A remote access VPN is a Virtual Private Network(VPN) that allows individual users to establish a secure connection to a private network remotely. With this technology, employees, contractors, or authorized individuals can access an organization's resources on its internal network. They can do so as if they were directly connected to the network, even if and when they are travelling, working from home, or from an off-site location.
A remote access VPN comprises several components that work together to offer a secure remote connection to a private network (Given that the user is rightfully authorized). They are:
With the concept of remote work growing popular and being implemented vastly, VPNs have become a need in providing secure access to company resources from any location. They enable employees to connect to corporate networks securely, ensuring that sensitive data remains protected even when accessed from home or other remote locations.
However, the benefits of remote access VPNs don't just stop at enabling secure remote work. They extend to:
VPNs encrypt data in transit, protecting sensitive information from potential eavesdropping and interception. With this, any data transmitted over the internet remains secure and confidential. Not to forget, the encryption also enables protection against threats and unauthorized access.
We know that remote access VPNs offer employees the flexibility to access necessary resources from any location securely. This can improve productivity and enable flexible work arrangements, without the necessity to be present at the organization.
Remote access VPNs help with compliance by providing secure, encrypted connections that protect sensitive data in transit, which is crucial for meeting regulatory requirements like HIPAA, GDPR, and CCPA. They prevent unauthorized access to personal and confidential information by encrypting data and controlling user access, thereby ensuring that only authorized personnel can access sensitive information.
This encryption and access control help organizations adhere to data protection standards and avoid penalties associated with non-compliance. Additionally, VPNs can facilitate audit trails and monitoring, further supporting compliance efforts by providing transparency and accountability.
Here's how a remote access VPN works, step by step:
There are several types of remote access VPNs, they are:
Short for the Internet Protocol Security VPN, this uses the IPsec suite to secure communications over IP networks. IPsec operates at the network layer, providing a secure tunnel for data packets between devices. This VPN is widely adopted due to its compatibility with various operating systems and network devices, making it suitable for both site-to-site and remote access situations.
SSL VPNs use the Secure Sockets Layer (SSL) protocol, now commonly replaced by the more secure Transport Layer Security (TLS), to create encrypted tunnels between a user's device and an SSL VPN gateway. These VPNs are user-friendly as they operate through web browsers, eliminating the need for dedicated client software.
SSL VPNs are easy to deploy and manage, offering secure remote access with minimal configuration. They are particularly beneficial for environments where users are in need of quick, browser-based access to specific applications or resources without full network access.
Mobile VPNs are designed to maintain secure connections across various network changes, such as switching between Wi-Fi and cellular networks. They are ideal for environments that require persistent connectivity, such as public safety, for instance. Mobile VPNs ensure that application sessions remain active even when connectivity is interrupted or the devices enter hibernation. This VPN supports consistent roaming and is compatible with applications demanding constant connectivity, providing security through user and device authentication as well as data encryption.
