Why 2-Factor Authentication is Essential for Your Business’s Cybersecurity

Published on 29 March 2022

Cybersecurity threats pose a significant risk to businesses of all sizes. As a business owner or executive, protecting your company’s sensitive data and digital assets is paramount. One of the most effective tools in your cybersecurity arsenal is 2-factor authentication (2FA). This article will explore what 2FA is, how it works, and why it’s crucial for your business’s IT security strategy.

According to a recent study, 86% of data breaches involve credential theft. This alarming statistic underscores the importance of implementing robust security measures like 2FA to protect your business accounts.

What is 2-factor authentication?

2-factor authentication (2FA), also known as Multi-Factor Authentication (MFA), is an advanced security measure that adds an extra layer of protection to your accounts beyond just a password. When 2FA is enabled, users are required to provide two different authentication factors to verify their identity before gaining access to an account or system.

The concept behind 2FA is simple yet powerful: even if a cybercriminal manages to obtain an employee’s password, they still can’t access the account without the second authentication factor. This significantly reduces the risk of unauthorised access and potential data breaches.

For businesses, implementing 2FA across all company accounts and systems can dramatically improve overall cybersecurity posture. It’s particularly crucial for accounts that handle sensitive information, and financial data, or have access to critical business systems.

How does 2FA make my accounts more cyber secure?

The effectiveness of 2FA in enhancing cybersecurity cannot be overstated. A study by Google in collaboration with New York University and the University of California, San Diego found that on-device prompts, a form of 2FA, can block 100% of automated bots, 99% of bulk phishing attacks, and 90% of targeted attacks.

Passwords are not enough; they have historically been a weak point in cyber security and IT security. This is largely due to two reasons: Cybercriminals are always looking for and trying to crack passwords

Most people use simple, easy-to-remember passwords; often across multiple accounts. For example, 23 million accounts use ‘123456’ as their password. 

Here’s why 2FA is so effective for businesses:

1. Mitigates password vulnerabilities: Even with strong password policies, human error and password reuse remain significant security risks. 2FA provides a safety net against these vulnerabilities.
2. Protects against phishing: If an employee falls victim to a phishing attack and unwittingly reveals their password, 2FA can still prevent the attacker from accessing the account.
3. Adds a dynamic security layer: Unlike static passwords, many 2FA methods use one-time codes that change with each login attempt, making them much harder to crack or steal.
4. Increases awareness: The act of using 2FA reminds employees to be security-conscious, potentially improving overall cybersecurity behaviour.

Compliance: Many industry regulations and data protection laws now require or strongly recommend the use of 2FA, helping your business stay compliant.

What are the different types of 2-factor authentication?

There are several methods of implementing 2FA, each with its own strengths. Here are some of the most common types used in business environments:

1. SMS or Email Codes:
   • A one-time code is sent via text message or email.
   • Pros: Familiar to most users, easy to implement.
   • Cons: Vulnerable to SIM swapping attacks, less secure than other methods.
2. Authenticator Apps:
   • Apps like Google Authenticator or Microsoft Authenticator generate time-based one-time passwords.
   • Pros: More secure than SMS, works offline.
   • Cons: Requires employees to install and manage an app.
3. Biometric Authentication:
   • Uses fingerprints, facial recognition, or other biological traits.
   • Pros: Highly secure, and convenient for users.
   • Cons: Requires compatible hardware, potential privacy concerns.
4. Push Notifications/Trusted Device:
   • Sends a prompt to a trusted device for approval.
   • Pros: User-friendly, more secure than SMS.
   • Cons: Requires a smartphone and cellular/internet connection.

How to set up two-factor authentication?

Setting up 2FA for your business involves several steps:

1. Assess your needs: Determine which accounts and systems require 2FA protection.
2. Choose your 2FA method: Select the type(s) of 2FA that best suits your business needs and security requirements.
3. Implement the solution: This may involve configuring your existing systems or integrating a third-party 2FA solution.
4. Train your employees: Ensure all staff understand how to use the new 2FA system and why it’s important.
5. Create a rollout plan: Consider implementing 2FA in phases, starting with the most critical accounts.
6. Develop backup procedures: Establish protocols for when employees lose access to their second factor (e.g., lost phone for authenticator apps).
7. Monitor and adjust: Regularly review the effectiveness of your 2FA implementation and make adjustments as needed.

While this process may seem daunting, the long-term benefits to your business’s security far outweigh the initial setup effort. On average, 80% of data breaches could be prevented with basic actions, including two-factor authentication.

Add a layer of IT security with Bluebell

We are living in a world where long, difficult passwords are not enough. Cybercriminals can use tactics like phishing to get you to unknowingly reveal your password and grant them access to your data. 2FA can prevent this, by requiring an authorisation code to be entered when your account is accessed from an unknown device or suspicious location.

Implementing 2-factor authentication is a critical step in enhancing your business’s cybersecurity. By requiring two forms of identification, 2FA significantly reduces the risk of unauthorised access to your company’s sensitive data and systems, even if passwords are compromised.
