Gregory D. Johnsen:

This is John Brennan's story, his life and his career. But it's also ours. The excesses and mistakes of more than a decade of war, what we tolerate and what we don't. What we're willing to forgive and what we won't. Politicians who don't deliver on their promises, and well-intentioned individuals who bring about great harm. It's about the man he is, and the country we've become.

Violet Blue:

DHS is out of step, out of touch, and so arrogant and ambivalent with a keynote like Johnson's that it's actually surprising at the end of the day that they can't even try to fool us into believing that cybersecurity isn't just another thing they have to pretend to understand until they retire.

DoD:

We are vulnerable in this wired world. Today our reliance on the confidentiality, availability, and integrity of data stands in stark contrast to the inadequacy of our cybersecurity.

Amit Yoran:

I don't think security breaches are stoppable in the current computing paradigm.

Michael Schmidt:

Inside the White House, the intrusion has raised a new debate about whether it is possible to protect a president's electronic presence, especially when it reaches out from behind the presumably secure firewalls of the executive branch.

John Leyden:

Embedded Packet Capture (EPC) was designed by Cisco as a troubleshooting and tracing tool. The feature allows network administrators to capture data packets flowing through a Cisco router. Brazilian security researchers Joaquim Espinhara and Rafael Silva were able to abuse the feature and build a system to hoover up massive volumes of data.

Niels Provos:

Had the entire web already moved to encrypted traffic via TLS, such an injection attack would not have been possible. This provides further motivation for transitioning the web to encrypted and integrity-protected communication.

Alex Stamos:

These days, network security has to be pushed into the end nodes ...

Morgan Marquis-Boire:

The big take-away is that cleartext is just dead.
