The commonly used regularization techniques are : Lasso Regularization – L1 Regularization. Ridge Regularization – L2 Regularization.

A model that overfits a dataset, and achieves 60% accuracy on the training set, with only 40% on the validation and test sets is overfitting a part of the data. However, it's not truly overfitting in the sense of eclipsing the entire dataset, and achieving a near 100% (false) accuracy rate, while its validation and test sets sit low at, say, ~40%.
