Cisco Released SIO iPhone Application today

I admit I'm an IPhone app junky. I surf iTunes daily for my next fix. I gave the new Cisco SIO IPhone app a spin today. SIO stands for "Security Information On-the-Go" If you are a security professional or someone who keeps up with latest alerts this is an app you would want to consider. As for me i like the security blog and Cisco field notices of the app.

Cisco SIO To Go iPhone Features

Powered by the Cisco Security IntelliShield Alert Manager Service, the Cisco SIO To Go iPhone application informs, protects and enables users to respond in real time to alerts and threats to the network. The application delivers early warning intelligence, threat vulnerability and proven Cisco mitigation solutions to users' iPhones as they occur. It also provides unique IP and URL address e-mail and Web reputation look-up powered by the Cisco IronPort® SenderBase Security Network and the Cisco SIO.

Alerts delivered include:

Cisco Product Security Incident Response Team (PSIRT) Alerts

Cisco Intrusion Prevention Systems (IPS) Signatures

Cisco Applied Mitigation Bulletins

Cisco Threat Outbreak Alerts

And many others

Nov072009 File Sharing at its best (IPhone app included!)

Recently I was introduced to Dropbox file sharing. I am that shiny object kind of guy and dropped what I was doing to investigate Dropbox (Thanks Brandon, lol). First, I found the ease of uploading and file management so much better than other file share apps. I was also impressed with how easy it is to share public files and how to manage those files or folders. The kicker and deal closer for me, yup the IPhone app just drove this out of the park. You can d/l the Dropbox app and you have full access to ALL your files and better yet, from the Dropbox IPhone app you can share and invite others to share your folders. So if you’re a busy engineer or just a file freak  in general this app is for you. I see myself migrating to this more then my FTP.

Dropbox give you 2 gig free. You can purchase 50 gig @ $10 a month and 100 gig @ $20 a month. Well worth the investment!


Mental Case & for your IPod Touch or IPhone

I can’t tell you how much time I devote to study. The hours are countless and the nights are long. If you are in the technology field you know my pain. I needed to find a way to maximize my study efforts and more importantly repetition of the details so that I would have them ingrained into my brain.

I was recently introduced to a Mental Case ( ), no no it’s not your girlfriends ex-husband or some stalker girl you dated, it’s a software program that runs on your IPOD Touch or IPhone.

Mental Case allows you download customizable flash decks from Flash Card Exchange, ( There are thousands of slide decks currently being shared on Flash Card Exchange. What is really cool, for a small fee you can create your own Flash Decks which you can download to your POD. You can also share your deck with the world if you like.

Currently, there is a pretty wide selection of Cisco and some CWNP decks available. But again, create your own decks and study exactly what you need to! I would also warn you if you choose to use someone else’s flash deck make sure there answers are correct! LOL
