SIEM Technology And SOC Team

Why should use SIEM Technology in SOC Teams?
In this article, I will discuss about why we should use SIEM Technology in SOC Teams as I’ve learned. Before starting about SIEM Technology, I would like to introduce some current challenges faced in traditional Security Operation Centers (SOC).
‍‍‍‍‍‍ 
SOC team is known as a team which is monitoring the whole network infrastructure in organizations. SOC teams run in 24 hours to detect every important security alert in network infra and take actions as soon as an incident happens.
‍‍‍‍‍‍ 
 Traditional SOC Challenges
‍‍‍‍‍‍ 
 Receiving Volumes of Security Alerts
With the snowballing number of security alerts being received, most of the time of a security analyst is being consumed by sorting the priority of every security alert instead of directly knowing the sophisticated one and taking action as soon as possible. Therefore, this time-consuming process leads to human error that they often miss important security alerts and detect alerts after network damage has occurred.
‍‍‍‍‍‍ 
 Lack of Centralized Management
A typical SOC team has to use many security tools. There is no centralized management system to manage different data sources coming from each individual security tool as a single platform.
‍‍‍‍‍‍ 
 Legal and Regulatory Compliance
I suppose you have already known about compliances in Compliance Part 1 article. When organizations validate PCIDSS, HIPAA and GDPR compliances, it is a mandatory process for SOC team to provide an incident report with the required parameters in compliant tasks. In the case of GDPR compliant task, SOC team must provide an incident report within 72 hours of breach. It is difficult for traditional SOC teams to provide rapid incident report.
‍‍‍‍‍‍ 
These facts I described above are main challenges of traditional SOC team.
‍‍‍‍‍‍ 
Let’s continue to learn which excessive features of SIEM technology can provide other than it can eliminate above challenges to help traditional SOC team.
‍‍‍‍‍‍ 
 SIEM Technology (Security Information and Event Management)
It can be defined as SIEM technology is a main requirement for SOC team. Security Information and Event Management (SIEM) is the system that centralizes and analyzes the data, allowing reporting, notification and response to security events based on correlation and analysis capabilities.‍‍‍‍‍‍ If you feel complicated about SIEM definition, I will explain these meanings one by one as SIEM provided features.
‍‍‍‍‍‍ 
 SIEM Provided Features
‍‍‍‍‍‍ 
🔹 Centralized Logging and Real Time Monitoring
SIEM can eliminate monitoring many security tools individually in traditional SOC. SIEM can give Centralized Management feature that can manage summarized logs from different data sources such as Firewalls, Endpoints, Antivirus, Routers, Switches, Servers and etc., as a single platform. This centralized management can be provided in real-time.
‍‍‍‍‍‍ 
🔹 Rapid Incident Response
SIEM technology can incorporate with current firewalls like F5, Checkpoint, Palo Alto, Cisco Firepower and other firewalls. In case of making Brute Force attack to our organization, as soon as SIEM system detects this attack behavior, it forwards attack alert to corporate firewalls and block the attacker IP. Therefore, SIEM can quickly provide incident response feature.
‍‍‍‍‍‍ 
🔹 Log Correlation Capability
Next one is Log Correlation capability. This feature can help the most difficult forensic process of traditional SOC to be easy. Let’s assume that our organization has been accidently attacked. By summarizing log types from different data sources into a meaningful data, SIEM Technology helps SOC teams to track attack-traffic whether this traffic has been passed through the firewall or the AD server and also help finding track if core switches, critical servers and endpoints have been affected. This feature is called Log Correlation.
‍‍‍‍‍‍ 
🔹 Compliance Focus
As well as SIEM can provide Log Correlation and Incident Response feature, it also makes sure one of compliant tasks, Incident Reporting. Nowadays, every single organization validating compliance has already used SIEM Technology in their network infrastructure.‍‍‍‍‍‍
‍‍‍‍‍‍ 
 Why should use SIEM Technology in SOC Teams?
By comparing the challenges of traditional SOC to the strength of SIEM technology, it can be guessed that SIEM technology will become as one of the next generation SOC tools. So, it’s time to start to use SIEM Technology that can provide essential requirements like Centralized Management, Rapid Incident Responding, Log Correlation and Compliance Focus while none of the network monitoring tools is capable of these features.
