CompTIA: Advanced Security Practitioner (CASP) Exam Prep

Answer: D - Using all lowercase letters does not improve the security of a password

Key Takeaway: Anything that will make a password more complex is beneficial to making that password more secure. All lower case or all upper case letters increases the vulnerability of the password to a brute force attack. A good password is of longer length, includes numbers, spaces and special characters, and varies the case of the letters.
