Alert Dashboard

What is an Alert Dashboard?

An alert dashboard is a central interface that displays security alerts in real time from various sources such as SIEM (Security Information and Event Management), EDR (Endpoint Detection and Response), firewalls and other security systems. The dashboard provides an overview of a company’s current threat situation by consolidating security-related incidents and sorting them according to severity and relevance. It enables security teams to efficiently monitor and prioritize threats. The main purpose is to provide a centralized location where IT security managers can see which threats are most urgent, how they occur and how they could potentially spread. It facilitates rapid incident response, escalation and the initiation of countermeasures.

How are alerts prioritized?

The prioritization of alerts is based on several factors:

• Threat severity: Alerts are categorized as “critical”, “high”, “medium” and “low”. This classification is based on the potential impact on the company, for example whether it is a serious security vulnerability or a minor anomaly.
• Risk and threat modeling: Tools such as SIEM or EDR systems analyze the risk by comparing the threat with existing vulnerabilities and the potential impact on the network. Critical threats such as ransomware attacks are prioritized higher than simple policy violations.
• Business context: Systems that affect business-critical applications, such as production servers or financial systems, are prioritized higher, as an incident in these areas could have a significant impact on the company.
• Frequency and repetition: An alert that occurs repeatedly or correlates with other alerts is considered a higher risk. Systems that analyze behaviour patterns can identify these correlations and adjust the priority accordingly.
• Previous incidents: If a similar incident has led to a security incident in the past, such an alert is often automatically prioritized higher.

How can I recognize and reduce false positives?

False positives are a common problem in security operations as they can lead to alert fatigue and mask real threats. The following measures can be taken to recognize and reduce false positives:

• Regular adjustment of alert rules: Security systems such as SIEM and EDR are based on predefined rules that can be configured to trigger alerts. These rules need to be continuously adjusted to ensure that they match actual threats and normal behavior patterns.
• Fine-tuning sensitivity: Systems that react too sensitively to certain activities often generate unnecessary alarms. This can be avoided by adjusting the sensitivity without increasing the risk.
• Behavior-based analysis: The use of machine learning and anomaly detection systems helps to differentiate between normal and unusual behavior. False positives are often caused by legitimate activities that are incorrectly classified as threats. Learning systems can reduce the risk.
• Alert tuning and whitelisting: Known, legitimate activities can be whitelisted in many systems to exclude them from future alerts. This prevents the same false positives from appearing again and again.
• Correlation of events: More advanced systems can correlate events to determine whether a combination of incidents actually represents a threat. A single alarm could be a false positive, but in combination with other events it can be classified as a critical threat.

Which metrics and KPIs should I monitor on the dashboard?

Monitoring KPIs (Key Performance Indicators) on an alert dashboard is essential for monitoring the security situation and the effectiveness of the security team. Important KPIs that should be monitored include:

• Time to Detection (TTD): The time that elapses between the occurrence of a threat and its detection. A short TTD is crucial in order to be able to initiate countermeasures in good time.
• Time to Response (TTR): This metric measures the time it takes the security team to respond to an alert. A fast TTR minimizes potential damage.
• Number of open alerts: Shows how many alerts have not yet been investigated or processed. A high number of open alerts indicates a possible overload or inefficient prioritization.
• False positive rate: This metric measures the proportion of alerts that turn out to be harmless. A high false positive rate indicates the potential to improve the effectiveness of the dashboard through fine-tuning.
• Alert distribution by severity: This metric provides an overview of how many critical, high, medium and low alerts are currently in the system. It helps to focus the team’s attention on the most serious threats.
• Mean Time to Resolve (MTTR): This metric measures the average time it takes to resolve an incident. A lower MTTR indicates a more efficient incident response.

How can I customize my dashboard?

The customizability of an alert dashboard is a critical factor in its effectiveness, as every company has different requirements. Here are some options for customization:

• Custom filters: You can configure the dashboard to only display alerts for specific systems, user groups or threat types. This makes it easier to focus on relevant incidents.
• Dashboards for different teams: Different teams within a company have different priorities. A SOC may need a detailed view of all security-related incidents, while management may need a more aggregated, strategic overview. Dashboards can be customized for different target groups.
• Visualization and metrics: Many dashboards allow you to add charts, graphs and heatmaps to display metrics such as TTD, TTR, number of open alerts or threat distribution in a clear format.
• Alert thresholds: Adjust thresholds at which the system triggers notifications or escalations. For certain incidents, it may make sense to activate immediate alerts, while other incidents only need to be monitored.
• Integration of SOAR solutions: Routine tasks can be automated through the integration of SOAR (Security Orchestration, Automation and Response) systems. For example, a false positive can be closed automatically or an incident can be forwarded directly to the incident response team.

Which integrations are possible?

Most modern dashboards integrate with a variety of security tools and platforms to create a comprehensive and seamless security environment:

• SIEM systems: Systems such as Splunk, IBM QRadar or ArcSight can be integrated to ensure a centralized view of all security-related incidents.
• EDR solutions: Endpoint detection and response tools such as CrowdStrike or Microsoft Defender provide detailed data on endpoint activity and threats.
• SOAR platforms: SOAR solutions such as Phantom or Demisto enable the automation of response processes and integration with incident response systems and ticketing tools.
• Ticketing systems: Systems such as JIRA or ServiceNow can be integrated to standardize and document the processing of security incidents.

How do I keep track of a large number of alerts?

With a large number of alerts, it is essential to have a structured and efficient approach:

• Automation: By integrating SOAR solutions, routine tasks such as closing false positives can be automated, reducing the volume of open alerts.
• Alert correlation: SIEM systems are able to correlate events and thus help security managers to recognize related incidents. This reduces the number of isolated alerts and focuses on truly relevant threats.
• Filters and prioritization: Setting filters and consistent prioritization according to severity and business impact helps to quickly identify critical alerts.
