Top Stories by Gilad Parann-Nissany

The US Federal Communications Commission has recently reported that "theft of digital information has become the most commonly reported fraud, surpassing physical theft." Businesses can do a lot to protect themselves. The FCC issued a Tip Sheet for small businesses to promote employee security training, firewalls, securing of WiFis, and more. But for business operating in (or migrating to) cloud environments; data security, cloud computing security issues, and challenges take on  new meanings and require new strategies. Security in the Cloud: Unique Challenges In the cloud, data security poses new risks and challenges. We are no longer concerned just with burglars breaking into our offices to steal computers, but rather with the data belonging to complete systems deployed to the cloud. When using public cloud infrastructure like that of AWS, VMware, Microsoft Azure... (more)

Startup Debuts with Encryption for Cloud Computing

Israel-based startup Porticor launches this week with technology aimed at giving enterprises a way to encrypt data held in cloud computing services, including those from Amazon and Rackspace. Porticor Virtual Private Data is focused on protecting data at rest in cloud-based computing centers where customers rent disk space or servers, says Gilad Parann-Nissany, Porticor’s co-founder and CEO. What Porticor is doing that’s distinct is relying on a so-called “split-key” method in which the service to encrypt and decrypt doesn’t work unless both pieces of the key are together. The ...

Transparent Data Encryption in the Cloud

Transparent Data Encryption (TDE), sometimes also called Transparent Database Encryption, is one way to encrypt database content. TDE offers encryption at a column, table, and tablespace level. This makes TDE one of the more highly configurable ways to encrypt database content, though some of these configuration options come with a performance price. While TDE is well known in the Data Center, bringing it to the realm of Cloud Data Security does involve some new technical and operational questions. Database products that support TDE TDE is available as an “enterprise level” feature... (more)

Cloud Encryption Best Practices

Cloud encryption keeps coming up as one of the hottest topics for enterprises migrating to the cloud. IT departments are constantly pushed to cut costs and utilize compute resources more efficiently, hence cloud computing is the natural evolution, yet at the same enterprises cannot compromise on cloud security, and cloud encryption should be considered high on the list as it segregates and “hides” your data from other virtual entities hosted on the same physical cloud infrastructure. What’s my cloud provider’s encryption approach? Cloud data security and cloud encryption comes in ... (more)

HOMOMORPHIC ENCRYPTION FINDS A HOME IN THE CLOUD

    (Originally posted by Lori Macvittie on rishidot.com) Porticor, which earlier this year unveiled its split-key encryption technology for securing cloud data has taken the next step in its quest to assure users of the security of data in the cloud. In addition to adding VMware private cloud to its portfolio of supported environments (previously it supported only Amazon environments) it announced that it has introduced homomorphic encryption into the equation, which further secures one of the least often (and yet most important) aspects of cryptography – the security of crypt...
