Understanding the SOC (Security Operations Center) and its Role in Protecting IT systems
Cybersecurity is a top concern for businesses, governments, and individuals. With the constant rise of cyber threats, it has become essential to implement robust systems to monitor, detect, and respond effectively to threats and related incidents. This is precisely the role of a SOC, or Security Operations Center. This specialized center ensures the continuous and proactive surveillance of assets with the goal of shielding information systems from cyberattacks.
What is a SOC ?
A SOC is an operational team dedicated to the continuous monitoring and management of an organization's cybersecurity networks and systems. Analysts use specialized cybersecurity tools to detect, analyze, and respond to anomalies and attacks in real-time. They continuously monitor suspicious activities and take necessary actions, such as blocking a malicious IP address, to ensure the security of personal data and protect against intrusions.
The SOC Hierarchy: Understanding Response Levels
SOC operations are often structured into three levels to manage cybersecurity incidents.
SOC Level 1 : Basic Analysis
A Level 1 analyst is responsible for managing basic alerts generated by detection tools. These alerts usually follow a standard playbook, which guides the analyst in taking actions to contain simple attacks.
Level 2 : Responding to Complex Attacks
When a threat exceeds the handling expertise of Level 1 analysts, it is escalated to Level 2. Level 2 analysts have greater expertise and have the ability to analyze attacks in greater depth and determine the appropriate actions.
Level 3 : Advanced Expertise
Level 3 corresponds to senior-level expertise capable of handling highly complex attacks. These analysts perform in-depth analyses, replicate attack scenarios, conduct cybersecurity tests, and find specific solutions.
Limitations of the Traditional 3-Level SOC Model
Despite the effectiveness of a classic SOC, limitations arise with highly complex attacks, such as zero-day vulnerabilities. A Level 3 analyst may not have the expertise to handle such a situation, requiring them to engage the technology provider used by the SOC (e.g., the SIEM, IDS/IPS, EDR, etc.). However, waiting for a vendor's response can take time, leaving gaps in the protection of the company’s personal data, which can have disastrous consequences.
Why Traditional SOCs Are No Longer Sufficient?
Given the increasing sophistication of cyber threats, it is becoming essential to integrate more advanced skills than those available at Level 3. AI and cybersecurity are playing an increasingly important role in this evolution, enabling better threat detection, faster reaction times and the optimization of cybersecurity tools.
The Need for a Level 4 SOC
At Streamscan, we have developed a Level 4 SOC to address these challenges. This level of sophistication enables our analysts to handle the type of advanced attacks that a traditional SOC could not manage effectively.
Streamscan : The Level 4 SOC and its Advantages
Our SOC stands out because, beyond just monitoring an organization's network, we actively create detection signatures and AI models which allow us to identify unknown or brand-new attacks and their variants. These signatures and AI models can be directly integrated into the cybersecurity technologies that we offer to our clients.
Creating Signatures and AI Models
Level 4 SOC analysts at Streamscan don’t merely respond to detected threats. They go further by creating signatures for new threats or using artificial intelligence to analyze and detect attack variants that were previously unidentified. This process is vital for preventing cyberattacks, especially those driven by AI (using AI to generate new threats).
A Different Proactivity and Methodology
The mindset of a Level 4 SOC analyst is rooted in proactivity and the anticipation of threats. Unlike a traditional SOC, which can be reactive and limited by available tools and knowledge, a Level 4 SOC constantly seeks to improve systems and evolve. Their goal is to detect unprecedented attacks, including those arising from sophisticated ransomware or phishing schemes.
Why Choose a Level 4 SOC?
Protection Against Complex Cyberattacks
Cyber threats are evolving rapidly and constantly, and the growing use of AI in cyberattacks makes detection more difficult. Traditional SOCs struggle to keep the pace. However, with a Level 4 SOC, analysis takes place in a controlled sandbox environment, where complex attack scenarios are tested in real-time.
Better Detection of Attack Variants
Level 4 analysts are able to detect new variants of attacks by reproducing scenarios in a secure environment. This proactive methodology is essential for ensuring top-tier cybersecurity.
Advanced Cybersecurity Solutions
The integration of AI in cybersecurity defences allows the creation of detection models based on machine learning or deep learning algorithms, significantly boosting our ability to prevent unprecedented cyberattacks.
Client Success Story: Zero-Day Malware Protection
When a zero-day malware was detected at one of our clients, our Level 4 analyst performed reverse engineering of the malicious code. They then reproduced the attack in a secure sandbox environment, and developed a specific signature. This signature was deployed to block both the original attack and its variants within the client's existing security tools. This proactive approach successfully protected the company's sensitive data and averted potential damage to their IT systems.
The Future of Cybersecurity with Streamscan
In the face of increasingly complex cyber threats and AI-driven attacks, it is essential for businesses to adopt advanced cybersecurity tools and rely on expert analyst teams. With a Level 4 SOC, Streamscan offers rapid and effective responses, ensuring network security and the protection of assets and personal data. The future of cybersecurity lies in this evolution, and with Streamscan, you are ready to face tomorrow’s challenges.
