Enhancing VPN Security: Download Our Comprehensive Guide from Secfense

VPNs have long been trusted as a secure solution for remote access to company resources. However, recent reports have revealed vulnerabilities that pose significant risks to organizational data. As companies continue to adapt to remote and hybrid work models, it is essential to understand these threats and implement robust security measures.

Our latest e-book, “Secure Your VPN: How to Protect Company Data from Cyberattacks on VPNs,” offers an in-depth analysis of VPN security. This comprehensive guide covers a range of topics to help you strengthen your VPN infrastructure.

Understanding VPNs

What is a VPN?

A Virtual Private Network (VPN) creates an encrypted tunnel between a user’s device and the VPN server, securing internet connections and enabling safe access to company resources. VPNs are crucial for companies with multiple applications and large amounts of data stored in internal data centers, as they ensure that employees can securely access these resources from any location.

Benefits for Companies

VPNs offer several advantages, including:

  • Data Security: VPNs provide encrypted connections, protecting confidential data from unauthorized access and eavesdropping.
  • Secure Remote Access: Employees can safely access company resources, applications, and files remotely, even from public Wi-Fi networks.
  • Protection Against Attacks: VPNs add a layer of protection against various cyber threats, including man-in-the-middle attacks.
  • Bypassing Geographical Restrictions: VPNs allow access to resources and services that may be geographically restricted, enhancing operational flexibility.
  • Increased Work Flexibility: Employees can work from anywhere, boosting mobility and productivity.

Identifying VPN Security Problems

Common Vulnerabilities

While VPNs are designed to secure communications, they are not immune to threats. Common vulnerabilities include:

  • Credential Hijacking: Attackers often target the authentication process to steal login credentials through phishing or other methods.
  • DDoS Attacks: Cybercriminals may launch Distributed Denial-of-Service (DDoS) attacks to overwhelm VPN servers, causing disruptions.
  • Weak Encryption Attacks: Older encryption algorithms like PPTP are susceptible to attacks, while modern algorithms like AES-256 are more secure.
  • Zero-Day Vulnerabilities: VPNs can be exposed to previously unknown vulnerabilities that attackers exploit before patches are available.
  • Authentication Bypass Attacks: These attacks allow intruders to bypass the authentication process and gain unauthorized access to systems.

Real-World Cases

Recent incidents involving major VPN providers highlight the importance of robust security. For example:

  • Fortinet: A security vulnerability in FortiOS allowed code execution without authentication via a crafted HTTP request.
  • Ivanti: Combined vulnerabilities in Ivanti’s Connect Secure VPN allowed authentication bypass and command injection attacks, compromising internal resources.

Strengthening VPN Security

Effective Solutions

To combat these threats, it is essential to implement strong authentication mechanisms. These solutions include:

  • Multi-Factor Authentication (MFA): Adding a second authentication factor ensures that even if credentials are stolen, unauthorized access is prevented.
  • Passwordless Methods: Eliminating passwords reduces the risk of credential theft. Modern solutions use biometric and cryptographic methods for secure access.

Secfense Solutions

Secfense offers advanced tools to enhance VPN security:

  • User Access Security Broker: This solution integrates MFA, including FIDO2 standards, into any web application without extensive programming.
  • Full Site Protection: Protects the VPN login page, making it invisible to unauthorized users and securing the access point.

Implementing Strong Authentication

Advanced Methods

Strong authentication involves at least two independent verification steps, which can include:

  • Something the User Knows: Passwords or PINs.
  • Something the User Has: Phone or security token.
  • Something the User Is: Biometrics like fingerprints or facial recognition.

These methods ensure that even if one factor is compromised, the overall security remains intact.

FIDO2 Standards

The FIDO2 standard, developed by the FIDO Alliance, promotes phishing-resistant authentication. It uses biometrics and cryptographic methods to provide secure and user-friendly authentication. Secfense’s solutions are aligned with FIDO2 standards, offering advanced security for your VPN infrastructure.

Integration and Implementation

Secfense solutions are designed to integrate seamlessly with popular VPNs like NetScaler Gateway and Ivanti Secure Access. Our tools support the Security Assertion Markup Language (SAML) protocol for single sign-on (SSO), enabling secure access to multiple applications with one set of credentials.

Full Site Protection

Full Site Protection ensures that only authorized users can access the VPN server login page. Unauthorized users cannot even see the page, reducing the risk of attacks on the login interface.

Secfense IdP

Secfense Identity Provider (IdP) supports passwordless authentication, replacing traditional passwords with FIDO passkeys. This approach enhances security and user convenience. Secfense IdP also facilitates integration with various Identity and Access Management (IAM) services, ensuring flexibility in managing user identities.

We are faced with new challenges every day. We must always be one step ahead of the attackers and know what they are going to do before they do it. We are convinced that the User Access Security Broker will bring security to a new level, both for those working at the office and from home. For us, working with Secfense is an opportunity to exchange experience with developers who put great value on out-of-the-box thinking.

As part of the pre-implementation analysis, we verified that users utilize a wide range of client platforms: desktop computers, laptops, tablets, smartphones, and traditional mobile phones. Each of these devices differs in technological advancement, features, and level of security. Because of this, and also due to the recommendation of the Polish Financial Supervision Authority (UKNF), we decided to introduce additional protection in the form of multi-factor authentication mechanisms based on FIDO. As a result, users of our applications can log in safely, avoiding common cyber threats such as phishing, account takeover, and theft of their own and their clients’ data.

Before investing in Secfense, we had the opportunity to talk to its existing clients. Their reactions were unanimous: wow, it’s so easy to use. We were particularly impressed by the fact that implementing their solution does not require the involvement of IT developers. It gives Secfense a huge advantage over the competition, and at the same time opens the door to potential customers who so far were afraid of changes related to the implementation of multi-factor authentication solutions.

Even when the network and infrastructure are secured enough, social engineering and passwords can be used to gain control of the system by attackers. Multifactor authentication is the current trend. Secfense addresses this and allows you to build zero trust security and upgrade your current systems to passwordless applications within minutes, solving this problem right away,” said Eduard Kučera, Partner at Presto Ventures and cybersecurity expert – former Director in hugely successful Czech multinational cyber security firm Avast.

One of the biggest challenges the world is facing today is securing our identity online. That’s why we were so keen to have Secfense in our portfolio. They make it possible to introduce strong authentication in an automated way. Until now, organizations had to selectively protect applications because the deployment of new technology was very hard, or even impossible. With Secfense, the implementation of multi-factor authentication is no longer a problem, and all organizations can use the highest standards of authentication security.

Two-factor authentication is known to be one of the best ways to protect against phishing; however, its implementation has always been difficult. Secfense helped us solve that problem. With their security broker, we were able to introduce various 2FA methods on our web applications at once.
