Of course, you have to do some equipment certification, and you can't let other boxes access your network. Simply put, you only need to do the basic verification and authorization of a device, register an account, and the cloud management platform will run on its own.
This has solved many problems in the networking of chain enterprises. The biggest advantage of SD-WAN technology is its high security and good stability. For chain enterprises, it also saves a lot of high networking costs, which can be described as killing two birds with one stone.
The specific implementation method of SD-WAN solution is as follows:
First, a secure SD-WAN system.
(1) All data transmitted through SD-WAN tunnel are encrypted with 128- 168 bits of AES/3DES encryption algorithm, which can effectively prevent data from being eavesdropped or tampered with.
(2) Strict key authentication, only users who know the key can access it to prevent illegal users from breaking in. The key is kept by the company's network management and can be changed at any time.
(3)iNAS digital certificate technology supports PKI authentication system and binds computer hardware information (hard disk, CPU, network card, etc.). ) SD-WAN users. Only when the user name, key and user's digital certificate are fully authenticated can the connection be made. Even if the user name and password are stolen, the SD-WAN network is still unbreakable.
(4) Powerful intranet management function. After the branches connect to the headquarters LAN through SD-WAN, they can only access the intranet resources allocated by the headquarters administrator. Different branches can set different access rights to avoid malicious attacks using the intranet, thus effectively ensuring the security of the network.
Second, it is fast.
SD-WAN adopts kernel driver technology and LZO algorithm, which can make the bandwidth utilization rate as high as 90%, especially suitable for database, file transfer and other applications. During file transfer, the maximum compression ratio can reach 180%.
Thirdly, an efficient and stable SD-WAN system.
SD-WAN supports full-dynamic IP address networking, and also supports various access modes, such as ADSL/PSTN/IP/GPRS/WLAN. The stability of SD-WAN addressing truly realizes the proprietary intranet.
