A NoSQL database provides a mechanism for data storage and retrieval, without using the tabular relations associated with relational databases. Originally referred to as "non-SQL" or "non-relational" databases, NoSQL databases are increasingly used in big data and real-time web application environments. NoSQL systems are also sometimes called “Not only SQL” to emphasize that they may support SQL-like query languages or sit alongside SQL databases in polyglot-persistent architectures.

To ascertain risk, national security and intelligence professionals have long used concepts such as known knowns, known unknowns, and unknown unknowns. The idea of unknown unknowns was created in 1955 by American psychologists Joseph Luft (1916–2014) and Harrington Ingham (1916–1995). This concept continues to be used today in risk assessments and is applicable to technology. The unknown unknowns are the threats and potential problems that remain invisible until their impact manifests.

What do big mountain ascents and modern network operations have in common? You’ll only succeed when you’re learning from experience. This was one among many compelling takeaways that attendees took from our recent NetOps Summit. Centered on the theme “visibility anywhere,” this event featured a number of compelling presentations, including a keynote from Jimmy Chin, the professional climber, photographer, and Academy Award-winning filmmaker.

Any new technological breakthrough tends to be greeted by two opposing factions. On one hand, you have promoters, for whom this technology is a panacea, the cure for every ailment plaguing the current environment.

Having any form of application discovery can be of great benefit. With these capabilities, you can determine what is deployed within your infrastructure and better understand what monitoring to apply to each device. When you know which applications are running within your environment, you can group devices by their associated applications.
