Cybersecurity Operational Plan: Manager and Team Lead Implementation Guide
Chief Information Security Officer
OWASP ZAP 2.17.0 — Checkmarx Security PlatformExecutive Summary for Managers
This document provides a practical implementation guide for cybersecurity measures at the team and department level. Based on the security audit conducted on December 30, 2025, critical vulnerabilities have been identified that require immediate operational action from middle management and team leads.
Key Management Priorities
| Priority | Task | Responsible Team | Deadline |
|---|---|---|---|
| 🔴 Critical | Block vulnerable API endpoints | Backend/DevOps teams | 24 hours |
| 🟡 High | Implement security headers | Frontend teams | 48 hours |
| 🔵 Medium | Deploy monitoring systems | SRE/Ops teams | 1 week |
| ℹ️ Low | Team security training | All teams | 2 weeks |
Team Responsibility Matrix
Immediate Actions (0-72 hours):
Backend teams: Close REST API vulnerabilities
DevOps teams: Configure secure server settings
QA teams: Validate security fixes
Short-term Tasks (1-4 weeks):
Frontend teams: Implement CSP and SRI
Infrastructure teams: Set up security monitoring
Security teams: Establish incident response procedures
Technical Situation and Team Priorities
- Critical Vulnerabilities by Team
- Backend/API Teams - CRITICAL PRIORITY
Issue: Personal data exposure through REST API
Vulnerability: /wp-json/wp/v2/users accessible without authentication
Risk: All user data publicly accessible
CVSS Score: 9.1 (Critical)
Immediate Actions:
// URGENT: Add to functions.php
- add_filter('rest_endpoints', function($endpoints) {
- if (isset($endpoints['/wp/v2/users'])) {
- unset($endpoints['/wp/v2/users']);
- }
- return $endpoints;
- });
Backend Team Lead Checklist:
- Immediately block access to /wp-json/wp/v2/users
- Audit all REST API endpoints
- Implement authentication for sensitive endpoints
- Set up API request logging
- Test changes on staging environment
Frontend Teams - HIGH PRIORITY
Issue: Missing basic security headers
Vulnerabilities: No CSP, X-Frame-Options, SRI
Risk: XSS attacks, clickjacking, supply chain attacks
Practical Solutions:
- Content Security Policy (CSP)
- <!-- Add to <head> -->
- <meta http-equiv="Content-Security-Policy"
- content="default-src 'self';
- script-src 'self' 'unsafe-inline' https://cdnjs.cloudflare.com;
- style-src 'self' 'unsafe-inline' https://fonts.googleapis.com;">
- Subresource Integrity (SRI)
- <!-- For all external resources -->
- <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"
integrity="sha384-vtXRMe3mGCbOeY7l30aIg8H9p3GdeSe4IFlP6G8JMa7o7lXvnz3GFKzPxzJdPfGK"
crossorigin="anonymous"></script>
Frontend Team Lead Checklist:
- Implement CSP headers
- Add SRI for all external resources
- Configure X-Frame-Options: DENY
- Test browser compatibility
- Update CI/CD pipeline for header validation
DevOps/Infrastructure Teams - HIGH PRIORITY
Issue: Insecure web server configuration
Vulnerabilities: Missing HSTS, software version disclosure
Risk: Man-in-the-middle attacks, information reconnaissance
Server Configurations:
Apache (.htaccess):
- <IfModule mod_headers.c>
- # Basic security headers
- Header always set X-Content-Type-Options "nosniff"
- Header always set X-Frame-Options "DENY"
- Header always set X-XSS-Protection "1; mode=block"
Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"
- # Hide server information
- Header always unset Server
- Header always unset X-Powered-By
- </IfModule>
- # Disable server signature
- ServerTokens Prod
- ServerSignature Off
Nginx:
- server {
- # Security headers
- add_header X-Content-Type-Options "nosniff" always;
- add_header X-Frame-Options "DENY" always;
- add_header X-XSS-Protection "1; mode=block" always;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
- # Hide version
- server_tokens off;
- more_clear_headers Server;
- }

- Processes and Procedures
- Incident Response Procedures
Level 1: Detection (Development Teams)
Incident Indicators:
- Unusual activity in logs
- Monitoring system alerts
- User reports of suspicious behavior
- Automated security check failures
Immediate Actions (first 15 minutes):
Stay calm - document all actions
Isolate - disable suspicious services
Notify - inform team lead and security team
Preserve - take snapshots of logs and system state
Notification Template:
SECURITY INCIDENT
Time: [YYYY-MM-DD HH:MM]
Discovered by: [Name]
System: [System/service name]
Description: [Brief problem description]
Actions taken: [What has been done]
Status: [Active/Contained/Resolved]
Level 2: Analysis (Team Leads)
Analysis Procedure (30-60 minutes):
- Information Gathering
- # Incident data collection script
- #!/bin/bash
- INCIDENT_ID=$(date +%Y%m%d_%H%M%S)
- INCIDENT_DIR="/var/log/incidents/$INCIDENT_ID"
mkdir -p $INCIDENT_DIR
- # Collect logs
- cp /var/log/apache2/access.log $INCIDENT_DIR/
- cp /var/log/apache2/error.log $INCIDENT_DIR/
- cp /var/log/security.log $INCIDENT_DIR/
- # System state
- ps aux > $INCIDENT_DIR/processes.txt
- netstat -tulpn > $INCIDENT_DIR/network.txt
- df -h > $INCIDENT_DIR/disk_usage.txt
# Recent changes
find /var/www -type f -mtime -1 > $INCIDENT_DIR/recent_changes.txt
- echo "Incident data collected in $INCIDENT_DIR"
- Incident Classification
Level 1: Informational (logging, monitoring)
Level 2: Warning (potential threat)
Level 3: Critical (active attack, data breach)
Escalation Decisions
Level 1 → Team Lead → Documentation
Level 2 → Team Lead + Security → Enhanced monitoring
Level 3 → Immediate escalation → Management + external experts
