Cybersecurity is the only IT field that hasn't been hit by a recession. Due to high demand, there is also competition for jobs in cybersecurity, so you need to be the best. While possessing the necessary cybersecurity skills is half the battle, cracking the interview is another story altogether. Here is a list of top Cybersecurity interview questions and answers prepared by experts at InfosecTrain that will help you ace the interview. And the questions are:
1. What is encryption?
Encryption is the process of transforming the plaintext (Eg: Hello) into an unreadable format like a random arrangement of alphabets, numbers, or symbols (Eg: 2dosm). With the help of encryption, we can securely send the message to the intended target. And only that target can read the message with the help of a key.
2. What is encoding?
The encoding process ensures that data is formatted correctly, allowing applications and recipients to interpret it correctly. For example, it is like transforming data into a scheme that can be understood easily so that communications can take place.
3. What is hashing?
Hashing maintains data integrity. The hash function generates a string of data based on the information stored. The hash generated after transmission can then be compared to the original data to verify that the data has not been changed. It should not be trusted if they do not match because the information has been altered and cannot be trusted.
4. What are the various layers of the OSI model?
- Application layer
- Presentation layer
- Session layer
- Transport layer
- Network layer
- Data Link layer
- Physical layer
5. What do you know about cross-site scripting?
An XSS (or cross-site scripting) attack involves client-side code injection. When an attacker runs malicious scripts, they perform negative actions on websites or applications. It allows the attacker to carry out tasks that they would otherwise not be authorized to carry out.
Web applications are predisposed to cross-site scripting attacks today, mostly because vulnerabilities are unintentionally written into their code. Security considerations are ignored during the development cycle, and the resulting vulnerabilities have a serious negative impact on the business.
6. What is a vulnerability assessment?
The vulnerability assessment process is used to identify flaws in target systems. In this case, the organization knows that the system or network has flaws and wants to find the weaknesses and will fix them according to priority.
7. List a few common cyberattacks that you know?
A few common cyber attacks known are:
- Phishing (including Smishing, Vishing)
- Malware
- DDoS
- Password Attacks
- Malvertising
- Drive-By Downloads
- Man in the Middle
- Rogue Software
8. What are the different response codes we usually receive from a web application?
1xx – Informational responses
2xx – Success
3xx – Redirection
4xx – Client-side error
5xx – Server-side error
9. What can we do to prevent the brute-force attack?
If you want to avoid brute-force attacks, you need to make sure that password best practices are in place and strictly followed. In basic terms, you can achieve this by enforcing policy at the system level so that even if a user tries to circumvent these measures by using a weak password, they will not be able to do so.
10. List a few port scanning techniques?
- Ping Scan
- UDP
- TCP Half-Open
- Stealth Scanning
- TCP Connect
