The potential for long-term damage to customer trust in the M&S brand is also substantial.

• Multi-factor authentication for all systems: This adds an extra layer of security, making it significantly harder for attackers to gain unauthorized access.
• Employee training on phishing and social engineering tactics: Educating employees about these threats is crucial in preventing attacks.
• Data encryption and secure data storage practices: Encrypting data both in transit and at rest protects it from unauthorized access, even if a breach occurs.
