My InfoTech Journal will record the research that I have consolidated so that I can go back and use these articles for future reference.

I will start with topics related to Information Security, Data Privacy, and expand to other domains with the objective of promoting knowledge sharing for those that may have the same research requirement.

I will also share personal experiences that may be useful to the topics being presented.

I hope that these research articles will be useful to others looking for references on the same topic.
