TL;DR
In today’s digital landscape, supply chain attacks present serious security threats. Comprehensive vendor risk assessments are critical for strengthening security within your Attack Surface Management (ASM) framework. This guide offers actionable strategies and real-world examples to help you reduce exposure to these threats.
Introduction
In our highly connected digital era, supply chain attacks have become a significant concern for businesses worldwide. These attacks exploit vulnerabilities in third-party vendor systems, making it essential for organizations to enforce stringent vendor risk assessments. This blog explores why these assessments are indispensable in fortifying systems through effective Attack Surface Management (ASM).
Understanding Supply Chain Attacks
Supply chain attacks occur when cybercriminals exploit weaknesses within third-party vendors’ software or services.
Example
A prominent case is the SolarWinds breach, where hackers injected malicious code into a widely used software update, impacting numerous organizations globally. This case underscores the significant risks associated with vendor vulnerabilities.

Why Vendor Risk Assessments Matter
Vendor risk assessments allow organizations to detect potential security gaps within their supply chain proactively. By scrutinizing each vendor’s security practices, businesses can:
- Ensure compliance with industry standards.
- Reduce exposure to potential threats.
Core Message
To guard against supply chain attacks, companies must embed vendor risk assessments within their ASM processes. Evaluating vendors’ security posture enables proactive risk mitigation and reinforces the organization’s overall security posture.
Steps to Conduct a Vendor Risk Assessment
1. Identify and Prioritize Vendors
- List all third-party vendors.
- Categorize them based on data access levels and their potential impact on your organization.
2. Evaluate Vendor Security Practices
- Assess vendors’ security protocols, such as:
- Data protection measures.
- Incident response plans.
- Compliance with industry standards.
3. Assessment Tools and Techniques
- Conduct initial scans using tools like OWASP ZAP or Nessus.
- Perform in-depth manual assessments with Red Team exercises.
Example Code for Vulnerability Mitigation (Python):
import requests
def check_vulnerability(url):
try:
response = requests.get(url)
response.raise_for_status()
if "vulnerable" in response.text:
return "Action required"
return "Secure"
except requests.exceptions.RequestException as e:
return f"Error: {e}"
url = 'http://examplevendor.com'
print(check_vulnerability(url))4. Continuous Monitoring and Engagement
- Leverage tools like SecureLayer7’s API scanner for continuous monitoring.
- Regularly perform Red Team exercises to uncover vulnerabilities.
Use Case Example
A financial institution working with cloud and payment processing vendors incorporated vendor risk assessments into its ASM protocol. The company identified high-risk vendors with weak encryption practices. By collaborating with these vendors, the institution improved security measures and significantly reduced exposure to supply chain risks.
Conclusion
Protecting against supply chain attacks requires ongoing diligence. By integrating vendor risk assessments into your ASM strategy, your organization can:
- Gain critical insights into third-party risks.
- Proactively defend against evolving digital threats.
Vendor audits should be a recurring process, fostering a culture of security awareness. Stay vigilant, nurture security-minded partnerships, and proactively defend your organization against the evolving landscape of digital threats.
