Q1. What is the meaning of CPENT?
The Certified Penetration Tester (CPENT) curriculum from EC-Council teaches you how to conduct a thorough penetration test in a corporate network environment that must be attacked, exploited, avoided, and defended.
Q2. What is the significance of the CPENT?
With CPENT, you can master advanced windows attacks, pen test IoT and OT systems, access filtered networks, create your exploits, do single and double pivoting, and binary exploitation! Every network must be attacked, exploited, dodged, and defended in some way.
Q3. What are the phases of Network Penetration?
Penetration testing dividing into 5 phases:
Phase 1 – Reconnaissance It is a process of collecting data about the target. It can be performed actively or passively. In this phase, you learn more and more about the target business and its operation. Activities include identifying the target, finding out the target IP address range, network, domain name, mail server, DNS records, etc.
Phase 2 – Scanning This is another crucial phase of penetration testing. In this phase, scanning has been done to identify vulnerabilities in the network and software and OS used by devices. After this activity, the pen tester learns about services running, open ports, firewall detection, vulnerabilities, OS, etc. There are a lot of tools available, both open-source and paid.
Phase 3 – Gaining Access In this phase, the pen tester started executing the attack by gaining access to vulnerable devices and servers. This can be done by using tools.
Phase 4 – Maintaining Access As a pen tester already gained access to a vulnerable system, in this phase, he/she tries to extract as much data and also remain stealthy.
Phase 5 – Covering Tracks In this phase, the pen tester takes all the necessary steps to hide the intrusion and possible controls left behind for future visits. He/she also remove all kinds of logs, uploaded backdoor(s), and anything related to the attack.
Q4. What are the different encryption types?
Symmetric and asymmetric encryption are the two main types. Using keys, symmetric encryption means users and information owners can use the same key to encrypt or decrypt information. Assymetric means there's a private and public key to increase data protection for more sensitive information.
Q5. Explain Penetration testing and why is it important?
A Cybersecurity Specialist aims to discover and exploit weaknesses in a computer system during penetration testing. A simulated attack aims to find any vulnerabilities in a system’s defenses that attackers could exploit. Penetration testing involves Security Analysts attempting to access resources without knowing usernames, passwords, or other traditional methods of access. Only the authorization granted by the organization divides hackers from security specialists.
Q6. What is Information Security?
Information security is how companies protect their systems and information from threats. It can include the processes an organization follows to ensure security, the technology infrastructure and the roles that govern this area.
Q7. Is Cpent better than Oscp?
CPENT's Real Scenario Based Machines makes it more difficult than the OSCP's Simulated Machines. CPENT Course is also designed in such a way to train you to be a perfect Penetration Tester for an Organization not just a CTF Solver.
Q8. Define SQL injection?
It is an attack in which a person adds untrusted data into the program, resulting in the leakage of confidential database information.
Q9. What are the most commonly targeted ports during penetration testing?
For the port scan, you can use the Nmap tool. Following is a list of frequent ports to concentrate on during penetration testing:
- FTP (port 20, 21)
- SSH (port 22)
- Telnet (port 23)
- SMTP (port 25)
- HTTP (port 80)
- NTP (port 123)
- HTTPS (port 443)
Q10. Why should we execute a penetration test if we are currently undertaking vulnerability scanning?
In general, vulnerability scanning identifies flaws based on vulnerability signatures accessible in the scanning program. While penetration testing assists in determining the level of data destruction and risk in the event of a cyber attack.
Q11. What are the three types of pen testing methodologies?
These are the three types:
- Black-box testing
- White-box testing
- Gray-box testing
Black-Box Testing: When a Pen Tester is operating in a black-box environment, he or she has no idea what target(s) they will assault. As a result, pentesting can take a long time, and automated approaches are heavily relied on to expedite the process.
White-Box Testing: Clear-box testing is another term for this type of pen test. In some circumstances, the Pen Tester has a thorough understanding of the Web service they are about to attack, as well as its basic source code.
Gray-Box Testing: This method of pentesting combines black-box and white-box pentesting to uncover weaknesses. That is, they have a good idea of what they’re going to attack.
Q12. What are the teams capable of performing a pentest?
The following are the teams:
- Red team
- Blue team
- Purple team
Red team: This team is in charge of launching the real threat in order to breach the business’s or industry’s defenses and expose any holes that are uncovered.
Blue team: The primary goal of the Blue Team is to prevent any cyber-attacks launched by the Red Team. They adopt a proactive approach while also keeping a high sense of security concern.
Purple team: This is a hybrid of the Red Team and the Blue Team. The Purple Team’s main task is to help both of these teams. As a result, the Purple Team’s Pen Testers cannot be influenced in any way and must retain a neutral perspective.
Q13. When do you use tracert/traceroute?
In case you can’t ping the final destination, tracert will help to identify where the connection stops or gets broken, whether it is the firewall, ISP, router, etc.
Q14. What steps will you take to secure a server?
Secure servers use the SSL (Secure Sockets Layer) protocol for data encryption and decryption to protect data.
- Have a secure password for the root and administrator users.
- Make new users that you use to manage the system.
- Remove remote access from default.
- Configure firewall rules for remote access.
Q15. Can you list some of the common cyber-attacks?
Malware, Phishing, Man in the Middle, Password attacks, DDOS, Ransomware, Drive-by Downloads, Malvertising.
Q16. Differentiate between software testing and penetration testing?
When it comes to software testing, it only deals with the software functionality and nothing related to security. When it comes to penetration testing, it assists in finding any kind of security vulnerabilities.
Q17. What is CIA Triangle?
- Confidentiality : Keeping the information secret.
- Integrity : Keeping the information unaltered.
- Availability : Information is available to the authorized parties at all times.
Q18. What is the difference between Vulnerability Scanning and Penetration testing?
Detects and reports vulnerability
Exploits vulnerability and determines the type of access
Done once a year
Q19. Name the programming languages used for hacking?
Q20. Mention what are the types of password cracking techniques?
- AttackBrute Forcing
Q21. Define adware
A type of malware that will load and display some online or offline Ads in your computer system.
Q22. What is STRIDE?
Spoofing, Tampering, Reputation, Information disclosure, denial of service, Elevation of privilege.
Q23. Define asset
An asset is any data, device, or other component of the environment that supports information related activities.
Q24. Define threat
A threat represents a possible danger to the computer system. It represents something that an organization does not want to happen. A successful exploitation of vulnerability is a threat.
Q25. Define vulnerability
Vulnerability is a flaw or a weakness inside the asset that could be used to gain unauthorized access to it.
Q26. Define risk
A risk is defined as the impact (damage) resulting from the successful compromise of an asset.
Q27. Define Exploit
An exploit is something that takes advantage of vulnerability in an asset to cause unintended or unanticipated behavior in a target system,which would allow an attacker to gain access to data or information.
Q28. What is Encryption?
Encryption is a process of converting plain text (normal message) to meaningless text (Cipher text).
Q29. What is Decryption?
Decryption us a process of converting meaningless text (Cipher text) back to its original form (plain text).
Q30.What is TCP/IP?
TCP/IP (Transmission control protocol/internet protocol) is the basic communication language or protocol of the internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet).
