Network security company, also known as network information security company and network security company, is a new type of company. Many friends don't know what network security companies do. Let me give you a brief introduction.
The so-called network security company, its main business scope is network security business, including the overall solution of network security, the development and sales of network security equipment, providing network security maintenance services for enterprises and so on.
Second, what are the development directions of network security companies?
With the country's emphasis on network security, there are more and more network security companies in the market, and there are many development directions of network security companies, which are mainly broken down as follows:
1, cloud security
Cloud security is the embodiment of the new era of network information security. It integrates the concepts of grid computing, parallel processing and unknown virus. By monitoring the abnormal behavior of a large number of clients, it obtains information such as Trojan virus and malicious programs, transmits them to the server for analysis and processing, and then distributes the solutions to various clients.
2. Application security
Application security refers to the security of programs in the process and results, including web applications and software applications, mainly aiming at the security of data transmission during the use of programs and tools.
3. Business safety
Business security is mainly to protect business systems from security threats. Generalized business security includes: software and hardware platforms (operating system, database, etc.). ), the security of the business system itself (software or equipment) and the services provided. Narrow business security includes: the security of software and services owned by business systems.
4. Internet of Things security
The security of the Internet of Things is related to everything in our lives, such as door locks, home appliances, cars and so on. The security contents involved include: wireless sensor network security, key management, secure routing, secure location, radio frequency identification, privacy security, intrusion detection, authentication, secure data and so on.
5. Data security
For example, our mobile phone information, shopping information, identity information and so on. , all related to the websites, software, wifi and other clients we registered with identity information. Data security has two meanings: the data itself is safe, using modern cryptographic algorithms to protect data and strengthen identity authentication; Data protection and security, such as data backup, remote location, disk display and other means to ensure data security.
6. Industrial control system /OT safety
Industrial control system refers to the industrial control system controlled by industrial automation, which is mainly realized by the combination of machinery, electronics, electricity and software. The safety content of industrial control system mainly includes: industrial control system safety, industrial control safety technology, industrial control safety products, industrial control safety events, etc.
7. Network border security
Connecting networks with different security levels creates a network boundary. In order to prevent intrusion from outside the network, it is necessary to establish reliable security defense measures at the network boundary. Such as: government intranet and extranet, bank data network and Internet.
8. Endpoint security
We have heard of pc and mobile phone. The so-called endpoint security is the endpoint security of the network connection of these mobile phones, tablets, notebooks, computers and so on that we often use.
9, safety management and service
Network security is inseparable from people. To do a good job in network security, in addition to improving personal safety awareness, network security equipment operators should not only improve management system and safety professional level, but also know the correct specification and confidentiality of operation. Related services include operation and maintenance services and training services.
