Although there are "prism" encryption, do not rush to deploy

After the "prism Gate" incident, more and more enterprises are paying more attention to their own information security and upgrading their defensive capabilities through powerful weapons-encryption software. However, the rapid deployment of a gun may cause various problems in the encryption project, but may affect the deployment progress and effect. We have learned from the internal network security management enterprise Overflow Information Technology Department that many enterprise network administrators and IT managers have been temporarily requested by their superiors to deploy encryption in the enterprise. They are in a hurry and lack of information, there are many problems such as lack of system planning, insufficient product selection experience, and insufficient deployment scheme feasibility. In fact, there is a set of detailed and standardized procedures for encrypted deployment. It is better to learn these five steps well, make encrypted deployment more efficient.

To effectively deploy encryption projects, enterprises should do a good job in five aspects. These five aspects are respectively determining the requirements, product selection, product testing, product deployment, and product acceptance. These five links constitute a closed loop and support the skeleton of an encryption project.

1. define your own encryption requirements

1) determine the requirements.

The determination of encryption needs must be a rigorous scientific process, rather than an impulsive result. Only by strictly following certain procedures can we ensure quality. From initial requirements to project initiation, a detailed demand survey can be conducted to help enterprises better understand their needs. The research content includes the confidential data, where the data is stored, how the data is transferred, and who can access the data, the clearer the understanding, the more favorable it will be for subsequent work.

2) rationally classify and classify requirements to clarify the key points.

Not all requirements are at the same level of importance, and the same protection effort is required. Therefore, after determining the requirements, we need to properly classify them according to their priorities. Demand is the foundation of the entire project. The more comprehensive the demand research, the more conducive to the project.

3) strive to win support from senior management to ensure smooth project development.

Many security projects fail because they did not win enough high-level support. Yixin technology security expert said that in recent years this situation has been greatly reduced, but more and more senior executives are directly involved in the deployment of encryption projects, urging IT departments to implement IT as soon as possible, improving efficiency, and accelerating the protection of Enterprise Intranet security.

2. Select an encryption product suitable for you

1) check whether the encryption technology is stable and reliable to ensure the normal operation of the system.

A good weapon should minimize its risk coefficient while maximizing its defensive performance. Encryption, as a protection tool for information leakage, must ensure stability and reliability, ensure the normal operation of the system, and ensure that Encrypted documents will not be damaged by system crash.

2) check whether the disaster recovery solution is complete enough to cope with various incidents.

Disaster recovery is an important consideration for whether an encryption system is trustworthy. The disaster recovery solution is well-developed to cope with various accidents and ensure the continuous and stable operation of the encryption system, so that users do not have to worry about the security of the original files.

3) check whether the applicable scenarios are comprehensive and fully protect document security.

If you divide the application scenarios of enterprise data, it can be roughly divided into four parts: internal document circulation, centralized management of internal application servers, outbound management, and offline office. Only when the application scenario is comprehensive can the document security be fully protected to ensure comprehensive information leakage protection for enterprises.

4) check whether the functions are rich and practical, and achieve refined management.

To achieve good results, information leakage protection must be managed in a refined manner. If you set a security policy for all data, it will inevitably cause great resistance to the business development. As a result, most of the security policies will ensure the efficiency and will not be able to continue. Therefore, when selecting an encryption system, enterprises must ensure that its functions are rich and Practical enough to meet their actual needs.

5) comprehensively consider the strength of the encryption vendor to determine whether it is trustworthy.

When considering products, you also need to comprehensively consider the vendor's strengths. Even if the product features meet your needs, your encryption project may be blocked or even fail if your company's practical experience or service capabilities are insufficient.

3. Perform full product tests

1) step by step from point to surface

During the test, many problems may occur, which may be hard to be found at the moment. If a large-area test is performed at the beginning, once the problem occurs, the tester may be unable to cope with the problem and lead to bad emotions. Therefore, it is more efficient to perform the test in the order of function test-small-scale test-extended test.

2) comprehensive examination

In addition to checking whether the product functions are up to standard, the test also focuses on product stability, ease of use, and compatibility with other programs. Products are unstable and problems occur frequently. Enterprises need to spend a lot of time to maintain them. Poor ease of use of products increases the difficulty of user operations and affects work efficiency; poor product compatibility may cause unexpected problems at any time. Actual work scenarios should be considered during the test to check the applicability of the product.

3) Timely feedback

In practice, if the company has less interaction with the manufacturer during the deployment of the encryption project, the problem may not be detected and resolved in time, or even cause unnecessary misunderstanding between the two parties. Enterprises should strictly check the effect, report problems in a timely manner, communicate with security vendors, and report problems.

4. develop feasible deployment plans

1) Pay special attention to pre-deployment research and solution formulation to minimize conflicts.

Before deploying an encryption system, enterprises should understand the ideas and needs of various departments and formulate reasonable business processes, such as deployment steps, methods, division of labor, and network topology, all possible problems should be addressed in advance, which can reduce conflicts and be prepared.

2) step by step: Client installation-enable in different regions-expand to the entire company

Even if the test is successful, you cannot take care of the deployment, because no one can guarantee that unexpected conditions will occur. Therefore, careful, step-by-step, sensitive observation and discovery are absolutely necessary.

3) sincere communication to maximize the understanding and cooperation of employees.

Non-IT staff are the subjects of encryption systems. Their attitude will determine whether the encryption system can continue to run effectively. Winning their understanding is not only to ensure the smooth implementation of security policies, but also to avoid unnecessary internal consumption.

V. Verify the Deployment Performance of the encryption system

1) Select trustworthy inspectors to ensure the results are authentic.

Objectively speaking, no one can entrust the examiner's work. A qualified examiner not only requires professional knowledge and skills, but also integrity. Enterprises must carefully select trustworthy personnel to fulfill their responsibilities.

2) perform the acceptance in stages. The previous step is passed and the next step is implemented.

First, check and accept each small phase of deployment. In this way, the problem is rectified to zero and problems are detected and solved in a timely manner. After the entire project is deployed, you also need to test the overall effect to prevent omissions. Information Leakage Protection is a continuous process, and does not need to be managed after a policy is set. Enterprises should regularly check the effectiveness of policies and make continuous adjustments to ensure their continuous effectiveness.
