1. A method, comprising:
reading, at a system, first content from a first storage component and second content from a second storage component, the first storage component to store a first set of information that is to remain unmodified during operation of the system, and the second storage component to store a second set of information that is to remain unmodified during operation of the system;
generating, using a hash function, a first hash value from the first content read from the first storage component and from the second content read from the second storage component;
comparing the first hash value with a second hash value that is generated using the hash function before generation of the first hash value, wherein the second hash value is generated from the first set of information and the second set of information, based at least in part on reading the first set of information from the first storage component and on reading the second set of information from the second storage component; and
determining a modification status of the first set of information and the second set of information based on comparing the first hash value with the second hash value.
