Abstract
Small and medium-sized enterprises increasingly depend on web applications and ecommerce platforms as essential components of their operating infrastructure. Content-management systems such as Joomla and WordPress, ecommerce platforms such as Magento, and enterprise applications built using Java and Spring Boot have become business-critical systems rather than simply websites.
This transformation has also expanded the attack surface.
A contemporary business application may depend simultaneously on Linux, Nginx, Apache, PHP, PHP-FPM, Java, Spring Boot, MariaDB, MySQL, Redis, OpenSearch, Docker, Composer, JavaScript packages, third-party extensions, APIs, payment gateways, DNS, TLS, cloud infrastructure and external services.
Consequently, application security cannot be addressed effectively through an isolated vulnerability scanner.
This paper proposes a KeenComputer Continuous Web Application Security Engineering Platform that integrates:
- Kali Linux
- Metasploit Framework
- OWASP Web Security Testing Guide
- OWASP Top 10
- OWASP ZAP
- Nmap
- Nuclei
- Nikto
- WPScan
- Amass
- SQLMap
- FFUF
- Gobuster
- WhatWeb
- Semgrep
- Trivy
- ClamAV
- Lynis
- RKHunter
- AIDE
- tcpdump/Wireshark
- Docker
- CI/CD security controls
- vulnerability-management processes
- security reporting
- AI-assisted analysis
The proposed architecture deliberately separates development testing, staging assessment and authorized production assessment.
The central thesis is that security scanning should become part of the software-engineering lifecycle rather than a periodic activity performed after deployment.
The proposed model positions KeenComputer as the engineering and implementation organization, IAS-Research as the research, architecture and strategic advisory layer, and KeenDirect as the potential productization and managed-service channel.
1. Introduction
Digital transformation has fundamentally changed the security requirements of SMEs.
A business may begin with a simple website and eventually develop an infrastructure containing:
Domain │ ├── DNS ├── Email ├── Website ├── Ecommerce ├── CRM ├── APIs ├── Cloud VPS ├── Databases ├── Customer accounts ├── Payment systems └── Internal applications
The website consequently becomes part of the organization's operational technology.
A compromise can affect:
- revenue
- customer trust
- search-engine reputation
- confidential information
- intellectual property
- payment operations
- email systems
- business continuity
- regulatory obligations
- supplier relationships
Security must therefore be treated as an engineering discipline.
2. Research Objective
The objective of this research is to define a practical architecture through which an SME can continuously assess and improve the security of its web applications and supporting infrastructure.
The proposed platform addresses five questions:
- How can security testing be integrated into application development?
- How can Joomla, WordPress and Magento be assessed systematically?
- How can VPS and container infrastructure be incorporated into application security?
- How can offensive security tools such as Metasploit be used responsibly for validation?
- How can a technology provider such as KeenComputer transform security tooling into a repeatable engineering service?
3. Security as an Engineering Problem
A common misconception is:
Security equals vulnerability scanning.
This model is incomplete.
A vulnerability scanner answers:
"What might be wrong?"
Security engineering must answer:
"What does it mean, how serious is it, how can it be fixed, and how do we know the fix worked?"
The complete lifecycle is:
Discover ↓ Identify ↓ Assess ↓ Prioritize ↓ Validate ↓ Remediate ↓ Retest ↓ Monitor ↓ Improve
This distinction is central to the KeenComputer strategy.
4. Industry Frameworks
The proposed platform should align with established security frameworks rather than creating an isolated proprietary methodology.
4.1 OWASP Top 10
The current OWASP Top 10:2025 identifies ten major web-application risk categories:
- Broken Access Control
- Security Misconfiguration
- Software Supply Chain Failures
- Cryptographic Failures
- Injection
- Insecure Design
- Authentication Failures
- Software or Data Integrity Failures
- Security Logging and Alerting Failures
- Mishandling of Exceptional Conditions
This provides a high-level risk taxonomy for the proposed platform.
5. OWASP Web Security Testing Guide
The OWASP Web Security Testing Guide provides a structured methodology for testing web applications and web services and is intended for security professionals, developers and penetration testers. (OWASP Web Security Testing Guide)
The KeenComputer methodology should therefore map technical testing to OWASP categories:
Information Gathering ↓ Configuration Testing ↓ Identity Management ↓ Authentication ↓ Authorization ↓ Session Management ↓ Input Validation ↓ Business Logic ↓ Client-Side Testing ↓ API Testing
This is more defensible than simply running a collection of unrelated scanners.
6. NIST Secure Software Development
The proposed architecture also aligns with NIST SP 800-218, the Secure Software Development Framework.
NIST describes SSDF as a set of high-level secure-development practices that can be integrated into an organization's software-development lifecycle. Its objectives include reducing vulnerabilities, reducing the impact of vulnerabilities that escape detection, and addressing root causes so vulnerabilities do not repeatedly recur. (NIST Computer Security Resource Center)
This leads to an important design principle:
Security testing should begin before production.
7. Proposed KeenComputer Security Architecture
The architecture consists of four major environments.
┌───────────────────────┐ │ DEVELOPMENT │ │ │ │ Joomla │ │ WordPress │ │ Magento │ │ Spring Boot │ └───────────┬───────────┘ │ ▼ ┌───────────────────────┐ │ STAGING │ │ │ │ ZAP │ │ Nuclei │ │ Nmap │ │ Semgrep │ │ Trivy │ └───────────┬───────────┘ │ ▼ ┌───────────────────────┐ │ PRODUCTION │ │ │ │ Authorized Assessment │ │ Monitoring │ │ Integrity │ │ Logging │ └───────────────────────┘
A fourth environment is the security research laboratory:
Kali Metasploit OWASP Juice Shop DVWA WebGoat Vulnerable CMS Vulnerable APIs Test databases
8. Kali Linux as the Security Engineering Workbench
Kali Linux provides a mature environment for security assessment.
Kali maintains official Docker images, including kalilinux/kali-rolling, and documents containerized use of Kali's security tooling. The official images do not contain the default Kali metapackage automatically, so appropriate packages must be installed for the intended workload. (Kali Linux)
The KeenComputer environment can use Kali as a security-engineering workbench rather than treating it as a production server.
The workbench can include:
Reconnaissance Nmap Amass WhatWeb Web Security ZAP Nikto Nuclei SQLMap CMS Security WPScan Application Testing FFUF Gobuster Source Security Semgrep Container Security Trivy Host Security Lynis RKHunter ClamAV AIDE Validation Metasploit
9. Metasploit
Metasploit has an important but carefully controlled role.
It should not be used indiscriminately against production systems.
The recommended model is:
Scanner finding ↓ Risk assessment ↓ Authorization ↓ Controlled validation ↓ Evidence ↓ Remediation ↓ Regression test
Metasploit therefore becomes a validation engine, not simply an exploitation engine.
For production environments, testing rules should explicitly define:
- authorized targets
- testing window
- permitted techniques
- prohibited techniques
- rate limits
- rollback procedures
- emergency contacts
- data-handling requirements
10. Web Application Security Toolchain
10.1 Nmap
Used for:
- service discovery
- port discovery
- version identification
- TLS analysis
- network mapping
10.2 Nuclei
Used for:
- template-based vulnerability detection
- technology detection
- misconfiguration detection
- security regression testing
10.3 OWASP ZAP
Used for:
- web proxying
- spidering
- passive analysis
- active testing
- API assessment
- regression testing
10.4 Nikto
Used for:
- web-server configuration assessment
- known dangerous files
- legacy configurations
- server fingerprinting
10.5 WPScan
Used for specialized WordPress assessment.
10.6 Amass
Used for attack-surface discovery and external asset mapping.
10.7 SQLMap
Used in controlled environments to validate suspected SQL-injection conditions.
10.8 FFUF and Gobuster
Used for controlled discovery of:
- directories
- endpoints
- files
- virtual hosts
11. Joomla Security Model
Joomla assessment should include five dimensions.
Application
- core version
- extensions
- templates
- plugins
- administrator accounts
- ACL
- configuration
PHP
- PHP version
- dangerous functions
- configuration
- upload handling
- PHP-FPM
Web Server
- Nginx/Apache
- headers
- TLS
- directory exposure
- HTTP methods
Database
- MariaDB/MySQL
- credentials
- permissions
- exposed ports
Integrity
- unexpected PHP files
- modified templates
- suspicious extensions
- SEO spam
- redirects
- administrator accounts
12. WordPress Security Model
WordPress presents a different security profile because its extension ecosystem is extensive.
The security model should include:
WordPress Core + Plugins + Themes + PHP + Database + wp-config.php + Uploads + REST API + Authentication + XML-RPC
Security testing should therefore combine automated scanning with configuration review.
A recurring assessment can monitor:
- vulnerable plugins
- vulnerable themes
- outdated core
- exposed administrative services
- suspicious files
- authentication weaknesses
- unnecessary services
- security headers
13. Magento Ecommerce Security
Magento requires a deeper engineering approach.
Its security boundary includes:
Customer Browser ↓ CDN / Firewall ↓ Nginx ↓ Varnish ↓ Magento ↓ PHP-FPM ↓ MariaDB ↓ Redis ↓ OpenSearch ↓ External APIs
The platform should therefore evaluate:
Application
- Magento core
- modules
- themes
- admin
- REST
- GraphQL
Software Supply Chain
- Composer
- PHP packages
- JavaScript packages
- extensions
Infrastructure
- Docker
- Nginx
- PHP-FPM
- Redis
- OpenSearch
- database
Business Logic
- customer registration
- authentication
- checkout
- coupons
- pricing
- inventory
- order processing
- payment workflows
This is particularly important because not every serious ecommerce vulnerability will be identified by a generic scanner.
14. Java and Spring Boot
The same architecture should support enterprise Java applications.
The security model includes:
Spring Boot ↓ REST APIs ↓ Authentication ↓ Authorization ↓ Business Logic ↓ Database ↓ Dependencies ↓ Container ↓ Linux
Testing should address:
- insecure endpoints
- authentication failures
- authorization failures
- insecure actuator exposure
- dependency vulnerabilities
- injection
- SSRF
- deserialization
- secrets
- TLS
- container configuration
15. Docker Security
Docker introduces both security benefits and risks.
The assessment should examine:
- privileged containers
- excessive Linux capabilities
- host filesystem mounts
- Docker socket exposure
- secrets
- image vulnerabilities
- outdated base images
- network segmentation
- container users
- exposed ports
A particularly important principle is:
The security scanner should not automatically become a privileged component of the production environment.
Kali's own documentation notes limitations of containerized Kali, including hardware access and complications with inbound connections. (Kali Linux)
Therefore, a dedicated VM or isolated security workstation may remain preferable for certain assessment tasks.
16. VPS Security Architecture
A production VPS should implement layered controls.
INTERNET │ ▼ CLOUD FIREWALL │ ▼ UFW │ ▼ NGINX │ ┌─────┴─────┐ ▼ ▼ VARNISH APIs │ ▼ APPLICATION │ ┌─────────┼─────────┐ ▼ ▼ ▼ MariaDB Redis OpenSearch
The cloud firewall provides the external control plane.
UFW provides host-level policy.
Nginx provides application-facing controls.
The application provides authentication and authorization.
17. Host Security
KeenComputer-managed VPS environments should consider:
- UFW
- Fail2ban
- AppArmor
- auditd
- ClamAV
- RKHunter
- AIDE
- Lynis
- secure SSH
- patch management
- centralized logging
- backup verification
The objective is defense in depth.
18. Security Testing Pipeline
A standardized pipeline can be defined as:
Phase 1 Asset Discovery ↓ Phase 2 Technology Identification ↓ Phase 3 Vulnerability Detection ↓ Phase 4 Application Testing ↓ Phase 5 Source and Dependency Analysis ↓ Phase 6 Infrastructure Assessment ↓ Phase 7 Controlled Validation ↓ Phase 8 Risk Classification ↓ Phase 9 Remediation ↓ Phase 10 Retesting
19. Security Evidence and Reporting
Each assessment should create an evidence package.
Assessment/ │ ├── executive-summary/ ├── scope/ ├── asset-inventory/ ├── reconnaissance/ ├── network/ ├── web/ ├── cms/ ├── api/ ├── source-code/ ├── dependencies/ ├── containers/ ├── host/ ├── evidence/ ├── remediation/ └── retest/
This makes the process repeatable and auditable.
20. Risk-Based Reporting
Security reports should not simply provide hundreds of scanner findings.
They should answer:
What happened?
Why does it matter?
What systems are affected?
What is the business impact?
How difficult is exploitation?
What should be fixed first?
How should it be fixed?
How will remediation be verified?
An executive dashboard could therefore report:
Critical 1 High 4 Medium 12 Low 18 Security posture: Improving Highest risk: Ecommerce application Primary recommendation: Patch vulnerable extension and harden administrative access.
21. Continuous Security
The long-term goal is continuous security.
Git ↓ Build ↓ Semgrep ↓ Dependency Scan ↓ Trivy ↓ Container Build ↓ Staging ↓ ZAP ↓ Nuclei ↓ Security Approval ↓ Production ↓ Monitoring ↓ Periodic Assessment
Security becomes a continuous feedback loop rather than a one-time audit.
22. AI-Assisted Security Engineering
AI can enhance the platform without replacing human security professionals.
Potential applications include:
Finding correlation
Multiple scanners may report the same underlying problem.
AI can correlate:
Nmap + Nuclei + ZAP + Nikto
into a single finding.
Risk explanation
AI can translate technical vulnerabilities into business consequences.
Remediation assistance
AI can generate:
- configuration recommendations
- patch plans
- test procedures
- developer explanations
Security knowledge base
A RAG-based security assistant can index:
- previous assessments
- remediation records
- architecture documents
- CVE information
- OWASP material
- internal standards
- configuration baselines
Human review remains mandatory for consequential decisions.
23. KeenComputer Strategic Position
The proposed architecture creates an opportunity for KeenComputer to move beyond conventional IT support.
The strategic positioning becomes:
KeenComputer helps SMEs engineer secure digital infrastructure—from application development through cloud deployment and ongoing operations.
This integrates:
IT Infrastructure + Cloud + Cybersecurity + Software Engineering + Ecommerce + DevSecOps + AI
This combination is particularly relevant to organizations that cannot economically maintain large internal cybersecurity engineering teams.
24. IAS-Research Strategic Role
IAS-Research should function as the research and architecture organization.
Responsibilities can include:
- security research
- threat modeling
- architecture
- technical white papers
- technology evaluation
- AI-assisted security research
- DevSecOps methodology
- security standards
- vulnerability research
- engineering roadmaps
IAS-Research therefore creates the intellectual and methodological foundation.
25. KeenComputer Strategic Role
KeenComputer becomes the implementation and engineering organization.
Its responsibilities can include:
- infrastructure assessment
- VPS hardening
- web application security
- Docker security
- Joomla security
- WordPress security
- Magento security
- Java/Spring security
- monitoring
- remediation
- migration
- backup
- incident response
- managed security
The key commercial distinction is:
KeenComputer does not merely identify problems; it can engineer the remediation.
26. KeenDirect Strategic Role
KeenDirect can eventually productize the capability.
Potential offerings include:
Web Security Monitor
For Joomla and WordPress.
Ecommerce Security Monitor
For Magento, WooCommerce and OpenCart.
VPS Security Monitor
For Linux VPS environments.
Developer Security Lab
A packaged Docker security environment.
SME Security Assessment
A standardized assessment and remediation package.
27. SME Security-as-a-Service Model
A recurring offering could be structured around:
MONTHLY External attack-surface scan + Web vulnerability scan + CMS assessment + TLS assessment + Security configuration review + Malware indicators + Patch review + Executive report
Quarterly:
Deeper application assessment + Infrastructure review + Configuration audit + Remediation verification
Annually:
Comprehensive security assessment + Architecture review + Business continuity review + Security roadmap
28. Security Maturity Roadmap
Level 1 — Basic
Firewall Backups Updates Antivirus
Level 2 — Managed
Monitoring Vulnerability scanning Centralized reporting
Level 3 — Engineered
DevSecOps Source scanning Container scanning Security testing
Level 4 — Continuous
Continuous assessment Threat intelligence Automated remediation workflows
Level 5 — Intelligent
AI-assisted security operations RAG security knowledge base Automated correlation Predictive risk analysis
29. Governance and Authorization
Security testing must be performed only against systems for which the organization has explicit authorization.
Before an assessment:
Authorization ↓ Scope ↓ Rules of Engagement ↓ Testing Window ↓ Backup Verification ↓ Assessment ↓ Evidence ↓ Remediation ↓ Retest
This is particularly important for active tools such as Metasploit and SQLMap.
Production environments should use the least intrusive testing necessary to establish the risk.
30. Research Proposition
The principal research proposition of this paper is:
An integrated security-engineering platform combining application assessment, infrastructure assessment, software supply-chain analysis, controlled validation, DevSecOps automation and continuous monitoring can provide SMEs with a more sustainable security capability than periodic vulnerability scanning alone.
The proposition can be tested through measurable outcomes:
- reduction in critical vulnerabilities
- reduction in time-to-remediation
- reduction in recurring vulnerabilities
- reduction in configuration weaknesses
- improved patch compliance
- improved backup confidence
- improved security visibility
- improved incident-response readiness
31. Implementation Roadmap

- dependency scanning
- security regression testing
Phase 4 — Production
Introduce:
- external attack-surface monitoring

Phase 5 — Managed Security
Create:
- monthly assessments
- quarterly reviews
- remediation services
- executive dashboards
- security roadmaps
- managed monitoring
32. Strategic Business Opportunity
The SME market presents a significant opportunity because many organizations require enterprise-quality security practices without maintaining enterprise-sized security departments.
KeenComputer can bridge this gap by combining:
Engineering Expertise + Cybersecurity + Cloud Infrastructure + Ecommerce + DevSecOps + AI
The competitive advantage is not ownership of Kali Linux or Metasploit.
Those are widely available technologies.
The differentiator is the ability to integrate them into a repeatable engineering and business process.
33. Conclusion
Web application security has evolved from a specialized penetration-testing activity into a continuous engineering requirement.
Joomla, WordPress, Magento and Java/Spring Boot applications cannot be secured effectively by treating the application as an isolated software package.
Security extends across:
Code Dependencies Containers Operating System Network Web Server Database APIs Authentication Business Logic Cloud Monitoring Backups People Processes
The proposed KeenComputer security architecture integrates these dimensions into one lifecycle:
RESEARCH ↓ ARCHITECTURE ↓ DEVELOPMENT ↓ SECURITY TESTING ↓ DEPLOYMENT ↓ MONITORING ↓ REMEDIATION ↓ RETESTING ↓ CONTINUOUS IMPROVEMENT
Kali Linux provides the security engineering workbench.
OWASP provides application-security methodology and risk guidance.
NIST SSDF provides a secure-development framework.
Metasploit provides controlled validation capabilities.
Docker provides reproducible laboratory environments.
Automated scanners provide repeatable evidence.
KeenComputer provides engineering implementation.
IAS-Research provides research, architecture and strategic insight.
KeenDirect provides a pathway toward productized and managed security services.
The resulting capability is therefore not simply a collection of cybersecurity tools.
It is a continuous security engineering platform for SME digital infrastructure.
