Scripts:. In. a. programming. context. Scripts. are. a. type. of.
programming.language.run,.or.executed,.by.another.
program..For.example,.Java.Script.is.run.by.the.Web.
browser. running. on. the. user's. PC.. In. the. context. of.
system.testing.and.user.acceptance.testing,.scripts.are.
used.as.the.predetermined.input.data.to.test.the.sys-
tem..Scripts.should.not.only.state.the.precise.data.to.
be.input,.but.also.the.expected.response.from.the.sys-
tem..As.user.acceptance.testing.proceeds,.the.results.
from.running.the.scripts.will.be.recorded,.as.will.the.
overall.system.conditions.at.the.time.to.allow.develop-
ers.to.more.easily.debug.errors.
. . Scripts. can. take. the. form. of. input. data. sheets. for.
manual.input,.or.can.be.a.series.of.iles,.the.process-
ing.of.which.simulates.the.generation.of.transactions.
across.the.network.to.the.system..This.latter.approach.
can. allow. for. signiicant. volumes. to. be. processed..
However,.it.is.essential.to.proceed.carefully.as.errors.
can.so.easily.compound.making.analysis.a.nightmare.
Secure Socket Layer (SSL):. A. transmission. protocol. that.
employs.encryption.of.data.
Security:. An.attribute.of.information.systems.which.includes.
speciic.policy-based.mechanisms.and.assurances.for.
protecting.the.conidentiality.and.integrity.of.informa-
tion,. the. availability. and. functionality. of. critical. ser-
vices,.and.the.privacy.of.individuals.
Security Administrator:. Individual(s). who. are. responsible.
for. all. security. aspects. of. a. system. on. a. day-to-day.
basis.. The. security. administrator. should. be. indepen-
dent. of. both. development. and. operations. staff. and.
often. holds. the. highest-power. password. on. the. sys-
tem. so. that. the. most. sensitive. activities. can. only. be.
undertaken.with.a.combination.of.both.system.admin-
istrator.and.security.administrator.top-level.passwords.
