We have just recently added the latest in our ongoing series of videos where we put the spotlight on a particular application and dig deeper into specifically how companies are using the application, the risks that it introduces to an enterprise and how to mitigate them. This week Twitter goes on the hot seat and you may surprised what you learn.
For instance, we will cover that the “teenage” perception of Twitter is largely unfounded and why Twitter is a new favorite technology for businesses. We’ll also cover a brief history of the security challenges Twitter has experienced over the years including public battles with hackers, public battles with the FTC and all the nasty things that can happen when the President’s Twitter account gets hacked. Then of course we will dive into specifically how to mitigate these and future Twitter risks, and how security teams can safely enable Twitter for your enterprise users. Take a look, and as always, let us know what you think.

Real-time voice and video communication on the Internet is main stream today with several popular instant messengers (IMs) supporting VoIP calls. A big hurdle in the initial adoption of VoIP was the fact that most PCs or other devices sit behind firewalls and use private IP addresses. Multiple private addresses (IP address and port) in the network are mapped to a single public address by a firewall using a technique called Network Address Translation (NAT). But the end device is not aware of its public address, and hence cannot receive voice traffic from the remote party on the private address it advertises in its VoIP communication. One solution to this NAT traversal problem is a tool called Session Traversal Utilities for NAT (STUN), devised by the IETF to allow applications to discover their public address and port mappings for use in communication with a peer.
Below, I’ve tried to deconstruct a Yahoo Messenger voice call with the hope of understanding how STUN is used in NAT traversal. Read more…

I’d like to introduce everyone to one of our latest projects here at Palo Alto Networks. In short, we have released the first of a forthcoming series of brief videos, each one focusing on a particular application, its benefits, the risks it brings to the enterprise and how those risks can be properly managed.
Our first video covers the ubiquitous Facebook which you can see here.
Since this is our first of these videos, we’d love to hear what you think about it. Was it interesting and/or helpful? What other sorts of information would you like to see covered? Is there an application that you would like to see highlighted in the series? Any and all suggestions are welcome so take a look and let us know what you think.
