Security for Devices Hardware and Operating System Software<\/p>\n
The software and hardware used for embedded devices can include built-in security functionality. Some of the most commonly enabled hardware security features include secure boot, attestation, cryptographic processing, random-number generation, secure key storage, physical tamper monitoring, and JTAG protection. To fully leverage the hardware features, operating system software requires device drivers specific to the architecture of the underlying processor.<\/p>\n
Operating system software can also come with built-in security functionality. The VxWorks RTOS includes built-in security features for secure boot (digital signed images), secure ELF loader for digitally signed applications, secure storage for encrypted containers and full disk encryption, kernel hardening, and much more. (See the VxWorks datasheet for a full list.)<\/p>\n
The Linux operating system also provides a number of security packages developers can use to help secure their OS platform build. Wind River Linux, a commercially provided Yocto Projectbased build system, includes more than 250 verified and validated security packages. The Linux operating system can also be hardened to provide anti-tamper and cybersecurity capabilities.<\/p>\n
