HTTP Inspector
HTTP is one of the most prevalent protocols used over the internet. Recent statistics show that there are more than five billion internet users currently. There are more than 150 million .com
domains, which is the most of any top-level domains. The total number of websites exceeds 2 billion; there were 300 million online shoppers in the US in 2023. Web traffic is at the core of the internet, and HTTP still plays a key role. Subsequently, a significant percentage of attacks and breaches occur via HTTP. According to the 2023 Data Breach Investigations Report conducted by Verizon, 26% of breaches occurred via HTTP. In order to successfully detect malicious behavior and attacks over HTTP, the Snort system will have to decode the protocol and enable the identification of malicious and/or suspicious artifacts. The HTTP Inspector module performs the decoding and analysis of HTTP to enable such detection.
