Protecting myself on a College Network

"What is the best way to protect yourself at college on a college network? I am going to have a NAS, set up there too and what is the best way to protect as much as possible? Unfortunately, my college does not allow routers, so that is out." -- David Bruns

Why are they doing this?

1. They need to control the devices on their network
2. They need to NOT have rogue WiFi APs that congest the airwaves
3. They need to know WHO has done something unauthorized on their network

How are they doing this?

1. Scanning for WiFi APs (even hidden ones) -- Possibly running deauth attacks on any non-auth AP
2. Most likely, they're also looking at MAC addresses to see if he's using a device registered from a router manufacturer.
3. Traffic Inspection: If a single IP (through a NAT) has more active connections than can be expected from a single device, they can escalate your connection to an "inspect the room" search

So... we have two challenges:

1. Don't let them DETECT that you're using a router.
2. Don't let them SEE that you're using a router.

Basic precautions:

1. Turn off the Wi-Fi
2. Close ALL the ports
3. No external acccess of your NAS
4. Limit multi-device throughput

Advanced Precautions:

Cloning your MAC address

What is geocaching, how to find them, and why it's fun to go exploring for them!

Physical geocaches often consist of:

• Waterproof container
• Log book w/ pen or pencil
• Trade items or trackables

There are now over 2.8 million geocaches in over 180 countries...plus GC1BE91 on the International Space Station.

About the items in the cache:

• They are NOT "prizes" unless otherwise specified
• When trading items, trade equal or up
• Don't leave food because it attracts animals

Trackables move from cache to cache

• Only take one if you know what to do with it. Some have specific goals.
• Can be tracked at Geocaching.com

Seeking a Geocache

Handy stuff to have...

• GPS (or smart phone with app)
• water
• flashlight
• spare phone battery
• gloves
• hand wipes
• hat & sunscreen
• comfortable shoes
• long pants (to avoid prickly or poisonous plants)

When seeking a cache...

• Watch out for muggles!
• Don't be too suspicious when seeking a cache.
• Participate in CITO (Cache In, Trash Out)

Find the OFFICIAL TWiT GEOCACHE!

• Located at N 38° 16.607' W 122° 40.001'
