Security flaws occur as a consequence of sufficient checking and validation of data and error codes in programs. False True or False? Software security is closely related to software quality and reliability. True True or False? A difference between defensive programming and normal practices is that everything is assumed. False True or False? Programmers often make assumptions about the type of inputs a program will receive. True

Defensive programming requires a changed mindset to traditional programming practices. True True or False? To counter XSS attacks a defensive programmer needs to explicitly identify any assumptions as to the form of input and to verify that any input data conform to those assumptions before any use of the data. False True or False? Injection attacks variants can occur whenever one program invokes the services of another program, service, or function and passes to it externally sourced, potentially untrusted information without sufficient inspection and validation of it. True

Cross- site scripting attacks attempt to bypass the browser's security checks to gain elevated access privileges to sensitive data belonging to another site. True True or False? To prevent XSS attacks any user supplied input should be examined and any dangerous code removed or escaped to block its execution. True True or False? An ASCII character can be encoded as a 1 to 4 byte sequence using the UTF-8 encoding. False

There is a problem anticipating and testing for all potential types of non- standard inputs that might be exploited by an attacker to subvert a program. True True or False? Key issues from a software security perspective are whether the implemented algorithm correctly solves the specified problem, whether the machine instructions executed correctly represent the high level algorithm specification, and whether the manipulation of data values in variables is valid and meaningful. True

Without suitable synchronization of accesses it is possible that values may be corrupted, or changes lost, due to over- lapping access, use, and replacement of shared values. True True or False? The correct implementation in the case of an atomic operation is to test separately for the presence of the lockfile and to not always attempt to create it. False
