Multi-factor Authentication (MFA) is a process that makes the user provide verification to gain access to organizational resources. A security policy must have MFA as a basic component in order to identify the user before granting access. Using MFA is a competent way to ensure authorized access when working with vendors.

Recent forecasts have shown that the market size for the global MFA market is expected to cross $26 billion by 2027. MFA solutions are becoming popular as they help businesses limit unauthorized access and ensure data protection. However, prior to deploying such solutions, organizations must first understand their significance with regard to vendor access.

Unraveling the Basics of Multi-factor Authentication

MFA provides an additional layer of safety and helps prevent unauthorized access to company accounts and databases. These solutions basically require the user to go through a series of authorization protocols if any anomalies with the access request are detected. MFA authentication works based on different factors that include:

• Knowledge factors – require the user to provide passwords, personal identification numbers (PINs), and answers to security questions.
• Possession factors – require users to authenticate their identities based on possessions such as a one-time password (OTP) or a security code.
• Inherence factors – require users to verify their identities using retain or fingerprint scan and is often the most sophisticated authentication method.

Why MFA is Crucial for Vendor Access Security

MFA is a cybersecurity measure that usually requires two or more types of factors or components when logging into a system. Businesses, when working with vendors, should not rely on usernames and passwords alone. A threat actor who exploits network vulnerabilities can comprise login credentials from a vendor’s system.

They can then use these details to gain access to a business’s network. An increasing number of cyber incidents requires that MFA must be in place as a base requirement. It is important because it adds an extra layer of authentication, ensuring that cyber criminals are non able to gain unauthorized access if vendor credentials are compromised.

Different Types of Authentication Factors in MFA

MFA is a critical component of a vendor access management solution. Therefore, it’s essential for organizations to understand the different types of authentication protocols that MFA uses. These protocols include:

Security Questions

This is one of the most basic forms of MFA authentication and requires the user to provide answers to one or more predefined questions. This protocol is triggered when anomalies with an access request are detected and is used to verify the user’s identity.

OTPs

An OTP, also known as a one-time PIN or one-time authorization code (OTAC), is a password that one can use if their login credentials have been compromised. OTPs avoid several shortcomings that are associated with traditional password-based authentication as they are sent only to those with an approved device.

Biometrics

It refers to a cybersecurity authentication process verifying a user’s authorization and access request using their unique biological traits. The basic types of biometric identifiers include fingerprints, voices, retina, or facial scans.

QR Codes

QR code, also known as quick-response code, is a type of two-dimensional matrix barcode used for granting access. These codes are often used by authentication applications where a user is required to use their smartphone camera to scan a code for the purpose of verifying their identity.

The Implementation Process: Integrating MFA with Vendor Portals

Integrating MFA is essential for businesses when they work with vendors. However, the implementation process should not be overlooked. When implementing MFA for vendor portals, organizations must consider the following:

1. Assets and resources

When implementing MFA, businesses must determine which of their network assets contain sensitive information and prioritize MFA protocols accordingly. Doing so can help them make the most use of authentication and authorization protocols, as they will be safeguarding their most important assets first.

1. Level of authentication

After determining which assets need MFA security, businesses must determine the extent of authentication and authorization needed for each asset. Some assets may not contain highly sensitive information, and standard MFA protocols may be sufficient in this case.

1. Actions that trigger authentication

Next, the companies must define which vendor actions will trigger the authentication protocols. Common examples of such actions may include access requests to restricted sections of a network database or a deviation in behaviors from the user’s normal course of action.

1. Protocol deployment and monitoring

Lastly, the organizations need to consider how the protocols will be deployed. In most cases, it’s better to secure high-priority assets first and then deploy MFA protocols on the remaining assets. Once deployed, organizations must develop monitoring schedules to ensure that the protocols are working as configured.

Real-world Scenarios: MFA’s Role in Thwarting Breaches

MFA’s role in preventing data breaches is paramount as it can help businesses eliminate unauthorized access. Network vulnerabilities being exploited are common in the business world and lead to information theft and data breaches if MFA is not used. Some common examples where MFA could have protected an organization include:

• The Equifax data breach where 145 million records were at risk of being exposed.
• The Deloitte data breach where a hacker gained access to the company’s email system by acquiring login credentials.
• The Timehop breach which led to 20 million records being lost as a hacker had gained access to the network.

Overcoming Common Challenges with MFA Deployment

MFA deployment can pose challenges like user resistance and integration issues. To overcome user resistance, you should educate users about the benefits and risks of MFA and make the authentication process as seamless and user-friendly as possible. To avoid Integration issues, use standard and open protocols for authentication and test the system before implementation.

Best Practices in MFA Settings for Vendors

Most businesses overlook the importance of setting MFA protocols for vendors. However, this can lead to security issues arising from misconfiguration. Some best practices in MFA settings for vendors include:

• Focusing on ease of use.
• Utilizing a variety of authentication factors.
• Educating users on MFA.
• Leveraging adaptive MFA protocols.
• Monitoring the effectiveness of MFA protocols.

Looking Ahead: Advanced MFA Technologies and Vendor Management

Although the implementation of MFA in the businesses set up took time, it is growing and becoming a security requirement in many sectors. The future of MFA will likely be centered around using robust methods across all access portals with an increasing focus on granular and flexible control and implementation.

Final Thoughts On MFA

As the companies, whether local or internationally acclaimed, continue to grow, they, at some point, need to have the assistance of a third party for several purposes. This access to the company’s network resources can pose threats to sensitive information as unauthorized users may gain access. However, using MFA for vendor access helps businesses limit unauthorized access and ensure data protection effectively.
