Understanding Application Attacks

The video tutorial covers various application attacks, including injection attacks, buffer overflow, replay attacks, privilege escalation, cross-site request forgery, and directory traversal. It explains how these attacks work, their potential impact, and the importance of proper security measures to prevent them. The tutorial emphasizes the need for input validation, patching vulnerabilities, and using security features like cryptographic tokens to protect applications.

What is a common type of injection attack that involves inserting malicious code into SQL queries?

• LDAP Injection

• HTML Injection

• SQL Injection

• XML Injection

In a buffer overflow attack, what happens when more data is added than a variable can hold?

• The extra data overflows into adjacent memory

• The application encrypts the data

• The application automatically corrects the overflow

• The data is ignored

What is the main challenge for attackers when performing a replay attack?

• Encrypting the data

• Bypassing antivirus software

• Capturing the information to replay

• Finding the right network to attack

What is privilege escalation in the context of application attacks?

• Accessing the application without a password

• Decreasing the security level of an application

• Increasing the privileges of a user within an application

• Gaining unauthorized access to a network

What is the primary goal of a privilege escalation attack?

• To redirect network traffic

• To delete application data

• To obtain higher access rights within an application

• To gain access to a user's email

How can web-based applications prevent cross-site request forgery (CSRF) attacks?

• By using cryptographic tokens

• By disabling cookies

• By using a firewall

• By encrypting all data

What is a cross-site request forgery (CSRF) attack?

• An attack that involves phishing emails

• An attack that uses malware to gain access

• An attack that targets the server's database

• An attack that exploits the trust a website has in a user's browser

What is the purpose of using a cryptographic token in web applications?

• To authenticate user sessions

• To log user activities

• To prevent unauthorized requests

• To encrypt user passwords

What is a directory traversal attack?

• An attack that modifies the directory structure of a server

• An attack that exploits web server misconfigurations to access restricted directories

• An attack that deletes files from a server

• An attack that encrypts server data

Which URL pattern is indicative of a directory traversal attempt?

• ../

• /etc/passwd

• /home/user/

• /var/www/
