Hacking a Terror Network: The Silent Threat of Covert Channels

Jeremy pressed the small white button just outside the door and waited patiently. He had the clearance required to enter the area, but his badge hadn t been added to the system yet. It just meant that he had to wait until someone came and let him in not too much of an issue. He heard the sound of the lock click from the inside and the door swung open and the face of a woman appeared. She looked as if she was in her mid-40s and had likely been working in the government for some time. Her clothes were professional, yet casual by most standards. Yes, can I help you?
Hi, he answered back with a smile. My name is Jeremy, and I came down to meet with Tyler. He s expecting me.
She looked at his badge, checking the clearance level indicated on the badge. Smiling she replied back to Jeremy, Come on in; I ll take you to his desk.
Thanks! He followed closely behind her as they crossed the short distance to Tyler s cubical. As he walked behind her, his eyes were drawn to the hardware lying haphazardly around the office.
Tyler? she asked as she stuck her head just inside his space.
Oh, hi, Janis, Jeremy heard Tyler reply. What s up?
There is someone here to see you, she said. Jeremy.
Excellent, come on in, Jeremy. Thanks Janis. I didn t hear the door bell. Jeremy saw Tyler smile at Janis as he entered the small cube.
