10+ Cyber Security Intern Interview Questions and Answers

The layers in a network system refer to the different levels of protocols and technologies that work together to transmit data.

• Physical layer: Deals with the physical connection between devices (e.g. cables, switches)

• Data link layer: Responsible for node-to-node communication (e.g. Ethernet)

• Network layer: Manages routing and addressing (e.g. IP)

• Transport layer: Ensures end-to-end communication (e.g. TCP)

• Application layer: Provides interfaces for applications to access network...read more

White hat hackers are ethical hackers who use their skills to help organizations improve their security.

• White hat hackers are ethical hackers who have permission to test the security of systems and networks.

• They help organizations by identifying vulnerabilities and providing recommendations for improving security.

• White hat hackers often work as security consultants, penetration testers, or security researchers.

• Examples of white hat hackers include Kevin Mitnick, Charlie Mille...read more

TCP is connection-oriented, reliable protocol while UDP is connectionless, unreliable protocol. TCP/IP model has 4 layers - Application, Transport, Internet, Link.

• TCP is connection-oriented, ensures data delivery in order, and provides error-checking and retransmission of lost packets (e.g. email, web browsing)

• UDP is connectionless, faster but less reliable, used for real-time applications where speed is more important than accuracy (e.g. video streaming, online gaming)

• TCP/IP...read more

Explanation of 5 vulnerabilities in OWASP Top 10

• Injection: Allows attackers to inject malicious code into an application, such as SQL injection or command injection.

• Broken Authentication: Weak authentication methods can lead to unauthorized access to sensitive data.

• Sensitive Data Exposure: Failure to properly protect sensitive data can result in data breaches.

• XML External Entities (XXE): Attackers can exploit vulnerable XML processors to access sensitive data or execute remot...read more

Wireshark is a network protocol analyzer used for troubleshooting, analysis, and security purposes.

• Wireshark captures and analyzes network traffic in real-time.

• It helps in identifying network problems, security vulnerabilities, and malicious activities.

• Users can view packet details, filter traffic, and generate reports for analysis.

• Wireshark is commonly used by network administrators, security professionals, and developers.

• Example: Using Wireshark to analyze a network attack ...read more

SOC is a team responsible for monitoring and responding to security incidents, while SIEM is a tool used to collect, analyze, and correlate security data.

• SOC (Security Operations Center) is a team of cybersecurity professionals responsible for monitoring, detecting, analyzing, and responding to security incidents.

• SIEM (Security Information and Event Management) is a software solution that collects, analyzes, and correlates security data from various sources to provide actiona...read more

XSS attack is a type of cyber attack where attackers inject malicious scripts into web pages viewed by other users.

• XSS stands for Cross-Site Scripting.

• Attackers inject malicious scripts into web pages viewed by other users.

• These scripts can steal sensitive information, deface websites, redirect users to malicious sites, etc.

• There are three types of XSS attacks: Stored XSS, Reflected XSS, and DOM-based XSS.

• Example: Attacker injects a script into a comment section of a website,...read more

The OSI Model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.

• The OSI Model stands for Open Systems Interconnection Model.

• It divides network communication into seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and interacts with adjacent layers to facilitate communication.

• For example, the Physical layer deals with the physical co...read more

Identifying hidden information is crucial in cyber security to uncover potential threats or vulnerabilities.

• Look for hidden files or directories on a system

• Check for hidden code or malware within legitimate files

• Analyze network traffic for hidden communication channels

• Examine metadata of files for hidden information

OWASP Top 10 is a list of the top 10 most critical web application security risks.

• Published by the Open Web Application Security Project (OWASP)

• Helps organizations prioritize their security efforts

• Includes vulnerabilities like injection, broken authentication, and sensitive data exposure
