- Security. Analytics. Insight.5 Why Visualization? the stats ... http://en.wikipedia.org/wiki/Anscombe%27s_quartet the data...
- Security. Analytics. Insight.6 Why Visualization? http://en.wikipedia.org/wiki/Anscombe%27s_quartet Human analyst: • patterndetection • remembers context • fantasticintuition • canpredict
- Security. Analytics. Insight.7 Visualization To … Present / Communicate Discover / Explore
- Design Principles
- Security. Analytics. Insight.9 Choosing Visualizations Objective AudienceData
- Security. Analytics. Insight.10 • Objective: Find attackers in the network moving laterally • Defines data needed (netflow, sflow, …) • maybe restrict to a network segment • Audience: security analyst, risk team, … • Informs how to visualize / present data For Example - Lateral Movement Recon Weaponize Deliver Exploit Install C2 Act
- Security. Analytics. Insight.11 • Show comparisons, contrasts, differences • Show causality, mechanism, explanation, systematic structure. • Show multivariate data; that is, show more than 1 or 2 variables. by Edward Tufte Principals of Analytic Design
- Security. Analytics. Insight.12 Show Context 42
- Security. Analytics. Insight. 42 is just a number and means nothing without context 13 Show Context
- Security. Analytics. Insight.15 Use Numbers To Highlight Most Important Parts of Data Numbers Summaries
- Security. Analytics. Insight.16 Additional information about objects, such as: • machine • roles • criticality • location • owner • … • user • roles • office location • … Add Context source destination machine and user context machine role user role
- Security. Analytics. Insight.17 Traffic Flow Analysis With Context
- Security. Analytics. Insight.18 http://www.scifiinterfaces.com/ • Black background • Blue or green colors • Glow Aesthetics Matter
- Security. Analytics. Insight.19 B O R I N G
- Security. Analytics. Insight.20 Sexier
- Security. Analytics. Insight.21 • Audience, audience, audience! • Comprehensive Information (enough context) • Highlight important data • Use graphics when appropriate • Good choice of graphics and design • Aesthetically pleasing • Enough information to decide if action is necessary • No scrolling • Real-time vs. batch? (Refresh-rates) • Clear organization Dashboard Design Principles
- 22 SOC Dashboards
- Security. Analytics. Insight.23 Mostly Blank
- Security. Analytics. Insight.24 • Disappears too quickly • Analysts focus is on their own screens • SOC dashboard just distracts • Detailed information not legible • Put the detailed dashboards on the analysts screens! Dashboards For Discovery
- Security. Analytics. Insight.25 • Provide analyst with context • “What else is going on in the environment right now?” • Bring Into Focus • Turn something benign into something interesting • Disprove • Turn something interesting into something benign Use SOC Dashboard For Context Environment informs detection policies
- Security. Analytics. Insight.26 Show Comparisons Current Measure week prior
- Security. Analytics. Insight.27 • News feed summary (FS ISAC feeds, mailinglists, threat feeds) • Monitoring twitter or IRC for certain activity / keywords • Volumes or metrics (e.g., #firewall blocks, #IDS alerts, #failed transactions) • Top N metrics: • Top 10 suspicious users • Top 10 servers connecting outbound What To Put on Screens Provide context to individual security alerts http://raffy.ch/blog/2015/01/15/dashboards-in-the-security-opartions-center-soc/

- Security. Analytics. Insight.30 Information Visualization Mantra Overview Zoom / Filter Details on Demand Principle by Ben Shneiderman • summary / aggregation • data mining • signal detection (IDS, behavioral, etc.)
- Security. Analytics. Insight.31 • Access to data • Parsed data and data context • Data architecture for central data access and fast queries • Application of data mining (how?, what?, scalable, …) • Visualization tools that support • Complex visual types (||-coordinates, treemaps, heat maps, link graphs) • Linked views • Data mining (clustering, …) • Collaboration, information sharing • Visual analytics workflow Visualization Challenges
- Big Data Lake
- Security. Analytics. Insight.33 • One central location to store all cyber security data • “Data collected only once and third party software leveraging it” • Scalability and interoperability • More than deploying an off the shelf product from a vendor • Data use influences both data formats and technologies to store the data • search, analytics, relationships, and distributed processing • correlation, and statistical summarization • What to do with Context? Enrich or join? • Hard problems: • Parsing: can you re-parse? Common naming scheme! • Data store capabilities (search, analytics, distributed processing, etc.) • Access to data: SQL (even in Hadoop context), how can products access the data? The Big Data Lake
- Security. Analytics. Insight.34 Federated Data Access SIEM dispatcher SIEM connector SIEM console Prod A AD / LDAP HR … IDS FW Prod B DBs Data Lake Caveats: • Dispatcher? • Standard access to dispatcher / products enabled • Data lake technology? SNMP
- Security. Analytics. Insight.35 Multiple Data Stores raw logs key-value structured real-time processing (un)-structured data context SQL s t o r a g e stats index queue distributed processing a c c e s s graph Caveat: • Need multiple types of data stores
- Security. Analytics. Insight.36 Technologies (Example) raw logs key-value (Cassandra) columnar (parquet) real-time processing (Spark) (un)-structured data context SQL (Impala, SparkSQL) H D F S aggregates index (ES) queue (Kafka) distributed processing (Spark) a c c e s s graph (GraphX) Caveat: • No out of the box solution available
- Security. Analytics. Insight.37 SIEM Integration - Log Management First SIEM columnar or search engine or log management processing SIEM connector raw logs SIEM console SQL or search interface processing filtering H D F S e.g., PIG parsing
- Security. Analytics. Insight.38 Simple SIEM Integration raw, csv, json flume log data SQL (Impala, with SerDe) H D F S SIEM connector SIEM Requirement: • SIEM connector to forward text- based data to Flume. SQL interface Tableau, etc. SIEM console
- Security. Analytics. Insight.39 SIEM Integration - Advanced SIEM columnar (parquet) processing syslog data SQL (Impala, SparkSQL) H D F S index (ES) queue (Kafka) a c c e s s other data sources SIEM connector raw logs SIEM console SQL and search interface Tableau, Kibana, etc. requires parsing and formatting in a SIEM readable format (e.g., CEF)
