What Goes on During a Scientologist “Security Check?”?

Question by Steven: What goes on during a Scientologist “Security Check?”?
There’s a rumor going down amongst Scientology watchers involving a woman named Mary Rieser, the director of Narconon Georgia (a Scientologist drug rehab center that was sued for the death of a Marine Corps veteran and is now facing an insurance fraud investigation). Mary Rieser stepped down as director and rumor has it that’s she’s at a place called “Flag” (Scientology’s megachurch in Florida) and is “getting sec-checked within an inch of her life.”

After some Googling, I found out that “sec-checking” is Scientology-speak for “Security Check.”

I’m just wondering, what typically goes on during a Scientologist “Security Check?” What does getting “sec-checked” entail?
