Cyber Security Analyst Lead Interview Questions and Answers

We follow a systematic approach for performing VAPT on web applications, mobile applications, and network infra with the provided URL/IP address.

• First, conduct a thorough reconnaissance phase to gather information about the target.

• Next, perform vulnerability scanning to identify potential security weaknesses.

• Then, conduct penetration testing to exploit the identified vulnerabilities.

• Finally, provide a detailed report with recommendations for remediation.

• Examples: Using tools ...read more

Privilege escalation can be achieved by exploiting vulnerabilities in the system or using social engineering techniques.

• Exploit vulnerabilities in the system to gain higher privileges

• Use social engineering techniques to trick users into granting higher privileges

• Utilize known privilege escalation techniques such as DLL hijacking or abusing misconfigured permissions

OWASP Top 10 identifies the most critical web application security risks to help organizations improve their security posture.

• Provides a framework for understanding common vulnerabilities like SQL Injection and Cross-Site Scripting (XSS).

• Helps prioritize security efforts by focusing on the most prevalent and impactful risks.

• Facilitates communication between technical and non-technical stakeholders regarding security issues.

• Encourages the adoption of secure coding practices an...read more

Different attacks have unique characteristics and targets, such as CSRF/SSRF, LFI/RFI, Stored XSS/DOM based XSS.

• CSRF (Cross-Site Request Forgery) - attacker tricks a user into performing actions on a website without their knowledge

• SSRF (Server-Side Request Forgery) - attacker can make the server perform requests to other servers

• LFI (Local File Inclusion) - attacker can include files on a server through a web browser

• RFI (Remote File Inclusion) - attacker can include files from...read more

Common ports for network communication

• Port 80 - HTTP (Hypertext Transfer Protocol)

• Port 443 - HTTPS (Hypertext Transfer Protocol Secure)

• Port 25 - SMTP (Simple Mail Transfer Protocol)

• Port 22 - SSH (Secure Shell)

• Port 21 - FTP (File Transfer Protocol)

Bruteforce is a method used to crack passwords by systematically trying all possible combinations until the correct one is found.

• Use automated tools like Hydra or Burp Suite to try different combinations of usernames and passwords

• Start with common passwords and then move on to more complex ones

• Bruteforcing can be time-consuming and may trigger account lockouts if not done carefully

Cross-Site Scripting (XSS) is a type of security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users.

• Reflected XSS: occurs when the malicious script is reflected off a web server, such as in search results or error messages

• Stored XSS: the injected script is permanently stored on the target server, such as in a comment section or database

• DOM-based XSS: the attack occurs in the Document Object Model (DOM) rather than the server-s...read more

Cybersecurity is the practice of protecting systems, networks, and data from digital attacks.

• Cybersecurity involves implementing measures to prevent unauthorized access to information.

• It includes technologies, processes, and practices designed to protect networks, devices, and data from cyber threats.

• Examples of cybersecurity measures include firewalls, antivirus software, encryption, and multi-factor authentication.
