COBOL, the veteran among programming languages, continues to form the backbone of critical infrastructures in many industries. But while the systems reliably perform their services, an underestimated risk often slumbers beneath the surface: security vulnerabilities in the aging codebase.
Historical Legacy Meets Modern Threats
COBOL systems were developed at a time when cybersecurity was still a marginal topic. As a result, many applications have fundamental security flaws that make them an attractive target for cybercriminals. At the same time, attack methods are becoming increasingly sophisticated, presenting companies with new challenges.
Vulnerabilities in Focus: Where Do the Dangers Lurk?
Lack of Security Updates: Many COBOL systems have not been updated for years, leaving known vulnerabilities unpatched.
Insecure Programming Practices: Original COBOL development often did not follow today's security standards, which can lead to vulnerabilities in the code.
Lack of Security Monitoring: Tools and processes for effectively monitoring COBOL systems for security incidents are often lacking.
Waking the Giant: Strategies for Enhanced COBOL Security
Inventory and Risk Analysis: Companies need to identify their COBOL applications, analyze vulnerabilities, and assess the risk potential.
Security Updates and Patches: It is essential to install security updates and patches promptly to close known vulnerabilities.
Code Review and Refactoring: Review existing COBOL code for security vulnerabilities and modernize it if necessary.
Security Monitoring and Logging: Implement tools and processes to detect and log suspicious activities in COBOL systems.
Training and Awareness: Train employees on how to handle COBOL systems and raise awareness of security issues.
Conclusion
The security of COBOL systems is not a task to be taken lightly. With a proactive approach that considers the specific challenges of these systems, companies can protect their critical data and applications while continuing to leverage the benefits of proven COBOL technology. It's time to wake up the sleeping giant and give it a modern security corset.
