1, physical security
For important information may be leaked through electromagnetic radiation or line interference and so on. Need to store top secret information on the machine room necessary design, such as the construction of shielding room. The use of radiation interference machine to prevent electromagnetic radiation leakage of confidential information. Important databases and real-time *** requirements of the server must be used UPS uninterruptible power supply, and database servers using dual hot backup, data migration and other ways to ensure that the database server real-time external users to provide services and can be quickly restored.
2, system security
For operating system security can take the following strategies: try to use a higher security network operating system and the necessary security configuration, close some of the application is not commonly used but there are security risks, some of the key files (such as UNIX: /.rhost, etc/host, passwd. shadow, group, etc.), The system can be used in a variety of ways, including: (1) to create a new system, (2) to create a new system, (3) to create a new system, (4) to create a new system, (5) to create a new system, (6) to create a new system, and (7) to create a new system.
Application system security, the main consideration of identity authentication and audit trail records. This must strengthen the login process of identity authentication, through the setting of complex passwords, to ensure the legitimacy of the user's use; secondly, should strictly limit the login user's operating privileges, the operation will be completed in the smallest possible range. Make full use of the logging function of the operating system and application system itself to record the information accessed by the user, so as to provide a basis for review afterwards. We believe that the use of intrusion detection systems can be used to enter and exit the network of all access to carry out good monitoring, response and make records.
3, firewall
Firewall is one of the most basic, most economical and effective means of network security. Firewall can realize the internal, external network or different trust domains between the network isolation, to achieve effective control of the role of network access.
3.1 Isolation and Access Control between Provincial Center and Subordinate Institutions
The firewall can achieve one-way access demand between networks and filter some unsafe services;
The firewall can achieve safe access control for protocols, port numbers, time, traffic and other conditions.
The firewall has a strong logging function, which can record all the insecure access behaviors for your required policies.
3.2 Isolation and access control of public servers and other internal subnets
The firewall can be used to achieve unidirectional access control, which allows only the internal network users and legitimate external users to access the public servers through the firewall, and the public servers cannot initiate access to the internal network, so that if the public servers are attacked, the internal network will remain secure and safe due to firewall protection. This way, if the public server is attacked, the internal network is still safe due to the protection of the firewall.
4. Encryption
At present, the types of VPN services carried out by network operators generally have the following three types:
1. dial-up VPN service (VPDN) 2. leased-line VPN service 3. MPLS VPN service
Mobile interconnection network VPN service should be able to provide users with dial-up VPN, leased-line VPN service, and should consider the support of MPLS VPN service. consider the support and realization of MPLS VPN service.
The 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 the realization of telecom-grade encrypted transmission with VPN-enabled routing equipment is the most feasible approach at this stage.
5, security assessment system
Network systems have security vulnerabilities (such as security configuration is not tight, etc.), operating system security holes, etc. is an important factor in the hackers and other invaders attack repeatedly. Moreover, with the upgrading of the network or the addition of new application services, the network may have new security vulnerabilities. Therefore, it is necessary to have a network security scanning system and system security scanning system to detect security holes in the network, and should be used frequently to analyze the scanning results of the audit, and take appropriate measures to fill the system vulnerabilities in a timely manner, the existence of network equipment and other insecure configuration to re-configure the security.
6, intrusion detection system
In the view of many people, with a firewall, the network is safe, you can rest easy. In fact, this is a wrong understanding, the firewall is the realization of network security is the most basic, the most economical, one of the most effective measures. Firewalls can strictly control all access (allow, prohibit, alarm). However, it is static, while network security is dynamic and holistic, there are countless methods of attack by hackers, firewalls are not omnipotent, and it is impossible to completely prevent these intentional or unintentional attacks.

Chapter I Preface < /p>
Today's automotive industry is characterized by a high level of security and safety.
Today's network operators are experiencing an exciting information explosion, with network backbone bandwidth doubling on average every six to nine months. Data services, the dominant service type, are demanding and driving fundamental changes in network architecture. The emergence of optical Internet has laid a new foundation for network applications based on IP technology. Along with the popularization of the network, the application of information network technology, the expansion of key business systems, the security of business systems in the telecommunications sector has become an important issue affecting the effectiveness of the network, and the openness, internationality and freedom that Internet has increased the degree of freedom of application at the same time, put forward higher requirements for security. Due to the changes in the international situation, the possibility of the outbreak of network war has been intensified, and safeguarding network and information security is directly related to the country's economic security and even national security. Therefore how to make the information network system from hackers and spies invasion, has become an important issue to consider the healthy development of the national telecommunications infrastructure network.
In the new telecommunication market environment, the diversification of demand and personalization of information consumption have gradually become an inevitable trend, which is especially evident in the field of data communication. After several years of efforts, the public data communication network has made a leap in scale and technical level, the number of users continues to grow at a high speed, and the development of information business users is particularly rapid, with the number of national large group users increasing and beginning to shift to enterprise users; *** Internet access project is progressing smoothly, e-commerce has been launched in full swing, and the security authentication system of China Telecom passed the joint appraisal held by China's Cryptography Management Committee and the Ministry of Information Industry. The Ministry of Information Industry held a joint appraisal of the security authentication system of China Telecom, and effective cooperation was carried out with the financial sector. Telecom also provides Internet access service, IP telephone service and other services. The IP bearer network carries a unified platform for image, voice and data, emphasizing Qos, VPN and billing, making it a multi-service bearer network in the new era. The development of China Telecom's data communication is located in network services to realize personalized services. In fact, this category of network functions are very rich, such as stored-value card business, e-commerce authentication platform, virtual private network and so on. And all of this depends on the guarantee of network security, if there is no security, personalized services can not be talked about at all. Only the basic level of telecommunication *** good, function strengthened, security issues are guaranteed, to be able to provide a truly personalized service.
Because of the special nature of the telecommunications sector, the transmission of important information, is the basis of the entire national communications system. Its security is particularly important. Due to some of our technology and foreign countries still have a certain gap, the domestic existing or under construction of the network, the use of network equipment and network security products are almost exclusively foreign manufacturers of products. Only the use of domestic self-developed information security products, security products with independent copyright, in order to truly grasp the initiative on the information battlefield, in order to fundamentally prevent malicious attacks and damage from a variety of illegal. Most of today's computer networks are security mechanisms established in the network layer security mechanisms, that network security is only firewalls, encryption machines and other equipment. With the expansion of the degree of interconnection of the network, the diversity of specific applications, this security mechanism for the network environment is very limited. In the face of various threats, it is necessary to take strong measures to ensure the security of computer networks. It is necessary to make an in-depth understanding of the network situation, make a rigorous analysis of the security requirements, and put forward a perfect security solution. This program is based on the specific network environment and specific applications of the telecommunications network, to introduce how to establish a complete set of network security solutions for the telecommunications sector.
Chapter 2: Network Security Overview
Definition of Network Security
What is computer network security, despite the fact that the term is now very hot, but not many people really have a correct understanding of it. In fact it is not easy to properly define computer network security, the difficulty lies in forming a definition that is sufficiently go comprehensive and effective. In common parlance, security is the avoidance of risk and danger. In computer science, security is the prevention of:
Unauthorized access to information by unauthorized users
Unauthorized attempts to destroy or alter information
This can be restated to mean that security is the ability of a system to protect the confidentiality and integrity of information and system resources accordingly. Note that the scope of the second definition includes system resources, i.e., CPUs, hard disks, programs, and other information.

Question 7: What are the special products for computer information system security Special products for computer information system security are: antivirus, firewall, active defense, data analysis, backup, focusing on the field of security protection of classified information. In terms of information protection, the product is more complete.
Specialized products for the basis:
1, "The Chinese People's **** and the State Computer Information System Security Protection Regulations" (February 18, 1994, issued by the State Council Decree No. 147).
2, "computer information system security special product testing and sales license management" (December 1, 1997, the Ministry of Public Security Decree No. 32)
3, "Computer Virus Prevention and Control Management Measures" (April 26, 2000, the Ministry of Public Security Decree No. 51)
Question 8: What are the product certifications? Electronic product certifications
Now the world, regardless of the industry, the use of electronic home appliances through a variety of security certifications (which, of course, does not include those "underground factories" production of products yo). Why do we need to have safety certification? This is also a commitment by manufacturers to the safety of their products, related to radiation, electrical safety, personal safety and so on.
Your monitor and your computer's power supply (POWER) is whether there is a lot of identification? If not, be careful, those products are not safe. In the face of all kinds of certification and its labeling, you understand what it means? Here is a brief introduction to some of the most common security certificates in the computer information industry, I hope to help you in the future hardware purchases will be helpful.
CCC certification
China's compulsory product certification in May 1, 2002 onwards, the name of the certification mark "China Compulsory Certification" (English China pulsory Certification abbreviation "CCC"). "). Included in the General Administration of Quality Supervision, Inspection and Quarantine and the Certification and Accreditation Administration of the State issued the "first implementation of mandatory product certification of the product catalog" in the implementation of mandatory testing and auditing of products.
Where included in the catalog of products not certified by the designated body, not in accordance with the provisions of the labeling of the certification mark, are not allowed to leave the factory, import, sale and use in the business service establishments. After the implementation of China's mandatory certification mark, will gradually replace the original implementation of the "Great Wall" logo and "CCIB" logo. The original "Great Wall" logo and "CCIB" logo since May 1, 2003 shall be abolished.
CCEE certification
CCEE certification mark - the Great Wall logo China Certification Commission for Electrical Equipment (CCEE) was established in 1984, the English name for the China mission for Conformity Certification of Electrical Equipment (hereinafter referred to as CCEE), is the representative of China's electrical equipment. CCEE), on behalf of China to participate in the International Electrotechnical Commission Electrical Product Safety Certification Organization (IECEE) of the only agency, is China's national certification organization in the field of electrical products, CCEE has four sub-committees under the electrical equipment, electronic products, household appliances, lighting equipment. Now abolished.
CCIB Certification
CCIB is the English acronym for China National Import and Export Commodity Inspection Bureau (China modity Inspection Bureau). Imported goods safety and quality licensing system is the State Import and Export Commodity Inspection Bureau (referred to as SACI) of imported goods to implement the safety certification system, where included in the SACI import safety and quality licensing system directory of commodities, must be through the product safety type test and factory production and testing conditions of the review, qualified, affixed with the CCIB safety mark of the commodity inspection, before being allowed to export to China, sales. Commonly used in authentic imported equipment, electrical appliances. Now abolished.
CE certification
The use of CE marking is now more and more, affixed with the CE marking of goods to indicate that it meets the safety, health, environmental protection and consumer protection and a series of European directives to express the requirements of the CE on behalf of the European unity (CONFORMITE EUROPEANNE). CE is only limited to the product does not jeopardize the safety of humans, animals and goods. The CE is limited to the basic safety requirements that the product does not jeopardize the safety of humans, animals and goods, and not to the general quality requirements, which are the mandate of the standard.
The product meets the main requirements of the relevant quality, it can be attached to the CE marking, but not according to the general quality of the standard provisions of the ruling on the use of CE marking. Therefore, the precise meaning is: CE marking is a mark of conformity for safety and not for quality.
CQC product quality certification
CQC agency name for the China Quality Certification Center, now China's mandatory certification CCC certification by its commitment. CQC product certification certificate, affixed with the CQC product certification mark, it means that the product is certified by the national certification body for safety, in line with the national response to the quality standards.
CSA certification
CSA is the Canadian Standards Association (Canadian Standards Association), which was founded in 1919, in the North American market for the sale of electronic, electrical and other products need to obtain safety certification. At present, CSA is Canada's largest security certification body, is also one of the world's most famous security certification body. It can provide safety certification for all types of products in the areas of machinery, building materials, electrical appliances, computer equipment, office equipment, environmental protection, medical fire safety, sports and recreation.
