When I was preparing for CISSP 3 years back, a line from the book AIO guide - Shon Harris really made an impact on me. It goes like this “ There are only two people in the world I trust - You and I and I m not so sure about you.” This statement summaries the entire zero trust model, I presume.

The application security is managed at the applistructure layer while the data sec

The Blog turns 3 !!!

Well, time flies and that is absolutely correct. One more year has gone by and the blog has turned 3 now. This year has been full of ups and downs, even from the blog perspective. I have been quite busy and hence the number of posts has been less. New initiatives are also in progress.  However, one aspect that has been just going up is the love and respect from the readers.
