Managed security services

NTT Ltd. divides its managed security services (MSS) into seven categories:

  • Managed detection and response: Provides network and endpoint visibility, advanced analytics using machine learning and threat intelligence, "analyst-driven" attack investigation and disruption, incident reporting, compromised host isolation, and event dashboards[5]
  • Threat detection services: Provides threat detection services based upon the service package selected: Standard or Enhanced. Both packages offer 24/7 detection with updates, analytics, and reports from internal intelligence investigations and modeling. Enhanced adds packet capture data, malware execution reports, host recordings, incident investigation, threat hunting, and more.[6]
  • Enterprise security monitoring: Provides enterprise security monitoring based upon the service package selected: Standard or Enhanced. Both packages offer 24/7 monitoring with analyst-reviewed incident reports, customizable monitoring and reporting schemes, and customizable web portals. Enhanced adds wider global threat intelligence, device support, and optional raw log search.[7]
  • Security device management: Provides security device management based upon the service package selected: Standard or Enhanced. Both packages offer health and availability monitoring, improvement, and recommendation; incident generation, diagnosis, and reporting; capacity planning, monitoring, reporting, and recommendation; asset tracking and reporting; service request management and information fulfillment; and problem management. Enhanced adds multiple change implementations, incident resolutions, and more.[8]
  • Security operation center (SOC) as a service: Provides 24/7 staffed SOC center with incident monitoring and alerts; SIEM platform management and configuration; custom use-cases, dashboards, and reports; NTT's Cyber Threat Sensor; compliance monitoring, notification, and reporting; custom playbooks; and incident lifecycle support.[9]
  • Web application firewall (WAF) as a service: Provides WAF configuration and protection services based upon the service package selected: Standard or Enhanced. Standard provides WAF safeguarding with full web server visibility, 24/7 access to the NTT SOC for support and engineering, PCI DSS compliance reporting, and enhanced risk management. The Enhanced package provides the same and adds advanced incident detection and analytics, threat intelligence, threat hunting, full security incident reports with remediation recommendations, and business/regulatory compliance reporting.[10]
