Best SIEM Tools

Security information and event management (SIEM), which combines security information management (SIM) and security event management (SEM), provides real-time event monitoring and analysis as well as tracking and logging of security data for compliance or auditing needs.

Simply said, SIEM is a security tool that aids companies in identifying possible security flaws and threats before they have a chance to interfere with daily operations. For security and compliance management use cases, it surfaces user behavior abnormalities and employs artificial intelligence to automate many of the manual operations related to threat identification and incident response. It has become a mainstay in contemporary security operation centers (SOCs).

Throughout time, SIEM has developed into something more than the log management technologies that came before it. Thanks to the power of AI and machine learning, SIEM now provides powerful user and entity behavior analytics (UEBA). It is a very effective data orchestration solution for handling constantly changing risks as well as reporting and regulatory compliance.

This article is basically about SIEM tools. You will find information on the following topics related to SIEM tools:

• Who uses SIEM software?

• Which are the Top Open-Source SIEM Tools?

• Which are the Top Commercial SIEM Tools?

• What is the Difference Between SIEM Tools?

• What are SIEM alternatives?

Who uses SIEM software?

With a high number of devices connected to their networks, enterprise organizations invest in SIEM technologies, which enable them to gather log data from hardware, operating systems, apps, and security tools to continuously monitor their networks. Moreover, these businesses assign IT workers to system upkeep, security monitoring, and attack response. ArcSight ESM (Enterprise Security Management), AT&T Cybersecurity (formerly known as AlienVault), Fortinet, IBM QRadar, McAfee SIEM, and Splunk are a few popular SIEM examples you may be familiar with.

The SIEM software is not a viable alternative for the majority of small enterprises due to its breadth and resource needs. However, the software can be too expensive for many small enterprises, costing tens of thousands of dollars annually. Thus, SIEM is typically a superior option for business security.

Which are the Top Open-Source SIEM Tools?

There is no open-source SIEM solution that is entirely flawless. As there isn't a single fully functional open-source SIEM, this is also not a list of them. Current solutions either require merging with other tools or lack fundamental SIEM features like event correlation and reporting. But if you decide to undertake the challenging task of creating your own SIEM from scratch using open-source software, these are the parts we believe you ought to employ. Best open-source SIEM solutions are explained below:

1. OSSEC

2. OSSIM

3. ELK Stack

4. OpenSearch

5. Prelude

6. Suricata

7. Snort

8. SecurityOnion

9. MozDef

OSSEC

OSSEC is a well-liked host intrusion detection system (HIDS) that is open-source and compatible with a number of different operating systems, including Linux, Windows, Macintosh, Solaris, OpenBSD, and FreeBSD.

The manager (or server), which is in charge of gathering log data from various data sources, and the agents, which are software programs in charge of gathering, processing, and making the logs simpler to examine, are the two primary parts of OSSEC.

There is no visualization layer included in the OSSEC project itself. The advice is to utilize external visualization tools like Kibana and Grafana instead of the UI that was deprecated.

OSSEC keeps an eye on a variety of host-specific factors directly. Log files, file integrity, rootkit detection, and Windows registry monitoring are all included in this. Other network services, such as the majority of well-known open-source FTP, mail, DNS, database, web, firewall, and network-based IDS solutions, may be analyzed using OSSEC. OSSEC may also examine the logs produced by a variety of paid network services and security programs.

As part of automated intrusion detection or active response systems, OSSEC offers a variety of alerting alternatives. A simple log storage engine is used by OSSEC. Host agent log messages are not kept around by default. OSSEC deletes these logs after analysis unless the logall> option is present in the ossec.conf file for the OSSEC management. OSSEC keeps the receiving logs from agents in a text file that is rotated daily if this option is enabled.

It is debated whether OSSEC qualifies as an "all in one" SIEM system. OSSEC undoubtedly puts in the effort necessary to set up a SIEM system by gathering and analyzing data, but it is missing some of the essential elements for log management and analysis. It's important to note that other HIDS solutions (such as Wazuh) have cloned the OSSEC project, extending its features and transforming it into a more comprehensive SIEM alternative.

OSSIM

Unified Security Management (USM) by AlienVault's open-source product, OSSIM, is perhaps one of the most well-known open-source SIEM solutions. Important SIEM elements, including event gathering, processing, and normalization, are included in OSSIM.

To create a comprehensive SIEM, OSSIM integrates native log storage and correlation features with a number of open-source projects. OSSIM contains FProbe, Munin, Nagios, NFSen/NFDump, OpenVAS, OSSEC, PRADS, Snort, Suricata, and TCPTrack among its list of open-source projects. The SIEM will undoubtedly demand more management time to maintain as a result of the additional open-source projects you add to the mix.

The addition of OpenVAS is particularly noteworthy because OpenVAS uses IDS logs and vulnerability scanner data to identify vulnerabilities.

As might be expected, the open-source OSSIM has fewer features than its for-profit counterpart, and both have serious scaling issues, even in small situations. The open-source version of OSSIM has almost no log management functionality.

ELK Stack

When it ceased to be really open source, the ELK stack was likely the most well-liked open-source product used as a foundation in a SIEM system. Indeed, a construction block. A comprehensive SIEM system is not necessary since there is much area for disagreement on whether the ELK Stack counts as an "all in one" SIEM system.

Elasticsearch, Logstash, Kibana, and the Beats family of log shippers make up the ELK stack. As of January 14, 2021, Elasticsearch and Kibana are covered under SSPL licensing.

A log aggregator called Logstash can gather and analyze information from virtually any data source. Any log data that it gathers can be enhanced by filtering, processing, correlating, and other means. The storage engine and one of the top options for indexing and storing time-series data is elasticsearch. The visualization layer in the stack is Kibana, and it's a very potent one at that. The data collection and Logstash shipping into the stack are the responsibilities of Beats, which consists of a number of lightweight log shippers.

To gather logs, Logstash makes use of a variety of input plugins. However, it incorporates data from more specialized programs like OSSEC or Snort. The log processing, storage, and visualization powers of the ELK Stack are functionally unrivaled. Yet the ELK Stack, at least in the free version provided by Elastic, is lacking several essential elements for SIEM.

There isn't any built-in reporting or alerting feature, first and foremost. This is a well-known sore issue for customers attempting to utilize the stack for security as well as for more typical use cases, including IT operations. The Elastic X-Pack, a for-profit solution, or open-source security add-ons may both be used to provide alerting.

Moreover, there are no applicable built-in security restrictions. The stack becomes somewhat more expensive to manage as a result, both in terms of resources and operating expenses.

OpenSearch

As a derivative of the Elasticsearch and Kibana projects, OpenSearch is an open-source software project that was started in 2021 with development overseen by Amazon Web Services. The project consists of an OpenSearch-branded database and OpenSearch Dashboards, which are front-end visualization and analytics tools.

Elastic, the company that created the Elastic Stack, also known as the ELK Stack or Elastic Stack and made up of the Elasticsearch, Kibana, Beats, and Logstash projects, announced in January 2021 that it would switch to a dual licensing model based on the Server Side Public License (SSPL) and the Elastic License, neither of which have been acknowledged as open source licenses by the Open Source Initiative (OSI). As a result, Logz.io collaborated with Amazon and other top business players to develop OpenSearch, an open-source alternative to the recently closed-source ELK stack.

Several businesses utilize OpenSearch as a custom logging repository for security data. Due to the fact that any basic SIEM functionality, such as security detections, content, analytics, and threat enrichment, must be manually implemented, it cannot be considered a SIEM per se. Yet it is a cost-effective and future-proof strategy for firms with a lot of technical skill but little funding.

Prelude

Prelude is a SIEM framework that integrates several other open-source tools, much like OSSIM does. Moreover, it is an open-source variation of the identical commercial program, much like OSSIM. Prelude tries to perform the functions left unfilled by programs like OSSEC and Snort.

Prelude uses the Intrusion Detection Message Exchange Format to store all of the logs and events it receives from various sources in a single area (IDMEF). It offers tools for filtering, correlating, alerting, analyzing, and visualizing.

Prelude's open-source version is severely constrained to OSSIM in comparison to the commercial product in terms of all of these features, which is possibly why it is not especially well-liked. Prelude OSS is intended for evaluation, research, and test purposes on extremely tiny settings, according to the official documentation. Please be aware that Prelude OSS performances are significantly worse than Prelude SIEM.

Suricata

By serving as a common intrusion detection system (IDS), PCAP processing, intrusion prevention, and network monitoring tool, it has eroded Snort's user base. The Open Information Security Foundation (OISF) is its owner. It is uniquely constructed using the Lua programming language, which is a compact, quick, and embeddable language.

For other databases like Elasticsearch and Splunk, it maintains integrations in YAML and JSON. While there are minor variations, it employs many of the same principles as Snort. It can identify HTTP and SSH traffic using application-layer detection rather than OpenAppID.

It is better at handling problems with contemporary computers because it is a newer tool. Instead of Snort executing several instances on a single thread, it supports multithreading natively.

Snort

Network intrusion detection system (NIDS) for Windows and Linux called Snort. It differs from other host-based solutions like OSSEC because of this. In light of this, Snort is not necessarily a replacement for OSSEC or other SIEMs but rather a potential addition.

Being a packet sniffer that can "sniff" out security dangers to networks, Snort derives its name. It recognizes and reports attack vectors, alerting syslog or another channel as a result. Together with logs, it does real-time traffic analysis. A broad variety of diverse attack vectors, such as OS fingerprinting, DDOS, CGI, SMB probes, buffer overflows, and stealth port scans, are among the many things it is made to identify. It recognizes apps using OpenAppID.

Martin Roesch, the Snort program's founder, put together Sourcefire to oversee the software for its hundreds of thousands of users. Cisco purchased Sourcefire in 2013, but Snort's open-source roots remain (while Cisco has gone on to develop commercial alternatives based on the original software).

Snort 3.0, the most recent major version, was released in January 2021 and solved numerous issues with Snort 2.x, notably the absence of multithreading. Suricata and Snort are frequently contrasted, and Snort may be used in place of Suricata.

SecurityOnion

A free Linux distribution (distro) for intrusion detection and business security monitoring is SecurityOnion (ESM). Several open-source initiatives including the ELK Stack, OpenSearch, OSSEC, Snort, Suricata, and others are leveraged by this project. Doug Burks created it and released it in 2008; he then introduced Security Onion Solutions in 2014.

It offers full packet capture (FPC) through netsniff-ng and host-based and network-based intrusion detection systems (IDS) for detecting network-based vulnerabilities including data exfiltration and malware (other open-source options for FPC include GUI-based TCPDUMP and command-line interface Wireshark).

Users have the option of Snort or Suricata for network-based IDS, and Wazuh for host-based IDS (also known as HIDS).

MozDef

MozDef security incident and response automation tool was created by the Firefox-famous firm using other open-source technologies as a portmanteau for Mozilla Defense (and possibly more significantly, as a nod to rapper-activist Mos Def). 2014 saw its initial release.

A Docker container is used to operate each service in its architecture. According to Mozilla, it is a SIEM add-on that uses Python to create new rules and Elasticsearch as a logging engine.

According to the MozDef documentation, they can output JSON to HTTP(S) or rabbit-mq and interface with a variety of log shippers. Also, it is compatible with Amazon CloudTrail and GuardDuty. They cite the subsequent open-source tools as their foundation in addition to those already mentioned: Nginx, Meteor, MongoDB, VERIS (from Verizon), and several JavaScript or Python-related technologies.

Table 1. Differences Between SIEM solutions

What are SIEM alternatives?

Due to the high expense of acquiring and installing SIEM systems, businesses are now looking at alternative security analytics technologies and attack detection and response strategies. SIEM alternatives are as follows:

• Platforms for event collection and analytics: Products for event collection and analytics offer both SIEM and nonsecurity use cases, as well as more straightforward cost allocation techniques. Yet, a SIEM product could not have all of its potentials.

• Products for extended detection and response: For companies ready to commit to vendor-defined and vendor-managed threat detection and response solutions, extended detection and response(XDR) platforms provide automated hands-off capabilities inside the products.

• Managed detection and response services: Instead of escalating security events to the clients, managed detection and response (MDR) service providers look into, validate, and react to them.
