Data storage system security challenges
1. Hardware failure
Hardware failure refers to the downtime caused by the failure of the server equipment and the inaccessibility of the data system or the massive loss of data caused by the failure of the data storage medium, thereby affecting the availability and security of the data. This type of failure has the lowest probability, but is extremely destructive.
2. System failure
System failure refers to any event that causes the system to stop suddenly, requiring the system to restart or fail to start, including various types of hardware errors, system program damage, and sudden power outages. This kind of failure affects all transactions that the storage system is running, and is not destructive to the existing original data, but due to the abnormal suspension of transactions, it is very likely to cause the loss of new data or the inconsistency of modified data. The database is in an incorrect state.
3. Database program failure
Database program failure means that the database cannot be accessed or is restricted due to software system failure and the operating speed is abnormally reduced, which affects the availability of data and the continuity of business programs.
4. Computer virus
Computer viruses are malicious programs that artificially damage the system and the normal operation of data. They can quickly spread like microorganisms, which affects the availability and reliability of data.
5. Illegal attack or misuse
In the intranet, access to information resources is usually only authenticated by user name + password. Once an authorized user has obtained the user name and password of an authorized user, they can access the network server resources, which can easily cause unauthorized data changes. In addition, internal personnel attacking the database and misuse within the authority will cause damage to the data storage system.
In addition to the above-mentioned threats, data storage systems also include many other types, such as power failures, natural disasters, and strong electromagnetic interference. Therefore, the security prevention of data storage systems and disaster recovery mechanisms are essential.
