Importance of a Security Operations Center (SOC)
By Adrian Anglin Published: December 25, 2025
In an environment where attackers exfiltrate data within 24 hours, and ransomware executes in under 5 days, the SOC is the difference between a contained incident and a catastrophic breach.
Introduction
The current threat landscape leaves no room for passive security postures. Ransomware attacks continue to escalate, with average breach costs reaching $4.88 million globally and $9.77 million in healthcare. Attackers are faster than everβmedian time to data exfiltration has compressed to 2 days, with 45% of threat actors stealing data within 24 hours of initial access.
Two capabilities anchor effective cyber defence: the Security Operations Centre (SOC) for continuous detection and monitoring, and Digital Forensics & Incident Response (DFIR) for containment and investigation when breaches occur. Together, they form an integrated defence that detects threats early, responds rapidly, and learns from every incident.
This article examines why SOC and DFIR capabilities are strategically essentialβnot as cost centres, but as business-critical functions that determine whether organisations survive modern cyber threats.
The Threat Landscape: Why Detection is Non-Negotiable
The Current State
The asymmetry between attackers and defenders has never been starker:
Average breach cost
$4.88M (10% YoY increase)
Healthcare breach cost
$9.77M
Median attacker dwell time
5β10 days
Ransomware dwell time
5 days
Time to data exfiltration
2 days (45% within 24 hours)
Breaches involving cloud data
82%
Attacks using stolen credentials
16% (longest to detect at 292 days)

Evolving Adversary Tradecraft
Modern threat actors have professionalised their operations:
Ransomware-as-a-Service (RaaS): Groups like LockBit, BlackCat/ALPHV, and Qilin operate with business efficiency. 87% of ransomware attacks now involve double extortionβencryption plus data theft
Living-off-the-land (LOTL): Adversaries use legitimate tools (PowerShell, WMI, RDP) to evade detection and blend with normal operations
Supply chain compromise: The Snowflake breach affected 165+ customer organisations through a single platform compromise
AI-enhanced attacks: GenAI is lowering barriers to sophisticated phishing, deepfake social engineering, and automated reconnaissance
Identity-focused attacks: Credential theft and MFA bypass remain primary initial access vectors
The Detection Imperative
Prevention alone is insufficient. Attackers need one successful entry point; defenders must protect every surface. Detection inverts this asymmetryβcatching threats mid-execution, limiting dwell time, and shrinking the window for damage.
Without effective detection:
Threats dwell undetected for weeks or months
Minor footholds escalate into full domain compromise
Data exfiltration completes before response begins
Remediation is incomplete, leading to reinfection (67% of inadequately remediated breaches see repeat incidents)
The Role of SOC Monitoring and Detection
What the SOC Provides
The Security Operations Centre functions as the organisation's central nervous system for threat detection. It provides:
Continuous monitoring
24/7 visibility across endpoints, network, cloud, and identity
Alert triage
Distinguishing true threats from noise
Threat hunting
Proactive search for undetected adversary activity
Detection engineering
Building and tuning rules to catch evolving threats
Incident escalation
Triggering response workflows when threats are confirmed
Core Technology Stack
Effective SOCs integrate multiple detection layers:
SIEM/XDR: Centralised log aggregation, correlation, and alerting (Sentinel, Splunk, Defender XDR)
EDR: Endpoint visibility, behavioural detection, and response capabilities
NDR: Network traffic analysis and lateral movement detection
SOAR: Automated response playbooks and case management
Threat Intelligence: Real-time feeds on emerging TTPs and IOCs
The Human Element
Technology alone doesn't make a SOC effective. Skilled analysts provide:
Contextual understanding of the environment
Judgment calls on ambiguous alerts
Hypothesis-driven threat hunting
Detection logic tuning based on environmental baselines
Escalation decisions that balance speed with accuracy
SOC Models
In-house SOC
Fully internal team and infrastructure
Large enterprises with resources and talent
Managed SOC (MSSP)
Outsourced monitoring and alerting
Organisations lacking internal capability
MDR
Managed detection with active response
Mid-market needing detection + response
Hybrid
Internal team augmented by external services
Organisations scaling capability
{% hint style="info" %} Key insight: Organisations with dedicated SOC capabilities and tested incident response plans save an average of $248,000 per breach. Those using extensive AI and automation save $2.2 million. {% endhint %}
Incident Response: Speed Determines Outcome
Why Response Time Matters
When a threat is detected, the response window is measured in minutes, not hours. Ransomware can encrypt critical systems within hours of execution. Data exfiltration often completes before defenders know a breach occurred.
Effective incident response delivers:
Containment β Isolating affected systems before lateral movement completes
Eradication β Removing persistence mechanisms and attacker access
Recovery β Restoring operations from a validated clean state
Evidence preservation β Maintaining forensic integrity for investigation
The SOC-DFIR Handoff
SOC and DFIR operate as an integrated workflow:
Response Readiness
Organisations that prepare for incidents fare significantly better:
Tabletop exercises β Regular scenario-based practice builds muscle memory
Documented playbooks β Pre-defined procedures reduce decision time under pressure
Automated containment β SOAR-driven isolation removes human latency from critical actions
Communication plans β Stakeholder, legal, and regulatory notification procedures ready to execute
{% hint style="warning" %} Law enforcement engagement matters: Ransomware victims who involved law enforcement saved approximately $1 million in breach costs, and 63% avoided paying ransom entirely. {% endhint %}
Digital Forensics: Understanding What Happened
Beyond Containment
Stopping an attack is necessary but insufficient. Without understanding how the breach occurred, organisations remain vulnerable to repeat incidents.
Digital forensics provides:
Root cause identification β How did the attacker gain initial access?
Scope determination β What systems, accounts, and data were compromised?
Timeline reconstruction β What actions did the attacker take, and when?
Attribution β What TTPs indicate which threat actor or campaign?
Evidence preservation β Maintaining chain of custody for legal or regulatory needs
Operational Value
Forensic findings feed directly back into defensive operations:
Initial access vector identified
Patch vulnerability, improve email security, enforce MFA
Lateral movement path mapped
Segment network, restrict privileged access
Persistence mechanisms discovered
Update detection rules, hunt for similar artifacts
Data exfiltration confirmed
Scope notification requirements, engage legal
TTPs documented
Map to MITRE ATT&CK, build detection coverage
Compliance and Legal Requirements
Forensic capability is increasingly mandatory:
GDPR: 72-hour notification requires rapid scope determination
SEC Cyber Rules: 4-day disclosure for material incidents
DORA: 24-hour major incident reporting for financial entities
HIPAA/PCI-DSS: Investigation and documentation requirements
Without forensic capability, organisations cannot answer the questions regulators, insurers, and legal counsel will ask.
Building Capability: Bridging the Skills Gap
The Challenge
The cybersecurity skills shortage remains acute. Many organisations lack the resources to staff a full SOC or DFIR team. Analysts are often undertrained, overwhelmed by alert volume, and burning out.
Practical Solutions
For resource-constrained organisations:
MDR services
Variable (often affordable for SMEs)
Expert monitoring + response without headcount
CISA resources
Free
Foundational frameworks and guidance
Vendor training (Splunk, Microsoft, CrowdStrike)
Free to low-cost
Platform-specific skills
Community platforms (TryHackMe, LetsDefend)
$0β200/year
Hands-on analyst skill development
For organisations with existing teams:
Detection engineering focus β Train analysts to build and tune detections, not just triage alerts
Purple team exercises β Collaborative attack simulation validates and improves detection coverage
Cross-training β SOC analysts benefit from understanding DFIR; DFIR practitioners benefit from understanding detection engineering
Automation investment β SOAR reduces manual workload, freeing analysts for higher-value work
Building a Sustainable Program
The goal is not just filling seatsβit's building capability that scales:
Start with MDR or MSSP if internal resources are limited
Invest in training to grow internal expertise over time
Automate repetitive tasks to maximise analyst effectiveness
Document everythingβplaybooks, detections, lessons learned
Measure what matters: MTTD, MTTR, detection coverage, false positive rates
Strategic Recommendations
Immediate Actions
Deploy or optimise SIEM/XDR β Centralised visibility is foundational
Implement EDR across all endpoints β No visibility means no detection
Document incident response procedures β Plans tested before incidents occur
Establish law enforcement relationships β Before you need them
Run tabletop exercises β Quarterly at minimum
Medium-Term Investments
Build detection engineering capability β Move from reactive triage to proactive detection
Integrate SOAR β Automate containment and reduce response latency
Develop threat hunting program β Find adversaries that evade automated detection
Map detection coverage to ATT&CK β Identify and prioritise gaps
Establish forensic readiness β Tools, training, and evidence preservation procedures
Long-Term Considerations
The threat landscape will continue evolving:
AI-powered attacks will increase in sophistication and volume
Identity-based attacks will intensify as perimeters dissolve
Supply chain risk will require deeper vendor security integration
Regulatory requirements will expand, and enforcement will increase
Organisations that invest in SOC and DFIR capability today are building the foundation to adapt to tomorrow's threats.
Conclusion
SOC and DFIR are not optional capabilitiesβthey are strategic necessities that determine organisational resilience. The data is clear:
Organisations with effective detection and response capabilities experience lower breach costs
Rapid containment prevents minor incidents from becoming catastrophic breaches
Forensic understanding prevents repeat incidents and satisfies regulatory requirements
Investment in people, process, and technology delivers a measurable return
The question is not whether your organisation will face a cyber incident, but whether you will detect it in time, respond effectively, and learn from it.
Detection is not a cost centre. It is the capability that determines whether your organisation weathers the inevitable attackβor becomes another case study in what happens when threats go unnoticed.
Build the SOC. Train the team. Test the plan. The adversaries aren't waiting.
