Network Security Sensors

There are many network security devices and tools to help defend against computer networks, but these tools become increasingly complex and rely on preventing confidential and destructive attacks. This will analyze the features and benefits of various intrusion detection / defense systems (IDPS) and other network traffic monitoring tools to protect high value targets from advanced persistent threats. Current generation security devices are extremely difficult to provide absolute protection against these threats and are particularly important for new types of targeted attacks.

A few years ago, in Love Hz inspired by Japan's safe cast radiation monitoring network, I created the term "guerilla sensor network". People can organize their own sensor devices (flood sensors, temperature sensors, air quality sensors, bicycles, position tracking systems, etc.) top-down as part of the grassroots development rather than management. Telecom company approach I have already considered the TV blank on the Internet, but already mature ISM band is a good choice to achieve this goal.

A wireless sensor network is a wireless network of spatially distributed autonomous devices that uses sensors to measure physical or environmental quantities such as temperature, sound, vibration, pressure, and movement in various locations. The main purpose of a wireless sensor network is to collect information from the target domain and pass it to a specific task. Such a network usually consists of a number of wireless sensor nodes arranged in a simple way, each node being connected to a network of energy sources, which consists of one or more sensors, a low power transceiver, a processor, and possibly a battery Become. Since the sensor node's radio consumes a lot of energy, the lifetime of the network is shortened. In order to reduce the energy consumption of these sensor nodes, the design of low power electronic devices has been studied. Due to hardware limitations, further energy efficiency can be achieved by designing an energy efficient communication protocol.

Mono's Internet (IoT) is a network of physical objects such as devices, vehicles, buildings, etc. that incorporate electronic equipment, software, sensors, and network connections that enable the collection and exchange of data. It has been developed without fully considering security problems. The Internet 's Internet creates opportunities for the physical world to integrate directly with computer - based systems, but it also provides opportunities for misuse. Especially since the Internet's Internet is widely used, cyber attacks can become a more physical (non-virtual) threat. If the front door lock is connected to the Internet and can be locked / unlocked by phone, the criminal can enter the home by pressing the button of the stolen or hacked phone. In the world where devices supporting IoT are mainstream, people may lose something more than the credit card number.
