Smart device refers to any device, device or machine with computing processing capabilities. So how much do you know about smart devices? The following is what I have compiled about what smart devices are. I hope you like it!

The core of smart devices

Smart devices are traditional electrical devices A product that combines computer technology, data processing technology, control theory, sensor technology, network communication technology, power electronics technology, etc.

Smart devices mainly include two key aspects: self-detection is the basis of smart devices; self-diagnosis is the core of smart devices.

Intelligent equipment is a highly automated electromechanical equipment. Due to its complex structure, it plays a very important role in the system, so it has high requirements for the reliability of intelligent equipment. The reliability of components, technical design, process level and technical management all determine the reliability indicators of electronic products. To improve the reliability of products, we must master the failure patterns of products. Only by comprehensively understanding the failure patterns of products can we take effective measures to improve product reliability.

Categories of smart devices

As computer technology becomes more and more advanced and cheaper, various types of devices can be built, including personal computers and handheld computers. There are many smart devices, including medical equipment, geological equipment, household equipment, etc.

Characteristics of smart devices

The intelligence of smart device application platforms is reflected in the fact that the system composed of heterogeneous devices has the characteristics of situation awareness, task migration, intelligent collaboration and multi-channel interaction. .

Context-aware applications capture, analyze, and respond to relationships between multiple objects. Device collaboration refers to coordinating the services provided by different devices, integrating the functions of existing available services, and constructing new combined services with richer functions. Multi-channel interaction refers to a human-computer interaction method that uses multiple channels to communicate with computers, where "channel" refers to the communication method for users to express intentions, perform actions, or perceive feedback information.

Security goals of smart devices

U- Ubiquitous ubiquitous network, security ubiquitous

The development trend of the Internet of Things is to connect everything that is not yet connected, including daily Equipment closely related to life? Cars, refrigerators, washing machines, electricity meters, health equipment, etc. Faced with the ubiquity of this kind of networking, the protection provided by Bangbang Security can be oriented to every networked endpoint/intelligent device, strengthening the endpoint's ability to resist attacks, and realizing ubiquitous security protection.

S-Security comprehensive end-pipe-cloud security protection

Bangbang Security end-pipe cloud security protection architecture protects against new access devices, new applications, and new scenarios in the Internet of Things , new technology applications and other security risks introduced at all levels:

End: based on chip-level protection solutions, white box protection, source code protection, strong authentication mechanism, multiple verification, etc.

Management: communication protocol protection, communication authorization authentication, traffic security filtering, etc.

Cloud: mobile application security/behavioral firewall, secure storage, endpoint threat awareness, risk big data analysis, etc.

C- Cloud provides security protection in the form of cloud services

Faced with the characteristics of the Internet of Things connecting millions or tens of millions of smart devices, Bangbang Security adopts cloud architecture to Cloud service approach to achieve security protection and management:

Security protection: white box password service, source code protection, vulnerability detection, security evaluation, channel monitoring.

Management and response: endpoint threat awareness, traffic behavior audit, risk statistical analysis, OTA upgrade.

The Internet of Things reminds everyone of a scenario where everything is interconnected. The security of such a large and complex network requires systematic solutions.

For example, for the security protection of smart devices, in Bangbang Security's USC architecture, it is more of a "port" security protection. In addition to smart devices, Bangbang Security also considers the mobile APP that controls smart devices. security; the communication between smart devices and the cloud belongs to the protection of the "management". The intrusion into the wireless network to control the washing machine and oven demonstrated at the 315 party is an attack on communication; when the smart device is controlled, the "cloud" in the USC architecture Services can provide another line of security defense through threat awareness or behavioral auditing.

Smart device security is a very important link in the security of the Internet of Things. It is precisely for this reason that Bangbang Security Research Institute first proposed the concept of "micro-boundary" for Internet of Things security and proposed basic security Protection principles:

1. Security needs to be ubiquitous at every micro-border point, so that every micro-point has security protection and anti-attack capabilities.

2. Security deployment and operation and maintenance must be able to adapt to a large number of diverse and diversified sensing devices.

3. Security threat discovery, monitoring and response must be fine-grained to each micro-boundary point.
