What Is Zero Trust Network Access (ZTNA)?

In the first article in this series, we discussed what zero trust security is and why it matters. In this article, we will take a deep dive into zero trust network access, how it works, and its benefits to the modern organization.   What Is Zero Trust Network Access? Zero Trust Network Access, or ZTNA, is a security solution that many IT departments and IT organizations use to ensure secure remote access to a range of data, applications, networks, and services within an organization. ZTNA is based on defined access control policies that clearly communicate who has access to what and for how long that access is granted. ZTNA is a gap-filler when it comes to secure remote access tools, methods, and technologies. VPNs or virtual private networks are different from zero trust network access because VPNs give access to an entire network rather than specific applications or data. As the remote workforce continues to take shape and many companies lean on it as a source of employee satisfaction and employer productivity. Zero trust network access is pertinent to keeping the right people in and the wrong people out of your organization’s systems. How Does Zero Trust Network Access Work Continue reading

Cloudflare Relay Worker

Cloudflare Relay Worker
Cloudflare Relay Worker

Our Notification Center offers first class support for a variety of popular services (a list of which are available here). However, even with such extensive support, you may use a tool that isn’t on that list. In that case, it is possible to leverage Cloudflare Workers in combination with a generic webhook to deliver notifications to any service that accepts webhooks.

Today, we are excited to announce that we are open sourcing a Cloudflare Worker that will make it as easy as possible for you to transform our generic webhook response into any format you require. Here’s how to do it.

For this example, we are going to write a Cloudflare Worker that takes a generic webhook response, transforms it into the correct format and delivers it to Rocket Chat, a popular customer service messaging platform.  When Cloudflare sends you a generic webhook, it will have the following schema, where “text” and “data” will vary depending on the alert that has fired: 

{
   "name": "Your custom webhook",
   "text": "The alert text",
   "data": {
       "some": "further",
       "info": [
           "about",
           "your",
           "alert",
           "in"
       ],
       "json": "format"
   },
   "ts": 123456789
}

Whereas Rocket Chat is looking for this format:

{
   "text": "Example  Continue reading

WEBINAR: ISP Design – Separation of Network Functions


Recently, we recorded a webinar to explain a design concept frequently used by iparchitechs.com to build and migrate WISP, FISP and Telco networks – separation of network functions. It centers around simplification of roles within an ISP network. It also explores the use of lower-cost commodity network equipment to maximize the service area for a given ISP footprint while meeting key requirements like scale, redundancy and capacity.


Topics that were covered include:

  • What are network functions?
  • Design examples for WISP/FISP and Telco
  • Equipment and budget considerations



Here is an example of solving design/operational issues with network function separation:

Private 5G: Its use in enterprises faces challenges

Interest in deploying a private 5G network is growing among enterprises, but mainstream deployment faces a number of obstacles, including competition from less complicated and more widely available wireless options such as Wi-Fi 6/6E.Private 5G could be a game changer for some enterprises, particularly in the industrial, automotive, and energy sectors. A private 5G network can guarantee throughput and latency levels that next-generation use cases require, according to research firm Gartner. But it’s still very early in the private-5G game. It could take a decade for it to take hold, as 5G coverage needs to expand and costs for 5G subscription plans and capable devices need to come down.To read this article in full, please click here

Are we there yet?

This transition to IPv6 has been going on for 20 years now, and if there was any urgency that was instilled in the effort by the prospect of IPv4 address exhaustion then we’ve been living with exhaustion for a decade now. So perhaps it's time to ask the question: How much longer is this transition going to take?

BGP MPLS-VPN Option B

The Cisco documentation about this call it Inter-AS Option B with the use case being to extend LSPs between sites over the one link. As Option B is the only MPLS-VPN method supported by Cisco SD-WAN I wanted to get a better understanding of how it works aswell as see if it could be used to extend multi-VRF prefixes between edge routers and a core switch within the same AS (rather than using Option C with LDP).

Practical OpenStack #004. Build Real World Setup

Hello my friend,

Believe or not, but the vast majority of the OpenStack Certified OpenStack Administrator (COA) trainings are not touching the architecture of the OpenStack clouds. Instead, they focus solely on the operational aspect, so that the COA certified engineer can manage OpenStack cloud. We believe it is not correct, as without how something is build it is very difficult to troubleshoot something or even guarantee a decent level of performance. Hence, we show today the full scale OpenStack cluster setup, which you can build yourself in your lab, as well as hyper converged cluster, which is suitable for building of 5G far edge locations.

Practical OpenStack #003. Why these videos

Hello my friend,

OpenStack isn’t new, since the first release on 21 October 2010, the 25 releases were already published bringing new capabilities and services to OpenStack users. Moreover, these days the micro services leveraging Kubernetes and containers are the main trend for application development, whereas virtual machines going in the past. That’s true to a degree; however, the OpenStack is a perfect platform to build a normalised infrastructure for your Kubernetes, which is by the way provide some key services to Kubernetes, such as load balancing.
