Questions and Answers

What is the main difference between CSRF and XSS?

  • CSRF occurs when a user is logged in and visits a malicious website, while XSS involves attackers entering specially crafted input. (correct)
  • XSS involves executing malicious code on the user's browser, while CSRF manipulates input to execute unintended queries.
  • CSRF manipulates input data to execute queries, while XSS sends unwanted requests to authenticated websites.
  • XSS happens when the user opens multiple tabs, while CSRF requires the user to fully log out of websites.
  • How can CSRF be mitigated according to the text?

  • Expiring session variables as quickly as possible (correct)
  • Reauthenticating users for requests using one-time passwords
  • Sanitising user inputs and encoding them for HTML display
  • Allowing multiple tabs open during sensitive transactions
  • Which statement best describes SQL injection?

  • Sending unwanted requests to authenticated websites
  • Executing malicious code on the user's browser
  • Attackers manipulate input data to execute queries other than intended (correct)
  • Attackers enter specially crafted input to execute malicious actions
  • How can XSS be mitigated based on the information provided?

    Study Notes

    security threats and mitigation techniques

    • CSRF (Cross-Site Request Forgery) is an attack where a user is tricked into performing an unintended action on a web application they are authenticated to
    • The main difference between CSRF and XSS (Cross-Site Scripting) is that CSRF attacks exploit the user's authenticated state, while XSS attacks inject malicious scripts into a website

    CSRF mitigation techniques

    • Validate requests to ensure they come from the user and not an attacker
    • Use CSRF tokens to verify the authenticity of requests
    • Use the Same-Origin Policy to restrict access to resources

    SQL injection

    • SQL injection is a type of attack where an attacker inserts malicious SQL code to access or modify sensitive data

    XSS mitigation techniques

    • Validate and sanitize user input to prevent malicious scripts
    • Use output encoding to ensure user input is not executed by the browser
    • Implement Content Security Policy (CSP) to define allowed sources of content

    Firewalls

    Types of firewalls

    • Hardware firewalls are more scalable than software firewalls
    • Software firewalls are more flexible and can be customized
    • Hybrid firewalls combine the benefits of hardware and software firewalls
    • Advantages of software firewalls include flexibility and customization options
    • Hybrid firewalls provide both scalability and flexibility

    Logging

    • Logging is important for security teams to identify and respond to security incidents
    • Logging helps track user activity, system events, and security alerts

    Port scanning

    • Port scanning is a technique used in ethical hacking to identify open ports and services running on a network

    DNS

    • DNS (Domain Name System) resolves domain names to IP addresses through a hierarchical system of servers
    • DNS works by recursively querying DNS servers until the IP address is resolved

    Matching exercises

    • CSRF: Validate requests, use CSRF tokens, and Same-Origin Policy
    • XSS: Validate and sanitize user input, use output encoding, and implement CSP
    • SQL injection: Validate user input, use parameterized queries, and limit database privileges
    • Firewall types: Hardware (scalable), software (flexible), hybrid (scalability and flexibility)
    • Log types: System logs, application logs, security logs
    • Network security concepts: Firewall, IDS, IPS, DNS, IP addresses
    • Security terms: CSRF, XSS, SQL injection, Firewall, IDS, IPS
