A Security Information and Event Management (SIEM) system gives security managers a holistic overview of multiple security systems.
Explore the latest SIEM solutions offering advanced threat detection, compliance management, and real-time monitoring capabilities to enhance your cybersecurity posture.
SIEM tools centrally store and analyze log from different locations in order to spot patterns and trends that might signal an emerging security threat or attack. SIEM security combines a security information management (SIM) system with security event management (SEM) to form a single SIEM software solution. In this way, SIEM blends the best of event management tools with security event and incident management technologies.
There are multiple SIEM vendors competing in the market today. PeerSpot members offer a number of recommendations for those considering SIEM solutions.
Keep in mind, while SIEM is used for detecting security threats and triggers the alerts, a SOAR solution is needed to act on these alerts.
One phrase that comes up repeatedly in PeerSpot dialogues about SIEM products is “real time.” According to reviewers, SIEM technology should possess real-time threat analysis and reporting capabilities. Solutions should offer real time security related logs and incident reporting. Reports need to specify possible risks and damage to infrastructure. A SIEM tool should ideally provide real time gathering of logs and Log Correlation. Notification event Triggering and the availability special Event Collectors with different environment is viewed as a most important criterion.
Some PeerSpot members stress the importance of SIEM being able to combine information from multiple sources. The solution has to be capable of intelligent queries on these combined sources. Put another way, SIEM must offer compatibility with diverse security data sources and be able to adapt to new or unknown sources. Then, the SIEM solution should perform multilevel correlation on those sources of data.
Efficient use is important. A SIEM tool must be easy to deploy, configure and use. SIEM can be more effective if it integrates with Identity and Access Management. Alerting and workflow integration adds to administrative efficiency.
Specific features recommended include packet analysis, audit trail creation, threat intelligence and search. Users encourage potential buyers to have confidence in the power of a SIEM solution’s search performance and the performance of its threat intelligence engine. The solution should be capable of parsing any log format.
As with any enterprise tech solution, it’s important to spend time doing your research and POC, so that you know that you’re spending on the right product. We sifted through some of our users’ answers to summarize some of the best tips.
Before starting to evaluate solutions, It’s important to define what you want to accomplish with a SIEM. Marty Baron says, “Every SIEM has different strengths and weaknesses so you need to know what is most important to you in terms of goals, so you don’t waste time looking at something that can’t do the thing you need it to do.”
As one of your users says, “Review a finite number of products, otherwise you’ll never finish”. Although it’s important to spend time doing due diligence, you need to get to the point of implementation. If you have too many options, it will take too long to make a decision. Users suggest making a shortlist of options that meet your technical requirements, speak to your goal, and match your budget
Once you’ve narrowed down your options, it’s time to trial the shortlisted products. Users recommend putting a framework in place to guide the POC. This way, you can evaluate your options systematically.
One user, DAX Paulino, suggests “creat[ing] a checklist of features that you need, from the basic (i.e. interactive dashboards, ease of integration, Threat Intelligence), to the more advanced (i.e. Automated response, Behavior Analytics, etc.). Give each item on your checklist a score so that you can weigh in on each item as a measure of your decision. Don’t forget to factor in usability and support.”
