Security Operations as a Managed Service: 24/7 Cloud Protection

Why 24/7 Security Operations Is Necessary

Cyberattacks do not occur during business hours. Ransomware attacks, credential compromise, and lateral movement typically take place outside working hours — when internal security teams are unavailable. For German organizations, the NIS2 directive adds a 72-hour incident reporting obligation and requires continuous risk management.

Security Operations as a Managed Service transfers responsibility for threat detection, compliance monitoring, and incident response to specialized MSPs with a round-the-clock Security Operations Center (SOC).

Key Definitions

Security Operations Center (SOC)

A centralized unit that monitors security events around the clock, analyzes threats, and responds to incidents. In the managed service model, the MSP provides the SOC as an externally delivered service.

Incident Response Playbook

Documented response plan for specific security scenarios (e.g., ransomware, credential compromise, S3 bucket exposure). Defines escalation paths, communication obligations, and containment measures for each incident type.

Security Posture Management

Continuous assessment and improvement of the security posture of a cloud environment. AWS Security Hub aggregates findings from multiple security services and evaluates the overall posture against defined standards (CIS, NIST, BSI C5).

NIS2 (Network and Information Systems Directive 2)

EU directive with mandatory cybersecurity requirements for operators of essential and important services. Requires risk management, supply chain security, incident reporting (72 hours), and regular security audits.

Threat Detection

Automated detection of security threats in cloud environments. AWS GuardDuty analyzes VPC Flow Logs, CloudTrail events, and DNS logs using machine learning to identify anomalous behavior.

Security Operations as a Managed Service: Scope

Incident Response Playbooks: Preparation for the Emergency

Tested playbooks are the core of professional security operations. Storm Reply develops a baseline playbook set for each managed services environment covering at least the following scenarios:

1. Ransomware detection and containment: automated isolation of affected EC2 instances
2. Credential compromise: immediate deactivation of compromised IAM keys, access pattern analysis
3. S3 bucket exposure: configuration correction, analysis of exfiltrated data, GDPR reporting process
4. Lateral movement: network segmentation, containment via Security Groups, forensic analysis
5. Insider threat: CloudTrail forensics, IAM policy review, documented reporting process

All playbooks are tested semi-annually through tabletop exercises and updated to reflect new threat scenarios.

Frequently Asked Questions

What does Security Operations as a Managed Service include?

24/7 threat detection (GuardDuty), continuous compliance monitoring (Security Hub, AWS Config), vulnerability management (Inspector), tested incident response playbooks, and NIS2-compliant reporting processes.

How does Security Operations as a Managed Service meet NIS2 requirements?

NIS2 requires a 72-hour reporting obligation and continuous risk management. Security Operations as a Managed Service implements automated detection, documented escalation paths, and reporting processes that meet NIS2 requirements.

Which AWS services are central to Security Operations as a Managed Service?

Core tools: AWS GuardDuty (threat detection), AWS Security Hub (security posture), AWS Config (compliance), Amazon Detective (incident analysis), AWS CloudTrail (audit logging), Amazon Inspector (vulnerability scanning).

What is the difference between security monitoring and security operations?

Security monitoring is passive — it detects and reports events. Security operations is active — it evaluates events, executes playbooks, communicates with authorities, and closes incidents. MSPs with genuine security operations provide both.

How is GDPR addressed in security operations?

Security logs can contain personal data. The MSP must be contractually bound as a data processor (GDPR Art. 28). Logs must not be transferred outside the EU without adequate protection. Storm Reply operates all security functions in EU regions.
