This article reports that manufacturers of purpose-built digital video recorders (DVRs) are able to customize the Linux operating system code, which lets them include only the functionality, or services that customers need record and review video. Because the Linux source code is open, product engineers can access the operating system code. With only the essential services being performed, the operating system is not constantly executing unnecessary application code. Customization impacts the security of the DVR as well. By removing extraneous code, potential security vulnerabilities are eliminated.
