HP: When 'Good' Security News Isn't
HP is just the latest in a long list of security vendors touting its comprehensive cyber security report showing what the most recent threats are, how they’ve changed and--sometimes subtly, sometimes not--how their security technology can protect you. But its study is another illustration of how the tech industry is constantly playing catchup with the criminals. HP’s report also illustrates how seemingly good news can turn out to be bad.
WAN Optimization Helps Networks 'Evolve'
Networks are asked to do a lot these days--from moving video and voice to connecting mobile devices to delivering applications through a browser--but the basic architecture of a WAN hasn’t changed much over time, says analyst Zeus Kerravala. Enter WAN optimization, whose goal is to improve performance to deliver apps from the cloud that look as good and perform as if they were natively installed on the endpoint device.

Toward More Reliable Wireless With AirMagnet Enterprise 10
February 27, 2012 04:40 PM
Posted by Lee H. Badman
If the phone isn't ringing, then your wireless users must not be feeling any pain, right? That can be a dangerous assumption in large, complicated wireless networks. Some issues may not be crystallized enough to raise your clients' ire, but the fact remains that performance is degraded. AirMagnet's latest Enterprise version wants to make hard-to-find problems more obvious even as the WLAN gets ever more complex.

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.
