They adjust their responses based on attacker interactions, creating confusing signals that allow for observation and learning from cyberattacks without triggering alarms.

2. Deepfake and Synthetic Media Detection
Artificial intelligence models of manipulated media (images, audio, video) can be used against targets in social engineering or misinformation attacks. 

3. Security Log Analysis at Scale
Artificial intelligence can process tonnes of logs originating from all systems in the environment, and be aware of patterns and correlations from all platforms, which is manually impossible.

4. Dynamic Access Control
Artificial intelligence can determine access privileges in real time by analysing context such as user behaviour, location, and device health. This approach replaces static rules with dynamic, situation-aware decisions.

5. AI-Driven Threat Hunting
Artificial intelligence helps human analysts by detecting subtle indicators of compromise (IOCs) across various systems. It can also uncover hidden threats early, before they grow into major security incidents.

How Artificial Intelligence Detects Threats in Cybersecurity?

1. 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.
2. Pattern Recognition or Signature Matching: AI has the ability to 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.
3. 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.
4. 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.
5. 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.
6. 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

1. Real-Time Threat Detection: AI can detect threats as they are happening, reducing the damage by shortening the time between detection and response.
2. Reduced False Positive: Traditional systems alert on changes in data, while AI learns from both data and context. Precision of alerts increases, hence there is less unnecessary alerting.
3. Scalability Across Large Networks: AI easily monitors and analyses huge, complex networks and doesn’t experience performance degradation.
4. Automated Incident Response: AI systems can automatically take predetermined action, such as isolating an infected device or blocking a malicious IP address. Time savings can be significant here.
5. Predictive Risk Analysis: AI can identify access points for threats or open vulnerabilities by analysing historical data and trends, allowing users to take preventive measures.
6. Improved Threat Intelligence: AI can quickly gather and analyse global threat data, offering useful insights that enhance human-generated intelligence to support better decision-making.
7. Adaptability to Evolving Threats: Machine learning gives infinite updates to AI-based systems for a wide breadth of evolving attack types without manual reprogramming of systems.
8. Enhanced User and Entity Behaviour Analytics (UEBA): AI monitors long-term account activity to identify users with unusual behaviour that may indicate insider threats.

Traditional vs AI-Powered Cybersecurity Approaches

Challenges and Considerations of Artificial Intelligence in Cybersecurity

1. Limited Data Availability: AI needs to be trained on large data sets of high quality, which can be hard to come by for cybersecurity. 

2. Privacy Concerns: AI models that monitor user behaviour can often go against user expectations and may violate privacy laws, creating potential legal and ethical issues.

4. Model Bias: If the training data is imprecise or biased, the AI models may generate false positives or miss threats. 

3. Adversarial Attacks: Attackers can manipulate AI model outputs to misclassify threats or ignore them completely. 

5. Lack of Explainability: The reasoning behind many AI model decisions is opaque, thus, there is less trust and understanding from the analyst. 

6. High Costs: Creating and maintaining AI models takes a substantial amount of resources and skilled manpower. 

7. Integration Challenges: A New AI tool may not integrate well with legacy or existing cybersecurity tools. 

8. Over-Reliance on AI: Excessive dependence on AI will mean that there is reduced human oversight, which increases risk. 

9. Legal Uncertainty: When AI systems misclassify or fail, it is not clear who is ultimately liable. 

10. Ethical Risks: Surveillance and profiling led by AI can produce legitimate ethical and fairness challenges.

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: 

1. Privacy: Employee monitoring behaviour raises an ethical issue if the employee doesn’t realise their conduct is being monitored. 
2. 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: 

1. Bias: The technology can be biased because facial recognition may work better for some demographic groups than others, leading to unfair or discriminatory results.
2. 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).

Case 3: AI-Based Threat Intelligence Platform with Global Data Sharing

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:

1. Cross-Border Compliance: Aggregation may violate the data protection laws of each country, e.g., GDPR for EU users. 
2. 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

1. Predicting Threats Ahead of Time: AI will be developed to predict attacks before they even occur, by using real-time data collection with learning behaviours.

2. Self-Healing Actions: An AI-based system could automatically detect and respond to an attack by monitoring its environment, detecting the attack, and fully recovering without any intervention from humans at all.

3. Integration with previous SOC Concepts: AI will integrate into the previous version of SOC in a way to better consume AI and provide improved decision-making.

4. Real-Time Adaptive Defence: An AI-enabled cyber tool would allow cybersecurity systems to adapt their defence, based on threats as they occur.

5. Collaboration between AI-Agents: AI agents could collaborate across networks, organisations, and services to aggregate shared threat intelligence.

6. Explainable AI, or XAI: There will be a greater emphasis on AI having a reason for its decision-making to foster trust, explanation, and accountability.

7. AI vs. AI Battles: The cyber world will become so overrun by AI that cybersecurity will need AI to protect against AI attacks, resulting in a new arms race in cyberspace.

8. Stronger Legal Frameworks: Legal and ethical frameworks for using Artificial Intelligence in cybersecurity will continue to develop, aiming to support responsible and effective AI deployment. These evolving guidelines help ensure AI is used in ways that are both safe and ethical.

9. Hyperautomation for Security: AI will integrate the security task automation, eliminating many human workloads while reducing our time to respond.

Ambitious User Behaviour Analytics: AI will improve the detection of insider threats by using advanced behavioural models that can recognise patterns of behaviour linked to likely malicious intent.
