Recent high-profile breaches have highlighted the vulnerabilities present within supply chains and underscored the importance of robust cybersecurity measures. This blog post will explore what supply chain attacks are, analyze notable breaches, and draw lessons that organizations can apply to strengthen their defenses.
Understanding Supply Chain Attacks
What Are Supply Chain Attacks?
Supply chain attacks occur when cybercriminals infiltrate an organization by targeting its suppliers or service providers. The attackers exploit vulnerabilities in third-party software, hardware, or services to gain unauthorized access to the organization’s systems and data.
