Icinga Director v1.7.0

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. ;-)

Open Data nutzen

#^Open Data nutzen: Wie der Refugee Datathon Zahlen zum Thema Asyl verarbeitet - Linux Magazin
Politisch aufgeladene Diskussionen wie die ums Asyl brauchen belastbare Zahlen. Dank des Informationsfreiheitsgesetzes sind diese direkt bei den Behörden erhältlich. Die liefern allerdings oft nur schlecht geeignete Formate. Gefragt sind dann Tools, um sie aufzubereiten.

Wer Zahlenmaterial aus verschiedenen Quellen, verschieden formatiert und mit verschiedenen Größenordnungen verarbeiten muss, braucht die richtige Technik. Dieser Beitrag stellt einen bewährten Ansatz vor und nutzt als Beispiel ein Projekt, zu dem sich 2015 eine Gruppe von Menschen aus der IT zusammenfand, um öffentliche Daten zum Thema Asyl einzufordern und sichtbar zu machen: der Refugee Datathon Munich.
Die Gruppe trifft sich seitdem regelmäßig in ihrer Freizeit, um zu einem Fakten-basierten Verständnis der Flüchtlingssituation beizutragen. Die Autorin dieses Artikels gehört dieser Gruppe an. Wie sieht der Weg von den Behördendaten bis zum Erkenntnisgewinn aus?

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.

Shared Protection By Matthias Wübbeling
The Malware Information Sharing Platform lets you record and document security incidents – and share the information with users on other networks.
Cunning attackers often collaborate with others and share information about vulnerabilities. Companies, on the other hand, face hackers as lone warriors and all too often rely on traditional security technologies. But companies can also share IT security knowledge. One platform for sharing security information is the Malware Information Sharing Platform (MISP).

monitor the progress of data through a pipe

 Thu, 22 Jun 2017 23:48:49 +0200 
This is a really nice tool I didn't knew something like that exists. How many times I was wondering how the progress of loading a sqldump was.

man pv
pv shows the progress of data through a pipeline by giving information such as time elapsed, percentage completed (with progress bar), current throughput rate, total data transferred, and ETA.
To use it, insert it in a pipeline between two processes, with the appropriate options.  Its standard input will be passed through to its standard output and progress will be shown on standard error.

When you have a space-intended file and you want tabs. Will create one tab for 4 spaces and only at the beginning of a line.

Business Process module

 Fri, 27 Jan 2017 18:01:25 +0100 
There is a lot of progress compared to the old BPM.

Business Process module v2.0.0 released
Want to visualize part of your IT infrastructure in a hierarchical way? Do you know the Business Impact of single services? What would happen in case you power down a specific server? Would it have any influence on your most important services? If yes, which applications would have been affected? This is what the Icinga Business Process module has been built for.

Define as many processes nested as deep as you want: each node can calculate it’s own state based on a given logical operator. Show them as a tree or using the tile renderer. Discover the business impact of your components, simulate state changes and deploy Icinga Service Checks and Notifications. Start to monitor whole processes instead of single services.

#^Automated Malware Analysis - Cuckoo Sandbox
What is it? In three words, Cuckoo Sandbox is a malware analysis system.

In other words, you can throw any suspicious file at it and in a matter of seconds Cuckoo will provide you back some detailed results outlining what such file did when executed inside an isolated environment.

Malware is the swiss-army knife of cybercriminals and any other adversary to your corporation or organization.

In these evolving times, detecting and removing malware artifacts is not enough: it's vitally important to understand how they operate in order to understand the context, the motivations and the goals of a breach, for better protecting in the future

Cuckoo Sandbox is a free software that automated the task of analyzing any malicious file under Windows, OS X, Linux, and Android.
