The functions of modern computer systems are becoming more and more complex, and the informatization is becoming more and more powerful, which is having a huge and far-reaching impact on all walks of life in society, but at the same time, due to its openness, security issues are becoming more and more prominent. However, as people rely more and more on computer networks, information security is becoming more and more important. To prevent different types of system security risks, it is very important to build a secure system.
server configuration
1. Install antivirus software
The harm of computer virus is increasing day by day, we must install anti-virus software on the server.
2. Turn off unnecessary services
After installing the application system, we should disable any network service programs that the server does not undertake.
3. Make security settings for the system account
Some company administrators often use the company name and computer name as user names when creating accounts, and then set the passwords of these users too simple, such as "welcome" and so on. Therefore, pay attention to the complexity of the password, and remember to change it frequently.
4. Close unnecessary ports
Use a port scanner to scan the open ports of the system, determine which ports are open, and close unnecessary ports.
cyber security
The security protection of network communication and access is mainly to ensure that information is safely transmitted on the network, to ensure the legitimacy of visitors who access open source byte application systems and data information through network lines and equipment, and to ensure that internal data information of the enterprise is not compromised by outsiders. stolen by the attacker.
1. Use a firewall
Firewalls are widely used in ensuring network security. In organizations connected to the Internet, it is often used to protect intranets and resources. Firewalls can also be used to restrict access to confidential information or other sensitive information in intranets, so that only limited authorized operations can pass through the firewall.
2. Use VPN technology
The VPN based on the public network enables the remote users of the enterprise to quickly access the internal network of the enterprise under the premise of safety through the tunnel technology, data encryption technology and QoS mechanism, so as to realize related operations on the internal network.
3. Use SSL security mechanism
- Use encryption technology to establish an information security channel to ensure the security of data transmission;
- Verify the identity to confirm the authenticity of the website;
- Ensure data integrity and prevent content from being impersonated or tampered by a third party
Data Security
Our system supports MySQL7 and above versions. For the database, data security is mainly reflected in the following aspects:
1. Use the security account to establish the management of the application database
Account, through the authority system of the database, assign the specified operation authority to the management account to prevent the loss of database data due to misoperation.
In the management of our software, user management and authority are combined with database security management to the greatest extent to ensure data security.
2. Use a secure password policy
The password of the database user is too simple, which is one of the main reasons for being attacked. The password of the database user must use a combination of characters, numbers, and symbols, which is as important as the password of the system user. More attention should be paid to the administrator's password, which should be changed regularly.
3. Automatic data backup
While creating the database, we will create system tasks and backup plans, and automatically perform data backups every day to prevent data loss due to factors such as database damage, and you can use backups to restore data. The default policy is to back up once a day at noon and at night to improve the fault tolerance rate of system data.
software security
The software security design provided by the system includes function permission setting, data permission setting and operation log management, as well as design to prevent system crash.
1. Function permission setting
The range of functions used by each individual can be set.
2. Data permission setting
You can control the scope of each person viewing and modifying data, for example, some data can only be viewed but not modified. For the allocation of rights, the method of dividing roles is adopted to realize the setting and maintenance of batches of personnel rights.
3. Operation log management
It is the application system that automatically records in detail every step of each operator's operation from entering the system to exiting the system, which day, what time, and what operation was performed. When a problem occurs, it can play a role in finding the cause.
Through the system application layer, the management and supervision of each operator's use range, use time, and how to use can be realized.
4. Prevent system crash
Unreasonable system design will also lead to system crashes. In this regard, we have done a lot of optimization design, such as limiting the upper limit of a single imported data when importing business data, reducing unnecessary large-scale data operations, and optimizing JVM server parameter configuration , to prevent system downtime caused by memory overflow.
