SSL/TLS and HTTPS MCQs

SSL stands for Secure Socket Layer, a standard technology for establishing an encrypted link between a web server and a browser.

The primary purpose of SSL/TLS is to encrypt data transmitted between a web server and a browser, ensuring data privacy and security.

SMTP (Simple Mail Transfer Protocol) is typically used for securing email communication using SSL/TLS.

The primary purpose of HTTPS is to encrypt data transmitted between a web server and a browser, enhancing data security.

The main advantage of using HTTPS over HTTP is encrypted data transmission, ensuring data privacy and security.

Certificate Authorities (CAs) are responsible for issuing and validating SSL/TLS certificates for websites.

RSA encryption is commonly used in SSL/TLS to secure data transmission, specifically for key exchange.

TLS stands for Transport Layer Security, the successor to SSL for securing data transmission.

Port 443 is commonly associated with HTTPS traffic, which uses SSL/TLS encryption.

Self-signed SSL certificates may trigger security warnings in browsers because they are not issued by trusted CAs.

A Certificate Signing Request (CSR) is used to request a signed SSL/TLS certificate from a Certificate Authority.

AES encryption is commonly used in SSL/TLS for securing data transmission, providing strong encryption.

The "Common Name" (CN) field in an SSL/TLS certificate is used to specify the server's domain name.

The "Issuer" field in an SSL/TLS certificate identifies the Certificate Authority (CA) that issued the certificate.

Diffie-Hellman key exchange is commonly used in SSL/TLS for securing data transmission.

A Wildcard SSL/TLS certificate is primarily used for securing multiple subdomains of a single domain.

The "Strict-Transport-Security" header can be used to indicate the desire for an HTTPS connection in a web request.

SHA-256 is commonly used in SSL/TLS for certificate signatures due to its strength and security.

Certificate chaining in SSL/TLS creates a chain of trust from the end-entity certificate to a trusted root certificate.

The "Extended Validation" (EV) SSL/TLS certificate provides the highest level of validation and trust for websites.

The HTTP status code 301 (Moved Permanently) is commonly used to indicate that a web resource has permanently moved to a new location (URL).

The Internet Engineering Task Force (IETF) is responsible for maintaining the X.509 standard, which defines the format of SSL/TLS certificates.

The "Subject Alternative Name" (SAN) field in an SSL/TLS certificate is used to list additional domain names that the certificate is valid for.

The "Strict-Transport-Security" header instructs the browser to upgrade an HTTP connection to HTTPS, enhancing security.

The Root Certificate is used to verify the authenticity of end-entity certificates in SSL/TLS, creating a chain of trust.

The "Key Usage" extension in an SSL/TLS certificate defines the purposes for which the certificate's public key can be used.

SSL/TLS provides data confidentiality, data integrity, and authentication, but it does not directly provide data availability.

The Public Key Infrastructure (PKI) in SSL/TLS is responsible for managing the trust and distribution of public keys, including SSL/TLS certificates.

Certificate Revocation List (CRL) is a protocol used for securely revoking SSL/TLS certificates.

The main goal of SSL/TLS in data transmission is to ensure data privacy and security through encryption.

Diffie-Hellman is a commonly used cryptographic protocol in SSL/TLS for secure key exchange.

The Certificate Revocation List (CRL) is used to securely revoke SSL/TLS certificates when necessary.

The "X-Frame-Options" header can be used to prevent a web page from being displayed within an iframe, enhancing security.

A SAN SSL/TLS certificate is primarily used for securing multiple subdomains of a single domain.

The "Organizational Unit" (OU) field in an SSL/TLS certificate provides information about the organizational unit or department.

The "Access-Control-Allow-Origin" header is used to specify which domains are allowed to embed a web resource using iframe.

The "Common Name" (CN) field in an SSL/TLS certificate is used to specify the server's domain name.

MD5 is considered insecure and should be avoided in SSL/TLS due to vulnerabilities.

The "Extended Validation" (EV) SSL/TLS certificate provides the highest level of validation and trust for websites.

The Intermediate Certificate bridges the trust between the end-entity certificate and the Root Certificate in SSL/TLS.

The "Access-Control-Allow-Origin" header is used to control which domains are allowed to make requests to a web resource.

The "Basic Constraints" extension in an SSL/TLS certificate indicates whether the certificate can sign other certificates, allowing it to act as a Certificate Authority (CA).

The Internet Engineering Task Force (IETF) is responsible for the development and maintenance of the SSL/TLS protocols.

The Private Key is used in SSL/TLS to decrypt encrypted data, ensuring data privacy.

The "X-Content-Type-Options" header can be used to specify the desired behavior when loading mixed content over HTTPS.

The Root Certificate represents the highest level of trust in the certificate chain and is used to verify the authenticity of other certificates.

In SSL/TLS, a session key is used for encryption to ensure data privacy.

The HTTP Strict-Transport-Security (HSTS) header enforces the use of HTTPS on a website, instructing the browser to only use secure connections.

Transport Layer Security (TLS) is commonly used for securing email communication, ensuring data privacy.

The Subject Alternative Name (SAN) extension is used to include additional domain names that the certificate is valid for, allowing a single certificate to secure multiple domains.
