Question 1

Which of the following is a non-technical type of intrusion or attack technique?
A)reverse engineering
B)malware analysis
C)social engineering
D)malware writing

Social engineering is a non-technical method that relies on human interaction to gain unauthorized access to information or systems. It manipulates individuals into breaking normal security procedures.

Question 2

If the data stored in the_______ is not encrypted, then after cookie stealing, attackers can see information such as username and password stored by the cookie.
A)memory
B)quarantine
C)cookies
D)hard drive

Accepted Answer

Cookies are used to store user data for web sessions, and if they are not encrypted, attackers can access sensitive information like usernames and passwords through cookie stealing.

Question 3

The stored cookie which contains all your personal data about that website can be stolen away by________using or trojans.
A)attackers, malware
B)hackers, antivirus
C)penetration testers, malware
D)penetration testers, virus

Accepted Answer

Attackers can use malware or trojans to steal cookies containing personal data from a user's computer. Malware is a broad term that includes various malicious software, including trojans, designed to harm or exploit any programmable device, service, or network. Hackers are a more specific group that might engage in such activities, but the term "attackers" encompasses anyone who attempts to exploit vulnerabilities, including hackers. Antivirus is software designed to prevent, detect, and remove malware, not to steal cookies. Penetration testers are professionals who are hired to test and improve the security of a system, not to steal data or engage in malicious activities.

Question 4

If a website uses a cookie, or a browser contains the cookie, then every time you visit that website, the browser transfers the cookie to that website.

Accepted Answer

Cookies are designed to be sent back to the server each time the user visits the website that set the cookie, allowing the server to recognize the user's browser and retain information about the user's preferences or past actions.

Question 5

Which of them is not a proper method for email security?
A)use strong password
B)use email encryption
C)spam filters and malware scanners
D)click on unknown links to explore

Accepted Answer

Clicking on unknown links to explore is not a proper method for email security. It can lead to phishing attacks, malware infections, and other security breaches.

Question 6

What are email security services?
A)confidentiality
B)authentication
C)non-repudation of origin
D)all of the above

Accepted Answer

Email security services encompass a range of measures designed to secure the access and content of an email account or service. This includes ensuring the confidentiality of messages, verifying the identity of senders and recipients (authentication), and providing proof of the origin of messages that cannot be disputed (non-repudiation of origin). Therefore, all the options listed contribute to the overall concept of email security.

Question 7

PGP security system uses
A)public key cryptosystem
B)private key cryptosystem
C)public & private key cryptosystem
D)none of the mentioned

Accepted Answer

PGP (Pretty Good Privacy) uses a combination of public and private key cryptosystems for secure communication. It encrypts data using a public key and decrypts it with a private key, and vice versa for digital signatures.

Question 8

What is the key size allowed in PGP?
A)1024-1056
B)1024-4056
C)1024-4096
D)1024-2048

Accepted Answer

PGP (Pretty Good Privacy) allows for a key size range of 1024 to 4096 bits, offering flexibility in the level of security and computational requirements for encryption and decryption processes.

Question 9

Who created PGP?
A)phil zimmermann
B)tim berners-lee
C)marc andreessen
D)ken thompson

Accepted Answer

Phil Zimmermann is the creator of Pretty Good Privacy (PGP), a data encryption and decryption program that provides cryptographic privacy and authentication for data communication.

Question 10

What is the PGP stand for?
A)permuted gap permission
B)permuted great privacy
C)pretty good privacy
D)none of the mentioned

Accepted Answer

PGP stands for Pretty Good Privacy, which is a data encryption and decryption computer program that provides cryptographic privacy and authentication for data communication.

Question 11

PGP makes use of which cryptographic algorithm?
A)des
B)aes
C)rsa
D)rabin

Accepted Answer

PGP (Pretty Good Privacy) primarily uses RSA for encrypting session keys and for digital signatures.

Question 12

PGP offers_______block ciphers for message encryption?
A)triple-des
B)cast
C)idea
D)all of the above

Accepted Answer

PGP (Pretty Good Privacy) supports multiple block ciphers for message encryption, including Triple-DES, CAST, and IDEA, hence the correct choice is "all of the above."

Question 13

S/MIME stands for________ .
A)standard multipurpose internet mail extensions.
B)secure multipurpose internet mail extensions.
C)secure multipurpose international mail extensions
D)standard multipurpose international mail extensions.

Accepted Answer

S/MIME stands for Secure Multipurpose Internet Mail Extensions, which is a standard for public key encryption and signing of MIME data.

Question 14

is used for hiding the payment information from the merchant.
A)set.
B)ssl.
C)shttp
D)tsp

Accepted Answer

SET (Secure Electronic Transaction) is a protocol used to secure credit card transactions over the internet by hiding payment information from the merchant.

Question 15

The cryptography algorithms used in S/MIME are .
A)idea.
B)rc4
C)rsa,des-3
D)rc5

Accepted Answer

S/MIME (Secure/Multipurpose Internet Mail Extensions) uses various encryption algorithms to secure email communications. Among the options given, RSA (Rivest-Shamir-Adleman) is widely used for encrypting the keys that are then used to encrypt the email content. DES-3 (Triple Data Encryption Standard) is another algorithm used for encrypting the actual email content. IDEA, RC4, and RC5 are encryption algorithms but are not specifically tied to the S/MIME standards for email encryption.

Question 16

In S/MIME,MLA stands for .
A)mailing list agent.
B)multipurpose list agent.
