Study Notes

Course Information

  • Course Title: Data analytics for Cyber Security
  • Instructor: Senait Desalegn
  • Institution: Addis Ababa Institute of Technology, Addis Ababa University
  • Date: October 2024

Course Introduction

  • The course covers using data analytics to address cybersecurity challenges.
  • It does not cover traditional security configurations or patching vulnerabilities.

What is Cybersecurity?

  • Cybersecurity is about protecting valuable electronic and physical assets from unauthorized access.
  • These assets include personal devices, network devices, information assets, and infrastructural assets.
  • Cyberattacks are the methods used to breach security and gain access to valuable assets.

Aims of Cybersecurity

  • Preventing cyberattacks against critical assets
  • Detecting cyber threats
  • Responding to threats that penetrate access to critical assets
  • Recovering and restoring systems after successful attacks

Assets Affected

  • Personal: Phones, tablets, computers, external drives, cloud drives, email accounts, fitness trackers, smart watches, smart glasses, media devices, bank accounts, credit cards, personal gaming systems
  • Public: Smart meters, power grids, sewage controls, nuclear power plants, rail lines, airplanes, traffic lights, citizen databases, websites (county, state, federal), space travel programs, satellites
  • Corporate: Customer databases, websites, business applications, business networks, emails, off-the-shelf software, intellectual property

Motivation behind Cyber Threats

  • Stealing intellectual property
  • Gaining access to customer data
  • Making a political statement
  • Performing cyber espionage
  • Damaging reputation (for fun, or impeding access to data/applications)

Why do we have security risks?

  • Applications with dependencies
  • Logical errors in software code
  • Organizational risks (multiple partners)
  • Lack of user awareness (social engineering and phishing)
  • Personality traits of individuals using the systems

Handling Cyber Attacks

  • Protecting resources and Hardening Defenses
  • Capturing data logs
  • Monitoring systems
  • Tracing attacks and Predicting risks
  • Identifying vulnerabilities

Overall Areas of Cybersecurity

  • Network Security
  • Cyberphysical Security
  • Data and Information Security
  • Application Security

Sub areas of Cybersecurity

  • Application Security: Incorporating security into software development.
  • Data and Information Security: Securing data from unauthorized access and misuse.
  • Network Security: Securing computer networks to prevent unauthorized access.

Cyber Physical Security

  • Emerging challenges due to the coupling of cyber and physical systems (e.g. power plants).
  • Risk of disrupting a cyber component, risk of unauthorized control of a cyber system, gaining unauthorized control of physical systems.

Data Analytics

  • Focuses on analyzing large amounts of data from diverse sources to find actionable information.
  • Involves techniques from data mining, statistics, and business management.
  • Key dimensions: volume, velocity, variety, veracity, venue (massive datasets generated rapidly, heterogenous, accurate in complex environments, changing by location).

Anatomy of an Attack

  • Clustering: Using methods such as IDS, logs (e.g., SNORT), keyword matrices and word frequency matrix; critical alerts.
  • Temporal Proximity: Time intervals used for analyzing patterns.
  • Network Evolution: Analyze and evaluate how networks evolve over time.

Why Data Analytics is Important

  • Helps understand human aspects of attacks.
  • Helps determine temporal, spatial, data-driven aspects of attackers' behavior.
  • Helps to understand attacks across various aspects that might use multiple parts of a framework or different databases.
  • Helps find trends/patterns/anomalies over time or in relation to location and understand why an attack may occur.

How Can Data Analytics Help?

  • Gleaning novel information from multiple sources to identify critical systems/flaws.
  • Support defenses of cyber systems
  • Analyze data to trace attacks
  • Predict risks
  • Identify vulnerabilities
  • Create robust access control rules through usage and security policies.

Focus of this Course

  • Addresses cybersecurity challenges using data analytics.
  • Aims at threat hunting/detection, prevention/mitigation, vulnerability discovery, prospective & retrospective analysis. This covers how attacks occur and how to prevent them in the future.

Conclusion

  • Course aims to use data analytics to find solutions for cybersecurity issues.
