sudo chown -R nexus:nexus /opt/nexus
sudo chmod -R 755 /opt/nexus

2. Application Security

Environment Variables Security

# Secure .env file
chmod 600 .env

# Remove sensitive files from git
echo ".env" >> .gitignore
echo "logs/" >> .gitignore

Security Headers

# Add security headers to Nginx
# Add to server block in Nginx config
add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";
