Useful documentation sheets at packetlife.net

Packetlife.net offers some “cheat sheets” with useful information. This are like very small handbooks with the most useful informations about BGP, EIGRP, IPsec, Multicast, IS-IS, OSPF, Spanning-Three, TCPdump and more. I found this very useful during my preparations for Cisco exams and not only, so I want to share them here. Of course any copyrights goes to the owner of packetlife.net. And if you are worry about the “cheat” word, look what the owner of packetlife.net is saying:

“Are these for cheating?

No. The term “cheat sheet” is a slang term for a small collection of notes or a quick reference guide (my apologies if this isn’t a familiar term in your locale). I don’t condone cheating of any sort, and you’re only doing yourself a disservice if you decide to take that path.”

New DOS attacks threaten wireless data networks

Forget spam, viruses, worms, malware and phishing. These threats are apparently old school when compared to a new class of denial-of-service (DOS) attacks that threaten wireless data networks.

The latest wireless network threats were outlined in a talk here Thursday by Krishan Sabnani, vice president of networking research at Bell Labs, at the Cyber Infrastructure Protection Conference at City College of New York.

Sabnani said the latest wireless data network threats are the result of inherent weaknesses in Mobile IP, a protocol that uses tunneling and complex network triangulation to allow mobile devices to move freely from one network to another.

“We need to especially monitor the mobile networks – with limited bandwidth and terminal battery—for DOS attacks,” Sabnani said.

Here are five wireless data network threats outlined by Sabnani:

1. Signaling DOS

2. Battery Drain

3. Peer-to-Peer Applications

4. Malfunctioning Air Card

5. Excessive Port Scanning
