What is the difference between software and firmware

There are various types of software. Firmware is a special type of software that is specifically designed to handle hardware or electronic devices. What is Firmware — Definition, Functionality 2. What is Software — Definition, Functionality 3. Firmware is a special type of software. It can be in any engineering-based product, computing peripheral or consumer appliances. It is used to monitor, manage, and control data of various appliances. One example is the washing machine — it functions according to the firmware embedded into it.

Another example is TV remote, which consists of an electronic circuit and has preprogrammed firmware. These devices function according to firmware embedded into them.

Firmware-based systems get input from the user. Then they process that data and finally provide the output. The output can be thermal, electromagnetic, kinetic, etc. Usually, updating firmware is difficult. Different components may be developed and manufactured by a variety of providers and then packaged by a single vendor.

This has an impact on the need to conduct adequate supply chain risk management. The differences between hardware, software, and firmware are important for patching and vulnerability management. As a physical component, hardware vulnerabilities are difficult to remediate without complete replacement, though some can be mitigated through firmware updates. In the past, firmware was difficult to update as it typically resided on read-only memory.

While updates are now more common, they have a relatively high risk of impacting functionality, so manufacturers are reluctant to provide them frequently. Software vulnerabilities are typically the easiest to remediate, traditionally through regular security updates.

Software vulnerabilities remain the primary vector cyber threat actors use to exploit systems, making the software the most important system component to monitor and update with routine and ad hoc security patches. Lastly, vendor end-of-support impacts hardware, software, and firmware differently. In some cases, end-of-support software may become unusable due to other dependencies, whereas end-of-support firmware will likely continue to operate as designed.

Even after vulnerabilities are identified, the vendor will not issue a security notice or patch, but physical and software mitigations are sometimes available to secure end-of-support software and firmware.

Meanwhile, as hardware approaches end-of-support, replacement parts have limited availability. For all components, support or troubleshooting is no longer provided at end-of-support. Firmware file size tends to be much smaller than software as it does not contain much in the way of data needed for graphics or user interface.
