Embodiment Construction
[0052] The specific implementation of the present invention will be further described below in conjunction with accompanying drawings and examples, but the implementation and protection of the present invention are not limited thereto. Achieved with technology.
[0053] A security protection method for a smart home security gateway in this example is mainly composed of four steps, the steps are as follows:
[0054] Step 1: Power on the smart home gateway, start the dual network card according to the configuration file, and establish a secure connection with the server;
[0055] Step 2: The gateway obtains the legal user list from the server and caches it. The specific process is as follows figure 1 shown;
[0056] Step 3: Start the snort-wireless wireless network attack detection function according to the configuration;
[0057] Step 4: Start the smart home protocol attack detection system. Specifically include:
[0058] a) Extract the attack features of the smart home pr...

The invention discloses a safety protection method for a smart home safety gateway. The present invention solves the problem of insecure smart home routing by using dual network card adaptation technology and wireless network attack detection; improves the intrusion detection system to add intrusion detection and defense against smart home protocol attacks; implements access control for files and processes, and uses integrity metrics , Remotely prove the security of the monitoring gateway and form a virus protection system; dual network card traffic analysis provides detection and defense of Mirai virus and its variants. The present invention can not only ensure the devices that communicate with the smart home protocol in the intranet, but also ensure the communication security of other devices connected to the hotspot of the security gateway, resist attacks against the smart home protocol, provide virus detection and defense, and protect Mirai The botnet formed by the virus conducts effective detection and prevention, protects the network security of the dual network planes of the home and internal networks, and provides solutions and ideas for the security of smart homes and even the security of the Internet of Things.
Description
technical field [0001] The invention relates to the field of smart home security research, in particular to a security protection method for a smart home security gateway. Background technique [0002] Since 2016, the attack trend of smart home is Mirai (Mirai Malware, Mirai malware) virus, and it is continuously mutating. The attack method is to infect smart devices with malicious programs, thereby controlling smart devices to launch Distributed Denial of Service (DDOS) attacks on normal server nodes, generating Tbytes-level attack traffic and paralyzing the network. [0003] At present, there are many kinds of smart devices, lack of unified standards and specifications, coupled with limited resources, and special and refined security requirements. However, if a security solution is tailored for each type of device, the cost of the security function may be higher than the cost of the practical function itself, so existing manufacturers generally ignore security issues. Th...
