Software Composition Analysis (SCA) is a way of checking software code for potential security problems. It looks for "bad" pieces of code that could be used to do something harmful, like breaking into a computer or stealing personal data. SCA also looks for “good” pieces of code that can be used to patch up problems or add new features. It’s like a way of keeping track of all the parts of the code and making sure that the code is working properly and stays secure.
