DEFENSE AGAINST CYBER ATTACK:

Role of a Human (Cyber Analyst)

• Detect intrusion

• Recommend solution

• Threat insight

• Gather evidence

• Prevent intrusion

• Find vulnerability in the system

• Block suspected traffic

• Forensic analysis:

• Create rules to detect future attack

• Nature of attack

Multivariate:

Packet Capture/TCP dump, (ip, port, pkt size, time, etc.

multiple features) from network sensors.

Firewalls

SECURITY DATA:DATA CAPTURED THROUGH SENSORS

Relational:

Flow data through Network: can be collected from routers:

connection between IPs, hosts.


Temporal:

Log Files/Activity/Events: Host/endpoint events over time


• Communicate findings

• Overview

• Analyze:

• Compare and Relate

• Find trend/ pattern

• Predict

• Find anomaly

WHY VISUALIZATION

VISUAL ANALYTICS:

INTERACTIVE VISUAL INTERFACE

FOR DECISION MAKING

Visual Information Seeking “Mantra”-Ben Shneiderman

• Overview data using charts, dashboard, tables: see

all relevant data

• Find pattern, trend, outlier, correlation

• Sort by rank

• Group similar features

• Zoom and filter: select only interesting ones

• Details on Demand: details of the selected alert

MODES OF OPERATIONS

Put it all together in analysts workflow:

• Contextual views

• Dashboard for overview

• Visual analytics with multiple coordinated views

• Situational awareness for immediate assessment

DASHBOARDS

Example: SPLUNK

MULTIPLE COORDINATED

VISUALIZATIONS

TempoViz

Low priority

High priority

Mid priority

Alerts aggregated over time

SITUATIONAL AWARENESS

Situation awareness is the ability to :

•assess data

•evaluate options

•make decisions in a timely manner.

• Allow humans and machines to work together.

• Bridge the gap btwn security experts & dataviz experts.

• Provide contextual clues to the analysts.

• Integrate visual analytics in analyst workflow.

• Make room for scalability and efficiency.

• Avoid visual representations requiring lot of explanation.

• Choose the network layout that avoids edge crossing or

node overlapping.

• Aggregation of data should be obvious.
