Jenkinsfile in GitLab CI

Tempting...

#^Running Jenkins Files inside GitLab CI
Learn how to lift and shift your Jenkins jobs over to GitLab CI while you migrate.

First, I want to set some ground rules for this. For starters, this process is not meant for long term use. There are many downsides to this - Such as it only runs in one GitLab Stage and isn’t asyncronous. However this process can be used to run your Jenkins builds in GitLab CI, While you’re migrating your Jenkinsfile to GitLab CI Syntax. Make no mistake - This doesn’t solve your migration woes, But it does allow you to run your Jenkinsfile inside GitLab for the time being. It’s a stop-gap measure.

Log file Navigator

#^The Log File Navigator
Image/photo

Many logging tools, like Splunk, provide great features but are optimized for large-scale deployments.  They require installing and configuring servers before they can be effectively used.  There is still a need for a robust log file analyzer for the terminal.
Just point lnav to a directory and it will take care of the rest.  File formats are automatically detected and compressed files are unpacked on the fly.
Log files are a wealth of information, lnav can help highlight the parts that are important and filter out the noise.

Modern Lifecycle Policy?

 Mon, 25 Nov 2019 15:49:26 +0100 
o_O
As a modern online service, the Microsoft Teams client auto-updates every two weeks. Because Teams is governed by the Modern Lifecycle Policy, it is expected that users remain on the most up to date version of the desktop client. This ensures that users have the latest capabilities, performance enhancements, security, and service reliability.

O_o
Users on Teams desktop clients that are more than three months old will encounter a blocking page giving the options to update now, reach out to their IT admin, or continue to Teams on the web.

:hailking

The behaviour how this software installs automatically on every computer with M$ Office365 feels a lot like malware. It installs the Micro$oft Teams desktop client on the regular office update. In addition it installs a program that will reinstall the Micro$oft Teams Desktop client on next reboot if just the client was uninstalled. :prisoner

Who will ever want to install the Micro$oft Teams client for Linux that will be released next month.

Support-Ende für Windows Server 2008 und Windows Server 2008 R2 am 14. Januar 2020: Ohne Migration riskieren Unternehmen Sicherheitsprobleme und Compliance-Verstöße
Am 14. Januar 2020 endet der erweiterte Support für Windows Server 2008 und Windows Server 2008 R2. Doch es gibt noch immer Unternehmen, die keine konkreten Pläne für die Migration auf ein neues Betriebssystem haben. Damit ab dem Stichtag keine Sicherheitslücken oder Verstöße gegen Compliance-Vorschriften zu riskieren sind, rät Microsoft zu einem Umzug der Server auf Azure. Die Migration in die Cloud gibt den Unternehmen mehr Zeit, um neue Lösungen für ihre Software-Anwendungen zu finden, die noch die Nutzung der alten Server erfordern.

Icinga Director v1.7.0

 Mon, 30 Sep 2019 11:01:42 +0200 
Finally \o/

#^Icinga Director v1.7.0 has been released
Over the last four years, the Icinga Director has grown from an optional configuration add-on to a mature Software product with lot‘s of features. Most Icinga installations are now driven by the Director, no matter whether they are small or huge, manually curated or fully automated.
But it will not stop here. Many cool ideas are eager to finally become reality. Director v1.7 is a huge step in that direction, as it lays the foundation for a completely new type of features. We are now able to delegate complex tasks to a dedicated background daemon that has been introduced with this version. New library modules have been published, allowing us to share cool bleeding edge funtionality among different modules in a more efficient way.


The first release that includes my property modifier from December last year. ;-)

#^Icinga 2.11
Now we are here, after many months of development – we proudly release Icinga 2.11 available today.

Bleeding edge
It has been an emotional ride with many changes under the hood. The most obvious change is that Icinga’s distributed cluster operates more stable, the past quirks with hanging certificate signing requests or dead-locked TLS handshakes are now gone. This required us to go an unusual route: Evaluate new libraries and programming techniques in order to replace hand-written lower layered code, with later replacing the entire code base for the network stack operations in Icinga. This is a massive effort in quality and stability where users had called out for 3.0 already.

Zentrales Logging mit dem Elastic Stack

#^Zentrales Logging mit dem Elastic Stack
on media.ccc.de

Dezentrales Logging wird mit der steigenden Zahl von zu überwachenden Prozessen immer aufwändiger. Deshalb gibt es seit mehreren Jahren Tools welche das Zentrale Logging unterstützen. In diesem Vortrag soll der Elastic Stack als ein solches Tool vorgestellt werden.

In der Welt der Microservices ist die Anzahl der Logs-produzierenden Prozesse sehr groß und liegt durchaus im Bereich von 100-1000 Prozessen. Eine manuelle Log-Verarbeitung ist hier so gut wie undenkbar. Doch auch monolithische Services laufen oftmals dezentral und das Analysieren der Produktions-Logs ist dann häufig auch mit viel Aufwand verbunden. Mithilfe eines zentralen Loggins lässt sich eine viel bessere Übersicht über den Gesamtzustand eines Systems gewinnen, da nicht jedes Log einzeln untersucht werden muss, sondern die Logs aggregiert und somit auch leicht automatisiert ausgewertet werden können. Der Elastic-Stack bietet die Möglichkeit, große Mengen an Logs zu speichern und zu durchsuchen. Das Ökosystem um den ELK-Stack unterstützt Entwickler, DevOps usw. dabei, die Logs schnell und einfach aufzubereiten, damit diese gut analysierbar sind. In diesem Vortrag werden die Vor- und Nachteile des zentralen Loggins dargelegt und gezeigt, wie sich der Elastic Stack in Umgebungen einbinden lässt.

#^SIEM on the Elastic Stack | Elastic SIEM
Security teams use Elastic SIEM to detect threats by analyzing events from network, host, and cloud technologies, as well as other data sources.

Elastic SIEM equips security practitioners with easy data ingestion via Beats, shareable analytics based on the Elastic Common Schema (ECS), and the ability to interact with security data using the #SIEM app in Kibana. As threats continue to evolve, so too will Elastic SIEM.

#^SQL is No Excuse to Avoid DevOps - ACM Queue
A friend recently said to me, "We can't do DevOps, we use a SQL database." I nearly fell off my chair. Such a statement is wrong on many levels.
"But you don't understand our situation!" he rebuffed. "DevOps means we'll be deploying new releases of our software more frequently! We can barely handle deployments now and we only do it a few times a year!"
I asked him about his current deployment process.

#^DNS-OARC 30: Bad news for DANE | APNIC Blog
For many years the Domain Name X.509 certification system, or WebPKI, has been the weak point of Internet security. By ‘weak point’ you could as easily substitute ‘festering, rancid, underbelly’ and you would still be pretty much right on the mark! The massively distributed trust system has proved to be unmanageable in terms of integrity and there is a regular flow of stories of falsely issued certificates that have been used to perform intrusion attacks, eavesdrop on users, corrupt data and many other forms of malicious behaviours.
