1) Using course resources and the Internet, please explain a buffer overflow. Hi Class, Happy week 4 and post-Thanksgiving catch-up time. This week we are discussing buffer overflows. Buffer flows are a unique problem within the realm of software coding as they can either be an accidental error or they can be created and utilized as a malicious attack. To understand this further, one must first know the purpose of a buffer. In software design, the budder is a region of temporary memory storage, used when data is being transferred from one location to a second. So, a buffer overflow, as known as a buffer overrun, occurs when the data amount is too large for the buffer’s memory capacity. It is this threshold limit that can be forgotten, and as such can be an accident. This is a risk that can occur to any type of software. When this happens, the software program can have a faulty run, create incorrect results or crash. When designed by a hacker to be a malicious attack, a buffer overflow is caused by the hacker overwriting the memory of the program. By changing the execution path of the program, a hacker can trigger a buffer overflow response in order to damage files or expose the data/information. There are more niche buffer overflow attacks that can occur based on the operating system or program language. Some of these include stack- based buffer overflow, heap-based buffer overflow, integer overflow attack, format string attacks or Unicode overflow attacks. The best way to prevent a buffer overflow from occurring, especially as a software designer, is to building in security measures to the program through the programming language, along with conducting regular security tests and audits to correct any errors or weaknesses.
