Case Study: Infrastructure PT
Background:
The objective was to identify vulnerabilities and weaknesses in the infrastructure that could be exploited by malicious actors. The scope included external and internal network components, servers, and associated systems.
Challenges:
- Complex Infrastructure
- Black Box PT
Objectives:
- Identify and remediate vulnerabilities in the network infrastructure to prevent unauthorized access and data breaches
- Assess the effectiveness of network segmentation and isoThreat Review & Threat Modelling
- Evaluate the security of servers, including operating systems and applications
- Test the resilience of critical systems against potential cyber threats and attacks
Methodology:
- Information Gathering
- Vulnerability Scanning
- Network Mapping
- Internal Testing
- Server Security Assessment
- Wireless Network Testing
Findings:
- Outdated Server Software
- Weak Network Segmentation
- Insufficient Access Controls
- Unsecured Wireless Network
- Vulnerable services
- Open Ports
- Misconfigurations
- Missing patches/updates
- Privilege escalation
Recommendations
- Patch Management: Implement a robust patch management process to regularly update and patch server software
- Enhance Network Segmentation: Strengthen network segmentation to limit lateral movement between segments
- Access Control Improvements: Implement stronger access controls for servers, including proper user permissions and authentication mechanisms
- Secure Wireless Networks: Secure wireless networks with strong encryption, enforce strong authentication, and regularly update wireless security controls
Retesting:
A follow-up infrastructure penetration test was conducted to verify the effectiveness of the remediation efforts. All identified vulnerabilities were successfully remediated, and no new critical issues were discovered.
Conclusion:
The infrastructure penetration testing provided by addressing the identified vulnerabilities promptly, the company demonstrated its commitment to maintaining a secure and resilient infrastructure against potential cyber threats
