Special risks associated with computer information systems

Answer]: a, b, c, d

The main risks affecting the security of computer systems are: system failure risk, internal personnel moral hazard, system related party moral hazard, computer virus and social moral hazard.

1. Be vigilant:

When the overall ** shows a large increase, the trading volume.

When the number of people who have repeatedly created a large number of days, the popularity of the money-making effect in the market, the market sentiment is boiling, investors are enthusiastic to enter the market, and the risk awareness of shareholders is gradually indifferent, it is often a sign that systemic risk will appear. From the analysis of investment value, when the overall value of the market has a tendency to be overestimated, investors must not relax their vigilance against the systemic risk of the system.

2. Proportion of investment:

In the process of operation, there are always uncertainties, and investors can constantly adjust the proportion of capital investment according to the stage of development. Due to the large increase in **, from the perspective of effective risk control, investors should not adopt the method of heavy position operation, as for the full position operation of all in and all out, it is more inappropriate to add a high position.

During this period, it is necessary to control the proportion of capital investment within the range of tolerable risks. Heavier investors can selectively throw some, lighten it, or use some of their investment funds for relatively safe investments, such as subscribing for new shares.

Wait. 3. Preparation for winning and losing:

Investors can't afford to experience systemic risk when, especially during periods of rapid rise. If you sell your ** in advance, it often means that investors cannot enjoy the "crazy"** pull up opportunity. At this time, investors can continue to hold shares under the premise of control, but at any time ready to take profit or stop loss, once the market appears system situation risk, investors can decisively cut positions to sell, so as to prevent further expansion of losses.

There are several behaviors that endanger the security of the computer information system of the sedan car:

1) Illegal intrusion into computer systems, i.e., intrusion into computer information systems in the fields of national affairs, national defense construction, and cutting-edge science and technology;

2) Illegal destruction of computer systems, i.e., deliberately making and disseminating destructive programs such as computer viruses to attack computer systems and communication networks, causing damage to computer systems and communication networks;

3) Illegal interruption of network services, that is, the interruption of computer networks or communication services in violation of national regulations, resulting in the failure of the normal operation of the computer network or communication system of the computing office.

Penalties: The public security organs shall give a warning or impose a fine of less than 5,000 yuan on individuals and a fine of less than 150,000 yuan on units; Where there are unlawful gains, in addition to confiscation, a fine of 1 to 3 times the amount of the unlawful gains may be imposed.

According to Article 24 of the "Regulations of the People's Republic of China on the Security Protection of Computer Information Systems": Violations of the provisions of these Regulations, constituting a violation of the administration of public security, shall be punished in accordance with the relevant provisions of the "Law of the People's Republic of China on Public Security Administration Punishments"; where a crime is constituted, criminal responsibility is pursued in accordance with law.

There are many factors that affect the security of computer networks, and the threats to network security mainly come from three factors: unintentional human mistakes, malicious attacks by man, and vulnerabilities and "backdoors" of network software systems.

Software vulnerabilities: Every operating system or network software cannot be flawless and Zheng Lu vulnerabilities. This puts our computers in a dangerous position and becomes a target once they are connected to the network.

Lack of security awareness: Careless password selection, or lending or sharing your account with others will pose a threat to network security.

Improper configuration: Improper security configuration causes security vulnerabilities.

Physical security: The entity of a computer system is the hardware part of a computer system, which should include the hardware and various interfaces of the computer itself, various corresponding external devices, communication equipment, lines and channels of the computer network. Operational security:

Operational security is an important part of the security of the computer information system, and only when the security of the computer information system is guaranteed in the process of operation can the correct processing of information be completed and the purpose of giving full play to the functions of the system can be achieved. <

Demo model: Huawei MateBook X System version: Win10 1, Physical security:

A computer system entity refers to the hardware part of a computer system, which should include the hardware and various interfaces of the computer itself, various corresponding external devices, communication equipment, lines and channels of the computer network.

2. Operational security: The operational security of the system is an important part of the security of the computer information system, because only the security of the operation of the computer information system is guaranteed, in order to complete the correct processing of information and achieve the purpose of giving full play to the functions of the system.

3. Information security: The information security of the computer information system is the core, which refers to preventing the information property from being deliberately or accidentally leaked, altered, destroyed or the information being identified and controlled by the illegal system, and ensuring the confidentiality, integrity, availability and controllability of the information.

4. Security management: safety management includes improving security awareness, effectively ensuring the security of information systems, as well as improving the technical level and enhancing the technical prevention capabilities of information systems.

1. Network attacks and attack detection and prevention;

2. Security vulnerabilities and security countermeasures;

3. Information security and confidentiality;

4. Internal security precautions of the system;

5. Anti-virus problems;

6. Data backup and recovery issues, disaster recovery issues.

Security threats. Information Disclosure, Breach of Information Integrity, Denial of Service, Illegal Use (Unauthorized Access), Eavesdropping, Business Flow Analysis, Impersonation, Bypass Control, Authorization Infringement, Trojan Horse, Trap Door, Repudiation, Replay, Computer Virus, Accidental Personnel, Abandonment, Physical Intrusion, Theft, Business Deception.

(i) Database risk: It is the core of the risk management information system and is the memory bank that stores basic information. Important activities for the establishment of the database are:

1.Choose the types of data that need to be included and the amount of data that should be collected for each data category, and the number and quantity of these data categories will depend on whether the economic unit deems it able to satisfy a feasible decision.

2.Determines the format and type of data, and the ability to make direct calls to perform the expected functions of the RMIS.

3.Modify and periodically check actual data.

2) Software risk: Risk managers need to consider the following issues when purchasing the pre-programmed RMIS software or hiring other software companies to compile or economic units to compile their own RMIS software:

1.Viability;

2.User-friendly interface;

3.Flexibility;

4.Comprehensive;

5.fault tolerance;

6.Compatibility;

7.analytical skills;

8.Security;

iii) Hardware Risks.

iv) Personnel risk: People are the most important in risk management information systems, providing and interpreting data, and designing, building, arranging and repairing hardware.
