    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.
