Data recovery

hot site (subscription service) and a redundant site (owned by the company).

backup site should be 15 Miles recommended , critical environment 50-200 Miles

Software escrow means that a third party holds the source code, backups of the compiled code, manuals, and other supporting materials.

Disk duplexing means there is more than one disk controller. If one disk controller fails, the other is ready and available

Electronic vaulting makes copies of files as they are modified and periodically transmits them to an off site backup site (not real time its batch processing) bulk Information transfer

Remote journaling is off site data storage for real time transaction logs
tape vaulting auto transfer data to tape controller remote site

Block ciphers do not use public cryptography (private and public keys).

Type of testing includes
Structured walk-through
Checklist
Simulation
Parallel
Full interruption

The functions of a critical system can only be replaced by identical capabilities. Other functions can be performed manually.

Dual Data Center strategy also called redundent site or alternate site would be employed for applications, which cannot accept any downtime without impacting business.

property Insurance Replacement Cost Valuation (RCV) clause your damaged property will be compensated Based on new item for old regardless of condition of lost item

ACV (actual Cost Value)Value of item on the date of loss

disaster recovery plan is usually very information technology (IT) focused

The eight detailed and granular steps of the BIA are:
1. Select Individuals to interview for the data gathering.
2. Create data gathering techniques (surveys, questionnaires, qualitative and quantitative approaches).
3. Identify the company's critical business functions.
4. Identify the resources that these functions depend upon.
5. Calculate how long these functions can survive without these resources.
6. Identify vulnerabilities and the threats to these functions.
7. Calculate risk for each of the different business functions.
8. Document findings and report them to management.

Creating a BCP committee is part of the scope and plan initiation

Recovery Time Objectives (RTO) is the amount of time allowed for the recovery of a business function. If the RTO is exceeded, then severe damage to the organization would result. Recovery Time Objectives RTO would be defined as part of the recovery plan and not as part of the BIA.

The Recovery Point Objectives (RPO) is the point in time in which data must be restored in order to resume processing (mainly Business Transaction)

A data backup is the first step in contingency planning

Human Resources may not be a part of the BCP committee

Named PERILS Burden of proof that particular loss is covered is on Insured

The primary difference between them is that one type of policy covers what is "named" (included) in the policy while the other covers what is not included. A named peril policy is often a good choice for those business owners whose business is located in an area frequently hit by natural disasters such as hurricanes, tornados, or floods. Such a policy spells out the specific events for which you are covered. The cost of the premiums will depend on the location of the business and the likelihood of the specific peril(s). Anything not specifically named in such a policy is not covered.
An all-risk policy covers your business from damages caused by any type of disaster with the exception of those specifically excluded in the policy. Floods and earthquakes are two events that are typically excluded, but coverage for these types of disasters can be added to the policy for an additional fee.
Use of the All Risk form shifts the burden of proof onto the insurer to prove that a particular loss was not covered by the policy.

The Occupant Emergency Plan (OEP) provides the response procedures for occupants of a facility in the event of a situation posing a potential threat to the health and safety of personnel, the environment, or property. Such events would include a fire, hurricane, criminal attack, or a medical emergency

BCP is corrective control.
