Will threat intelligence add strength to SIEM?

The hyper-efficient combo of both SIEM and Threat Intelligence adds more strength when carefully planned and configured. Integrating threat intelligence intoSIEM with a blind trust can become complicated or problematic.

Myth: The bigger the threat intelligence, the better the detection.

Truth: Optimizing the data to threat intelligence must be legit for the SIEM to detect efficiently.

Carefully interconnecting the workflow processes, automation, and analyst interaction will make sure you feed considerable value of data with the threat intelligence. Integrating without proper planning will make the situation worse. The proper way is to plan, consider, and integrate under expert guidance for any organization.

In this blog, you will learn What SIEM ss and Why Threat Intelligence and Security information and event management (SIEM) systems are key components for security operations. 

Also, learn to incorporate cyber threat intelligence (CTI) to get more value from your SIEM.

SIEM Overview

The term SIEM was invented in 2005 by two security analysts Mark Nicolett and Amrit Williams in a report on how to improve IT security with the help of vulnerability management. They suggested an advanced security information management system based on two previous generations (SIM and SEM).

Security Information Management (SIM) – The first generation security system that collects logs and manages. These log data are stored and used for analysis and reporting with threat intelligence.

Security Event Management (SEM) – The second-generation security system that aggregates, correlates, and notifies all the events from security systems such as antivirus, firewalls, and Intrusion Detection Systems (IDS), authentication reports, SNMP traps, servers, databases, etc.

Security Information and Event Management (SIEM) – The system invented by Mark Nicolett and Amrit Williams works on the concept of providing actionable information from log entries and events acquired from both SIM and SEM.

The actionable information provided from SIEM helps the cyber security team to detect and respond to threats in real-time. The security team can also investigate past threat incidents and prepare audit reports.

The SIEM team collects historical log data and real-time events from SIM and SEM respectively and shares them with the security team to help them sort out the unusual happenings and vulnerabilities in the organization’s network.

SIEM focuses on threat-based incidents and events namely successful or failed logins, malware activities, changes in privilege accesses. These changes are sent as alert notifications on SIEM’s dashboard notifying the security analysts who maintain the SIEM platform in the respective organization.

Capabilities of SIEM:

(Capabilities SIEM: – Create Infographics)

Threat Identification: SIEMs detect complex threats with automatic behavioral profiling that the correlation rules can’t detect or respond to.

Detection of Unknown attacks: SIEM uses machine learning to detect unknown attacks that come with pre-existing definitions or manually defined rules or signatures.

Ingenious Movements: SIEMs analyses and detect any ingenious movements that hackers use to move through a network using IP addresses, credentials, or individual machines, search for important assets stored on the network.

Behavior Analyses:  SIEMs learn the behavioral patterns automatically and detect any suspicious behavior occurring in the network.

Automated Threat Response: SIEM executes pre-planned sequential actions to hold and lessen the impact of the attack automatically. SIEM is becoming a full security Security Orchestration, Automation, and Response(SOAR) tool.

SIEM Enhancing Security Operations Center

Security Operations Center(SOC) stations the information security team making it responsible for monitoring and analyzing the organization’s cyber security defense lines on a daily basis. This scheduled team detects and responds to cyber threats/attacks or any unusual behavior happening in the network using their technology and framed strategies.

For bigger enterprises and corporations, SIEM acts as the foremost piece for Security Operation Center. The SIEM software helps the SOC team to collect all the log data from multiple resources inside their organizational network and to analyze, evaluate and correlate the security events. The correlated events are then analyzed by SIEM to detect known threats.

SIEM platforms are extremely helpful to organizations that consist SOC team since they are challenged to continuously learn and understand the ever-evolving new threats in their cyber environment.

Threat intelligence integrated with a modern SIEM

SIEM contributes a wider part to an organization’s security with its mixture of logs and events from its various sets of sources. SIEM puts together the informations collected in order to identify threats and to respond to the situation.

However, with the overwhelming informations received into the SIEM platform causes tightness to the SIEM analyst in learning and understanding of threats, security planning, and results in lack of cybersecurity maintenance in the organization. 

To reduce this tightness, an SIEM analyst has two choices: Re-engineer everything or Integrate threat intelligence with SIEM that can improve threat detection better. Integrating threat intelligence will help the SIEM analyst or the security team to prioritize with most important threats that are to be dealt immediately. The threat intelligence provides alerts to the analyst according to the severity of the threat entering the organization’s network.

This way, the analyst can learn and understand the most damage causing threats, can strategise and plan the threat response system, and can maintain the defense line more efficiently.

Implementing and working of SIEM in global corporations can be hectic as they provide overwhelming amounts of information and more false positives. This weakens their internal/external network, endpoints, and their cybersecurity system followed by the organization.

Engineering the SIEM to large corporations is really challenging and hard to maintain. The SIEM analysts will lose control over the security system with overwhelming information provided  by SIEM.

Threat intelligence feeds are one solution to this challenge. 

Threat intelligence feeds are sources of information gathered from security researchers and threat analysts to provide the information to security organizations to better their cybersecurity defense mechanism. 

These gathered data and information from third party allows the security analysts to be awake of the threats experienced by other enterprises in the cyber industry.

The threat-intelligence feeds are available as both free(Open Source) and also paid(Subscription based). The security team can access to both in order to frame their security strategies for their organization. These threat intelligence fees are mostly in a standard format and are allowed to be shared with other organizations.

Open source intelligence feeds that are offered free contain large data from various participants. But, not all the data provided are true. Open source feeds are high in volume but not everything is legit. The untrue data present in the open source intelligence feeds can be a waste of time since the security analyst has to respond to more false positive data.

The organization that offers threat intelligence feeds on subscription basis focuses on collection data, reviewing the collected data and information, reverse engineering the threats, and providing insights to the nature of the threats found.

The subscription based intelligence feeds also focuses on providing very lesser false positives compared to open source intelligence feeds. This is because there are security teams of researchers and analysts that validate and review these intelligence feeds before they let others consume these feeds.

These feeds are used to provide alerts and warnings to the organization that uses the threat intelligence. The alerts and warnings from these feeds provide the most immediate value to SOCs. 

This information is valuable for SOCs with limited resources and also for SOCs with unlimited budgets. The shared information within the security community from verified and knowledgeable security engineers is useful to all.

Threat Intelligence Is Useful for All Security Organizations

Every industry that is into the cyberworld is increasingly facing cyberthreats in this era. It is no longer a matter of if an attack will happen, it is a matter of when. The companies that are suffering and are yet to suffer from cyberattacks require enough information that gives them more awareness about the threats floating around the internet network. With this information, they’ll be able to decide on how to respond to these threats.

Implementing the threat intelligence system with SIEM can give valuable insights from the global threat intelligence feed providers. These feeds will provide warnings and alerts about new threats to the SOC team in respective organizations.

This improves the cybersecurity defense line of any organization.

Threat Intelligence powering the SIEM is a mandatory move that every company should make.

Best Practices for Your SIEM Integration with Threat Intelligence

Here are the best practices that you can follow while integrating Threat Intelligence into your SIEM:

Get a threat intelligence that is efficient enough to provide more accurate threat feeds. For example, the threat intelligence must be able to give data feeds that are more relevant and lesser false positives. Such intelligence feeds are said to be actionable feeds that are very much useful to SOCs.

For a threat intelligence to efficient and actionable, it must have the following qualities:

Higher Relevancy: Receiving threat intelligence feeds that are not relevant and that are with more false positives is completely a waste of time. They expose more vulnerabilities of the organization.

Well-Timed: The threat intelligence must arrive swiftly at the right time so that it can be useful to the SOC team present in the organization.

Complete information: The threat intelligence needs to provide complete information about the new threats so that it can ease the decision making process rather than complicating it by providing incomplete information.

Precision: The feeds generated and shared with the threat intelligence community must be of high accuracy and precise feeds containing lesser false positives.


Organizations now are quickly adapting to threat intelligence integrations with their SIEM systems. Since threat intelligence adds more value and strength to the cybersecurity of an organization, every organization that contains potential data online and wants to secure them tight must adapt to threat intelligence.
