You are assessing application or service availability with a port scan. All services use default ports.
This is an example of what type of exploit analysis?
In deterministic analysis, all data used for analysis is known beforehand. An example of this type of analysis is port scanning because we clearly understand the rules of the TCP three-way handshake beforehand and we know the default port numbers.
In probabilistic analysis don’t have all data beforehand and works on probabilities. Predictive analysis is not a term that is used when describing exploit analysis. Intuitive is also not a term used when describing exploit analysis.
