What are the main aspects of cybersecurity?

1. System security.

System security refers to the application of system security engineering during the life cycle of a system.

and system security management methods.

Identify hidden dangers in the system and take effective control measures to minimize the danger so that the system can achieve the best level of safety within the specified performance, time and cost range.

The security of business systems and operating systems is the premise of ensuring business security. In addition to paying attention to the function of the information system, we should also pay attention to the security of the system application. It is not only necessary to use strong passwords to protect the information system, but also to regularly check and upgrade the system to strengthen the two-way protection of the system internally and externally.

There are many factors involved in whether a system is safe or not, including the security awareness of the system developer, operator errors, and regular inspections of the system.

2. Application security.

Application security is about securing applications.

Safety of use process and results. In other words, other security tools or policies are used to eliminate the potential leakage and theft of computing and transmission data during the use of applications or tools.

Applications and systems are inseparable, and applications involve more personal information and important data, whether it is a web application or a mobile application.

Detection work. 3. Physical Security.

In network security, physical security is also a very important part, in addition to the purchase and deployment of equipment, we should also consider whether it is properly stored, whether it is operated and maintained, and whether it is operated properly. Environmental accidents occur from time to time, as for natural disasters.

We can't anticipate it, but we can avoid it. In addition, network equipment.

should be checked and upgraded regularly, and network equipment will also have security risks.

Whether the policy is updated and the environment of the data center should be considered as security issues.

Fourth, management security.

Management is the most important part of security in a network. The division of labor and responsibilities are not clear, and the safety management system is not clear.

Unsound and so on may lead to risks in management security.

When the network is attacked or other security threats are encountered, real-time detection, monitoring, and alarm cannot be performed. At the same time, when an accident occurs, it is impossible to trace the cause, which requires us to record the access activities of the site at multiple levels and detect illegal intrusion in time.

Network security means that the hardware, software and data in the network system are protected from damage, alteration and leakage due to accidental or malicious reasons, and the system runs continuously, reliably and normally, and the network service is not interrupted.

Cybersecurity, by its very nature, is information security on the network. Broadly speaking, all related technologies and theories related to the confidentiality, integrity, availability, authenticity and controllability of information on the network are the research fields of network security. Cyber security is a comprehensive discipline involving computer science, network technology, communication technology, cryptography technology, information security technology, applied mathematics, number theory, information theory and other disciplines.

It is recommended to introduce micro-isolation techniques. With the application of multi-cloud environment and container technology, the data center infrastructure is constantly changing, coupled with the abundance of attack methods and the improvement of technology, 0-day vulnerabilities, no-kill technology, phishing emails, etc. are frequent visitors in the drill. Micro-isolation is mainly used for the visual identification and access control technology of east-west traffic (intranet security) in the data center, as a company that only focuses on the exploration and research of micro-isolation technology in China, Rose Smart has a deep technical foundation and rich experience in the industry customer in this technical field, and has been working for CNOOC, PetroChina, China Life Insurance, Shenhua, TravelSky and other financial and government affairs

Network security includes computer software and hardware security, network system security, and he mainly has the following aspects:

First, the first maintainer.

Due to some well-known people, the daily workload and data information are very large, so there will definitely be various problems in the normal operation state, such as some data loss and even crashes, at this time we need a first-class maintenance personnel, and we can use the learning content through network security training in our work.

2. Network security engineer.

In order to prevent hackers from hacking and stealing confidential company information and protecting users' information, many companies need to build their own network security work, and network security engineers are the core personnel who are directly responsible for protecting the company's network security.

3. Penetration testing positions.

The penetration testing position is mainly to simulate hacker attacks, use hacking techniques, dig out vulnerabilities, and propose fixes. It requires the use of databases, network technologies, programming techniques, operating systems, infiltration techniques, attack and defense technologies, reverse technologies, etc.

Fourth, classified protection assessment.

The security assessment is mainly for the security level assessment of the target information system, which requires the use of databases, network technologies, operating systems, infiltration technologies, attack and defense technologies, and so on.

5. Offensive and defensive engineers.

The position of offensive and defensive engineer is mainly required to be able to penetrate and prevent, and it is necessary to use technical points such as database, network technology, operating system, programming technology, and penetration technology.

Network security should include: enterprise security system, data security, transmission security, server security, firewall security (hardware or software implementation, back-to-back, DMZ, etc.), anti-virus security.

Different types of cybersecurity arise due to different environments and applications. The main ones are as follows:

1. System security.

The security of the operation system is to ensure the security of the information processing and transmission system. It focuses on keeping the system up and running. Avoid damage and loss of information stored, processed, and transmitted by the system due to system damage.

Avoid information leakage, interference with others or interference by others due to electromagnetic leakage.

2. Network security.

Security of system information on the network. Including user password authentication, user access authority control, data access authority and method control, security audit, computer virus prevention, data encryption, etc.

3. Information dissemination security.

The security of information dissemination on the network refers to the security of the consequences of information dissemination, including information filtering. It focuses on preventing and controlling the consequences of the dissemination of illegal and harmful information, and avoids the loss of control of information freely transmitted by the big cloud on the public network.

The main content of cybersecurity:

1. The operating system does not have relevant security configurations.

No matter what kind of operating system is used, there will be some security problems in the case of incomplete installation, and only relevant and strict security configuration for the security of the operating system can achieve a certain degree of security. Don't think that after the operating system is installed by default, as long as the password you set is strong, there is no problem. Vulnerabilities and "backdoors" in cyber software are the preferred targets for cyberattacks.

2. No CGI program audit was conducted.

If it is a general CGI problem, it is slightly easier to prevent, but for some CGI programs specially developed by ** or software vendors, many of them have serious CGI problems, and for e-commerce sites, there will be serious consequences such as malicious attackers fraudulently using other people's accounts for online shopping.

3. Denial of Service (DOS) attacks.

Nowadays, the requirements for real-time performance are getting higher and higher, and the threat of DOS or DDoS is getting bigger and bigger. If a cyber attack is aimed at cyber paralysis, then its attack effect is very strong, the damage is very large, the speed and scope of the damage are also unpredictable, and the risk of the attacker itself is very small, and it can disappear without a trace even before the attack starts.

4. Improper use of safety products.

While many ** have adopted basic network security devices, these products have not worked as well as they should due to problems with the security products themselves or usage issues. Even if the manufacturer initially makes the correct installation and configuration for the user, once the system is changed and the settings of the relevant security products need to be changed, it is easy to cause many security problems.

5. Lack of strict network security management system.

The most important thing in network security is to have a corresponding system to guarantee, and the establishment and implementation of a strict computer network security system and strategy is the basis for truly realizing network security.
