Birds-eye view of Kubernetes objects

 Kuberenetes has given a 'Software view' for the 'hardware' world. That too all resources consumed via modern definitions using json/yaml and via API. 

Kuberentes segments the compute resources into Worker nodes & Master Node(s) and contain persistent entities called 'Kubernetes Objects' including

  • Containerised applications
  • Cluster and Associated nodes
  • Resources to these nodes
  • The policies and tolerances on how the applications interact and behave

Below is a good diagram of the various components



Each component can be defined by software/code and scalable which makes kubernetes the de-facto building framework for modern micro-service applications. 

In most of the scenarios the components can be tiered into 

  • Host/Virtual machines
  • Kuberentes Platform
  • Containers
  • Microservices

It is hence very important to understand the difference between traditional 2 tier model and kuberentes 4 tier model for all your Operational, Security and Observability needs for a successful implementation.

Elastic Beats on pfSense : Installation and configuration

Summary Though in many cases syslog is preferred to transport the pfSense logs to external system, Elastic beats provides quite a niche way to send the logs while modelling the data alongside. This makes it ready-made to send to ElasticSearch directly and get ready-made outcomes like SIEM, performance etc. Pre-reqs A build server (preferably Ubuntu or Fedora) with internet connectivity shell access to pfsense server Basic knowledge of Elastic Stack (filebeat.yml configurations etc) Ensure connectivity is allowed from pfsense machine to your Elastic Stack receiver Setup Summary Connectivity tests Install dependencies in build server (vagrant, virtualbox, gmake, go etc) Download Elastic Beats source Make elastic Beats package for FreeBSD Copy binary packages to pfsense server Configure Beats to send to destination Configure ElasticSearch to view the data Installation Steps Connectivity tests Logon to pfsense server via Shel

Syslog Standards: A simple Comparison between RFC3164 & RFC5424

Syslog Standards: A simple Comparison between RFC3164 (old format) & RFC5424 (new format) Though syslog standards have been for quite long time, lot of people still doesn't understand the formats in detail. The original standard document is quite lengthy to read and purpose of this article is to explain with examples Some of things you might need to understand The RFC standards can be used in any syslog daemon (syslog-ng, rsyslog etc.) Always try to capture the data in these standards. Especially when you have log aggregation like Splunk or Elastic, these templates are built-in which makes your life simple. Syslog can work with both UDP & TCP  Link to the documents the original BSD format ( RFC3164 ) the “new” format ( RFC5424 ) RFC3164 (the old format) RFC3164 originated from combining multiple implementations (Year 2001)
