With the rapid advancement of the digital environment, cyber security threats are becoming increasingly sophisticated. Various security threats such as ransomware attacks, phishing scams, and data breaches are on the rise, and traditional security systems alone are struggling to effectively block these attacks. As a result, AI (Artificial Intelligence)-based security solutions are gaining attention, and AI technologies based on machine learning and deep learning are playing a powerful role in detecting and responding to cyber threats.
This article examines the most threatening cyber security threats and the AI-based security solutions that counter them, and suggests ways for businesses and individuals to improve their security levels.
1. Latest Cyber Security Threats Defended by AI
Today's biggest security threats are hacking techniques utilizing AI and automated cyberattacks. In particular, with the advancement of AI-based attack technologies, threats that existing security systems cannot detect are increasing.
1) Increasing Ransomware Attacks
Ransomware is malicious code that encrypts a user's data and demands money in exchange for decryption. Recently, hackers have been using AI to make ransomware attacks more sophisticated.
AI Security Solution Response:
• AI-based real-time behavior analysis: AI analyzes user file access patterns and blocks abnormal data encryption attempts in real time.
• Automatic threat isolation function: If AI detects suspicious ransomware activity, it immediately isolates the device from the network.
<Case Study>
Microsoft Defender uses AI-based machine learning models to learn ransomware attack patterns and proactively block attack attempts.
➡ Additional Case Study: In 2023, a US medical institution saw a 70% reduction in ransomware infections after implementing an AI-based security solution.
2) Phishing Attacks and Social Engineering
Phishing attacks are methods of stealing personal or financial information by deceiving users, typically through emails, text messages, and social media messages. Recently, with AI being used in phishing attacks, more sophisticated and realistic fraudulent emails are being created.
AI Security Solution Response:
• AI-based email filtering: AI analyzes email content and automatically blocks messages with a high probability of being phishing attempts.
• Voice and video AI analysis: AI detects fake voices and deepfake videos to prevent phishing attacks.
<Case Study>
Google's Gmail AI filter detects and automatically blocks 99.9% of phishing emails.
➡ Additional Tip: AI learns user behavior patterns to regularly update phishing defense levels.
3) Automated Bot Attacks
AI bots perform automated attacks, particularly used in website hacking, DDoS attacks, and credential stuffing (password guessing attacks).
AI Security Solution Response:
• AI-based web application firewall (WAF): AI distinguishes between legitimate users and bots to block malicious bots from accessing websites.
• Anomaly detection using machine learning: AI learns the abnormal traffic patterns of bots and automatically blocks them.
<Case Study>
Cloudflare's AI-based security system blocks billions of bot attacks daily to protect businesses' websites.
➡ Complementary Strategy: AI security systems combined with multi-factor authentication (MFA) provide even stronger security.
2. Advantages and Limitations of AI-based Cyber Security Solutions
AI security solutions can defend against cyberattacks in a much more sophisticated and automated way than traditional security systems. However, because AI also has limitations, collaboration with human experts is necessary.
<Advantages of AI Security Solutions>
✅ Real-time detection and response: AI can detect cyberattacks as soon as they occur and respond automatically.
✅ Continuous learning through machine learning: AI learns new attack patterns to build an increasingly robust security system.
✅ Automatic security updates: AI automatically applies new security patches to keep systems up-to-date.
-- Additional Advantage: AI-based security solutions can automatically analyze threat intelligence to take preventive measures.
<Limitations of AI Security Solutions>
🔹 False positives: AI may misinterpret normal activity as malicious behavior.
🔹 Data dependency: The performance of AI depends on the quality of the trained data, so securing sufficient data is essential.
🔹 Increased AI-powered attacks: Hackers are also using AI to develop techniques to bypass security systems.
🔹 Solution: Collaboration with experts and continuous monitoring are essential when implementing AI security solutions.
3. Future Outlook of AI Cybersecurity
With the advancement of AI technology, the cybersecurity environment is rapidly changing. The following AI-based security technologies will receive attention in the future.
🔹 AI-based automated Security Operations Center (SOC): Systems where AI analyzes security logs and responds to security breaches in real time will be developed.
🔹 Enhanced AI-based threat intelligence: Technologies that allow AI to preemptively learn and prepare countermeasures against new attack methods used by hackers will be introduced.
🔹 Balance between security and privacy: Technologies will be developed that enhance security while also protecting personal information.
🔹 Enterprise adoption cases: Many large companies are adopting AI-based security solutions to prevent data breaches.
Cybersecurity threats are becoming increasingly sophisticated, and AI plays an essential role in detecting and blocking these threats. AI-based solutions are being introduced to address various security issues such as ransomware, phishing, bot attacks, and insider threats, and AI security technology will continue to advance in the future.
It is important for businesses and individuals to actively utilize AI-based security technologies and stay informed about the latest security trends to protect their digital assets.
