A settings screen for Harbour View, a twenty-four-room seaside hotel, checked against its secure baseline: default passwords changed, updates and encryption on and old staff accounts removed, while the cameras' remote access is still on its wide-open default and guest wifi has drifted from the baseline for convenience.
