several reasons like being able to maintain access and evade detection (and the resulting punishment). Erasing evidence of a compromise is a requirement for any attacker who wants to remain obscure and evade trace back. This usually starts with erasing the contaminated logins and any possible error messages that may have been generated from the attack process.

Are Production Server Reboots Standard Changes?

Article | April 27, 2011

I attended a meeting this week with a customer of mine and a potential new vendor. The new vendor was there to pitch his configuration and setup service offerings for a specific ITSM toolset. My customer has already had one bad experience with an ITSM tool configuration vendor who promised one thing and delivered much less. He ended up with a tool that’s minimally used and not configured to match his business needs. He’s looking for a vendor that can understand his business needs and priorities and quickly help him get his tool configured and working in a short time frame. Then the topic of standard changes came up. My customer asked for examples of standard changes. The vendor responded, “Server reboots are an example of standard changes.”
