Cyber Hygiene in SOC for Cybersecurity

This curriculum spans the technical and procedural rigor of a multi-workshop SOC readiness program, covering infrastructure setup, detection engineering, and incident response execution comparable to an internal capability build-out for mid-sized enterprise security operations.

Module 1: Establishing SOC Infrastructure and Operational Baselines

• Selecting between on-premises, cloud-native, or hybrid SIEM deployments based on data residency, latency, and compliance requirements.
• Defining normal network and user behavior baselines using historical logs to reduce false positives in detection rules.
• Implementing centralized log collection from firewalls, endpoints, and cloud workloads with appropriate log retention policies.
• Configuring time synchronization across all SOC systems to ensure accurate event correlation and forensic timelines.
• Designing role-based access controls (RBAC) for SOC analysts to prevent privilege escalation and ensure auditability.
• Documenting standard operating procedures (SOPs) for incident intake, triage, and escalation paths within the SOC.

Module 2: Threat Detection Engineering and Rule Development

• Writing and tuning Sigma rules to detect suspicious PowerShell usage across Windows endpoints without triggering on legitimate automation.
• Developing correlation rules in the SIEM to identify lateral movement via RDP or SMB after initial compromise indicators.
• Integrating threat intelligence feeds (e.g., STIX/TAXII) and filtering for relevance to the organization’s threat model.
• Validating detection logic using purple teaming exercises to confirm detection coverage and reduce blind spots.
• Managing rule lifecycle by deprecating outdated signatures and documenting false positive rates per detection.
• Implementing automated suppression of known benign events to reduce analyst alert fatigue.

Module 3: Endpoint Monitoring and Response Integration

• Deploying EDR agents with disk encryption and memory scanning enabled while assessing performance impact on critical servers.
• Configuring real-time alerting on process injection, suspicious registry modifications, and unsigned binaries execution.
• Establishing containment workflows to isolate compromised endpoints without disrupting business operations.
• Conducting live memory forensics on suspected machines using EDR tools to identify rootkit presence.
• Enforcing application allow-listing policies on high-risk systems and managing exception requests.
• Coordinating endpoint data collection with legal and HR during insider threat investigations.

Module 4: Log Management and Data Integrity Controls

• Classifying log sources by criticality and setting different retention periods for firewall vs. workstation logs.
• Implementing log integrity checks using cryptographic hashing to detect tampering in syslog streams.
• Normalizing log formats from diverse vendors into a common schema for consistent querying.
• Allocating storage resources for high-volume data sources like DNS and proxy logs with compression strategies.
• Restricting write-access to log repositories to prevent unauthorized modification or deletion.
• Validating log source authenticity using mutual TLS or syslog signing to prevent spoofed entries.

Module 5: Incident Response Playbook Execution

• Activating predefined playbooks for ransomware incidents, including network segmentation and backup verification steps.
• Coordinating with IT operations to preserve disk images before reimaging infected systems.
• Documenting chain of custody for forensic evidence collected during incident investigations.
• Executing domain-wide password resets following credential dumping detection, balancing security and usability.
• Initiating communication protocols with legal and PR teams when data exfiltration is confirmed.
• Conducting post-incident timeline reconstruction using correlated logs from multiple sources.

Module 6: Vulnerability Management Integration with SOC

• Prioritizing vulnerability remediation based on exploit availability and asset criticality from SIEM context.
• Automating alerts when unpatched systems exhibit scanning or exploitation attempts in network logs.
• Correlating vulnerability scan results with active threats to justify emergency change requests.
• Coordinating patching windows with operations teams to minimize exposure without causing downtime.
• Tracking known exploited vulnerabilities (KEVs) and adjusting detection rules accordingly.
• Validating patch effectiveness by monitoring for recurrence of exploit-related indicators.

Module 7: Continuous Monitoring and Threat Hunting

• Scheduling proactive hunts for living-off-the-land binaries (LOLBins) using PowerShell and WMI.
• Developing custom queries to identify anomalous outbound DNS queries indicative of data exfiltration.
• Using MITRE ATT&CK mapping to assess coverage gaps in detection capabilities.
• Rotating hunting hypotheses based on recent industry breaches and threat actor TTPs.
• Documenting hunting findings and converting successful techniques into automated detection rules.
• Measuring hunt efficacy through metrics such as mean time to detect (MTTD) and number of undetected threats found.

Module 8: Governance, Compliance, and SOC Maturity Assessment

• Aligning SOC operations with NIST CSF and ISO 27001 controls for audit readiness.
• Conducting quarterly access reviews to remove inactive or overprivileged analyst accounts.
• Performing tabletop exercises to validate incident response coordination with external partners.
• Measuring detection coverage against MITRE ATT&CK to identify under-defended tactics.
• Reporting key SOC metrics (e.g., mean time to acknowledge, false positive rate) to executive leadership.
• Updating policies to reflect changes in regulatory requirements such as SEC disclosure rules or GDPR.
