President Obama’s high-security BlackBerry used a special process known as “whitelisting” that only allowed it to take calls and messages from pre-approved contacts, two former senior intelligence officials with knowledge of the set-up told Fox News – pointing to the detail as further proof the White House knew Hillary Clinton’s private account was used for government business.
As the administration now acknowledges, Obama and Clinton emailed each other while she was helming the State Department. If received on his BlackBerry, the “whitelisting” safeguard means Clinton and other contacts would have had to be approved as secure for data transmission – covering everything from emails to texts to phone calls. The Obama BlackBerry would have also been configured to accept the communications.
“Think of whitelisting like a bouncer in the VIP line at the party. If you are on the list you get in, if you are not, you get bounced to the pavement,” said Bob Gourley, former chief technology officer (CTO) for the DIA, and now a partner with strategic consulting and engineering firm Cognitio.
“Whitelisting happens by design. The IT professionals who whitelist devices at places like the White House only add the email addresses authorized by management. To do otherwise would be to violate policy in ways that could introduce threats to the system,” he added.
