We’ve all heard the saying that IPsec is the “silver bullet”. Well, I say that it’s not the silver bullet. It’s just one of those things that we should always remember. It doesn’t automatically protect us like a bullet.
Some people have asked us what IPsec is. Well, I think its a lot like another network level protocol, VPN. We use it to protect our systems from the Internet because we dont want our system to be compromised. In some ways, IPsec is the same thing. As long as our system is secure, we can use IPsec for everything else. The thing is though, the way I like to explain it is that IPsec is just like a VPN.
IPsec is essentially a way to have some sort of encrypted communication with your computer from a device on the Internet. You can use it for encrypting your Internet connection, allowing you to browse the Web, or encrypting your traffic to and from the Internet. One of the great advantages of IPsec is that your encryption keys are never exposed. They are never saved or stored, so nothing ever gets in the way.
The reason IPsec becomes so popular is that it’s a combination of the two. IPsec is very easy to use, but it’s also very expensive. It’s $10 for a month of the first year of use, and the cost of the second year is about $7.
In my opinion, the cost of IPsec has been greatly overstated. The vast majority of users encrypt their traffic using open-source software. I would say the cost of IPsec (or any standard encryption) will be very similar to that of the free open-source encryption packages like PGP and GPG. The only caveat is that you can only use IPsec when you are on your own network, or behind a router with public IP addresses.
Open-source software and free open-source software packages all have their strengths and weaknesses. Personally, I think the free open-source software packages are superior in every way to the proprietary software. For example, PGP is used in both Windows and OpenBSD, whereas the free open-source package for PGP is only available for Linux. I don’t think open-source software is perfect, but I think it is vastly superior to proprietary software.
The only real limitation is the strength of your router’s DHCP assignment table. A router’s DHCP assignment table is set up in such a way that all devices connected to the router (including your router itself) have the same IP address. If you connect to a router that doesn’t have a DHCP server assigned, then you’re stuck with the same IP address on all your devices for the entire duration of the connection.
A good part of the difference between ipsec and ipv4 is the speed. ipsec has a speed limit of 10Kbps, but this is much slower than you might think. So you don’t have to worry about the speed limit, but you also have to worry about the speed limit. For example, when I got my laptop home from work and it was just a few minutes away, I put it on a speed limit of 10Kbps.
ipsec, on the other hand, has a speed limit of 250Kbps, so on a slow connection you are not limited in any way. But then when you are really connected to the internet you are limited. I have a connection that takes me about an hour and a half on a 10Kbps connection, but on the other hand my connection is on a speed limit of 250Kbps.
The speed limit thing is important, but IPsec is important too, and it makes the difference. I can access the internet on my home network at my own speed and not worry about the slow speed limit, and be able to access my home network from anywhere in the world, at any speed. On the other hand, if I use my home network, I can’t use it to access the internet from anywhere else in the world at any speed.
