SOLUTIONS GRADED A+
⩥ race conditions. Answer: A type of software development
vulnerability that occurs when multiple processes or multiple threads
within a process control or share access to a particular resource, and the
correct handling of that resource depends on the proper ordering or
timing of transactions
⩥ input validation. 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. 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. Answer: A type of attack that can occur when
we fail to use strong authentication mechanisms for our applications
⩥ authorization attack. Answer: A type of attack that can occur when we
fail to use authorization best practices for our applications
,⩥ cryptographic attack. 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. 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). 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
⩥ XSRF (cross-site request forgery). Answer: an attack in which the
attacker places a link on a web page in such a way that it will be
automatically executed to initiate a particular activity on another web
page or application where the user is currently authenticated
⩥ clickjacking. Answer: An attack that takes advantage of the graphical
display capabilities of our browser to trick us into clicking on something
we might not otherwise
⩥ server-side attack. 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. Answer: Name the 4 main categories of database
security issues
⩥ web application analysis tool. 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 software versions, and many more such items
⩥ protocol issues. Answer: unauthenticated flaws in network protocols,
authenticated flaws in network protocols, flaws in authentication
protocols
⩥ arbitrary code execution. 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. Answer: An attack that exploits a vulnerability in
software to gain access to resources that the user normally would be
restricted from accessing.
* via SQL injection or local issues
⩥ validating user inputs. Answer: a security best practice for all software
, * the most effective way of mitigating SQL injection attacks
⩥ Nikto (and Wikto). Answer: A web server analysis tool that performs
checks for many common server-side vulnerabilities & creates an index
of all the files and directories it can see on the target web server (a
process known as spidering)
⩥ burp suite. 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. Answer: A type of tool that works by bombarding our
applications with all manner of data and inputs from a wide variety of
sources, in the hope that we can cause the application to fail or to
perform in unexpected ways
⩥ MiniFuzz File Fuzzer. Answer: A tool developed by Microsoft to find
flaws in file-handling source code
⩥ BinScope Binary Analyzer. Answer: A tool developed by Microsoft to
examine source code for general good practices
⩥ SDL Regex Fuzzer. Answer: A tool developed by Microsoft for testing
certain pattern-matching expressions for potential vulnerabilities
