The recent Heartbleed scare brought SSL to the fore. But what is it and why is management of SSL traffic so important?

The recent Heartbleed vulnerability in SSL received significant media coverage. But what exactly is SSL? And why does your business need to think about how to manage SSL web traffic? CBR picked the brains of Charles Sweeney, CEO, Bloxx, to find out.

In simple terms, SSL creates a secure tunnel for Web traffic to be transmitted between the Web browser on an endpoint and a Web server.

This tunnel ensures that communication remains secure and prevents unauthorised eavesdropping of the information being sent and received. The simplicity of SSL has made it the de facto choice for secure Web-based transactions such as ecommerce sites and online banking. SSL traffic has grown dramatically and in some sectors, SSL traffic now accounts for 75% of overall Web traffic.

With the implementation of SSL now extending to other applications such as Web mail, what do you need to know to ensure that it remains a 'secure line' for your business? Charles Sweeney, CEO, Bloxx offers his top five considerations:

1. It's not enough to assume that because the traffic is encrypted it is harmless. In many organisations, SSL traffic passes freely in and out of the network, yet not all traffic encrypted with SSL is benign. The content maybe inappropriate or contain malware threats that could harm an organisation's network and endpoint devices, impact user productivity or see a company fall victim to a cyber attack.
