What is 2FA, and why is it Important?
It’s one of our mantras: Cybersecurity is of paramount importance to your business. Protecting sensitive information and preventing unauthorized access has become more important than ever. One of the most effective ways to do this is by implementing two-factor authentication, or 2FA. So, what is 2FA, and why is it important?
2FA is a security measure that requires users to provide two types of identification to access your network. The first identification is typically a password, and the second can range widely, from verification codes to a retinal scan. Yes, what was once seen only in Tom Cruise and Marvel movies is now a commonly used security feature. This blog itself is being typed on a laptop with a fingerprint scanner.
The idea behind 2FA is to add an extra layer of security. Passwords can be easily compromised through brute-force attacks, phishing scams, or by simply guessing or stealing them. With 2FA, even if a password is stolen, an attacker would still need access to the second factor to gain access to the account.
The second factor is usually a bit more difficult to acquire. It doesn’t have to be a retinal scan (which seems to be commonly overcome in movies through contact lenses or invasive methods resulting in eye patches anyway); there are several different types of 2FA.
“2FA is an essential form of security,” says MacguyverTech CEO Steve (Mac) McKeon. “Using 2FA in conjunction with passwords makes it much, much more difficult to compromise a network. We include it as part of our PVA (Persistent Vulnerability Assessment) packages. If your company doesn’t have 2FA set up yet, it really should.”
One of the most common forms of 2FA is text-based authentication, in which a verification code is sent to the user’s phone via SMS message. Another popular (and more secure) option form is app-based authentication, in which the user installs an app like Google Authenticator, that creates a numeric PIN. This PIN is valid for a short period of time and must be entered in addition to the user’s password.
Hardware tokens are another form of 2FA that involve physical devices, such as a USB key or smart card, that generate one-time passwords. These tokens can be more secure than other forms of 2FA, as they are less vulnerable to hacking or phishing attacks, but they can also be more expensive and less convenient.
Regardless of the method used, 2FA greatly improves the security of online accounts and services, making it more difficult for attackers to gain unauthorized access. This can help protect sensitive information, such as financial data, personal information, or business communications.
Additionally, 2FA can help businesses comply with regulatory requirements and standards, such as the Payment Card Industry Data Security Standard (PCI DSS) or the General Data Protection Regulation (GDPR). By implementing 2FA, businesses can demonstrate that they are taking appropriate measures to protect customer data and reduce the risk of data breaches.
Finally, 2FA can help build trust with customers and clients. If a customer knows your business is placing a great deal of emphasis on the security of their privacy and data, it will build your company’s reputation and ultimately increase your client base.
