Big Data Systems Get Serious

The use of big data programs such as Hadoop and NoSQL systems is on the rise. Security teams working with the Hadoop teams in their organizations may see an attempt by the latter to convince them that Hadoop security can be handled by built-in mechanisms. These big data staffers may throw a lot of strange names at you and dazzle you with marketing collateral.

Don’t get me wrong: It’s a great thing that Hadoop is beefing up security. But it’s your job to look at the big picture for big data security and compliance. If the organization has standardized a data security and compliance platform, and if that platform supports Hadoop, then the infrastructure is in place to bring Hadoop under your security umbrella.

Making the Most of Security Controls

Work with the Hadoop teams to understand how and when native controls fit the bill. Then identify those cases in which compensating controls are required. It may even be that the security solutions complement each other nicely, allowing the organization as a whole to optimize its data security and compliance infrastructure and processes.

These complementary capabilities may include:

  • Automated compliance workflow to help automate the solution and to obtain auditable sign-off of reports;
  • Policy-based infrastructure that can be used across the data landscape, not just within the Hadoop cluster;
  • Low-impact monitoring paired with rich reporting and investigative capabilities;
  • Separation of duties in which auditing data is separate from the Hadoop cluster and its privileged admins;
  • Use of dynamic data masking and blocking as a compensating control for certain cases; and
  • Analytics of user or group behavior to detect outliers that can help filter out the noise from the activity.

For More Technical Information

For the more technical among you, this recorded tech talk provides a deeper dive into the security implications for Hadoop. For the latest and greatest, see this developerWorks article, which includes an overview of the significant enhancements made for security and auditing in Hadoop environments.  This information can help you learn more about how the platform can extend to big data and beyond.

Overheard at RSA Conference 2024: Top trends cybersecurity experts are talking about

4 min read - At a brunch roundtable, one of the many informal events held during the RSA Conference 2024 (RSAC), the conversation turned to the most popular trends and themes at this year’s events. There was no disagreement in what people presenting sessions or companies on the Expo show floor were talking about: RSAC 2024 is all about artificial intelligence (or as one CISO said, “It’s not RSAC; it’s RSAI”). The chatter around AI shouldn’t have been a surprise to anyone who attended…

3 min read - There are over 17 billion internet-connected devices in the world — and experts expect that number will surge to almost 30 billion by 2030.This rapidly growing digital ecosystem makes it increasingly challenging to protect people’s privacy. Attackers only need to be right once to seize databases of personally identifiable information (PII), including payment card information, addresses, phone numbers and Social Security numbers.In addition to the ever-present cybersecurity threats, data security teams must consider the growing list of data compliance laws…

How data residency impacts security and compliance

3 min read - Every piece of your organization’s data is stored in a physical location. Even data stored in a cloud environment lives in a physical location on the virtual server. However, the data may not be in the location you expect, especially if your company uses multiple cloud providers. The data you are trying to protect may be stored literally across the world from where you sit right now or even in multiple locations at the same time. And if you don’t…
