Here is what you need to know.
TOS 5 Now has a Secure HyperLock-WORM file system Option
Data is a precious asset of the vast majority of users, and data security is very important! Some data storage and custody are even regulated by law, such as court cases, medical cases, financial securities, company financial data, etc. These important data can only be read but not written within a specified time period according to the law. Therefore, such data needs to be protected against tampering. The WORM (Write Once Read Many) features provide a write-once-read-many technology, which is a commonly used method for data security access and archiving in the storage industry. The WORM feature means that after the file is written, it can enter the read-only state by removing the write permission of the file. In this state, the file can only be read and cannot be deleted, modified, or renamed. By configuring the WORM feature to protect the stored data, it can be prevented from accidental manipulation.
TerraMaster HyperLock-WORM file system is a storage system with WORM characteristics. Through the write-once-read-many technology, the integrity, confidentiality, and accessibility of the original data in the storage medium are guaranteed to satisfy the sensitive requirements of enterprises. Data security storage and legal supervision needs. The characteristic of the TerraMaster HyperLock-WORM file system is that its WORM feature is developed based on the file system and is not limited by the file service type. It is suitable for most common file services, but can only be set by the administrator. Administrators can flexibly assign read and write permissions to users and set a protection period. During the protection period, the data uploaded to the device can only be read and cannot be deleted, modified, or renamed. The protection period can be set up to 70 years! In order to improve security, once the protection period is set, it can only be extended but not shortened.
Compared with other storage solutions with WORM features, the TerraMaster HyperLock-WORM file system has higher security. Once the TerraMaster HyperLock-WORM file system is created, even the administrator cannot delete or modify the storage partition from the menu page or the system background. As long as the storage device is safely placed in an isolated environment, anyone without access to the NAS hardware devices, even employees with administrator privileges or hackers, cannot pose a threat to the data. TerraMaster HyperLock-WORM file system is an innovation in data security management, which can provide more secure protection for customers’ important digital assets, and is suitable for industries with important data such as government, public health, law, finance, and enterprises.
