Do you have an "always on" Internet connection? It's easy to think that no one could possibly be interested in your personal computer, but that's simply not the case. Having a fast Internet connection that's "always on" when you want to surf the Web is great for you, but it's also great for hackers from around the world who sweep through thousands of random IP addresses looking for computers that they can exploit. And what they can do is really quite scary.

Every computer on a network has a unique identifier. Just as you would address a letter to send in the mail, computers use the unique identifier to send data to specific computers on a network. Most networks today, including all computers on the Internet, use the TCP/IP protocol as the standard for how to communicate on the network.

All buildings on the UIC campus are connected to the UIC-Net campus backbone network, which connects computers and LANs at UIC to each other, to the Internet (via a 155 Mbps connection at the Ameritech Chicago NAP), and to the Internet2 Abilene and vBNS research networks. Most offices on campus and all dorm rooms have a 10 Mbps Ethernet or better connection to UIC-Net.

This page has instructions on how to configure Mac OS for use with the UIC-Net campus wired network. If your Mac is in a campus office or lab and it does not have an assigned IP address, you can use DHCP to set it up. If you don't know whether or not you're supposed to use DHCP, try it. If it works, then you can use it.

ACCC scanned all of its internal networks to look for hosts running a vulnerable version of the openSSL software. We identified approximately 25 machines with vulnerable versions of the software and immediately patched the software.

Although patching the systems resolves the immediate vulnerability, we will be updating private keys and installing new certs on all of the affected systems in the next few days.
