Incident Response

Turning Attacks into Resilience

From tracing intrusion paths to a recurrence prevention roadmap. Through threat intelligence-based incident response, we identify the causes of incidents and redesign the security framework.

Engineering Cyber Resilience

Incident Response supports a response strategy that extends beyond containment to preventing recurrence and strengthening your security posture.

Market Needs & Client Challenges

Unclear Incidents,
Urgent Response Decisions

Incident Scope Unclear, Decisions Can't Wait

Unclear Incident Scope & Response Priorities

Signs of a suspected hack are visible, but it is not easy to quickly judge how far the compromise extends and what to respond to first.
Wrong actions in the early stages of an incident can lead to the destruction of evidence and the spread of damage, so a framework that quickly grasps the scope of the incident and response priorities is needed.

Disrupted Operations, Critical Recovery Decisions

When a service is disrupted by ransomware or a system breach, the timing and method of recovery must be decided quickly, but there is significant concern about reinfection and further damage.
For safe service restoration, a recovery strategy based on technical grounds—removing intrusion paths, verifying backup integrity, and judging recovery priorities—is needed.

Evidence Gaps & Regulatory Pressure

The legal reporting deadline approaches, but securing valid evidence, estimating the scope of the leak, and organizing it into materials for regulator response is not easy.
Compliance risk can only be addressed by clearly proving the technical facts while maintaining evidence integrity in accordance with digital forensic principles.

An Incident Response Framework Spanning Containment, Recovery, and Forensics

What Is Incident Response?

Incident response is a strategic crisis response service that carries out everything from immediately after a security incident occurs through root-cause analysis, confirmation of the damage scope, threat removal, recovery support, and recurrence prevention.

Respond Fast. Remove Threats.

Immediately upon receiving a report, it activates isolation and blocking procedures to reduce the risks of infrastructure contamination and data leaks, and tracks the hidden privileges and backdoors left by attackers to block the possibility of re-intrusion.

Recover with Confidence

By establishing recovery priorities, it restores core services and minimizes the economic losses and decline in brand trust caused by downtime. It verifies whether backup data is contaminated to determine a safe point for recovery and reduce the risk of reinfection.

Evidence Preservation
& Governance Improvement

For incidents that require reporting to relevant agencies within 72 hours, it secures integrity evidence and technical analysis materials in accordance with digital forensic principles, and builds a strengthened security framework by remediating potential vulnerabilities based on the root-cause analysis.

Forensic Analysis & Attribution

Analyzing malware, logs, and system traces to precisely grasp the cause of the compromise and the attack path
Comparing attack techniques and TTPs against threat intelligence to analyze the attack's perpetrators and the possibility of similar attacks

Exfiltration Tracking & Assessment

Checking hidden channel data such as the dark web and deep web, and signs of external leaks, to determine whether internal confidential information has been leaked and its potential for sale
Back-tracing intrusion paths and vulnerabilities to identify the additional scope of impact, including affected endpoints, accounts, and systems

Mitigation & Active Eradication

Blocking the spread of attacker tools and malware and controlling the cascading intrusion paths leading to core systems, accounts, and data
Removing dormant tools, backdoors, and residual malicious elements to minimize the possibility of re-intrusion and further damage

Tactical Profiling & Security Improvement

Analyzing attack techniques and behavioral patterns based on incident data to derive detection criteria for similar attacks
Reflecting the latest threat intelligence to improve the infrastructure security framework and prepare for further intrusion attempts

Turn Incident Evidence into Response Strategy

Clearly identifying the cause of an incident and establishing a response strategy requires comprehensively analyzing attack techniques, the perpetrators, the potential for leaks, and re-intrusion paths—beyond simple technical analysis. Drawing on a proven track record in international cybercrime tracking, S2W precisely identifies incident causes and establishes crisis response strategies.

Redesign Security Against Repeat Attacks

Service restoration alone does not end incident response. Only by removing the cause of intrusion and residual threats and controlling re-intrusion paths can the recurrence of the same type of incident be reduced. Based on incident analysis results, S2W examines the security structure of the customer's environment and presents a mid-to-long-term security roadmap to prevent recurrence.
