What is a SIEM solution? How SIEM works and Architecture? Relative Security

Security Information and Event Management or SIEM tools are essential for identifying cyber attacks.

What is Security Information and Event Management (SIEM)?

What is Security Information Management (SIM)?

Security Information Management (SIM) is the collection, monitoring, and analysis of security-related data from computer logs.

What is Security Event Management (SEM)?

Security Event Management (SEM) is the practice of network event management including real-time threat analysis, visualization, and incident response.

SIEM vs SIM vs SEM – what’s the difference?

SIEM, SIM, and SEM are often used interchangeably but there are some key differences.

SIEM capabilities

SIEM’s basic capabilities are as follows:

Log Collection

Normalization – Collecting logs and normalizing them into a standard format

Notifications and Alerts Notifying the user when security threats are identified

Security Incident Detection

Threat response workflow Workflow for handling past security events

SIEM records data from across a users’ internal network of tools and identifies potential issues and attacks. The system operates under a statistical model to analyze log entries. SIEM distributes collection agents and recalls data from the network, devices, servers, and firewalls.
All this information is then passed to a management console where it can be analyzed to address emerging threats. It’s not uncommon for advanced SIEM systems to use automated responses, entity behavior analytics and security orchestration. This ensures that vulnerabilities between cybersecurity tools can be monitored and addressed by SIEM technology.
Once the necessary information reaches the management console, it is then viewed by a data analyst who can provide feedback on the overall process. This is important because feedback helps to educate the SIEM system in terms of machine learning and increasing its familiarity with the surrounding environment.
Once the SIEM software system identifies a threat, it then communicates with other security systems on the device to stop the unwanted activity. The collaborative nature of SIEM systems makes them a popular enterprise-scale solution. However, the rise of pervasive cyber threats has made many small- and mid-sized businesses consider the merits of a SIEM system as well.
This change has been relatively recent because of the substantial costs of SIEM adoption. Not only must you pay a sizeable amount for the system itself; you need to allocate one or two members of staff to oversee it. As a result, smaller organizations have been less enthusiastic about SIEM adoption. But that has begun to change as SMEs can outsource to managed service providers.

Why is SIEM Important?

SIEM has become a core security component of modern organizations. The main reason is that every user or tracker leaves behind a virtual trail in a network’s log data. SIEM systems are designed to use this log data in order to generate insight into past attacks and events. A SIEM system not only identifies that an attack has happened, but allows you to see how and why it happened as well.
As organizations update and upscale to increasingly complex IT infrastructures, SIEM has become even more critical in recent years. Contrary to popular belief, firewalls and antivirus packages are not enough to protect a network in its entirety. Zero-day attacks can still penetrate a system’s defenses even with these security measures in place.
SIEM addresses this problem by detecting attack activity and assessing it against past behavior on the network. A SIEM system has the ability to distinguish between legitimate use and a malicious attack. This helps to increase a system’s incident protection and avoid damage to systems and virtual property.
The use of SIEM also helps companies to comply with a variety of industry cyber management regulations. Log management is the industry-standard method of auditing activity on an IT network. SIEM systems provide the best way to meet this regulatory requirement and provide transparency over logs in order to generate clear insights and improvements.

The essential features of SIEM Tools

Not all SIEM systems are built the same. As a result, there is no one-size-fits-all. A SIEM solution that’s right for one company may be incomplete to another. In this section, we break down the core features needed for a SIEM system.

Log Data Management As mentioned above, log data management is a core component of any enterprise-scale SIEM system. A SIEM system needs to pool log info from a variety of different data sources, each with their own way of categorizing and recording data. When looking for a SIEM system, you want one that has the ability to normalize data effectively (you might need a third-party program if your SIEM system isn’t managing disparate log data well).
Once the data is normalized, it is then quantified and compared against previously recorded data. The SIEM system can then recognize patterns of malicious behavior and raise notifications to alert the user to take action. This data can then be searched by an analyst who can define new criteria for future alerts. This helps to develop the system’s defenses against new threats.

Compliance Reporting

In terms of convenience and regulatory requirements, having a SIEM with extensive compliance reporting features is very important. In general, most SIEM systems have some kind of onboard report generating system that will help you to conform to your compliance requirements.
The source of requirements of the standards that you need to conform to will be a major influence on which SIEM system you install. If your security standards are dictated by customer contracts, you don’t have much leeway on which SIEM system you choose — if it doesn’t support the required standard, then it won’t be any you’re used to.
You may be required to demonstrate compliance to PCI DSS, FISMA, FERPA, HIPAA, SOX, ISO, NCUA, GLBA, NERC CIP, GPG13, DISA STIG or one of many other industry standards.

Threat Intelligence

If a breach or attack occurs, you can generate a report that details how it happened extensively. You can then use this data to refine internal processes and make adjustments to your network infrastructure to make sure it doesn’t happen again. This uses SIEM technology keeps your network infrastructure evolving to address new threats.

Fine Tuning Alert Conditions Having the ability to set the criteria for future security alerts is essential for maintaining an effective SIEM system through threat intelligence. Refining alerts is the main way you keep your SIEM system updated against new threats. Innovative cyber-attacks are emerging every day, so using a system that’s designed to add new security alerts stops you from getting left behind.
You also want to make sure that you find a SIEM software platform that can limit the number of security alerts you receive. If you’re inundated with alerts your team is going to be unable to address security concerns in a timely manner. Without fining tuning alerts you’re going to be subjected to sifting through masses of events from firewalls to intrusion logs.

Dashboard An extensive SIEM system is no good if you have a poor dashboard behind it. Having a dashboard with a simple user interface makes it much easier to identify threats. In practice, you’re looking for a dashboard with visualization. Straight away this allows your analyst to spot if any anomalies are occurring on the display. Ideally, you want a SIEM system that can be configured to show specific event data.

The best SIEM tools

Before choosing a SIEM tool, it’s important to evaluate your goals. For example, if you’re looking for a SIEM tool to meet regulatory requirements, generating reports will be one of your foremost priorities.
On the other hand, if you want to use a SIEM system to stay protected against emerging attacks, you need one with high functioning normalization and extensive user-defined notification facilities. Below we take a look at some of the best SIEM tools on the market.

Our methodology for selecting a SIEM toolWe reviewed the SIEM market and analyzed tools based on the following criteria:

A system that gathers both log messages and live traffic data

A log file management module

Data analysis utilities

The ability to report to data protection standards

Easy to install with an easy-to-use interface

A trial period for assessment

The right balance between functionality and value for money
