Entry-Level Penetration Testing Interview Questions

Front 1

What is Penetration Testing and why is it important in cybersecurity?

Back 1

Penetration Testing is the process of testing a computer system, network, or web application to find vulnerabilities that an attacker could exploit. The point of the test is to identify potential vulnerabilities.

Front 2

What is the difference between a Penetration test and a vulnerability assessment?

Back 2

A pen test is a detailed, hands-on examination by a real person that tries to detect and exploit weaknesses in a system, such as a server, PC, network appliance, or web app.

A vulnerability assessment is an automated, high-level scan that looks for and reports any potential vulnerabilities.

Front 4

How do you identify ports open on a remote server?

Back 4

I would use a port scanning tool such as Nmap. Nmap sends packets to the target server and analyzes the responses to determine which ports are open

Front 5

What is sql injection?

Back 5

SQL Injection is a type of attack where malicious sql queries are injected into input fields to manipulate a database.

Front 6

How can a sql injection attack be prevented?

Back 6

You could use prepared statements or input validation

Front 7

What is XSS and how can it be mitigated?

Back 7

XSS malicious scripts injected into websites.

Mitigation: Input validation and Output Encoding

Cross-Site Scripting is a vulnerability that allows attackers to inject malicious scripts into web pages viewed by users.

Reflected XSS is when user input is immediately returned by a web application in some type of response, like a search result or an error message, that includes some or all of the malicious input provided by the user as part of the request, without that data being stored.

Stored XSS is where the the malicious user input is stored on the target server, such as in a database, in a message forum, visitor log, etc. And then a victim is able to retrieve the stored data from the web application.

Mitigation:

Input Validation: Validate and sanitize all user inputs on both client and server sides. Input validation ensures that the data entered by users follows the expected format, and sanitization helps in removing or encoding characters that could be interpreted as code.

Output Encoding: Encode data when it is dynamically generated in the HTML, JavaScript, CSS, or URL context. Properly encoding user inputs prevents browsers from interpreting them as executable scripts.

Front 8

What is a CSA?

Back 8

Hint 9

Business policy

Front 10

How would you crack a password hash?

Back 10

I would use a tool like John or Hashcat to perform various attacks using dictionary attacks, brute-force attacks, and/or rainbow tables. If this were part of a pen test, the rainbow tables would preferably include custom entries inferred by data gleaned during the recon stage of the engagement.

Front 11

You find an open FTP server with anonymous access. What steps would you take to assess its security?

Back 11

I would first check the server configuration to ensure it is necessary to have anonymous access. Then, I would review the files and permissions, and then attempt to upload files (without actually doing so) to test access and see if sensitive data is exposed.

Front 12

How would you conduct a social engineering attack against an organization?

Back 12

I would start by learning the rules of engagement, then do recon using osint such as social media and company web pages. I might then craft phishing emails or use pretexting over the phone to trick employees into revealing sensitive information.

Front 13

How do you communicate technical findings and risks to non-technical stakeholders?

Back 13

I believe in using plain language and not overwhelming them with technical jargon. I would try to use relatable examples to convey complex technical concepts and provide them with graphs, charts, and other visual aids to attempt to illustrate the risks clearly.

Front 14

What is the difference between black box, white box, and grey box testing?

Back 14

Black box is where the functionality of the software is not known ahead of time and there is no internal knowledge of the product. Aka functional testing, aka DAST. This type of testing looks at the software from the user's POV.

White box testing is aka SAST, clear box, or glass box testing. It is when the internal data structures, physical logic flow, and architecture at the level of source code is known ahead of time.

Grey box testing is a combination of the two. It is well-suited for web applications because it factors in a high-level design environment. The internals relevant to the testing are known ahead of time

Front 15

Describe your experience with Penetration Testing tools like Nmap, Metasploit, Burp Suite, etc.

Back 15

I have used nmap, Metasploit, Burp Suite and a number of other applications and programs doing CTFs and in my home lab. I have some experience using msfconsole to check for and run exploits against vulnerabilities, I have used nmap to run port scanning, and I have some experience with Burp Suite using Burp interceptor (intercepts HTTP requests and responses so you can see how the website behaves), Burp repeater (lets you send interesting HTTP or WebSocket messages over and over again which is great for things like trying to identify cookie patterns), Burp intruder (can send different http requests over again and again, inserting different payloads into predefined positions each time) We also cover all 3 as topics in the cybersecurity course that I TA for.

Front 16

What is msfconsole?

Back 16

Msfconsole is a popular interface for using the Metasploit Framework. It is an all-in-one console where you can do just about anything that Metasploit can do.

Front 17

5) test input validation

6) check error handling

7) session management settings

8) API security

9) security headers and CSP (content security policy)

Front 33

What is the difference between Cross-Site Scripting and Cross-Site Request Forgery?

Back 33

CSRF attacks require the authenticated user to be in an active session, while the XSS attack does not.

In an XSS attack, payloads can be stored while CSRF attacks do not typically involve storing payloads on the victim's end (such as in cookies or local storage). The attacks exploit the victim's existing authenticated session to perform actions without their knowledge.

Front 34

Terminology - DAST

Back 34

Dynamic Application Security Testing:

DAST is a “Black-Box” testing, can find security vulnerabilities and weaknesses in a running application by injecting malicious payloads to identify potential flaws that allow for attacks like SQL injections or cross-site scripting (XSS), etc.

DAST tools are especially helpful for detecting:

Input or output validation

Authentication issues

Server configuration mistakes

Front 35

Terminology - SAST

Back 35

Static Application Security Testing:

Static application security testing (SAST), or static analysis, is a testing methodology that analyzes source code to find security vulnerabilities that make your organization's applications susceptible to attack. SAST scans an application before the code is compiled. It's also known as white box testing.

Front 36

First round interview questions for web app pentesting for me were always things like "What's the difference between XSS and CSRF" and "Explain how cookies work for authentication/authorization" and "what is serialization, and how is it used" and "tell me about a time when you...." stuff.

Back 36

XSS involves injecting malicious scripts into a website, whereas CSRF tricks a user into performing unwanted actions on a different website where they are authenticated. Both vulnerabilities require different prevention strategies to ensure web application security. Cross-Site Scripting (XSS): Nature: XSS is a vulnerability that occurs when a web application allows users to inject malicious scripts into web pages viewed by other users. These scripts are then executed in the context of the victims' browsers. Exploitation: Attackers can exploit XSS vulnerabilities to steal sensitive data, session cookies, or perform actions on behalf of the victim without their consent. XSS can be stored (persistent) or reflected (non-persistent) depending on how the malicious script is delivered. Cross-Site Request Forgery (CSRF): Nature: CSRF is a vulnerability that tricks the victim into executing unwanted actions on a different website where the victim is authenticated. This attack takes advantage of the victim's active session on a targeted website. Exploitation: Attackers create malicious requests (e.g., changing account settings) and trick victims into executing these requests without their knowledge. CSRF attacks are typically conducted via social engineering techniques, like tricking users into clicking on a specially crafted link. Differences: Context: XSS attacks target the users' browsers and their interactions with a specific website. CSRF attacks, on the other hand, exploit the trust that a site has in the user's browser. Impact: XSS attacks can steal user data and perform actions on the affected website on behalf of the victim. CSRF attacks focus on making unauthorized requests to a different site where the victim is authenticated, potentially leading to unintended actions. Prevention: Preventing XSS often involves input validation, output encoding, and implementing Content Security Policy (CSP). CSRF prevention methods include anti-CSRF tokens and SameSite cookie attribute, which restricts when cookies are sent with a request. Cookies: Cookies store information from when you visit a website like session IDs and such. When you log into a website, the server verifies your credentials (username/password). the server creates a unique session for you and creates a session ID to store that information. Serialization is the process of converting data structures or objects into a format that can be easily stored, transmitted, or reconstructed at a later time. The serialized data can be in the form of a byte stream, a string, or any other format that suits the specific use case. This process allows data to be saved to a file, sent across a network, or otherwise persisted, and then reconstructed back into its original form when needed. Serialization is used in various scenarios, such as: Data Persistence: Serialized objects can be stored in files or databases. When the program runs again, these objects can be deserialized, reconstructing the original data structures. This is commonly used in applications that need to save user preferences or application state.Network Communication: Objects are serialized before being sent over a network and deserialized on the receiving end. This is crucial for distributed systems and web services where data needs to be transmitted between different systems or components. Caching: Serialized data can be stored in a cache system. When the data is needed, it can be quickly deserialized from the cache instead of being generated or fetched from the original source, saving processing time. Session Management: Serialization is used to maintain user sessions in web applications. Session data is serialized and stored (often in a cookie or server-side storage). When the user makes another request, the session data is deserialized, allowing the web server to recognize the user and maintain their session state. Deep Copy: Serialization is sometimes used to create deep copies of objects. By serializing an object and then deserializing it, you essentially create a new instance of the object, separate from the original, but with the same data.

CSRF prevention methods include anti-CSRF tokens and SameSite cookie attribute, which restricts when cookies are sent with a request. Cookies: Cookies store information from when you visit a website like session IDs and such. When you log into a website, the server verifies your credentials (username/password). the server creates a unique session for you and creates a session ID to store that information. Serialization is the process of converting data structures or objects into a format that can be easily stored, transmitted, or reconstructed at a later time. The serialized data can be in the form of a byte stream, a string, or any other format that suits the specific use case. This process allows data to be saved to a file, sent across a network, or otherwise persisted, and then reconstructed back into its original form when needed. Serialization is used in various scenarios, such as: Data Persistence: Serialized objects can be stored in files or databases. When the program runs again, these objects can be deserialized, reconstructing the original data structures. This is commonly used in applications that need to save user preferences or application state.Network Communication: Objects are serialized before being sent over a network and deserialized on the receiving end. This is crucial for distributed systems and web services where data needs to be transmitted between different systems or components. Caching: Serialized data can be stored in a cache system. When the data is needed, it can be quickly deserialized from the cache instead of being generated or fetched from the original source, saving processing time. Session Management: Serialization is used to maintain user sessions in web applications. Session data is serialized and stored (often in a cookie or server-side storage). When the user makes another request, the session data is deserialized, allowing the web server to recognize the user and maintain their session state. Deep Copy: Serialization is sometimes used to create deep copies of objects. By serializing an object and then deserializing it, you essentially create a new instance of the object, separate from the original, but with the same data.

XSS involves injecting malicious scripts into a website, whereas CSRF tricks a user into performing unwanted actions on a different website where they are authenticated. Both vulnerabilities require different prevention strategies to ensure web application security. Cross-Site Scripting (XSS): Nature: XSS is a vulnerability that occurs when a web application allows users to inject malicious scripts into web pages viewed by other users. These scripts are then executed in the context of the victims' browsers. Exploitation: Attackers can exploit XSS vulnerabilities to steal sensitive data, session cookies, or perform actions on behalf of the victim without their consent. XSS can be stored (persistent) or reflected (non-persistent) depending on how the malicious script is delivered. Cross-Site Request Forgery (CSRF): Nature: CSRF is a vulnerability that tricks the victim into executing unwanted actions on a different website where the victim is authenticated. This attack takes advantage of the victim's active session on a targeted website. Exploitation: Attackers create malicious requests (e.g., changing account settings) and trick victims into executing these requests without their knowledge. CSRF attacks are typically conducted via social engineering techniques, like tricking users into clicking on a specially crafted link. Differences: Context: XSS attacks target the users' browsers and their interactions with a specific website. CSRF attacks, on the other hand, exploit the trust that a site has in the user's browser. Impact: XSS attacks can steal user data and perform actions on the affected website on behalf of the victim.

CSRF attacks focus on making unauthorized requests to a different site where the victim is authenticated, potentially leading to unintended actions. Prevention: Preventing XSS often involves input validation, output encoding, and implementing Content Security Policy (CSP). CSRF prevention methods include anti-CSRF tokens and SameSite cookie attribute, which restricts when cookies are sent with a request. Cookies: Cookies store information from when you visit a website like session IDs and such. When you log into a website, the server verifies your credentials (username/password). the server creates a unique session for you and creates a session ID to store that information. Serialization is the process of converting data structures or objects into a format that can be easily stored, transmitted, or reconstructed at a later time. The serialized data can be in the form of a byte stream, a string, or any other format that suits the specific use case. This process allows data to be saved to a file, sent across a network, or otherwise persisted, and then reconstructed back into its original form when needed. Serialization is used in various scenarios, such as: Data Persistence: Serialized objects can be stored in files or databases. When the program runs again, these objects can be deserialized, reconstructing the original data structures. This is commonly used in applications that need to save user preferences or application state.Network Communication: Objects are serialized before being sent over a network and deserialized on the receiving end. This is crucial for distributed systems and web services where data needs to be transmitted between different systems or components. Caching: Serialized data can be stored in a cache system. When the data is needed, it can be quickly deserialized from the cache instead of being generated or fetched from the original source, saving processing time. Session Management: Serialization is used to maintain user sessions in web applications. Session data is serialized and stored (often in a cookie or server-side storage). When the user makes another request, the session data is deserialized, allowing the web server to recognize the user and maintain their session state. Deep Copy: Serialization is sometimes used to create deep copies of objects. By serializing an object and then deserializing it, you essentially create a new instance of the object, separate from the original, but with the same data.

XSS involves injecting malicious scripts into a website, whereas CSRF tricks a user into performing unwanted actions on a different website where they are authenticated. Both vulnerabilities require different prevention strategies to ensure web application security. Cross-Site Scripting (XSS): Nature: XSS is a vulnerability that occurs when a web application allows users to inject malicious scripts into web pages viewed by other users. These scripts are then executed in the context of the victims' browsers. Exploitation: Attackers can exploit XSS vulnerabilities to steal sensitive data, session cookies, or perform actions on behalf of the victim without their consent. XSS can be stored (persistent) or reflected (non-persistent) depending on how the malicious script is delivered. Cross-Site Request Forgery (CSRF): Nature: CSRF is a vulnerability that tricks the victim into executing unwanted actions on a different website where the victim is authenticated. This attack takes advantage of the victim's active session on a targeted website. Exploitation: Attackers create malicious requests (e.g., changing account settings) and trick victims into executing these requests without their knowledge. CSRF attacks are typically conducted via social engineering techniques, like tricking users into clicking on a specially crafted link.

Differences: Context: XSS attacks target the users' browsers and their interactions with a specific website. CSRF attacks, on the other hand, exploit the trust that a site has in the user's browser. Impact: XSS attacks can steal user data and perform actions on the affected website on behalf of the victim. CSRF attacks focus on making unauthorized requests to a different site where the victim is authenticated, potentially leading to unintended actions. Prevention: Preventing XSS often involves input validation, output encoding, and implementing Content Security Policy (CSP). CSRF prevention methods include anti-CSRF tokens and SameSite cookie attribute, which restricts when cookies are sent with a request. Cookies: Cookies store information from when you visit a website like session IDs and such. When you log into a website, the server verifies your credentials (username/password). the server creates a unique session for you and creates a session ID to store that information. Serialization is the process of converting data structures or objects into a format that can be easily stored, transmitted, or reconstructed at a later time. The serialized data can be in the form of a byte stream, a string, or any other format that suits the specific use case. This process allows data to be saved to a file, sent across a network, or otherwise persisted, and then reconstructed back into its original form when needed. Serialization is used in various scenarios, such as: Data Persistence: Serialized objects can be stored in files or databases. When the program runs again, these objects can be deserialized, reconstructing the original data structures. This is commonly used in applications that need to save user preferences or application state.Network Communication: Objects are serialized before being sent over a network and deserialized on the receiving end. This is crucial for distributed systems and web services where data needs to be transmitted between different systems or components. Caching: Serialized data can be stored in a cache system. When the data is needed, it can be quickly deserialized from the cache instead of being generated or fetched from the original source, saving processing time. Session Management: Serialization is used to maintain user sessions in web applications. Session data is serialized and stored (often in a cookie or server-side storage). When the user makes another request, the session data is deserialized, allowing the web server to recognize the user and maintain their session state. Deep Copy: Serialization is sometimes used to create deep copies of objects. By serializing an object and then deserializing it, you essentially create a new instance of the object, separate from the original, but with the same data.

XSS involves injecting malicious scripts into a website, whereas CSRF tricks a user into performing unwanted actions on a different website where they are authenticated. Both vulnerabilities require different prevention strategies to ensure web application security. Cross-Site Scripting (XSS): Nature: XSS is a vulnerability that occurs when a web application allows users to inject malicious scripts into web pages viewed by other users. These scripts are then executed in the context of the victims' browsers. Exploitation: Attackers can exploit XSS vulnerabilities to steal sensitive data, session cookies, or perform actions on behalf of the victim without their consent. XSS can be stored (persistent) or reflected (non-persistent) depending on how the malicious script is delivered. Cross-Site Request Forgery (CSRF): Nature: CSRF is a vulnerability that tricks the victim into executing unwanted actions on a different website where the victim is authenticated. This attack takes advantage of the victim's active session on a targeted website.

Exploitation: Attackers create malicious requests (e.g., changing account settings) and trick victims into executing these requests without their knowledge. CSRF attacks are typically conducted via social engineering techniques, like tricking users into clicking on a specially crafted link. Differences: Context: XSS attacks target the users' browsers and their interactions with a specific website. CSRF attacks, on the other hand, exploit the trust that a site has in the user's browser. Impact: XSS attacks can steal user data and perform actions on the affected website on behalf of the victim. CSRF attacks focus on making unauthorized requests to a different site where the victim is authenticated, potentially leading to unintended actions. Prevention: Preventing XSS often involves input validation, output encoding, and implementing Content Security Policy (CSP). CSRF prevention methods include anti-CSRF tokens and SameSite cookie attribute, which restricts when cookies are sent with a request. Cookies: Cookies store information from when you visit a website like session IDs and such. When you log into a website, the server verifies your credentials (username/password). the server creates a unique session for you and creates a session ID to store that information. Serialization is the process of converting data structures or objects into a format that can be easily stored, transmitted, or reconstructed at a later time. The serialized data can be in the form of a byte stream, a string, or any other format that suits the specific use case. This process allows data to be saved to a file, sent across a network, or otherwise persisted, and then reconstructed back into its original form when needed. Serialization is used in various scenarios, such as: Data Persistence: Serialized objects can be stored in files or databases. When the program runs again, these objects can be deserialized, reconstructing the original data structures. This is commonly used in applications that need to save user preferences or application state.Network Communication: Objects are serialized before being sent over a network and deserialized on the receiving end. This is crucial for distributed systems and web services where data needs to be transmitted between different systems or components. Caching: Serialized data can be stored in a cache system. When the data is needed, it can be quickly deserialized from the cache instead of being generated or fetched from the original source, saving processing time. Session Management: Serialization is used to maintain user sessions in web applications. Session data is serialized and stored (often in a cookie or server-side storage). When the user makes another request, the session data is deserialized, allowing the web server to recognize the user and maintain their session state. Deep Copy: Serialization is sometimes used to create deep copies of objects. By serializing an object and then deserializing it, you essentially create a new instance of the object, separate from the original, but with the same data.

XSS involves injecting malicious scripts into a website, whereas CSRF tricks a user into performing unwanted actions on a different website where they are authenticated. Both vulnerabilities require different prevention strategies to ensure web application security. Cross-Site Scripting (XSS): Nature: XSS is a vulnerability that occurs when a web application allows users to inject malicious scripts into web pages viewed by other users. These scripts are then executed in the context of the victims' browsers. Exploitation: Attackers can exploit XSS vulnerabilities to steal sensitive data, session cookies, or perform actions on behalf of the victim without their consent. XSS can be stored (persistent) or reflected (non-persistent) depending on how the malicious script is delivered.

HSTS - explain what it is and why is it needed?

Back 40

HSTS (HTTP Strict Transport Security) is a web security policy mechanism that helps to protect websites against man-in-the-middle attacks such as protocol downgrade attacks and cookie hijacking. When a website uses HSTS, it informs web browsers that they should only interact with it using secure HTTPS connections, rather than unencrypted HTTP connections.

HSTS is crucial for ensuring a secure and encrypted connection between users and websites. By mandating the use of HTTPS and protecting against various attacks, HSTS significantly strengthens web security, protects user data, and fosters user trust in online interactions.

You've come across an XSS Vulnerability in the search input of a web application. How would you remediate this?

Back 41

Remediating an XSS (Cross-Site Scripting) vulnerability requires thorough validation and sanitization of user inputs to prevent malicious scripts from executing in users' browsers.

By combining input validation, output encoding, content security policies, and regular security audits, you can effectively remediate XSS vulnerabilities and enhance the overall security posture of your web application.

Input Validation:

Validate all user inputs on the server side. Ensure that the input conforms to the expected format and length. Reject input that doesn’t meet the validation criteria.

Output Encoding:

Encode data when it's output to the web page. Use appropriate encoding functions (like HTML escaping) to convert special characters to their corresponding HTML entities. This prevents the browser from interpreting input as code.

Content Security Policy (CSP):

Implement a Content Security Policy to restrict the sources from which content can be loaded on your web pages. This can prevent the execution of scripts from unauthorized sources.

Sanitization:

If there are specific HTML tags that you want to allow in the search input, use a library that can sanitize input and remove or neutralize any potentially harmful scripts. Be cautious with this approach, as it's hard to predict all possible safe inputs.

HTTPOnly and Secure Flags for Cookies:

If the web application uses cookies, ensure that they have the HttpOnly flag set, which prevents JavaScript from accessing them. Additionally, if the application is served over HTTPS, set the Secure flag on cookies to ensure they are transmitted only over encrypted connections.

Regular Security Audits and Penetration Testing:

Regularly audit your codebase for security vulnerabilities, including XSS. Perform penetration testing to identify and address potential security weaknesses proactively.

Educate Developers:

Ensure that your development team is aware of secure coding practices. Training developers to write secure code is essential in preventing XSS vulnerabilities in the first place.

Security Headers:

Implement security headers like Content Security Policy (CSP) and X-Content-Type-Options to enhance security controls in the browser and prevent malicious scripts from executing.

Web Application Firewall (WAF):

Consider using a Web Application Firewall that can detect and block malicious requests, including those attempting XSS attacks.

What are thick clients and thin clients?

Back 43

Thick clients, also known as fat clients or rich clients, refer to software applications that are installed on a user's computer and rely heavily on the computer's resources. These applications perform most of the processing on the client side (user's computer) rather than relying on a server for processing.

Thin clients are applications that rely heavily on server-side processing and depend on the server to perform most of the data processing and application logic. Thin clients require minimal resources on the user's computer because most of the processing happens on the server.
