Introduction to AI and Security

AI has applications that require human intelligence like decision-making and pattern recognition.

What is AI?

Systems that perform tasks requiring human intelligence.
Examples include decision-making and pattern recognition.

Categories of AI:

Narrow AI: Performs specific tasks, such as spam filtering.
General AI: Hypothetical AI with human-level intelligence.

What is Machine Learning (ML)?

A subset of AI that trains systems to learn from data without explicit programming.

Machine Learning

Supervised Learning: Models are trained on labeled data, e.g., malware detection.
Unsupervised Learning: Models identify patterns without labels, e.g., anomaly detection.
Reinforcement Learning: Systems learn by interacting with their environment and receiving feedback, e.g., AI in autonomous cybersecurity systems.

AI Enabling Security

AI systems support security.
Can detect anomalies, predict potential attacks, and secure systems against known and unknown threats.
Examples include AI in intrusion detection systems and AI-driven malware analysis.

Security Enabling Better AI

Homomorphic Encryption allows computations on encrypted data without decrypting it, ensuring privacy in AI models handling sensitive data.
Federated Learning trains AI models across multiple devices or servers while keeping data decentralized, enhancing privacy by avoiding direct access to the data itself.

Why AI Security is Important

AI is embedded in various sectors, from smart cities to healthcare.
As AI takes over decision-making, attackers are more incentivized to target these systems due to the potential damage.
AI is crucial for understanding and preparing for the evolving security landscape.

Role of AI in Cybersecurity

Defense: Detects and prevents cyber threats through pattern recognition and real-time analysis.
Offense: Used by attackers to automate attacks and create sophisticated malware.

Why AI is Critical in Modern Cybersecurity

Automation provides efficiency and speed.
Adaptive defense allows the system to learn and evolve.

AI Applications in Cybersecurity

Intrusion Detection Systems (IDS) use anomaly detection.
Malware detection utilizes machine learning models.
Behavioral Analysis detects insider threats.

Challenges of AI in Security

AI is a vulnerability.
Examples include Adversarial Machine Learning (AML), where attackers can craft inputs to cause AI systems to make mistakes.

AI Vulnerabilities

Data Poisoning involves manipulating training data to degrade performance.
Adversarial Attacks introduce perturbations to fool AI models.
Model Inversion Attacks extract sensitive data from AI models.

Trust and Bias Issues

AI Bias can influence results.
Lack of Transparency hinders trust in AI systems.

The Dual Use of AI

Offensive AI: Attackers leverage AI for smart malware, spear-phishing and creating deepfakes for fraud.
Defensive AI: AI predicts, detects and responds to security threats before harm occurs.

The importance of AI in Modern Cybersecurity

Scalability and efficiency are crucial for managing large datasets and rapidly detecting threats.
The evolution of cyber threats necessitates AI to adapt and evolve alongside them.
