What is Splunk? Important Things You Need to Know?

As the world is becoming largely dependent on digital tech to enjoy the ease of access, the need for protecting data has assumed unprecedented significance. A large number of businesses and other organizations now store data on the cloud and leverage them to improve their services. While they cannot afford to compromise with either the data security or accuracy. Splunk delivers precisely this.

Overview

Splunk is a Security Information and Event Management (SIEM) platform dedicated to collecting, analyzing, and correlating data in real-time. The tool facilitates monitoring and troubleshooting across all environments, offers security for the cloud journey, gives predictive service intelligence as well as observability for rapid innovation. Join Splunk Course online to learn more about this platform.

Acknowledging the importance of cloud storage in modernization, the platform also helps organizations handle related complexity and accelerate their multi-cloud and hybrid strategies.

Why Splunk?

Get desired speed and accuracy

It feeds organizations with all the intelligence required to fend off any threat to data privacy be it access to controls, monitoring or encryption.

According to the company, the platform does away with the barriers between data and action to facilitate “observability, IT and security teams to ensure their organizations are secure, resilient, and innovative”.

Speed with accuracy is what makes Splunk stand out from other SIEM systems. It provides security teams with the perfect platform to scrutinize a vast pool of data, identify malicious network activity, and take actions to thwart threats much more efficiently and in significantly less time.

How the tool works

The tool remains active round the clock to keep track of every minute network and user activity in order to arm the relevant security teams with a thorough report on the threat that they can refer to for strengthening their cybersecurity.

It functions on an advanced automatic system to delegate tasks and monitor workflows to expedite the entire service and security process, which if done manually would not only consume a lot of precious time but will also be prone to errors and oversights.

Apart from creating a huge database to maintain audit preparedness, the tool’s other key security monitoring features include automated event alerts and event log collection across devices, applications, and user activity; graphical user dashboards; and pre-defined and customizable correlation parameters.

The platform believes in the prevention-is-better-than-cure principle as advanced threat detection is its forte. Splunk can detect and contextualize threats or high-risk activity in real-time owing to its non-stop monitoring of user behavior, applications, and other network resources across environments.

Any suspected activity prompts the tool to launch cross-correlation of event logs to confirm the threat. As soon as a threat is confirmed, Splunk’s Adaptive Response Framework sends out event alerts with threat prioritization, automates response workflow, and pulls the relevant threat information across devices and environments.

The real-time intervention helps the security team concerned to neutralise the threat before the network or data privacy is compromised.

Some of the steps taken by the platform to nip the threat in the bud include end-to-end network visibility and analytics, intelligent threat classification, event log correlation, detecting advanced threats with kill chain methodology, and user behavior analytics.

Key benefits of Splunk

Multiple sources

Splunk has access to data from multiple sources, including log files, event logs, Syslog, and SNMP, that users can leverage to enhance their services and cybersecurity.

Indexing

As soon as Splunk is installed, it absorbs all the available data with any changes. It resorts to field extraction later. The tool then allows users to gather and index the available data as per their requirements. It then processes the incoming data before allowing its storage.

Compatibility

The tool is not just available on multiple platforms, but also quickly and easily compatible with any software. This is majorly due to there is no backend to manage nor any database is required for Splunk. Further, if installed on multiple servers, data is distributed across the servers evenly.
