Business Continuity

COSMODATA designs and implements Business Continuity solutions for businesses that want to reduce the risk of operational disruption and keep critical services available even in the event of failure, cyberattack or loss of infrastructure.

Business Continuity is not only about backups.

It concerns the organization's entire ability to keep operating when a serious incident occurs.

This means a combination of:

• of infrastructures
• of procedures
• alternative scenarios
• backup
• Disaster Recovery
• connectivity
• power protection
• documentation
• incident response
• human coordination

with one main goal:

limiting the business impact of an outage as much as possible.

Business Impact Analysis

The first step is to understand what is truly critical for the business.

We assess:

• critical applications
• core information systems
• servers
• data
• Internet connectivity
• telephony
• Microsoft 365
• cloud services
• business processes
• dependencies between systems
• requirements per department

This way, we can determine which systems must be restored first and which can wait.

Business-Critical Services

Not all systems are equally important.

A business may depend critically on:

• ERP
• CRM
• email
• Internet
• PBX
• file servers
• applications
• VPN
• Microsoft 365
• databases
• cloud services
• payment systems
• hotel systems
• operational platforms

A sound Business Continuity strategy clearly defines which services take priority.

RTO & RPO

Two key parameters are:

RTO – Recovery Time Objective

The maximum acceptable time until a critical service is restored.

RPO – Recovery Point Objective

The maximum acceptable period of data loss.

For example, one application may need to be restored within a few minutes, while a less critical service may be restored within several hours.

Proper prioritization helps design technically effective and financially realistic solutions.

Business Continuity Plan

An organized Business Continuity Plan describes what must be done when a critical service is unavailable.

It can include:

• critical business functions
• those responsible
• escalation paths
• alternative procedures
• communication with staff and customers
• recovery priorities
• emergency contacts
• technical procedures
• manual workarounds
• return-to-normal procedures

The goal is to avoid the need for improvisation at the moment of an incident.

Disaster Recovery

Business Continuity and Disaster Recovery work together.

Business Continuity defines:

how the business keeps operating.

Disaster Recovery defines:

how systems and data are restored.

The technical strategy can include:

• backup
• replication
• virtual machine recovery
• secondary infrastructure
• cloud recovery
• alternate site
• restore procedures

Backup Strategy

Data protection is a cornerstone of business continuity.

The strategy can include:

• local backups
• off-site backups
• cloud backups
• immutable backups
• encrypted backups
• database backups
• VM backups
• application-aware backups

with different retention policies depending on the importance of each system.

3-2-1 Backup Strategy

Where required, the well-known principle can be applied:

For increased requirements, the following can be added:

• immutable copies
• offline copies
• isolated backup repositories

for greater protection against ransomware and serious failures.

Restore Testing

A backup has no real value if it cannot be restored.

For this reason, periodic checks are carried out or planned, such as:

• file restore
• folder restore
• database restore
• virtual machine restore
• full server recovery
• application recovery

so that there is certainty that the data can actually be used when needed.

Internet & WAN Continuity

Loss of Internet can halt a large part of the operations of a modern business.

The following can be implemented:

• second ISP
• Dual WAN
• automatic failover
• 4G / 5G backup
• redundant VPN
• secondary WAN
• SD-WAN

so that an isolated telecom provider failure does not cause an overall outage.

Network Redundancy

Business continuity requires that the internal network infrastructure also be examined.

Depending on criticality, the following can be designed:

• redundant switches
• redundant uplinks
• backup firewalls
• multiple network paths
• redundant core infrastructure
• secondary access points

with the goal of limiting single points of failure.

Power Continuity

Power supply is a key availability factor.

The following can be used:

• UPS
• rack-mounted UPS
• redundant power supplies
• PDUs
• battery monitoring
• generator integration
• surge protection

so that critical systems remain available or shut down safely.

Server & Storage Resilience

For critical infrastructures, solutions such as the following can be designed:

• RAID
• redundant storage
• virtualization clusters
• high availability
• redundant power supplies
• replication
• failover systems

so that a hardware failure does not necessarily lead to a complete service outage.

Cloud Continuity

Cloud services can be an important part of the continuity strategy.

Depending on the case, they can be used for:

• backup
• replication
• alternate hosting
• emergency access
• Disaster Recovery
• document access
• remote working

so that the business can continue operating even if the primary site is unavailable.

Microsoft 365 Continuity

Business continuity must also take the Microsoft 365 environment into account.

The following can be examined:

• Exchange Online
• OneDrive
• SharePoint
• Teams
• identities
• MFA
• backup
• account recovery
• emergency access

so that email, files and collaboration remain available when there is a problem elsewhere in the infrastructure.

PBX & Communication Continuity

Communication is a critical function.

A continuity plan can include:

• SIP failover
• alternate routing
• cloud PBX
• mobile forwarding
• secondary Internet
• emergency numbers
• remote softphones

so that the business can continue communicating with customers and partners.

Remote Work Continuity

If the premises cannot be used, an immediate switch to remote working may be required.

Preparation can include:

• laptops
• VPN
• Microsoft 365
• Teams
• remote access
• cloud applications
• softphones
• security policies
• MFA

so that staff can continue working from an alternative location.

Multi-Site Continuity

For organizations with multiple facilities, a second site can be used as part of the continuity plan.

It can be applied:

• site-to-site replication
• secondary infrastructure
• alternate Internet access
• distributed services
• remote application access
• failover routing

so that one site can temporarily support the functions of another.

Ransomware Continuity

A ransomware incident can cause a complete interruption of business operations.

For this reason, a combination of the following is required:

The strategy can include:

• immutable backups
• network segmentation
• endpoint isolation
• clean restore environment
• alternate access
• incident response
• emergency communication procedures

so that recovery takes place without the threat returning along with it.

Cyber Incident Continuity

The business must be able to keep operating even when part of the infrastructure is isolated for security reasons.

The following can be provided for:

• manual procedures
• alternate communication channels
• emergency user accounts
• clean devices
• isolated recovery networks
• temporary systems
• prioritized restoration

so that the security response does not create a bigger business problem than the incident itself.

Physical Infrastructure Continuity

Business continuity is not limited to software.

Physical risks must also be considered, such as:

• server room failure
• overheating
• power failure
• flooding
• fire
• equipment failure
• physical access problems

and corresponding alternative plans exist.

Supplier & Vendor Continuity

The business may depend on third parties for critical services.

We examine dependencies on:

• Internet providers
• cloud providers
• telecom providers
• software vendors
• support partners
• hardware suppliers
• external datacenters

so that it is known what happens if a key partner cannot provide their service.

Single Points of Failure

One of the main goals of Business Continuity is the identification of Single Points of Failure.

Examples:

• one Internet connection
• one firewall
• one switch
• one server
• one storage
• one UPS
• one administrator
• one cloud account
• one supplier

Eliminating or reducing these points significantly increases the organization's resilience.

Emergency Communication Plan

In a serious outage, technical recovery is not enough.

There must be clear communication.

The plan can define:

• who informs management
• who informs employees
• who contacts suppliers
• how customers are informed
• which channels are used if email is not working
• what the escalation process is

Proper communication limits confusion and delays.

Documentation

Business Continuity must be documented.

The following can be created:

• Business Continuity Plan
• Disaster Recovery Plan
• network diagrams
• contact lists
• system inventories
• recovery procedures
• escalation matrix
• vendor details
• recovery priorities
• RTO / RPO tables
• emergency checklists

so that the plan can be used by more than one person.

Testing & Simulation

A continuity plan that has not been tested remains theoretical.

The following can be performed:

• tabletop exercises
• restore tests
• WAN failover tests
• power failure simulations
• DR tests
• remote working tests
• communication exercises

so that weaknesses are identified before a real incident occurs.

Tabletop Exercises

Not every test needs to cause a real outage.

Through organized tabletop scenarios, we can examine situations such as:

• ransomware
• Internet outage
• server failure
• Microsoft 365 account compromise
• power failure
• loss of primary site

and assess how the teams involved would react.

Recovery Priorities

In a serious outage, it is not possible to restore all systems at the same time.

A sequence can be defined such as:

so that technical teams know exactly where to focus.

Return to Normal

Recovery is not complete as soon as a temporary solution starts to work.

There must be a process for returning to normal operation:

so that new problems do not arise during the transition.

Post-Incident Review

An assessment must be carried out after every serious incident.

The following are examined:

• what happened
• what worked correctly
• what delayed the recovery
• which process failed
• what needs to change
• what investment is required

Every incident must lead to an improvement of the continuity plan.

Monitoring

Business Continuity is significantly strengthened when problems are detected early.

The following can be monitored:

• Internet connections
• servers
• storage
• UPS
• backup jobs
• replication
• network devices
• critical applications
• cloud services

so that a potential failure is addressed before it develops into a serious outage.

Reporting & KPIs

Readiness can be made measurable.

The following can be monitored:

• Backup Success Rate
• Restore Test Success
• RTO Achievement
• RPO Achievement
• Service Availability
• WAN Availability
• DR Test Results
• Recovery Time
• Open Continuity Risks
• Critical Single Points of Failure

so that management has a clear picture of actual resilience.

Business continuity works more effectively when it is part of the overall IT management framework.

MSP

Keeps the infrastructure running day to day.

MSSP

It protects against threats and detects incidents.

Business Continuity

Ensures that the business can continue to operate when something gets past the previous levels of protection.

The overall logic is:

From High Availability to Business Resilience

High availability is important, but it is not enough.

A redundant server does not protect against ransomware.

A single, flat network significantly increases the risk of lateral movement in the event of a breach.

A backup does not by itself guarantee fast recovery.

True business resilience requires multiple layers of protection operating in coordination.

Why Business Continuity

Business continuity must not depend on luck

COSMODATA treats Business Continuity as part of an organization's overall technology strategy.

We analyze critical services, identify points of dependency, design alternative scenarios and create the technical and organizational prerequisites for fast recovery.

Because the goal is not simply to restore a system.

The real goal is for the business to keep running.

Stay Operational. Stay Resilient. Keep Business Moving.
