Cloud computing brings many advantages including elasticity, flexibility, and pay-per-use. But when looking at cloud security, and specifically encrypted cloud storage the picture is much more complex. Cloud security (in IaaS and PaaS scenarios) is a shared responsibility. The cloud provider is responsible for securing the datacenter premise, the virtualization layer, and the Host OS, but it is the cloud customer’s responsibility to secure the host OS, work with an encrypted cloud storage and secure the application level. The missing piece by shel silverstein Cloud data security threats Some aspects of securing virtual servers and storage are not dramatically different from securing a physical server and the same basic rules still apply.  Enforcing a strong access control policy, disabling unnecessary ports, and hardening the application layer are still valid and nec...

Cloud Security Solutions for Hybrid Clouds

When large enterprises move to a public infrastructure cloud (such as Amazon Web Services or others), it is a gradual, and often times, carefully measured process. Large enterprises strive for 100 percent certainty that the migration process will not impact the business; therefore, they’ll usually start slowly, by migrating one application or process to the cloud.

But once even part of the business is in the cloud, the need arises for cloud... (more)

Cloud Encryption and Key Management for Software Vendors

A software vendor can make use of the IaaS provided APIs to automatically add servers, disks, back... (more)

Encrypting Data Held in the Cloud

More and more enterprises now rent space or servers on the cloud to store data. However, the fact that such data remains outside the ambit of the enterprise’s security system and invisible to the enterprise poses a serious security headache. Porticor Virtual Private Data, an Israeli based start-up now offers technology that allows organizations to encrypt data held in the cloud. The service, which includes a Virtual Appliance and an agent software, offers standard AES 256 or Blowfish encryption that has a maximum key length of 2048 bits.
