Response Planning

Incident response and disaster recovery

Incident responseDisaster recovery

Introduced before; what do we mean?

Prof Hans Georg Schaathun Business Continuity Planning Autumn 2011 – Week 13 5 / 20

Response Planning

Incident response and disaster recovery

Incident response (IR)immediate actioneffective IR should mean negligible effect on operationserious disasters may be out of scope for IR

Disaster recoveryrestoring status quorestoration may take timeproduction loss may incur while we wait

Prof Hans Georg Schaathun Business Continuity Planning Autumn 2011 – Week 13 6 / 20

Response Planning

Business Continuity Plans

keep the business goingwhen incident response falls shortwhile we wait for disaster recovery

BCP supplements IR and DRThe scope is the most serious incidents

when IR/DR is insufficient

Response Planning

Why is BCP important?

Prof Hans Georg Schaathun Business Continuity Planning Autumn 2011 – Week 13 12 / 20

Continuity Strategies

Dedicated sites

Hot Sites a fully functional computing facility installed andconfigured for the organisation

Warm Site a partially installed computing facility. It typically includesserver hardware, but not applications and workstations.

Cold Site is just a spare building where a computing facility may beinstalled

Prof Hans Georg Schaathun Business Continuity Planning Autumn 2011 – Week 13 13 / 20

Continuity Strategies

Shared facilities

Time-Share several organisations share a hot/warm/cold site. Thisgives more value for money, assuming that twoorganisations will not hit simultaneous disasters...

Service Bureaus provide a service for a few, such as an agreement toprovide physical facilities in the event of a disaster

Mutual Agreements is some agreement between organisations toassist eachother in the event of a disaster.

Prof Hans Georg Schaathun Business Continuity Planning Autumn 2011 – Week 13 14 / 20

Continuity Strategies

Different facilities

Server and Data Centres High-security facilities. Security-awaremanagement. Good planning is common.

PC-s and Workstations Are often forgotten. Left to the attention ofindividual users.

Prof Hans Georg Schaathun Business Continuity Planning Autumn 2011 – Week 13 15 / 20

Continuity Strategies

Remote Storage

Backup is an obvious controlMost common threats to control are

media decay and disk failureuser errors (deleting the wrong file)

Rarer events include fire and theftRemote storage is essential to avoid losing both in the same eventBCP: roll out the backup on an alternate site

can you do it quickly enough?

Do you make remote backups as frequently as local backups?

Insurance and Responsibility

Continuity Planning versus Insurance

Is insurance an alternative to continuity planning?

Insurance will normally cover recovery.It will rarely cover consequential loss

such as lost productivity

Extended down-time may cause irrepairable loss

Conclusions

Business Continuity Planning supplements other plans for securityWhere other plans focus on resolving a situation

BCP only provides a temporary solutionto keep going while the other plans are executed

BCP often includes a backup facilityto run operations temporarily
