Ransomware Threat Mitigation and Cybersecurity Resilience Enhancement for a North American Manufacturing Corporation

Needs And Requirements:

The client, following a recent gap assessment, encountered irregularities on their network and issues with Microsoft AD connectivity. Unusually high traffic from a specific server, flagged by their firewall, raised concerns about a potential cyber-attack, prompting an immediate need for incident response services.

Main Challenges:

Lacking Comprehensive Cybersecurity Solutions: The absence of Security Information and Event Management (SIEM), Endpoint Detection and Response (EDR), and Network Detection and Response (NDR) solutions posed significant challenges in maintaining a robust cybersecurity posture. Without these key solutions, identifying the precise timing of security incidents became difficult, forcing the organization to rely solely on firewall logs for analysis.

Incident Identification and Analysis: The organization lacked visibility into potential threats beyond firewall logs, necessitating thorough investigation and analysis.

Solution:

Cyber Resilience & Incident Response Hitachi Cyber, swiftly initiated a forensic analysis of the affected server upon detecting irregular network traffic. Experienced cybersecurity analysts meticulously investigated the anomalies to uncover the root cause, confirming the presence of ransomware. Subsequent containment and mitigation efforts, including system isolation and endpoint security controls deployment, mitigated the threat effectively. Comprehensive remediation suggestions were provided, emphasizing network defense strengthening and employee cybersecurity awareness enhancement through tailored training programs.

Outcomes:

Successful identification and mitigation of the ransomware threat reinforced the organization’s cybersecurity resilience. Enhanced incident response capabilities and proactive security measures ensure readiness to tackle future cyber threats effectively, upholding the organization’s commitment to robust cybersecurity practices.

Next Steps:

Hitachi Cyber is on the verge of launching Managed Detection and Response services, enriched with three pivotal capabilities: SIEM, NDR, and EDR. The amalgamation of these solutions is set to strengthen the organization’s current security infrastructure. This strategic enhancement is designed to expedite the detection of potential threats and streamline response actions. Consequently, this will fortify the organization’s cybersecurity stance, ensuring it remains robust and resilient.
