6. How should you store your application user credentials in your application

database?
bq
Use application logic to encrypt credentials
bq bq bq bq bq
Store credentials as clear text
bq bq bq bq bq
Store credentials using Base 64 encoded
bq bq bq bq bq
Store credentials using salted hashes: Store credentials using salted hashes
bq bq bq bq bq bq bq bq bq
Hashing is a one-way process that converts a password to ciphertext using hash
bq bq bq bq bq bq bq bq bq bq bq bq
algorithms. Password salting adds random characters before or after a password
bq bq bq bq bq bq bq bq bq bq bq
prior to hashing to obfuscate the actual password.

ments during the software assessment phase?
bq bq bq bq bq bq
Certification is required if the organization wants to move to the cloud. bq bq bq bq bq bq bq bq bq bq bq
Depending on the environment in which the product resides, certifications
bq bq bq bq bq bq bq bq bq bq
may be required by corporate or government entities before the software can
bq bq bq bq bq bq bq bq bq bq bq bq
be released to customers.
bq bq bq bq
By ensuring software products are certified,the organization is protected from

By ensuring all developers have security certifications before writing any
bq bq bq bq bq bq bq bq bq
code, teams can forego discovery sessions.: Depending on the environment in

which the product resides, certifications may be required by corporate or govern-
bq bq bq bq bq bq bq bq bq bq bq bq
ment entities before the software can be released to customers.
bq bq bq bq bq bq bq bq bq bq
Any new product may need to be certified based on the data it stores, the frameworks it
