AWS provides businesses of all sizes with reliable, secure cloud solutions. IT managers must recognize that the biggest security threats come from internal vulnerabilities, and the way that employees are granted access to the cloud network.
Three of the most common options for securing your AWS cloud networks include:
Out of these, ZTNA provides the most secure option for granting access to resources stored on AWS. ZTNA’s primary advantage is that it eliminates the need to grant excessive privileges to those who need only limited access to data or files.
The following article explores ZTNA and AWS VPN solutions for securing AWS cloud networks.
Business VPNs typically use SSL/TLS instead of a dedicated VPN protocol such as IPSec or Wireguard. SSL VPNs are popular among companies due to their low cost and ease of use since they don’t require any special software, just a web-based interface.
An SSL VPN is a reliable option for providing workers and contractors with remote access to company servers on AWS without a complex implementation process.
An IPsec VPN is a type of VPN that relies on the IPsec protocol to establish and maintain a secure connection. Instead of an SSL connection on the application layer, IPsec creates a connection on the network layer.
AWS site-to-site VPN options rely on IPsec to create a secure connection between your branch office or data center and your AWS cloud network.
SSL VPNs encrypt HTTP data while IPsec VPNs encrypt IP packets. The position of the IPsec protocol on the network layer also gives users greater access control. However, increased access can also lead to security risks without the right procedures in place.
Zero Trust Network Access (ZTNA) offers enhanced security compared to relying solely on SSL VPNs or IPsec VPNs. A VPN grants access to an entire network, while ZTNA grants access to specific services and applications, and can even limit access based on device type. This narrows potential security gaps by preventing users from gaining broad access to services and information they don’t need, and restricting the devices they can use to access that data.
Along with greater scalability, implementing ZTNA also offers improved data protection. Since it only grants access to specific resources, ZTNA limits what a user can access on your AWS cloud network. This prevents a malicious actor from taking advantage of access to one resource in order to quickly breach the rest of the network.
AWS cloud networks are as secure as you make them. In the past, SSL VPNs and IPSec VPNs were the standard methods for secure remote connections. ZTNA is now the recommended strategy for connecting people to remote company servers. The new approach means you gain increased flexibility by allowing users to access specific applications or services instead of your entire network.
