Many Enterprises Still Struggling With Remote Security, Cisco Study Finds
This article by Tim Wilson discusses the results of Cisco’s latest survey results, showing that while many organizations appreciate the increased employee productivity and other benefits offered by laptop computers, smartphones, and virtual private networks, they may not have established clear security strategies or plans for employees to work remotely. Companies said they had enabled an average of 63 percent of employees with laptops, and another 46 percent of employees are using smartphones. Of the companies that have adopted mobility and remote-access technology, 62 percent said doing so had resulted in increased employee productivity, with 57 percent noting an increase in employee satisfaction and 42 percent seeing a reduction in overhead costs. But only 27 percent of the enterprises surveyed had enabled more than half of their workforce to work remotely. This study shows us that companies need to be rethinking remote access.

With flu season in full force, employees need a quick and easy way to access the network in case of an emergency.

Best Way to Stop Malware from Spreading in a Large secure Network
This blog post answers the following question: What’s the best way to stop malware from spreading in a large secure network with no internet connectivity and a multi-platform environment? For a host setting, some suggestions they included were a firewall, remote device management and file integrity monitoring. For a network based situation, they suggest using IPS on the network, segmenting your network with firewalls and using anomaly detection tools.  In a hybrid situation, they recommend using an agent-less scanning tool and Network Access Control (NAC) because you could have all the security in the world until the stranger sitting next to you plugs in his laptop to the Ethernet port.
