1. What is Multi-Factor Authentication (MFA)

Multi-Factor Authentication (MFA, 3FA) adds an extra layer of security to your account, ensuring it’s really you when you log in. Instead of just entering your password, the system might ask for additional proof, such as a one-time code sent to your phone via MFA app, chatbot, push notification, SMS, or email. Or, you may need to answer a secret question, scan your fingerprint, or use the face ID feature.

This robust defense helps protect users’ accounts against cyber attacks and tricky situations where passwords might be at risk. Multi-factor authentication guards against phishing, man-in-the-middle attacks, brute force, and other password-related threats.

Multi-Factor Authentication is also referred to as two-factor authentication, 2-factor authentication, or 2FA. This is because, typically, a combination of two authentication factors is used during login to enhance user-friendliness.

2. Factors of Multi-Factor Authentication

Multi-factor authentication enhances security by requiring a combination of different authentication factors.

Currently, three main types of authentication factors are recognized:

  1. 1. Something you know: This includes passwords, usernames, or responses to secret questions like the name of your cat or your favorite author.
  2. 2. Something you have: A one-time code generated on your smartphone through an MFA app or received via SMS, chatbot in a messaging app, or email. Or, it can be a special device for one-time password generation called hardware OTP token. It resembles a key fob, USB drive, card, or calculator with a small 6 or 8-digit screen.
  3. 3. Something you are: Biometric data, such as fingerprint or retina scans, as well as face ID.

Multifactor authentication factors

Some security specialists mention a potential fourth factor – the user’s environment. Yet, there is ongoing debate about whether it’s appropriate to classify the user’s environment as a distinct factor. Nevertheless, within the realm of multi-factor authentication, we can delineate two additional factors:

  1. 4. Location Verification: Location-based authentication validates a user’s identity by considering their geographical location. For example, if an account registered in one country encounters login attempts from another location, the system, employing geographic and IP filters, will restrict access to the account.
  2. 5. Time-Based Authentication: This factor verifies a user’s identity by evaluating the timing of access attempts. It operates on the assumption that specific activities, such as logging into a work computer, typically occur within predictable time ranges. If an access attempt deviates from the expected timeframe, the system will deny access to the account.

3. How Multi-Factor Authentication Works

Signing into your account with just a username and password may seem simple, but it opens the door for anyone with this information to access your account from anywhere globally. This is where Multi-Factor Authentication (MFA) steps in to add an extra layer of security.

The success of multi-factor authentication lies in the strategic combination of various authentication factors, each compensating for the weaknesses of the other. This makes it tough for attackers since compromising all factors at once within a limited time is challenging. Even if one factor is compromised, the account stays secure, providing robust protection.

When MFA is enabled, the authentication process becomes more intriguing.

  1. 1. The first step is the usual username and password routine (something you know).
  2. 2. Then, you encounter the second factor—a unique identity verification step, which may be:

    • • Something you have: a one-time code generated on your smartphone through an MFA app or received via SMS, etc.
    • • Something you are: a fingerprint or face ID.

    Let’s say you choose the Protectimus Smart authenticator app as your second factor. Opening the MFA app on your smartphone reveals a dynamically generated 6-digit number. Inputting this number into the site grants you access.

How Multi-Factor Authentication Works

Now, if someone attempts to log in as you, they hit a roadblock. Even if they know your username and password, they’re stuck at the second factor. Without your smartphone, they can’t obtain the changing 6-digit code. This code, refreshed every 30 seconds, ensures security, even if they somehow knew yesterday’s code.

Breakdown of the MFA process:

  1. 1. Registration: Users create an account with a username and password, linking additional items such as a cell phone, physical hardware fob, or virtual items like an email address or mobile number. Biometric information, like fingerprints, can also be added for enhanced security.
  2. 2. Authentication: MFA-enabled users logging into a website input their username and password (the first factor) and are prompted to enter one-time codes or perform other actions from their MFA device (the second factor).
  3. 3. Reaction: Users complete the authentication by entering a one-time code, pressing a button on a hardware device, scanning their fingerprint, or clicking on the push notification.

4. The Significance of Multi-Factor Authentication

As organizations transition into the digital age and take on greater responsibility for safeguarding customer data, the need for robust security measures, including the adoption of multi-factor authentication (MFA), becomes apparent.

Relying on usernames and passwords, prove unreliable and susceptible to exploitation. Users often struggle to manage credentials, leaving them vulnerable to hacking.

Standards and regulations that require MFA

MFA is a vital solution, adding an extra layer of verification to online accounts and reducing the risk of unauthorized access due to compromised passwords. Multi-factor authentication protects accounts from phishing, man-in-the-middle attacks, brute force attempts, credential stuffing, keyloggers, and other password-related attacks.

Certifications and compliance mandates emphasize the importance of MFA. It plays a crucial role in meeting stringent requirements like PCI-DSS, PSD2, GDPR, NIST, FFIEC, NYDFS, NAIC, and other security standards. For businesses and organizations dealing with confidential data, financial transactions, or personal user information, implementing MFA is particularly crucial.

In essence, MFA strengthens digital security, aligns with industry standards, and provides a resilient defense against evolving cyber threats. It stands as an indispensable component in the ongoing battle against digital risks.

5. What Threats Does Multi-Factor Authentication Protects From

It provides protection against brute force attacks, account takeovers, phishing, man-in-the-middle attacks, credential stuffing, session hijacking, social engineering, dictionary attacks, keyloggers, and other password-related threats.

Phishing Attacks

MFA plays a crucial role in defending against phishing attacks where hackers trick users into disclosing login credentials through deceptive emails or fake websites. Requiring a second form of authentication adds an extra layer of security, diminishing the effectiveness of phishing schemes.

Brute Force Attacks

MFA addresses the risk of brute-force attacks, where hackers systematically attempt to crack passwords by trying numerous combinations. The additional authentication factor makes it significantly more challenging for attackers to gain unauthorized access, even if they manage to decipher a password.

Keylogging Exploits

MFA protects against keylogging attacks, where malicious software records keystrokes to capture sensitive information like passwords. Introducing an additional layer of authentication, such as a one-time code or biometrics, renders keyloggers ineffective in gaining complete access to user accounts.

Credential Stuffing

MFA disrupts credential stuffing attacks, where hackers use leaked username and password pairs to gain unauthorized entry. The secondary authentication requirement renders stolen credentials insufficient, fortifying digital systems against automated login attempts.

Session Hijacking

MFA guards against session hijacking, a type of attack where hackers steal an active user session for unauthorized access. Even if an attacker captures session data, the secondary authentication factor adds an extra layer of security, preventing successful compromise.

Social Engineering Attacks

MFA acts as a safeguard against social engineering attacks, where attackers manipulate individuals into divulging confidential information. Even if an attacker convinces a user to share login credentials, the secondary authentication factor adds an additional barrier to unauthorized access.

Man-in-the-Middle (MitM) Attacks

MFA helps prevent MitM attacks, where attackers intercept and manipulate communication to gain access to sensitive information. Additional verification steps, especially when utilizing CWYS feature for data signing, make it challenging for attackers to manipulate or intercept the authentication process.

Compromised Passwords

Passwords pose a risk when acquired by unauthorized individuals. For example, if a user records their password on a physical notepad, it becomes susceptible to theft, enabling unauthorized access. In contrast, 2FA enhances security by requiring validation from a secondary device after entering a password.

5. How Can I Set Up Protectimus for Different Applications and Accounts?

Setting up Protectimus for various applications and accounts is easy:

Simple Integration into Any Infrastructure: Protectimus streamlines the integration process with a variety of MFA plugins, ensuring quick connections to all systems within your infrastructure. Additionally, Protectimus offers a user-friendly API, even with its free plan, making integration straightforward. Developers can also leverage Software Development Kits (SDKs) available in popular languages like Java, PHP, and Python.

This approach ensures comprehensive two-factor authentication coverage across your infrastructure.

Efficient User Grouping and Management: Protectimus simplifies user grouping and management through resources. Within a single account, you can create multiple resources, each with its own set of administrators. For example, the protection needs for your end users and the admin panel may differ. One resource is tailored to end users, offering various token options for their convenience, including hardware tokens, 2FA apps, or connecting to the Protectimus chatbot on messaging services. Simultaneously, another resource within the same Protectimus account is dedicated to administrators, developers, and support staff. This resource imposes stricter authentication rules, allowing only hardware tokens and implementing filters based on time and location. This resource-based approach enables the effective management of diverse user groups, each with specific security requirements based on their access levels to sensitive data.
