The invention is a method for securing a system including a plurality of entities and a repository storing usage patterns. The method comprises the following steps: for each of the entities involved in a transaction requested by a user, capturing a behavior data reflecting the dynamic behavior of said entity, generating a set of locality-sensitive-hashing hashes from each of said behavior data, computing a similarity score for each of the entities involved in the transaction, based on both said usage patterns and the set of generated locality-sensitive-hashing hashes, and based on a subset of the computed similarity scores, applying a preset security action to the transaction.
