Today, cybersecurity has become more critical as the internet and digital systems integrate into every aspect of our lives. Cyberattacks pose significant risks, from individuals to large corporations. The magnitude and diversity of these threats have made traditional security methods insufficient, making artificial intelligence (AI) an essential tool for providing next-generation security solutions. AI can detect threats faster, prevent them, and automatically respond to risks.
Parameters of AI Security
AI offers significant advantages in combating attacks through various methods and tools in the cybersecurity field. AI-based security solutions span a wide range, from data analysis and behavior modeling to automatic attack detection and AI-powered firewalls.
Threat Detection with Machine Learning: Machine learning (ML), a subset of AI, analyzes large datasets to detect threat models and anomalies. Traditional security systems typically identified threats based on predefined attack types. However, as new and more complex cyberattacks emerged, it became increasingly challenging to detect previously unidentified threats. This is where machine learning comes into play. ML algorithms learn from abnormal network traffic or unusual user behavior, predicting threats from this data. To visualize this, imagine an employee logging into the network from multiple devices outside of normal working hours. This could be flagged as suspicious by machine learning, triggering a warning system. In this way, threats can be identified and mitigated before they even occur.
Anomaly Detection: This refers to identifying deviations from normal patterns in network traffic or system performance. AI can analyze these deviations and detect potential cyberattacks at an early stage. For instance, while a computer network typically operates with a certain traffic volume, a sudden spike in traffic could indicate a Distributed Denial of Service (DDoS) attack. AI identifies such anomalies and can notify system administrators instantly or take autonomous preventive measures against the attack.
Autonomous Response and Automation: Traditional security solutions may detect threats successfully, but responding to them swiftly poses another challenge. AI develops autonomous response mechanisms to neutralize threats automatically. This is a major advantage, particularly in situations where rapid response is essential, such as during a data breach. AI-powered automated security systems can respond immediately based on the current security policy once an attack is detected. For example, if suspicious activity is detected in a user account, AI can automatically suspend that user's system access or isolate the suspicious device from the network. Such automation saves time for cybersecurity professionals and helps prevent larger damages.
Advantages of AI in Fighting Cyber Threats
Continuous Learning Capability: Through machine learning, AI continuously analyzes data and learns from it. This feature allows the system to detect even more complex threats over time. As security threats become more sophisticated each day, AI updates itself to adapt to new attack methods and can detect threats at an earlier stage.
Big Data Analysis: In the world of cybersecurity, billions of data points are generated daily. It is impossible to analyze all this data using traditional methods. AI can quickly analyze large datasets, and this is an extraordinary advantage, as it can extract meaningful results from these vast amounts of data. This enables real-time detection of cyber threats.
Protection Against Zero-Day Threats: Zero-day threats exploit previously unknown vulnerabilities and are among the most dangerous attacks. Traditional security systems work based on known threat signatures, making them ineffective against zero-day attacks. AI can recognize zero-day threats by analyzing abnormal behavior and deviations in data flow. Thus, it becomes possible to detect new threats even without a known signature.
Areas Where AI Is Used in Security
Firewalls and Breach Detection: AI-powered firewalls analyze network traffic continuously, rather than following predetermined rules, to detect new threats. This provides a more flexible and effective security layer than traditional firewalls. Breach detection systems equipped with AI can quickly identify data breaches and issue real-time alerts.
Combating Social Engineering Attacks: AI can be used to detect social engineering attacks, particularly phishing attacks. AI-based systems analyze fake emails or websites, distinguishing between real and fake, and warn users. This has become one of the most critical components of cybersecurity, especially in areas where human error is the weakest link.
Authentication Systems: Traditional password-based authentication methods are becoming increasingly vulnerable to cyberattacks. AI enhances security through new-generation authentication systems like biometric verification and behavioral biometrics. For instance, AI can analyze a user’s typing style, mouse movements, or device usage habits to prevent the use of fake identities.
Challenges Facing AI-Based Security
False Positives and Negatives: One of the biggest challenges AI-based security systems face is the occurrence of false positives and false negatives. False positives can cause harmless activities to be flagged as threats, while false negatives can result in real threats being overlooked. These types of errors require constant improvements to enhance the sensitivity of security systems.
AI-Assisted Cyberattacks: Just as AI is used for cybersecurity, malicious actors have also started using AI for cyberattacks. This can lead to more sophisticated and harder-to-detect attacks in the future. AI-assisted attacks can analyze systems faster and use learning algorithms to bypass defense measures.
