Baltimore, Albany, Lake City, New Orleans—these are just a handful of cities that have recently suffered a ransomware attack. One cybersecurity firm reports 140 attacks in just the last year targeting state and local governments and public health care providers. Odds are strong that the number is much higher. Organizations like to keep news of cyber incidents close to the vest.
Ransomware attacks are particularly menacing to state and local governments. They must ensure that vital services such as public safety remain available 24×7, while they’re seeing their resources stretched increasingly thin. These organizations make ideal attack targets for two reasons:
- Cybercriminals understand that state and local governments must be “always on duty” and would need to resolve a ransom issue quickly
- State and local cyber defenses may not be as robust as Federal agencies and large corporate enterprises.
The Need for Both Offense and Defense
The threat of a ransomware attack necessitates not only a strong defense, but an equally strong offense. We often see organizations focus heavily on protecting entry points to data and ensuring data is backed up frequently. These are important steps. But it is equally important that state and local governments can get back on their feet after an attack, and do so quickly. There is no guarantee that you can secure every entry point. And data backup is useful only if it is accessible when you need it the most.
Ransomware attacks can put stress on existing data-protection infrastructure built on legacy architectures, such as disk and tape, more than expected. For organizations already struggling to meet recovery service-level agreements, a ransomware attack can exacerbate the situation with additional downtime. Additionally, backup systems and data can be compromised, requiring reinstallation and reconfiguration of backup solutions before beginning data recovery. Windows and Linux systems are both at risk.
Reducing Threats to the Data Protection Infrastructure
To reduce the threats posed by ransomware to data protection infrastructure, create read-only snapshots of backup data and associated metadata catalogs after performing a full backup. You can recover data directly from these snapshots, mitigating the effects of ransomware.
Pure Storage® offers SafeMode snapshots for FlashBlade™ systems. A built-in feature, SafeMode enables you to create these snapshots. In addition to addressing ransomware, they provide protection against rogue admins, because snapshots are protected natively by FlashBlade, outside admin control.
Ransomware can’t delete, modify, or encrypt SafeMode snapshots. They enable rapid recovery via a massively parallel architecture and elastic performance that scales with data to speed backup.
With SafeMode, recovering data following a ransomware attack is a four-step process:
- Delete compromised data.
- Reinstall backup software.
- Point backup software at metadata catalog in SafeMode snapshot.
- Begin recovery.
With a constantly evolving threat climate, ransomware protection or recovery will never be as easy as 1-2-3. But with daily vigilance and thorough preparation, state and local governments can thwart attacks or significantly mitigate their effects.
