How the Two Factor Authentication Mobile Tehchnology has Evolved into a More secure System

In the past year or so, the adoption of two factor authentication mobile technology has been rapid. Many organizations in the healthcare, banking sector and even social media sites such as Facebook and Twitter have adopted this technology. This is a vote of confidence in the technology and its versatility, which previously was complicated to implement.

New Technology

The introduction of the mobile phone made it possible to get rid of the plastic tokens that were often sent to customers. The solution allowed for faster deployment of the system without the need for an extra token. However, the infrastructure needed improvements for both the smart phone and the ordinary cell phone.

Improved Security

The first step that engineers worked on was a more secure system, which was not vulnerable to DoS or man in the middle attacks. The new systems work on sending the secret code through a different network, such as the GSM network, which makes the system harder for hackers to attack.

Smartphone and SMS Technology

The two factor authentication mobile technology can be implemented though the smart phone. The smart phone provides a higher data capacity than the ordinary phone. An app installed on the phone helps to implement a sophisticated system that is more secure.

The other thing that was done when trying to make the Secure 2 factor authentication service more secure was to implement a onetime SMS code that had a rotational mechanism, which ensured that the codes were not compromised, incase hackers could get their hands on them. Many solutions also back up the codes in case the devices get lost.

As all these improvements are made to the existing Secure 2 factor authentication service, there is the risk of making it cumbersome and complex. A good system should also be easy to use, otherwise users will find be reluctant to adopt it.


How to Ensure the SMS 2 Factor Authentication is Adopted and Accepted by its Users

If you are dealing with sensitive information in your organization, then implementing a secure 2 factor authentication system is one of the steps you ought to take. Passwords are hardly effective on their own, as users often pick passwords that are vulnerable to dictionary attacks. Implementing this system may prove challenging when it comes to adoption by its users.

Consider the User’s Attitude

One of the problems you may encounter is the transition to a system that requires keying in information. Many users may already be used to either logging the system without keying in passwords or only adding one or two digits into a text box.

The infrastructure used for this form of cloud authentication can be implemented in several ways. One way is to require that the 2FA be only applied for remote workers. Remote workers provide a higher level of risk and are vulnerable to all manner of attacks, though the organizations wireless system.

Limiting its Application

The system may also be implemented by requiring that only the most vulnerable groups such as remote workers and people using the Virtual Private Networks be required to use this form of authentication. The workers on site should however be screened as they go from one room to another.

More Possibilities

SMS provide an out of network secure channel for delivering the codes. However, the Smartphone provides more possibilities than SMS 2 Factor authentication, particularly if you are looking to enable the users to avoid keying in a lot of information. Image codes may be entered though simply touching the screen.

 How well the system is adopted by the user will depend mainly on its design, against what the user is used to. A good system should not burden the user with codes, particularly if the resources they are trying to access are not vulnerable to attacks. Therefore the key to the adoption of the cloud authentication system lies in its design.

What Makes a Strong SMS 2 Factor Authentication

In the past two years or so, the cloud authentication service has blown up. Big online companies like Google, Twitter and even Facebook have offered this extra layer of security to help its users feel more secure. Even though these two levels of authentication have been around since the late 90s, there is a reason why it became popular in the last two years.

The SMS Factor

SMS 2 factor authentication became popular because more people own a mobile phone now more than ever. Mobile phones have become ubiquitous both in the developed world and in the third world. However, there is a difference between a strong secure system and one that is not.

A strong cloud authentication system will have a good implementation of a one time password or code. This code ought to expire within a fixed period of time. The code is received through text messaging to the recipient’s mobile phone and he has to respond within a specified period of time before the code expires.

Expiring Codes

The fact that the code expires means that it will not allow hackers time to do a search on codes. The strong cloud authentication system will reject a code that is entered after that period and therefore limits the time that hackers will have to go through different codes.

Code Encryption

For the system to be stronger, the code has to be encrypted. Many hackers will use Trojan horses and other malware to send information to their servers. If the code is not encrypted they will simply have an easy time getting through to the account.

A highly encrypted SMS 2 factor authentication combined with an expiring code, can give a very high level of security to the organization, whether it is a bank or an IT organization. This is one of the most reliable and cost effective systems that is going to define the future of internet security.
