SOC Chronicles: What Has
Changed and What Has Stayed the
Same?

Who am I?
Outline
● SOC refresher for 2020
● WHY | WHAT | HOW
○ Why MODERN SOC?
○ What modern SOC is?
○ What modern SOC isn’t?
○ How to evolve your SOC to this?
● What to expect next?
○ Ah, and “Is SOC dead?” :-)
“A security operations center provides centralized
and consolidated cybersecurity incident prevention,
detection and response capabilities.” -- Gartner
SOC is first a TEAM. Next a PROCESS. And it uses
TECHNOLOGY too.
What is a SOC?
Why Modern SOC?
Force 1: Expanding attack surface
More things to secure...
Force 2: Security talent shortage
More things to secure than people...
Force 3: Too many alerts from too many tools
More things to secure that all scream for attention…
(source)
Modern SOC
● Teams is organized by skill, not rigid level
● Process structures around threats, not alerts
● Threat hunting covers for cases where alerts never
appear
● Multiple visibility approaches, not just logs
● Automation via SOAR works as a force multiplier
● Deeper testing and coverage analysis
● Threat intelligence is consumed and created
● Elegantly uses third party services
NOT Modern SOC
● Inspired by IT helpdesk philosophy
● Treats incidents as rare and abnormal
● Focuses on alert pipeline, and pairs alerts to analysts
● Centered on a SIEM (SOC = SIEM analyst team)
● Has walls between alert handlers and alert tuners
● Threat intelligence is sometimes consumed
● Shallow metrics on handling time
Highlights of Modern SOC: People
Highlights of Modern SOC: Tools
● Logs (such as via SIEM)
● Network data (such as via NDR)
● Endpoint data (such as via EDR)
Other data (deception, RASP, etc)
Highlights of Modern SOC: Processes
Highlights of Modern SOC: Detection Engineering
● Detection content versioning
● Proper “QA” for detection content”
● Content (code) reuse and modularity
● Cross-vendor and cross-tool content
● Metrics, coverage and improvement
P.S. This is not about programming as such
Highlights of Modern SOC: “Help”
“Every modern SOC is a hybrid SOC” -- Anton Chuvakin [source]
THIS OUTSOURCES WELL
- Deeper malware analysis
- Threat intelligence
- SIEM, EDR and other tool
management and tuning
- SOC tool tuning and use case
analysis
- Managed threat hunting
THIS OUTSOURCES BADLY
- Remediation of threats
- Full cycle of incident response
- Insider threat detection
- Business- and application-specific
threat detection
THIS DOES NOT OUTSOURCES AT ALL
- Accountability for security success
- Governance of security program
Recommendations
● Sure, handle alerts, but be aware that this is not your entire
world
● Make analysts and engineers friends; no walls in SOC
● Hire skills, not levels
● Automate routines, and keep fuzzy tasks for people (hunt)
● Prepare to trust 3rd parties with some tasks
● Keep your SIEM, but be aware that SOC visibility is broader
than logs
● Ah, and read https://medium.com/anton-on-security :-)
Intermission: Is SOC Dead?
● SOC as a CROWDED
ROOM may be dead…
● SOC as a detection and
response team is NOT
dead.
● Can it ever be dead? Well,
now, this is a topic for
another time …

SOCstock 2020 Groovy SOC Tunes aka Modern SOC Trends

  • 1. Groovy SOC Tunes SOC Chronicles: What Has Changed and What Has Stayed the Same? Dr. Anton Chuvakin Google Cloud Security / Chronicle; ex-Gartner @anton_chuvakin medium.com/anton-on-security
  • 3. Outline ● SOC refresher for 2020 ● WHY | WHAT | HOW ○ Why MODERN SOC? ○ What modern SOC is? ○ What modern SOC isn’t? ○ How to evolve your SOC to this? ● What to expect next? ○ Ah, and “Is SOC dead?” :-)
  • 4. “A security operations center provides centralized and consolidated cybersecurity incident prevention, detection and response capabilities.” -- Gartner SOC is first a TEAM. Next a PROCESS. And it uses TECHNOLOGY too. What is a SOC?
  • 5. Why Modern SOC? Force 1: Expanding attack surface More things to secure... Force 2: Security talent shortage More things to secure than people... Force 3: Too many alerts from too many tools More things to secure that all scream for attention… (source)
  • 6. Modern SOC ● Teams is organized by skill, not rigid level ● Process structures around threats, not alerts ● Threat hunting covers for cases where alerts never appear ● Multiple visibility approaches, not just logs ● Automation via SOAR works as a force multiplier ● Deeper testing and coverage analysis ● Threat intelligence is consumed and created ● Elegantly uses third party services
  • 7. NOT Modern SOC ● Inspired by IT helpdesk philosophy ● Treats incidents as rare and abnormal ● Focuses on alert pipeline, and pairs alerts to analysts ● Centered on a SIEM (SOC = SIEM analyst team) ● Has walls between alert handlers and alert tuners ● Threat intelligence is sometimes consumed ● Shallow metrics on handling time
  • 8. Highlights of Modern SOC: People
  • 9. Highlights of Modern SOC: Tools ● Logs (such as via SIEM) ● Network data (such as via NDR) ● Endpoint data (such as via EDR) Other data (deception, RASP, etc)
  • 10. Highlights of Modern SOC: Processes
  • 11. Highlights of Modern SOC: Detection Engineering ● Detection content versioning ● Proper “QA” for detection content” ● Content (code) reuse and modularity ● Cross-vendor and cross-tool content ● Metrics, coverage and improvement P.S. This is not about programming as such
  • 12. Highlights of Modern SOC: “Help” “Every modern SOC is a hybrid SOC” -- Anton Chuvakin [source] THIS OUTSOURCES WELL - Deeper malware analysis - Threat intelligence - SIEM, EDR and other tool management and tuning - SOC tool tuning and use case analysis - Managed threat hunting THIS OUTSOURCES BADLY - Remediation of threats - Full cycle of incident response - Insider threat detection - Business- and application-specific threat detection THIS DOES NOT OUTSOURCES AT ALL - Accountability for security success - Governance of security program
  • 13. Recommendations ● Sure, handle alerts, but be aware that this is not your entire world ● Make analysts and engineers friends; no walls in SOC ● Hire skills, not levels ● Automate routines, and keep fuzzy tasks for people (hunt) ● Prepare to trust 3rd parties with some tasks ● Keep your SIEM, but be aware that SOC visibility is broader than logs ● Ah, and read https://medium.com/anton-on-security :-)
  • 14. Intermission: Is SOC Dead? ● SOC as a CROWDED ROOM may be dead… ● SOC as a detection and response team is NOT dead. ● Can it ever be dead? Well, now, this is a topic for another time …
