There are several strategies to protect against rainbow table attacks:
Use Salt: Adding a unique salt to each password before hashing it makes rainbow tables less effective. The salt ensures that even the same passwords will have different hash values. Strong Hashing Algorithms: Employing strong, slow hashing algorithms like bcrypt, scrypt, or Argon2 can mitigate the risk, as they are more resistant to rainbow table attacks. Regular Security Audits: Conducting regular security audits can help identify potential vulnerabilities in your email marketing system and address them promptly.
