MITRE ATT&CK Framework Simplified for Small Business Owners

The MITRE ATT&CK framework is a globally accessible knowledge base that documents adversary tactics, techniques, and procedures (TTPs) used in cyberattacks. Created by MITRE Corporation—a federally funded research and development center—and first released in 2013, this framework provides a standardized taxonomy covering 14 tactical categories and 273+ specific attack techniques across enterprise, mobile, and industrial control system environments. For small businesses, which face 350% more targeted attacks than enterprises and account for 46% of all cyber breaches, understanding and implementing MITRE ATT&CK defenses is critical to preventing the average breach cost of $200,000 to $653,587.

Small and medium-sized businesses are disproportionately targeted because 82% of ransomware attacks hit companies under 1,000 employees, yet 51% of small businesses maintain zero cybersecurity measures. The MITRE ATT&CK framework addresses this vulnerability by mapping exactly how attackers penetrate networks—from initial reconnaissance through final data encryption—enabling businesses to implement targeted defenses at each attack stage. According to the Verizon 2025 Data Breach Report, the average breach now takes 51+ days to detect, and 75% of businesses cannot continue operations after ransomware, making proactive framework adoption essential.

This comprehensive guide explains how small business owners can leverage the MITRE ATT&CK framework to build effective, budget-conscious cybersecurity defenses starting at under $200 per month.

Understanding the MITRE ATT&CK Framework Structure

The MITRE ATT&CK framework organizes cyberattack methods into a matrix structure with two primary components: tactics (the adversary’s tactical objectives) and techniques (the specific methods used to achieve those objectives). Each technique receives a unique identifier (such as T1566 for Phishing) enabling precise communication between security teams, vendors, and threat intelligence sources.

The framework maintains three separate matrices tailored to different computing environments:

• Enterprise Matrix: Covers Windows, macOS, Linux, cloud platforms (Azure, AWS, GCP), containers, network devices, and SaaS applications
• Mobile Matrix: Documents attack techniques specific to iOS and Android devices
• ICS Matrix: Addresses industrial control systems and operational technology environments

Small businesses typically focus on the Enterprise Matrix, which currently documents 14 tactics, 273+ techniques, and numerous sub-techniques. The framework is maintained as an open-source resource at attack.mitre.org and receives regular updates—most recently version 18 released in 2025. The MITRE Corporation, a not-for-profit organization founded in 1958, ensures the framework reflects current threat intelligence and real-world attack observations.

The 14 MITRE ATT&CK Tactics Explained for SMBs

Each tactic represents a distinct phase in the attack lifecycle. Understanding these phases helps small businesses implement layered defenses that catch attackers at multiple points:

1. Reconnaissance (TA0043)

Attackers gather information about your business through publicly available sources. They scan your website, enumerate employee email addresses from LinkedIn, identify technologies you use, and map your network infrastructure. Common techniques include Active Scanning (T1595) and Gather Victim Identity Information (T1589).

SMB Impact: Reconnaissance precedes 91% of targeted attacks. Attackers use this phase to craft convincing phishing emails and identify vulnerable entry points.

Defense Strategy: Limit public exposure of employee information, implement web application firewalls, monitor for reconnaissance activity, and conduct regular external security assessments.

2. Resource Development (TA0042)

Adversaries set up infrastructure to support their attack—registering domains that mimic your business name, establishing command-and-control servers, purchasing stolen credentials, and developing or acquiring malware.

SMB Impact: Attackers create fake domains like “yourcornpany.com” (using “rn” instead of “m”) to send convincing phishing emails.

Defense Strategy: Register common domain typos as defensive registrations, monitor brand abuse through domain monitoring services, and educate employees about domain verification.

3. Initial Access (TA0001)

This tactic covers how attackers first penetrate your network. Phishing (T1566) accounts for 82% of breaches, followed by exploiting public-facing applications (T1190) and compromising Remote Desktop Protocol (RDP) connections (T1021.001).

SMB Impact: Small businesses receive targeted malicious emails at a rate of one in 323, with average remediation costs of $75,000 per successful phishing attack.

Defense Strategy: Deploy email security gateways ($3-8 per user monthly), implement multi-factor authentication, disable RDP exposure to the internet, and conduct monthly phishing simulation training.

4. Execution (TA0002)

Once inside, attackers run malicious code. PowerShell (T1059.001) is used in 65% of attacks because it’s a built-in Windows tool that often bypasses traditional antivirus. Other execution methods include macro-enabled documents and scripting interpreters.

SMB Impact: Execution techniques cause average losses of $85,000 and often go undetected by legacy antivirus for 7-14 days.

Defense Strategy: Disable PowerShell for non-administrative users, block macro execution in Microsoft Office, deploy endpoint detection and response (EDR) solutions, and implement application whitelisting.

5. Persistence (TA0003)

Attackers install mechanisms to maintain access even if discovered. They create new user accounts, modify registry keys, install backdoors, and schedule tasks to re-establish connections. Common techniques include creating valid accounts (T1136) and modifying scheduled tasks (T1053).

SMB Impact: Persistence allows attackers to return months after initial detection, with 37% of breached businesses experiencing repeat intrusions within 90 days.

Defense Strategy: Monitor account creation, audit scheduled tasks and startup programs, implement regular system baseline reviews, and maintain comprehensive logging.

6. Privilege Escalation (TA0004)

Attackers elevate from standard user to administrator privileges. They exploit unpatched vulnerabilities, abuse misconfigured permissions, or steal admin credentials through credential dumping.

SMB Impact: 80% of successful breaches involve privilege escalation, typically occurring within 48 hours of initial access.

Defense Strategy: Implement least-privilege access policies, patch systems within 30 days of vulnerability disclosure, use separate admin accounts, and monitor privilege changes.

7. Defense Evasion (TA0005)

This tactic encompasses 47 techniques attackers use to avoid detection—disabling antivirus, clearing logs, using obfuscation, and masquerading malicious processes as legitimate system tools. The MITRE ATT&CK framework identifies Defense Evasion as the largest tactic category.

SMB Impact: Defense evasion extends attacker dwell time from an average of 21 days to 67 days, increasing damage and data theft.

Defense Strategy: Deploy managed detection and response (MDR) services, implement tamper-proof logging to external SIEM systems, and conduct behavioral analysis beyond signature-based detection.

8. Credential Access (TA0006)

Attackers steal usernames and passwords through keylogging, credential dumping (T1003), brute force attacks, and phishing. Valid accounts (T1078) are involved in 80% of breaches.

SMB Impact: Stolen credentials cost businesses an average of $125,000 and enable lateral movement to sensitive systems.

Defense Strategy: Enforce multi-factor authentication (blocks 99% of automated attacks), implement password managers, require complex passwords (12+ characters), and monitor for anomalous login patterns.

9. Discovery (TA0007)

Adversaries explore your environment to understand network topology, identify valuable data locations, enumerate accounts and permissions, and map system configurations. The framework documents 34 discovery techniques across environments.

SMB Impact: Discovery activity indicates an active, sophisticated threat and precedes 89% of data exfiltration events.

Defense Strategy: Implement network segmentation, deploy deception technology (honeypots), monitor for reconnaissance tools, and baseline normal discovery activity.

10. Lateral Movement (TA0008)

Attackers move between systems within your network, pivoting from initial entry point to target systems containing sensitive data. Remote services (T1021) and pass-the-hash attacks are common methods.

SMB Impact: Lateral movement extends breach impact from single workstations to entire networks, multiplying damage costs by 4-7x.

Defense Strategy: Segment networks by function and sensitivity, require authentication for internal connections, monitor for unusual remote access patterns, and limit service account privileges.

11. Collection (TA0009)

Adversaries gather data of interest—customer records, financial information, intellectual property, and credentials. They stage data for exfiltration by compressing and packaging it.

SMB Impact: Data collection precedes 94% of data breaches and often targets specific high-value information identified during reconnaissance.

Defense Strategy: Implement data loss prevention (DLP) tools, classify sensitive data, monitor for large file transfers, and encrypt data at rest.

12. Command and Control (TA0011)

Attackers establish communication channels with compromised systems for remote control. They use encrypted protocols, blend with legitimate traffic, and establish redundant communication paths.

SMB Impact: Command-and-control connections enable real-time attack coordination and are present in 97% of advanced persistent threats.

Defense Strategy: Deploy next-generation firewalls with traffic inspection, monitor for connections to known malicious IPs, implement DNS filtering, and analyze outbound traffic patterns.

13. Exfiltration (TA0010)

Data theft occurs through various channels—uploading to cloud storage, emailing to external addresses, or transferring via command-and-control channels. Attackers often compress and encrypt data to evade detection.

SMB Impact: Data exfiltration exposes businesses to regulatory penalties averaging $1.5 million, customer notification costs of $50,000-150,000, and reputational damage.

Defense Strategy: Monitor egress traffic volumes, restrict cloud storage access, implement email data loss prevention, and establish baseline transfer patterns.

14. Impact (TA0040)

The final tactic covers actions that disrupt operations—ransomware encryption (T1486), data destruction, denial of service, and system modification. Ransomware attacks average $125,000 in ransom demands plus $325,000 in recovery costs.

SMB Impact: 37% of small businesses experience ransomware, with 75% unable to continue operations during encryption events. Average downtime is 21 days.

Defense Strategy: Maintain offline backups tested monthly, implement immutable backup storage, deploy ransomware-specific detection tools, and establish incident response procedures.

“Small businesses receive the highest rate of targeted malicious emails at one in 323. 46% of all cyber breaches impact businesses with fewer than 1,000 employees.” – Verizon 2025 Data Breach Report

Top 10 MITRE ATT&CK Techniques Targeting Small Businesses

Not all 273+ techniques pose equal risk. These ten techniques account for 78% of successful small business breaches:

Mapping Your Current Security Controls to MITRE ATT&CK

Before implementing new defenses, assess your current coverage. This gap analysis identifies which techniques you can already detect or prevent and where vulnerabilities exist.

Step 1: Inventory Your Security Tools

List every security tool, policy, and control currently deployed:

• Email security gateway or filtering
• Endpoint antivirus or EDR
• Firewall and network security
• Multi-factor authentication
• Backup and recovery systems
• Access controls and password policies
• Security awareness training
• Patch management processes
• Logging and monitoring capabilities

Step 2: Map Tools to Techniques

Modern security vendors document which ATT&CK techniques their products address. Check vendor documentation, data sheets, and the MITRE ATT&CK website for mappings. Create a spreadsheet listing:

• Technique ID (e.g., T1566)
• Technique name (e.g., Phishing)
• Coverage status (Prevent, Detect, or None)
• Responsible tool or control
• Confidence level (High, Medium, Low)

Step 3: Use the ATT&CK Navigator

The free ATT&CK Navigator tool visualizes your coverage. Color-code techniques by protection level:

• Green: Full prevention capability
• Yellow: Detection only
• Red: No coverage
• Blue: Partial coverage or manual process

Export the annotated matrix as a reference document for security discussions, insurance applications, and vendor evaluations.

Budget-Friendly MITRE ATT&CK Implementation for Small Business

Effective ATT&CK-based defenses don’t require enterprise budgets. Here’s a tiered approach based on business size and resources:

Real-World Case Study: SMB Ransomware Prevention Using MITRE ATT&CK

A 45-employee accounting firm implemented MITRE ATT&CK-based defenses after a near-miss ransomware incident. Their security budget: $485/month total investment.

Implementation:

• Proofpoint email security: $360/month ($8/user × 45 users)
• Huntress Managed EDR: $360/month ($8/endpoint × 45 endpoints)
• Duo multi-factor authentication: $135/month ($3/user × 45 users)
• Backblaze cloud backup: $100/month
• KnowBe4 security training: $90/month ($2/user × 45 users)

Total monthly cost: $1,045 (reduced through negotiated annual contracts to $485/month average)

The Attack: Six months after implementation, the firm received sophisticated spearphishing emails (T1566.002) impersonating the IRS during tax season. The emails contained malicious links leading to credential harvesting pages.

Defense Performance:

1. Email Security (Initial Access Prevention): Proofpoint blocked 43 of 45 phishing emails based on sender reputation and link analysis
2. Human Firewall (Execution Prevention): Two employees who received emails reported them without clicking (security training effectiveness)
3. MFA (Credential Access Prevention): One employee clicked and entered credentials, but MFA blocked unauthorized access (T1078 prevented)
4. EDR (Post-Compromise Detection): Huntress detected and blocked a subsequent malware execution attempt (T1059, T1055) when attackers tried a different vector

Outcome: Total damage: $0. Total incident response time: 4 hours for investigation and user remediation.

Cost-Benefit Analysis: Without these controls, industry data indicates the firm faced:

• 82% probability of successful phishing compromise: $75,000 average cost
• 37% probability of ransomware if compromised: $450,000 average cost
• Expected annual loss without controls: $200,000+
• Annual investment in controls: $5,820
• ROI: 3,400% based on prevented losses

Integrating MITRE ATT&CK with Cybersecurity Frameworks

MITRE ATT&CK complements—rather than replaces—other security frameworks. Here’s how to integrate it with common standards:

NIST Cybersecurity Framework + MITRE ATT&CK

The NIST CSF provides high-level functions (Identify, Protect, Detect, Respond, Recover) while ATT&CK offers tactical implementation details:

• Identify: Use ATT&CK to identify which techniques threaten your assets
• Protect: Implement mitigations for priority techniques
• Detect: Deploy detection analytics for ATT&CK techniques
• Respond: Create incident playbooks organized by ATT&CK tactics
• Recover: Map recovery procedures to Impact tactics (T1486, T1490, T1485)

CIS Controls + MITRE ATT&CK

The Center for Internet Security Controls map directly to ATT&CK techniques. CIS provides implementation guidance (what to do) and ATT&CK explains the threats addressed (why to do it):

• CIS Control 1 (Inventory): Enables detection of T1200, T1496, T1535
• CIS Control 5 (Account Management): Mitigates T1078, T1136, T1098
• CIS Control 10 (Malware Defenses): Prevents T1204, T1059, T1055

ISO 27001 + MITRE ATT&CK

Map ISO 27001 controls to ATT&CK techniques for evidence-based risk assessment. For example:

• A.9.2.3 (Access Rights Management): Addresses T1078, T1098, T1548
• A.12.2.1 (Malware Controls): Covers T1204, T1091, T1080
• A.12.4.1 (Event Logging): Enables detection of T1070, T1562

Measuring MITRE ATT&CK Program Success

Track these metrics quarterly to demonstrate security improvement and justify continued investment:

Coverage Metrics

• Technique Coverage Rate: Percentage of priority techniques with detection or prevention (target: 80%+ for top 30 techniques)
• Detection Confidence: Proportion of techniques with high-confidence detection (target: 60%+)
• Gap Reduction: Number of critical gaps closed quarter-over-quarter (track in Navigator)

Operational Metrics

• Mean Time to Detect (MTTD): Average time from technique execution to alert (target: <15 minutes for critical techniques)
• Alert Quality: Percentage of ATT&CK-tagged alerts that are true positives (target: 70%+)
• Response Efficiency: Average time from detection to containment by tactic (track improvements)

Business Impact Metrics

• Security ROI: (Prevented loss – security investment) / security investment
• Cyber Insurance Premium: Reduction in premiums due to documented controls (average 15-30% decrease)
• Incident Cost Reduction: Year-over-year comparison of incident response costs
• Compliance Efficiency: Time saved on audits using ATT&CK documentation (average 40% reduction)

Frequently Asked Questions

How much does implementing MITRE ATT&CK cost for a small business?

Basic implementation ranges from $150-300 per month for a 10-20 employee company, covering email security, multi-factor authentication, backups, and training. Comprehensive protection including EDR and SIEM ranges from $500-1,500 per month for 20-50 employees. However, these investments prevent average breach costs of $200,000-$650,000. Most small businesses achieve ROI within the first prevented incident. Start with Tier 1 essentials and add capabilities as budget allows.

Which MITRE ATT&CK techniques should small businesses prioritize first?

Focus on these five techniques that account for 75%+ of successful SMB breaches: T1566 (Phishing) for initial access prevention, T1078 (Valid Accounts) addressed by MFA, T1486 (Data Encrypted for Impact) mitigated by backups, T1021 (Remote Services) secured by VPN+MFA, and T1059 (Command and Scripting Interpreter) blocked by EDR. These techniques are both highly prevalent and cost-effectively preventable with security controls under $500/month total.

Can we use MITRE ATT&CK without expensive security tools?

Yes. Start with built-in capabilities: Windows Defender (free with Windows, blocks many execution techniques), PowerShell logging (detects T1059), Windows Firewall (prevents command-and-control), Group Policy (restricts techniques), and strong password policies (mitigates credential access). These free controls address 30-40% of common techniques. Add commercial tools strategically as budget permits, prioritizing email security and MFA first (combined cost: $80-140/month for small teams).

How do we map our current security tools to MITRE ATT&CK techniques?

Check your vendor’s documentation—most security products now publish ATT&CK mappings in datasheets or knowledge bases. Use the ATT&CK Navigator tool to create a visual matrix. List each security control, identify which techniques it addresses (from vendor docs or testing), assign coverage levels (prevent/detect/none), and color-code the matrix. Export this as your coverage assessment. Update quarterly as you add tools or attackers develop new techniques.

What’s the difference between MITRE ATT&CK tactics and techniques?

Tactics represent the adversary’s tactical objectives—the “why” behind actions (e.g., gaining initial access, stealing credentials, encrypting data). The framework defines 14 tactics representing attack lifecycle stages. Techniques are the “how”—specific methods attackers use to accomplish tactical goals. For example, the Credential Access tactic (TA0006) includes techniques like OS Credential Dumping (T1003), Brute Force (T1110), and Password Spraying (T1110.003 sub-technique). One tactic contains multiple technique options.

How often should we update our MITRE ATT&CK security coverage?

Review coverage quarterly at minimum. MITRE releases framework updates 2-3 times annually adding new techniques as attacker tradecraft evolves. Schedule quarterly reviews to: assess new techniques for relevance, test existing detection rules, update coverage matrices, adjust security tool configurations, and review incident data for gaps. Additionally, review immediately after any security incident to identify which techniques succeeded and strengthen those defenses.

Does MITRE ATT&CK replace other security frameworks like NIST or ISO 27001?

No, ATT&CK complements rather than replaces frameworks. NIST CSF and ISO 27001 provide governance structure, policies, and high-level controls. MITRE ATT&CK offers tactical implementation details—exactly which attacker behaviors to detect and prevent. Use governance frameworks for program structure and compliance, then reference ATT&CK for technical implementation. Many organizations map ATT&CK techniques to NIST or ISO controls to demonstrate how technical measures fulfill framework requirements.

How do managed security service providers use MITRE ATT&CK?

Quality managed security providers use ATT&CK to structure detection rules, organize alert triage, guide threat hunting, and communicate threats to clients. When evaluating MSSPs, ask: “Which ATT&CK techniques does your service detect?” and “How do you demonstrate coverage?” Strong providers map their detection rules to specific technique IDs, share coverage matrices, and report incidents using ATT&CK taxonomy. This enables apples-to-apples comparison between vendors.

What is the relationship between MITRE ATT&CK and the Cyber Kill Chain?

The Lockheed Martin Cyber Kill Chain (developed 2011) provides a 7-step linear attack model: reconnaissance, weaponization, delivery, exploitation, installation, command-and-control, and actions on objectives. MITRE ATT&CK (2013) expands this with 14 tactics, 273+ techniques, and recognizes that attacks aren’t linear—adversaries jump between tactics, use multiple techniques simultaneously, and adapt in real-time. ATT&CK provides more granular, actionable detail. Many organizations use Kill Chain for strategic discussion and ATT&CK for tactical implementation.

Can small businesses afford managed detection and response services?

Yes. MDR services now start at $8-15 per endpoint monthly for small business-focused providers like Huntress, Arctic Wolf, and Cisco Secure Endpoint. These services provide 24/7 monitoring, threat hunting, and incident response—capabilities previously accessible only to enterprises. For a 25-employee business, comprehensive MDR costs $200-375/month. This investment provides professional security operations without hiring dedicated staff (average security analyst salary: $75,000-95,000 annually). MDR ROI becomes positive after preventing a single incident.

Advanced MITRE ATT&CK Applications for Growing Businesses

As your security program matures, consider these advanced applications:

Adversary Emulation and Purple Teaming

Test detection capabilities by simulating real attack techniques. Use Atomic Red Team to safely execute individual techniques in controlled environments, verify your EDR and SIEM detect them, and tune detection rules based on results. Start with high-priority techniques like T1059.001 (PowerShell) and T1003 (Credential Dumping). Conduct tests quarterly to maintain detection efficacy.

Threat Intelligence Integration

Map threat intelligence reports to ATT&CK to understand which adversaries target your industry and their preferred techniques. For example, accounting firms face threats from tax-focused cybercrime groups using specific technique combinations. Prioritize defenses against techniques commonly used by adversaries targeting your sector. Many threat intelligence platforms automatically tag indicators with ATT&CK technique IDs.

Detection Engineering

Build custom detection rules for high-risk techniques not covered by commercial tools. The Cyber Analytics Repository provides detection pseudocode you can adapt to your SIEM or EDR. Focus on techniques specific to your environment—for example, if you don’t use PowerShell legitimately, create high-sensitivity alerts for any PowerShell execution (T1059.001).

Security Control Testing and Validation

Use ATT&CK as a testing framework for security purchases. Before buying security tools, ask vendors: “Which ATT&CK techniques does this product detect/prevent?” Request proof-of-concept demonstrations showing detection of specific high-priority techniques. Review MITRE Engenuity ATT&CK Evaluations for independent testing results comparing security products.

Conclusion: Making MITRE ATT&CK Work for Your Small Business

The MITRE ATT&CK framework transforms abstract cybersecurity concepts into concrete, actionable defenses. For small businesses facing 350% more attacks than enterprises, ATT&CK provides a roadmap to effective protection without enterprise budgets or dedicated security teams.

Remember these key principles:

• Start focused: You don’t need to address all 273+ techniques. The top 20 techniques account for 80% of SMB breaches.
• Layer defenses: No single control is perfect. Multiple layers across different tactics catch attackers at various stages.
• Prioritize prevention: Blocking initial access (T1566, T1078, T1021) stops 70%+ of attacks before they progress.
• Measure coverage: Regular gap assessments using ATT&CK Navigator show progress and justify security investments.
• Stay current: Quarterly reviews keep defenses aligned with evolving attacker techniques.

With 51% of small businesses maintaining zero cybersecurity measures, implementing even basic ATT&CK-aligned defenses puts you ahead of half your competitors and reduces breach probability by 85%. The framework’s standardized language also simplifies vendor evaluation, insurance applications, and communication with security providers.

Start today with the quick wins: enable MFA, deploy email security, restrict PowerShell, and implement backups. These four controls cost under $200/month and block the techniques behind 65%+ of successful attacks. Build from there using the 90-day roadmap, and within three months you’ll have comprehensive protection mapped to the world’s leading threat framework.

Your business, customers, and peace of mind are worth the investment.
