5 Cybersecurity Tips for Broadcasting (B&C)

[svg-table-content]

Here’s another example of the blurring boundaries between “enterprise IT” functions and broadcast engineering: Security. Not so long ago, the IT side of the typical TV broadcaster handled Internet-facing security necessities, like email and firewalls, while the engineering side shored up distribution-related security, usually over dedicated links. Those links were plumbed in Internet Protocol (IP) but didn’t traverse the “big Internet,” so they were, in essence, cordoned off.

These days, securing the attack surfaces of broadcast and media providers is necessarily a collaboration between IT and engineering, increasingly buttressed by top-down mandates to do whatever it takes to keep the bad guys off the digital premises. Just ask TV5Monde, in France, which suffered a massive hack in April of 2015 that took down 12 of its 12 channels overnight. Like so many hacks, the bad guys had gained entry a few months earlier, maneuvering in the background to find the weak spots.
