Beware of questions that do not include explanations - many people have identified errors in these and even when there aren't errors, these types of questions encourage you to memorize answers instead of understanding the underlying concepts. * Don't you hate those little asterisks. Normally they mean "forget what you just read, it's not really true." Not so here though. The bank starts with 293 multiple choice practice test questions, but I'm still adding to them. There will be more. ** CompTIA identified five domains of objectives for the CompTIA Network+ exam. They are:
  • 1.0 Networking Architecture

Tokens or Key Fobs

A token or key fob (sometimes simply called a fob) is an electronic device about the size of a remote key for a car. You can easily carry them in a pocket or purse, or connect them to a key chain. They include liquid crystal display (LCD) that displays a number that changes periodically, such as every 60 seconds. To differentiate them from logical tokens, they are sometimes called hardware tokens.

The token is synced with a server that knows what the number is at any moment. For example, at 9:01, the number displayed on the token may be 135792 and the server knows the number is 135792. At 9:02, the displayed number changes to something else and the server also knows the new number.

This number is a one-time use, rolling password. It isn’t useful to attackers for very long, even if they can discover it. For example, a shoulder surfing attacker may be able to look over someone’s shoulder and read the number. However, the number expires within the next 60 seconds and is replaced by another one-time password.

Get Certified Get Ahead

Users often use tokens to authenticate via a web site. They enter the number displayed in the token along with their username and password. This provides dual-factor authentication because the user must have something (the token) and know something (their password).

RSA sells RSA Secure ID, a popular token used for authentication. You can Google “Secure ID picture” to view many pictures of these tokens. Although RSA tokens are popular, other brands are available.

USB tokens include a USB connector and a smart chip. The smart chip typically stores a certificate similar to how smart cards store a certificate. In addition to being used for authentication, the embedded certificate supports the use of digital signatures.

HMAC-based One-Time Passwords

HMAC-based One-Time Password (HOTP) is an open standard used for creating one-time passwords, similar to those used in tokens or key fobs. The algorithm combines a secret key and an incrementing counter, and then uses HMAC to create a hash of the result. It then converts the result into an HOTP value of six to eight digits.

Imagine Bart needs to use HOTP for authentication. He requests a new HOTP number using a token or a software application. He can then use this number for authentication along with some other authentication method, such as a username and password. As soon as he uses it, the number expires. No one else is able to use it, and Bart cannot use it again either.

Here’s an interesting twist, though. A password created with HOTP remains valid until it’s used. Suppose Bart requested the HOTP number but then got distracted and never used it. What happens now? Theoretically, it remains usable forever. This presents a risk related to HOTP because other people can use the password if they discover it.

FOR THE NEW PERFORMANCE BASED QUESTIONS 

Bonus - Performance Based Questions

Additional Security+ questions to help you prepare for the new performance based questions. These are included with the full bank of Security+ practice test questions and are divided into different sections. For example, you'll have access to the following links:

- Performance Based Question - Set 1

You'll see a graphic explaining what you might be required to do on the actual exam to match different types of security to mobile devices and servers in a data center. You'll then have two questions that test your knowledge and ability to correctly answer the questions. This question also includes a link to a graphic showing the end solution for the overall performance based question simulation.

- Performance Based Question - Set 2

You'll see a graphic explaining what you might be required to do on the actual exam to match different types of attacks with the name of the attack type. You'll then have five questions that test your knowledge and ability to correctly answer the questions. This question also includes a link to a graphic showing the end solution for the overall performance based question simulation.

- Performance Based Question - Set 3

You'll see a graphic showing a network with computers and servers separated by a firewall. The firewall is used to control traffic between the computers and users using rules within an access control list (ACL).  You'll have three questions that test your knowledge and ability to correctly identify the relevant components of the rule. The incorrect answers and explanation provide you with insight into how to correctly answer this type of question on the actual exam.

- Performance Based Question - Set 4

You'll see a graphic explaining what you might be required to do on the actual exam related to what a forensic analyst would do during an investigation.

Time-based One-Time Passwords

A Time-based One-Time Password (TOTP) is similar to HOTP, but it uses a timestamp instead of a counter. Moreover, one-time passwords created with TOTP expire after 30 seconds.

One significant benefit of HOTP and TOTP is price. Hardware tokens that use these open source standards are significantly less expensive than tokens that use proprietary algorithms. Additionally, many software applications use these algorithms and they are freely available.

For example, the following figure shows the free VIP Access app created by Symantec and running on an iPad. It’s also available for many other tablets and smartphones. Once you configure it to work with a compatible authentication server, it creates a steady stream of one-time use passwords. The six-digit security code is the password, and the counter lets you know how much more time you have before it changes again.

One-Time Passwords

VIP Access app

Similar to a hardware token, the user enters a username and password as the something you know factor, and then enters the security code from the app as the something you have factor. This provides dual-factor authentication. Many public web sites like eBay and PayPal support it, allowing many end users to implement dual-factor authentication as long as they have a smartphone or tablet device.

Remember this

HOTP and TOTP are both open source standards used to create one-time use passwords. HOTP creates a one-time use password that does not expire. TOTP creates a one-time password that expires after 30 seconds.


 

Q. Your organization is planning to implement remote access capabilities. Management wants strong authentication and wants to ensure that passwords expire after a predefined time interval. Which of the following choices BEST meets this requirement?

A. HOTP

B. TOTP

C. CAC

D. Kerberos

Answer is B. A Time-based One-Time Password (TOTP) meets this requirement. Passwords created with TOTP expire after 30 seconds.

HMAC-based One-Time Password (HOTP) creates passwords that do not expire.

A Common Access Card (CAC) is a type of smart card, but it does not create passwords.

Kerberos uses tickets instead of passwords.

See Chapter 1 of the CompTIA Security+: Get Certified Get Ahead: SY0-401 Study Guide for more information on authentication concepts.
