Post Deployment Security
Post Deployment Security is a cybersecurity methodology focused on protecting applications, systems, and infrastructure after they have been deployed into production environments. It involves continuous monitoring, vulnerability management, and incident response to detect and mitigate threats that arise during runtime. This approach complements pre-deployment security practices like secure coding and testing, ensuring ongoing protection against evolving attacks.
Developers should learn and implement Post Deployment Security to address real-world threats that emerge after applications go live, such as zero-day exploits, configuration drift, and runtime attacks. It is critical for maintaining compliance, protecting sensitive data, and ensuring business continuity in cloud-native, microservices, and DevOps environments where rapid deployments increase attack surfaces. Use cases include monitoring for anomalous behavior, applying security patches, and responding to breaches in production systems.
