What Is Threat Detection in Cybersecurity?

Threat detection and response (TDR) refers to the techniques and tools used to identify, assess, and mitigate cyber threats and vulnerabilities to digital assets. They usually include web servers, data repositories, networks, applications, and devices used by employees. Accurate threat detection is typically based on several techniques, depending on the type of hazard.

Malware

Malware is intended to harm or penetrate a computer system without the user’s permission. Some examples include adware, spyware, worms, viruses, Trojans, and more. The most effective detection techniques involve:

  • Signature-based detection means using a database of different malware signatures. A system identifies software as malicious when it aligns with a well-known threat pattern in a database. This method is effective in identifying common malware.
  • Heuristic analysis signifies thoroughly examining a program’s code to identify malware. It’s best for determining new and emerging threats.


Insider Threats

Insider threats occur when a member of an organization intentionally tries to cause harm for financial, personal, or other reasons. Insider threats are responsible for 60% of data breaches. Companies usually use different mitigation strategies.

  • User & Entity Behaviour Analytics (UEBA) is an AI-powered threat detection tool that creates employee behavioral patterns and user profiles and instantly identifies unexpected activity.
  • Remote desktop control enables companies to respond promptly to an employee’s attempt to steal data or stop phishing attacks.


Advanced Persistent Threats (APTs)

APT is a sophisticated cyber attack designed to steal data and disrupt operations, often targeting government or financial sectors. It can remain undetected for extended periods. Mitigation strategies encompass the following:

  • Utilising the latest patch systems and web application firewalls, and keeping them up to date, ensures robust protection.
  • A multi-factor authentication (MFA) system secures employee access and safeguards data.

Why AI Is Critical in Modern Threat Detection

AI-driven threat detection plays a crucial role in combating a wide range of cyber threats. According to IBM, companies that used automation and artificial intelligence (AI) to avoid security breaches saved an average of USD 2.22 million more than those that did not. AI cyber threat detection effectively addresses various cybersecurity threats and offers unique capabilities. These powerful features increase the demand for AI professionals, boosting the average AI engineers salary.

  • AI-driven threat detection and response systems continue to improve. Their detection protocols can effectively identify and respond to any threat.
  • AI and machine learning threat detection can address issues in real-time. They can also analyze vast data sets, preventing all threats from going unnoticed.
  • Intelligent threat detection analyzes trends and patterns with predictive analytics. This allows you to detect threats in advance.
  • The technology’s high accuracy eliminates irrelevant threat assessments.

Key AI Technologies Used in Threat Detection

 

Predicting potential breaches, creating security tests, and continually monitoring network traffic are the primary applications of AI in cybersecurity. Let’s briefly overview the most common technologies and their role in threat detection and prevention.

Machine Learning (ML)

Many companies use machine learning to detect cyberattacks. The applications of this technology include behavioral analysis, predictive analytics, anomaly detection, and signature-based detection.

Natural Language Processing (NLP)

NLP algorithms understand and interpret human language. Therefore, they can scan text messages and emails to distinguish phishing attempts.

Artificial Neural Networks (ANNs)

These networks excel at detecting abnormalities and perfectly identify patterns (e.g., user behavior or network activity) within large datasets.

Deep Learning

Deep learning algorithms process complex patterns (e.g., traffic data or visual content) in extensive datasets to identify malware activity and phishing attempts.

Reinforcement Learning

Reinforcement learning refers to autonomous agents making critical decisions without direct human user guidance. This AI threat intelligence can be used to determine the most effective scenario for handling cyber attacks.

How AI Enhances Threat Detection Capabilities

AI in threat detection improves accuracy by up to 95% compared to conventional techniques. Here are the ways AI is transforming cybersecurity.

Detecting Unknown (Zero-Day) Threats

AI-driven threat detection has proven highly effective in addressing zero-day vulnerabilities that have not yet been discovered by their developers or anyone who could fix them. Machine learning threat hunting uses various strategies to detect these threats, including but not limited to:

  • Behavioural analytics analyses user behaviour, such as accessing sensitive data from an unusual server.
  • Anomaly threat detection identifies any changes in network traffic.

Reducing False Positives

A false positive is an alert that warns about threats that aren’t real. Therefore, it may require businesses to allocate a significant amount of time and resources. AI helps reduce false positives by making threat detection more precise and accurate. Various algorithms thoroughly study activity patterns and compare data from many sources. It helps distinguish between regular activity and real dangers. As a result, teams can focus on the issues that truly matter.

Increasing Response Time

AI supports automated threat detection. It continuously monitors various systems, checks vast amounts of data, and takes real-time action, such as blocking access instantly. This leads to faster responses and reduces the damage caused by threats.

Improving Incident Investigation

This advanced threat detection technology thoroughly assesses the severity of each incident and prioritises them accordingly. It also gives valuable insights, which help teams be more productive and save time and resources on investigations.

Challenges and Limitations

While AI-enabled security management has proven to be highly effective, as it improves the prediction of new attacks by 66% and boosts hidden threats detection by 80%, it’s not a silver bullet.

Bias in AI Models

AI systems learn from various data. AI can replicate any biases and unintentionally engage in discriminatory practices if training data sets contain any biases.

Solution: AI training data must be continuously monitored and updated to reduce bias. Additionally, there should be transparent algorithms and a diverse range of datasets.

Data Privacy and Security Concerns

AI systems examine enormous volumes of data that frequently contain personal information.

Solution: Implementing strong encryption and data anonymisation strategies is vital, as well as ensuring that AI algorithms follow GDPR and CCPA standards.

Data Poisoning

Attackers attempt to influence the model's behaviour by adding deceptive data to datasets that train AI systems. This typically leads to inaccurate predictions and the overlooking of real threats. 

Solution: In this case, validating data origin and tracking anomalies is essential. This guarantees data accuracy and integrity.

Best Practices for Implementing AI-Powered Threat Detection

It is anticipated that third-party suppliers will account for over 90% of AI capabilities in cybersecurity. It will facilitate businesses’ adoption of innovative solutions.

Ensure High-Quality, Diverse Data Inputs

Ensure that the data sets are diverse and of high quality. This will eliminate potential bias and ensure that machine learning threat intelligence effectively identifies and resolves familiar and emerging threats.
