SIEM Architecture and Best Operational Practices for Modern Security Operations

Security information and event management (SIEM) is a security management approach that combines security information management (SIM) and security event management (SEM) functions into a single system. SIEM platforms collect log and event data from security systems, networks, and computers, and convert it into actionable security insights.


A security management system that can help organizations improve their security posture in a number of ways, SIEM can spot threats that individual security systems cannot see, examine past security incidents, perform incident response, and prepare reports for regulation and compliance purposes. Also, security information and event management (SIEM) open-source tools can provide organizations with a cost-effective way to improve their security posture.


SIEM systems typically work by collecting and aggregating event data from multiple sources, such as firewalls, servers, applications, and network devices. They also detect aberrations from the norm, such as uncommon spikes in traffic, botched login attempts, or suspicious activity. In addition, they take appropriate action, such as generating alerts, blocking traffic, or isolating infected devices.

While SIEM systems can be deployed in many different ways, there are two common architectures, including:


Traditional SIEM platforms: These platforms gather and store log data in a centralized location or data store. Traditional SIEM platforms are typically designed to handle large volumes of data, but they can be complex and expensive to implement and maintain.

Modern SIEM architecture based on data lake technology: These platforms use a data lake to store raw data in its original format, making it easier to evaluate and correlate data from multiple sources. However, managing and securing it can also be an uphill task.


Irrespective of the architecture, SIEM systems play a vital role in helping organizations improve their security posture. Provision of real-time analysis of log and event data can also enable SIEM systems to help organizations identify threats and respond to incidents quickly and effectively.

Data Collection

SIEMs collect logs and events from hundreds of organizational systems. Each device generates an event every time something happens, and collects the events into a flat log file or database. The SIEM can collect data in four ways:


  • Via an agent installed on the device (the most common method)
  • By directly connecting to the device using a network protocol or API call
  • By accessing log files directly from storage, typically in Syslog format
  • Via an event streaming protocol like SNMP, Netflow or IPFIX

The SIEM is tasked with collecting data from the devices, standardizing it and saving it in a format that enables analysis.

SIEM Architecture

SIEM architecture is typically divided into three layers:


  1. Data collection layer: This layer is responsible for collecting security data from a variety of sources, such as firewalls, servers, applications, and network devices. Data can be collected in real time or in batches.

  2. Data aggregation and analysis layer: This layer is responsible for aggregating and analyzing the collected data to identify potential security threats. SIEM systems use a variety of techniques to analyze data, including correlation, rule-based detection, and machine learning.

  3. Reporting and alerting layer: This layer is responsible for generating reports and alerts based on the findings of the data analysis layer. Reports can be used to track security trends and to identify areas where security posture can be improved. Alerts can be used to notify security personnel of potential security threats so that they can take action quickly.

Simply put, SIEM systems collect data from a variety of sources, analyze it for potential threats, and generate reports and alerts.


The three layers of SIEM architecture work together to provide a comprehensive security monitoring and management solution.

Operational Best Practices for SIEM

Operational best practices for SIEM are recommendations for how to use a SIEM system effectively and efficiently. These best practices can help organizations to get the most out of their SIEM investment and to improve their overall security posture.

Some common operational best practices for SIEM include:


  • Define clear objectives: What do you want to achieve with your SIEM system? Do you want to detect specific threats? Investigate incidents more quickly? Improve compliance? Once you know your objectives, you can tailor your SIEM configuration and operations to achieve them.
  • Collect the right data: SIEM systems can collect data from a wide variety of sources. However, it’s important to only collect the data that is relevant to your objectives and that you can realistically analyze. Collecting too much data can make it difficult to find the signal in the noise.
  • Use correlation and analytics: SIEM systems are most powerful when they are used to correlate data from different sources and to apply analytics to identify patterns and trends. This can help you to detect threats that would be difficult to find if you were only looking at data from individual sources.
  • Tune your alerts: SIEM systems can generate a lot of alerts, so it’s important to tune them so that you are only notified of the most important events. This will help you to avoid alert fatigue and to focus on the threats that matter most.
  • Monitor your SIEM system: It’s important to monitor your SIEM system regularly to ensure that it is performing properly and that you are not missing any important alerts. You should also review your SIEM configuration regularly to make sure that it is still aligned with your objectives.

In addition to these general best practices, there are a number of specific best practices that organizations can follow to improve their SIEM operations. For example, organizations can:


  • Develop a SIEM incident response plan: This plan should outline the steps that will be taken to investigate and respond to security incidents detected by the SIEM system.
  • Integrate the SIEM system with other security tools: This can help to streamline security operations and to improve the efficiency of incident response.
  • Provide SIEM training to security personnel: It’s important to ensure that security personnel know how to use the SIEM system effectively. This will help them to get the most out of the system and to identify and respond to threats more quickly.

Modern SIEM Solutions

Modern SIEM solutions are increasingly cloud-based and offer a variety of advanced features, including:


  • Machine learning: Modern SIEM solutions use machine learning to identify patterns and anomalies in security data. This can help to detect threats that would be difficult to identify using rule-based detection alone. For example, a machine learning algorithm might be able to detect a new type of malware that has not yet been identified by security researchers.
  • User and entity behavior analytics (UEBA): UEBA is a type of machine learning that analyzes user and entity behavior to identify anomalous activity. This can be helpful for detecting insider threats and other types of attacks that are difficult to detect using traditional methods. For example, a UEBA algorithm might be able to detect a user who is logging in from an unusual location or time.
  • Threat intelligence integration: Modern SIEM solutions can integrate with threat intelligence feeds to get the latest information about known threats. This information can be used to improve the accuracy of SIEM alerts and to identify new threats as they emerge. For example, a SIEM solution might be able to use threat intelligence to identify a new IP address that is known to be associated with a phishing campaign.

Next-gen SIEM

Next-generation SIEM (security information and event management) systems go beyond traditional SIEM capabilities by using machine learning and behavioral profiling to detect anomalies and trends in security data. This allows them to identify threats that would be difficult or impossible to detect using traditional rule-based methods.


Next-generation SIEM systems also typically have the ability to retain and analyze large volumes of historical data. This enables them to detect threats that may have been present in the data for some time, but were not previously identified.


One of the key benefits of next-generation SIEM systems is their ability to perform deep behavioral analysis. This involves analyzing user and entity behavior over time to identify patterns and anomalies. For example, a next-generation SIEM system might be able to detect an employee who is logging in from unusual locations or times, or who is accessing files that they are not authorized to access.


Next-generation SIEM systems are more powerful and versatile than traditional SIEM systems. They can help organizations to detect threats more quickly and accurately, and to improve their overall security posture.

The Log Flow

SIEM systems collect 100% of log data from across an organization, but only a small fraction of that data is relevant for security purposes. SIEM systems use a variety of techniques to filter out noise and identify the most relevant data, including:


Log filtering: SIEM systems can filter out noise from logs by using rules to remove data that is not relevant for security purposes. For example, a SIEM system might be configured to filter out logs from known trusted IP addresses.

Log aggregation: SIEM systems aggregate logs from different sources into a single view. This makes it easier to identify patterns and trends in the data.

Log analysis: SIEM systems use a variety of techniques to analyze logs for security threats. These techniques include correlation, rule-based detection, and machine learning.


Once a SIEM system has identified the most relevant data, it can generate security alerts. Security alerts are notifications that are sent to security personnel to let them know about potential security threats.

SIEM platforms can integrate with a variety of security and organizational data sources, including firewalls, intrusion detection systems, intrusion prevention systems, antivirus software, endpoint detection and response (EDR) software, network devices, servers, applications, cloud platforms, and business systems.

        Cloud Data Access

        Cloud data access is the ability to access data that is stored in the cloud. There are two main types of cloud data access:

        • Public access: Public access means that anyone can access the data. This is typically used for data that is not sensitive, such as public documents.
        • Private access: Private access means that only authorized users can access the data. This is typically used for sensitive data, such as financial information or customer records.

        Several key techniques are involved in restricting access to cloud data. The first step is authentication, which involves confirming a user’s identity using a combination of credentials, often a username and password. Following authentication, authorization is used to decide which specific resources a user is allowed access to.

        These access privileges are frequently defined using role-based access control (RBAC), which ensures that users are only given access to the resources that are pertinent to their tasks or responsibilities. Furthermore, encryption is essential to the security of data in the cloud. It adds an extra layer of security to make sure that the data is still protected from unauthorized access even if authentication or authorization processes are breached. These techniques work together to create a strong framework for controlling and securing cloud data access.

         

        Conclusion

        No matter the size of the firm, cloud data security is a top priority. In a time when data breaches can have serious repercussions, following best practices is essential to protecting your sensitive data. Choosing a reliable cloud service provider known for its strong security features is a crucial first step. Encryption need to be a non-negotiable component of your approach and should be used for data both in transit and at rest. The risk of unauthorized breaches is reduced by implementing least privilege access control, which makes sure that only authorized individuals may access sensitive data.

        It’s vital to routinely check your cloud environment for any unusual activity if you want to keep an eye for any potential threats. Additionally, regularly backing up your data provides a safety net that can come in handy in the event of a data breach, making it easier to restore your data. Last but not least, employees should be educated about best practices for cloud security. They are crucial to maintaining your cloud data’s overall security posture.

                    The Latest Cyber Threats Facing the UK and How to Stay Safe

                    The UK is facing a growing number of cyber threats, from ransomware attacks to data breaches. In 2022, there were over 2.7 million cyber-related frauds in the UK, with a total value of over £2.3 billion. These cyber threats are becoming increasingly sophisticated and can have a devastating impact on individuals, businesses, and the government. To its credit, the National Cyber Security Agency in the UK works diligently to safeguard the nation’s critical infrastructure and protect against cyber threats.

                     

                    The latest cyber threats facing the UK include:

                     

                    • Ransomware: Ransomware is a type of malware that encrypts a victim’s files and demands a ransom payment in order to decrypt them. Ransomware attacks have become increasingly sophisticated, and they can now target businesses of all sizes.
                    • Data breaches: Data breaches are incidents in which sensitive personal or financial data is stolen from a company or organization. Data breaches can have a devastating impact on victims, as they can lead to identity theft, financial fraud, and other problems.
                    • Phishing: Phishing is a type of social engineering attack in which attackers send emails or text messages that appear to be from a legitimate source. The emails or text messages often contain links or attachments that, when clicked, install malware on the victim’s computer.
                    • Business email compromise (BEC): BEC is a type of fraud in which attackers impersonate a legitimate business email address in order to trick victims into sending them money or sensitive information. BEC attacks have become increasingly common in recent years, and they have cost businesses billions of dollars.
