| Risk | Mitigation in this project | |---------------------|-----------------------------------------------| | SQL Injection | Prepared statements / mysqli escape | | Password leaks | password_hash() & password_verify() | | Double voting | Database flag + session check | | Session hijacking | Regenerate session ID after login | | XSS | htmlspecialchars() on output |

Here’s how to download and run the portable online voting system PHP MySQL project from GitHub.

| Column | Type | Description | |--------------|--------------|-------------| | id | INT (PK, AI) | Vote record ID | | voter_id | INT (FK) | References users(id) | | election_id | INT (FK) | References elections(id) | | candidate_id | INT (FK) | References candidates(id) | | voted_at | TIMESTAMP | Prevents replay attacks |

Unique constraint: (voter_id, election_id) ensures one vote per election per user.

This schema is portable because it uses standard SQL; you can export it as voting_system.sql and import it on any MySQL server (5.7+ or MariaDB).
