Packet Protector is an Arduino Embedded device that runs an IDS program that monitors the incoming network traffic on the Ethernet interface. The program implements a variety of protocols and mechanisms to analyze the traffic and detect potential threats.

One of the primary protocols used by the IDS program is the TCP/IP protocol suite. This protocol suite is commonly used in modern computer networks and provides a standardized way for devices to communicate with each other. The IDS program uses the TCP/IP protocol to analyze the packets of data that are transmitted over the network. The program examines the packet headers and payloads to determine whether they contain any suspicious content or behavior.

Another protocol used by the IDS program is the User Datagram Protocol (UDP). UDP is a connectionless protocol that is often used for streaming media and other real-time applications. The IDS program uses UDP to detect potential threats that may be present in this type of traffic.

The IDS program also uses various mechanisms to analyze the network traffic and detect potential threats. One of these mechanisms is signature-based detection. This technique involves comparing the characteristics of the network traffic against a database of known signatures of known threats. If the IDS program detects a match between the traffic and a known signature, it alerts the user and blocks the Ethernet output.

Another mechanism used by the IDS program is anomaly detection. This technique involves analyzing the network traffic for unusual patterns or behavior. The IDS program uses machine learning algorithms to detect anomalies in the traffic and identify potential threats. The machine learning algorithms are trained on a dataset of known threats and non-threats, allowing them to adapt to new and evolving threats.

The IDS program also uses a variety of blocking mechanisms to prevent potential threats from affecting the device or network. One of these mechanisms is the blacklisting of specific IP addresses or network ranges. The IDS program can be configured to block traffic from these addresses or ranges, preventing any potential threats from reaching the device.

Additionally, the IDS program can whitelist known safe traffic to prevent false positives and ensure that legitimate traffic is not blocked. The program can also block traffic based on specific protocols or ports to prevent known vulnerabilities from being exploited.

With the ever increasing global threat of cyber warfare and government surveillance, this device puts the internet user in control of the informational transactions which are occurring behind the scenes.
