To adapt to the global pandemic and continue to operate while complying with government guidelines, many companies have turned to working from home. In doing so, a tremendous amount of information is now exchanged online. That’s why it’s essential to be aware of the IT security issues involved in teleworking<\/a>, and to strengthen corporate cybersecurity<\/a>.<\/p>\n

Unfortunately, many organizations are not aware that their business communications are not secure enough. Many still rely on standard security procedures requiring only a simple username or password, which are no longer sufficient to guarantee the confidentiality of online exchanges. They are therefore vulnerable to theft of confidential information and sensitive data by cybercriminals.<\/p>\n

For a better level of corporate communications protection, new user identification strategies have therefore been developed. Among these, two-factor authentication is undoubtedly one of the most effective and easy to implement.<\/p>\n

In this article, our cybersecurity specialists explain this computer protection measure and how it is useful for companies that allow working from home.<\/p>\n

What is two-factor authentication?<\/h2>\n

Two-factor authentication, also called\u00a02FA, is a secure computer access process in which the user must provide two pieces of evidence in order to be authorized to access a program, feature or file.<\/p>\n

This strategy therefore provides a higher level of protection than single-factor authentication (SFA) methods, where the user only has to provide a single piece of information, such as a password or access code.<\/p>\n

Different types of identification factors that may be required during an access request<\/h3>\n

There are several types of identification factors that may be requested during an access attempt. This creates unique combinations that cybercriminals cannot duplicate.<\/p>\n

Knowledge factors<\/h4>\n

This is information that only the user should know. Passwords and personal identification numbers (PINs) fall into this category.<\/p>\n

Possession factors<\/h4>\n

This is an object that the user should have with them at the time of the access request. It may be a magnetic token or a security card, for example.<\/p>\n

Biometric authentication<\/h4>\n

This identification factor relies on the fact that each user has unique physical characteristics such as fingerprints or retina shape. Facial recognition is based on biometric factors.<\/p>\n

Location verification<\/h4>\n

Location verification requires the user to be in a particular location. The user will not be able to log in if they are outside the geographic area where they should be. The origin of an access request can be known based on geolocation information such as an IP address.<\/p>\n
