The Planning Stage is comprised of seven steps which establish either a design criteria or a piece of information needed to develop a criteria. The criteria include the assets to be protected, the threat, the level of protection, and any applicable design constraints. The 15 potential tactics included in the Security Engineering Design Process are moving vehicle bomb, stationary vehicle bomb, exterior, standoff weapons, ballistics, forced entry, covert entry, insider compromise, visual surveillance, acoustic emanations eavesdropping, electronic emanations eavesdropping, mail bomb, supplies bomb, airborne contamination, and waterborne contamination. The steps of the second, design, phase, include establishing design strategies, assessing opportunities and constraints, determining protective measures, integrating protective measures into a system, determining system cost and acceptability, and documenting the design.
