What is SSH and how does it work in the context of network security?

SSH stands for Secure Shell, which is a network protocol used for secure communication between two computers. It provides a secure channel over an unsecured network, such as the internet, allowing users to log into remote systems and execute commands securely.In the context of network security, SSH plays a crucial role by providing encryption and authentication mechanisms. Here's how it works:Encryption: SSH uses encryption algorithms to secure the communication between the client and the server. It encrypts all the data transmitted over the network, including passwords, commands, and file transfers. This prevents unauthorized access and eavesdropping by encrypting the data in transit.Authentication: SSH uses various authentication methods to verify the identity of the user before granting access to the remote system. The most common method is password-based authentication, where the user provides a username and password to log in. However, SSH also supports more secure authentication methods, such as public key authentication, where the user generates a key pair (public and private key) and shares the public key with the server. The server then verifies the user's identity by matching the private key with the public key.Port Forwarding: SSH allows port forwarding, which enables secure access to services running on remote systems. It creates an encrypted tunnel between the local and remote systems, forwarding specific ports or protocols securely. This feature is useful for accessing services like databases, web servers, or remote desktops securely over an untrusted network.Secure File Transfer: SSH includes a secure file transfer protocol (SFTP) that allows secure file transfers between the client and the server. It ensures the confidentiality and integrity of the transferred files, preventing unauthorized access or tampering.Overall, SSH enhances network security by providing secure remote access, encrypted communication, strong authentication, and secure file transfers. It is widely used by system administrators and IT professionals to manage and secure remote systems.

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 Infortrend also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

What are the common causes of data loss in NAS Infortrend EonStor GSe Pro 1004 devices?

There are several common causes of data loss in NAS Infortrend EonStor GSe Pro 1004 devices, including:

Accidental deletion: Users may accidentally delete important files or folders, leading to data loss. This can happen due to human error or improper file management practices.
Software corruption: Corruption of the NAS operating system or other software can result in data loss. This can occur due to malware or viruses, improper shutdowns, or software bugs.
Power outages: Sudden power outages or fluctuations can cause data loss if the device is not properly protected with backup power or surge protectors. Power loss during read or write operations can result in data corruption or loss.
Natural disasters: Events such as floods, fires, earthquakes, or other natural disasters can physically damage the NAS device and result in data loss.
Theft or physical damage: If the NAS device is stolen or physically damaged, data loss can occur. It is important to have proper security measures in place to protect the device from theft or damage.
User error: Users may unintentionally modify or delete important files or folders, leading to data loss. This can happen due to lack of knowledge or training on how to use the NAS device properly.

To minimize the risk of data loss, it is recommended to regularly backup data from the NAS device to an external storage or cloud storage solution. Additionally, implementing proper security measures, such as firewalls and antivirus software, can help protect against malware and viruses.
