Introduction to Cyber Security Quiz

Standardizes network protocols, ensuring different hardware and software can communicate.

Handles logical addressing (like IP addresses) and routing of data packets.

Verifies a message's integrity and sender's identity using asymmetric cryptography and hash functions.

Translates IP addresses to MAC addresses (physical hardware addresses).

Reliable, connection-based transport layer protocol.

Translates human-readable domain names (like www.example.com) to IP addresses.

Identifies the network portion of an IP address.

Compares files against a database of known viruses.

SMTP (Simple Mail Transfer Protocol) is responsible for sending and receiving emails.

A firewall's main purpose is to block unauthorized access to a computer network.

A Remote Access Trojan (RAT) allows hackers to control an infected system, giving them administrative privileges.

In a bus topology, all devices are connected in a single linear sequence.

Stealing digital assets or information is considered a cybercrime under Section 65 of the IT Act.

HTTP (Hypertext Transfer Protocol) is the standard protocol used for browsing websites.

AES (Advanced Encryption Standard) is a common cryptographic algorithm used for secure communication over the internet, like in HTTPS.

The assurance that data remains unchanged and accurate, ensuring it hasn't been tampered with.

A mathematical function that transforms data into a fixed-length 'fingerprint' (hash). Any change to the original data results in a different hash.

A cryptographic method using a single key for both encrypting and decrypting data.

Verifying the true identity of a user accessing a system, ensuring they are who they claim to be.

A core information security concept involving Confidentiality, Integrity, and Availability. It guides security policy within organizations.

A method using two keys: a public key for encryption and a private key for decryption.

A cryptographic technique verifying both the sender's identity and the message's integrity.

A connectionless protocol used for sending data packets without guaranteeing delivery or order.

A SIEM (Security Information and Event Management) system collects and analyzes security data from various sources, detecting and responding to security incidents in real-time.

Patch management involves regularly updating software and systems to fix known vulnerabilities and security flaws.

A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a security measure that differentiates humans from automated bots, preventing automated attacks like spam.

A Distributed Denial of Service (DDoS) attack overwhelms a system or network with a massive amount of traffic, making it unavailable to genuine users.

Encryption converts data into an unreadable format, protecting its confidentiality by ensuring only authorized individuals with the decryption key can access it.

A cryptographic key used for encrypting data. Anyone can have access to the public key, but only the corresponding private key can decrypt the data.

A mathematical function that converts data of any size into a unique fixed-length string, called a hash, ensuring data integrity.

This section of the Act addresses offenses related to illegally hacking into a computer system, including unauthorized access and data theft.

A powerful symmetric-key encryption algorithm widely used for securing data transmission over the internet. It uses a single key for both encryption and decryption.

A unique, randomly generated value used in cryptography to prevent replay attacks by ensuring that a message cannot be reused.

A cryptographic attack method that tries every possible combination of a key to decrypt encrypted data. This can take a very long time.

Symmetric encryption uses a single key for both encryption and decryption, while asymmetric encryption uses two keys: a public key for encryption and a private key for decryption.

This is the updated version of the Indian IT Act, 2000. It includes amendments and changes to address emerging technologies and cybercrime threats.

The key objective of cybersecurity is to protect data and systems from unauthorized access, use, disclosure, disruption, modification, or destruction.

It should be difficult to guess, containing a mix of uppercase and lowercase letters, numbers, and symbols.

A firewall acts like a gatekeeper, inspecting incoming and outgoing network traffic, blocking unauthorized access and controlling communication.

This software scans and detects malicious software like viruses, worms, and Trojans, preventing them from infecting your system.

Under Section 67 of the IT Act, possessing, distributing, or creating child pornography is a serious offense.

This cybersecurity principle focuses on granting only the necessary permissions to users to perform their assigned tasks, reducing potential security risks.

This technique verifies user identity based on unique biological characteristics like fingerprints, facial recognition, or iris scans.

A social engineering technique used to trick users into revealing sensitive information like login credentials, passwords, or financial details by impersonating trustworthy sources.

A VPN creates a secure encrypted connection between your device and a server on the internet, protecting your online activities and data from eavesdroppers.
