Top 11 Best Single Sign On Software (SSO) Vendors

Authentication is a process of identifying an individual or user on the basis of username and passwords, security tokens, biometrics which he or she claim to be but does not give any information about the access rights of the particular user. In the security systems authentication is well-defined from authorization, as it is the process in which the user is given complete access to the system objects based on their identity. The process is based on measure of the risk. Stronger Authentication is something the where high risk systems, applications and information needs different kinds of Authentication which accurately confirms the digital identity of the user who they claim to be, than the low risk application, where the confirmation of the digital identity of the individual is not that important when considering the risk factor.

Authentication process is mainly dependent on the identity verification and registration processes. For instance we take the example when Rachel Wiz has been hired by an employer and then she has to provide the personal information such as name, address, birth certificate, driving licence, SSN No, Passport details etc. Now it is up to the employer to accept it immediately or choose for a background check on the information provided by Rachel Wiz which she claims to be, they can also clarify whether she is having any criminal record. Once the check is completed and the results come in favour of the employer then they will confirm the identity as true and enter her details in their system. The identity process involves issuing Rachel with the employer authentication mechanisms which include passwords, digital certificates, id, security tokens and registering her biometrics.

Authentication process is purely dependent on the identity validation and the registration process used by Rachel Wiz. Think that Rachel has provided false information while the registration and which has been accepted by the employer, then the individual or user who is acting as Rachel will be always authenticated in the right perspective every single time. From this we understand that authentication is solely dependent on the information provided by the user which can be true or false, this shows the weaker side of the application.

Single Sign On Authentication

Single Sign-On (SSO) is an application where the user’s single action can authenticate, authorize and allow the user to access all the computers and systems where the user has the permission to access, without entering multiple passwords for every single login. Single Sign-On Software can regulate the components of system failures and reduce the number errors caused my humans, which is why the software is highly recommended globally. The Software is tested in different platforms of the industry from financial, clinical and administrative applications. Single Sign-On is a powerful application and can be enabled very fast which means the user can save more time.

In the Single Sign-On system the user logs with his user ID and password in the given fields and gets access to relatively low risk information and also can access to enterprise portals. The Single Sign On Software requires stronger authentication when the user is accessing to high risk information applications such as payroll management system, which includes security tokens, digital certificates, biometrics and smart cards.

Single Sign On can also occur in between two enterprises using organized authentication. In this case we can consider the example as, an employee of the business partner can log into their organizations system, when he or she clicks on the link provided by the enterprise application, then the Single Sign-On Software vendor will provide a security to the enterprise with the help of some of the protocols like Liberty Alliance, WS Federation, SAML etc. Single Sign-On Software of the enterprises then receives the security token and checks it thoroughly and it gives access to the employee without any sign in.

Single Sign-On Software should check every single request by the user’s browser to see is there an authentication policy referring to the application to which the user is trying to access. Whenever a user clicks on a URL in medium or larger enterprises there is traffic between the user’s browser and the security server, there every chance that this traffic can increase from the point of performance. In this scenario most of the SSO Solutions use directories like Light Weight Directory Protocol (LDAP) to store the authorization and authentication policies. These directories are meant for high performance, which can manage heavy traffic load. LDAP are often considered as a better resource for a SSO system against authentication.

In the small and medium enterprises, the enterprises can become single point of failure, if the Single Sign On application is not designed properly. No user can access any application protected by the Single Sign-On Software if the system goes down and the application or resource remains up. This uncertainty in the SSO results in productivity loss to the enterprises. Hence every enterprise whether it is large or medium should make sure that they a well-tested failover and disaster recovery design Single Sign-On system.

Whether it is small or medium enterprises it requires high standard identity data governance. All enterprises should have good and quick business process which can match with any changes such as identify termination, role changes, new identity creation etc. if the these changes are not practiced by the enterprises then their SSO application can be easily accessible and open to threats.

Password Authentication

We all live in the world of technology where everything issecurely unsecured where the user identity is not secured. There is every chance that a stranger can get access your to user data and steal the confidential information in not time, if the Password Authentication is not properly authenticated. Even though it is the weakest form of Authentication most of the Enterprises still relay on the same old user Password Authentication. Enterprises put every effort to strengthen the password but they could match up to the modern hackers.

A hardware keyboard logger was the first tool used to attack against password authentication, which are legally available online to buy at $40 and these are devices connected to the keyboard and computer. The hardware keyboard logger records each and every keystroke with some model which enables to date stamps and time against the data. The hardware keyboard logger is similar to a small piece of hardware that is connected to the computer and which takes only 10 seconds to install and which cannot be detected by any means of software’s available in the market.

Hackers have come up with new ways to hack the user passwords which further weakened the usage of password authentication. The password authentication logging software programs are embedded in the email which are activated by clicking on the links provided in the emails or by accessing a fake website which in all means looks like a regular website.

A group of well-organized web hackers have developed the software called keyboard logging software which will recognize the authentication passwords and user bank id, that the user enters logon to the banks website for transaction. Once these details are entered by the user the next second user id and password are sent to the organized crime servers, then the received user details are auctioned online to other web criminals and in no time users bank account will be emptied.

Use Single Sign On Software services to avoid these kind of criminal activities and be safe and protected all the time. Some precautions have to be followed by the user to strengthen the password like layered identity defence strategy, which means your enterprise will allow the use of user id and password to gain only general access to very low risk enterprise application and information for example the enterprises website. But when the user is trying to access applications which are higher risk then the enterprise should require stronger password authentication. In the process you should include the usage of digital certificates, smart cards, biometrics and security tokens.
