2016年10月21日，Dyn Botnet Cyberattack收购了主要的在线零售商和互联网服务提供商。
最好设计可以对其固件进行现场更新的设备，以便针对未来无法预料的漏洞进行修补。
建议不要设计允许用户保持密码默认的设备，并且作为用户，最好不要在路由器和安全摄像头等设备上保留默认密码。
Microchip目前提供安全IoT传感器节点，该节点与板载CrytoAthentication芯片一起发布，该芯片经过编程，可与Google Core云服务一起开箱即用。
想让您的城市变得更聪明吗？
想要动态适应入住的架构吗？
您是否希望您的奶牛在办理登机手续时自动注册其RFID标签并控制他们对挤奶机器人的访问？
Microchip安全连接开发平台AVR-IOT WG，Microchip部件号AC164160的核心是AVR ATMEGA4808微控制器。
物联网连接由WINC1510 802.11 Wi-Fi模块提供，该模块将通信和网络从微控制器中解脱出来。
安全性由ATECC608A安全元素提供，预编程用于协商与Google Cloud的成功连接。
该板具有mikroBUS ClickBoard™占位面积，可利用MikroElektronika和第三方制造商提供的数百种传感器和扩展板。
0.1“间距插头突破还允许轻松访问SPI和I2C总线，并且该板提供高分辨率温度传感器和光传感器。
该主板配有四个状态LED，可轻松监控Wi-Fi连接，Google Cloud Connection，成功上传数据以及专用于错误状态的LED。
AVR-IOT WG板进一步有助于易用性，它作为大容量存储设备出现，连接到PC允许用户访问包含加密配置数据和序列号的快速入门指南和文本文件。
在开发过程中，用户只需将hex文件拖放到文件夹中即可对设备进行编程。

October 21st, 2016, the Dyn Botnet Cyberattack takes out major online retailers and internet service providers.

It's best to design devices whose firmware can be field updated to patch for future unforeseen vulnerabilities.
It's advisable to not design a device that allows users to keep passwords default, and as a user it's a good idea not keep default passwords on devices like routers and security cameras.
Microchip has available at this time a Secure IoT Sensor node, released with an onboard CrytoAthentication chip programmed to work out of the box with Google Core Cloud Services.
Want to make your city smarter? Want architecture that dynamically adapts to occupancy? Do you want your cows to automagically register their RFID tag upon check in and control their access to the milking robot?
The brains behind Microchip's secure connected development platform, AVR-IOT WG, Microchip Part Number AC164160 is an AVR ATMEGA4808 microcontroller.
The IoT connectivity is provided by the WINC1510 802.11 Wi-Fi module, which takes the communication and networking heavy lifting off the microcontroller.
The security is provided by the ATECC608A Secure Elements, preprogrammed to negotiate a successful connection to the Google Cloud.
The board has a mikroBUS ClickBoard™ footprint that leverages the hundreds of sensor and expansion boards available from MikroElektronika and third party manufacturers. The 0.1" pitch header breakout also allows for ease of access to the SPI and I2C buses, and the board comes supplied with a high-resolution temperature sensor and light sensor.
The board comes with four status LEDs that allow for ease of monitoring Wi-Fi Connectivity, the Google Cloud Connection, successful data uploads, and one dedicated to error status.
Further assisting in ease of use, the AVR-IOT WG board appears as a mass storage device, connecting to a PC allows the user to access the quick start guide and text files that contain the encryption configuration data and serial numbers. While developing, a user can just drag and drop a hex file into the folder to program the device.
