Cloud Security Alliance releases report on 100 best practices for big data security. The CSA focuses on promoting the use of security best practices within the cloud computing world. The handbook is now available as a free download. The report’s authors recommend strong encryption methods such as the Advanced Encryption Standard (AES), RSA, or Secure Hash Algorithm 2 (SHA-256) for data at rest. For companies working with distributed programming frameworks such as Apache Hadoop, for example, the report recommends using Kerberos authentication or an equivalent to help establish trust.”]
