Securing big data: Architecture tips for building security in

Since “big data” is a hot topic these days, there’s no question an increasing number of enterprise infosec teams are going to be asked about the security-related ramifications of big data projects. There are many issues to look into, but here are a few tips for making big data security efforts more secure during architecture and implementation phases:
  1. Create data controls as close to the data as possible, since much of this data isn’t “owned” by the security team. The risk of having big data traversing your network is that you have large amounts of confidential data – such as credit card data, Social Security numbers, personally identifiable information (PII), etc. -- that’s residing in new places and being used in new ways. Also, you’re usually not going to see terabytes of data siphoned from an organization, but the search for patterns to find the content in these databases is something to be concerned about. Keep the security as close to the data as possible and don’t rely on firewalls, IPS, DLP or other systems to protect the data.
  2. Verify that sensitive fields are indeed protected by using encryption so when the data is analyzed, manipulated or sent to other areas of the organization, you’re limiting risk of exposure. All sensitive information needs to be encrypted once you have control over it.
