Case Study 1: Darktrace and Threat Detection
Darktrace, founded in 2013, has emerged as a pioneer in cyber defence technology, utilizing machine learning at its core. Their flagship technology, the Enterprise Immune System, is inspired by the human body’s immune system and is designed to detect and respond to cyber threats due to its self-learning capability.
Real-world Incident: In an incident involving a biotechnology company, Darktrace’s technology was instrumental in identifying and thwarting an insider threat. The system flagged unusual data transfer on the company’s network, which was traced back to an employee who was transmitting sensitive data outside the network. The employee, who was resigning, attempted to take proprietary data with them. Darktrace’s system not only identified the threat in real-time but also provided a detailed account of the user’s actions, which were contrary to their usual behaviour patterns. This incident underscores the efficacy of ML in identifying subtle, insider threats that typically evade traditional security measures.
Case Study 2: SparkCognition and DeepArmor
SparkCognition, an AI company established in 2013, developed DeepArmor, an endpoint protection platform that employs machine learning to secure devices against malware attacks. DeepArmor is designed to offer more robust protection than traditional, signature-based antivirus programs by using machine learning to identify and block known and unknown malware strains.
Real-world Application: In a notable demonstration of its capabilities, DeepArmor was subjected to a range of malware samples, including the infamous WannaCry ransomware. Traditional, signature-based systems failed to identify the ransomware because it was a zero-day attack –malware that hadn’t been seen before. In contrast, DeepArmor identified and quarantined the ransomware based on its behaviour and code patterns. This instance highlights how AI-driven security solutions offer superior protection by identifying malware based on attributes beyond mere signatures.
Case Study 3: Mastercard and Decision Intelligence
Mastercard, a leader in global payments, has integrated AI into its security with a platform called Decision Intelligence. This system uses machine learning to analyze transaction details, such as customer habits, to make more informed decisions about whether transactions are legitimate or potentially fraudulent.
Real-world Impact: One of the issues in digital transaction processes is false declines – legitimate transactions that are declined due to suspected fraud. For retailers and customers alike, this is a source of frustration and lost revenue. Mastercard’s Decision Intelligence has significantly reduced these incidents. In one scenario, a customer made several high-value purchases in a short period, which triggered fraud alerts with traditional systems. However, Decision Intelligence, recognizing the customer’s consistent location and using the purchasing history, allowed the transactions. This example demonstrates how AI can lead to more nuanced decision-making, reducing false positives, and improving the customer experience.
These case studies illustrate the practical benefits and real-world impact of AI and ML in cybersecurity. They highlight not only the defensive capabilities of these technologies but also their potential to enhance operational efficiency and user experience.
