Introduction
In today’s cybersecurity landscape, malicious domains and IPs pose a significant threat to organizations. Identifying and mitigating these threats efficiently is essential to minimize potential damage. Manually analyzing and responding to suspicious domains or IPs can be time-consuming and error-prone. SIRP’s Domain Analysis and Response playbook offers a seamless and automated approach to address this challenge.
Challenges Faced
Manual Domain Analysis: Time-consuming processes for enriching domain reputation across multiple sources.
Delayed Threat Response: Prolonged analysis times leave the network vulnerable to exploitation.
Complex Data Correlation: Difficulty in cross-referencing domain and IP data across threat intelligence tools.
Limited Scalability: SOC teams struggle to manage high volumes of suspicious domains and IPs.
How SIRP Solves This
The Domain Analysis and Response playbook integrates multiple tools and processes to deliver an automated and comprehensive threat analysis and response solution.
Domain Enrichment
The playbook uses APIVoid, Virus Total, and AlienVault to analyze the reputation of the provided domain.
If identified as malicious, the playbook takes immediate action to block the domain on the Palo Alto Firewall.
Behavioral Analysis
For domains with unknown reputation, the playbook submits them to Any.run, a sandbox environment.
The detailed sandbox report is automatically sent to the SOC Analyst for review.
IP Reputation Check
The playbook evaluates the IP address associated with the domain using AbuseIPDB and other reputation services.
If flagged as malicious, the IP is automatically blocked on the Palo Alto Firewall.
Streamlined Reporting and Assignment
Outputs such as domain SSL information, domain age, and URL reports from Any.run are compiled.
A task with detailed findings is assigned to the SOC Analyst, ensuring complete visibility and enabling manual intervention if necessary.
Playbook Integrations
This playbook leverages best-in-class integrations to ensure comprehensive threat detection and response:
APIVoid: For domain enrichment and threat intelligence.
AbuseIPDB: To assess the reputation of the associated IP.
AlienVault: For cross-referencing domain threat indicators.
Virus Total: To determine domain and file reputation.
Palo Alto EDL: For enforcing domain and IP blocking.
Any.run: For dynamic sandboxing and behavioral analysis.
