1, personal safety
Important information may be leaked through electromagnetic radiation or line interference. It is necessary to design a computer room for storing top secret information, such as building a shielding room. Use radiation jammers to prevent electromagnetic radiation from leaking confidential information. For servers with important databases and real-time requirements, UPS uninterrupted power supply must be used, and the database server adopts dual-machine hot backup and data migration to ensure that the database server can provide services to external users in real time and recover quickly.
2. System security
The following strategies can be taken to prevent the security of the operating system: try to use a high-security network operating system and make necessary security configuration, close some applications that are not commonly used but have security risks, and strictly limit the access rights of some key files (such as/). Rhost, etc/host, passwd, shadow, group, etc. ), strengthen the use of passwords, patch the system in time, and keep the mutual calls in the system confidential.
In the aspect of application system security, identity authentication and audit trail record are mainly considered. Therefore, it is necessary to strengthen the identity authentication in the login process and ensure the legality of users' use by setting complex passwords; Secondly, the operator's operating authority should be strictly limited, and the operations he has completed should be limited to a minimum. Make full use of the log function of the operating system and the application system itself to record the information accessed by users and provide a basis for post-audit We believe that the adopted intrusion detection system can monitor, respond and record all access to and from the network.
Step 3: Firewall
Firewall is one of the most basic, economical and effective means of network security. Firewalls can isolate internal networks, external networks or networks with different trust domains, thus effectively controlling network access.
3. 1 Isolation and access control between provincial centers and subordinate institutions
Firewall can meet the requirements of one-way access between networks and filter some unsafe services;
Firewall can realize the secure access control of protocol, port number, time, traffic and other conditions.
The firewall has a strong logging function, which can record all unsafe access behaviors according to the policy you require.
3.2 Open the isolation and access control between the server and other internal subnets.
Firewall can realize the function of one-way access control. Only intranet users and legitimate external users can access the public server through the firewall, and the public server cannot initiate access to the intranet. In this way, if the public server is attacked, the intranet is still safe because of the protection of the firewall.
Step 4 encrypt
At present, there are generally three types of VPN services carried out by network operators:
1. Dial-up VPN service (VPDN) 2. Private VPN service 3. MPLS VPN service.
Mobile Internet VPN services should be able to provide users with dial-up VPN and private VPN services, and consider the support and implementation of MPLSVPN services.
VPN service generally consists of the following parts:
(1) service bearer network (2) service management center (3) access system (4) user system
We believe that it is the most feasible way to realize carrier-level encrypted transmission function with VPN-supporting routing equipment at this stage.
5. Safety assessment system
The existence of network system security vulnerabilities (such as lax security configuration) and operating system security vulnerabilities are important factors for hackers and other intruders to attack successfully. In addition, with the upgrading of the network or the increase of application services, new security vulnerabilities may appear in the network. Therefore, it is necessary to equip the network security scanning system and the system security scanning system to detect the security loopholes in the network, and often use, analyze and audit the scanning results, and take corresponding measures in time to fill the system loopholes and reconfigure the unsafe configuration of network equipment.
6. Intrusion detection system
In the eyes of many people, with a firewall, the network will be safe and you can sit back and relax. In fact, this is a wrong understanding. Firewall is one of the most basic, economical and effective measures to realize network security. Firewall can strictly control all access (allow, prohibit, alarm). However, it is static, while network security is dynamic and holistic. There are numerous attacks by hackers, and the firewall is not omnipotent. It is impossible to completely stop these intentional or unintentional attacks. Must ... >>
Question 2: What are the products of information security? Information security is a systematic project or project. The product you mentioned includes two parts:
1, software and hardware
2. Information security system (in fact, 1 can also be considered within the scope of 2, where system construction refers to system documents and system processes).
The core of information security is to protect the three characteristics of information, namely CIA (confidentiality, integrity and availability). All products used to protect these features are regarded as information security products. The software and hardware products purchased for this purpose can also be counted as products (various reports, table records, ISMS documents, etc. generated by ISMS operation). ) produced by consulting company.
I don't know if I made myself clear.
Question 3: What are the server security products? How to choose? There are many security products on the market now, such as Yunsuo, 360, Security Manager, Jinshan and so on. , but you need to choose according to your own situation. You can try Yunsuo.
Question 4: What are the home safety products? Top mark intelligent door magnet, nest
Question 5: What are the current automobile safety products? What you have to say is that there are additional products on the market besides the safety configuration of the car itself.
For example, you can install reversing images and radar, tire pressure monitoring, driving recorder, anti-glare rearview mirror, etc. As long as it can improve safe driving, it belongs to automobile safety products.

Chapter III Network Security Solutions
Chapter IV Typical Application Cases
Chapter V Future Development Trend of Network Security Solutions
The first chapter is the preface.
Today's network operators are experiencing an exciting information explosion era, and the network backbone bandwidth will double every six to nine months on average. As the leading service type, data service requires and drives fundamental changes in the network structure. The emergence of optical Internet has laid a new foundation for network application based on IP technology. With the popularization of network, the application of information network technology and the expansion of key business systems, the security of business systems in telecom industry has become an important issue affecting network efficiency. The openness, internationality and freedom of the Internet not only increase the freedom of application, but also put forward higher requirements for security. Due to the changes in the international situation, the possibility of cyber warfare has intensified, and ensuring network and information security is directly related to the country's economic security and even national security. Therefore, how to protect the information network system from hackers and spies has become an important issue to be considered for the healthy development of the national telecom basic network.
In the new telecom market environment, the diversification of demand and the personalization of information consumption have gradually become an inevitable trend, especially in the field of data communication. After several years of hard work, the scale and technical level of public data communication network have made a leap, the number of users has continued to grow at a high speed, and the information service users have developed particularly rapidly. The number of users in the whole country has been increasing, and they have begun to transfer to enterprise users. * * * The Internet access project is progressing smoothly, and e-commerce is fully launched. China Telecom's security certification system has passed the joint appraisal of China Password Management Committee and the Ministry of Information Industry, and has carried out effective cooperation with the financial sector. Telecom also provides Internet access service, IP telephone service and other services. IP bearer network carries the unified platform of image, voice and data, emphasizes Qos, VPN and accounting, and becomes a multi-service bearer network in the new era. The development direction of China Telecom data communication is network service and personalized service. This kind of network is actually very rich in functions, such as stored-value card business, e-commerce authentication platform, virtual private network and so on. And all this depends on the guarantee of network security. Without security, personalized service is impossible. Only when the telecommunications foundation is sound, the functions are strengthened, and the security issues are guaranteed can we provide truly personalized services.
Due to the particularity of the telecommunications sector, the transmission of important information is the basis of the entire national communication system. Its security is particularly important. Because some of our technologies are still far behind foreign countries, almost all the existing or under construction network equipment and network security products in China are products of foreign manufacturers. Only by using information security products independently developed by China and security products with independent copyright can we truly grasp the initiative of the information battlefield and fundamentally prevent all kinds of illegal and malicious attacks and sabotage. Nowadays, most computer networks base their security mechanism on the network layer security mechanism, and think that network security is only devices such as firewalls and encryption machines. With the expansion of network interconnection and the diversification of specific applications, this security mechanism is very limited for the network environment. Facing all kinds of threats, we must take effective measures to ensure the security of computer networks. We must have a deep understanding of the network, make a rigorous analysis of the security requirements, and put forward a perfect security solution. According to the specific network environment and application of telecommunication network, this scheme introduces how to establish a complete network security solution for telecommunication department.
Chapter II Overview of Network Security
Definition of network security
What is computer network security? Although this word is very popular now, not many people really have a correct understanding of it. In fact, it is not easy to correctly define computer network security. The difficulty lies in forming a comprehensive and effective definition. Generally speaking, safety means avoiding risks and dangers. In computer science, security is to prevent:
Unauthorized users access information.
Unauthorized attempts to destroy or change information
This can be restated as security is the ability of a system to protect the confidentiality and integrity of information and system resources. Note that the scope of the second definition includes system resources, namely CPU, hard disk, programs and other information.

Question 7: Special products for computer information system security What are the special products for computer information system security: antivirus, firewall, active defense, data analysis and backup, focusing on the field of confidential information security protection? In terms of information protection, the products are comprehensive.
Basis for handling special products:
1, Regulations on Security Protection of Computer Information Systems in People's Republic of China (PRC) (1February, 994 18, the State Council DecreeNo. 147).
2. Administrative Measures for Testing and Sales License of Computer Information System Security Products (1997+ 1 February, Ministry of Public Security Decree No.32).
3, "computer virus prevention and control management measures" (April 26, 2000, the Ministry of public security orderNo. 10. 5 1).
Question 8: What are the electronic product certificates for product certification?
Nowadays, no matter what industry in the world, the electronic household appliances used have passed various safety certifications (this of course does not include those products produced by "underground factories"). Why is there a safety certification? This is also a safety commitment of the manufacturer to his products, which is related to radiation, electrical safety, personal safety and so on.
Are there many signals on your monitor and computer power supply? If not, be careful, those products are not safe. Faced with all kinds of certifications and their labels, do you understand what they mean? The following is a brief introduction to some of the most common security certifications in the computer information industry, hoping to be helpful to your future hardware procurement.
CCC certification
China's compulsory product certification was implemented on May 1 2002. The name of the certification mark is "China Pulse Certification" (abbreviated as "CCC"). The products listed in the catalogue of the first batch of products subject to compulsory product certification issued by the General Administration of Quality Supervision, Inspection and Quarantine and the National Certification and Accreditation Administration shall be subject to compulsory inspection and audit.
Where the products listed in the catalogue have not been certified by designated institutions and have not been marked with certification marks as required, they shall not leave the factory, import, sell or be used in business service places. After the compulsory certification mark is implemented in China, it will gradually replace the Great Wall mark and CCIB mark. The original "Great Wall" logo and "CCIB" logo were abolished on May 1 day, 2003.
CCEE certification
The certification mark of CCEE-Great Wall Mark China Electrical Product Certification Committee (CCEE) was established in 1984, and its English name is China Electrical Product Certification Committee (hereinafter referred to as CCEE). It is the only organization representing China in the International Electrotechnical Commission's Electrical Product Safety Certification Organization (IECEE) and the national certification body in the field of electrical products in China. CCEE has four subcommittees: electrical equipment, electronic products, household appliances and lighting equipment. Has been abolished.
CCIB certification
CCIB is the abbreviation of China National Import and Export Inspection Bureau. The safety and quality licensing system for imported goods is a safety certification system for imported goods implemented by the State Import and Export Commodity Inspection Bureau (SACI). All goods listed in SACI import safety and quality licensing system must pass product safety type test and factory production and testing conditions review. After passing the inspection, they are allowed to export and sell to China only after being affixed with CCIB commodity inspection safety signs. Common in genuine imported equipment and electrical appliances. Has been abolished.
Ce certification
Nowadays, CE marks are used more and more, and products with CE marks show that they meet the requirements expressed by a series of European directives such as safety, hygiene, environmental protection and consumer protection. CE stands for obedient Europe. CE is limited to the basic safety requirements of products that do not endanger the safety of human beings, animals and goods, rather than the general quality requirements. This is a standard task.
If the product meets the main requirements of relevant quality, CE mark can be attached instead of judging whether CE mark can be used according to the relevant standards of general quality. Therefore, the accurate meaning is that the CE mark is a safety qualified mark rather than a quality qualified mark.
CQC product quality certification
The name of CQC organization is China Quality Certification Center, and now CCC certification is compulsory in China. Obtaining the CQC product certification certificate and affixing the CQC product certification mark means that the product is certified as safe by the national certification body and meets the quality standards of the national response.
CSA certification
CSA is the abbreviation of Canadian Standards Association. Established in 19 19, electronic and electrical products sold in the North American market need to obtain safety certification. At present, CSA is the largest safety certification body in Canada and one of the most famous safety certification bodies in the world. It can provide safety certification for various products in the fields of machinery, building materials, electrical appliances, computer equipment, office equipment, environmental protection, medical fire safety, sports and entertainment.
