Drainage system and safety measures design of petrochemical enterprises?

Therefore, when designing such a circulating water supply system, the pressure balance of the supply and drainage pipes should be carefully considered, and corresponding technical measures should be taken at the inlet and outlet water pipes to ensure the safety and reliability of the system operation.

The maximum rainfall is determined in accordance with the Outdoor Drainage Design Specification (GB50014-2006) and the Design Specification for Water Supply and Drainage Systems of Petrochemical Enterprises (SH3015-2003), etc.

The riser of the special single risor drainage system, its pipe fittings and pipe materials can be freely combined, and the special pipe fittings can be configured with ordinary drainage pipe materials; special pipes can be configured with ordinary drainage pipe fittings;Special pipe fittings can also be configured with special pipes. The deflection blades or spiral ribs of special pipe fittings and the spiral ribs of spiral tubes should be counterclockwise.

What factors should be considered in the design of the security prevention system

Security system design in In the early stage of office decoration, we should consider integrating the security system into the overall design.This includes the planning of the camera position, the installation position of the sensor, the arrangement of the access control system, etc. Ensure that the security equipment is reasonably arranged, which can provide comprehensive monitoring coverage and ensure the security of the office.

Meet the security and electromagnetic compatibility requirements of the system. Electromagnetic compatibility refers to the ability of a device or system to run in accordance with the requirements in its electromagnetic environment without causing unbearable electromagnetic harassment of any equipment in its environment. Meet the reliability, repairability and maintenance guarantee requirements of the system.

Designed by factors such as scale, maintenance and police reception method. The design of the system should meet the requirements of the relevant risk level and protection level standards, and meet the relevant design specifications, design tasks and the management and use requirements of the construction party. Equipment selection should meet the requirements of relevant national standards, industry standards and relevant management regulations.

On-site survey is the basis of design. Therefore, it is necessary to conduct an "on-site survey" before the design of the security prevention system. For new projects or projects that cannot be surveyed on site, it can be omitted.

design steps of the security system

1. Finally, the credibility certification of the security operating system. After the design of the security operating system is completed, repeated testing and security analysis should be carried out, and submitted to the authoritative evaluation department for security credibility certification.

2. Designing a capital security framework, formulating a capital security strategy and establishing a capital security management mechanism are only the first steps to implement a capital security system. Only when organizations at all levels can strictly implement the provisions of fund security and conscientiously maintain the fund security of their respective sub-systems can they ensure The overall security of funds.

3. Clarify the needs: clarify the needs and expectations of customers, including functional requirements, performance requirements, security requirements, etc. Code writing: Write code according to the system design document to realize the functions required by the system. Make a plan: Make detailed plans and schedules according to the results of demand analysis in order to provide guidance for follow-up work.

4. Audit of information security management system. System audit is a systematic, independent and document inspection process carried out in order to obtain audit evidence and make an objective evaluation of the system to determine the degree to which the audit criteria are met. System audit includes internal audit and external audit (third-party audit).

5. After the requirements analysis, enter the system design stage. This step needs to be determined according to the results of demand analysis.The implementation method of the alarm system, hardware and software equipment, sensors and controllers, etc., including the transmission and reception methods of alarm signals.

6. Establishing a complete information security management system usually requires four steps: planning, implementation, inspection and improvement. Information security management system is a system in which organizations establish information security policies and goals within a whole or specific scope, and the methods used to achieve these goals.

What are the design principles of information security system?

1. Principle 1: "Barrel Principle", that is, to protect information in a balanced and comprehensive manner. The volume of the barrel depends on the shortest wooden board", the attacker must attack in the weakest part of the system.

2. The main principles of information security protection system design are implementability, manageability, scalability, comprehensive completeness, system balance, etc. Each system unit in the framework structure corresponds to a certain protocol level, and several security services need to be adopted to ensure the security of the system unit.

3. Prevention is the main principle: In the planning, design, procurement, integration and installation of the information system, information security issues should be considered simultaneously, and information security issues should not be taken by chance or made up for it after the fact.

4、. The Country-specific HS code conversion chartsprinciple of standardization and consistency. The system is a huge system project. The design of its security system must follow a series of standards, so as to ensure the consistency of each subsystem, so that the whole system can be safely interconnected and information is shared.

5,The principle of minimum privilege The principle of minimum privilege refers to the assignment of rights to the subject in accordance with the principle of minimizing the rights required by the subject when the subject performs the operation. The principle of minimum leakage The principle of minimum leakage refers to the allocation of rights to the subject in accordance with the principle of minimizing the information that the subject needs to know when the subject performs the task.

Some suggestions for system security design

That is, through the setting of VPD, we can achieve row-level security control. Even if a specific user has the right to read a table, he can only see what is in line with himself. The record of permissions. Note that in the Oracle10g version, VPD has been enhanced to achieve field-level security control.

The design should be strictly followedAccording to the "Design Specification for Automatic Water Sprinkler Fire Extinguishing System", according to the special circumstances of thermal power plants, automatic water sprinkler fire extinguishing systems are installed in places that are more prone to fires, such as transformer areas, coal yards, coal mills and boiler rooms, coal trestles, etc.

It's better to install a waf, which can prevent various problems to a certain extent. Use pdo to query the database. The database permission should not be too high, and the station library should be separated. Sensitive paths such as background should be hidden, or IP should be verified. If the station library cannot be separated, the upload directory, etc. must be set: prohibit the execution of any scripts.

What are the benefits of the security system design of the OA system

The value of the OA early warning system: OA system project early warning can be realized: find problems at the first time, release early warning information, reduce losses and make up for shortcomings in time;The early warning processing process can be tracked to improve project efficiency and solve problems quickly; mobile early warning problem processing, fragmented time can be used, and feedback can be provided at any time.

Improve work efficiency By establishing a unified office management platform, the OA office system can really implement the organization's system, make employees' behavior more standardized and efficient, and improve the execution of enterprise employees.

Access level security authentication system: CA certification system can support a variety of strong security identity authentication methods such as certificate authentication to solve the security risks of weak passwords.

What are the benefits of using the OA system for enterprises? Improve office efficiency and automate workflow. The approval and processing of official documents require close contact and coordination between departments.

In the digital era, information security is very important.The OA system protects sensitive information from unauthorized access through permission control, data encryption and other technologies. At the same time, the storage and backup of data in the system also help to deal with risks such as data loss and disaster recovery.

The advantages of enterprises using oa office systems are: automation. It is very difficult to retrieve documents in manual office. The OA office automation system enables the electronicization of various documents, realizes the custody of documents in the form of electronic file cabinets, and uses and shares them according to permissions.
