When people talk about cloud security it can mean either 1) security for the cloud—security that protects your cloud initiatives, like protection for virtual machines or data stored in the cloud; or 2) security from the cloud such as Security as a Service that uses the cloud to deliver some aspect of protection, like hosted…
Read MoreTraditionally businesses have focused their IT security on perimeter defense—blocking threats before they enter the network. This protection is still important. But with today’s cloud computing, mobile devices, and advanced persistent threats (APTs), businesses need security that protects their data wherever it travels and in whatever type of device it resides, requiring new data-centric security. …
Read MoreFor the last few months, we’ve been conducting a cloud, virtualization, and VDI security survey of 1200 IT professionals from larger companies in 6 countries around the world.

Read MoreThis is pretty cool. I gave a talk last week at the Glue Conference in Denver about how ambient clouds ( http://cloud.trendmicro.com/good-clouds-evil-clouds-why-microsoft-has… )work and even used Skype as an example of a massive-scale ambient cloud.
This case raises some very important new questions around ambient clouds.
With the launch announcements of various Google Chrome OS netbooks, the focus of the press and security companies alike is beginning to take a closer look at the security promises made and also at some of the more ’media friendly‘ statements such as, “…users don’t have to deal with viruses, malware and security updates”.
Last Thursday, April 21, 2011 Amazon Web Services Elastic Compute Cloud (EC2) had an outage that impacted multiple Availability Zones. Thursday morning, Amazon issued a status update indicating that the outage was based on problems with replication mirroring: “This re-mirroring created a shortage of capacity in one of the US-EAST-1 Availability Zones, which impacted new EBS volume creation as well as the pace with which we could re-mirror and recover affected EBS volumes. Additionally, one of our internal control planes for EBS has become inundated such that it’s difficult to create new EBS volumes and EBS backed instances.”

Read MoreDedicated Instances are Amazon EC2 instances launched within your Amazon Virtual Private Cloud (Amazon VPC) that run hardware dedicated to a single customer.
Of course, the humor here is that Amazon didn’t explain which hardware it was referring to. If you compare it to an enterprise server in a private data center, it’s clearly less secure (unless you applied cloud specific security and encryption tools perhaps). But if you compare it to existing hosting offering, it’s no less secure than enterprise grade hosting has been for a decade.

In a recent eWeek interview, Citrix CTO Simon Crosby described Conficker malware as “the world’s largest cloud.” He’s right. Cybercriminals use Conficker to create massive clouds of remotely-controlled PCs capable of carrying out a variety of cyber-attacks, including DDoS (Distributed Denial of Service) attacks on a scale larger than any centralized cloud provider could. We…
