The Persistent Threat of Software Supply Chain Attacks: Lessons Still Unlearned

Karthikeyan Thirumalaisamy

Abstract: The software supply chain represents a major cybersecurity threat which has become one of the most significant dangers in today's digital world. Organizations persist in making basic security mistakes despite major incidents such as SolarWinds, Kaseya and Log4j which exposed fundamental weaknesses in software development and distribution processes. Lessons from past incidents are often not fully understood and integrated to protect critical infrastructure and enterprise software ecosystems from dangerous exposure. This paper examines software supply chain attacks from the previous year through incident analysis to extract valuable lessons from these events. The paper presents practical recommendations to boost software supply chain security resilience and accountability.
