Understanding External Infrastructure Penetration Test:

An External Infrastructure Penetration Test focuses on assessing an organisation’s external-facing assets, including web applications, servers, and network devices. The primary objective is to identify vulnerabilities that malicious actors could exploit from outside the organisation’s perimeter.

During this assessment, cybersecurity professionals simulate real-world attack scenarios to pinpoint weak points, misconfigurations, or outdated systems that might be susceptible to external threats. By conducting these tests, organisations gain insights into potential entry points that attackers could leverage, ensuring they can implement necessary security measures to safeguard their digital assets.

Criteria for Determining the Need for an External Penetration Test:

  1. External-Facing Assets: Evaluate the number and nature of assets (websites, applications, servers) accessible from outside the organisation’s network perimeter.
  2. Industry Regulations: Determine if your industry compliance standards necessitate regular external security assessments to meet regulatory requirements.
  3. Previous Breaches: If your organisation has experienced external breaches or unauthorised access attempts in the past, it indicates a need for regular external penetration tests.
  4. Business Importance: Assess the criticality of your external-facing systems and data. High-value assets, such as customer databases or transactional platforms, typically require frequent testing.
  5. Organisational Growth: If your company has recently expanded its online presence, launched new websites, or integrated third-party services, it heightens the need for external penetration testing.
  6. Competitive Landscape: If competitors or similar organisations in your sector have experienced external cyberattacks, it’s essential to proactively assess and fortify your external defences.
  7. Technology Updates: Any significant changes or updates to your external infrastructure, such as new software deployments or system migrations, should trigger a reevaluation and potential penetration test.

Intriguing and Innovative approaches to uncovering vulnerabilities:

  1. Traffic Redirection Techniques: Employ techniques like DNS poisoning or BGP hijacking simulations to evaluate the resilience of systems against traffic redirection attempts.
  2. Social Engineering Blends: Integrate sophisticated social engineering tactics with technical assessments, combining phishing simulations with network probing to test human and system vulnerabilities concurrently.
  3. IoT Ecosystem Probing: Focus on the Internet of Things (IoT) devices connected to external networks, exploiting potential vulnerabilities in smart devices, wearables, or other connected endpoints.
  4. API Vulnerability Testing: Specifically target and assess external Application Programming Interfaces (APIs) for vulnerabilities, ensuring that data transfers and integrations with external systems remain secure.
  5. Serverless Architecture Assessment: Evaluate serverless functions and architectures, checking for misconfigurations, insecure deployments, or inadequate permissions that could be exploited.
  6. Cloud Infrastructure Exploitation: Dive deep into cloud environments like AWS, Azure, or Google Cloud, examining configurations, permissions, and storage solutions for potential misconfigurations or exposed resources.
  7. Third-party Vendor Assessment: Probe external vendors, partners, or integrations that have access to your network or share data, ensuring they adhere to security best practices and don’t introduce vulnerabilities.
  8. Mobile Application Testing: Extend the scope beyond traditional web assets by assessing mobile applications, scrutinising both the client-side and server-side components for vulnerabilities.
  9. Web of Trust Exploitation: Investigate third-party plugins, extensions, or widgets embedded in websites or applications, as they can introduce vulnerabilities or act as potential attack vectors.
  10. Evasive Techniques: Use advanced evasion techniques during testing to simulate sophisticated attackers, ensuring that defensive mechanisms can detect and respond to evasive manoeuvres effectively.
  11. Deep Web and Dark Web Monitoring: Monitor mentions or leaks related to your organisation on deep web forums or dark web marketplaces, using this intelligence to simulate targeted attacks or understand potential exposures.
