Which method would NOT be considered effective against data breaches?

Weak access controls would not be considered effective against data breaches because they represent a significant vulnerability in an organization's security posture. Strong access controls are essential for protecting sensitive data from unauthorized access. This involves implementing measures such as robust authentication mechanisms and ensuring that users have the minimum necessary access privileges required to perform their job functions.

On the other hand, strong encryption is essential for safeguarding data at rest and in transit, making it difficult for attackers to access or decipher the information even if they manage to breach a system. Regular software updates are vital for patching known vulnerabilities that could be exploited by attackers, thereby reducing the risk of a data breach. Employee training plays a crucial role in ensuring that staff are aware of security best practices, such as recognizing phishing attempts and following proper data handling procedures. All these methods contribute to enhancing security, while weak access controls directly undermine these efforts by opening up potential entry points for attackers.
