Welcome to the Network Security website at the IAS
This website is intended to bring you the latest news, how to's, tools and resources in Information Security. Security Awareness of our Faculty, Members and Staff is key in creating a safer computing environment.
The three major Principles of Information Security, Availability, Integrity and Confidentiality, will be covered throughout the security awareness program at the Institute. For a description of these principles, please see our About section.
In keeping with the spirit of the Institute, I encourage questions and open discussions about security. And if you discover anything out of the ordinary, please feel free to bring it to my attention so that we can work together to create a more productive, safer environment.
Thanks,
Brian Epstein <security@ias.edu>

Aww man, it's us
As a security professional, I spend a lot of my time making sure that the bad guys aren't able to break in. I set up all the fancy firewalls and anti-virus to keep us safe. But what happens when a user unknowingly gives up their credentials due to a phish? Well, if you are lucky, the spammers just use it to spam the world. If you are unlucky, the figure out how to attack the inside of your network to get to the crown jewels.

My last post on Ransomware was in 2013 when we were being hit by Cryptolocker. I mentioned that in around 2010 Data Doctor 2010 was the ransomware in the news. According to Wikipedia, the first "ransomware" was called the "AIDS Trojan" in 1989, which didn't encrypt your files, but merely hid their data by encrypting the filenames.
