The new Cisco security solutions integrate a range of sophisticated technologies to identify and analyze key threats through advanced behavioral analysis of real-time data. However, some of these databases support both SQL and non-SQL forms of data processing.īig data analytics can be done in combination of advanced analytics disciplines such as predictive analytics and data mining.Ĭisco acquired Cognitive Security in 2013, a company focused on applying artificial intelligence techniques to detect advanced cyber threats.

There is an industry concept called Not-Only SQL (NoSQL), which is the name given to several databases that do not require SQL to process data. The differentiation in the usefulness of any big data solution is the merging of numerous data sources and sizes that are all in the same infrastructure and providing the ability to query across all of these different data sets using the same language and tools. NetFlow is one of the largest single sources, and it can grow to tens of terabytes of data per day in large organizations, and it is expected to grow over the years to petabytes. There are numerous, disparate data sources. Industry experts estimate that the majority of the data in any organization is unstructured, and the amount of unstructured data is growing significantly. Simple Network Management Protocol (SNMP) logs.In the world of cyber security, a lot of the network can be also categorized as unstructured: Social media (Facebook, Twitter, LinkedIn) status updates.

Multimedia content such as videos, photos, and audio files.The prime examples of unstructured data are as follows: Typically, unstructured data is defined as data that is not typically tracked in a “structured” or traditional row-column database. The term unstructured data is used when referring to data that does not have a predefined data model or is not organized in a predetermined way. You can find details of the Cisco VNI global IP traffic forecast and the methodology behind it at. Cisco VNI is an ongoing initiative to forecast and analyze the growth and use of the Internet, in addition to the data being transferred. For instance:Ĭisco has created the Cisco Visual Networking Index (VNI). It can range from a few terabytes to yottabytes of data in a single data set. The size of data that can be classified as big data is a moving target.

Big data usually includes data sets with sizes beyond the ability of commonly used software tools to capture, curate, manage, and process the data within a tolerable elapsed time.An accumulation of data that is too large and complex for processing by traditional database management tools.A formal definition for big data can be obtained in the Merriam-Webster dictionary. Let’s cut through the marketing hype and get down to the basics of the subject. It seems that a lot of people have different views of what big data is. There are a lot of very interesting definitions for the phenomenon called big data. NetFlow plays an important role for big data analytics for cyber security, and you will learn why as you read through in this chapter. These data sets can include different types of structured and unstructured data processed in a “streaming” fashion or in batches. Many in the industry are changing the tone of their conversation, saying that it is no longer if or when your network will be compromised, but the assumption is that your network has already been hacked or compromised, and suggest focusing on minimizing the damage and increasing visibility to aid in identification of the next hack or compromise.Īdvanced analytics can be run against very large diverse data sets to find indicators of compromise (IOCs). Big data analytics can play a crucial role in cyber security.

Introduction to Big Data Analytics for Cyber Securityīig data analytics is the practice of studying large amounts of data of a variety of types and a variety of courses to learn interesting patterns, unknown facts, and other useful information.
