D385: Logging and Security Issues Exam
Questions And Answers |Latest 2025 |
Guaranteed Pass.
What are some common debugging techniques? - Answer✔- printing out values of variables
- changing the state ("path") of the program to make it do different things
- stepping through the execution of a program line by line
- breakpoints
- trace points
- stopping the program at certain events
- viewing the output of a program in a debugger window
What are some Python debugging tools? - Answer✔- pdb: most commonly used
- Web-PDB
- wdb
- Pyflame
- objgraph
XML External Entity Attacks - Answer✔- XXE
- when attackers exploit an XML parser to read arbitrary files on your server
- attackers might also be able to read config files, retrieve user information
Insecure Deserialization - Answer✔- serialization is the conversion of an object in a
programming language is saved into a format that can be saved to a database
- DEserialization is when a serialized object is read from a file or the network and converted
back into an object

- INSECURE DESERIALIZATION occurs when an attacker can manipulate the serialized object and
achieve authentication bypass, DOS, or arbitrary code execution
Injection Attacks - Answer✔- when an application cannot properly distinguish between
untrusted user data and code
- typically allows for arbitrary code execution
SQL Injection Attack Mitigation - Answer✔- use parameterized statements
Log Injection Attack Mitigation - Answer✔- prefixing log entries with meta-data (i.e. timestamp)
- validate the entry before accessing or opening
Sensitive Data Leaks - Answer✔- occurs when an application fails to properly protect sensitive
information
- this typically occurs through descriptive response headers, descriptive error messages with
stack traces or database error messages, or revealing comments in HTML files
Cross-site Request Forgery - Answer✔- client-side technique used to attack other users of a
web application
- attackers send HTTP requests that pretend to come from the victim
- attackers then carry out unwanted actions such as changing a password or transferring money
from a bank account
CSRF Mitigation - Answer✔- CSRF tokens
- SameSite cookies
- avoid using GET requests for state-changing actions
SSRF - Answer✔- Server-side Request Forgery
- attacker us able to send requests on behalf of the server
- allows attackers to forge the request signature and assume a privileged position on a network,
bypassing firewall controls, and gaining access to internal services
SSRF Mitigation - Answer✔- never make outbound requests based on user input
- validate external addresses before initiating any outbound requests
PDB - Answer✔- debugger built into the Python standard library
Which three actions are supported by the Python Debugger (PDB)? (Choose 3 answers.) -
Answer✔- establishing breakpoints
- code step throughs
- stack tracing
