Top Red Team Expert Interview Questions and Answer

Overview of Red Team

Cyber security experts are in greater demand due to the increased sensitivity of data and protection along with a shift in perspective towards digital security around the world. As threats become more complex, simple protections are no longer sufficient to tackle the same. To uncover all of the vulnerabilities that could be exploited, a Red Team penetration testing professional is required to conduct offensive penetration testing. The Red Team professionals are self-sufficient in companies and are only hired by those who are willing to have their defenses tested.

Interview questions
1. Describe the concept of information security.
As the name implies, information security, or Infosec, is the process of protecting information by reducing the risks associated with it. Basically, it’s the process of preventing unauthorized access to or use of information.

2. Explain the differences between symmetric and asymmetric encryption.

Symmetric Encryption	Asymmetric Encryption
It takes a single key to encrypt and decrypt data Code text is similar to or smaller than plain text When it comes to symmetric, the process is lightning fast Whenever a huge volume of data needs to be transferred, this method is utilized	It takes two keys, one to encrypt and one to decrypt The encrypted text is the same or greater than the initial plain text This encryption method is difficult and time-consuming It’s used to send little amounts of data.

3. How do you define the word “vulnerability”?
Vulnerability can be defined as insecurity of software that refers to its sensitivity to cybercrime or its inability to remain completely secure. Vulnerable software contains security flaws that can be exploited by malicious individuals to gain access to the software and create disruption.

4. In the case of a physical intrusion by your Red Team, at what point does someone challenging them become a negotiated settlement?
It’s not unusual for IRM (Information Right Management) agents to carry letters outlining the purpose of their mission as well as the contact information of the person who commissioned the Red Team. The individual concerned would be notified if a compromise occurred.

5. Is there any advantage to having a third party conduct a Red Team exercise rather than an in-house Red Team?
An independent Red Team has a distinct benefit over both approaches in that they can give you an honest look at your organization from the perspective of someone who doesn’t know you very well. It’s also likely that an outsider has broader cross-industry experience, which may be incredibly valuable – and they’re likely to have more tools than an in-house team has.

6. How often and when should Red Team operations be performed?
This is highly dependent on various factors, including the size or organization, risk appetite, industry sector, and so on. But this is usually done over several months.

7. Describe the role of Attack Surface Management as a first-level engagement inside the Red Team.
Services such as Vulnerability Management are offered by attack surface management. It can also scan external, internal, and cloud networks, as well as online applications, to find out what’s going on.

8. In what way is Pen testing different from attack surface management?
In contrast to Vulnerability Management and Attack Surface Management, Penetration Testing really seeks to exploit the vulnerabilities that have been identified by Vulnerability and Attack Surface Management. Depending on the type of engagement, a Penetration Test will validate a variety of technological security safeguards. Look at things like multifactor authentication, and make sure it’s enforced, and maybe look at increased password security, network segmentation, and also make sure things like your endpoint detection system are on point in spotting some of the major risks that are out there.

9. What are some of the most common Red Team strategies?
Red team assessors will often go beyond the test in the following ways:

Media manipulation using email and phone:  Fraudulent email messages become much more believable with a little bit of background information. Most often, this low-growing fruit is just one of many attempts that lead to the goal.

Exploiting network services: An adversary can get access to information unavailable networks or sensitive information by exploiting unencrypted or insecure network services.

The exploitation of physical facilities: Most people prefer to avoid conflict. It’s often as simple as the following someone through a door to obtain entry to a secure facility.

Use of the Application-layer: An attacker’s initial impression of an organization’s network perimeter is often its web apps. For example, cross-site scripting (XSS) and SQL injection are types of vulnerabilities in Web applications.

10. How do you prepare for a Red Team assessment?
To help you choose your assessment’s aims, here are some questions to ask yourself.

1. What may go wrong in my organization that would have a negative impact on my reputation or revenue?
2. What is the infrastructure that is used throughout the organization as a whole?
3. When it comes to data and technology, what are the most valuable assets in the business and what are the ramifications if those assets are compromised?

11. Why do you filter ports on the firewall?
Ports are filtered on the firewall to block specific malware and safeguard the network from superfluous traffic. Port 21 (FTP) may be blocked by some corporations if the company isn’t hosting or allowing FTP communications.

12. When should you use traceroute/tracert?
If you can’t ping the end destination, tracert will help you figure out where the connection breaks, whether it’s a firewall, ISP, or router.

13. With the Diffie Hellman Exchange, what kind of penetration may be achieved?
Diffie-Hellman exchanges are vulnerable to a man-in-the-middle attack since neither side is verified. Users can add encryption and authentication by using SSL or encryption between messages.

14. Is there a way to make a website more secure?
Here’s how to safeguard a website:

• Purchasing a basic Secure Sockets Layer certificate is an important step
• Anti-malware software should be used to detect and prevent malicious intrusions
• Ensure that your passwords are difficult to guess
• Prepare for the worst-case scenario by creating regular backups of your data.

15. Is Network Penetration Testing and Network Vulnerability Assessment the same thing?

Vulnerability assessment	Penetration testing
Vulnerability assessment aims to discover weaknesses in a network’s infrastructure. this technique is used to determine how vulnerable a network is to different vulnerabilities	Vulnerability assessments uncover weaknesses in a network, while penetration testing attempts to exploit those vulnerabilities in order to gain entry into the system

16. In what ways is it important to regularly assess the security of your networks?
To maintain a safe network, it is vital to conduct regular checks as new security concerns and flaws with different products are revealed on a daily basis. When it comes to being safe online, the best strategy is to stay one step ahead of criminals at all times.

17. What exactly are red team tools?
An enterprise’s “Red Team” is a collection of security specialists authorised and organised to imitate a possible adversary’s attack or exploitation capabilities against the enterprise’s security postures.

18. Describe Blue Team in cybersecurity?
Cyber security testing involves blue teams that evaluate organisational security environments and defend them from the red teams. In a contained way, these red teams act as attackers, recognising security vulnerabilities and trying to launch attacks. Both teams work together to shed light on an organization’s true security state.

19. What are the objectives of a Pentesting exercise?
The following are the objectives:

1. To ensure that the organization’s security policies are being adhered
2. Ascertain if employees are proactive and aware of their security environment
3. A thorough understanding of how a business entity can respond to and recover from a massive security breach

20. Exactly what is a Cryptographer?
Due to an increased number of security breaches, it is better to transfer the same data into something more circuitous using cryptography. Cryptography is the process of encrypting and decrypting data in such a way that only the person who receives the code can decrypt it. A cryptographer is a person responsible for the cryptography process.

21. What is the definition of a Brute Force Attack?
A brute force attack is a type of hacking technique that relies on experimentation to crack passwords, login details, and encryption techniques. It is a simple yet dependable method for gaining unauthorized access to personal accounts as well as systems and networks within organizations. The hacker attempts a variety of usernames and passwords, frequently using a computer to try a large number of sequences until they uncover the correct login credentials.

22. Define Steganography?
In Steganography, a message is hidden and then delivered to a recipient without the recipient being able to identify the message. However, the message is encrypted in cryptography and the presence of the message itself is disguised in steganography.

23. What are the three different kinds of pentesting methodologies?
The three categories are as follows:

Black-Box Testing: If the pentester is working in a black-box situation, he or she will have no idea what target(s) they are going to attack. Therefore, pentesting can take a long time, and automated methods are largely depended upon to speed things up.

White-Box Testing:  This type of pentest is also referred to as clear-box testing. In these cases, the pentester has some detailed knowledge of the Web service that they are about to attack and its fundamental source code.

Gray-Box Testing: Black-box and white-box pentesting are combined in this type of pentesting to find vulnerabilities. Meaning that they have some advanced understanding of what they’re going to be attacking.

24. What is a Purple Team?
Blue Team and Red Team are combined in this team. For example, they have access to the Blue Team’s security arsenal and know what the Red Team’s offensive plans are. The Purple Team’s major responsibility is to assist both of these teams. They are therefore obligated to maintain a neutral point of view at all times.

25. What exactly is data leakage?
Unintentional or deliberate data leaking from a corporate database to an external storage device is known as data leakage. Low and slow data theft is a huge problem for data security, and the damage to any organization, regardless of its size or industry, can be serious if it is not addressed.
