A tax organization is working on a solution to validate the online submission of documents. The solution should be carried on a portable USB device that should be inserted on any computer that is transmitting a transaction securely. Which of the following is the BEST certificate for these requirements?
A computer certificate, also known as a machine certificate, is issued to a specific computer or device. In this scenario, the requirement is to securely validate transactions from any computer using a portable USB device. A computer certificate is suitable for authenticating the device itself when plugged into different computers. This ensures that the transactions are securely validated, irrespective of the user or computer, by verifying the identity of the device initiating the secure transaction.
I'm going to give details of what is the use of each one, because I'm tired that are not giving the right answer: User Certificate: User certificates specify which resources a given user can have access to. They are sometimes used on devices that several users share. When different users log in, their profile and certificate are automatically loaded, granting them access to their required information. Self-signed certificate: A self-signed certificate is one that is not signed by a CA at all – neither private nor public. In this case, the certificate is signed with its own private key, instead of requesting it from a public or a private CA (Certificate Authority). Root Certificate: Root certificates are the cornerstone of authentication and security in software and on the Internet. They're issued by a certified authority (CA) and, essentially, verify that the software/website owner is who they say they are. So for this verification I'm completely 100% sure is A: User certificate
You didn't mention anything about a computer certificate.
"Machine/computer A company may want to encrypt the communication between computers on the network. For example, a company may want to encrypt communication between its servers. In order to do this, each computer needs a machine certificate, also known as a computer certificate, applied to it." -Comptia Security+ Certification Fourth Edition SY0-601 by Glen Clarke & Dan Lachance "Machine/Computer. Certificates issued to a device or a computer are commonly called machine certificates or computer certificates. The certificate is typically used to identify the computer within a domain." -Security+ Get Certified Get Ahead SY0-601 by Darril Gibson "Machine/Computer. Assigning a certificate to individual computers isn’t too common, but there are places where this is used. Very high-security, enterprise-level 802.11 wireless networks using EAP-TTLS security can assign a machine certificate to every system." -Mike Meyers' Security+ Cert Guide Third Edition SY0-601
User certificates are bound to 1 user, and this solution is supposed to be for any computer uploading/transmitting, which means it has more than one user and thus cannot be a user certificate. Self-signed it is.
A self-signed certificate can be spoofed by literally any other computer and is not secure in the slightest. Self-signed it isn't.
It is C. computer certificate. User certificate doesnt make any sense when talking about using different computers
I though option A make sense - if acquired from a publicly trusted CA. Found this link below from IdenTrust about IRS Secure Data Transfer... https://www.identrust.com/partners/department-treasury-irs-secure-data-transfer
That is a user certificate (the requestor must provide their personal ID to obtain one).
I answered A. The question mentions that the solution is on "a portable USB" meaning a user would need to insert it into whichever PC they're transmitting transactions from. Not necessarily contained to one computer as some have stated.
At first I was thinking Computer certificates, but "portable" really is the key word here. So either a User certificate or a self signed could work. I'd go with a User's.
Just passed the exam thanks
root certificate is the foundation of a public key infrastructure (PKI). It is issued by a trusted certificate authority (CA) and serves as the starting point for validating other certificates. In this scenario, the tax organization can carry the root certificate on a USB device. When inserted into any computer, it ensures secure validation of online document submissions
Root Certificate: A root certificate is a digital certificate issued by a trusted Certificate Authority (CA). It is used to establish the authenticity of other certificates in a public key infrastructure (PKI) system. In this scenario, having a root certificate installed on the USB device allows it to validate the authenticity and trustworthiness of other certificates, such as server certificates used for secure transactions. Portable Validation: Since the USB device needs to validate transactions on any computer, having a root certificate ensures that it can establish trust with any server certificate presented during the transaction. Root certificates are widely recognized and trusted, allowing the USB device to securely validate transactions across different environments.
User Certificate: Used for individual user authentication in online interactions, often stored on portable devices like USB tokens.
I understand the question like this: the tax organization wants to validate online submissions of documents using a portable USB device. Which means EACH USER transmitting documents needs to be validated using ANY computer. This is why I am choosing A. User Certificate The user is authenticated with the USB device not the C. Computer Certificate (validates the computer but the scenario wants to use a USB device to validate users on any computer) Not with D. Root Certificate (validates software; scenario is asking to validate transmissions not the application). Not with B. Self-signed Certificate because is neither private or public, not signed by a CA, and in this scenario the organization is looking to validate ONLINE submissions; self-signed certificates can be spoofed.
The answer here is C. The solution is on the USB, meaning the certificate (computer certificate) and it has to trust other devices outside of the tax company. The question states that the USB can be inserted into "any computer" so that documents etc., can be transferred securely. It can not be self-signed certificate because it is not being used internally. The USB is going to different companies' devices outside of the tax company. Self signed only works if the company created certificate and is its own CA and wants its own devices to know its own self created certificate.
In my opinion the answer is A: User. Certificates can also be issued to users. They can be used for encryption, authentication, smart cards, and more. For example, Microsoft systems can create user certificates allowing the user to encrypt data using Encrypting File System (EFS) Self-signed. A self-signed certificate is not issued by a trusted CA. Private CAs within an enterprise often create self-signed certificates. They aren’t trusted by default. However, administrators can use automated means to place copies of the self-signed certificate into the trusted root CA store for enterprise computers. Self-signed certificates from private CAs eliminate the cost of purchasing certificates from public CAs.
It's a machine certificate validated by the USB device. You go to any computer, plug in the USB, and voila, it's validated. At any moment, it mentions the need for users to validate it. I'm sure in real life, you'll have additional controls, and some related to users. But that's not the focus here.
Answer is Computer Certificate digital certificate is a file or electronic password that proves the authenticity of a device, server, or user through the use of cryptography and the public key infrastructure (PKI).
A. User certificate
Computer Certificate: A computer certificate, also known as a machine certificate or host certificate, is issued to a specific computer or device. In this case, having a computer certificate on the portable USB device ensures that the device itself is authenticated when plugged into any computer. This type of certificate is suitable for validating the identity of the computer or device initiating a secure transaction.
A computer certificate is typically issued to a computer or device and is used to establish the identity of the device when connecting to a network or service securely
"A tax organization is working on a solution to validate the online submission of documents". Sounds like this organization is working on a solution internally Self-signed certificates appear to work for this scenario. Self-signed certificates are now primarily used for internal purposes, such as testing, development environments, or private networks, where the need for third-party validation is minimal. https://venafi.com/
User certificates are bound to 1 user, and this solution is supposed to be for any computer uploading/transmitting, which means it has more than one user and thus cannot be a user certificate. Ditto user certificates: "Computer Certificate Templates are intended to be bound to a single computer entity to provide identity and/ or encryption services for that computer" https://www.sciencedirect.com/topics/computer-science/computer-certificate Root certificate wouldn't apply as it comes from a certified authority (CA). Self-signed is referring to the USB being added to the computers which are currently uploading with various users/computers, so this is a separate thing from both.
