Cisco IP Device Tracking

Ever thought about how ACS gets an end users IP or how when showing an interfaces authentication sessions it had the IP of the host attached? This all stems from IP Device Tracking. I only recently came across it when troubleshooting an issue we had with windows machines not getting a DHCP address due collision detection involving the 0.0.0.0 address. Although there are lots of posts about people having a similar issue and the workarounds, I couldn’t find much information on the exact reason why this happened. This post is designed to give more reasoning on why this happens.

Checkpoint Gateway and Mangers

Checkpoint Firewalls are not zone based Firewalls so have a different type of policy compared to ASA and Juniper. A typical build consist of a Security Gateways managed by a centralised Management Server using the Checkpoint Smart Dashboard software. Firewall policies are created and managed on the management server and pushed to the security gateway.

Cisco continues its network-based security strategy by moving to acquire Observable Networks

Over the past few years Cisco has changed the face of its security business. What was once a struggling concern is now the fastest-growing part of Cisco. How did the company do this? Part of the rebirth of Cisco security can be traced to a change in focus, away from point products to a more data-driven model. Big data, analytics and machine learning have been hot topics in IT, and Cisco has gotten religion in this area and applied it masterfully to its security business.Today, Cisco added to that when it announced its intent to acquire privately held Observable Networks. The St. Louis-based company provides dynamic network behavior monitoring to help security teams find anomalies that could indicate a breach. The product captures data and analyzes it to gain situational awareness of all users, devices and traffic, not only on a company’s network, but also out to the cloud, with support for both Amazon Web Services and Microsoft Azure.To read this article in full or to leave a comment, please click here

IBM reorgs services division around Watson and A.I.

IBM has revamped and restructured its services division to provide greater emphasis on its Watson platform and artificial intelligence.IBM has been retrenching around Watson, a series of cognitive applications and A.I. applications in one coherent platform, for the last few years as traditional sales of mainframe hardware and software continue to dry up.Bart van den Daele, general manager of IBM Global Technology Services in Europe, told Bloomberg that the new A.I.-centric services will help IBM’s customers minimize disruptions such as server outages or other malfunctions by predicting problems before they occur and taking corrective action, such as adding cloud capacity or rerouting network traffic around bottlenecks.To read this article in full or to leave a comment, please click here

Worth Reading: New German law encourages censorship

Social media companies and other hosts of third-party content will soon face potential fines of €50 million in Germany if they fail to promptly censor speech that may violate German law. Last week, the German parliament approved the NetzDG legislation, which goes into effect 1 October and will require social media sites and other hosts of user-generated content to remove “obviously illegal” speech within 24 hours of being notified of it. —Center for Democracy and Technology

Networking Challenges in OpenStack Clouds

Did you decided that is time to implement OpenStack to build your Cloud? Have you tested in the lab? Evaluated many distributions available and hired specialized OpenStack resources? However, when the environment goes into production, Neutron is not integrating with the physical network?

If the above story closely resembles what you have faced, this post will unconceal the many challenges of Networking with any OpenStack distribution and how VMware NSX is the missing piece for your Cloud.

Networking and Security Challenges with OpenStack

Since its creation, the biggest challenges of OpenStack Clouds implementations are automation, integration and orchestration of the required networking and security components at the physical infrastructure layer. The main difficulty is that these environments are extremely heterogeneous and most of the devices do not have an open and programmable interface for configuration and, thus, the initial way of running OpenStack was to pre-provisioning the network manually and only use basics functionalities when implementing security services.

With the rise of Network Virtualization solutions and evolution of Open vSwitch, some of these challenges were solved, making it possible to create an abstraction layer from the physical elements of infrastructure and automate the virtual network through the programmable interface Continue reading
