Study Notes
Program Flaws
- As programs become more numerous and complex, users are often unaware of what the program is doing or whether it's producing correct results.
- Users may not know if a program is flawed, even if it stops abruptly, loses data, or skips passages.
- Program flaws can have security implications, affecting the correctness of the program's results and leading to integrity failures.
Security Implications of Program Flaws
- A program flaw can lead to incorrect operation, affecting integrity, which involves correctness, accuracy, precision, and consistency.
- Faulty programs can modify or overwrite correct data, leading to serious harm.
- Even non-malicious flaws can be exploited by attackers to manipulate the program's behavior, becoming part of a malicious attack.
Nonmalicious Program Errors
- Nonmalicious program errors include buffer overflows, incomplete mediation, and time-of-check to time-of-use errors.
Buffer Overflow
- A buffer overflow occurs when a program tries to store more data than the buffer can hold, causing excess data to "spill out" and potentially cause harm.
