Consul/HAProxy vs VulcanD/EtcD

HAProxy + Consul vs VulcanD + EtcD

HAProxy/Consul

  • Pro: Both are production ready
  • Pro: Can handle any throughput we will see
  • Pro: More feature rich
    1. Healthchecks
    2. DNS and HTTP API available to map endpoints
    3. Lots of service discovery built in
  • Pro: Solution could be used in more than one place (bld/prod/etc..)

TOTP secrets leaked to Google via charts API

TL;DR

When implementing 2FA it's a bad idea to generate the QR image containing the TOTP secret using Google charts:

<img src="https://chart.googleapis.com/
          chart?chl=otpauth%3A%2F%2Ftotp%2F...secret%3Dacl...mwv&amp;chs=200x200&amp;cht=qr" />

Paranoid mode: ON

Google tracks all your internet moves and could easily exploit this vulnerability to bypass 2FA:

A SaltStack AWS Auto Scaling Solution

A SaltStack AWS Auto Scaling Solution

Overview

The AWS Auto Scaling Goup, configured with a customised Cloud-Init file, sends a notification to an SNS Topic, which in turn passes it onto an SQS queue that the Salt Master is subscribed to. A Reactor watches for the auto scaling events and pre-approves the new minion based on its Auto Scaling group name and instance ID.
