How DDoS protects IoT security
To solve a problem, first of all, to define the concept of the object that needs to be solved? It is generally defined that the Internet of Things is the Internet connected to objects. It contains two meanings: First, the core and foundation of the Internet of Things is still the Internet, which is an extended and extended network based on the Internet; Second, its client extends and extends between any item and item. A sensing device and a camera are mounted on the object for information exchange and communication, that is, objects and objects. According to authoritative research institutions, by 2025, there will be 100 billion connections worldwide, and 6.5 billion Internet users will use 8 billion smartphones. By 2020, the global Internet of Things market will exceed $100 billion.
In the face of huge market demand for the development opportunities and development space of the Internet of Things, some security issues have surfaced, more and more physical devices are connected to the Internet of Things, and users’ security awareness is not enough. The physical devices are hijacked into zombies, and these devices are manipulated to launch DDoS attacks. Large-scale malicious traffic is blocked at the access portal, making normal access requests unreachable. So what do equipment manufacturers and IDC operators need to do to deal with such DDoS attacks?
First, equipment manufacturers need to add secure program settings to the terminal. The main reason why hackers can easily hijack a large number of physical devices is that these smart devices lack extensive security access control, just like rice cookers in smart homes. The refrigerator, although it is possible to carry out remote intelligent control, but who is controlling this person, and what kind of operation is allowed requires the manufacturer to think.
Secondly, IDC operators need to accurately judge and intercept in time when hackers hijack IoT devices to launch DDoS attacks. This depends on the firewall technology, creating a barrier between the attacker's IP and the server. For the service request initiated by the zombie, the firewall will use the relevant rules to identify, provide attack defense, intranet security, traffic monitoring, mail filtering, webpages. Measures such as filtering and application layer filtering protect website and data security.
Finally, individuals should always pay attention to changing the password of the physical device.
The Internet of Things connects inanimate objects and allows any device to join anywhere and connect all devices together and show different "life" signs. However, at the same time, if the security risks of "things" are long-term laissez-faire, the road to "Internet of Everything" will not be so flat.
