You have to wonder if they had a breach at some point and this is the result.

A bank where I consulted required frequent password changes. Users would have so many they had used they would write them down.

Post-it on the monitor.
Under the keyboard
In the drawer
And the smartest ones - A post-it on the bottom of the drawer.

Better than 90% find rate in less than 30 seconds.

Didn't help if someone wanted to hack into the system, but anyone that had access to the desk... and some were in customer open areas.

Talking to management about it was like talking to a three year old. Absolutely no comprehension of what we were trying to convey. Someone told me once that one of the upper managers had a teenage boy work on his home computer and he was told by him to do this. He was too stupid to realize that kid is still laughing at him.

The man who owned a company I worked for for 22 years made a major software decision based on talking with someone on a plane.

Switch from Windows XP to Windows NT for all AutoCAD computers. It was an expensive, time consuming, disaster. We weren't allowed to test. Just put it on all AutoCAD computers. Now.

We're talking a few hundred computers, a **** pot full of down time, troubleshooting from Hell, and then removing the NT versions and going back to XP. A few hundred copies of NT sitting in the back room that were not ever going to be used.

And he did not learn from it. He came back from some show in Chicago and started in again. The thing is the man was not stupid. He just acted like he was sometimes.

Too many people have no concept of security.

When I started my current job, the elevators ran from 7:30 - 5:30. Our receptionist works from 8:30 - 5.
So the office was basically open to ANYONE from 730-830 and 5-530.
They saw nothing wrong with this. "Well I don't want to deal with an elevator fob all the time!"
Yea.. too bad.

One of those ignorant questions.
My router is supplied by Comcast .Can I change password? Do I need to?
I just looked up properties and it's set to private with no sharing of any kind allowed
Memory (laughable word) tells me when setting up, there was a supposedly safe, split way to be a hot spot for other Comcast users, which I declined.

It is a good question. Your "supplied" router's default password is on the bottom of the router. While this is better than the generic password used by some companies, it isn't completely secure (since it is possible the passwords used by comcast follow a pattern).

I will leave further answers to others here.

Yep most are easy to break.. for a while they setup with admin and last 4 digit of the mac address. btw is easy to find when your sniffing.

i would change it if it was me. ( im in network security job market, so its natural for me)
