Elasticsearch Vulnerability: How to Remediate the most recent Issues

An Elastic Security Advisory (ESA) is a notice from Elastic to its users of a new Elasticsearch vulnerability. The vendor assigns both a CVE and an ESA identifier to each advisory along with a summary and remediation details. When Elastic receives an issue, they evaluate it and, if the vendor decides it is a vulnerability, work to fix it before releasing a remediation in a timeframe that matches the severity.

Machine learning log analysis and why you need it

Your log analysis solution works through millions of lines of logs, which makes implementing a machine learning solution essential. Organizations are turning to machine learning log alerts as a replacement or enhancement of their traditional threshold alerts. As service uptime becomes a key differentiator, threshold alerts are only as good as your ability to foresee an issue.

Strategically Managing Cloud Resources for Security, Fun, and Profit

The first time I created a cloud compute instance, then still called a “Cloud VM”, was an almost transcendent moment. It was like magic. I was at my first organization which had adopted the cloud, in my first DevOps position, and I immediately knew that the world had changed.

The Cloud Network Security Gap

Before we dive into the gap in cloud network security, let’s take a step back. If you’ve been in Operations for a while, you might remember how it used to be. “Network” was a team. When you needed to open a port on the network, you had to provide an exhaustive definition of the change, explaining what port you needed, what external addresses should be able to reach it, and where it should be routed to internally.

How to switch Cortex from chunks to blocks storage (and why you won't look back)

If you’ve been following the blog updates on the development of Cortex – the long-term distributed storage for Prometheus – you surely noticed the recent release of Cortex 1.4, which focuses on making support for “blocks engine” production-ready. Marco Pracucci has already written about the blocks support in Cortex, how it reduces operational complexity for running Prometheus at massive scale, and why Grafana Labs has invested in all of that work.

Secure Your Endpoints with Trend Micro & Logz.io

Trend Micro Cloud One is a strong enterprise data security solution for data centers and cloud environments. Trend Micro’s advantages, like most other security tools, lie in its pairing with other security resources. That’s where Logz.io comes in. It brings together disparate data that Trend Micro tracks to create fully summarized dashboards and extremely detailed ones with specific focuses.

10 Developer Horror Stories To Keep You Up at Night

We software engineers like to think ourselves unflappable. Consider that we spend most of our days staring at glowing pages of eldritch horror that no mortal was meant to witness. We whisper and type our otherworldly incantations, all the while feeling the hungry gaze of a lurking cross-site scripting bug, or a shadowy use-after-free, or an accidental summoning of ZALGO. (H̨e̛ ̕c͢om͢es, you know.)

Improve Elasticsearch Query Performance with Profiling and Slow Logs

If our end users end up too long for a query to return results due to Elasticsearch query performance issues, it can often lead to frustration. Slow queries can affect the search performance of an ecommerce site or a Business Intelligence dashboard – either way, this could lead to negative business consequences. So it’s important to know how to monitor the speed of search queries, diagnose and debug to improve search performance.
