Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon many factors, including considerations such as the amount of multiprogramming in the user s job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results similar to those stated here. 2

3 Big Data Facts Big data analytics is delivering value today 90% dei dati sono stati creati negli ultimi due anni 1 Big data analytics has the potential to reduce cyber security risk and increase agility Big data analytics is challenging, but manageable expected to grow from US$3.2 billion in 2010 to US$16.9 billion in Existing big data analytics capabilities can be leveraged to improve information security Es. le istituzioni finanziarie utilizzano già sofisticati sistemi di analisi per antifrode ed antiriciclaggio. Le compagnie aeree svolgono una costante analisi dei comportamenti dei loro utenti, per proporre offerte ad-hoc 1 public.dhe.ibm.com/common/ssi/ecm/en/pos03099usen/pos03099usen.pdf 2 3

4 Innovative technology changes everything 1 trillion connected objects 1 billion mobile workers Social business Bring your own IT Cloud and virtualization 4

5 Attacker motivations are rapidly escalating National Security Nation-state actors Stuxnet Espionage, Activism Sponsored groups and Hacktivists Aurora Monetary Gain Revenge, Curiosity Insiders and Script-kiddies Code Red Organized crime Zeus 5

6 Organized groups are using multiple techniques Using social networking and social engineering to perform reconnaissance on spear-phishing targets, leading to compromised hosts and accounts Infiltrating a trusted partner and then loading malware onto the target s network Creating designer malware tailored to only infect the target organization, preventing positive identification by security vendors Exploiting zero-day vulnerabilities to gain access to data, applications, systems, and endpoints Communicating over accepted channels such as port 80 to exfiltrate data from the organization 6

7 Security Intelligence is enabling progress to optimized security Security Security Intelligence: Information and event management Advanced correlation and deep analytics External threat research Intelligence Optimized Role based analytics Identity governance Privileged user controls Data flow analytics Data governance Secure app engineering processes Fraud detection Advanced network monitoring Forensics / data mining Security rich systems Proficient User provisioning Access management Strong authentication Database activity monitoring Access monitoring Data loss prevention Application firewall Source code scanning Virtualization security Asset management Endpoint / network security management Basic Centralized directory Encryption Access control Application scanning Perimeter security Anti-virus People Data Applications Infrastructure 7 JK

8 What I can get from BigData to better protect my enterprise Examples of information security using BigData and Security Analytics Monitoring security incidents and events Producing cyber intelligence Addressing Phishing Keeping systems available Discovering a breach Identifying threat trends and evolution Detecting an embedded cyber attack 8

9 How to use BigData to improve security? BigData Analysis Process Security Insight Experts Tools Methods Visualizzation 9

10 Permutations of malicious identifiers are limitless Domain dogpile.com kewww.com.cn ynnsuue.com wpoellk.com moveinent.com moptesoft.com varygas.com earexcept.com fullrow.com colonytop.com IP Address File Checksum c69d172078b439545dfff28f3d3aacc1 51e65e6c798b03452ef7ae3d03343d8f 6bb6b9ce713a00d3773cfcecef515e02 c5907f5e2b715bb66b7d4b87ba6e91e7 bf30759c3b0e482813f0d1c324698ae ec103847c69646dcbc667df42 23c4dc14d14c5d54e14ea38db2da ea6c0c4e875d777276a111543e 00b3bd8d75afd437c1939d8617edc22f 01e22cce71206cf01f9e863dcbf0fd3f 10

11 The Result Attackers are bypassing traditional security defenses 11

12 We need a new Approach Image retrieved from 12

13 A change in mindset is already happening Audit, Patch & Block Detect, Analyze & Remediate Think like a defender, defense-in-depth Think like an attacker, counter intelligence 13

14 By monitoring for subtle indicators across all fronts 1 Break-in Spoofed with malicious file attachment sent to users 2 Command & Control (CnC) Latch-on Anomalous system behavior and network communications 3 Expand Device contacting internal hosts in strange patterns 4 Gather Abnormal user behavior and data access patterns 5 Command & Control (CnC) Exfiltrate Movement of data in chunks or streams to unknown hosts 14

15 Traditional Security Operations and Technology Big Data Analytics Logs Events Alerts Configuration information System audit trails Network flows and anomalies External threat intelligence feeds Web page text and social activity Identity context Full packet and DNS captures Business process data Customer transactions Building New Insights New Insights requires collecting and analyzing data from security infrastructure and beyond 15

16 Brings New Considerations Storage and Processing Collection and integration Size and speed Enrichment and correlation Analytics and Workflow Visualization Unstructured analysis Learning and prediction Customization Sharing and export 16

17 Security has become a Big Data problem 17

18 Complementary analytics and workflow from IBM Security Intelligence Platform Big Data Platform Real-time Processing Real-time data correlation Anomaly detection Event and flow normalization Security context & enrichment Distributed architecture Security Operations Pre-defined rules and reports Offense scoring & prioritization Activity and event graphing Compliance reporting Workflow management IBM Security Intelligence with Big Data Big Data Warehouse Long-term, multi-pb storage Unstructured and structured Distributed infrastructure Preservation of raw data Hadoop-based backend Analytics and Forensics Advanced visuals and interaction Predictive & decision modeling Ad hoc queries Spreadsheet UI for analysts Collaborative sharing tools Pluggable UI 18

19 QRadar leverages Big Data to identify security threats New appliances with massive scale Payload indexing leveraging a purpose-built data store Google-like search of large data sets Intelligent data policy management Advanced threat visualization and impact analysis Enrichment with X-Force and external intelligence 19

20 Example QRadar uses cases Behavior monitoring and flow analytics Network Traffic Doesn t Lie Attackers can stop logging and erase their tracks, but can t cut off the network (flow data) Activity and data access monitoring Improved Breach Detection 360-degree visibility helps distinguish true breaches from benign activity, in real-time Stealthy malware detection Irrefutable Botnet Communication Layer 7 flow data shows botnet command and control instructions 20

21 Extending Security Intelligence with additional Big Data analytics capabilities IBM Security QRadar Data collection and enrichment Event correlation Real-time analytics Offense prioritization Security Intelligence Platform Advanced Threat Detection 1. Analyze a variety of non-traditional and unstructured datasets 2. Significantly increase the volume of data stored for forensics and historic analysis 3. Visualize and query data in new ways 4.

26 Spear-phishing phishing analysis ATTACKER TARGET User receives risky from personal social network User is redirected to a malicious website Drive-by exploit is used to install malware on target PC 26

27 Using Big Data to mine for trends within Use BigInsights to identify phishing targets and redirects Build visualizations, such as heat maps, to view top targets 27

28 Loading phishing data and corresponding redirects to QRadar 28

29 Hunting for targeted C&C domains ATTACKER Attacker registers or acquires a domain Compromised hosts phone home to attacker C&C servers Internal attacks lead to more infections Attacker changes the location of servers, but domains stay the same Hosts and servers phone home and exfiltrate data 29

30 Analyze historical DNS activity within organization 30

31 Automate correlation against DNS registries 31

32 Advanced analytics identify suspicious domains Why only a few hits across the entire organization to these domains? Correlating to public DNS registry information increases suspicions 32

33 Importing results to QRadar for real-time analysis View real-time data and look for active connections Correlate against network activity and visualize 33

34 Key Takeaways 1. Traditional defenses are insufficient 2. Security has become a Big Data problem 3. Security Intelligence is a Big Data solution 4. New analysis can lead to new insights Thank You!!! 34
