Information Security Engineer is a role that has come into the limelight recently. Nowadays, every organization wants to appoint Information Security Engineers as they can provide them with a complete security solution for data and information.
Infosys Security Engineer interview questions are compiled to test your basic knowledge of Information Security Engineering. The more you practice these questions, the better prepared you will be for your interview.
The need for Information Security Engineers is increasing every year. With the rapid growth of the Internet and its mobile applications, there has been an increased demand for Information Security Engineers to protect data from unauthorized access or modification. The job market for this area is expected to grow at a rate of 11% from 2018 to 2023, which is much faster than average market growth.
The following are some of the frequently asked basic, intermediate, and advanced Infosys interview questions. These top Infosys interview questions for freshers will help you land a job.
Listed below are some of the frequently asked basic Information Security Engineer interview questions:
Confidentiality, integrity, and availability are three fundamental concepts of information security.
A confidentiality policy limits access to sensitive information, an integrity policy ensures the information is trustworthy and accurate, and an availability policy guarantees that authorized users have reliable access to the information.
Cryptography involves studying and practicing techniques for securing communication when adversarial behavior is present. It generally concerns the construction and analysis of protocols designed to keep private information from being read by third parties or the general public.
Data can be authenticated using hashing algorithms. The writer uses a hash to secure the document after it has been completed. A hash serves as a sort of seal of approval. Hashes can be generated by recipients and compared to originals. The data is considered genuine if the two are equal.
Using steganography, you can protect confidential data within a seemingly ordinary file or message.
In a firewall, incoming and outgoing network traffic is monitored and filtered in accordance with the security policies already in place in an organization.
A spoofing attack is called a spoofing attack when a person or program successfully copies or spoofs another’s identity to gain an unfair advantage.
Role Based Access Control (RBAC), Discretionary Access Control (DAC), and Mandatory Access Control (MAC) are the three main kinds of access control systems.
Listed below are some of the frequently asked intermediate Information Security Engineer interview questions:
A threat model describes potential threats, such as structural vulnerabilities or inadequate safeguards, and prioritizes countermeasures.
There are four different types of Information Security:
Because it helps protect IT systems from cyberattacks and data breaches.
In a Denial-of-Service (DoS) attack, a machine or network is shut down, making it unavailable to its intended users.
In password cracking, a computer or network resource’s forgotten password is identified using a program.
A single key encrypts and decrypts both electronic data and is used for both encryption and decryption using symmetric encryption.
SQL injection is a technique for injecting code into a database that might cause it to crash. Web hackers often use SQL injection techniques to hack websites. Through web page input, malicious code can be injected into SQL statements.
Honeypots are cybersecurity mechanisms that are used to distract cybercriminals from legitimate targets by creating a fabricated attack target. Aside from collecting intelligence, they also determine an adversary’s identity, methods, and motivations.
Listed below are some of the advanced Information Security Engineer interview questions:
In addition to providing end-to-end encryption of data transmitted over the Internet, TLS is a cryptographic protocol that offers end-to-end tracking capabilities.
There are four types of fuzzing:
Source code analysis helps to enhance the security and quality of the source code.
Network security is provided by traffic filtering, which filters traffic according to various criteria. A traffic filter is a distributed denial-of-service (DDoS) prevention device that filters traffic coming into a network, limits rate limits, looks up reverse addresses, and monitors traffic on the network.
Static analysis is a method of debugging by analyzing the source code without running the program. Developers benefit from this by gaining a deeper understanding of their code base and by ensuring its safety and security.
Dynamic analysis tests and evaluates a program by executing data in real-time. Instead of repeatedly inspecting the code offline, the goal is to discover errors while the program is running.
This process allows for high-quality, low-cost software to be produced quickly through a structured process known as Software Development Life Cycle (SDLC). As part of the SDLC, superior software must be developed and delivered that meets and exceeds all customer requirements and expectations.
There are typically six to eight steps in the process: Planning, Requirements, Design, Build, Documentation, Test, Deployment, and Maintenance. It depends on the project’s scope whether some steps are combined, split, or omitted. Every software development project should include these core components.
Web servers send browsers small files containing unique identifiers known as cookies. The cookies are sent back to the server when your browser requests a new page. Basically, it allows websites to remember things about you online, like your preferences and habits.
Businesses prepare business continuity plans to ensure that they will remain operational during unplanned service disruptions.
Disaster recovery plans (DRPs) are formal documents created by organizations to outline how to respond to unplanned incidents like natural disasters, power outages, and cyberattacks.
