How do software companies prevent source code leaks?

The company's terminal file data transparent encryption anti-leakage software system——Derenhe TechnologyProvide software system and technical support.

Scope of application. The document security system is suitable for enterprises, enterprises, military, finance, communications, insurance, justice, individuals and other units and individuals with various data confidentiality needs.

The use of the document security system will not affect the original operation habits of the operator, and the confidential environment is simple to establish and easy to manage. It is an ideal solution for enterprise file encryption and data confidentiality.

There are two versions of the file encryption system: stand-alone version and network version. Web-based document security system.

Based on the enterprise LAN environment, the client user is responsible for encrypting the electronic file, and the server user is responsible for the management of the client user, the tracking of the operation of the client user, and the decryption of the encrypted file.

The document security system supports mainstream operating systems such as Windows, macOS, and Linux, and can encrypt files in any file format specified by the user.

Basically, it depends on self-awareness, after all, if the developer doesn't touch **, then what else is there to develop. Now that I've come into contact with it, it's my choice to leak secrets or not, and I'll copy and paste it back if the remote server can't ftp down, and I'll take a screenshot if I don't let me copy and paste, and I'll take a picture if I don't let me take a screenshot, and I'll copy it by hand if I don't let me take a picture, and it's impossible to put an end to it.

Some companies will use some confidential software, which basically means that a confidential disk space is opened up as a territory for all developers, which can be copied out, and all the data outflow in this space will be encrypted, and you can copy it back and decrypt it.

There are also companies that directly use IBM's full set of systems, develop and test machines, all file transfer and sharing services are closed, only telnet, no external network, software **can't, only its own vi, not even vim, remote login used to kill you once you see 30 lines, the entire machine hundreds of trillion sources ** are coders word by word type, the machine is full of all kinds of development shell scripts written by everyone. Colleagues went out to work, and when they saw other yards, agricultural flowers and greens, large screens, split screens, ide Shenma, knocked on **, and they were in a hurry.

Clause.

1. Restrictions on division of labor and management: use good source code version control, and divide technical staff according to their responsibilities and permissions according to the needs of the project, such as project managers, architects, and general programmers. The average programmer can only access the part he is responsible for, and he can't view what others write.

It can prevent low-level employees from taking all the source code after leaving.

Clause. Second, the use of special encryption software, such as the source code to encrypt, after leaving the post machine, the copied source code is garbled; At the same time, the use of network transmission and USB flash drive is restricted. Similar software seems to be available on the market, and it's not cheap. It seems to be useful for the average technician, but it's not too difficult for people who are very eager to take the source code away.

The most typical is that when someone leaves their job, they even take a lot of trouble to take a picture of the screen with their mobile phone, how do you use these facilities to prevent it?

Clause. 3. Use the law to defend their intellectual property rights, apply for patent protection and property rights protection of their source code in a timely manner, and resort to law against employees who maliciously take away the source code. You can kill chickens to show monkeys, scare and scare employees.

Clause. Fourth, the underlying and commonly used core ** are packaged and encapsulated, and non-core personnel call dll for use every time they develop knowledge, which can prevent the core ** from being easily leaked.

Clause. 5. Improve corporate treatment and employee satisfaction, and reduce employee turnover, especially core employees and key employees. For an enterprise, the departure of a core member and key members is a great loss for the enterprise. If these core employees, or even the project manager, leave, as long as he wants, your ** will always return.

It's nothing more than a matter of time. He can copy it, or he can take the time to rewrite it by himself based on his knowledge and mastery of the project.

Clause. Sixth, do not let technical personnel contact the business. This can effectively reduce turnover and carry ** resignation. In particular, it is necessary to minimize the profit problem of the technical base to the business, and the excessively high profit can induce anyone to appear to think about replacing it.

Clause. Seventh, for small enterprises and small teams, the division of labor can not be clear, version control can not be perfect, the cost of resorting to law is too high, often the core personnel and ordinary personnel are one person, not to contact the business is often unrealistic, the best way is to sign a confidentiality agreement, and at the same time put the core technical staff into shares, their own company into everyone's company. There is no need for him to leave his job.

Source**Encryption software is recommendedDerenhe TechnologyGreen Shield encryption software.

It is a software system that ensures data security and use security from the source. It adopts a file transparent encryption module, which has no impact on ordinary office use. Moreover, Green Shield supports seamless integration with source** management tools such as SVN.

If the internal SVN server adopts the transparent mode, that is, encrypted files can be stored on the SVN server, and the effect needs to be achieved is that the files on the SVN server are stored in ciphertext. It cooperates with the Serui Green Shield application server security access system to realize that only Windows, Linux, and Mac terminals with encrypted clients can access the company's internal SVN server normally.

If the enterprise uses development tools such as Eclipse and VS, it will be automatically decrypted when the ** is uploaded directly to the SVN server from these development tools. In order to avoid problems such as errors in version comparison caused by chaotic storage of plaintext and ciphertext. Therefore, plaintext files need to be stored on the SVN server.

The server whitelist function realizes the mandatory transparent encryption of the terminal computer data, and realizes the automatic decryption and automatic encryption of the uploaded data uploaded to the application server. In addition, with the secure access system of the Venus Green Shield application server, only the Windows, Linux, and Mac sides with the encrypted client installed can carefully judge the normal access to the company's internal SVN server.

Derenhe Technology

Provide customers with high-quality intranet security management products and application solutions suitable for a variety of industries.

The general beta version of the system is not leaked.,It's officially released.,Only the round cherry blossoms are defeated, but some people like to try it.,Just do the guinea pig for the official experiment to see what bugs the new system has.,People who like to be stable and don't like tossing.,Still use the old version of the system.。

1.On the basis of the hierarchical permissions of developers, device security management is added. Not all of them are accessible on every device**.

2.Increase data storage encryption measures. So that a lot of ** can only run on the machine, copying, email sending are passwords, and the recipient can't.

3.Added transmission encryption function. Prevent people with ulterior motives from intercepting the source through the link and causing leakage.

4.Added permission control such as destruction and product version launch. Prevent unexpected program downtime and errors such as database crashes.

5.The log audit function and alarm function are added. Timely detection of leakage problems and traceability of leakage.

Improve your company's rules and regulations, and only a few people are responsible for the core documents and sources, so that people can be held accountable for leaks. Employees sign a confidentiality agreement before joining the company, and use software such as Zhongke Security Enterprise to encrypt confidential documents and sources so that they can only be previewed and used in the company's local area network. Use the software to set the read and write settings of the USB flash drive so that it can only perform read operations and cannot write.

1. Employees sign confidentiality agreements, and daily confidentiality codes of conduct should be done.

2. Virtual desktops can be used, which can reduce some of the risk of leakage.

3. It is best to deploy mature anti-leakage software to protect enterprise sources from three measures: encryption, behavior audit, and permission control.

IP-Guard is recommended

IP-Guard has a transparent encryption function based on the driver layer, and can also audit most of the leakage channels, based on the triple protection measures of transparent encryption, behavior audit, and permission control, it can build a complete anti-leakage system for enterprises.

IP-Guard was founded in 2001 and has been providing leak-proof solutions to more than 20,000 world-renowned companies for more than 10 years.

In addition to automatically encrypting and protecting various sources, it can also prohibit external mobile storage devices from accessing the enterprise intranet, and the operation behavior of the source can be monitored in detail, and the source of the leak can be found immediately once the leakage occurs.
