Classic app or web architecture, front event where users input and get output business layer - Answers applies business logic to user inputs and outputs. Where calculations and data is pulled in data layer - Answers manages storage of application related and user data, typically in a database. Where data is connected to databases to pull data into objects and lists. two tier architecture - Answers client and server model three tier architecture - Answers client, middle, and server model input risks - Answers SQL injection, Cross-site scripting, session hijacking Benefits of application architecture - Answers - making changes or errors in one section does not affect the other sections - allows for validation to secure each section - can test separate sections which is good for building how to prevent some SQL injection - Answers input validation Scripting languages - Answers runs sequentially / runs as it reads it.

You have to package it all up before it will run what does XSS stand for - Answers cross site scripting what can XXS do - Answers - redirect to a page that looks like the page it should be but fake - can run scripts that input things that it shouldn't session hijacking (script injection) - Answers -hacker overwrites a sub/function return pointer (which tells the computer where to return once the function/sub is complete) -attacker can set the value to point an address of his/her choosing -more likely with C, C++ -less likely with C#, Java, Perl blacklist - Answers rejecting known bad data / characters. Not the best method cause you are constrained only to what you know is bad whitelist - Answers accepting only valid data sanitize/constrain user inputs by: - Answers blacklist, whitelist, cleaning bad data input validation controls - Answers - do not trust user inputs - sanitize/constrain user inputs -encrypt or mask user inputs -boundary checks and input manipulation control best way to constrain user inputs - Answers whitelist completeness check - Answers verifies that all critical field data are entered. It checks for missing data or blacks Range check - Answers compares entered data to a predetermined acceptable upper and lower limit. limit check - Answers compares entered data to a predetermined upper or lower limit validity check - Answers compares entered data against pre-specified data stored within the computer to determine its validity.

with its own data object properties - Answers variables that contain the data of the objects object methods - Answers stored instructions for behaviors that a particular object understands class variable - Answers - declared inside a class but outside of any method - apply to all objects of that type - usually accessed using class name vs object - ClassNbleName instance variable - Answers - declared inside class method - varies from object to object - accessed using object name - objectNbleName python function - Answers - a block of code that executes some instructions - independent blocks of code that can be called from anywhere python methods - Answers functions tied to objects or classes and need an object or class instance to be invoked python data types - Answers set when you assign a value to them type casting - Answers a programmer explicitly tells the program to set a certain type of data assignment operator - Answers - sets a value to a container - x=5, x += 3 arithmetic operator - Answers - perform arithmetic operations with numeric operands - =,+,-,/ comparison operator - Answers - compares one value to another (true/false) - ==, !=, , logical operator - Answers - logic with multiple comparison (true/false) - and, or, not, in while loop - Answers use for most criteria-based looping, based upon a condition break - Answers stops a loop (including else) continue - Answers skips the rest of this iteration else - Answers command when condition is no longer true for loop - Answers - used to loop through a sequence - used for data collections - used to iterate through strings character-by-character - includes break, continue, else list - Answers - ordered, changeable (add, delete, update) collection of data - written with square brackets tuple - Answers - ordered, un-changeable collection of data - written with parentheses list methods - Answers - append() - clear() - copy() - count() - extend() - index() - insert() - pop() - remove() - reverse() - sort() set - Answers - unordered, un-updateable (add, delete only) collection of data - written with curly brackets
