Automation Solution: Testing Data Models

If your automation solution relies on a back-end database with strict database schema you can stop reading… but if you (like most others) still live in the land of text files encoded in your favorite presentation format (because it’s hip to hate YAML), you might appreciate the solution Donald Johnson uses to check his data models before committing them into Git repository.

ISPs Should Strongly Consider MANRS to Fight Cybercrime: World Economic Forum Report

A World Economic Forum (WEF) report released today recommends that Internet Service Providers (ISPs) should strongly consider joining the Mutually Agreed Norms for Routing Security (MANRS) initiative to improve the security of the Internet’s global routing system.

Systemic security issues about how traffic is routed on the Internet make it a relatively easy target for criminals. MANRS helps reduce the most common routing threats and increase efficiency and transparency among ISPs on peering relationships.

The WEF Centre for Cybersecurity identifies four actionable principles as effective in preventing malicious activities from getting “down the pipes” from network providers to consumers in the report Cybercrime Prevention: Principles for Internet Service Providers, released today in Davos, Switzerland.

The principles were developed and tested over a year with leading ISPs around the world and multilateral organizations, including BT, Deutsche Telekom, Du Telecom, Europol, Global Cyber Alliance, Korea Telecom, Proximus, Saudi Telcom, Singtel, Telstra, and ITU, WEF says in a press release.

One of the principles is to “take action to shore up the security of routing and signalling to reinforce effective defence against attacks”, and MANRS, a global initiative supported by the Internet Society, is one of the recommendations to achieve the principle Continue reading

Cisco issues firewall, SD-WAN security warnings

Amongst Cisco’s dump of 27 security advisories today only one was rated as critical – a vulnerability in its Firepower firewall system that could let an attacker bypass authentication and execute arbitrary actions with administrative privileges on a particular device.The Firepower Management Center (FMC) vulnerability – which was rated at 9.8 out of 10 – comes from improper handling of Lightweight Directory Access Protocol (LDAP) authentication responses from an external authentication server. With it, an attacker could exploit the vulnerability by sending crafted HTTP requests to an affected device and gain administrative access to its web-based management interface.To read this article in full, please click here

VMware targets SD-WAN management with Nyansa acquisition

VMware says it plans to acquire AI-based network management and analytics firm Nyansa for an undisclosed amount.VMware said the Nyansa technology will be targeted at boosting monitoring and troubleshooting for LAN/WAN deployments within its SD-WAN package – VMware SD-WAN by VeloCloud. More about SD-WAN: How to buy SD-WAN technology: Key questions to consider when selecting a supplier • How to pick an off-site data-backup method •  SD-Branch: What it is and why you’ll need it • What are the options for security SD-WAN? Founded in 2013, Nyansa’s primary technology is a cloud-based network management package called Voyance that employs AI to automate the discovery of devices on the network and identify unusual behavior.  Nyansa says it’s being used to watch-over some 20 million client devices operating across roughly 200 networks. Its customers include Tesla, Uber, Lululemon, GE Healthcare and Stanford University.To read this article in full, please click here

Survey: Digital transformation can reveal network weaknesses

Digital transformation is a catch-all phrase that describes the process of using technology to modernize or even revolutionize how services are delivered to customers. Not only technology but also people and processes commonly undergo fundamental changes for the ultimate goal of significantly improving business performance.Such transformations have become so mainstream that IDC estimated that 40% of all technology spending now goes toward digital transformation projects, with enterprises spending in excess of $2 trillion on their efforts through 2019.To read this article in full, please click here

VMware Acquires Nyansa for AI-Aided Networking Analytics

VMware has been on a buying jag in the past year, and its latest planned acquisition is the Palo Alto, Calif.-based Sanjay Uppal said in the acquisition announcement. CEO and co-founder blog post: First, Nyansa can proactively predict client problems, optimize their network, better enable the behavior of critical IoT devices, and justify infrastructure changes based on actual user, network and application data. Second, you will be able to use the breadth and depth of Nyansa’s data ingestion and analysis, including packet analysis and metrics via API across multivendor wired and wireless LAN environments. Finally, the combination of Nyansa’s AI/ML capabilities with VMware’s existing analytics, visibility and remediation capabilities will make it easier for you to operate and troubleshoot the virtual cloud network and accelerate the realization of a self-healing network. Nyansa was valued at around $65 million after its most recent funding two years ago and had raised about $26.5 million, Carbon Black. The transaction is expected to close within the next few months, subject to customary closing conditions. VMware is a sponsor of The New Stack. Feature image

Dyndns and Openvpn – Remote Management

I have visited my home and was doing some hobby IT setup with Raspberry Pi’s, the problem is that i had problems many times accessing my home PC is another Remote Location due to many reasons, lets say crappy ISP. I contacted my ISP and they said I need to take a static IP and also pay for opening up two non standard ports. Its like you pay to get tortured and then additional headache of Port forwarding.

To add more to the pain, the IP that i get from my upstream provider is a Private IP, wow I havent seen that for a while. Anyways, to get around this I was thinking about using OPENVPN as a solution along with Dyndns.

Now, setup is very simple

Clint-pc (Location 1) ———-AWS(OPENVPN)————Client-pc (Location 2)

Why AWS -> Accessible and Cost

Problem is changing IP, I dont have any business requirement or criticality to buy a Elastic IP , but whole point will be lost if my clients wont know what to access, worse I will never have access to location-2 if am in location-1 to change IP Addresses

I have mapped OPENVPN with dyndns script.

Faster builds in Docker Compose 1.25.1 thanks to BuildKit Support

One of the most requested features for the docker-compose tool is definitely support for building using Buildkit which is an alternative builder with great capabilities, like caching, concurrency and ability to use custom BuildKit front-ends just to mention a few… Ahhh with a nice blue output! And the good news is that Docker Compose 1.25.1 – that was just released early January – includes BuildKit support!

BuildKit support for Docker Compose is actually achieved by redirecting the docker-compose build to the Docker CLI with a limited feature set.

Enabling Buildkit build

To enable this, we have to align some stars.

First, it requires that the Docker CLI binary present in your PATH:

$ which
docker/usr/local/bin/docker

Second, docker-compose has to be run with the environment variable COMPOSE_DOCKER_CLI_BUILD set to 1 like in:

$ COMPOSE_DOCKER_CLI_BUILD=1 docker-compose build

This instruction tells docker-compose to use the Docker CLI when executing a build. You should see the same build output, but starting with the experimental warning.

As docker-compose passes its environment variables to the Docker CLI, we can also tell the CLI to use BuildKit instead of the default builder. To accomplish that, we can execute this:

$ COMPOSE_DOCKER_CLI_BUILD=1 DOCKER_BUILDKIT=1 docker-compose build
