AI SIEM: The 6 Components of AI-Based SIEM

AI is fundamentally transforming SIEM (Security Information and Event Management) systems, marking a significant shift in cybersecurity. By integrating AI, SIEM solutions are evolving beyond traditional, rule-based frameworks, offering enhanced threat detection, predictive analytics, and automated response mechanisms. This integration addresses the increasing complexity and volume of cyber threats, making cybersecurity more proactive and intelligence-driven. This article will explore how AI-driven SIEM is reshaping cybersecurity, focusing on the challenges of legacy SIEM systems and the opportunities presented by AI and machine learning. You’re welcome to learn more about AI/ML in cybersecurity here.

What Is AI-Based SIEM?

SIEM systems transformed the cybersecurity landscape at their inception – offering a new way to consolidate piecemeal security information into a cohesive whole. Now, by integrating Artificial Intelligence (AI) and Machine Learning (ML), these solutions can not only ingest and normalize vast swathes of data – but they can also analyze patterns and anomalies that might indicate a security incident.

One of the fundamental processes in AI-based SIEM is data aggregation. This refers to the collection of security data from a multitude of sources, including network devices, servers, databases, applications, and more. The range of data collected is extensive and includes logs, event data, threat intelligence, and other types of security-related information. In a diverse digital environment, this data aggregation is crucial, as it provides a comprehensive view of the security posture of an organization. However, the challenge lies in the diversity of the data formats and structures. This is where normalization comes into play. Normalization is the process of converting raw security data from various sources into a consistent, standardized format. This step is critical for ensuring that the AI SIEM system can accurately analyze and correlate the data, irrespective of its origin. It involves aligning disparate data types and formats into a unified model, making it easier for AI algorithms to process and analyze the data effectively.

The standout feature of AI SIEM systems is their ability to automate these crucial processes of data aggregation and normalization. Leveraging AI and ML, these systems can sift through data much faster, intelligently sorting, aggregating, and normalizing security data. This automation significantly reduces the time and effort traditionally required for these tasks, allowing security teams to focus on more strategic aspects of cybersecurity.

Once the data is aggregated and normalized, AI-based SIEM utilizes AI algorithms to enhance threat detection. These algorithms are trained to recognize the signatures of known threats and detect new, evolving threats through the analysis of behavior patterns. This capability is vital in an ever-changing threat landscape. By leveraging the power of AI and ML, these systems can foresee potential security breaches before they occur. This predictive analysis is grounded in the examination of trends and patterns within the data, allowing organizations to proactively reinforce their defenses against anticipated threats.

Before delving into the unique components of AI-driven SIEM, learn more about what SIEM is here.

6 Components of AI-Driven SIEM

The increased capacity of AI-driven SIEM can make it seem intimidating – or overhyped. A deep dive into the new and improved components can shed some light on the true capabilities of the next stage in SIEM evolution.

#1. Data Handling

AI SIEM systems start by aggregating data from various sources like network devices, servers, databases, and applications. This event data spans the breadth of your network infrastructure, but the events generated by servers, cloud devices, and Wi-Fi access points are almost always in different forms – while applications create constant streams of logs, Firewalls might have their own event data and security-related information to handle. The sheer diversity of this data has massively slowed down manual analysis efforts in the past, creating severe downstream delays. SIEM tackles this through normalization – after ingestion, the raw data is converted into a standardized format, ensuring consistency and accuracy in data analysis irrespective of the source. AI and ML significantly automate these processes, enhancing the speed and intelligence with which security data is aggregated and normalized, once again reducing the manual effort and time involved.
This is thanks to the following components:

#2. Big Data Sources

Traditional SIEM lies in close proximity to AI’s Big Data approach – the first just handles data ingestion on a far smaller scale. The new architecture surrounding AI’s data-hungry approach has seen incredible improvements in how we handle large volumes of information. One example is Big Data ETL – which streamlines the process of loading data to centralized data lakes into a well-defined, consistent, and real-time process. This massive upgrade allows your SIEM to access the enormous amounts of information swirling around your tech stack – and extract the important features. This approach unlocks vastly more scope for the sheer quantity of data being ingested by your SIEM tooling.
However, it’s not just more of the same data points being included: AI unlocks whole new avenues of analysis. For instance, NLP can be used to analyze text-based data like system logs, network traffic, and user communications for potential threats. This way, instead of relying solely on log analysis, AI now grants identification of social engineering attacks within internal and public-facing communications to be a part of your AI-driven SIEM capabilities. While NLP focuses solely on language analytics, AI SIEM features User and Entity Behavior Analytics (UEBA), which uses ML algorithms to understand the normal behavior of users and entities and detect deviations that may indicate a threat.

#3. Data Enrichment

Every individual piece of data acts as a brick in your organization’s defensive walls – however, it’s vital to ensure that these data points are as high-quality as possible. This is where data enrichment comes into a league of its own. Relevant extra info can be as simple as geolocation data: by identifying the IP address, analysts are granted a snapshot into location-based behavior. Identity context can further play an important role in automated data enrichment. Given that IAM systems help dictate and define an end-user’s behavior, cross-referencing their logs with this in real-time can help illuminate any causes of concern.

#4. Pattern Recognition

While user behavior, log normalization, and enrichment all help give you the most inclusive picture of your tech stack possible, SIEM thrives in its ability to analyze the entirety of your tech stack in real-time. In this way, it’s possible to cut out the noise and focus on the subtle anomalies that might indicate a security breach.

These algorithms can further process unstructured data like documents, binary files, and images, enabling the analysis of a wide range of data sources for potential threats. The enriched data is correlated to specific entities such as users, hosts, or IP addresses, facilitating event aggregation and enabling the search of enriched events across various data sources. This correlation aids in aggregating risk scores and attributing them to entities – when cross-referenced against a baseline of ‘normal’ behavior, AI SIEM’s pattern recognition can identify correlations that humans may not connect up.

#5. Automated Incident Response

In the event of a detected threat, AI grants SIEM systems the ability to automate parts of the incident response process. This includes automatically triggering alerts, implementing predefined response actions, or orchestrating complex response workflows. One such example is that of the automated dynamic workflow – where the workflow put in place following a potential threat is tailored to the threat in question.

#6. Predictive Analytics

AI SIEM systems utilize predictive analytics to forecast potential future threats by analyzing historical security data and identifying patterns. This capability allows organizations to proactively secure their systems, rather than reacting to threats as they occur. This knowledge base allows for the AI models at the core of the solution to build increasingly accurate security responses and incident prevention approaches as time goes on and more data is accumulated.

The continuous learning from issues in the past enhances the accuracy and robustness of AI-based SIEM systems against increasingly vicious cyber threats. Ultimately, AI-driven SIEM integrates various components like AI, ML, deep learning, NLP, and UEBA, all of which enhance traditional SIEM capabilities. This integration leads to more intelligent, efficient, and proactive cybersecurity measures – crucial in the ever-evolving landscape of cyber threats.

How AI-Driven SIEM Can Improve Your SOC

Legacy SIEM approaches have left teams open to both attacks and overwhelming quantities of false alarms. This is because traditional SIEM relies heavily on predefined threat signatures and policies for handling threats. This approach struggles with zero-day attacks and sophisticated techniques that are not yet profiled in cybersecurity frameworks. AI SIEM streamlines the processes of collecting security data from diverse sources and converting this raw data into a consistent, standardized format. It also enhances data with additional information like threat intelligence, drastically reducing your team’s reliance on manual rule implementation.

While conventional SIEM systems offer scalability, they often fall short in handling the immense data volume and complexity associated with modern networks influenced by AI. The sheer volume of logs and event information can be overwhelming, making it challenging to effectively monitor and respond. This limitation can be exploited by bad actors to execute distributed attacks that surpass the capabilities of traditional SIEM systems. AI-based SIEM is able to analyze vast quantities of data on a scale otherwise unreachable.

Finally, traditional SIEM systems have come across several stumbling blocks within their implementation. Rule-based SIEM requires a large number of trained employees to verify alerts and remediate issues. However, the cybersecurity field is stretched perilously thin, with a drought of highly-trained personnel. For those already trained and in the field, constant alerts can keep them perilously close to burnout. As revolutionary as AI-driven SIEM is on data collection and analysis, the human impact is just as vital. For instance, team members are saved from the time-consuming tasks of manual agent implementation and data analysis. Automated
incident response mechanisms streamline the process of addressing threats, reducing the time and manpower needed for each incident. Finally – and arguably most important – AI’s ability to learn and tell the difference between normal and suspicious activities, which reduces the number of false positives and allows teams to concentrate on the real threats.

The rate of advancement that AI is currently undergoing is cause for even more optimism: the ability for complex rulesets and threat management to be translated into plain English is an arm of AI-driven SIEM that could help bridge the knowledge gap currently threatening entire industries.
