A computer-implemented method mitigates side channel attacks in cache memory. The method includes: loading data into a cache line of the cache memory, which includes marking the data as sensitive in metadata of the cache line based on the data being tagged as sensitive; tracking interactions with the data; and determining whether the interactions with the data are not normal based on a preset criteria and the tracked interactions with the data.
