Initially, Security Information and Event Management (SIEM) solutions were readily adopted because of their capability to provide actionable insights into the deep corners of an organization’s network. Legacy SIEM systems helped in understanding when and where security incidents are happening in real-time. Soon enough, these SIEM systems faced an avalanche of false positives, and they required a dedicated team to filter out irrelevant alerts.
Following this, we saw the emergence of next-generation SIEM solutions that provide functionalities and features that were not available with legacy or first-generation SIEM solutions. In this article, we demonstrate the features of a modern, next-gen SIEM solution.
Like the previous years, 2019 also witnessed the surge in data breaches and cyber-attacks. However, organizations having SIEM or/and SOAR system in place were better than those using traditional security tools. The cyber-attacks in 2019 were mostly related to financial crimes, supply chain attacks, phishing exploits, state-sponsored attacks, Grid attacks, health sector attacks, and attacks on IoT devices. Cybersecurity skills shortage was also one of the major concerns in 2019.
In this first part of the article, we will take a look at how SIEM and SOAR tools were helping organizations in 2019 to get rid of cyber-attacks.
Undoubtedly, today’s cyber threats are very fast and sophisticated. Even their detection and prevention is no longer an easy task. To prevent organizations from being a victim of cyber threats and attacks, a proactive cybersecurity approach must be used. That is the reason the Cyber Threat Intelligence (CTI) framework comes into place. CTI has become a critical tool for organizations trying to protect their networks and infrastructure.
Use Case 6: SIEM Security with Artificial Intelligence
SIEM security that is equipped with Artificial Intelligence (AI) and user behavior analytics can deal with internal threats. AI capabilities in SIEM help security professionals to automate tasks that are otherwise manual and repetitive. Doing so can also help to swiftly detect threats and suspicious activities in network traffic and event logs.
6. Responding to Threat or Vulnerability
In the previous steps, analysts have gathered enough data to answer their hypothesis. Two types of situations can occur. Either the real threat is found or the vulnerability is detected. In both cases, analysts action is necessary. The analysts must respond immediately when a real threat is identified. However, if there is any vulnerability, they should also resolve this before it becomes a really big nightmare.
