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.
