5. AI-Driven Threat Hunting: Predictive cybersecurity with AI helps analysts detect subtle indicators of compromise (IOCs) early, preventing potential security incidents.
How Artificial Intelligence Detects Threats in Cybersecurity?
- Anomaly Detection: AI models learn what normal behaviour looks like for a user or system to identify deviations from that behaviour that indicate threats. Examples of deviations may include uncommon times of logins, uncommon data access behaviour, or unusual network traffic.
- Pattern Recognition or Signature Matching: AI can identify known threat patterns (e.g., malware code signatures, threatening language, phishing language, etc.) and can often be compared to the user’s work with new patterns for the ability to detect someone interested in dealing with them promptly.
- Behavioural Analysis: AI tools can constantly watch user and system activity and notice small changes in behaviour to detect possible threats from insiders or security breaches.
- Natural Language Processing (NLP): Threat intelligence sources, like emails, chat logs, forums, etc., can be analysed by AI to detect social engineering attempts, such as identifying emerging threat language.
- Real-Time Correlation of Events: AI can quickly analyse and correlate logs and alerts from multiple security systems (e.g., firewall logs, endpoint security, cloud services, etc.) to identify complex and multi-stage attacks.
- Predictive Analytics: AI models can be trained using past attack data and known threats to predict potential attack methods or vulnerabilities that may be targeted next. This type of threat prediction enables proactive defence.
Benefits of AI-Driven Cybersecurity Solutions
- Real-Time Threat Detection: AI can detect threats as they are happening, reducing the damage by shortening the time between detection and response.

Real-World Scenarios of Artificial Intelligence in Cybersecurity
Let’s see some of the use cases of Artificial Intelligence in Cybersecurity:
Case 1: AI-Based Insider Threat Detection in the Financial Sector
A bank employs AI technology to watch its employees’ behaviour to detect negative behaviour regarding insider threats. Their system would flag an employee as a concern if the employee downloads and requests audit records with customer data at 12:00 p.m.
Ethical / Legal Considerations:
- Privacy: Employee monitoring behaviour raises an ethical issue if the employee doesn’t realise their conduct is being monitored.
- Accountability: An employee’s livelihood could be harmed if AI wrongly identifies them as involved in questionable behaviour, leading to false accusations.
Case 2: Authentication & Access Control in Government Facilities via Facial Recognition
A facility using AI facial recognition for access control may deny a valid employee entry to the government data centre because the AI model considers the recognition accuracy to be low.
Ethical / Legal Considerations:
- Bias: The technology can be biased because facial recognition may work better for some demographic groups than others, leading to unfair or discriminatory results.
- Legal Concerns: This could be a breach of local legislation regarding the protection of biometric data (i.e., the Illinois Biometric Information Privacy Act (BIPA) or the General Data Protection Regulation (GDPR) in Europe).
A cybersecurity company leverages AI technology to aggregate and analyse customer threat data across a range of countries. The idea behind the data aggregation activity is to provide predictive alerts to customers about potential threats.
Ethical / Legal Considerations:
- Cross-Border Compliance: Aggregation may violate the data protection laws of each country, e.g., GDPR for EU users.
- Consent and Transparency: None of the customers will likely have any knowledge of how or what aggregation has happened with their data, and how the AI elements are using and sharing their data.
Future of Artificial Intelligence in Cybersecurity
