Network Discovery tools

Posted by strom on May 31, 2007

Enterprise networks have gotten so complex that it is rare that any single person knows exactly what is connected to them. That could become an issue, particularly if someone brings an infected PC or if disaster strikes and a portion of the network goes south. The solution is a variety of network discovery tools and techniques, some simple and cheap, others less so, to keep up with your knowledge of what’s on the network.

Email Koyaanisqatsi

Posted by strom on May 31, 2007

When someone sends you an email, when should they expect a reply? Within an hour? A day? It is a simple question, but the answer (and you can send them to me via email if you’d like) isn’t.

I think most of us try to respond within a business day, and if we get the email early enough, by the close of that day too. It is a pretty good rule of thumb.

But then some of us expect a response even quicker, and get annoyed or impatient of the delay. To me, this represents something out of balance, like some scenes from the movie Koyaanisqatsi. (Little ironies department: I now live about a mile from the former site of Pruitt-Igoe made famous in the movie.)

I was talking to a colleague yesterday about how she often replies to her emails late at night, after her husband has gone to sleep. It made me think about how often I reply to emails in the early morning, before my own wife awakes.

And how many of us can’t leave the laptop home when we go on vacation for fear of the massive email pile-up that will await us upon our return? Or who can’t help ourselves but “multitask” during meetings and clear our inboxes when we are supposed to be part of the meeting itself?

There are some that are hyperactive email responders, carrying BlackBerries and being reachable 24×7. You know who you are.

Is this healthy? I am beginning to wonder.

The irony is that I have come full circle on email responsiveness. Back in the early days of my own email use, I tried to respond to every email that I received within a few hours. This is the early 1980s, when the Internet was still a DoD science project, and few people had the ability to send messages between corporations, let alone across the world. It was still a novelty then.

In the early 1990s, I had an Internet-reachable email address, actually several. When I started Network Computing magazine, we were one of the first magazines to include email addresses of the authors for each article, which was also novel concept then. Now you can find them for the bylines in my local paper. I was also an early user of the BlackBerry precursor, called Radiomail. I remember one time pulling over at one toll plaza on the Garden State Parkway to answer some emails. A curious cop came over and was wondering what I was doing.

Back when Computer Associates (now called just CA) first implemented their email network, they actually turned the system off for several hours during the workday because they wanted their staff to get work done. This was before various executives were caught cooking the books, so I guess it worked too well. They eventually stopped doing this, and now email is available 24×7, just like everywhere else.

The email landscape sure has changed since then and what was novel is now de rigueur. Today most of us think nothing about emailing people that are halfway around the world, and of course now I get spam in about a dozen different languages, if I could figure out the character sets that come into my inbox.

The trick to being successful with email can be summed up with one word: balance. Or getting back into email balance.

“I do however still get a chuckle by those who complain they can’t get work done at the office, yet are sending personal emails out all day long,” says Rich DiGirolamo, who writes a very amusing email newsletter and is a professional keynote speaker. “Some of us make every effort to answer every email within twenty-four hours, but at times we need to prioritize them. Yours just may not be as important to me as you think it is. But it will get answered, I promise.”

I think that is a great strategy. I recommend setting aside some time every day to read your emails, and perhaps a separate time to write replies. But don’t let it bleed into the entire day.

Maybe we need an email rehab center in Malibu to help those that need to get their lives back into balance.

How to prepare your network for VoIP

Posted by strom on May 30, 2007

Enterprises wanting to get the most use of Voice over IP need to know the steps involved in hardening their network and Internet infrastructure to get the best results out of their digital voice deployment projects. In this article published today by Computerworld, I talk more about what you need to know, including:

  • What is your present Internet connection and how much bandwidth will you need for voice?
  • What kind of wiring is in your walls?
  • Will you need to support remote users that are working outside your headquarters office?
  • What will you do with your existing analog phones?
  • Can you keep your existing inbound phone numbers?
  • Do you need to upgrade your network switches and routers?
  • Do you really need to own your own IP PBX?

At my local library, they have poured glue in the USB ports of their computers, to keep people from inserting USB key drives and infecting them. Such extreme measures aren’t necessary, thanks to the miracles of software from Safend Technologies.

Posted by strom on May 24, 2007

I have been working with Ziff-Davis’ ITLink social networking site, adding content that is geared towards the reseller community. Today’s Channel Chat podcast is with Karen Hartsell, the director of world-wide channel marketing for PGP Corp. I spoke to her about how VARs can sell encryption, some of the things that she looks for in picking VARs, and recent changes to PGP’s channel program.

Time is ripe for VARs to sell encryption

Posted by strom on May 24, 2007

There has never been a better time to sell encryption: a perfect storm of regulatory requirements, improved technology, beefed-up channel programs and just increasing general paranoia has combined to make for a compelling case to protect your clients’ data. VARs have three different opportunities when it comes to selling encryption products and services: whole disk encryption for laptops and desktops, database encryption, and email encryption.

In this story for eWeek’s Strategic Partner edition, I talk more about these options.

How Network Forensics Can Help Human Resource Compliance

Posted by strom on May 21, 2007

Something wrong is happening on your network. Call it human nature or simply a few bad apples, but unless your organization is miraculously different from all others, someone is leaking information, someone else is dabbling in porn, and someone else is probably doing a handsome business on eBay—on one of your servers.

Your organization has policies about this—and your industry may have regulations that pertain, as well. You need to ensure these policies are complied with—or you need to collect evidence to take action when they’re not.

When you suspect something is wrong, do you have the means to conduct an investigation? How do you collect evidence—digital evidence—when there are so many channels of communication (email, Web mail, IM, etc.), and so many places to look on your network?

I review these and other issues for a white paper for WildPackets that you can download here.

Posted by strom on May 21, 2007

As part of a review of unified threat management (UTM) products for Techtarget, I took a look at the Sonicwall  5060 box. Here I demonstrate the configuration options available using an animated voice-over “screencast” that is pretty nifty.
