Cyber security is the umbrella term for all procedures to prevent unauthorized access to networks, servers, systems, and devices.Multi-factor authentication (MFA) verifies user identity using at least one authentication method. To prove their identity, users must employ MFA which is a vital component of any company's identity and access control policy.
Let's dive into what multi-factor authentication is, the benefits of it, and how you can set it up for your business.
What Is Multi-factor Authentication?
MFA, also known as Multi-Factor Authentication, is a purpose-built security framework. It enhances the privacy of online accounts and systems.
This advanced security system works by requesting unique personal information that only the verified user knows. Access to the system or a user's account is exclusively granted. This happens when the provided credentials align with the genuine information. This serves as an added layer of security, thwarting unauthorized access attempts.
While some may view it as a mere combination of a username and password, MFA authentication asks for more factors. Users must furnish at least two specific pieces of information to verify access.
- Something You Know: This includes information only known by the user, like a PIN or password.
- A Possession of Theirs: It could also involve a physical item, such as a smart card, security token, or mobile phone, owned by the user.
- A Quality They Have: These features depend on the user's distinct physical characteristics. This factor occasionally uses biometric security features These include a fingerprint reader, facial recognition system, or retinal scanner.
What Is MFA Authentication Good for?
Different factors must be employed in MFA systems to authenticate a user's identity.
A system with just a password and security questions isn't multi-factor authentication. The reason is that both are knowledge-based elements.Combining physical tokens and security questions enhances security. It involves both knowledge and possession factors.
Here are the types of attacks MFA authentication is best at preventing:
- Attacks through Phishing: Emails are often used in phishing attacks. Cybercriminals pretend to be trusted entities, such as banks or government agencies. They send fake emails that seem legitimate but carry harmful attachments or links.
- Man-In-The-Middle Attacks: During a Man-in-the-Middle (MITM) attack, the attacker eavesdrops on a user's connection with another party. They intercept interactions between the parties to corrupt data, steal passwords or personal information, and disrupt communications.
- The Brute Force Approach: In a Brute Force attack, cybercriminals generate and try numerous username/password combinations to gain access to a corporate system.
- Key Loggers: A keylogger is a type of spyware often installed by cybercriminals through viruses on a victim's device. It records every keystroke, capturing usernames, passwords, security question responses, banking and credit card information, visited websites, and more.
How Does Multi-Factor Authentication Work?
Multi-factor authentication works by collecting different forms of identification when you create an account. The system stores these details for future logins. Administrators can implement MFA for company accounts using authentication software.
This approach aligns seamlessly with single sign-on (SSO). This method allows users to access all their accounts using uniform credentials. Identity and access management solutions centrally handle these user management credentials. Consequently, the need for passwords becomes obsolete.
Alternatively, the login process involves multiple steps to verify additional ID information alongside the password.
Here's an overview of the multi-factor authentication process:
1. Registration
- Users create an account using a username and password.
- They connect additional items like a phone, hardware fob, email, mobile number, or app code to their account.
- These linked items contribute to uniquely identifying the user and should be kept confidential.
2. Authentication
- When a user with MFA-enabled tries to log in, they first provide their username and password.
- Simultaneously, they submit an authentication response from their MFA device (the second factor - what they have).
- If the system successfully verifies the password, it engages with the linked items.
- For instance, it might generate a numerical code on the hardware device or dispatch a code via SMS to the user's mobile device.
3. Reaction
- The user finalizes the authentication process by validating the additional items. This could involve entering a received code or pressing a button on the hardware device.
- System access is only granted when all the provided information, including the extra factors, is verified successfully.
4. Implementation of the process
The implementation of multi-factor authentication can vary, and here are some examples:
- Two-Factor Authentication (2FA): The system asks for the user's password plus one more form of ID, commonly known as two-factor or two-step authentication.
- Third-Party Authenticator Apps: Instead of the system itself, a third-party application, known as an authenticator, verifies the user's identity.
- The user enters a passcode generated by the authenticator, which then confirms the user's identity to the system.
- Biometric Verification: During verification, the user provides biometric data like fingerprints, retinas, or unique physical features.
- Device Recognition: The system may request multiple authentications only during the initial access from a new device.
- Later, on the same device, they only need to enter their password.

Why use more than one authentication factor?
Let's peel back the layers of individual authentication factors. When each factor is on its own, it can sometimes show security weaknesses due to how users act, their habits, or tech limitations.
Think about how we use our memory for passwords and PINs, known as knowledge-based authentication. This often leads to simple, rarely changed passwords that hackers love.
Location-based authentication can be tricked by hiding network traffic origins. Even behavior-based authentication, while it sounds secure, can sometimes be copied by cybercriminals.
On the flip side, biometric and possession-based authentication factors are like strong fortresses. Combining them in a multi-factor setup significantly reduces the chances of unauthorized access, making it tough for hackers.
Benefits of MFA Authentication
Before relying solely on strong passwords, consider the benefits of MFA Authentication:
- Enhanced Security: You must protect your data from phishing, social engineering, and other attacks. Using physical tokens like security keys and MFA credentials enhances system security.
- Supports Remote Work: While on-site security is essential for enterprises, MFA ensures secure remote access for authorized individuals even when staff is off-site.
- Boost Your Credibility: In an age of growing tools like Google Authenticator, users expect businesses to prioritize data security. They appreciate the added safety, even if it may seem slightly inconvenient. This enhances your company's credibility and trustworthiness.
- Save Money on Cybersecurity Recovery: Due to cloud computing's popularity, sensitive data is easily accessible remotely. The costs associated with cyberattacks can be substantial. These include potential ransom payments, security re-establishment expenses, and the risk of losing clients' trust. You can avoid these financial pitfalls and save resources by proactively securing your assets.
Best Practices for MFA Authentication Set-Up
Users should remain cautious about unsolicited emails, especially those requesting personal or financial information. Here are some key access management strategies:
- Define User Roles
Implementing user roles isImplementing user roles is crucial in the context of MFA authentication. It allows you to fine-tune access control restrictions. For example, you can grant privileged admin users more access than regular end users. - Enforce Strong Password Policies
Maintaining strong password policies is essential, whether or not you utilize MFA authentication.. Even with multiple authentication factors, stringent regulations should be in place. Implement rules that create passwords combining upper and lower-case letters, digits, and special characters for added security.
- Regularly Rotate Security Credentials
Frequently rotate credentials and automate password changes for robust MFA security. - Adhere to the policy of least privilege: Follow the principle of least privilege when implementing MFA authentication. Begin with minimal access and gradually grant more privileges as confidence and credentials validate.
Examples of multi-factor authentication
Here are some examples of how businesses can implement multi-factor authentication:
Remote Employee Access:
- A company aims to provide remote resource access for its employees.
- The company enforces multi-factor authentication.
- This means employees need login credentials, a hardware fob, and a fingerprint scan on company-issued laptops.
- The company has rules based on employee IP addresses.
- When working from home, two-factor authentication is required, while using other Wi-Fi networks.
On-Site Employee Access Only:
- A hospital needs to grant all employees access to its health applications and patient data while on-site.
- The hospital provides proximity badges to employees for access to these applications during their shifts.
- Employees log in and tap their badge to a central system at the start of each shift.
- Throughout the shift, they can access all resources with a single badge tap, eliminating the need for additional logins.
- Access rights linked to a single badge tap expire at the end of the shift.
- This helps minimize the risk of unauthorized access caused by lost badges.
Difference between multi-factor authentication and single factor authentication
You may know about 2FA, which means two-factor authentication. But a more powerful player in the game is MFA, or multi-factor authentication.
While 2FA insists on just two authentication factors, MFA goes further—it demands a minimum of two, three, or sometimes more authentication factors. Remember, 2FA is a part of MFA; MFA is the overall term, and 2FA is just one part of it.
When it comes to digital security, remember this: more layers mean more security. MFA excels here, taking you through multiple security checks, making it a stronger approach than 2FA. Some of these checks might not even be online; they could be physical tokens or keys, adding an extra layer.
