As cyber threats continue to grow in scale and sophistication, multi-factor authentication becomes even more crucial for modern organizations. Fortunately, there are numerous MFA solutions on the market, which guarantees that all businesses will find a tool that meets their expectations.
In this article, we'll break down the fundamentals of multi-factor authentication and hand-pick the best MFA tools to boost your business security.
Part 1. The Fundamentals of Multi-Factor Authentication Software
What is MFA?
Before exploring the different multi-factor authentication solutions, we must first define this practice.
Definition
MFA is a security mechanism that requires users to verify their identity using two or more separate credentials that are unique to them. Instead of relying solely on a single password, MFA utilizes multiple layers of security to ensure that only authorized users can access sensitive data.
The need for multi-factor authentication stems from the fact that passwords have proven insufficient against data breaches and unauthorized access. Cybercriminals and hackers often exploit weak or reused passwords to obtain users' sensitive information. MFA providers can successfully prevent this by introducing an additional step that confirms a user's identity.
How MFA Works
MFA works by requiring two or more verification factors. These factors are unique to the user, thus authenticating their identity. In more detail, multi-factor authentication can utilize:
- Something you know, such as a password or a PIN,
- Something you have, such as a smartphone or security token,
- Something you are, such as your biometric data (fingerprints or facial recognition).
The MFA solutions will check the input and grant access only when they detect the correct combination of these factors. For example, logging into a banking app from a new device might require a user to enter a password and then confirm a push notification on their registered mobile device or enter an OTP they receive.
Why MFA Is Critical for Cybersecurity
Multi-factor authentication solutions are more relevant than ever before as cyber threats have increased significantly. On top of that, they have become more sophisticated and targeted, meaning that hackers can now obtain what they need with ease. According to industry reports, more than half of data breaches are the direct effect of stolen credentials.
MFA can become the decisive factor in stopping these attacks as it makes it exponentially more difficult for hackers to gain control over user accounts. By implementing this mechanism, your business not only takes important steps towards the protection of your customers' data but also shows your commitment and trustworthiness.
Part 2. Types of Multi-Factor Authentication Solutions
As we've already mentioned, a multi-factor authentication software will utilize two or more separate factors to ensure the users' identity. Understanding the three primary types of authentication factors is the first step toward understanding MFA in general. These types are the following:
#1 Knowledge Factors (Something You Know)
These factors are something that the user already knows. They include passwords, PINs, and answers to security or secret questions. This is the type that you will find most frequently used. However, it is the weakest one since it can be guessed or stolen by experienced hackers.
#2 Possession Factors (Something You Have)
Another type of MFA is something that the user possesses. This could be a mobile phone, hardware tokens like RSA SecurID, or smart cards . For instance, a user might receive an OTP on their mobile device if they are trying to access a website or app from a new device. These factors add a physical element to the authentication process, which makes it harder for cyber-attackers to breach systems.
#3 Inherence Factors (Something You Are)
The final type of MFA uses the unique characteristics of a user. These include biometric verification data, such as fingerprints, retina scans, voice recognition, or face recognition. Since biometric traits are unique and difficult to replicate, these factors provide the strongest possible security layer.
Part 3. Choosing the Right MFA Solutions
There is no denying that MFA is a necessity for all businesses. But how do you make the right choice? In this section, we are going to dissect this decision into the key criteria, industry-specific needs, and questions you need to ask.
Key Criteria for Selecting MFA Solutions
When evaluating MFA tools, it is important to keep in mind certain criteria. These ensure that the software you select is the one that will satisfy your needs. The key criteria that you should consider are the following:
- User Experience: The solution should be intuitive and easy for both your team and your customers to use.
- Integration Capabilities: The tool should be compatible with the applications you are already using so that it doesn't disrupt your workflow.
- Scalability: The solution must support growth in the user base, a thing that is crucial for startups and fast-growing businesses.
- Cost-Effectiveness: You should always take into consideration the pricing of each tool as you want to allocate your budget most optimally.
Industry-Specific Needs in Multi-Factor Authentication Software
A decisive factor for selecting among the MFA providers is to consider what your industry commands. More specifically, here are the MFA needs of some sensitive industries:
- Finance: Requires strong regulatory compliance, such as PSD2 and SOX. In this industry, the focus is on biometric and possession factors that enhance the security of transactions.
- Healthcare: Must comply with HIPAA and HITECH standards. The MFA solutions aim to protect patient records and limit access to authorized personnel.
- Retail& E-commerce: In these industries, MFA helps prevent account takeovers and fraudulent transactions. Many businesses in the sectors utilize OTPs and security questions.
Key Questions to Ask MFA Providers
Ultimately, the decision should be tailored to your company's needs. Before you make it final, though, ask yourself and the MFA tool these questions:
- What authentication factors does your solution support?
- How is user identity verified and managed across devices?
- Can your solution scale globally and support remote workers?
- How is MFA integrated with existing identity and access management tools?
- What compliance standards does your product meet?
- How does your MFA handle device loss or recovery?
