As organizations continue to digitalize, the threat landscape is continuously evolving, requiring more intellectual and automated systems to handle the growing cybersecurity threats. Fortunately, with advancements in technology, Artificial Intelligence (AI) has been utilized to enhance threat mitigation. Microsoft 365 and Azure Sentinel offer groundbreaking solutions to tackle cybersecurity threats, enabling organizations to detect, analyse and deal with threats in real-time.
AI-powered threat mitigation operates on the foundation of identifying patterns and anomalies. This involves the system learning what normal behavior looks like, then flagging any deviations from this norm. This automated anomaly detection helps to identify potential threats that may otherwise be missed.
Azure Sentinel and Microsoft 365 for Threat Mitigation
Azure Sentinel is Microsoft’s solution to Security Information and Event Management (SIEM) which utilizes artificial intelligence (AI) to boost threat identification and response. By integrating Azure Sentinel and Microsoft 365, organizations can leverage real-time security analytics for threat detection, enhancing their cybersecurity posture.
These AI-based solutions work 24/7, offering constant safety from multiple forms of threats, including data breaches, identity theft, malware attacks, and others.
Real-Time Analytics and Threat Detection
Azure Sentinel collects data across all the users, applications, devices, and infrastructure, both on-premises and multiple clouds, and analyzes it for threats. It uses advanced SIEM and Security Orchestration Automated Response (SOAR) solutions for threat mitigation. Microsoft 365 offers advanced security capabilities to safeguard data and provide threat protection. By integrating Microsoft 365 with Azure Sentinel, the effectiveness of these solutions is amplified.
Automated Incident Creation and Investigation
Azure Sentinel uses AI for automated incident creation. It applies machine learning models to detect threats and creates an incident that provides an overview of the threat. Automated investigation begins immediately after the threat is detected. Azure Sentinel can investigate incidents, track the full scope of the attack, and propose remediation steps.
Threat Intelligence
Threat intelligence is vital in proactive threat hunting as it gives insights into the threats seen in the organization’s environment. Azure Sentinel and Microsoft 365 come with in-built threat intelligence that provides analytics and insights into known threats. The intelligence is fed from a variety of sources, including Microsoft’s threat intelligence, which analyzes a vast amount of data globally for emerging threats.
Examples of AI-based Threat Mitigation using Azure Sentinel and Microsoft 365
An example of how AI-based threat mitigation can work with these software solutions can include detecting and mitigating a phishing attack. If an employee, for instance, receives an email that Sentinel’s AI system analyses and flags as potentially harmful, it will block access to that email and notify both the user and the system administrators. In the background, Azure Sentinel’s threat intelligence will attempt to identify the sender and potentially block all other attempts from that party, thus mitigating the risk.
Similarly, Azure Sentinel identifies common signs of data exfiltration from the network and can take immediate action when such an event occurs. It can identify users downloading and transmitting large volumes of data and can proactively provide alerts and even block the activity if deemed harmful.
Microsoft 365 and Azure Sentinel, leveraging AI for threat mitigation, are a robust combination for enhancing organizational security. With continuous monitoring and analysis of data, proactive threat detection, rapid response, and remediation of enterprise-wide threats, these innovative solutions provide robust security coverage. By employing such technology, organizations can ensure their cybersecurity measures are effective and reliable, providing much-needed security in an increasingly digital age.
