If portions of enterprise data-center networks have no need to communicate directly with the internet, then why do we configure routers so every system on the network winds up with internet access by default?Part of the reason is that many enterprises use an internet perimeter firewall performing port address translation (PAT) with a default policy that allows access the internet, a solution that leaves open a possible path by which attackers can breach security.+Also on Network World: IPv6 deployment guide; What is edge computing and how it’s changing the network?+To read this article in full, please click here(Insider Story)

IPv6 has been gaining traction since it was developed in the late 1990s, and enterprises that are implementing it now are considered to be among the early majority – meaning widespread adoption is well underway – so if you haven’t already begun, you need to start planning IPv6 deployment.To read this article in full or to leave a comment, please click here(Insider Story)

‘Tis the season for tech bloggers to prognosticate and pontificate about the trends for the next year. This is also the time of year when we fondly reflect on the amazing rate of innovation during the past year and try to imagine how the pace of new technology will continue to accelerate. When publicly making these types of predictions, it is prudent to write about trends that are probable, and it is unwise to write about things that are too far-reaching. Along these lines, here are six network and security technology predictions that are probable for 2017.1. Malware will continue to evolve
Malware has been the most effective way for attackers to reach targets globally. Malware propagation has been the definitive attack method for the past few years, and now the effectiveness of most antivirus products is called into question. More and more security vendors offer malware defenses, but not all of these vendor’s solutions are completely effective as malware continues to metamorphize.To read this article in full or to leave a comment, please click here
Recently, one of our neighbors sold their home and they had a Google Nest thermostat. This became an issue during the sale process. The prospective buyers wanted the Nest to remain, but current owners wanted to take it with them.To read this article in full or to leave a comment, please click here(Insider Story)
Do you remember when we used multi-protocol routing for IPX, AppleTalk, and TCP/IP running on the same network? In the 1980s and early 1990s many enterprises had multiple protocols running on the physical network infrastructure as “ships in the night”. Cisco routers became highly adept at multi-protocol routing and the company grew in prominence as a result. Then in the early 1990s, TCP/IP won out and the internet took shape as the global network we enjoy today.To read this article in full or to leave a comment, please click here(Insider Story)

The enterprise WAN has transitioned from dedicated TDM circuits with Frame Relay and ATM, to Packet-over-SONET and MPLS, and now to Ethernet-access services. However, two things have remained constant, WAN bandwidth is still expensive and provisioning WAN services can take a long time.To read this article in full or to leave a comment, please click here(Insider Story)
Many people anticipated that enterprise organizations would adopt Software Defined Network (SDN) technologies later than service providers or multi-tenant data centers and cloud service providers. We are now seeing more use of Network Functions Virtualization (NFV) within enterprises and some enterprises are starting SDN pilot projects. As enterprises consider how to utilize SDN technologies in their data center environments, they start to consider what new security capabilities SDN can provide. SDN switches can drop packets for flows that are not permitted by the controller. This article explores if SDN switches can behave like a traditional firewall.To read this article in full or to leave a comment, please click here
