Test Network Infrastructure Configuration
High-Level Description
This test evaluates the security configuration of network infrastructure components that support the web application. It includes assessing web servers, application servers, database servers, load balancers, and administrative interfaces for misconfigurations, default credentials, and known vulnerabilities. Proper network infrastructure hardening is essential as vulnerabilities in these components can provide attackers with direct access to sensitive systems.

How to Test
Step 1: Infrastructure Discovery
# Port scanning for common services
nmap -sV -sC -p- target.com
# Quick scan of common ports
nmap -sV -p 21,22,23,25,80,110,143,443,445,3306,3389,5432,8080,8443 target.com
# UDP scan for additional services
nmap -sU -p 53,67,68,69,123,161,500 target.com
Step 2: Vulnerability Scanning
# Nessus scan (commercial)
# Configure and run via web interface
# OpenVAS scan (open source)
omp -u admin -w password --xml="<create_target><name>target</name><hosts>target.com</hosts></create_target>"
# Nikto web server scan
nikto -h https://target.com
# Nmap vulnerability scripts
nmap --script vuln target.com
Step 3: Administrative Interface Discovery
# Common admin paths
for path in admin administrator manager console cpanel plesk webmin phpmyadmin adminer; do
status=$(curl -s -o /dev/null -w "%{http_code}" "https://target.com/$path")
echo "$path: $status"
done
# Common admin ports
nmap -sV -p 8080,8443,9090,10000,2082,2083,2086,2087 target.com
Step 4: Default Credential Testing

# Test Tomcat default credentials
curl -u admin:admin https://target.com:8080/manager/html
# Test Jenkins
curl -u admin:admin https://target.com:8080/jenkins/
# Hydra brute force (with permission)
hydra -L users.txt -P passwords.txt target.com http-get /admin
Step 5: SSL/TLS Configuration Testing
# SSL Labs style test
sslyze --regular target.com
# testssl.sh
testssl.sh target.com
# Nmap SSL scripts
nmap --script ssl-enum-ciphers -p 443 target.com
Step 6: Service Configuration Review
# Check for information disclosure
curl -sI https://target.com | grep -i server
# Check security headers
curl -sI https://target.com | grep -iE 'x-frame|x-content|x-xss|strict-transport|content-security'
# Check for debugging enabled
curl -s https://target.com | grep -iE 'debug|trace|stack'

Remediation Guide
1. Patch Management
- Maintain current patch levels on all systems
- Subscribe to vendor security advisories
- Implement automated patch management
- Test patches before production deployment
2. Hardening Guidelines
# Disable unnecessary services
systemctl disable telnet
systemctl disable ftp
# Configure firewall (iptables example)
iptables -A INPUT -p tcp --dport 22 -s trusted_ip -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j DROP
# Restrict administrative access
# Allow admin interfaces only from internal network
3. Default Credential Removal
- Change all default credentials immediately after installation
- Implement strong password policies
- Use key-based authentication where possible
- Document all credential changes
4. Network Segmentation
[Internet]
|
[DMZ - Web Servers]
|
[Internal - App Servers]
|
[Restricted - Database Servers]
|
[Management - Admin Access]
5. Access Control
- Restrict administrative interfaces to internal networks
- Implement IP whitelisting
- Use VPN for remote administration
- Enable MFA for all admin access
