They are vital for any computing system as they throw light on all the changes that have occured in a system or an environment. This helps the users to analyse and understand the situation, and if there is a problem, it can be used to backtrace to the root cause. When dealing with scalable systems, it is always required to have a protocol for log management.
One such approach is centralized Log management where the logs generated by various subsystems are sorted, parsed and stored in a central repository at the system level. This will essentially reduce the effort in identifying issues. ELK is a collection of Elasticsearch — a highly scalable analytics search engine, logstash — a tool for parsing, analyzing data and kibana — an interactive GUI tool for visualization. It is an open source software.
It is developed in Java and is basically a wrapper on Apache Lucene Library. It has no schema with JSON documents where all the data is stored. Similar to MongoDB, it is very easy to set it as it has no schema.
Graylog is a powerful log management software developed to cater to the need of processing, analyzing and understanding terabytes of log data. It also offers an open source package for users to get hands on experience.
Overall, both the tools have their own pros and cons as we have seen earlier. Selecting a tool is completely based on the system and its requirements. It is up to the users to decide which suits them better. There are hybrid applications in which both can be used. This is a guide to Graylog vs ELK.
Free Software Development Course. ELK supports all the majority of data types like json etc. Third party plugins can be used for data conversion. ELK stack supports log management and log analysis along with its other functionalities. It is a multipurpose stack. And the alerts are based on stream data. Builtin alerting is not available but third party plugins like X-pack could be used to send alerts to the users.Blue Tech is proud to offer Grayloga leading centralized log management solution built to open standards for capturing, storing, and enabling real-time analysis of terabytes of machine data.

All Rights Reserved.When working in a classic IT infrastructure you often face the problem that developers only have access to test or development environments, but not to production.
In order to fix bugs or to have a glance at the system running in production, log file access is needed. This is often not possible due to security requirements. The result of this situation is that the operation guys need to provide these files to the developers, which can take a certain amount of time. A solution to these problems is to provide a Log Management Server and grant access to the developers via a UI.
The advantage of using open source technology is that you can — but do not have to — buy subscriptions. The problem is that you have to pay more if the volume of logs increases either due to a raised log level to help analyze some bugs in production or simply as more services are deployed. You can basically ship your log events to a cloud service, which then takes care of the rest. You do not have to provide any infrastructure yourself.
This is a very good solution unless the security policy of your organization prohibits shipping data to the cloud. Of course this overview is incomplete. I just picked some tools for a brief introduction.
If you think something is missing, feel free to blog or comment about it. At the moment, the probably most famous open source log management solution is the ELK-Stack. It is called a stack because it is not one software package but a combination of well-known open source tools.
The components are:. Despite all the good things about the ELK-Stack there are some drawbacks, which would make it not the optimal choice under some circumstances. Kibana has no user management.
How to Use Graylog for Software Monitoring
Next, there is no housekeeping for the Elasticsearch database. Logstash creates an index for each day. You have to remove it manually if you do not need it anymore. Graylog is an alternative log management platform that addresses the drawbacks of the ELK stack and is quite mature. It provides an UI and a server part. Moreover, Graylog uses Elasticsearch as database for the log messages as well as MongoDB for application data.
The server part provides a consistent management of the log files. The Graylog server has the following features:.An intrusion detection system IDS is a well-established network security technology that has different classifications, but all follow a similar pattern outlined below:.
In this post, we will be using one of the most popular IDS tools: Snort. We will be excluding host based IDS HIDS - analyzing activity that happens within an operating system but some of the ideas can be applied to these set of tools as well. Once you have Snort installed and configuredwe will be sending the triggered alerts into Graylog.
Next, configure the local syslog daemon to forward logs to Graylog. If you are using rsyslog, it would look like the following:. You can find instructions for sending other syslog daemons into Graylog here. Note that in the above example, we are forwarding only the Snort alerts which we are writing to the local5 facility. Alternatively, you could also configure it to forward all syslog messages.
In Graylog, set up a UDP syslog input at the port and network interface you configured in rsyslog earlier and confirm that messages are arriving. We will set up a Graylog Processing Pipeline to identify snort logs and parse the alert into a message with extracted fields. It is important that all your sensors and sources send in source addresses in the field with the same name. If source addresses are being sent with differing names, analysis will become quite painful.
A very useful source of log messages to correlate IDS logs with is network connection logs. They provide a high level overview on the IP address, time communicated, and port and protocol used. The most popular way to collect network layer logs is forwarding them directly from your routers, firewalls and switches using a protocol like Netflow, and into Graylog.
Graylog Netflow Input. You can read more about this topic in our previous blog post. By searching for all connections and alerts that came from the same IP address that triggered an IDS alert, you can get the following information:.
This explains that the IP address If we are also sending all operating system logs into Graylog, we will be able to see a list of denied login attempts. We could either execute a full text search, or, if we have a processing pipeline rule in place that extracts SSH login attempt IP addresses into fields, we could run a more specific search like this:.
Thanks to the IDS alert, we were able to dig deeper into the issue and detected a successful infiltration of our systems. In order for easier visibility of information, a dashboard, like the one below, will provide an excellent overview.
This will allow for you to take immediate action and protect your network and system. Our final post in our three part series on security focuses on configuring IDS alerts in an open source environment. We will walk through integrating the IDS tool, Snortwith Graylog in order to detect and analyze suspicious activity.
We will then provide examples of correlating IDS alerts with both network connection and operating system logs using Graylog.Graylog 3. In case you need to configure legacy Collector Sidecar please refer to the Graylog Collector Sidecar documentation.
We encourage users to migrate to the new Sidecarwhich is covered by this document. Graylog Sidecar is a lightweight configuration management system for different log collectors, also called Backends.
The Graylog node s act as a centralized hub containing the configurations of log collectors. The log collector configurations are centrally managed through the Graylog web interface. On its first run, or when a configuration change has been detected, Sidecar will generate render relevant backend configuration files. Then it will start, or restart, those reconfigured log collectors. You can get. For Windows, you can download the installer from here.
All following commands should be executed on the remote machine where you want to collect log data from. Install the Graylog Sidecar repository configuration and Graylog Sidecar itself with the following commands:. Edit the configuration see Configuration and activate the Sidecar as a system service:.
Optionally edit the configuration see Configuration and register the system service:. Next up, you can decide which collectors you want to use with your Sidecar and install them as well. We only cover the installation of the most common ones here, but you are free to use other collectors as well. Install Filebeat or another Beats package by following the instructions on the official Filebeat download page.
The Windows Sidecar package already includes Filebeat and Winlogbeat. For other Beats packages follow the instructions on the official Beats download page. Because the Sidecar takes control of stopping and starting NXlog it is necessary to stop all running instances of NXlog and unconfigure the default system service:.
Install the NXLog package from the official download page and deactivate the system service.
We just need the binaries installed on the system:.Gather and aggregate incident data to proactively go looking for malware, hacks, phishing, and endpoint attacks.
