File Sharing – Not Just a Geek Problem

December 5, 2009 by varidion Leave a Comment

An alarming trend has been indentified by our Partner, Palo Alto Networks, in their Applications Usage and Risks Report:  browser based file sharing has overtaken the use of client specific Peer 2 Peer applications for the first time.P2P -v- Browser

So what?

Well its simple, if today you detect and remove the use of file-sharing software within your business by managing and removing applications loaded onto your PCs, then this method is now redundant.  That is, unless you plan to remove browsers from your PCs?

Browser-based file sharing applications are a direct avenue for the transfer of confidential data and allows user download of infected files and malware-infested advertising.

The remedy is simple; you need to identify and control your applications at the network layer.  By their very nature, P2P, Malware and many Web2.0 applications masquerade as valid web and SSL traffic by hiding within their ports and protocols.  So unless your firewall can identify these rogue applications you have no way of controlling them.  Can your firewall distinguish between valid http and file-sharing http?

At Varidion, our Next Generation Firewall can identify and classify some 900 applications so control and protection is simple.  If you still managing by port & protocol speak to us about a free trial of our service, we will even give you a report outlining all the applications in use on your network.  I guarantee we’ll find something you don’t like!

Banning access to Social Networking from the corporate network is futile

October 22, 2009 by varidion 2 Comments

Monday at Gartner Symposium in Florida, Carol Rozwell, of Gartner gave some wise words:

“Banning access to social media from the corporate network is futile.”

Carol is correct, we can’t stop social networking, you only have to look at the largest firewall installed, China!   They have failed to manage the flow of incoming information via Web 2.0 sites.  Today’s world we live in is digitally enabled and socially connected.  Moreover, the enterprise cannot protect its self from everything, they must learn to balance risk and performance, cloud and software as a service has great value, but they will introduce a change in how technology is managed and controlled.  Web 2.0, SaaS and Internet based social networking applications to carry real threats to corporations and must be managed effectively with today’s tools that understand these tools…

Statefull Inspection Swiss Cheese – What’s the Point of your Firewall?

Todays Firewalls

I’m sorry to tell you, its got more holes than a Swiss Cheese! Don’t be alarmed…..      most have.

Why?   They’re just simply out of date….

Basically today’s Web 2.0 applications have technology leapfrogged your security infrastructure, so while you diligently close ports and protocols these Net Generation applications choose another port, or better still masquerade as a valid protocol such as HTTPS so your firewall hasn’t a clue. Worried? You should be.

To restore the firewall as the core of your security infrastructure you need to look deeper into the traffic that’s flowing through it, something yesterday’s firewalls simply don’t and can’t do, that was until Nir Zuk one of the inventors of Statefull Inspection Technology headed back to the drawing board…. The outcome, a truly application aware security device that can accurately identify and classify over 900 of the today’s most dynamic applications irrespective of port, protocol but crucially evasion tactic. So finally the Enterprise can adopt Web 2.0 collaboration tools with the piece of mind they can actually control them.

Today, many Enterprises block applications such as Webex, LogMeIn, Yoics and P2P applications for very obvious reasons, again I have bad news, they are in use, you just can’t see them as they look just like valid http and http/s traffic. The facts are stark, in a recent application usage report of 60 large enterprises representing the behavior of 900,000 users, Peer 2 Peer applications were found in 92% of the enterprises, and web based file sharing in 72% of the companies and guess what; 100% had Firewalls and a further 82% had additional devices such as a Proxy, URL filter or an IPS.

Now that’s a great investment! Upgrade your business today speak to Varidion about an application aware network.
