input validation - (correct answer) a type of attack that can occur when we fail to
validate the input to our applications or take steps to filter out unexpected or
undesirable content
format string attack - (correct answer) a type of input validation attacks in which
certain print functions within a programming language can be used to manipulate or
view the internal memory of an application
authentication attack - (correct answer) A type of attack that can occur when we
fail to use strong authentication mechanisms for our applications
authorization attack - (correct answer) A type of attack that can occur when we fail
to use authorization best practices for our applications
cryptographic attack - (correct answer) A type of attack that can occur when we fail
to properly design our security mechanisms when implementing cryptographic
controls in our applications
client-side attack - (correct answer) A type of attack that takes advantage of
weaknesses in the software loaded on client machines or one that uses social
engineering techniques to trick us into going along with the attack
XSS (Cross Site Scripting) - (correct answer) an attack carried out by placing code
in the form of a scripting language into a web page or other media that is interpreted
by a client browser

otherwise
server-side attack - (correct answer) A type of attack on the web server that can
target vulnerabilities such as lack of input validation, improper or inadequate
permissions, or extraneous files left on the server from the development process
Protocol issues, unauthenticated access, arbitrary code execution, and privilege
escalation - (correct answer) Name the 4 main categories of database security
issues
web application analysis tool - (correct answer) A type of tool that analyzes web
pages or web-based applications and searches for common flaws such as XSS or
SQL injection flaws, and improperly set permissions, extraneous files, outdated

protocol issues - (correct answer) unauthenticated flaws in network protocols,
authenticated flaws in network protocols, flaws in authentication protocols
arbitrary code execution - (correct answer) An attack that exploits an applications
vulnerability into allowing the attacker to execute commands on a user's computer.
arbitrary code execution in intrinsic or securable SQL elements
Privilege Escalation - (correct answer) An attack that exploits a vulnerability in

accessing.
via SQL injection or local issues
validating user inputs - (correct answer) a security best practice for all software
the most effective way of mitigating SQL injection attacks

burp suite - (correct answer) A well-known GUI web analysis tool that offers a free
and professional version; the pro version includes advanced tools for conducting
more in-depth attacks
fuzzer - (correct answer) A type of tool that works by bombarding our applications

in file-handling source code
BinScope Binary Analyzer - (correct answer) A tool developed by Microsoft to

operating system might be attacked
6 main hardening categories - (correct answer) 1. Removing unnecessary software
2. Removing or turning off unessential services
3. Making alterations to common accounts
