Exploring 6 Authentication Methods Essential for a Comprehensive Cybersecurity Strategy

Authentication refers to the process that verifies the identity of a user, system, or device before granting access to data or resources. It’s an essential layer of protection in any network monitoring program. 

Choosing a method of authentication is no trivial task. It’s not one-size-fits-all but rather a tailored strategy that considers your unique business needs. 

To help you navigate this choice, we’ll delve into six different authentication methods. Each one comes with its strengths and weaknesses, and it’s important to understand them in the context of your business’s operations.

Password-based authentication

Password-based authentication is the most common and simplest authentication method for securing your network. Here, the “password” might be a username-password combination, passcode, or PIN. It’s intuitive, as many users are already familiar with such login methods. However, it’s also the easiest to exploit due to human errors like choosing simple passwords or using the same ones across multiple accounts.

It’s simple and cost-effective to use password-based authentication. However, it’s crucial to enforce strong password policies, like regular changes and complexity requirements, to avoid potential cybersecurity breaches.

Two-factor authentication/multi-factor authentication

Two-factor authentication (2FA) and multi-factor authentication (MFA) are upgrades to password-based security. Two-factor authentication generally involves a password (first factor) plus an additional layer of security (second factor).

A sample MFA process could include a one-time password sent through email or SMS in conjunction with something more secure like a fingerprint scan. Using a combination of security layers can significantly reduce the risk of data and software breaches.

Biometric authentication

Biometric authentication uses unique physical attributes like facial recognition, iris tracking, or fingerprint scanning. Biometric data offers a high security level as it’s unique to each individual and difficult to replicate.

For high-security enterprises, such as defense contractors, biometric authentication may be appropriate. Fingerprint scanning or facial recognition provides secure access to sensitive information.

Single-sign on authentication

Single sign-on (SSO) allows users to log in to multiple applications, software platforms, or websites with one set of credentials, reducing the cognitive load of remembering multiple passwords.

A healthcare company, for instance, might benefit from SSO if it uses several different databases to manage patient information. Because single-sign on places a great deal of emphasis on one set of credentials, malicious actors using AI to find said credentials is particularly concerning.

Token-based authentication

Token-based authentication relies on an authentication token, like a smart card or smartphone, containing the user’s credentials. It’s secure unless the physical token falls into the wrong hands.

Using a smart card with a password can add an extra layer of security to protect sensitive patient or customer data.

Certificate-based authentication

Certificate-based authentication uses digital certificates from a trusted source to verify identity. It’s useful for providing temporary network authentications to contractors or others needing temporary access.

Finding the best authentication fit for your needs

Organizations with sensitive data, highly regulated industries, or dispersed workforces may require advanced authentication processes. On the other hand, smaller organizations with lower budgets may find methods like biometric authentication cost-prohibitive or unnecessary, given the scale of their operations.

Here is a list of considerations you can use to help evaluate the right authentication method(s) for your organization:

• Industry: Some sectors, like healthcare and finance, deal with highly sensitive data and face strict compliance requirements, necessitating more robust authentication.
• Data sensitivity: The more sensitive the data, the stronger the authentication needed. Consider two-factor or multi-factor authentication if you’re handling high-stakes information.
• User tech literacy: If your end user base is not tech-savvy, simpler authentication methods, such as token-based authentication, may be more appropriate.
• Budget: While security is paramount, you may be unable to afford advanced biometric solutions, but can be well-served by password-based protocols or two-factor authentication.
• Size: Large organizations may require sophisticated, scalable solutions like LDAP or SSO, while smaller ones might get by with simpler methods.
