SSH (Secure Shell) Why is IPsec considered a transparent protocol?Why is IPsec considered to be a transparent security protocol? – IPsec is designed to not require modifications of programs, or additional training, or additional client setup. – IPsec uses the Transparent Encryption (TE) algorithm. What secure protocol is recommended for network address translation?IPsec is the secure protocol recommended for network address translation. Layer issue. A router is a device for the network layer, yet as a NAT device it is required to tamper with the transport layer in the form of port numbers. What cryptographic transport algorithm is considered to be significantly more secure than SSL?Although TLS v1.0 was considered marginally more secure than SSL v3. Is there a secure Telnet?Telnet is inherently insecure. Credential information (usernames and passwords) submitted through telnet is not encrypted and is therefore vulnerable to identity theft. However, users can establish an Secure Shell connection instead to prevent this type of intrusion How do I make Telnet more secure?You can configure your Telnet server to use the Secure Sockets Layer (SSL) to secure Telnet communications sessions. To configure your Telnet server to use SSL, you must use Digital Certificate Manager (DCM) to configure the certificate for the Telnet server to use. Which is more secure Telnet or SSH?As compared to SSH Telnet is less secured. Telnet transfers the data in simple plain text. On other hand SSH uses Encrypted format to send data and also uses a secure channel. No authentication or privileges are provided for user’s authentication. Which protocol and port is the more secure version of Telnet?SSH serves the same primary function as Telnet but does so in a more secure way. This protocol provides secure access even on unsecured networks, eliminating many of Telnet’s vulnerabilities. What are benefits of IPsec?Benefits of IPSec
What are the different features of IPsec?Key Features of IPSec VPN
What are the 3 function of IPsec?Three protocols may be used in an IPsec implementation: ESP, Encapsulating Security Payload. Encrypts and/or authenticates dataAH, Authentication Header In which two ways does IPsec protect communications?IPsec uses cryptographic security services to protect communications over Internet Protocol (IP) networks. It supports network-level peer authentication, data origin authentication, data integrity, data confidentiality (encryption), and replay protection. What secure protocol is recommended for network address?SSL A Secure Socket Layer (SSL) is a network security protocol primarily used for ensuring secure internet connections and protecting sensitive data. This protocol can allow for server/client communication as well as server/server communication. What secure protocol is recommended for time synchronization?Network Time Protocol (NTP) is one of the oldest Internet protocols in use. It enables the synchronization of clocks on computer networks to within a few milliseconds of standard universal coordinated time (UTC). It is a crucial component of Internet security. How does NAT provide security?NAT Security Because NAT transfers packets of data from public to private addresses, it also prevents anything else from accessing the private device. The router sorts the data to ensure everything goes to the right place, making it more difficult for unwanted data to get by. Which layer of the OSI model contains the TCP protocol which is used for establishing connections and reliable data transport between devices?The transport layer What common method is used to ensure the security and integrity of a root CA group of answer choices?What common method is used to ensure the security and integrity of a root CA? – Keep it in an offline state from the network. What type of cryptographic algorithm creates a unique digital fingerprint of a set of data?A hash algorithm creates a unique digital fingerprint of a set of data. This process is called hashing, and the resulting fingerprint is a digest (sometimes called a message digest or hash) that represents the contents. Hashing is used primarily for comparison purposes. What block cipher mode of operation uses the most basic approach where the plaintext is divided into blocks and each block is then encrypted separately?electronic codebook (ECB) mode What is the secure version of Telnet?SSH (Secure Shell) Why Telnet is not secured?Telnet is not a secure communication protocol because it does not use any security mechanism and transfers the data over network/internet in a plain-text form including the passwords and so any one can sniff the packets to get that important information. Does Telnet have encryption?The encryption in telnet is based upon a shared secret key, not a public/private key system. The shared secret is established with kerberos authentication. If you do not have valid kerberos tickets, you can not establish a secure and encrypted connection with our current telnet client or telnet server programs. Can you secure Telnet?Telnet is inherently insecure. Credential information (usernames and passwords) submitted through telnet is not encrypted and is therefore vulnerable to identity theft. However, users can establish an Secure Shell connection instead to prevent this type of intrusion Why is Telnet unsecure?The encryption in telnet is based upon a shared secret key, not a public/private key system. The shared secret is established with kerberos authentication. If you do not have valid kerberos tickets, you can not establish a secure and encrypted connection with our current telnet client or telnet server programs. What protocol is more secure Telnet or SSH Why?SSH is a more secure protocol, so it uses public-key encryption for authentication. Telnet transfers the data in plain text. The encrypted format should be used to send data and also uses a secure channel. Telnet is vulnerable to security attacks. Which cryptographic mechanism can enforce the non repudiation of an e mail and its content?Privacy Enhanced Mail (PEM) was an email encryption mechanism that provided authentication, integrity, confidentiality and nonrepudiation.
Why is IPsec considered to be a transparent security protocol quizlet?"Why is IPsec considered to be a transparent security protocol? - IPsec is designed to not require modifications of programs, or additional training, or additional client setup. - IPsec uses the Transparent Encryption (TE) algorithm."
Which protocol supports two encryption modes transport and tunnel?IPSec operates in two modes: Transport mode and Tunnel mode. You use transport mode for host-to-host communications. In transport mode, the data portion of the IP packet is encrypted, but the IP header is not. The security header is placed between the IP header and the IP payload.
What type of cryptographic algorithm creates a unique digital fingerprint of a set of data?A hash algorithm creates a unique "digital fingerprint" of a set of data. This process is called hashing, and the resulting fingerprint is a digest (sometimes called a message digest or hash) that represents the contents.
