intelliHR's Disaster Recovery Plan outlines procedures to recover intelliHR following a disruption resulting from a disaster. This Disaster Recovery Policy is maintained by the intelliHR Security Officer and Privacy Officer.
Background
The following objectives have been established for this plan:
-
Maximize the effectiveness of contingency operations through an established plan that consists of the following phases:
- Notification/Activation phase to detect and assess damage and to activate the plan
- Recovery phase to restore temporary operations and recover damage done to the original system
- Reconstitution phase to restore system processing capabilities to normal operations
- Identify the activities, resources, and procedures needed to carry out intelliHR processing requirements during prolonged interruptions to normal operations
- Identify and define the impact of interruptions to intelliHR systems
- Assign responsibilities to designated personnel and provide guidance for recovering intelliHR systems during prolonged periods of interruption to normal operations
- Ensure coordination with other intelliHR staff who will participate in the Disaster Recovery Planning strategies
- Ensure coordination with external points of contact and vendors who will participate in the Disaster Recovery Planning strategies
Policy
Examples of the types of disasters that would initiate this plan are natural disasters, political disturbances, human-made disasters, external human threats, and internal malicious activities.
intelliHR defines two categories of systems from a disaster recovery perspective.
Critical Systems
These systems host application servers and database servers or are required for the functioning of systems that host application servers and database servers. These systems, if unavailable, affect the integrity of data and must be restored, or have a process begun to restore them, immediately upon becoming unavailable.
Non-critical Systems
These are all systems not considered critical by the definition above. These systems, while they may affect the performance and overall security of critical systems, do not prevent Critical systems from functioning and being accessed appropriately. These systems are restored at a lower priority than critical systems.
Threat and Risk Assessment and Management
There are many potential disruptive threats that can occur at any time and affect the normal business process. We have considered a wide range of potential threats and the results of our deliberations are included in this section. Each potential environmental disaster or emergency situation has been examined. The focus here is on the level of business disruption which could arise from each type of disaster.
The intelliHR IT Risk Assessment documents a fully detailed assessment of threats.
Testing and Maintenance
The Security Officer shall establish criteria for validation/testing of a Disaster Recovery Plan, and an annual test schedule, and ensure implementation of the test. This process will also serve as training for personnel involved in the plan's execution. At a minimum, the Disaster Recovery Plan shall be tested annually. The types of validation/testing exercises include tabletop and technical testing.
Tabletop Testing
The primary objective of the tabletop test is to ensure designated personnel are knowledgeable and capable of performing the notification/activation requirements and procedures as outlined in the Disaster Recovery Plan, in a timely manner. The exercises include, but are not limited to:
- Testing to validate the ability to respond to a crisis in a coordinated, timely, and effective manner, by simulating the occurrence of a specific crisis
Technical Testing
The primary objective of the technical test is to ensure the communication processes and data storage and recovery processes can function at an alternate site to perform the functions and capabilities of the system within the designated requirements. Technical testing shall include, but is not limited to:
- Process from backup system at the alternate site
- Restore system using backups
- Switch compute and storage resources to alternate processing site
Disaster Recovery Procedures
Notification and Activation Phase
This phase addresses the initial actions taken to detect and assess damage inflicted by a disruption to intelliHR. Based on the assessment of the Event, sometimes according to the intelliHR Incident Response Policy, the Disaster Recovery Plan may be activated by the Security Officer or the CTO.
The notification sequence is listed below
- The first responder is to notify the CTO. All known information must be relayed to the CTO
- The CTO is to contact the rest of the team and inform them of the event. The CTO is to begin assessment procedures
- The CTO is to notify team members and direct them to complete the assessment procedures outlined below to determine the extent of damage and estimated recovery time. If damage assessment cannot be performed locally because of unsafe conditions, the CTO is to follow the steps below
Damage Assessment Procedures
- The CTO is to logically assess damage, gain insight into whether the infrastructure is salvageable, and begin to formulate a plan for recovery
Alternate Assessment Procedures
Upon notification, the CTO is to follow the procedures for damage assessment with combined DevOps and Web Services Teams
The intelliHR Disaster Recovery Plan is to be activated if one or more of the following criteria are met:
- intelliHR systems will be unavailable for more than 48 hours
- Hosting facility is damaged and will be unavailable for more than 24 hours
- Other criteria, as appropriate and as defined by intelliHR
- If the plan is to be activated, the CTO is to notify and inform team members of the details of the event and if relocation is required
- Upon notification from the CTO, group leaders and managers are to notify their respective teams. Team members are to be informed of all applicable information and to prepare to respond
- The CTO is to notify remaining personnel and executive leadership on the general status of the incident
- Notification can be delivered via internal messaging, email, or phone
Recovery Phase
This section provides procedures for recovering the application at an alternate site, whereas other efforts are directed to repair damage to the original system and capabilities.
The following procedures are for recovering the intelliHR infrastructure at the alternate site. Procedures are outlined per team required. Each procedure should be executed in the sequence it is presented to maintain efficient operations.
Recovery Goal
The goal is to rebuild intelliHR infrastructure to a production state.
The tasks outlined below are not sequential and some can be run in parallel.
- Contact Partners and Customers affected
- Assess damage to the environment
- Begin replication of new environment using automated and tested scripts. At this point it is determined which AWS region we are able to create a new instance
- Test new environment using pre-written tests
- Test logging, security, and alerting functionality
- Assure systems are appropriately patched and up to date
- Deploy environment to production
- Update DNS to new environment
Reconstitution Phase
This section discusses activities necessary for restoring intelliHR operations at the original or new site. The goal is to restore full operations within 24 hours of a disaster or outage. When the hosted data centre at the original or new site has been restored, intelliHR operations at the alternate site may be transitioned back. The goal is to provide a seamless transition of operations from the alternate site to the computer centre.
Original or New Site Restoration
- Begin replication of new environment using automated and tested scripts - DevOps
- Test new environment using pre-written tests - Web Services
- Test logging, security, and alerting functionality - Dev Ops
- Deploy environment to production - Web Services
- Assure systems are appropriately patched and up to date - Dev Ops
- Update DNS to new environment - Dev Ops
Plan Deactivation
If the intelliHR environment is moved back to the original region from the alternative region, all provisioned services used in the alternate region should be removed according to intelliHR policy.
