Final answer:
The true statement about secure data storage on a network is that backing up data is crucial to prevent data loss. Regular data encryption and password updates are fundamental security measures, while sharing sensitive information publicly undermines security.
Step-by-step explanation:
When addressing the question of secure data storage on a network, the true statement among those provided is C. Backing up data is important to prevent data loss. First and foremost, data encryption is absolutely essential for secure data storage. It transforms readable data into encoded data that can only be accessed or decrypted by those possessing the necessary key or password, safeguarding the information from unauthorized access.
Additionally, regularly updating passwords is a critical security measure. Updating passwords frequently helps to protect against unauthorized access, especially in the event that a password has been compromised. Implementing strong, unique passwords and changing them periodically augment a network's security strength.
Moreover, backing up data is indispensable for data security. It ensures that in the event of a system failure, cyber-attack, or other data loss scenarios, the information is recoverable from a backup source, thereby maintaining continuity of operations and avoiding a total loss of critical data. It is a fundamental aspect of a robust data management strategy.
Lastly, publicly sharing sensitive information does not enhance security. In fact, it does the opposite by exposing the information to potential threats and increasing the risk of it being misused. Sensitive information should always be handled with the utmost care and shared only on a need-to-know basis while ensuring that all security protocols are strictly followed.
In conclusion, among the options presented, only the necessity of data backups is true for secure data storage on a network. Other options either misrepresent best practices or suggest dangerous actions that would weaken data security.
