Teaching the Government to be Secure

This week I'm teaching a Unix and Linux security class for DISA, the Defense Intelligence Systems Agency. It's conventional, for some reason, to badmouth this Agency, but they have some incredibly smart people. As one friend said, "the longer you stand next to them, the dumber you feel".

So far we've covered the Unix basics and an overview of security. We spent this morning talking about TCP/IP security, a difficult subject to cover in a single morning, but Bob Cromwell, the course author, has done a great job of keeping the material at a high level but including useful references for those who want to understand in greater depth.

The new laptop is slowly getting fit to travel, though the DISA network doesn't seem to be as cooperative as it was the last time I was here, and that could be something to do with Internet settings. Certainly everything looks to be satisfactory. Not a matter needing urgent attention.

Those "Where Was That Disk Again" Blues

Moving information from one laptop computer to the next is a slow and painful operation when dozens of applications have to be carried forward, each with its data complete. I'll have to be more careful next time and not drop the laptop on the floor. I'm just happy the disk survived.

If only life weren't so complicated.

As the Sun Slowly Sinks in the West...

Back at AJ's for a quick goodbye, not as joyous as anticipated due to family circumstances. But good to see the Fardellas again.

The class seemed to go well, and the students appeared satisfied when they left. We shall see in a couple of weeks what they really thought, felt and knew about TCP/IP.

Now back to Dulles on a red-eye via Atlanta, benefiting yet again from the JoysOfBusinessTravel.
