The information system of an enterprise is inevitably threatened by external security, including natural disasters, networks, hardware and software. And human error. Any mistake in data storage may bring huge economic losses to enterprises.
With the increase of data value and the development of storage network, the security threats faced by data are increasing day by day. Without storage security precautions, once an attacker successfully penetrates into the data storage system, its negative impact will be immeasurable. This requires enterprises to fully consider storage security under a specific storage system architecture. The most common storage security problems faced by enterprises in the process of business operation are mainly caused by natural disasters, network, hardware and personnel operation errors.
Natural disasters lead to data storage security.
First of all, this is not a man-made behavior. A large amount of data is stored in the server storage system of the enterprise. In the process of data transmission, data loss caused by power failure or sudden short circuit is a great loss for enterprises. In this state, the loss of enterprise data caused by natural disasters can be said to be a great security threat to enterprise data information. The normal operation of the system, the reasonable optimization of the database and the perfect operation process of the operators ensure the stability and security of the data, but sudden power failure, fire and insufficient standby power supply are often problems faced by small and medium-sized enterprises. At the same time, data storage security has become a problem that must be solved in the face of this situation, and it is also a measure that enterprises need to take in time to ensure data security. But how to deal with the storage security of enterprise data in the face of this situation?
Network hardware
Secondly, the problems in the hardware environment of enterprise data will also lead to data security problems in the storage process. As we all know, with the rapid development of information technology and the rapid upgrading of hardware, the traditional storage environment of enterprises is difficult to cope with the massive data demand today, and enterprises have to upgrade to meet the requirements of the current data storage environment. The aging of hardware environment leads to the decline of transmission rate, and the optimization of network also needs a good hardware environment as the foundation. If the amount of data in the process of data transmission is too large, the hardware environment of the enterprise will not be improved, and the network delay will lead to system collapse, resulting in huge economic losses. For these aspects, enterprises need to upgrade the configuration of storage servers according to the needs of business development, improve the benign environment of the network, and ensure the data security during storage.
Operator's operation error
"No gold is perfect, no one is perfect" is a wise saying for the data managers of any enterprise today. Everyone will inevitably make mistakes or operational mistakes in the process of work, especially those engaged in database management. Large amount of data and complicated system operation will bring unnecessary errors to the work, thus threatening the security and integrity of enterprise data. At the same time, the data managers of small and medium-sized enterprises are also responsible for the operation and maintenance of the storage system, which puts forward higher requirements for the security of their data storage process. Facing the problem of data security in the process of enterprise storage, how to solve it and what measures to take to ensure data security are the main problems faced by every enterprise. Data is the core of enterprise operation, and strong data support ensures that enterprises ride the wind and waves in the market. Here is how to solve the data security problem in the stored procedure.
Generally speaking, enterprises can adopt various schemes to solve the problem of data security during storage: remote backup can avoid data loss when natural disasters occur; RAID (Redundant Array of Independent Disks) can reduce the damage of disk components; Using mirroring technology can reduce the damage of storage devices; Snapshots can quickly restore damaged data and reduce downtime losses. The adoption of these technologies can well deal with the data security problems caused by natural disasters, network, hardware and personnel operation errors faced by enterprises.
Remote backup
Remote backup is the safest way to protect data. No matter what natural disasters, even fires and earthquakes, when other means of protecting data fail, the advantages of remote disaster tolerance are reflected. The problem of remote backup lies in the speed and cost, which requires a network connection with sufficient bandwidth and excellent data replication management software. Generally, there are three main aspects to realize remote backup. Firstly, based on the disk array, the data replication between the disk arrays is realized through the software replication module. This method is suitable for using the same disk array at both ends of replication. The second is based on host mode, which has nothing to do with disk array. Third, it is based on storage management platform, which has nothing to do with host and disk array.
assault
RAID systems use many small-capacity disk drives to store a large amount of data and enhance reliability and redundancy. To a computer, such an array is like a logical unit composed of multiple disk drives. The common feature of all RAID systems is "hot swap" capability: users can take out defective drives and insert new ones to replace them. For most types of RAID, the data on the failed disk can be automatically reconstructed without interrupting the server or system.
mirror image
This technology aims to mirror different volumes or remotely mirror different volumes when the branches in different places fail, or to automatically take over the single-point failure machine by adopting the dual-machine fault-tolerant technology, so as to ensure that the mirrored equipment with the same environment and content in different places can still be started when there is no single-point failure and the local equipment encounters unrecoverable hardware damage, thus ensuring uninterrupted service. Of course, this will inevitably increase the investment in equipment.
snapshot
In data protection technology, snapshot technology is one of the most basic and popular technologies, which is applied to many storage processes, such as data replication and backup. FlashCopy of IBM, PSM software of IBM NAS and FlashSnap software of VERITAS are all representatives of snapshot technology. Snapshot can quickly recover damaged data, reduce the loss of downtime, and can recover data against the mistakes made by database managers in operation.
Summary:
There are many solutions to the data security problems in enterprise storage process. Although storage security is very important, storage security is only part of the overall security solution for data centers. Safety is a topic with wide connotations. Storage does not play a leading role in business processes, but it does play a key role because storage contains most of the company's records. Without storage, many business processes cannot continue. Therefore, every enterprise should pay attention to the data security in the storage process and put more energy into it. Data is the core competitiveness of enterprises, and safe and powerful data is the guarantee for enterprises to take off. The development of storage technology and the improvement of hardware environment will undoubtedly provide strong support for enterprise data security.
