Right OPTION is (d) Geographic location of a user

Easiest explanation: The method USED to capture data PACKETS through any target NETWORK is called sniffing. The various objectives of sniffing for hackers are fetching passwords, email texts and the TYPE of files transferred.

Right CHOICE is (d) Sniffers

To elaborate: Sniffing is data interception method USED by cyber-criminals. Sniffers are programs or DEVICES that CAPTURE vital INFORMATION from the target network or particular network.

Correct ANSWER is (b) wiretapping

Easiest explanation: SNIFFING which is also known as wiretapping is data interception method used by hackers. It is a technique used for monitoring & CAPTURING all data PACKETS PASSING through any target network.

The correct answer is (c) Sniffing

The best I can explain: Sniffing is data interception method USED by hackers. Sniffing is the method used to MONITOR & capture all data packets PASSING through any target NETWORK using sniffing tools.

Correct choice is (d) Monkey in the Middle

The explanation is: Phishing is an internet scam done by cyber-criminals where the user is convinced digitally to provide CONFIDENTIAL INFORMATION. There are different types of phishing. Some of them are Spear phishing, deceptive phishing, whaling, PHARMING, vishing.

The correct answer is (c) SEARCH engine

The best explanation: Search engine PHISHING is that TYPE of phishing where the construction of a fake WEBPAGE is done for targeting definite keywords & waiting for the searcher to land on the fake webpage.

Right ANSWER is (b) Vishing

To EXPLAIN I WOULD say: Phishing occurs when a cyber-criminal masquerade as a trusted entity. Vishing refers to phishing performed where the phishing is DONE through voice hence called vishing = voice + phishing.

Correct answer is (d) SPEAR PHISHING

To explain: In spear phishing, hackers USUALLY targeted specifically where the emails are exclusively designed to TARGET any particular user. It occurs when an attacker MASQUERADES the victim a trusted party.

The correct answer is (d) Vishing

For explanation I WOULD say: Phishers often develop illegitimate websites for tricking users & FILLING their PERSONAL DATA. Vishing refers to phishing performed over smart-phone by calling. As the phishing is done through voice so it is called vishing = voice + phishing.

Right ANSWER is (b) Email-based phishing

Easy EXPLANATION: In email phishing, the email is fashioned as if it has been sent from a legitimate source with a legitimate LINK to its official website. It CAME into origin in the year 2000.

Right answer is (b) 2000

To explain I WOULD say: Email Phishing came into origin in the YEAR 2000 which is more tech-savvy. Here the email is created as if it has been sent from a LEGITIMATE SOURCE with a legitimate LINK to its official website.

Correct option is (a) Algo-based PHISHING

To explain: Phishing is a CATEGORY of social engineering attack. In ALGORITHM-Based Phishing, an algorithm for GENERATING random credit CARD numbers for getting an original card’s match.

Right CHOICE is (d) apps installed in the mobile

Easy explanation: Phishers often develop illegitimate websites for TRICKING users & FILLING their personal data such as bank account DETAILS, phone number, address, username, and passwords etc.

Right option is (c) 1990

Best EXPLANATION: ALGORITHM-Based Phishing was DEVELOPED in the year 1990 where the first team of phishers developed an algorithm for generating random credit card numbers for GETTING an original card’s match.

Right choice is (b) illegitimate

To EXPLAIN I would SAY: Phishing is a category of social engineering ATTACK that is used to steal user data. Phishers OFTEN DEVELOP illegitimate websites for tricking users & filling their personal data.

Correct ANSWER is (a) True

Explanation: At the time of DoS ATTACK, it becomes hard to manually filter or crash the traffic from such sources. DDoS are high traffic events that are measured in Gigabits PER second (Gbps) or packets per second (PPS).

The correct option is (a) Phishing attack

Best explanation: Phishing is an internet SCAM done by cyber-criminals where the user is convinced digitally to provide confidential INFORMATION. There are different types of phishing. Some of them redirect the user to different sites VIA EMAILS & SPYWARE.

The CORRECT answer is (a) True

For explanation I would say: A DoS ATTACK is very dangerous for any targeted VICTIM because it can seize business and bring LOSS to a company running on the website. A DDoS with 20 to 40 Gbps is enough for totally shutting down the MAJORITY network infrastructures.

Right answer is (b) HTTP Flooding

The BEST explanation: Network LAYER DoS attack is set up to congest the “pipelines” that are connecting user’s network. This INCLUDES attacks such as NTP amplification, SYN flooding, UDP flooding and DNS amplification.

Correct choice is (C) TCP FLOODING

Easiest explanation: In application Layer DoS, its threats to overload a server as it sends a large QUANTITY of requests REQUIRING resources for handling & processing. This category includes HTTP flooding, slow-flooding attack and DNS query flooding.

The CORRECT answer is (a) Layer3-4 DOS attack

Best explanation: Denial of Service attack becomes dangerous because it floods the target service over the INTERNET. There are two types of DoS attack. The Network Layer DoS is also known as the Layer 3-4 DoS attack.

Correct answer is (d) APPLICATION LAYER DoS

The best I can explain: DoS attacks are of two TYPES. These are Application Layer Attacks and Network Layer DoS attacks. Application Layer DoS is a type of DoS threats to overload a server as it sends a large number of REQUESTS requiring resources for handling & processing.

The correct option is (a) 2

To elaborate: With the help of DOS attack attackers try to busy its USERS by flooding the URL of the victim with limitless requests. There are TWO types of DoS attack. These are Application Layer Attacks and Network Layer DoS attacks.

Right choice is (c) DDoS attack

For explanation I would SAY: DDoS is another leading attack type. Instead of implementing single computer & its INTERNET bandwidth, a DDoS utilizes various systems & their connections for flooding the targeted WEBSITE.

Right OPTION is (B) Distributed Denial of SERVICE

For explanation I would say: When a DoS attack comes from a large number of IP addresses, this makes it HARD to manually filter or crash the traffic from such sources and the attack is known as a Distributed Denial of Service (DDOS) attack.

The correct option is (d) DDoS attack

The best I can explain: A DoS attack coming from a LARGE number of IP addresses, making it hard to MANUALLY filter or crash the TRAFFIC from such sources is known as a DISTRIBUTED Denial of SERVICE (DDoS) attack.

The CORRECT choice is (a) Denial of SERVICE

Explanation: A Denial of Service attack targets its victim by flooding the URL of the victim with unlimited requests. The INTENT of this attack is to overkill the targeted SERVER’s bandwidth and other RESOURCES of the target website.

Right choice is (c) website

To elaborate: Using of DoS attack put TOGETHER web RESOURCE by flooding its USERS with unlimited requests. During a DoS attack, the regular TRAFFIC on the target website will be either dawdling down or entirely interrupted.

Correct CHOICE is (a) data

The BEST I can explain: VPNs allow its USERS to attach to the internet VIA a remote or virtual server which preserves privacy. The data transferred between your device & the server is securely encrypted if you are using VPNs.

Correct answer is (B) VPNs

The explanation is: There is a suitable solution for PRESERVING privacy is by USING privacy-focussed SEARCH engines, and by using VPNs. VPNs allow its users to ATTACH to the internet via a remote or virtual server which preserves privacy.
