How to achieve software supply chain security
Software supply chain attacks have become increasingly common in recent years, growing by more than 300% in 2021.(1) In these attacks, threat actors compromise the components supplied by third parties that a company uses to build, patch, or certify a software application. Rather than targeting a company directly, attackers search for supply chain partners with poor security practices, exploiting vulnerabilities in the code or tools these vendors supply to the target company. By compromising code, development tools, firmware components, or certificates supplied by vendors, attackers can more easily gain access to well-protected organizations.
Since the software supply chain may be compromised at any time, traditional vendor risk monitoring solutions like point-in-time questionnaires are of little help in identifying evolving risk. Improving software supply chain security requires continuous monitoring of vendors, starting with the procurement and onboarding process and continuing throughout the vendor/client relationship. That’s where Bitsight can help. Bitsight for Supply Chain Cybersecurity Risk Management leverages Bitsight’s industry-leading security ratings to effectively reveal, remediate, and monitor software supply chain risk.
4 best practices for securing your software supply chain
As the supply chain becomes more interconnected, threat actors find new opportunities to breach an organization’s defenses by attacking third-party vendors with the weakest security. These best practices can help to improve digital resilience in the supply chain and combat third-party risk.
Validate vendors’ security posture before and after onboarding
Rather than relying on security questionnaires that only provide a point-in-time snapshot of cyber health as reported by vendors, organizations can use security ratings to quickly measure each vendor’s security posture against acceptable risk thresholds and to simplify software supply chain security by grouping vendors based on their risk and criticality to the business.
Continuously monitor software supply chain security
Because a vendor’s risk profile may change at any time, organizations should continuously monitor the security performance of all supply chain partners. Security ratings provide a quick way to identify new risks, such as insecure access ports, unpatched systems, or the presence of malware.
Track fourth-party risk
Monitoring the suppliers and partners of third-party vendors delivers deeper visibility into supply chain risk. To improve software supply chain security, organizations need solutions to issue alerts when security incidents are discovered in the extended supply chain.
Use business terms to report on supply chain risk
Achieving software supply chain security requires everyone in an organization to be on the same page about the importance of investing in security measures – including the Board of Directors. To provide easy-to-digest metrics that board members without a technical background can easily understand, CISOs should characterize the benefits of supply chain risk management in business and financial terms rather than simply in cybersecurity metrics.
