The final component is automated decision-making and remediation, where AIOps takes proactive steps to resolve issues. Whether it’s adjusting firewall rules, implementing network segmentation, or escalating critical threats to security teams, AIOps ensures that responses are swift and accurate.
How AIOps for NGFW Derives Health and Security Information from Device Telemetry Data?
Device telemetry data is at the core of AIOps for NGFW operations. NGFWs generate extensive logs and events that reflect their health and performance. AIOps analyzes this telemetry data to derive insights into how the firewall is performing, identifying any areas of concern such as high CPU usage, packet loss, or abnormal traffic patterns.
Through continuous monitoring and analysis, AIOps can not only detect performance issues but also predict potential failures based on historical data trends. This predictive capability allows organizations to address problems before they impact the network, enhancing the reliability and security of their NGFW infrastructure.
Improving NGFW Observability and Speed
One of the key advantages of AIOps is its ability to significantly improve observability into NGFW performance and the devices connected to the network.
Traditional firewall monitoring methods are often limited in scope, focusing on specific events or incidents. However, AIOps provides a more holistic view of the entire firewall ecosystem, enabling real-time visibility into every aspect of NGFW performance.
With enhanced observability, AIOps can track firewall metrics such as bandwidth usage, throughput, latency, and connection health. Moreover, AIOps extends visibility beyond the firewall itself, monitoring the devices and applications connected to the network to identify potential security risks or performance bottlenecks.
How AIOps Can Help with Network Segmentation and Device Classification to Boost Cybersecurity?
AIOps plays a crucial role in enhancing cybersecurity through network segmentation and device classification. By analyzing network traffic and telemetry data, AIOps can automatically classify devices based on their behavior and usage patterns. This classification enables NGFWs to apply more targeted security policies, ensuring that high-risk devices are subject to stricter controls.
Additionally, AIOps assists in segmenting the network to isolate sensitive or critical assets from less secure areas. Through network segmentation, AIOps reduces the attack surface and limits the potential spread of malware or other security threats, thereby bolstering overall cybersecurity posture.
Reducing Mean Time to Detect (MTTD), Acknowledge (MTTA), and Resolve (MTTR)
One of the primary goals of AIOps in NGFW operations is to reduce key incident response metrics: Mean Time to Detect (MTTD), Mean Time to Acknowledge (MTTA), and Mean Time to Resolve (MTTR). AIOps achieves this by automating the detection and response process, significantly reducing the time required to identify, analyze, and address security incidents.
Through continuous monitoring and real-time data analysis, AIOps rapidly detects anomalies or potential threats, shortening MTTD. Once a threat is identified, AIOps automates the process of acknowledging and prioritizing the incident, leading to a faster MTTA. Finally, AIOps aids in root cause analysis and provides recommendations for remediation, reducing MTTR and ensuring that security incidents are resolved promptly.
How AIOps Performs Root Cause Analysis to Quickly Identify the Source of Issues?
AIOps utilizes machine learning algorithms to perform root cause analysis on detected issues. By analyzing vast amounts of telemetry data, AIOps can identify the underlying factors contributing to performance degradation or security threats. The platform cross-references data from multiple sources to pinpoint the exact source of the issue, whether it’s a misconfigured firewall rule, network congestion, or a malicious attack.
This automated approach to root cause analysis ensures that security teams receive accurate, actionable information, allowing them to resolve issues more efficiently and effectively.
Early Identification of Threats
AIOps continuously monitors NGFW performance in real-time, analyzing device telemetry data to identify vulnerabilities and potential threats. Through machine learning, AIOps can detect abnormal behavior patterns, such as unexpected traffic spikes, unusual access attempts, or deviations from baseline performance metrics.
By proactively identifying these vulnerabilities, AIOps enables organizations to take corrective action before the threat escalates, improving overall network resilience.
How AIOps Uses Cyber Threat Intelligence to Generate Threat Information?
AIOps platforms often integrate with cyber threat intelligence (CTI) sources to enhance their ability to detect and respond to threats. CTI provides valuable information on emerging threats, malware signatures, and attack vectors.
AIOps correlates this threat intelligence with real-time firewall data, generating actionable threat information and enabling NGFWs to apply the latest security updates and countermeasures.
Incident Filtering and Prioritization
In environments with high alert volumes, it is critical to filter and prioritize incidents based on their impact on business operations. AIOps helps by automatically ranking incidents according to their severity, potential risk, and impact on critical systems.
This prioritization ensures that security teams can focus their attention on the most urgent threats, reducing the time spent on low-impact issues.
How AIOps Can Help Prioritize Issues Affecting Critical Business Processes?
For organizations, some security incidents may have a direct impact on critical business processes. AIOps can identify which issues pose the greatest risk to these processes and prioritize them accordingly. By doing so, AIOps ensures that business continuity is maintained and that high-priority incidents are addressed before they cause significant damage.
