Businesses are transitioning to Always On VPN solutions at a fast rate due to its incredible capability of providing non-stop connections, especially in places where the remote work model is adopted. However, since this is relatively a new approach to VPN, we see some common mistakes in the deployment process that put sensitive data at risk.
For this reason, we want to go over the importance of layered security in Always On VPN deployments and show you everything you need. By the end, you’ll be able to understand why you need multi-layered security in these VPN solutions instead of a straightforward one.
Understanding the Basics: What is Layered Security?
We first need to understand the concept of layered security to see why it is so important for Always On VPN deployments. Layered security is a strategic approach that involves the implementation of multiple lines of defense against cyberattacks to protect networks, sensitive data, and other digital assets. This approach understands that not a single security service will be able to counteract all kinds of attacks, instead, it believes in the cooperation of several tools and technologies.
Layered security operates on the principle that even if one of the security controls is bypassed, one of the tools or technologies will be able to stop the intruder from going forward. You can think of it as a physical building; from access control to surveillance to alarms, complements and reinforces the others.
In Always On VPN deployments, layered security is a critical precaution against the numerous threats targeting remote connections. It encompasses a spectrum of security measures, ranging from firewalls and intrusion detection systems to encryption and multi-factor authentication. These elements work together to create a holistic defense, making it exceptionally challenging for cybercriminals to compromise the network or access sensitive information.
The Evolution of Cyber Threats: Why Traditional Defenses Fall Short
Cyber threats have undergone a significant evolution in recent years. They become incredibly complex and pervasive. The traditional security methods, which were previously considered highly robust, have fallen short when fighting off these advanced attacks.
In the early days, a firewall and antivirus software would mostly be sufficient to protect a device or a network against all the cyberattacks they fear. However, we now see the range of threats has expanded and there are new methods. We see emerging threats such as advanced malware, phishing attacks, or zero-day vulnerabilities which prove that not a single security service is the silver bullet.
Traditional defenses rely on signature-based detection, which means they can only identify known threats. This leaves them blind to novel and rapidly evolving attack techniques. Always On VPN deployments are particularly susceptible to these threats due to their constant connectivity. Remote users become attractive targets, making it imperative to change security strategies. This is where the concept of layered security comes into play. It employs a multi-faceted approach that includes intrusion detection, behavioral analysis, and robust encryption.
Key Components of a Layered Security Approach for VPNs
You’ll be putting your digital resources at risk if you don’t follow security best practices for Always On VPN. That’s why we got your back and listed all the essentials you need for this VPN solution.
Firewalls and Intrusion Detection Systems (IDS/IPS)
As the initial line of protection, firewalls filter network traffic and stop illegal access. They may actively monitor network activity, spot unusual activity, and react to any attacks in real time when paired with intrusion prevention systems (IPS) and intrusion detection systems (IDS).
Access Control
Access control is everything when you need a layered security approach for your VPN. You need to be able to understand the behavior of your end users and adjust access permissions accordingly. This will effectively prevent any internal threats while the other measures protect the network from outsiders.
Encryption
Data needs to be kept safe both at rest and in travel. Encryption is the go-to way to protect sensitive data when your remote users communicate with the central network. Using strong encryption protocols, you’ll simply render the data unreadable to any potential intruders.
Endpoint Security
It is essential to secure the devices used to establish a VPN connection. Patch management, device integrity checks, and antivirus software are examples of endpoint security techniques that make sure endpoints adhere to security guidelines before allowing them to access the network.
Multi-Factor Authentication (MFA)
When you need to protect a private network, you need to be able to verify your end users with a robust authentication method. Passwords don’t cut it anymore, especially with remote users in organizations. Implementing MFA is a must to ensure users are verified through more secure methods such as biometrics or OTPs.
Risks of a Single-Point Security Model in VPN Deployments
In VPN deployments, relying on a single-point security paradigm exposes enterprises to serious dangers. This kind of paradigm rests on a single line of defense that, if compromised, might have some really negative results. With this method, a single weakness can harm the whole network.
Cyber attacks are ever-changing, frequently focusing on particular weaknesses, and firms that solely rely on one security layer may be left open to new attack strategies. Layered security is essential for strengthening VPN installations because it offers a flexible and durable defense against the many risks that current cyberattacks might provide.
Role of Encryption and Protocols in Layered VPN Security
Encryption scrambles data into an unreadable format, making it indecipherable to anyone without the proper decryption key. In the context of VPNs, this means that data transferred between the user’s device and the VPN server is protected from prying eyes. Common encryption protocols like SSL/TLS, IPsec, and OpenVPN are the foundation of VPN security.
These protocols not only encrypt data but also establish secure channels for data transmission. They provide the framework for authentication and data integrity, ensuring that data remains confidential and unaltered during transit.
The Importance of Multi-Factor Authentication in VPNs
The use of Multi-Factor Authentication (MFA) in VPN security is essential. It is insufficient to rely exclusively on standard username and password authentication in an era of increasing cyber risks. By requiring users to give multiple types of authentication, such as something they know (a password), something they have (a token or smartphone), or something they are (biometric data), MFA adds an additional layer of security to the system.
This greatly improves security since an extra authentication factor serves as a strong barrier against unwanted access, even in the event that login credentials are stolen. MFA is a crucial component of layered security strategies, which greatly increase the attack resistance of VPN deployments.
The Future of Always On VPN
Always On VPN will continue to spread as the industry standard VPN solution, replacing the traditional VPN services with its continuous connection and added security benefits. It is also
likely that this security solution will be coupled with modern frameworks and technologies, such as the use of MFA, threat detection solutions, or Zero Trust security. In a world where connection means everything, Always On VPN will be the number one choice to leverage remote work and stay in connection with your teammates.
