Too often, security and resilience are lumped together—but the distinction is vital.
While research shows that cybersecurity risk management in Australian financial services firms is improving, cyber resilience still lags behind those firms’ own benchmarks.
Recovery point objective (RPO) is a measure of how old your most recent backup must be in order to enable normal operations to resume in the event of system failure or data loss.
Recovery time objective (RTO) is the time an application, system, or process can be down before it causes significant damage to the business—plus the time spent restoring the application and its data.
Given that cyber-attackers will often strive to encrypt backups as well, the only way to guarantee an RPO is to use WORM storage: write once, ready many. Even with WORM storage, risks still remain. After a recent attack, it took a large US credit bureau seven days to work through its WORM backups to find the most recent uncorrupted version.
