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.

What I'm doing about Contact Tracing apps during the global pandemic

The short answer is, I'm using the COVID Alert NJ [1] [2] app on my smartphone.  I find it to be a safe, secure, and private way for me to participate in helping to stop the spread of COVID-19.  That being said, I didn't trust the app blindly.  I did research and testing to ensure it met my requirements for privacy and security.  My findings are below in case it helps you make a choice on whether or not you participate as well.  For more

In the upcoming months IAS will be making a change to the login process for our web based applications by adding support for Duo Multi-Factor Authentication (MFA).  This is the same technology that we currently use for our remote access system, OpenVPN.  This move will change the look of the login screen, which we explain below.

Zoom Meeting Security

Now that we've moved our meetings to being online, there are some safety concerns that we need to keep in mind that we never had to think too hard about before.  We are seeing news articles about "Zoom-bombing", where uninvited guests join public Zoom calls to disrupt, or even terrorize its participants.  There are a number of techniques that you can use to secure your Zoom sessions.

Be Aware of Gift Card Scams and other Phishing Attacks

What are Gift Card Scams?

The story starts with an innocent email from a supervisor, colleague, or friend asking for your help.  They tell you a tale about how they need some gift cards for gifts to family, friends, potential donors, etc.  Unfortunately, they are unable to make the purchase themselves, could you help them out?  And of course, it is an emergency, please do it as quickly as possible.  Did you just fall for a gift card scam?

Spotting a scam email (aka a phish)


We are inundated with information nowadays, from the tweets, texts, TV, streaming, email, mentions, etc, etc.  This hectic lifestyle puts us into a mode of needing to respond as soon as possible to any interruption or notice that happens in our lives.  The problem is, malicious scam artists are aware that we are overwhelmed by the influx and are taking advantage of our vulnerability.  They do this by creating realistic looking emails and enticing us to click on them and enter our sensitive data before we realize it is a scam.
