Business Recovery and Continuity
Monitor, alert and plan how an organization responds to the loss of operations or data and resume suspended operations after any disaster strikes, recovering pre-event operational capacity.
Disaster Recovery
Set of procedures focused on recovering access to data and IT infrastructure after a disaster.
An organization's ability to respond to and recover from catastrophic events that negatively affect its operations or infrastructure.
It is the basis for the identification, evaluation and mitigation of disasters and the subsequent recovery strategies.
Disaster recovery planning coordinates the team for the effective restoration of systems and data after a disaster or attack.
Objective: minimize the damage of a disaster and help the organization return to its standard of operations as quickly as possible.
Business Continuity
It focuses on keeping company operations in action during a disaster.
Business continuity planning focuses on keeping operations running during the incident.
Objective: enable the organization to continue operating internally and providing services to customers, suppliers, and partners, even in the face of a disaster.
Goals
Disaster recovery has a dual purpose: maintaining and restoring key IT systems and infrastructure after an incident.
Maintenance: works by properly replicating and backing up data and assets to specific restore points.
Recovery: a reactive effort to recover functionality and control over systems and data that are infected or compromised.
Disaster Recovery Plan (DRP)
Systematic methodology by which a team allocates its resources to effectively regain control of key data and information systems after a disaster.
It can be used to resolve both minor and serious situations.
The effectiveness of disaster recovery plans lies in the ability to anticipate threats before they actually arise, and test various threat scenarios to ensure that the plan is working correctly.
After a cyberattack, teams need to have a disaster recovery plan to correct problems as quickly and effectively as possible.
Without this, every minute wasted can increase the cost of damage and recovery ability.
Disaster Recovery Plan: Fundamental Elements
Risk assessment: teams must thoroughly evaluate all potential threats and weaknesses in the organization's IT infrastructure, with special interest in areas that are most susceptible to cyberattacks.
Business continuity: determination of the procedures and resources to use to keep key business operations active in the event of a disaster.
Data archiving, backup, and recovery: documentation and implementation of maintenance processes to periodically back up key data and systems, including plans to restore these assets if they become compromised due to a disaster or attack.
Incident response: develop a flow of procedures and exercises that clearly articulate how a team should respond to a cyberattack, breach, or disaster, including how to identify and contain threats, assess damage, and restore affected systems.
Communication: instructions on how to communicate the situation to key stakeholders in the event of an attack; this includes employees, customers, suppliers, affected investors, and the media.
Training and education: intended for employees; based on good cybersecurity and disaster response practices, particularly on key exercises indicated in the organization's plan and what to be prepared for if a disaster occurs.
Testing and drills: consistent execution and practice of disaster recovery plans is vital to ensuring they are effective and that your team can be confident in their roles and responsibilities to handle threats as they arise.
Disaster Recovery Plan: Phases
Convene the team: determine the roles and responsibilities of all team members and departments within the organization.
Development of an incident management plan: exhaustive documentation of the procedures to be used to identify and report threats and cyber attacks.
Conducting a "Business Impact Analysis" (BIA): helps determine priorities and objectives for disaster recovery; focuses on identifying the systems, assets and processes fundamental to the organization and its operations.
Establishing a "Recovery Point Objective" (RPO): defines the acceptable amount of data loss measured over time.
Determine a "Recovery Time Objective" (RTO): determines the maximum acceptable time in which an organization's operations can be interrupted after a disaster.
Definition and documentation of the plan:
Dependencies: determine which systems and processes are interdependent and how they interact with each other.
Key suppliers: identify all key suppliers and partners for the organization's operations.
Locations: details about recovery locations, including primary and secondary alternatives.
Recovery procedures: identify and document the procedures and tools that will be used to recover compromised systems, applications, and data.
Communications procedures: determine what alternative technologies will be used to communicate, especially if primary communications systems are not available.
Testing protocols: used to evaluate the effectiveness of the plan and the specific steps of each protocol.
Consistently test the disaster recovery plan: schedule testing regularly to ensure the plan effectively handles all potential cyberattacks, errors, and disasters.
Regularly review and update the plan: evaluate and review the plan to ensure it is up to date.
Disaster Recovery Team
Chief Information Security Officer (CISO): responsible for the organization's overall cybersecurity strategy; helps lead disaster recovery efforts and monitor all information and data systems to protect against cyberattacks.
IT security team: specialized technical support team under the CISO; monitors and protects the organization's networks and systems; they are the first line of defense for mitigating cyber attacks and executing incident response processes.
Network administrators: may have more diversified positions for the maintenance and protection of the organization's networks, servers and other infrastructure; they play a key role in cybersecurity and disaster recovery for smaller operations.
IT operations and support: assist with the daily operation of the organization's servers, data storage, and other hardware systems; they may be responsible for technical support and problem resolution.
Risk management experts: assess and manage organizational risks related to cyberattacks and other IT threats; they are effective in predicting and simulating potential attacks to identify vulnerabilities; they help suggest improvements to prevent real attacks.
Legal affairs and compliance: work within a disaster recovery team to ensure that the organization's disaster recovery strategies and recovery efforts meet specific legal and regulatory requirements.
Crisis communications, media and public relations: often a separate department that remains integrated with disaster recovery efforts.
Business Continuity Plan (BCP) Manager: qualified professional capable of developing, maintaining and implementing an organization's disaster continuity plan, ensuring operations continue as planned; also responsible for testing and periodically updating the plan as needed.
Types of Disaster Recovery
Disaster recovery for data centers: focuses on the security of physical IT infrastructure and data backups; strategies revolve around using a failover page at a secondary location to maintain operational continuity during a disaster.
Cloud disaster recovery: strategies leverage cloud-based solutions to replicate and host an organization's physical and virtual servers; this approach provides automatic failover to the public cloud in the event of disasters, thereby eliminating the need for a secondary location.
Network disaster recovery: focuses on having backup data and locations and planning to regain control over network services.
Virtualized disaster recovery: a set of strategies designed to replicate workloads to an alternative cloud or physical location; provides cybersecurity teams with greater flexibility, efficiency, and ease of implementation.
Disaster recovery as a service (DRaaS): a commercial service provided by outsourced third parties that duplicate and host an organization's physical and virtual servers; the outsourced provider takes ownership of implementing and managing the most appropriate disaster recovery strategy and plan.
