BrandPost: SD-WANs Enable Scalable Local Internet Breakout but Pose Security Risk

SD-WAN streamlines how application traffic is routed from the branch, making it easier to create local internet breakout and allowing users to access cloud services directly from the branch. In an ideal SD-WAN scenario, every remote location and device has its own local internet breakout and corresponding security services. Yet, reality looks a lot different for many companies. This is something network professionals have wanted to enable for decades. The problem was that setting up local internet breakout using traditional routers was not trivial and required a tremendous amount of engineering work so most businesses, except for the ones that had high levels of technical talent shied away. The shift to cloud and edge computing has made local internet breakout almost mandatory today, so businesses have turned to SD-WAN as a simpler path to enable it. As this happens, organizations need to understand the security risks. To read this article in full, please click here

Security Policy as Code Now Fully Automated with Calico Enterprise 2.6

We are excited to announce the general availability of Calico Enterprise 2.6 (formerly known as Tigera Secure). With this release, it is now possible to fully-automate Security-Policy-as-Code within a CI-CD pipeline, including the ability to implement security as a Canary rollout, which is the most critical requirement to automating network security.

DevOps is now mainstream and practiced in nearly every major enterprise; it has transitioned from what was a competitive differentiator a few years ago to the industry standard today.

DevOps relies on automation to continuously optimize the cycle time from code to production. DevOps automation manifests itself in 2 forms.

  1. Automation of the underlying infrastructure (infrastructure as code)
  2. Automation of the software delivery process (Continuous Integration and Continuous Delivery (CICD) pipeline)

Security has become an integral part of the DevOps team’s responsibilities. A quick sample of DevOps jobs on LinkedIn is a quick example; nearly every DevOps job posting has “security” as a required responsibility. It’s no longer enough to automate the infrastructure, it is now necessary to implement security within the delivery pipeline and perhaps link SW CI-CD pipelines with the corresponding security policies that they should be deployed with. DevOps teams have struggled to automate this Continue reading

Test coverage of Python packages in Cisco NSO

In most of the Python projects I’m working with Pytest is used to test the code, and Coverage is used to check what lines that the tests validate. For this to work, Coverage must take part in the execution of the Python code. While this isn’t a problem for most projects working with NSO poses a challenge since the actual Python code for each NSO package gets executed in a separate Python virtual machine. The goal of this article is to show you how you can overcome this obstacle and gain some insight into your test coverage for your NSO Python packages. Continue reading

The Linux who command tells who’s logged in and a lot more

Did you ever wonder who is logged into a Linux system but not know how to find out? This two-minute tip can solve the problem with an introduction to the who command in this 2-minute Linux Tip by Network World blogger Sandra Henry-Stocker.The who command can tell you who is logged in to the network, count them and give a list of them on a single line. It can also show when a system was last booted as well as the run state that the system is in.For those who don’t want to use the formal commands for the various who functions, it’s possible to create aliases that are more intuitive than the commands as written for Linux.To read this article in full, please click here

Fortinet CEO: Network and security technologies give rise to security-driven networking

The network and security industries both continue to evolve at a rate never seen before.  Historically, security and network operation teams have worked in parallel with one another, sometimes being at odds with each other's goals.However, that is changing as businesses rely on their networks to operate. It’s fair to say that today, for many companies, the network is the business. As this happens, network and security technologies need to be more closely aligned giving rise to the concept of security-driven networking.[Get regularly scheduled insights by signing up for Network World newsletters.] In this post, ZK Research had a chance to sit down with the co-founder and CEO of Fortinet Ken Xie to discuss the future of networking and security. To read this article in full, please click here
