Based on this research, Wei Ran Lab has conducted big data analysis, trained millions of samples, and selected the Random Forest algorithm to identify threats in encrypted communication traffic.

However, it's not a bad idea to normalize the predictors just in case you want to send the data to other regression algorithms that require normalization (for example, k-nearest neighbor regression).
