Title: **Alan David Boulanger: Innovator in Computer Network Security**

Introduction

Alan David Boulanger is a notable inventor based in Amherst, MA, with a strong focus on innovations in computer network security. He has been awarded a total of five patents, which showcase his expertise in detecting and responding to various kinds of malicious computer network activities. His contributions have made significant strides in the cybersecurity field, making networks more secure and efficient.

Latest Patents

One of Boulanger's latest patents involves a system for automatically detecting distributed port scans in computer networks. This detection and response system includes a set of algorithms crafted to discern TCP or UDP packets within streams of normal computer traffic. It focuses specifically on packets with a single IP Source Address (SA) and one or several Destination Address (DA) values, where the number of distinct Destination Port (DP) values exceeds a predetermined threshold. The system employs a lookup mechanism that records and traces packets based on their SA, DA, and observed DP values, allowing for timely reporting of suspicious activity.

In another innovative patent, Boulanger designed a system to automatically detect malicious computer network reconnaissance by updating state codes in a histogram. This detection system generates an alert upon the detection of unauthorized scanning within a network. By utilizing a lookup table to track the sequence of noted packets—SYN, SYN/ACK, and RST—this system employs algorithms to adjust state values. Once these values indicate that all three packet types have been observed, the system triggers an alert, thereby enhancing the network's defensive posture.
