Security Information and Event Management (SIEM) products and services act, at a basic level, as data aggregation systems. Any SIEM product in the market pulls together log information from a variety of network sources, such as servers and other security tools, to consolidate data that is being monitored all in one place.
Basic understanding of this structure is that you need to add the sources that SIEM product will collect logs must be manual operation. If you need full visibility of what is going on your system, you shouldn’t miss any device or apps. Also, you need buy devices and apps that compatible with your SIEM product.
Today we are moving out from traditional infrastructure and diving in more complex system such as IoT, Sensors and Robots. I can heard that many of you are saying that you have no such things integrated your system yet but trust me one of them, at least, will be hooked up to your system soon and you will be surprised how fast they will be in your system.
When we come to our subject which is SIEM, most SIEMs offer a dashboard where collected data is organized, correlating events together and giving a visual component to the data. SIEMs also store the log data they handle indefinitely, allowing for security teams to dive through the collected data for investigation if need be.
IT teams can receive alerts when threats are detected, and these alerts can be configured to come via the dashboard or through email or text message.
As a part of larger security stacks, SIEMs can be a good way to monitor logs and data from several sources. The alerting abilities of SIEMs are derived from a combination of three detection approaches:
• Correlation of known signatures from third-party threat intelligence against the collected log data
• Implementation of complex searches created by one’s own security team, who can envisage certain types of attack or compliance breach
• Detection from other preventative tools inside the business, which typically also rely on rules and signatures.
This approach leaves a significant gap in defenses where novel or new attacks can operate without being picked up by either preventative tools or the SIEM.
What can Dark Trace do for the gap?
Darktrace never logs in to your servers or applications or devices. It simple monitors RAW network traffic and watch every single device, users. Next thing Darktrace does is that learning everything about system and relationships. It sees everything on Network level and can block everything on network level.
Darktrace replace a SIEM?
We are not comparing same thing here. That is why we can replace SIEM with Darktrace. However, they can work together.
How does Darktrace work with SIEMs?
We just mentioned above that Darktrace can work with your SIEM. Darktrace is compatible with all major SIEMs that support the industry standard Common Event Format (CEF) and Log Event Extended Format (LEEF) including Splunk, QRadar, and ArcSight. Darktrace is able to be configured to fit into SIEM dashboards, so alerts from threats detected by the Enterprise Immune System can be sent to security teams via the SIEM.
This allows security teams that already have SIEMs to add Darktrace to their security stack, without having to change business processes and working practices. While SIEMs can use threat intelligence and correlation for some threat detection, Darktrace can detect a much broader range of threats, both internal and external, and does not rely on rules or signatures.
Darktrace or SIEM?
Well, this is really good question to answer. Sometimes you need just SIEM or Darktrace if you have small budget to invest. If you need to keep long-term historical data, yes SIEM is the best solution for you. If you just need to see what is going on for couple of months and act if needed asap, Darktrace will satisfy your needs.
Also, SIEMs can be a useful tool for data correlation and the convergence of security tools. However, they are fundamentally incapable of performing cyber defense appropriate to today’s threat landscape, as they lack visibility of all network activity, and the capability to identify novel, unknown incidents.
Darktrace can, however, significantly enhance the value of SIEM tools, by inputting log data into the core mathematical engine of the Enterprise Immune System.
Choosing whether or not to employ a SIEM boils down to your preferences, in terms of the structure of your security stack, and desire to use log aggregation for cyber defense. For real-time monitoring and detection of threats within the enterprise, an organization’s first imperative must be to implement an ‘immune system’ technology approach that will keep up with the task, making sense of all data flowing inside the network, whether in the form of log data, or any other network traffic.
