# Automation
[![[Pasted image 20251104230349.png]]](https://soc-expert.de/From+Logging+to+Alerting+and+Beyond)
**Automation** refers to the use of scripts, workflows, or integrated tools to **automatically respond to correlated events or alerts**, without requiring manual intervention for every step.
> [!note] Automation in SIEM involves:
>
> - **Automatically executing predefined actions** when certain alerts or correlated events occur.
> - **Reducing manual workload** for security analysts.
> - **Speeding up response times** to potential threats.
## How Automation Improves Correlated Events or Alerts
|Benefit|Description|
|---|---|
|**Faster Response**|Automatically blocks IPs, disables accounts, or isolates endpoints when a threat is detected.|
|**Reduced Alert Fatigue**|Filters out false positives or low-priority alerts, so analysts focus on real threats.|
|**Consistency**|Ensures the same response is applied every time a specific threat pattern is detected.|
|**Scalability**|Handles large volumes of alerts without overwhelming human analysts.|
|**Enrichment**|Automatically gathers additional context (e.g., threat intelligence, user behavior) to help analysts make better decisions.|
## Runbooks
In the context of **automation and orchestration** within **SIEM** or broader **security operations**, a **runbook** is a **predefined set of instructions or workflows** that guide how to respond to specific alerts, incidents, or operational tasks, often in a semi or fully automated way.
### Runbook in Automation
**Automated runbooks** execute tasks like:
- Blocking IP addresses
- Disabling user accounts
- Quarantining endpoints
- Sending notifications
- Creating tickets
These actions are triggered by alerts or correlated events without human intervention.
### Runbook in Orchestration
**Orchestrated runbooks** coordinate multiple systems and steps:
- Enrich alert with threat intelligence
- Check user behavior history
- Notify SOC team
- Escalate to incident response if needed
- Document actions in a case management system
These workflows may include decision points, conditional logic, and human approvals.
## Example: Automated Workflow for a Brute Force Attack
1. **Correlation Rule Triggers**:
- 10 failed login attempts from the same IP within 5 minutes.
2. **Automation Kicks In**:
- Enriches the alert with geolocation and threat intel data.
- Blocks the IP at the firewall.
- Sends an alert to the SOC team via email or Slack.
- Opens a ticket in the incident response system.
## Common Automation Actions in SIEM
- **IP blocking or firewall rule updates**
- **User account lockout or password reset**
- **Quarantine of infected endpoints**
- **Notification via email, SMS, or chat**
- **Ticket creation in ITSM tools (e.g., ServiceNow, Jira)**
- **Running forensic scripts or memory dumps**
