Time for an Upgrade
This summer, Scout and I are upgrading the Diagnostics facilities to include some new equipment and make more room for our experiments.
Just like how you have to regularly update your software to defend it from attack, we need to update Diagnostics to stay on top of the latest computing issues. That way, we'll be better equipped to deal with an attack. Scout is so excited about getting his upgraded Repair and Recovery room that he's been furiously tidying up everything in sight in preparation. Less work for me!

Cyber Defense Threats: Packet Sniffers
A packet sniffer is a device or program that spies on data traveling between networked computers. All information sent across a network travels in small chunks of data, called "packets." The packet sniffer can capture and copy these packets and save them for someone to analyze later.
Packet sniffers can be used in helpful ways, like to watch for problems on the network or gain information about a network intrusion, but they can also be used in criminal ways, like to spy on other network users and collect sensitive information such as passwords.
Packet sniffers run in the background collecting data but don’t actually send any data out, so they can be very hard to detect. If they can’t understand the data they will just throw it out, so the best way to protect yourself from a packet sniffer is to make sure you use "encryption" when you send sensitive data, which will use a secret code to protect it.

How Computers Work: What are Device Drivers?
A device driver is a software program that controls a device attached to your computer. It acts as a translator for the operating system, converting the operating system's instructions into messages that the device can understand.
Some devices that use drivers are contained inside your computer, like the graphics card and the sound card, and others are peripherals, like mice and digital cameras. A new computer usually comes with the latest drivers already installed.
When you install new devices or new software on your computer, sometimes you have to update the device driver to make sure the device or program works properly. You can usually download the latest drivers from either the computer manufacturer's Web site or the device manufacturer's site.
