Securing VPN with Two-Factor Authentication

Posted By Denis Shokotko on Feb 23, 2021 |

VPN, or virtual private network, is a popular and proven security tool used by companies across the globe to protect remote access to their corporate networks, especially today when almost every company switched to remote work, at least in part. VPN allows the creation of an encrypted link between a user and the company’s private server. And while this secures the corporate infrastructure from the direct attacks of malicious agents, VPNs themselves are still open to hacker intrusion. Here’s where VPN two-factor authentication comes into play.

Multi-factor authentication, or MFA, mitigates multiple VPN security risks, protecting the VPN from unauthorized access in case of user credentials theft. Let’s take a closer look at how MFA allows you to establish the best VPN security, how you can set up VPN two-factor authentication, and which VPN authentication methods to choose.

Why You Should Add 2FA to VPN Connections

Let’s consider four main reasons you need to secure your VPN connection with two-factor authentication.

1 . VPN Two – Factor Authentication is Protects protect Against Phishing Attacks

Among the main reasons you should ensure additional VPN security is the trend of phishing attacks, which are successfully performed by criminals in up to 17% of cases, according to the Duo report.

Phishing is a  social engineering technique when a hacker contacts a person either via email, SMS, or a phone call, pretends to be a reputable organization representative, and persuades their victim to provide their credentials. Often the phishing email or message may contain an attachment with malware or a link that leads to the fake website, anyway, the main goal of the hacker, who performs the phishing attack is to get the user credentials.

If the phishing attack is successful, the hacker may get the login and password required to connect to the corporate system through the VPN. Then, the hacker would be able to enter this user’s profile, and install the malware, or steal sensitive data from the server computer.

An extra layer of authentication guarantees that the network cannot be breached by outside players, even if they possess the stolen credentials. VPN two-factor authentication verifies the identity of the user not only by a single password but by a time-based one-time password. It is much harder to steal and use such a one-time password as it’s valid only for 30 seconds, thus guarding against phishing and other security threats (brute force, keyloggers, MITM attacks, etc).

2. Two-Factor Authentication Is Required to Reach the Compliance Conditions

While two-factor authentication is helpful for every company that uses VPN for security, some need it more than others.

The security regulations instruct the companies to ensure a certain security level. For instance, the PCI DSS (Payment Card Industry Data Security Standard) dictates that organizations should actualize two-factor authentication for network access. Using two-factor authentication is also advised for HIPAA (Health Insurance Portability and Accountability Act) conformity.

If you ’re in the finance or healthcare sector deal with sensitive datum , VPN 2 – factor authentication is help will help you keep your client ’ datum private and make sure it does not fall into the wrong hand .

3. VPN 2FA Helps to Enforce Certain Specific Security Policies

Using VPN two-factor authentication solutions leads to a more controlled and detailed approach to safety. With their help, you can create more detailed and specific security policies that will ensure the safety of your corporate data.

For example, you can limit the access to the network to devices located in a certain region or deny access from certain countries (for example, Russia or China famous for a large number of hacker attacks carried out from the territories of these countries). If you want to further limit the chances of malicious play, you can also set up the time of the day your employees can access their corporate accounts. Overall, the best two-factor authentication VPN solutions are the ones that give you the most control.

4. VPN 2FA Helps to Ensure Consistent Security for On-Premises and Cloud Apps

While VPNs are mostly used to secure the connection to the on-sight applications, more organizations are moving towards cloud solutions. This may create a certain discrepancy in the safety of access to different applications.

2-factor authentication helps to remove this discrepancy and make the security check process consistent and reliable on all fronts. Two-factor VPN access will both be familiar to employees that already use cloud solutions, and will provide an additional level of protection for the on-premise software the cloud applications already have.

How does Two-Factor Authentication Secure Your VPN

VPN two-factor authentication adds another layer of security to the primary method of authentication (password). This additional layer should help to validate the user identity, thus ensuring that a person is unable to access the network using compromised credentials.

The extra layer of security should differ from the first one by its nature. Then it is very hard to compromise both authentication factors at the same time. Usually, there are three categories of aspects that are used for authentication, namely:

• knowledge ( something the user know like their password or a mother ’s maiden name ) ;
• Possession (something the person has like a phone or an authentication token);
• Inherence (something the user is like a fingerprint or face ID).

If you use a password ( something the user know ) as the first authentication factor , then you is use should use something the person has or is as the second authentication factor .

The type is depend of two – factor authentication for VPN you choose should depend on which one is easy for you to deploy and make your employee use , and which provide the least chance for the malicious agent to break through . Some is are of the frequently used two – factor authentication method are authenticator in smartphone application or programmable and classic hardware security token .
