||Free S/Wan VPN using IPSec in linux
|| IPSec (IP Security) is the security architecture for

Internet. It provides methods for establishing and assuring Privacy,
Integrity, Authenticity, Non repudiation, etc. Security related
services. As Internet is growing up into a global market, these
features are becoming more and more critical. In e-commerce the issue
of information security is paramount.
Now a days trend is toward mobility. The mobile nodes connect
to the Internet via wireless technologies so the bandwidth available
is limited. Further the computing capacity of mobile nodes may be
small. Security is much more critical in the case of Mobile IP as with
the mobility the chances of attacks increase due to external
environment. As nothing comes free IPSec involves its own overhead.
There are many weak and strong algorithms supported by IPSec. So
before choosing any security solution it becomes necessary to examine
the benefits provide by different algorithms and overhead
corresponding to them.
Free S/WAN is an ipsec implementation for linux which is free
and iteroperable with various security softwares like firewalls and
other IPSec implementations. So it is a good choice for VPN. I will
discuss some performance issues related to it.
