Phase Inspection. 1  Inspect the electrical system as a whole including outlets, GFCI & AFCI protection, switches, fixtures, panels, circuit breakers & disconnects. 2  Inspect the plumbing for any visible leaks, drips, water supply, proper venting of the drains and waste lines.
Stateful inspection, also referred to as dynamic packet filtering, is a security feature often included in business networks. Check Point Software introduced stateful inspection in the use of its FireWall-1 in 1994. stateful firewall keeps track of the state of network connections (such as TCP streams or UDP communication) and is able to hold significant attributes of each connection in memory.
