Argentina Turns Disaster Recovery Into a Hard Compliance Test
A new CNC regulation pushes public-sector cyber resilience beyond backups and into measurable recovery targets, testing, and geographically separated infrastructure.
In public-sector security, the most dangerous failure is often not a dramatic breach, but a slow collapse of services after a ransomware hit, hardware loss, or regional outage. Argentina’s Disposición 1/2026, issued by the Centro Nacional de Ciberseguridad, treats that problem as an engineering discipline: systems must be inventoried, ranked by criticality, and paired with recovery plans that can be tested, documented, and audited.
Fast Facts
- Disposición 1/2026 sets technical requirements for continuity planning in the public sector.
- Organisms must maintain a system inventory with dependencies, criticality, RTO, RPO, and recovery priority.
- The regulation distinguishes high, medium, and low criticality, and even low-priority systems need a recovery plan.
- Backup sites must meet infrastructure, connectivity, power, and security requirements, with Tier 3 certification required within 20 months.
- The framework emphasizes drills, playbooks, and documented lessons learned, not just written policies.

The technical shift here is simple to describe and hard to execute: continuity is no longer a vague promise. The rule expects public bodies to map what they run, what each system depends on, how long it can be down, and how much data loss is tolerable. That is classic contingency planning, closely aligned with NIST-style practices that use business impact analysis, recovery objectives, and update cycles to keep plans operational rather than ceremonial.
For defenders, the important part is the chain of evidence. A good inventory forces teams to confront hidden dependencies such as single telecom links, shared identity services, fragile backup jobs, or applications with no clear owner. Once those dependencies are visible, the recovery design becomes more realistic: hot, warm, or cold sites can be matched to actual service importance instead of guesswork.
The regulation is also notable for infrastructure specifics. A separated backup facility, redundant power, independent connectivity, and physical and logical security controls all point to a model where resilience must survive more than one kind of failure. That matters for ransomware in particular, because recovery plans that rely on online backups alone can fail if attackers corrupt both production and backup environments. Offline or otherwise protected backups, plus restoration tests, are the defensive answer.
There is also a governance lesson. Playbooks, approvals, test records, and post-exercise remediation create accountability. In practice, that means a failed tabletop or a slow failover cannot be ignored; it becomes evidence that the recovery design needs work. The most useful part of such regulation is not the document stack, but the pressure it creates to rehearse the response before a crisis does the testing.
Conclusion
The broader lesson is that cyber resilience only matters when it can be measured under stress. By tying continuity to inventories, recovery objectives, tests, and backup-site requirements, Argentina is moving public-sector security toward a model where service survival must be proven, not assumed. That is the real change: disaster recovery has become a technical obligation, and technical obligations are only as strong as the last successful test.
