In September, a critical bug in the open source Bourne-Again Shell (BASH) that’s ubiquitous in Unix-based systems, including Linux and Mac OS X, displaced Heartbleed as the top network security threat. Called Shellshock, the bug allows hackers to insert code into the shell and hijack an operating system through the internet. From there, they can access sensitive information—unless a strong defense is in place.

As we found out in our recent survey, network security and data security are the two most challenging security functions to migrate to cloud environments. Specifically, the problems highlighted in survey respondents include:
Exciting news from AlgoSec this week: we announced our solution for unified security policy management across hybrid cloud infrastructure. This is a key component of our “managing security at the speed of business” vision and supports our mission to automate security policy management in evolving data centers and networks.
Following on from his recent Security Management 201 video which provides some key tips to help you easily define, simplify and enforce network segmentation and security zoning, Professor Wool has now produced a new video on how to structure your security policy in a segmented network.
