Some common types of hardening procedures include software updates,
also called patches, and device application configuration changes.
These updates and changes are done to increase security and
fix security vulnerabilities on a network.
An example of a security configuration change would be requiring longer
passwords or more frequent password changes.
This makes it harder for a malicious actor to gain login credentials.
An example of a configuration check is updating the encryption standards for
data that is stored in a database.
Keeping encryption up to date makes it harder for
malicious actors to access the database.
