What the Google/China Hack Means to You

Sunday, January 17th, 2010

Friends and listeners to the Fresh Ubuntu Podcast will know that I frequently raise concerns about Google and the information that it acquires about all of us. My concerns normally are along the lines of “just imagine what Google can do with all of that information.” However, I’ve never brought up what could be an even bigger concern: “What if someone else were to get a hold of all of that information?” (more…)

Software Review: Thunderbird 3

Tuesday, December 15th, 2009

After a long period of apparent stagnation, Mozilla Messaging, a wholly owned subsidiary of the Mozilla Foundation, has released the long-awaited Thunderbird 3 – its free, open-source email client. Thunderbird has been my favorite email client for several years now, as it does everything that Outlook Express or Windows Mail does (as far as I am concerned) and has a better track record for security, runs faster, and works on Windows, Mac OS X, and Linux.

Further Evidence That Personal Internet Use Should Be Restricted at Work

Wednesday, September 23rd, 2009

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.

Why Electronic Greeting Cards Are Bad

Friday, June 26th, 2009

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…)

Using Microsoft Outlook to Access Other Users’ Mailboxes

Friday, June 12th, 2009

If you have a Microsoft Exchange server at your business, Microsoft Outlook has the ability to access more than one mailbox at a time. This is a useful feature if multiple users need to share access to the same email address, or if someone needs to cover another person’s email (when an auto-responder won’t suffice) while on vacation.   (more…)

What is “Unified Threat Management?”

Friday, June 5th, 2009

“Unified Threat Management” is a buzzphrase (that is, a few buzzwords strung together) heard a lot in networking and network security. Essentially, this is something (usually a device) which combines several network security services, including email filtering, web content filtering, firewalling, intrusion detection/prevention, and others. A UTM device can provide other services as well, such as VPN (Virtual Private Networking) support, to allow your remote workers to securely connect to your office. UTMs frequently seen in small businesses because they (usually) carry a lower cost than purchasing and managing several separate devices or software packages to perform the same functions. (more…)

Keep Your E-mail Server From Being Blacklisted

Monday, April 27th, 2009

For many small to mid-sized businesses that have their own on-site e-mail server, it is a common practice to use a router and a single public Internet address (the one given to them as part of the basic business-level DSL or cable Internet package) to serve their entire network. Behind this router sits the e-mail server, and desktop computers. (more…)
