"Logging" In to a chroot
At this point, you'll be able to access the chroot with a command such as $ chroot /chroot/ bash, which will chroot you into the /chroot/ directory and execute bash from within it.
As I mentioned, chroot is not an inherently secure method for isolating applications. By not logging into the chroot as a privileged user such as root, and by removing any setuid and setgid binaries that run with elevated privileges, you can ensure that nothing runs as root within the chroot environment:
# find / -type f -perm +6000
Sandboxing is now easier than ever and its benefits have never been more important. Isolating badly written web applications from the underlying operating system or letting an administrator install a program without affecting the system can save both time and money. Like anything, prevention and foresight can significantly reduce the amount of work needed to maintain and fix a system long term, and sandboxing offers a practical tool to accomplish this.
