Keep in mind that for Social Security Disability Income (SSDI), there is a mandatory five-month waiting period from the date that Social Security determines your disability began (your onset date) to when your monthly payments can start.
IPSec is a set of IP extensions developed by IETF (Internet Engineering Task Force) to provide security services compatible with the existing IP standard (IPv.4) and also the upcoming one (IPv.6). In addition, IPSec can protect any protocol that runs on top of IP, for instance TCP, UDP, and ICMP.
To this end, a set of protocols called IP Security or IPSec was developed. In this section I provide a brief description of IPSec concepts and protocols. I begin with an overview of IPSec, including a discussion of the history of the technology and defining standards.
