Getting Started with Lyft Envoy for Microservices Resilience

This is a guest repost by Flynn at datawireio on Envoy, a Layer 7 communications bus, used throughout Lyft's service-oriented architecture.

Using microservices to solve real-world problems always involves more than simply writing the code. You need to test your services. You need to figure out how to do continuous deployment. You need to work out clean, elegant, resilient ways for them to talk to each other.

A really interesting tool that can help with the “talk to each other” bit is Lyft’s Envoy: “an open source edge and service proxy, from the developers at Lyft.” (If you’re interested in more details about Envoy, Matt Klein gave a great talk at the 2017 Microservices Practitioner Summit.)

Envoy Overview

It might feel odd to see us call out something that identifies itself as a proxy – after all, there are a ton of proxies out there, and the 800-pound gorillas are NGINX and HAProxy, right? Here’s some of what’s interesting about Envoy:

  • It can proxy any TCP protocol.
  • It can do SSL. Either direction.
  • It makes HTTP/2 a first class citizen, and can translate between HTTP/2 and HTTP/1.1 (either direction).
  • It has good flexibility around discovery and Continue reading

Cisco warns of NetFlow appliance vulnerability

Cisco today issued a security warning about a potential vulnerability in its NetFlow traffic monitoring device that could cause the system to lock-up. +More on Network World: Cisco tries to squash Smart Install security abuse+ Specifically, Cisco wrote: “A vulnerability in the Stream Control Transmission Protocol (SCTP) decoder of the Cisco NetFlow Generation Appliance (NGA) could allow an unauthenticated, remote attacker to cause the device to hang or unexpectedly reload, causing a denial of service (DoS) condition. The vulnerability is due to incomplete validation of SCTP packets being monitored on the NGA data ports. An attacker could exploit this vulnerability by sending malformed SCTP packets on a network that is monitored by an NGA data port. SCTP packets addressed to the IP address of the NGA itself will not trigger this vulnerability. An exploit could allow the attacker to cause the appliance to become unresponsive or reload, causing a DoS condition. User interaction could be needed to recover the device using the reboot command from the CLI.”To read this article in full or to leave a comment, please click here

IDG Contributor Network: SD-WAN facilitates security on the WAN

With RSA San Francisco—one of, if not the biggest security show of the year—behind us, it’s a good time to revisit security and SD-WANs. I know, we already lived through Yoda’s prognostications about the future of networking and security. In that blog post, we spoke about vendor approaches to securing the new Internet connections created by SD-WAN. There’s another dimension, though, to SD-WAN security that we didn’t discuss and that’s about the WAN.The WAN: Risk and reward for today’s attackers For a lot of SD-WAN vendors, security integration means inspecting incoming and outgoing Internet traffic. But while services, such as Zscaler, may inspect HTTP traffic bound for the internet, they do nothing for traffic bound to other locations. And that’s a problem because increasingly site-to-site traffic requires its own inspection and protection.To read this article in full or to leave a comment, please click here

Worth Reading: How to bury a breach notification

Amid the hustle and bustle of the RSA Security Conference in San Francisco last week, researchers at RSA released a startling report that received very little press coverage relative to its overall importance. The report detailed a malware campaign that piggybacked on a popular piece of software used by system administrators at some of the nation’s largest companies. Incredibly, the report did not name the affected software, and the vendor in question has apparently chosen to bury its breach disclosure. This post is an attempt to remedy that. —Krebs on Security

IDG Contributor Network: To improve information security, enterprises and government must share information

Information security is forever weaved into our daily lives. From the massive data breaches impacting Target, Yahoo and Anthem to IoT-powered DDoS attacks that take down substantial portions of the internet for extended periods of time, information security impacts everyone.The reality is providing protection in this kind of environment is so challenging that no single entity, whether it’s a company or a government agency, can accomplish this task alone. There needs to be some kind of cooperation between the private and public sectors. This leads to the questions of what kind of relationship should the government and companies have, how can they work together and what’s preventing this process from happening?To read this article in full or to leave a comment, please click here

IT experience can be beneficial for a cybersecurity career

Given my interest in cybersecurity skills and training, I’m contacted by academic institutions, professional organizations and training companies with news about some type of cybersecurity education curriculum. This isn’t surprising given the global shortage of cybersecurity skills. In fact, new ESG research discloses that 45% of organizations report a “problematic shortage” of cybersecurity skills in 2017.Clearly we need more smart and well-prepared people to enter the cybersecurity ranks, but it’s important to note that most cybersecurity professionals don’t enter the workforce directly from college or training programs. According to research conducted in 2016 by ESG and the Information Systems Security Association (ISSA), 78% of cybersecurity professionals follow a more indirect route. These folks start their careers as IT professionals and make their way into cybersecurity as their careers progress.To read this article in full or to leave a comment, please click here

Robots are just as plagued by security vulnerabilities as IoT devices

An analysis of robots used in homes, businesses and industrial installations has revealed many of the same basic weaknesses that are common in IoT devices, raising questions about security implications for human safety.The robotics industry has already seen significant growth in recent years and will only further accelerate. Robots are  expected to serve in many roles, from assisting people in homes, stores and medical facilities, to manufacturing things in factories and even handling security and law enforcement tasks."When you think of robots as computers with arms, legs, or wheels, they become kinetic IoT devices that, if hacked, can pose new serious threats we have never encountered before," researchers from cybersecurity consultancy firm IOActive said in a new report.To read this article in full or to leave a comment, please click here

Introducing Ansible Tower 3.1

Ansible Tower 3.1

We're excited to announce the release of Ansible Tower 3.1. Our engineering team has been hard at work on enhancing Ansible Tower to allow teams to harness the power of automation across servers, applications, environments, and networks, and with Ansible Tower 3.1, we've brought together a variety of enhancements that allow your teams to automate more processes, more frequently, and more easily analyze the results of your automation across the enterprise

Model complex processes with multi-Playbook workflows

Ansible brought simple, agentless automation to IT. But some IT processes don't lend themselves to being automated in a single Playbook - if you're provisioning environments, you may want to handle basic provisioning, default configuration, and application deployment differently. And once you've automated those tasks, you want to reuse those tasks in different ways, or in different environments. Plus, what if a deployment goes wrong? You may need to back your environment out to the last known good state.

To solve these issues, we developed Tower workflows. With Tower workflows, you can chain together any number of Playbooks together into a workflow, with each workflow step potentially using a different Playbook, inventory, set of credentials, and more. Easily launch one or more Continue reading
