Last week, I received this in an email from Google:
In order to continue to improve our products and deliver more sophisticated features and performance… we will be phasing out support for Microsoft Internet Explorer 6.0 as well as other older browsers that are not supported by their own manufacturers.
It’s about time, and not just for those reasons. (more…)

This week’s Data Security Podcast had two items that really piqued my interest. The first was an article about an Ohio hospital which suffered data loss due to a malware infection. The malware was sent by the boyfriend of a hospital worker. Apparently he intended to follow his girlfriend’s movements on the Internet on her home PC. What he did not count on was her opening her email at work, and subsequently infecting a hospital computer. Quoting the PC World article,
“Between March 19 and March 28 the spyware sent more than 1,000 screen captures … via e-mail. They included details of medical procedures, diagnostic notes and other confidential information relating to 62 hospital patients. He was also able to obtain e-mail and financial records of four other hospital employees as well…”
This incident goes a long way to show that the biggest threat can often come from inside. Yes, while the boyfriend was the root cause, had the hospital employee not been allowed to access her personal email from work, her system would not have been infected in the first place.
In a separate news article, Panda Security reports that a hacker site is offering to crack Facebook accounts for the low low price of $100. Setting aside the question of whether the site is a “legitimate” hacking site (who’s to say they won’t just take your $100 and walk away?), I found it interesting that a Facebook account is now worth 3 times the street price of a social security or bank account number, which my sources say are going for $20-35 a piece.

Readers of my personal blog or listeners to the Fresh Ubuntu Podcast will know that I have long been a proponent of Linux as an alternative to Windows, and now, more than ever, this should be a reality at your organization. What’s changed? Last year, Ubuntu, the leading desktop Linux distribution today, addded a package called Likewise-Open, from Likewise Software, Inc., to their software repositories. This means that, with just a few clicks, it is possible to make a Linux desktop computer log in to your existing Windows Active Directory system, without having to make separate user accounts for it.

Today I am reviewing a tiny, free, handy piece of software for end-users: Rubber Ducky System Monitor by MimarSinan International. The program is a tiny application which gives even a novice user a simple, easy to read display which tells them how busy their system is and identify potential problems. (more…)

We sometimes get support requests from frustrated clients who are in some way prevented from accomplishing a task because of system security policies. Unfortunately, they sometimes think that we have done this deliberately to make their job difficult. One of my jobs as a security professional is to explain to my clients just what security measures we take to protect them, and why. Today, I’ll try to explain how web content filters do their job and why they are important. (more…)

Symantec Ghost is a useful application for what’s known as “imaging” or “cloning” computers. It allows you to copy a single computer’s hard drive contents to multiple machines at once so you have a base Windows install that’s exactly the same on all of the machines. The only difference is the uniquely identifying information about the machines (computer name, Hardware address, etc.).
Recently one of our client’s Ghost subscriptions came up for renewal. While Ghost does what it’s designed to do well enough, we were wondering what other options there were out there in the world. Enter FOG. (more…)

Electronic greetings cards are a fad that, sadly, has not yet passed and is still quite popular. These things are bad for several reasons, which I’ll outline in today’s post. (more…)
