Which of the following is an example of a problem that could be attributed to poor ergonomics?

I would say B because Carpal tunnel syndrome is caused by repetitive flexing and extending of tendons (it gets worse if it's for a long time) pressure on the median nerve can cause pain numbness and weakness in the hand and wrist. So this is the best answer as it shows there is a poor working environment it would be better if there was something as simple as a mouse pad that the wrist could lay on while using the mouse for example or using padding on the desk could improve the working environment and prevent this.

Host Y sends the first TCP ACK message for the transaction?<br><br> a. true<br><br> b. false

kupik [55]

Answer: True

Explanation:

TCP is the transmission control protocol which and TCP ACK is the transmission control handshake method which are used by TCP. It basically indicates the next sequence number in the method when the flag is set.

Firstly, the ACK (Acknowledge) send by the each end for the initial sequence number itself but it does not contained any type of data. In the TCP segment header ACK contain 32 bit field.

The acknowledgement is just a proof to clients that ACK is a specific to the SYN when the clients initiate.

Your boss wants you to configure his laptop so that he can access the company network when he is on the road. You suggest a VPN

Rashid [163]

Answer:

All traffic that flows between the laptop and VPN server is encrypted.

Explanation:

A Virtual Private Network (VPN) is a "tunnel" connection between computers that performs just like a regular point-to-point network connection (that is, IP address to IP address). It has the added feature that encryption is enabled so that no intermediate server (or computer or line monitor, etc.) can decode the information that is in the data portion of the packets.

A company is executing a strategy to encrypt and sign all proprietary data in transit. The company recently deployed PKI service

Softa [21]

Answer:

A. S/MIME

B. TLS

C. Kerberos

Explanation:

PKI : Public Key Infrastructure is a technique which will allow services or applications to communicate securely across the unsecured network or internet.

PKI mainly consist of CA or Certificate Authority who can issue digital certificates or they are also known as trusted CA. exmaples are godaddy, digicert, verizone, symmantec, etc.. and RA also known as Registration Authorities and they verify if the requested certificates can be stored at CA. Keys will be stored in the central directory.It will also consists of certificate management system and the policies governing PKI.

S/MIME : Secure/Multipurpose Internet Mail Extensions which use assymentric cryptography and sign the MIME data. S/MIME will provide services like Authentication, Encryption , Integrity, Privacy and Non repudiation for messaging applications

SMIME uses certificates which can be self signed or CA certified. It specifies MIME type as $application/pkcs7-mime$ while transmitting the data.

TLS : Transport Layer Security. the earlier versions used to be known as SSL ( Secure Socket Layer) SSLv3 got depreciated and TLSv1.2/1.3 are popularly used to provide encryption, authentication, Integrity and Hashing for client to server side communication.

Most of the applications communicate securely using TLS. They will establish secure TCP connection using SSL Handshake. During the Handshake they will exchange supported versions, ciphersuites and certificates. Applications which uses TLS always uses CA certificates and Inhouse applications can communicate using self signed certificate or even with CA certificates.

HTTPS which is also known as HTTP over SSL is widely used for almost all the web services to communicate securely across the internet.

Kerberos : It is a protocol used to prove the identity for two nodes which are communicating with each other. Kerberos uses both symmetric key cryptography and assymetric key cryptography. However, symmetric key cryptography is used widely and public key cryptography is used optionally.

Authentication server which is also known as AS is used to authenticate the requesting client. It further forwards the user credentials to key distribution center. KDC further issues to TGT ( ticket granting ticket) and it uses TGS's secret key to encrypt. User will receive a encrypted output.

When a User Login then The client authenticates itself to the Authentication Server (AS) which forwards the username to a key distribution center (KDC). The KDC issues a ticket-granting ticket (TGT), which is time stamped and encrypts it using the ticket-granting service's (TGS) secret key and returns the encrypted result to the user's workstation. Sessions will be renewed and managed by users session manager.
