Question

Common causes which allow system exploits include (select all that apply)

a. Validating all function input
b. Failing to check for input length
c. Hard-cording credentials
d. Missing authorization

Answer 1

System exploits can occur due to several common causes: failing to validate all function input, not checking for input length, and hard-coding credentials.

Step-by-step explanation:

System exploits can occur due to several common causes:

1. Validating all function input: Failing to properly validate user input can lead to vulnerabilities that hackers can exploit. For example, if a website does not validate user input in a contact form, an attacker could inject malicious code.
2. Failing to check for input length: Ignoring input length checks can result in buffer overflow or denial-of-service attacks. For instance, if a website does not limit the length of a user's input, an attacker can flood the system with excessive data, causing it to crash.
3. Hard-coding credentials: Hard-coding sensitive information like usernames and passwords in the source code is a security risk. If an attacker gains access to the code, they can easily retrieve these credentials and breach the system.

These are just a few examples of common causes that can lead to system exploits. It is crucial to implement appropriate security measures to mitigate these risks.

Therefore, the correct option is a. Validating all function input.
