CISA and FBI Update Cybersecurity Guidance: Key Takeaways for Software Manufacturers

2025-01-22

In an era where cyber threats are becoming increasingly sophisticated, the importance of robust cybersecurity practices cannot be overstated. Recognizing this, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) have recently updated their guidance on risky software security practices. This revised document, titled Product Security Bad Practices, aims to help software manufacturers—particularly those serving critical infrastructure—identify and mitigate vulnerabilities that could lead to devastating cyberattacks. The updated guidance incorporates valuable feedback from a public comment period, making it a more comprehensive and actionable resource for the industry.

the Updated Guidance

The Product Security Bad Practices guidance outlines a range of security practices deemed exceptionally risky and provides recommendations for addressing them. While the document is non-binding, it serves as a critical reference for software manufacturers, urging them to prioritize security throughout the product development lifecycle. Key areas of focus include:

1. Product Properties: Avoiding the use of memory-unsafe languages, default passwords, and components with known vulnerabilities.
2. Security Features: Implementing multi-factor authentication (MFA), ensuring proper logging, and publishing Common Vulnerabilities and Exposures (CVEs) with Common Weakness Enumerations (CWEs) in a timely manner.
3. Organizational Processes and Policies: Establishing robust policies to address vulnerabilities, including timely patching of flaws listed in the Known Exploited Vulnerabilities (KEV) catalog.

Following a 45-day public comment period, CISA incorporated feedback from 78 submissions, resulting in several updates to the guidance. These include:
– The addition of three new bad practices: hardcoded credentials, the use of insecure or outdated cryptographic functions, and inadequate product support.
– Enhanced examples for preventing SQL injection and command injection vulnerabilities.
– Updated language in the MFA section, emphasizing the need for phishing-resistant MFA, particularly for operational technology (OT) products.

The guidance is intended for a broad audience, including developers of on-premises software, cloud services, SaaS, OT products, and embedded systems. CISA and the FBI emphasize that all software manufacturers should review the document and avoid the outlined bad practices, signaling to customers their commitment to secure-by-design principles.

What Undercode Say:

The updated Product Security Bad Practices guidance from CISA and the FBI is a significant step forward in addressing the growing cybersecurity challenges faced by software manufacturers. By incorporating public feedback and expanding on key areas, the document provides a more comprehensive framework for identifying and mitigating risks. Here’s a deeper analysis of its implications:

1. Focus on Memory-Safe Languages:

The guidance’s emphasis on avoiding memory-unsafe languages like C and C++ highlights a critical issue in software development. Memory-related vulnerabilities, such as buffer overflows, are among the most exploited weaknesses in cyberattacks. By encouraging the adoption of memory-safe languages like Rust or Python, the guidance aligns with industry trends toward safer coding practices.

2. Phishing-Resistant MFA:

The updated MFA recommendations, particularly for OT products, reflect the evolving threat landscape. Phishing-resistant MFA, such as FIDO2-based solutions, provides a higher level of security by eliminating reliance on passwords. This is especially crucial for critical infrastructure, where a single breach can have catastrophic consequences.

3. Timely Vulnerability Disclosure:

The guidance’s call for timely publication of CVEs with CWEs underscores the importance of transparency in cybersecurity. Delayed disclosure can leave systems exposed to known threats, increasing the risk of exploitation. By adhering to this recommendation, manufacturers can build trust with their customers and demonstrate a commitment to security.

4. Hardcoded Credentials and Outdated Cryptography:

The inclusion of hardcoded credentials and outdated cryptographic functions as bad practices addresses two common yet dangerous oversights. Hardcoded credentials are a favorite target for attackers, while outdated cryptography can render even the most secure systems vulnerable. Manufacturers must prioritize the removal of hardcoded credentials and the adoption of modern cryptographic standards.

5. Operational Technology (OT) Considerations:

The guidance’s focus on OT products is particularly noteworthy. Unlike traditional IT systems, OT systems often have longer lifecycles and are more challenging to update. By providing specific recommendations for OT, the guidance acknowledges the unique challenges faced by this sector and offers practical solutions.

6. Secure-by-Design Principles:

The overarching theme of the guidance is the adoption of secure-by-design principles. This approach shifts the responsibility for security from the end-user to the manufacturer, ensuring that products are inherently secure from the outset. By embracing these principles, manufacturers can reduce the burden on customers and minimize the risk of breaches.

Conclusion

The updated Product Security Bad Practices guidance is a timely and essential resource for software manufacturers. By addressing common vulnerabilities and providing actionable recommendations, it empowers manufacturers to build more secure products and protect critical infrastructure from cyber threats. As the threat landscape continues to evolve, adherence to these guidelines will be crucial in safeguarding the digital ecosystem. Manufacturers who prioritize security today will not only protect their customers but also gain a competitive edge in an increasingly security-conscious market.
