Description: The firmware lifecycle refers to the stages that firmware goes through from development to implementation and eventual retirement. This process includes several critical phases, starting with planning and design, where requirements are defined and the firmware architecture is established. Next, coding takes place, where developers write the code that will bring the firmware to life. Once this phase is complete, thorough testing is conducted to ensure that the firmware functions correctly and meets quality and security standards. Implementation is the next stage, where the firmware is loaded onto the corresponding device, such as an embedded system, IoT sensor, or smart appliance. Subsequently, maintenance occurs, which includes updates and security patches to address vulnerabilities that may arise over time. Finally, the lifecycle culminates in the retirement of the firmware, which can happen when the device becomes obsolete or is replaced by a new version. This cycle is fundamental in the context of cybersecurity, as outdated firmware can be a vector for attack, highlighting the importance of properly managing each stage of the lifecycle to ensure the integrity and security of connected devices.
