What is the difference between FortiClient IPsec VPN and SSL VPN?

Summary

In this article, I will discuss the difference between FortiClient IPsec VPN and SSL VPN, as well as answer some common questions related to SSL and VPN technologies.

Main Thought

IPsec VPNs and SSL/TLS VPNs serve different purposes. While IPsec VPNs connect hosts or networks to a protected private network, SSL/TLS VPNs securely connect a user’s application session to services inside a protected network.

Main Thought

FortiClient is a versatile VPN software that offers both SSL VPN and IPsec VPN capabilities. However, the VPN-only version of FortiClient does not include any support.

Key Points

1. SSL VPN vs. IPsec VPN

IPsec VPNs support all IP-based applications and appear as regular IP networks to applications. On the other hand, SSL VPNs provide secure remote access via a web portal and network-level access through an SSL-secured tunnel.

2. Is Open VPN IPsec or SSL?

OpenVPN is often referred to as an SSL-based VPN because it uses the SSL/TLS protocol to secure the connection. It also uses HMAC in combination with a digest algorithm for data integrity.

3. Advantages of SSL VPN

An SSL VPN offers data security and privacy, providing secure remote access and network-level access. It is particularly beneficial for protecting sensitive information.

4. SSL vs. IPsec: Choosing the Right Application

While IPsec VPNs allow users to connect remotely to an entire network and its applications, SSL VPNs provide remote tunneling access to specific systems or applications. The choice depends on balancing convenience for the end-user and security for the organization.

5. Security Comparison: SSL vs. VPN

Both SSL and VPN protocols contribute to data security. A VPN provides additional control over how data is encrypted and transferred, allowing for a balance between speed and security.

6. SSL vs. VPN Tunnel

An SSL VPN encrypts all data passing through the VPN connection, while HTTPS encryption only works between browsers and servers, and only if enabled.

7. SSL vs. VPN: Negotiating the Encryption Key

SSL uses a public certificate to derive the public and private keys, while VPNs generate a code called a nonce on both sides to generate the key.

8. Types of SSL VPNs

The two primary types of SSL VPNs are VPN portal and VPN tunnel. VPN portal allows one SSL VPN connection at a time to remote websites, while VPN tunnel enables remote users to access the SSL VPN gateway through their web browsers.

9. Disadvantages of SSL VPN

While SSL VPN is more secure than traditional VPNs and easier to set up and use, it can be slower and may not work with all web browsers.

10. Disadvantages of IPsec VPN

IPsec VPNs can degrade network performance due to the CPU overhead required for encryption and decryption of data passing through the network.

Choosing the right application comes down to a balance of convenience for the end-user and security for the organization.

Which is more secure SSL or VPN

A VPN can go a long way to filling in the holes that aren't covered by other security protocols. SSL is largely automatic, so there's not a lot you have to worry about in most cases. VPNs give you more control over how your data is encrypted and transferred, so you can balance speed and security.

What is the difference between SSL and VPN tunnel

A VPN and HTTPS both have the capability to encrypt your data, but a VPN just so happens to encrypt more. HTTPS encryption only works between browsers and servers, and that's only if it's enabled. A VPN, however, encrypts all data that passes through the VPN connection, no matter if certain settings are enabled or not.

How is SSL different from VPN

The way they negotiate the encryption key. SSL uses a public certificate to derive the public and private key from. For VPN both sides generate a code called a nonce that is put into an algorithm to generate the key.

What are the two most common types of SSL VPNs

There are two primary types of SSL VPNs: VPN portal and VPN tunnel. An SSL portal VPN enables one SSL VPN connection at a time to remote websites. Remote users access the SSL VPN gateway with their web browser after they have been authenticated through a method supported by the gateway.

The bottom line is that, although VPN and HTTPS can protect your data through encryption, they shouldn't be regarded as exclusive. In other words, not only is it good to combine HTTPS and VPN for increased privacy protection, but it's also recommended that you do so, especially on public, insecure networks.

Is SSL better than VPN

SSL is largely automatic, so there's not a lot you have to worry about in most cases. VPNs give you more control over how your data is encrypted and transferred, so you can balance speed and security.

What are the disadvantages of SSL VPN

As SSL VPN was mainly a web based VPN, applications or other network services that were not web based requires additional configuration which adds more complexity. In case the remote host requires to be always connected to the on site host, SSL VPN will not work as it doesn't have a capability to be always connected.

Why is SSL no longer used

There are several known vulnerabilities in the SSL protocol, and security experts recommend discontinuing its use. In fact, most modern web browsers no longer support SSL at all.

What is a disadvantage of a VPN that uses SSL instead of IPsec

The main drawback to an SSL VPN is that it can only be used to access web-enabled SSL applications. Also, the client can't access physical network resources such as printers.

What are three differences between SSL and IPsec VPN

The IPsec protocol suite operates at the network layer of the OSI model. It runs directly on top of IP (the Internet Protocol), which is responsible for routing data packets. Meanwhile, SSL operates at the application layer of the OSI model. It encrypts HTTP traffic instead of directly encrypting IP packets.

Why not to use IPsec

Disadvantages of IPSec

Compatibility issues: IPSec can have compatibility issues with some network devices and applications, which can lead to interoperability problems. Performance impact: IPSec can impact network performance due to the overhead of encryption and decryption of IP packets.

What is the drawback of SSL

Disadvantages of SSL

Cost of Certificate – It is possible to get a free SSL certificate, but this isn't recommended for a lot of reasons. Depending on the type of cert you buy, the price will vary quite a bit. However, when you consider the added level of security, the cost isn't really prohibitive for most websites.

When did SSL become obsolete

SSL 2.0: Launched in 1995 but has known problems with security. It was deprecated in 2011. SSL 3.0: Launched in 1996 but deprecated in 2015.

What are the disadvantages of IPsec

Disadvantages of IPSec

Performance impact: IPSec can impact network performance due to the overhead of encryption and decryption of IP packets. Key management: IPSec requires effective key management to ensure the security of the cryptographic keys used for encryption and authentication.

What is the major drawback of IPsec

Disadvantages of an IPSec VPN

CPU overheads: IPsec uses a large amount of computing power to encrypt and decrypt data moving through the network. This can degrade network performance.

Should I use SSL or not

An SSL certificate secures your website to protect important customer data from cybercriminals. If you collect personal information from customers, whether it's credit card numbers or something as simple as an email address, your website needs an SSL certificate, even if you don't sell anything.

What replaced SSL

TLS is the direct successor to SSL, and all versions of SSL are now deprecated. However, it's common to find the term SSL describing a TLS connection. In most cases, the terms SSL and SSL/TLS both refer to the TLS protocol and TLS certificates.
