🔒 SECURITY

File Permissions

# .env is readable only by root
chmod 600 /opt/blocked_calls/.env

# Scripts are executable
chmod +x /opt/blocked_calls/import_*.py
chmod +x /opt/blocked_calls/import_*.sh

# Directories are protected
chmod 755 /opt/blocked_calls/
chmod 750 /opt/blocked_calls/imports/
chmod 750 /var/log/blocked_calls/

Database Security

# User has only necessary privileges
mysql> GRANT SELECT, INSERT, UPDATE ON blocked_calls.* TO 'blocked_calls_user'@'localhost';

# Password should be strong and unique
# Store in .env only, never in scripts
# Rotate every 90 days

Best Practices

✅ Keep .env file secret
✅ Use strong database passwords
✅ Limit file system access
✅ Monitor import logs
✅ Regular backups
✅ Audit database changes

📞 SUPPORT & TROUBLESHOOTING

Common Issues

Import fails: "Connection refused"

• Check MariaDB is running: sudo systemctl status mariadb
• Verify credentials in .env
• Test connection: mysql -u root -p

Script permission denied

• Make executable: sudo chmod +x /opt/blocked_calls/import_*.py
• Check ownership: ls -la /opt/blocked_calls/import_*

No files to import

• Check directory: ls -la /opt/blocked_calls/imports/
• Verify JSON format: python3 -m json.tool file.json
• Check file permissions: ls -la *.json

Database errors

• Check schema: mysql -u blocked_calls_user -p blocked_calls -e "SHOW TABLES;"
• Verify user permissions: SHOW GRANTS FOR blocked_calls_user;
• Check disk space: df -h /var/lib/mysql

Diagnostic Commands

# System info
uname -a
cat /etc/os-release
python3 --version
mysql --version

# Database check
mysql -u blocked_calls_user -p blocked_calls -e "SELECT VERSION();"
mysql -u blocked_calls_user -p blocked_calls -e "SELECT COUNT(*) FROM blocked_calls;"

# Log check
tail -50 /var/log/blocked_calls/import_*.log
tail -20 /var/log/blocked_calls/cron.log

# Cron check
crontab -l
sudo journalctl -u cron -n 20

🔄 BACKUP & RECOVERY

Backup Database

# Create backup
mysqldump -u blocked_calls_user -p blocked_calls | gzip > /backup/blocked_calls/backup_$(date +%Y%m%d).sql.gz

# Verify backup
ls -lh /backup/blocked_calls/
gunzip -t /backup/blocked_calls/backup_*.sql.gz

Restore Database

# From backup
gunzip < /backup/blocked_calls/backup_YYYYMMDD.sql.gz | mysql -u blocked_calls_user -p blocked_calls

# Verify restore
mysql -u blocked_calls_user -p blocked_calls -e "SELECT COUNT(*) FROM blocked_calls;"

Archive Old Data

# Archive 6+ months old
mysql -u blocked_calls_user -p blocked_calls << EOF
CREATE TABLE IF NOT EXISTS blocked_calls_archive AS
SELECT * FROM blocked_calls WHERE called_time < DATE_SUB(NOW(), INTERVAL 6 MONTH);
DELETE FROM blocked_calls WHERE called_time < DATE_SUB(NOW(), INTERVAL 6 MONTH);
OPTIMIZE TABLE blocked_calls;
EOF
