MCP Servers Still Run Critical Infrastructure-Here's How to Secure Them | HackerNoon
Briefly

MCP (Master Control Program) servers are vital in industries requiring high reliability, operating largely unnoticed in the background. These systems, historically developed by Burroughs Corporation and now under Unisys, power essential applications in finance, government, and industry. The Vulnerable MCP Project serves to educate security professionals by simulating production environments with known vulnerabilities, aiming to enhance protection measures for legacy systems. As many businesses continue to rely on these outdated infrastructures, they present attractive targets for attackers, emphasizing the importance of ongoing security attention.
There exists another realm which silently works in the backend systems of multiple industries: MCP servers.
The Vulnerable MCP Project is meant to mimic a production MCP server environment with deliberately open vulnerabilities for the sake of educating system admins.
Legacy systems are usually forgotten in security plans, yet attackers adore these systems because they’re minimally monitored and often left without updates.
MCP is one of the first high-level language-based OSes and is commonly implemented in financial markets, government computers, and industrial facilities.
