Ensuring firmware and software patches are regularly applied to embedded devices is crucial for maintaining their security. Embedded systems often run on specialized operating systems and firmware that can have vulnerabilities just like any other software. Regular updates ensure that any known vulnerabilities are addressed as soon is possible, reducing the risk window where attackers can exploit them. Disabling unnecessary services and ports is a common security practice but not as impactful as patching known vulnerabilities which can be exploited remotely even on necessary ports and services. Restricting physical access is important but would not protect against remote digital threats. While changing default vendor passwords is a fundamental security step, it must be assumed that these passwords have already been changed in any secure installation, and so it would not be the most effective ongoing measure.
