| - Continuous Monitoring for Rapid Response: SIEM systems enable real-time tracking of IoT device activity and network traffic, allowing security teams to swiftly detect and respond to incidents. Continuous monitoring ensures that any deviation from regular activity is identified promptly, helping prevent potential breaches before they escalate. This capability is crucial in an IoT ecosystem where device behaviour can vary widely, and new threats can emerge anytime. | * Continuous Monitoring for Rapid Response: SIEM systems enable real-time tracking of IoT device activity and network traffic, allowing security teams to swiftly detect and respond to incidents.

| - Granular Visibility: SIEM systems give organisations a detailed view of their IoT network. This includes monitoring data flows between devices, interactions with backend servers, and communications with external networks. Such visibility ensures that any irregularities, such as unexpected data transmissions or unauthorised access attempts, are flagged immediately for further investigation. | * Granular Visibility: SIEM systems give organisations a detailed view of their IoT network.

| - Log Aggregation from Diverse Sources: SIEM solutions collect logs from multiple sources across the IoT network, including device event logs, network traffic data, application activity, and user access records. This aggregation allows for a holistic network view, making detecting coordinated attacks or patterns that might otherwise go unnoticed easier. | * Log Aggregation from Diverse Sources: SIEM solutions collect logs from multiple sources across the IoT network, including device event logs, network traffic data, application activity, and user access records.

| - Anomaly Detection Through Log Analysis: SIEM systems can recognise deviations from established baselines and identify unusual behaviour indicative of security incidents by analysing logs. For example, a sudden spike in data transfer from a specific device or an influx of failed login attempts could point to a compromised device or a brute-force attack. Advanced SIEM platforms often use machine learning algorithms to enhance anomaly detection, learning from historical data to better differentiate between benign and suspicious activity. | * Anomaly Detection Through Log Analysis: SIEM systems can recognise deviations from established baselines and identify unusual behaviour indicative of security incidents by analysing logs.

| - Behavioral Insights: Logs provide invaluable behavioural insights to help organisations understand typical device operations and spot deviations. These insights enable security teams to identify potentially malicious behaviour, such as IoT devices attempting to connect to unauthorised endpoints or being used as entry points for lateral movement within a network. | * Behavioural Insights: Logs provide invaluable behavioural insights to help organisations understand typical device operations and spot deviations.

| - Automated Alerts for Faster Response Times: A key feature of SIEM systems is the implementation of automated alert mechanisms. These alerts notify administrators in real-time when potential security breaches or abnormal activities are detected. Alerts can be configured based on various criteria, such as access attempts from unrecognised IP addresses, unusual data transfers, or unauthorised changes in device configurations. | * Automated Alerts for Faster Response Times: A key feature of SIEM systems is the implementation of automated alert mechanisms.

| - Customisable Alert Thresholds: Organisations can tailor SIEM alert settings to align with their unique risk profiles and operational needs. Customisable thresholds help filter out noise and focus on high-priority alerts, ensuring that security teams can respond effectively to critical incidents without being overwhelmed by false positives. | * Customisable Alert Thresholds: Organisations can tailor SIEM alert settings to align with their unique risk profiles and operational needs.

| - Facilitating a Coordinated Incident Response: With centralised data and real-time alerting, SIEM systems provide the tools needed to streamline the incident response process. Security teams can investigate alerts quickly using the contextual data provided by SIEM logs, enabling them to trace the source of a breach, assess its scope, and take corrective action. This coordinated approach minimises the potential damage and downtime associated with security incidents. | * Facilitating a Coordinated Incident Response: With centralised data and real-time alerting, SIEM systems provide the tools needed to streamline the incident response process.

| - Enhanced Threat Detection: Continuous monitoring, log analysis, and alert mechanisms enable SIEM systems to detect threats that might bypass traditional security measures. This is especially important in IoT environments where conventional antivirus solutions may not be feasible due to limited device processing power. | * Enhanced Threat Detection: Continuous monitoring, log analysis, and alert mechanisms enable SIEM systems to detect threats that might bypass traditional security measures.

| - Compliance and Reporting: Many industries are subject to regulations that require organisations to maintain comprehensive logs and audit trails. SIEM systems support compliance by automating the collection and storage of logs, providing clear evidence of security measures, and generating reports needed for regulatory adherence. Compliance reporting features help organisations demonstrate that they are meeting data security and privacy industry standards. Thus, SIEM systems can enable organisations to generate reports that can be presented to internal and external security auditors to prove that they comply with regulatory requirements. | * Compliance and Reporting: Many industries are subject to regulations that require organisations to maintain comprehensive logs and audit trails.

| - Proactive Threat Hunting: Besides automated monitoring, SIEM systems empower security teams to conduct proactive threat hunting. Analysts can use the system's search and query capabilities to explore logs and uncover potential threats that might not have triggered automatic alerts, allowing for preemptive mitigation measures. | * Proactive Threat Hunting: Besides automated monitoring, SIEM systems empower security teams to conduct proactive threat hunting.
