10+ Vapt Engineer Interview Questions and Answers

XSS stands for Cross-Site Scripting. It is a type of security vulnerability that allows attackers to inject malicious scripts into web pages.

• Reflected XSS: The injected script is embedded in the URL and executed when the victim visits the manipulated link.

• Stored XSS: The injected script is permanently stored on the target server and executed whenever the vulnerable page is accessed.

• DOM-based XSS: The vulnerability arises from insecure JavaScript coding that allows the attacke...read more

CSRF is a type of attack where unauthorized commands are transmitted from a user that the web application trusts. SSRF is a type of attack where an attacker can send a crafted request from a vulnerable web application.

• CSRF stands for Cross-Site Request Forgery, while SSRF stands for Server-Side Request Forgery.

• CSRF involves tricking a user into making a request they did not intend to, while SSRF involves an attacker sending a crafted request from a vulnerable web application....read more

Network VAPT is conducted by identifying vulnerabilities in the network and testing its security measures.

• The process involves identifying potential vulnerabilities in the network infrastructure

• Penetration testing is conducted to simulate attacks and test the effectiveness of security measures

• Vulnerability assessment is done to identify weaknesses in the network

• The results are analyzed and recommendations are made to improve the network security

• Examples of tools used in netwo...read more

IDOR, DOM XSS, and Nessus are common security vulnerabilities and tools used in penetration testing.

• IDOR stands for Insecure Direct Object Reference, where an attacker can access unauthorized data by manipulating object references.

• DOM XSS (Cross-Site Scripting) is a type of XSS attack that occurs in the Document Object Model.

• Nessus is a popular vulnerability scanner used in penetration testing to identify security vulnerabilities in a network.

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

• XSS attacks can be used to steal sensitive information, such as login credentials or personal data.

• Attackers can also use XSS to hijack user sessions, redirect users to malicious websites, or deface web pages.

• There are three types of XSS attacks: stored, reflected, and DOM-based.

• Preventing XSS attacks involves input validation, ...read more

Insecure deserialization is a vulnerability where an attacker can manipulate serialized data to execute arbitrary code.

• Insecure deserialization occurs when untrusted data is deserialized without proper validation.

• Attackers can exploit this vulnerability to execute malicious code, escalate privileges, or tamper with data.

• Examples include modifying serialized data to change user permissions or inject malware into the application.

SAST stands for Static Application Security Testing and DAST stands for Dynamic Application Security Testing.

• SAST involves analyzing the application's source code or binary code for security vulnerabilities without executing the code.

• DAST involves testing the application while it is running to identify security vulnerabilities by sending malicious input.

• SAST is typically performed earlier in the development cycle while DAST is performed later in the cycle.

• Examples of SAST too...read more

Cross site scripting (XSS) is a type of security vulnerability typically found in web applications where malicious scripts are injected into trusted websites.

• XSS allows attackers to execute scripts in the victim's browser, potentially stealing sensitive information or altering the website's content.

• There are three main types of XSS: stored XSS, reflected XSS, and DOM-based XSS.

• Preventing XSS involves input validation, output encoding, and using security mechanisms like Conten...read more

Cache Deceptions involve manipulating cache contents, while Cache Poisoning involves injecting malicious data into cache.

• Cache Deceptions involve tricking the cache into storing false data to be used later for malicious purposes.

• Cache Poisoning involves injecting malicious data into the cache to be used by attackers.

• Examples of Cache Deceptions include manipulating cache eviction policies to store false data, while examples of Cache Poisoning include injecting fake DNS record...read more

VAPT process involves vulnerability assessment and penetration testing to identify and address security weaknesses in a system.

• Vulnerability Assessment: Identifying and prioritizing vulnerabilities in a system.

• Penetration Testing: Simulating attacks to exploit vulnerabilities and assess the security posture.

• Reporting: Documenting findings, risks, and recommendations for remediation.

• Remediation: Fixing identified vulnerabilities to improve security.

• Re-testing: Confirming that ...read more
