OWASP ZAP 2.17.0 — Checkmarx Security Platform

Executive 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.

⚠️ CRITICAL ALERT: Data exposure vulnerability discovered. Your teams must implement protective measures within 72 hours.

Key Management Priorities

PriorityTaskResponsible TeamDeadline
🔴 CriticalBlock vulnerable API endpointsBackend/DevOps teams24 hours
🟡 HighImplement security headersFrontend teams48 hours
🔵 MediumDeploy monitoring systemsSRE/Ops teams1 week
ℹ️ LowTeam security trainingAll teams2 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

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

Backend Team Lead Checklist:

Frontend Teams - HIGH PRIORITY

Issue: Missing basic security headers

Vulnerabilities: No CSP, X-Frame-Options, SRI

Risk: XSS attacks, clickjacking, supply chain attacks

Frontend Team Lead Checklist:

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):

    Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"

Nginx:

    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

DevOps Team Lead Checklist:

  1. Security Log Monitoring
  1. Configuration File Monitoring
  1. Automated Header Validation

Level 1: Detection (Development Teams)

Incident Indicators:

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):

mkdir -p $INCIDENT_DIR

# Recent changes

find /var/www -type f -mtime -1 > $INCIDENT_DIR/recent_changes.txt

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

Monthly Security Audits

Department Manager Procedure:

echo "Date: $(date)"

# Check users with sudo privileges

echo "Users with sudo privileges:"

grep -Po '^sudo.+:\K.*$' /etc/group

# Check failed login attempts

echo "Failed login attempts this month:"

grep "Failed password" /var/log/auth.log | wc -l

  1. Availability and Performance Monitoring

# Check availability

if curl -s --head $WEBSITE | head -n 1 | grep -q "200 OK"; then

echo "$(date): $WEBSITE - OK" >> $LOG_FILE

else

echo "$(date): $WEBSITE - DOWN" >> $LOG_FILE

# Send alert

echo "Website is down!" | mail -s "ALERT: Website Down" admin@company.com

fi

# Check security headers

HEADERS=$(curl -s -I $WEBSITE)

if echo "$HEADERS" | grep -q "X-Content-Type-Options"; then

echo "$(date): Security headers - OK" >> $LOG_FILE

else

echo "$(date): Security headers - MISSING" >> $LOG_FILE

fi

  1. Security Log Monitoring
for pattern in "${SUSPICIOUS_PATTERNS[@]}"; do
    if grep -i "$pattern" $SECURITY_LOG | tail -100 | grep -q "$(date +%Y-%m-%d)"; then
        echo "Suspicious activity detected: $pattern" | \
        mail -s "ALERT: Suspicious Activity" $ALERT_EMAIL
