8 private automation hub features about automation execution environments

Red Hat Ansible Automation Platform 2.1 introduced automation execution environments, which is a new way to package automation into a container runtime environment. In addition, private automation hub also joined the party by adding significant support for execution environments. 

Let's dive into those features:

 

Feature 1 - The registry

Private automation hub now ships with the pulp container registry. This means it can store and serve up container images. 

We only support the Ansible private automation hub registry serving execution environment images.

 

Feature 2 - Remote registries

The Ansible private automation hub user interface allows the administrator to define remote registries. This allows for the registry to mirror container images from their source. A good example of remote registries is adding the base execution environment images available at Red Hat.

To access the Red Hat registry, visit registry.redhat.io and use the same username and password that you use for access.redhat.com.

 

Upon adding the registry, you will see a new remote registry definition.

 

Feature 3 - Indexing a remote registry

This capability is available after you have added a remote registry as per Feature 2;click the menu on the registry Continue reading

In Ukraine and beyond, what it takes to keep vulnerable groups online

This post is also available in 日本語, Deutsch, Français, Español, Português.

As we celebrate the eighth anniversary of Project Galileo, we want to provide a view into the type of cyber attacks experienced by organizations protected under the project. In a year full of new challenges for so many, we hope that analysis of attacks against these vulnerable groups provides researchers, civil society, and targeted organizations with insight into how to better protect those working in these spaces.

For this blog, we want to focus on attacks we have seen against organizations in Ukraine, including significant growth in DDoS attack activity after the start of the conflict. Within the related Radar dashboard, we do a deep dive into attack trends against Project Galileo participants in a range of areas including human rights, journalism, and community led non-profits.

To read the whole report, visit the Project Galileo 8th anniversary Radar Dashboard.

Understanding the Data

• For this dashboard, we analyzed data from July 1, 2021 to May 5, 2022 from 1,900 organizations from around the world that are protected under the project.
• For DDoS attacks, we classify this as traffic that we have determined is part of a Continue reading

Cisco DNA Upgrade Issues – Application Update Stuck

After initiating Cisco DNA Appliance version 2.1.2.4 and starting an upgrade towards 2.2.2.8 in order to get to 2.2.3.5 I got a strange issue where the appliance system update went fine but the switch to 2.2.2.8 was disabled until Application Updates did not finish. The real issue here was that Application Updates of Cloud Connectivity – Data Hub got stuck on 12% for 4 days without timing out or finishing. Tried several appliance reboots from CIMC which didn’t help. Below are the steps that helped sort out Application Updates issues with container pods being stuck at the point of pooling

What is Wireshark?

Wireshark is a popular, free and open-source packet capture tool that enables network and security administrators to take a “deep dive” analysis into traffic moving through a network.Wireshark can be deployed for a variety of purposes including sniffing out security issues, troubleshooting network performance problems, traffic optimization, or as part of the application development and testing process.What Does Wireshark Do? Wireshark is primarily used to capture packets of data moving through a network. The tool allows users to put network interface controllers (NICs) into promiscuous mode to observe most traffic, even unicast traffic, which is not sent to a controller’s MAC address. However, doing this normally requires superuser permissions and may be restricted on some networks.To read this article in full, please click here

Select the Best Switching ASIC For the Job

Last week I described some of the data center switching ASIC design tradeoffs and the ASIC families Broadcom created to fit somewhere in that multi-dimensional space.

Next step: how could you design your data center fabric to make the most out of them? To keep things simple, we’ll build a typical leaf-and-spine fabric with a WAN edge layer (sometimes called border leaf switches).

How to manage scripts that manage network automation

Most major network outages happen as a result of human error, not equipment failures—mistakes in the settings themselves, missed steps in a sequence, steps taken out of order, etc. Automation through scripting is meant not only to speed up network operations activities but, as importantly, to reduce the chance of such mistakes by ensuring consistency. A script executes the same steps, in the same order, every time.Ad-hoc, scripting, or programmatic automation doesn’t eliminate the possibility of error, of course. It does limit the scope of the mistakes to the programs themselves, and robust testing should uncover most of them before they have a chance to be put into production. And, should a mistake get through and result in a bunch of misconfigured switches, there is one place to fix it—the script—that also provides the means of correcting the problem at machine speeds.To read this article in full, please click here

What’s new in Calico Enterprise 3.14: WAF, Calico CNI on AKS, and support for RKE2

At Tigera, we strive to innovate at every opportunity thrown at us and deliver what you need! We have listened to what users ask and today we are excited to announce the early preview of Calico Enterprise 3.14. From new capabilities to product supportability and extending partnerships with our trusted partners, let’s take a look at some of the new features in this release.

Web application firewall (WAF)

Web applications are a critical aspect of any business, whether they are public facing or internal. There has been a fundamental shift in the way these applications are developed—as they have become more container-based and API-based, we refer to these as cloud-native applications.

To keep these modern web applications secure, we need to analyze all HTTP communication and block any malicious traffic traversing the web application. However, in a cloud-native environment, we can’t achieve this using simple network policies or by using perimeter network firewalls. Instead, a cloud-native web application firewall (WAF) would be necessary.

This is why we have introduced a cloud-native WAF into Calico Enterprise that’s different from the traditional WAFs you may know. While most traditional WAFs are deployed Continue reading

Let’s celebrate the 8th anniversary of Project Galileo!

This post is also available in 日本語, Deutsch, Français, Español and Português.

We started Project Galileo in 2014 with the simple idea that organizations that work in vulnerable yet essential areas of human rights and democracy building should not be taken down because of cyber attacks. In the past eight years, this idea has grown to more than just keeping them secure from a DDoS attack, but also how to foster collaboration with civil society to offer more tools and support to these groups. In March 2022, after the war in Ukraine started, we saw an increase in applications to Project Galileo by 177%.

Read ahead for details on all of our eighth anniversary announcements:

• Two new civil society partners helping choose participants
• New insights on attack patterns using data from Cloudflare Radar
• A portal designed to ease onboarding for Galileo participants
• Details on our sessions at RightsCon this week
• New case studies highlighting Galileo participants and the important work they are doing

Announcing two new Project Galileo partners

This year, we are excited to welcome two new partners, International Media Support and CyberPeace Institute. As we introduce new partners, we are able to expand the project Continue reading
