Threat intelligence - nullmeetblr 21st June 2015
- 2. Threat Intelligence (informally) Information about “bad stuff” (threats) Actors, Vulnerabilities, Exploits, Malware/Tools, etc. (“TTPs” & “IOCs”)
- 3. Why Intelligence? You don’t know what you don’t know You can’t act on what you don’t know I’m sure they are Sun Tzu references
- 4. A Sample feed of Phishing Indicator
- 5. Can you guess how much a TI data feed cost?
- 6. Symantec DeepSight security risk feed is approximately $27,500 per year Symantec's 12-month retail subscription to its reputation feed costs $95,300 FireEye Threat Intelligence 20% of the cost of the purchased appliance starting around $17,400 and increasing to more than $175,000 per unit. LogRhythm, which does not offer data feed subscriptions, starts at about $28,000 per year
- 8. 1. How many sources does the threat intelligence service pull from? 2. How frequently is the threat intelligence updated? 3. How are the threats evaluated? 4. How is the data formatted? 5. Can the threat data be correlated with information that the enterprise already has about its security posture? Five Questions To Ask When Choosing A Threat Intelligence Service
- 9. CRITs - Collaborative Research Into Threats
- 10. CRITs is a web-based tool which combines an analytic engine with a cyber threat database that not only serves as a repository for attack data and malware, but also provides analysts with a powerful platform for conducting malware analyses, correlating malware, and for targeting data.
- 11. Advantage of CRIT’s Static analysis Dynamic analysis Services Supports STIX and TAXII etc…
- 12. What value we add.? Automation of tasks Correlating past data

- 1. How many sources does the threat intelligence service pull from? Some services are a single feed from a specific vendor's research arm, or even a white-labeled feed from another company. Other threat intelligence services collect and correlate data from dozens of different sources, giving a more comprehensive view of the threats. "That's not to say that all the data has to be confirmed by multiple sources," James notes. "Sometimes a single anomaly from a single source is your first indication of a zero-day attack." 2. How frequently is the threat intelligence updated? Different threat intelligence services approach their reporting with different philosophies. Some send out data constantly, offering just the basics on what they are seeing. Others take time to analyze the data and correlate it before they publish it. Timing may be important to some providers and not to others. 3. How are the threats evaluated? Some threat intelligence services simply send out the data they collect, without ranking or evaluating it. Others offer a simple ranking, similar to the "critical" and "important" rankings used to measure new vulnerabilities. In some cases, the threats may be given a specific score, using a system that ranks criteria such as potential damage and likelihood of infection. Some services correlate this data from many different sources and come up with an overall ranking. 4. How is the data formatted? Particularly in cases where the threat intelligence comes from multiple sources, it can be extremely difficult to interpret and manage. Different sources have different ways of measuring and interpreting threat data, and getting a feed from all of those sources can result in a jumble of information that isn't much more helpful than no data at all. A useful threat intelligence service will provide a way to normalize the threat information and present it in a way that can be reported consistently over a particular time period and plugged into reports that the enterprise already does. 5. Can the threat data be correlated with information that the enterprise already has about its security posture? One of the great promises of threat intelligence is that it might be tailored so that it doesn't just give general threat information, but also provides insight as to whether a particular threat might affect a specific organization. Correlating threat data with information about the current state of the enterprise defenses allows an organization to come up with a real assessment of risk. In many cases, however, the threat data you receive from an intelligence service does not reflect the specific systems your organization has, or the specific data it's trying to protect. A sophisticated attack against Unix devices might be ranked highly on the threat meter, but it may be moot if your enterprise is an all-Windows shop. Over time, many threat intelligence services are tying into security information and event management (SIEM) systems that collect and correlate enterprise security posture data. The combination of current threat data and up-to-the-minute security posture information may eventually make it easier for enterprises to make defensive decisions that fit their specific situation, and to more accurately assess the risks they face from a particular threat.
