Securing Sensitive Information with Artificial Intelligence
The field of information security plays a crucial role in safeguarding a company’s critical data, personal affairs, and corporate secrets from falling into the wrong hands. This sector defends against data leaks, hacks, corruption of files, and various kinds of cyber-attacks. Both commercial and government entities must protect their data from espionage and potential malicious actors within their own ranks.
Existing methods for detecting illicit users are often time-consuming and inefficient. Fortunately, advances in artificial intelligence (AI) offer a promising solution, providing the capability for rapid data analysis.
Researchers from Perm National Research Polytechnic University (PNIPU) have trained a neural network to quickly and accurately identify illegal network users, strengthening Russia’s information sovereignty. This development, published in the “Master’s journal,” is part of the “Priority 2030” strategic academic leadership program.
Event Logs as Tools for Cybersecurity
Event log files are critical for ensuring company information security. These databases contain details about various system or network events related to security, enabling the analysis and tracking of activities, identifying potential threats, and detecting abnormal behaviors to protect data.
With large corporate systems generating up to a million log entries daily, automating the analysis of such vast amounts of unstructured data has proven resource-intensive and often delayed. Real-time monitoring of system logs is essential to detect anomalies and promptly respond to security incidents, reducing associated risks.
To address this challenge, Perm Polytech scientists suggest employing AI. By analyzing extensive user activity data within information systems, they have trained a neural network to recognize the distinct behavior of intruders compared to legitimate users.
Efficient and Reliable Intrusion Detection AI Model
The polytechnic researchers opted for a perceptron-based computer model, a simple yet effective neural network type. Binary data representing system users served as input parameters, with ‘0’ indicating legitimate users and ‘1’ denoting illegal ones. The neural network was trained using over 700 data types from more than 1,500 users.
Comparative analysis against another neural network type revealed that the perceptron-based network more accurately distinguishes between illegal and legitimate users. This novel AI method proved to significantly reduce the chances of both types of errors – mistaking a legitimate user for an intruder and vice versa – by 20%. This implementation promises to boost reliability and assist in detecting unauthorized users within information systems.
The Perm Polytech development demonstrates that an AI-based method is particularly well-suited for enterprise applications. It requires minimal memory, performs rapidly, and can analyze considerable data volumes effectively.
Key Challenges in AI-based User Anomaly Detection
The integration of AI-based user anomaly detection systems into cybersecurity presents several challenges:
1. Data Privacy: Handling vast quantities of user data for training AI models may involve sensitive information, creating privacy concerns and requiring robust data handling and protection protocols.
2. False Positives/Negatives: Although AI can improve accuracy, there’s still a risk of false positives (legitimate users labeled as threats) and false negatives (actual threats undetected), necessitating ongoing tuning and evaluation of the system.
3. Adversarial Attacks: Adversaries may use sophisticated tactics to fool AI systems, such as generating inputs that cause the model to make incorrect decisions, known as adversarial attacks.
4. Complexity of Cyber Threats: Cyber threats are constantly evolving, requiring AI systems to be adaptive and regularly updated to recognize new patterns of anomalies.
Controversies Associated with AI in Cybersecurity
One of the controversies in this domain pertains to the balance between automated security and human oversight. AI systems operate on predefined algorithms, and over-reliance on these systems could potentially create blind spots or vulnerabilities that a skilled human might catch.
Advantages of AI-based User Anomaly Detection
– Efficiency: AI can analyze large datasets much faster than human operators, enabling real-time threat detection and response.
– Scalability: AI systems can scale with the size of the enterprise, handling increased loads without compromising performance.
– Accuracy: With proper training, AI models can achieve high degrees of accuracy in distinguishing between normal and anomalous user activities.
Disadvantages of AI-based User Anomaly Detection
– Initial Cost: Implementing AI solutions often requires significant initial investment in technology and expertise.
– Complexity: Designing, implementing, and maintaining AI systems for cybersecurity is complex and requires skilled personnel.
– Dependence on Data: The performance of AI models is heavily dependent on the quality and volume of data used for training, and in some cases, access to such data may be limited or biased.
