Security Falling Short When It Comes To Dealing With Growing Cyber Attacks
The total number of network breaches are on the rise, although data loss from cyber attacks has decreased significantly, with customer records continuing to be a primary target for attackers, comprising 89 percent of breached data investigated.
Encryption Key To Evolving Data-Centric Security Model
With data access no longer restricted to the four walls of the enterprise (or branch) and 9-to-5 business hours, enterprises that have traditionally relied on a perimeter-based approach to security are now seeing the benefits of a data-centric approach. Data encryption is paving the way for the transition to data-centric security methods, according to a survey of 506 IT professionals.

Riverbed's Granite Virtualizes Branch Office Storage

Posted by Howard Marks
When Riverbed and others brought WAN acceleration to the market around the turn of the century, many of us hoped that with WAN acceleration we could pull the servers, and the headaches they cause, from branch offices. Unfortunately, many organizations found reasons to keep servers in the branches. Riverbed's new Granite appliance allows organizations to keep servers in their branch offices while eliminating many of the headaches through what Riverbed's calling Edge Virtual Server Infrastructure.

Red Lambda: Security Revolution Or Just Evolution?

Security statistics are depressing. The bad guys seem to be overwhelming the good guys, even when the good guys are well-known security vendors. So when an emerging company, such as Red Lambda, claims to have software that significantly improves the odds for the good guys, you need to pay close attention.

Certificate Authority Compromises Are Global In Reach

There has already been a lot written about the compromise at DigiNotar, GlobalSign and Comodo. One day we will look at the summer of 2011 as the time when the PKI collapsed. That's not hyperbole. The problems with certificate authorities and the inherent weakness they present have been known for years--a fact we alluded to as far back as 1997. Browsers accept certificates as trusted in that they have the signing CA certificate in their local browser store. Browsers do not check that a particular CA is authorized to actually issue a particular server certificate. The trust is universal. That is why the attacks on DigiNotar, GlobalSign and Comodo are so serious and have global impact.

Hacking Everything

Here’s a puzzle for you: What do a new Dodge Ram pickup truck, a digital road sign, a young English lady’s cell phone and a modern lighting control system have in common? They’re not all necessarily made in the same Third World country, if that’s what you’re thinking. But they are all exploitable by virtue of their network connectivity, and the implications can be quite worrisome.

Black Hat Will Once Again Show Our Security Weaknesses
August 01, 2011 11:15 AM
Posted by Jim Rapoza
The most important thing about Black Hat is the reality check it provides on just how insecure everything really is, from computers to networks to mobile devices to industrial and other systems that are now increasingly connected and exposed. And this week’s Black Hat will be no exception, as several scheduled demos will display just how scary some of these security holes can be.
