Micro-Learning Topic: Insecure authentication (Detected by phrase)

Matched on "Improper Authentication"

What is this? (2min video)

Improper authentication happens when mechanisms intended to identify the user are flawed (easily tamperable or insufficient). This would allow an attacker to bypass access controls or to easily impersonate a user.

Micro-Learning Topic: Integer overflow (Detected by phrase)

Matched on "Integer Overflow"

What is this? (2min video)

Integer overflow occurs when the result of arithmetic operation is greater than the maximum value the integer data type can store.
For example, if an integer data type allows integers up to two bytes or 16 bits in length (or an unsigned number up to decimal 65,535), and two integers are to be added together that will exceed the value of 65,535, the result will be integer overflow.
