Figure 6.4 Having.a.disaster.recovery.plan.is.important.
The. physical. space. where. you. store. your. data. will. need.
to.be.secured.with.access.controls..If.you.are.an.individual,.
that.could.be.as.simple.as.locking.your.laptop.or.desktop.to.
your.desk.with.a.cable.lock..A.small.organization.might.sim-
ply.have.a.locking.closet.or.small.room.where.you.store.your.
servers.and.other.networking.equipment..However,.keep.in.
mind. that. part. of. your. secure. storage. responsibility. will. be.
ensuring.that.the.devices.in.those.storage.areas.are.not.sub-
ject.to.overheating.or.power.outages.
You. will. need. to. ensure. that. there. is. suficient. cooling.
capacity. and. some. type. of. redundant. power. supply. or. bat-
tery.backup.for.those.storage.devices..Computer.systems.can.
be.destroyed.by.overheating,.and.if.they.shut.down.unexpect-
edly.due.to.a.power.outage,.data.can.be.destroyed.
In. a. larger. organization. there. will. most. often. be. a. spe-
cial.data.center..It.will.have.robust.physical.security.including.
guards,.cameras,.fences,.and.often.several.layers.of.secured.
access.using.authentication.mechanisms.such.as.card.or.in-
gerprint.or.other.biological.scanners,.all.of.which.are.care-
fully.monitored.and.recorded.
There.will.also.be.redundant.systems.for.cooling,.heating,.
and.power.backup.systems..If.you.have.never.visited.a.large.
data.center,.I.recommend.arranging.a.tour..They.can.be.quite.
impressive.and.complex..One.very.large.center.that.I.toured.
