10 Software Security Practices for Long-Term Resilience

Summary

An opinion article recommends 10 lasting software-security practices, including secure-by-design architecture, dependency provenance, continuous code verification, remediation of security debt, and threat modeling AI systems.

Key points

• Build security into system architecture with secure defaults, approved patterns, and clear trust boundaries.
• Maintain an updated inventory of applications, dependencies, tools, AI models, and external services, with assigned ownership.
• The author says their research found 44% of AI-generated coding tasks introduced a known vulnerability, and recommends independent security testing before code reaches production.
• Assess software components as they enter the supply chain, record provenance, detect malicious or abandoned packages, and plan safe upgrades.
• The article cites Veracode research finding security debt affects 82% of organizations and recommends sustained remediation funding and tracking unresolved risk.
• Threat-model AI agents across their identities, permissions, tools, memory, data, runtime, and network access; constrain sensitive actions and preserve evidence of agent activity.
