Security Operations (SecOps)

---

Security operations (SecOps) is a holistic approach to security that brings people, processes, and technology together to streamline cyberthreat detection, investigation, and response.¹

• SecOps teams
  • identify and address security risks using a repeatable workflow
    • includes:
      • alert intake
      • triage and investigation
      • escalation
      • resolution
      • and eradication and recovery
  • embrace a Zero Trust approach
    • never trust, always verify
    • Zero Trust Architecture (ZTA)

Benefits

• Increases visibility into threats across the entire environment
  • centralized visibility + automated tools
• Reduces breach impacts
  • faster incident detection, triage, and response
  • strengthens data loss prevention efforts
• Unifies IT and security teams
• Improves compliance and governance
• Scales defense with advanced tooling
• Reduces costs
  • proactively prevent breaches and other incidents

Common Challenges

• high alert volume
• talent shortages
• siloed tools
• lack of visibility

Core Components

• Continuous security operations center (SOC) monitoring
• Threat detection and analytics
• Threat hunting
  • proactively hunt for unusual behavior, policy violations, or early IoCs across networks, identities, endpoints, and applications
• Incident response
• Threat intelligence
  • collect and analyze threat intel about known adversaries, vulnerabilities, malware, and active campaigns
• Advanced tools:
  • SIEM
  • SOAR
  • XDR
  • Cloud security solutions

Day-to-Day Work

• general workflow to identity and address security risk:
  1. Alert intake
  2. Triage and investigation
  3. Escalation
  4. Resolution
  5. Eradication and Recovery
• Incident response phases:
  1. Preparation
  2. Detection
  3. Containment
  4. Eradication
  5. Recovery
• Successful program combines human expertise with AI-assisted tools and repeatable, automated workflows
• Security engineers and security analysts must work together to plan and create a multilayered security model
  • engineer → creates robust security architecture
  • analyst → monitors and responds to threats within the architecture
• Proactive activities:
  • Threat hunting
    • analysts deliberately search for threats
  • Vulnerability management
    • find and address vulns before threat actor can exploit
  • Security awareness and training
    • educate users about common tactics cybercriminals use
    • create a security-first culture

Build a Strong SecOps Program

1. Implement Zero Trust Architecture
2. Automate repetitive tasks
3. Conduct regular tabletop exercises
4. Continuously tune detection rules and threat intel sources
5. Measure and optimize KPIs
   • MTTD + MTTR
