NBAD technology/techniques are applied in a number of network and security monitoring domains including: (i) Log analysis (ii) Packet inspection systems (iii) Flow monitoring systems and (iv) Route analytics. NBAD has also been described as outlier detection, novelty detection, deviation detection and exception mining. [2]
Several algorithms exist to help with analysis of data – Dijkstra's algorithm, breadth-first search, and depth-first search. Link analysis focuses on analysis of relationships among nodes through visualization methods (network charts, association matrix). Here is an example of the relationships that may be mapped for crime investigations: [3]
Once the threat model is completed, security subject matter experts develop a detailed analysis of the identified threats. Finally, appropriate security controls can be enumerated. This methodology is intended to provide an attacker-centric view of the application and infrastructure from which defenders can develop an asset-centric mitigation ...
Traffic analysis method can be used to break the anonymity of anonymous networks, e.g., TORs. [1] There are two methods of traffic-analysis attack, passive and active. In passive traffic-analysis method, the attacker extracts features from the traffic of a specific flow on one side of the network and looks for those features on the other side of the network.
The Cyber Security and Information Systems Information Analysis Center (CSIAC) is a U.S. Department of Defense Information Analysis Center (IAC) sponsored by the Defense Technical Information Center (DTIC), and Assistant Secretary of Defense for Research and Engineering (ASDR&E). CSIAC is hosted by Quanterion Solutions Incorporated.
User behavior analytics (UBA) or user and entity behavior analytics (UEBA), [1] is the concept of analyzing the behavior of users, subjects, visitors, etc. for a specific purpose. [2] It allows cybersecurity tools to build a profile of each individual's normal activity, by looking at patterns of human behavior , and then highlighting deviations ...
For example, a signals intelligence collection platform will record all the electromagnetic signals it received from an antenna pointed to a particular target at a particular time. Assuming the target was radar, the ELINT analysts would be focused on the purpose and coverage of the radar.
The main steps in forensic analytics are data collection, data preparation, data analysis, and reporting. For example, forensic analytics may be used to review an employee's purchasing card activity to assess whether any of the purchases were diverted or divertible for personal use.
