NXLog - 2022 in review

We’ve come to the end of 2022, and what a year it’s been. It was a year marked by war, economic toil, and addressing the aftermath of the Covid-19 pandemic. Europe was immediately thrust into crisis in February when the Russia-Ukraine War began. Unfortunately, as an Eastern European-based company, many of our colleagues were directly affected by it. Then, more recently and in the United States especially, many tech companies began restructuring their organizations to deal with the looming economic problems that are forecast.

2023 and NXLog - a review

It’s finally the holiday season, and we’re down to a skeleton staff here at NXLog. It’s nearly time for us to shut down our laptops, pick up a cup of hot chocolate (or mulled wine if we’re lucky), and get ready for a week or so of reading, relaxing, opening presents, perhaps coping with distant relatives, and all-around merry-making over the holiday period. So we hope you’ll forgive us if we keep this recap of 2023 succinct.

The GeoServer breach that could have been stopped in hours, not weeks

How a federal agency’s monitoring gaps turned a containable incident into a three-week nightmare In September 2025, CISA responded to a federal agency breach that security teams could have stopped in hours. Instead, threat actors roamed the network undetected for three weeks. The damage? Multiple compromised servers, web shells planted across the infrastructure, and a persistent foothold that took significant resources to remediate. The root cause wasn’t a zero-day exploit or sophisticated malware.

BROP attacks - What is it and how to defend yourself?

Have you ever locked yourself out of your car? After calling for roadside service, your tow truck driver forces the internal locking mechanism open with a slim-jim. Car thieves quickly discovered this technique and began using it to steal cars. Digital thieves have devised a similar attack called a Blind Return-Oriented Programming (Blind ROP, or just BROP) attack. It’s as quiet as a jackhammer on cement, but an attacker can open a remote shell and gain remote code execution on your server if the conditions are right.

Centralized log management: What it is, how centralized logging works, and how to choose the right system

Centralized log management is the practice of collecting logs from across an environment, including applications, servers, containers, networks, and cloud services, and storing them in a single location where they can be searched and analyzed. For operations and security teams, centralized logging is now a core requirement. Without it, logs are scattered across hosts, ephemeral containers, cloud consoles, and disconnected tools. This fragmentation slows troubleshooting, complicates incident response, and limits visibility during security investigations.

The benefits of log aggregation

Logs are a record of the internal workings of a system. Nowadays, organizations can have hundreds and, more regularly, thousands of managed computers, servers, mobile devices, and applications; even refrigerators are generating logs in this Internet of Things era. The result is the production of terabytes of log data—event logs, network flow logs, and application logs, to name a few—that must be carefully sorted, analyzed, and stored. Without a log management tool, you would need to manually search through many directories of log files on each system to access and extract meaning from these millions of event logs.

Top 5 security concerns revealed with DNS logging

The Domain Name System (DNS) facilitates communication between all devices connected to the Internet. It consists of hierarchical servers that can translate any given hostname, along with its corresponding domain name, to its internet protocol (IP) address(es). One of the most common is the windows DNS server that ensures that data requests are sent to their correct endpoints while providing human-readable addresses for websites connected to the Internet. With the ever-growing number of cloud-based devices and technologies, for instance, the Internet of things (IoT), portals, web applications, as well as online transaction processing, it is more important than ever to identify the actual physical addresses of remote devices when relying on DNS-dependent connectivity.

Raijin vs Elasticsearch

Log collection is most closely linked to enterprise security practices—for example, aggregation and analysis in a SIEM. However, collecting certain logs for reasons other than security is often valuable. It may even be a requirement of your organization for the purposes of auditing, legal compliance, or data retention. Storing all these logs in a database is the most efficient way to manage the data. Finding and managing logs stored as flat files or structured data can be challenging without a database.

However, the vast volume of logs generated can lead to significant challenges, including high costs and inefficiencies. Many companies collect an excessive number of logs, often missing out on the most critical security-related events. The majority of these logs, known as log noise, offer little to no value to security analysts and can obstruct timely access to high-priority security events.

HIPAA logging requirements and how to ensure compliance

The U.S. Health Insurance Portability and Accountability Act (HIPAA) was introduced in 1996 to protect the privacy and security of health information. HIPAA’s Privacy, Security, and Breach Notification rules require healthcare providers and their partners to protect electronic protected health information (ePHI) through robust access controls, breach reporting, and documentation practices. A critical part of this compliance effort involves maintaining detailed audit logs that track who accessed, modified, or disclosed PHI, and retaining HIPAA logs for at least six years.

Identity and Access Management (IAM): Guide for 2026

Imagine a typical company: employees join, they move between offices and departments, then they leave. Each of these changes requires a systems access update for email, databases, internal tools, and more. Manually managing these transitions can be burdensome and error-prone. And where you have errors, you have inefficiencies and exposure to security breaches — neither of which is good for your business. This is where Identity and Access Management (IAM) comes in.

Leveraging Okta logs for improved security monitoring

Most corporate environments require a login, and Identity and Access Management (IAM) is a solution that helps manage that process in different ways. IAM ensures that only the necessary people can access the relevant IT resources. Each user, device or service is assigned a unique digital identity. So, when an employee logs into a company system, IAM confirms that person’s identity. This might involve a login/password check, multi-factor authentication, or both.

Watching the watchers: The need for telemetry system observability

Organizations invest heavily in sophisticated monitoring platforms, deploy countless agents across their infrastructure, and build elaborate dashboards to track every metric imaginable. Yet amid this pursuit of comprehensive visibility, a dangerous blind spot often emerges: the observability system itself becomes unobservable. This meta-problem represents one of the most insidious risks in modern infrastructure management. When telemetry collection fails silently—whether due to misconfiguration, infrastructure changes, or system failures—operations teams continue making critical decisions based on incomplete or stale data, unaware that their digital nervous system has developed gaps in coverage.

Top 5 security concerns revealed with DNS logging

The Domain Name System (DNS) facilitates communication between all devices connected to the Internet. It consists of hierarchical servers that can translate any given hostname, along with its corresponding domain name, to its internet protocol (IP) address(es). One of the most common is the windows DNS server that ensures that data requests are sent to their correct endpoints while providing human-readable addresses for websites connected to the Internet. With the ever-growing number of cloud-based devices and technologies, for instance, the Internet of things (IoT), portals, web applications, as well as online transaction processing, it is more important than ever to identify the actual physical addresses of remote devices when relying on DNS-dependent connectivity.

The benefits of log aggregation

Logs are a record of the internal workings of a system. Nowadays, organizations can have hundreds and, more regularly, thousands of managed computers, servers, mobile devices, and applications; even refrigerators are generating logs in this Internet of Things era. The result is the production of terabytes of log data—event logs, network flow logs, and application logs, to name a few—that must be carefully sorted, analyzed, and stored. Without a log management tool, you would need to manually search through many directories of log files on each system to access and extract meaning from these millions of event logs.

Telemetry is evolving; is your business ready?

Some still think telemetry is a futuristic concept, but it isn’t. It’s already integral to the smooth running of everything from websites, e-commerce platforms and mobile apps to manufacturing, traffic control and much, much more. And it all begins with the humble data log. From the earliest days of computing, programmers have recorded useful information — often in a file — to help track and react to potential threats and understand what’s going on "under the hood" of their IT infrastructures.

Watching the watchers: The need for telemetry system observability

Organizations invest heavily in sophisticated monitoring platforms, deploy countless agents across their infrastructure, and build elaborate dashboards to track every metric imaginable. Yet amid this pursuit of comprehensive visibility, a dangerous blind spot often emerges: the observability system itself becomes unobservable. This meta-problem represents one of the most insidious risks in modern infrastructure management. When telemetry collection fails silently—whether due to misconfiguration, infrastructure changes, or system failures—operations teams continue making critical decisions based on incomplete or stale data, unaware that their digital nervous system has developed gaps in coverage.

From network event logs to insights: Visualizing OpenVPN logs with Elasticsearch and Kibana

At NXLog, we help customers solve real-world telemetry data challenges and bring value to the table with NXLog Platform. One of the recurring problems we see is that while network event logs contain a wealth of information, turning them into actionable insights isn’t straightforward. Security operations teams often struggle to make sense of these logs in a way that directly supports threat detection, response, and investigation. A perfect example of this challenge is VPN logs.

Current challenges in log and telemetry data management

Today, most enterprises use a security log analytics solution or SIEM (Security Information & Event Management), but analytics are only as good as the data fed into your solution. If you’re missing data sources or are failing to extract full value from the data, you won’t see the big picture. This is an issue new customers commonly mention to NXLog. That’s why one of our key goals is to provide a solid data collection layer that ensures all relevant data is collected and properly fed into the SIEM.

Three easy ways to optimize your Windows logs - Reduce cost, network load, and time

If you are capturing Windows Event Logs on a large scale, you know that the more logs you collect, the more resources you need. Thus, the more expensive your SIEM becomes. The main issue is a large amount of the log data you are sending to your SIEM contains no valuable information. This means you waste a sizable portion of your cost on what the industry calls “log noise”.

Raijin vs Elasticsearch

Log collection is most closely linked to enterprise security practices—for example, aggregation and analysis in a SIEM. However, collecting certain logs for reasons other than security is often valuable. It may even be a requirement of your organization for the purposes of auditing, legal compliance, or data retention. Storing all these logs in a database is the most efficient way to manage the data. Finding and managing logs stored as flat files or structured data can be challenging without a database.

Identity and Access Management (IAM): Guide for 2026

Imagine a typical company: employees join, they move between offices and departments, then they leave. Each of these changes requires a systems access update for email, databases, internal tools, and more. Manually managing these transitions can be burdensome and error-prone. And where you have errors, you have inefficiencies and exposure to security breaches — neither of which is good for your business. This is where Identity and Access Management (IAM) comes in.

Leveraging Okta logs for improved security monitoring

Most corporate environments require a login, and Identity and Access Management (IAM) is a solution that helps manage that process in different ways. IAM ensures that only the necessary people can access the relevant IT resources. Each user, device or service is assigned a unique digital identity. So, when an employee logs into a company system, IAM confirms that person’s identity. This might involve a login/password check, multi-factor authentication, or both.

The CrowdStrike incident and how the NXLog agent operates

Automatic updates are recommended by many vendors as they are considered essential for safeguarding against security threats and maintaining system performance. Updates not only enhance security but also deliver bug fixes and new features, contributing to improved user experience. Software updates, however, come with the inherent risk of breaking existing functionality and can potentially interfere with other software or the operating system itself causing unintended side effects. Automatic updates that the user has no control over escalate the risk further.

BROP attacks - What is it and how to defend yourself?

Have you ever locked yourself out of your car? After calling for roadside service, your tow truck driver forces the internal locking mechanism open with a slim-jim. Car thieves quickly discovered this technique and began using it to steal cars. Digital thieves have devised a similar attack called a Blind Return-Oriented Programming (Blind ROP, or just BROP) attack. It’s as quiet as a jackhammer on cement, but an attacker can open a remote shell and gain remote code execution on your server if the conditions are right.

Centralized log management: What it is, how centralized logging works, and how to choose the right system

Centralized log management is the practice of collecting logs from across an environment, including applications, servers, containers, networks, and cloud services, and storing them in a single location where they can be searched and analyzed. For operations and security teams, centralized logging is now a core requirement. Without it, logs are scattered across hosts, ephemeral containers, cloud consoles, and disconnected tools. This fragmentation slows troubleshooting, complicates incident response, and limits visibility during security investigations.

Nearly 50% of surveyed cloud-native end-user companies have adopted it, and the project ranks as the second-highest-velocity initiative in the CNCF, behind only Kubernetes. The direction is clear: if your infrastructure doesn’t speak OpenTelemetry, it will increasingly be left out of the observability conversation. But adopting OpenTelemetry across an entire infrastructure is a different problem than adopting it in a greenfield application.

Building a practical OpenTelemetry pipeline with NXLog Platform

Collecting, processing, and forwarding logs and metrics at scale. OpenTelemetry provides a common instrumentation model that makes it easier to collect telemetry data across distributed systems, and many modern applications are adopting it as a standard for generating logs and metrics. However, in practice, you still need to collect, process, and shape the data before it becomes useful. You cannot simply forward raw telemetry data downstream without risking that your observability platform becomes expensive storage instead of a means of maintaining visibility into your environment.

Adopting OpenTelemetry without changing your applications

A practical approach to converting existing logs into modern observability. OpenTelemetry promises a vendor-neutral standard for observability, consistent telemetry, and the flexibility to change backends without rewriting everything. In practice, however, OpenTelemetry adoption often runs into a familiar obstacle: reality. Here’s a common scenario. You’re eager to improve observability, but your environment includes a mix of legacy applications, network devices, and third-party systems. Many of these were never designed for modern instrumentation, and changing them is risky, expensive, or simply not an option.

Current challenges in log and telemetry data management

Today, most enterprises use a security log analytics solution or SIEM (Security Information & Event Management), but analytics are only as good as the data fed into your solution. If you’re missing data sources or are failing to extract full value from the data, you won’t see the big picture. This is an issue new customers commonly mention to NXLog. That’s why one of our key goals is to provide a solid data collection layer that ensures all relevant data is collected and properly fed into the SIEM.

What is a telemetry pipeline? Understanding and building effective telemetry data pipelines

Back in the day, Gordon Moore made relatively accurate observations and projections about the exponential growth of transistors on semiconductors. It still amazes me, yet very few predicted the incredible growth of system interconnectedness and the vast amount of data it generates. It is estimated that 90% of all data was created in the last two years. Given that everything is connected, the need for telemetry is growing at an unprecedented rate, and so is the need to efficiently channel and manage telemetry data.

How to reduce log noise and fight SOC alert fatigue

Do you ever feel like you’re drowning in data? From endpoint logs and firewall events to database auditing and cloud metrics, the sheer amount of data is overwhelming. While telemetry data is crucial for threat detection, incident response, and compliance, it also brings a major challenge: log noise. Log noise obscures meaningful security signals. If left unchecked, you risk increased false positives, overloading security tools, higher SIEM licensing costs, and, most importantly, SOC alert fatigue.

The shadow IT haunting your network: A Halloween horror story

It’s Halloween season, and while everyone else is worried about ghosts and goblins, you—the sysadmin holding the fort—know the real terror: that dusty print server in the corner that’s been running firmware from 2014. Or the Raspberry Pi someone set up to monitor the server room temperature "temporarily" three years ago. Or the CEO’s personal tablet that absolutely must connect to the internal network because "it’s just easier this way.

Watching the watchers: The need for telemetry system observability

Organizations invest heavily in sophisticated monitoring platforms, deploy countless agents across their infrastructure, and build elaborate dashboards to track every metric imaginable. Yet amid this pursuit of comprehensive visibility, a dangerous blind spot often emerges: the observability system itself becomes unobservable. This meta-problem represents one of the most insidious risks in modern infrastructure management. When telemetry collection fails silently—whether due to misconfiguration, infrastructure changes, or system failures—operations teams continue making critical decisions based on incomplete or stale data, unaware that their digital nervous system has developed gaps in coverage.

Detect threats using NXLog and Sigma

The analysis of events produced by various systems and applications can offer insights into the infrastructure health and the operational resilience of an enterprise. From an Infosec perspective, the end-goals are: threat detection, forensics and remediation. However, we can’t query or analyse data that we haven’t collected in the first place! Before threat hunting and incident response are even possible, security events need to be collected from various sources, parsed, transformed, and then forwarded to data sinks such as security information and event managements (SIEM), security analytics platforms, cloud ecosystems and long term storage.

Optimize log management and cut costs

Data logging and event monitoring have become essential to provide security and performance monitoring of business operations. However, the vast volume of logs generated can lead to significant challenges, including high costs and inefficiencies. Many companies collect an excessive number of logs, often missing out on the most critical security-related events. The majority of these logs, known as log noise, offer little to no value to security analysts and can obstruct timely access to high-priority security events.
