As a sysadmin, there might be moments where you’ll find the need to change, merge, or rename your domain. Hopefully you name your domain well the first time, but there are still many reasons why you might need to rename a domain, for instance: an organizational restructuring, merger, buyout or expansion. Keep in mind that a rename is not designed to accommodate forest mergers or the movement of domains between forests.

Scarily, in most organizations people have access to much more information than they need in order to do their jobs. With file permissions, it’s easy to mess things up and hard to find and fix problems, especially in large environments. One tiny mistake can cause a ripple effect across terabytes of data, opening up a massive security hole.

Because I’ve boldly assigned myself the task to explain hacking and phishing, I feel compelled to define both terms concisely because, as Einstein’s been quoted countless times, “If you can’t explain it simply, you don’t understand it well enough.”

Customers of EMC’s popular Isilon storage platform have been clamoring for sophisticated controls around their sensitive, regulated content—e.g., SOX, PCI, intellectual property, etc. Varonis is the perfect fit. With our new integration, EMC Isilon customers can audit, manage and protect their human-generated data.

When you’re naming domains, it should be planned as carefully as you would in naming your first child – of course I’m exaggerating – but it’s worth planning carefully. For those of you who fail to heed this advice, we’ve written a tutorial on how to rename a domain. 🙂

With over 55 different fitness wearable devices to choose from, the wearables market has breathed new life into our personal health, providing us with more insight into our sleep patterns, calories burned, blood pressure, heart rate and so much more. In the near future, we may even ingest sensors to gauge how our body reacts to a drug. Adorning ourselves from head to toe with devices that allow us to quantify our health in new ways could bring enormous health benefits.

From a business perspective, distribution lists (DLs) for email communications are a powerful and well-understood concept in IT. And they are popular: Exchange admins have voted with their right-clicks, creating lots of these Active Directory objects in their corporate domains. DLs speed up overall collaboration and leverage the power of groups to answer questions, share and inspire ideas, and announce news. For a number of years, the Linux operating system was developed and maintained by submitting patches via a mailing list.

I’ve received quite a few questions from both new and experienced sysadmins about networked filesystems and file sharing protocols. One question that comes up frequently is “What is the difference between CIFS and SMB ?”

Cindy and I had the good fortune of attending part of the Real World Cryptography Workshop held last week in New York City. We went primarily to listen to Bruce Schneier discuss the implications of the Snowden documents. But we quickly learned from others sessions that there was an underlying context to this conference. Over the last year, cryptography and data security have been completely shaken by malware, and specifically advanced persistent threats or APTs, leading some to say or at least imply that cryptography is dead.
