Why is double opt-in still not used by everyone?!

Out there in the big wide world there are, beside me, unfortunately, a few other people named “Mark Gibbs” and a number of these individuals don’t know their Gmail addresses. This is a problem as I am the proud owner of “[email protected]” and have been since the start of Gmail while they are not. The trouble with these people is they keep giving my Gmail address to organizations they deal with and more than a few of these organizations fail to do the one thing that they should be doing when it comes to building an email relationship with a customer: Verifying the customer’s email address.To read this article in full or to leave a comment, please click here

Dismal PC business contraction continues; no bounce yet from Windows 10

As expected, Windows 10 provided little if any bounce to PC shipments in the just-concluded September quarter, researchers at IDC and Gartner said yesterday. "Not in terms of driving volume, no," said Loren Loverde of IDC in a Friday interview when asked about Windows 10's impact. "The main inhibiting concern has been the continuing free upgrade." Rival research firm Gartner concurred. "The focus of the Windows launch in the quarter was to upgrade to Windows 10 on existing PCs, rather than ship on new PCs," the company said in a statement. Both IDC and Gartner pegged third-quarter PC shipments as down from the same period in 2014, although they differed slightly on the extent of the contraction. IDC said that shipments declined 11% year-over-year, while Gartner said it was closer to 8%. IDC put shipments at 71 million, Gartner, at 74 million. Part of the difference is how each defines the category: IDC does not include tablets with detachable keyboards, such as Microsoft's Surface Pro, while Gartner does.To read this article in full or to leave a comment, please click here

Dow Jones & Co. discloses breach, incident likely related to Scottrade

On Friday, in a letter to customers, the CEO of Dow Jones & Co. disclosed a data breach affecting 3,500 people. Based on public details, the incident seems similar to a breach reported by Scottrade last week that impacted 4.6 million investors. In his letter, Dow Jones Chief Executive William Lewis said that law enforcement officials informed the company about the potential breach in late July. After bringing in outside help, an investigation turned up a confirmation that the systems housing the customer data was accessed – but there is no proof that data was exfiltrated. The investigators also determined that the attackers had access to the system between August 2012 and July 2015.To read this article in full or to leave a comment, please click here

Fabric View

The Fabric View application has been released on Github, https://github.com/sflow-rt/fabric-view. Fabric View provides real-time visibility into the performance of leaf and spine ECMP fabrics.
A leaf and spine fabric is challenging to monitor. The fabric spreads traffic across all the switches and links in order to maximize bandwidth. Unlike traditional hierarchical network designs, where a small number of links can be monitored to provide visibility, a leaf and spine network has no special links or switches where running CLI commands or attaching a probe would provide visibility. Even if it were possible to attach probes, the effective bandwidth of a leaf and spine network can be as high as a Petabit/second, well beyond the capabilities of current generation monitoring tools.

Fabric View solves the visibility challenge by using the industry standard sFlow instrumentation built into most data center switches. Fabric View represents the fabric as if it were a single large chassis switch, treating each leaf switch as a line card and the spine switches as the backplane. The result is an intuitive tool that is easily understood by anyone familiar with traditional networks.

Fabric View provides real-time, second-by-second visibility to traffic, identifying top talkers, protocols, tenants, tunneled traffic, Continue reading

Can $1M in damages be accurate in a website defacement?

Corporate security pros should note that journalist Matthew Keys was convicted this week of changing a headline on the LA Times Web site, a case that may help define what can be included when a toting up damages caused by hackers. The bill cited in court came to $929,977 for the cost of changing back the altered headline, which stayed live for less than an hour, but also the cost of assessing what other damage was done and fixing it, which took months. You can read details about the case here and here.To read this article in full or to leave a comment, please click here

Old-school sexting, as in circa 1969

Sexting among today’s teenagers was the subject of an email string this morning that eventually took a turn down memory lane, courtesy of a long-time friend who wouldn’t make up stuff like this: “Which reminds me of a story from 9th grade (1969 or ‘70). I was outside the high school with a couple of friends one morning before homeroom when we noticed some kind of small piece of paper falling from a second-story window. We went over and picked it up, and it wasn’t a piece of paper after all! Rather, it was a still-developing Polaroid of a kid’s (penis) with the handwritten caption, ‘(Not-to-be-named-here kid’s penis.)’  Technology really has come a long way.”To read this article in full or to leave a comment, please click here
