What are the security implications and best practices when setting file access levels on the NAS Huawei OceanStor 5300?

Setting file access levels on the NAS Huawei OceanStor 5300 involves considering several security implications and following best practices. Here are some key points to consider:Authentication and access control: Implement strong authentication mechanisms such as username/password combinations or integration with existing authentication systems like Active Directory. Ensure that only authorized users have access to the NAS and its files.Role-based access control (RBAC): Assign users to specific roles based on their job responsibilities. This ensures that users have appropriate access rights and privileges, reducing the risk of unauthorized access or accidental data breaches.Principle of least privilege (PoLP): Follow the principle of least privilege, granting users the minimum access required to perform their tasks. Restrict access to sensitive data to only those who need it to prevent unauthorized access or data leakage.Encryption: Enable encryption for data in transit and at rest. This ensures that even if someone gains unauthorized access to the NAS or its files, the data remains encrypted and unreadable.Regular user access reviews: Conduct periodic reviews of user access rights to ensure that access levels are appropriate and up-to-date. Remove access for users who no longer require it and promptly revoke access for terminated employees.Secure file sharing protocols: Use secure file sharing protocols such as HTTPS or SFTP to encrypt data during transmission. Avoid using insecure protocols like FTP or HTTP, which can expose data to interception or unauthorized access.Network segmentation: Implement network segmentation to isolate the NAS from other network segments. This prevents unauthorized access to the NAS from other parts of the network and limits the potential impact of a security breach.Regular software updates: Keep the NAS firmware and software up-to-date with the latest security patches. Regularly check for updates and apply them promptly to address any known vulnerabilities.Data backup and disaster recovery: Implement a robust backup and disaster recovery strategy to protect against data loss or corruption. Regularly back up critical data and test the restoration process to ensure its effectiveness.Monitoring and auditing: Enable logging and monitoring features on the NAS to track user activities and detect any suspicious or unauthorized access attempts. Regularly review logs and audit trails to identify and investigate any security incidents.By following these best practices, you can enhance the security of the NAS Huawei OceanStor 5300 and protect your data from unauthorized access or breaches.

Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Huawei also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Can improper handling or maintenance of NAS Huawei OceanStor 5300 device hardware lead to data loss?

Yes, improper handling or maintenance of any storage device, including the NAS Huawei OceanStor 5300, can potentially lead to data loss. The hardware components of the device, such as hard drives, power supply units, or cooling fans, can fail if not handled or maintained correctly. These failures can result in data corruption or complete loss of data if not properly addressed. It is important to follow the manufacturer's guidelines for handling, maintenance, and regular backups to minimize the risk of data loss.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS OceanStor 5300 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

Turn off the storage and disconnect it from the power supply.

WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.
Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Overwriting during the recovery process;
Loss resulting from bad sectors;
User mistakes.

To create an image, do the following:

Make sure that you have enough free space to save the image. The image file size usually equals the disk size.
Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.
When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.
At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

Where are user’s files stored?

The Huawei OceanStor 5300 network-attached storage keeps OS Linux operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.
