Key Incidents and Lessons

SolarWinds Attack (2020)

One of the largest supply chain attacks in which malicious code was hidden within software updates for SolarWind’s Orion platform. The bug was a clear miss on the part of Yubico – and one that demonstrates why it is important to secure build environments for software development, as well as distribution. However, the attack code is inserted in a very early phase into the software and use techniques outside of traditional security processes. Breaks show requirements for comprehensive monitoring solutions – status during development!.

Equifax Data Breach (2017)

Caused by a missed security patch for a known vulnerability in the Apache Struts framework used on Equifax website. Outshift by Cisco Furthermore, it underscores vulnerabilities in third-party components to mitigate — The critical part being keeping those up-to-date and patched.​ 

Microsoft’s Approach

Microsoft is partnering with the OpenSSF Secure Supply Chain Consumption Framework (S2C2F) delivered through Bill of Materials Data Standard to improve our supply chain security. This framework also intended to solve dependency confusion issues introduced security checks including typo-squatting and vulnerability scanning during component updates. This type of practice is what it takes to keep software supply chain seriously, especially on larger scales.​

Strategic Implementations

To this end, the following are among other strategic measures that companies can put in place to protect their software supply chains:

Improved Features For Verification Process

Like what was done by Microsoft with having an exhaustive verification process for all software updates and development tools applying S2C2F framework which encompasses multiple control points throughout various compartments of the Software Supply Chain. 

Real-Time Threat Detection

On the lookout for real-time monitoring and threat detection tools or techniques that can be used to detect any future threats at an initial stage. With this, the security breach in the supply chain​ will not go further.

Education and Awareness

Companies need to invest in training the workforce on vulnerabilities/solutions regarding Supply Chain Security. Such a cultural shift can also improve an organization’s security posture overall​.​
