Ransomware attacks have been on the rise over the past few years, threatening individuals and businesses alike. By encrypting files and demanding payment for decryption, ransomware has cost victims billions of dollars globally. However, there are effective measures you can take to protect yourself and your organization from these malicious threats. 

Data Backups: The First Line of Defense

Data backups are the cornerstone of any Ransomware Protection strategy. By maintaining clean, current backups disconnected from the network, organizations can avoid paying ransoms and regain access to data even after an infection. Here are some tips for implementing an effective backup solution:

- Backup regularly and store multiple versions: Back up critical systems and files daily with versioning to allow restoration to any point before an attack. Weekly or monthly backups of non-critical assets are also recommended.

- Use the 3-2-1 method: Maintain 3 copies of backups, using 2 different formats (e.g. physical drives and cloud) with 1 copy stored offsite for safety in case of a local disaster or cyber incident.

- Test regular restoration: Test restoring from backups at least quarterly to validate integrity and usability. Address any issues immediately.

- air-gap or store offline: Completely disconnect or keep one backup copy offline and isolated to deny ransomware access for encryption. Consider security vaults or cloud storage.

- Encrypt sensitive data: Utilize encryption when backing up highly sensitive files to restrict unauthorized viewing if backups are lost or stolen.

- Control access tightly: Limit who can access and modify backups using authentication and authorization controls to prevent tampering or cyber attacks against backups.

- Automate for consistency: Use backup software or services that automate the entire process with versioning for ease and ensuring regular, complete backups are maintained.

Keeping clean, recoverable backups is the surest way to deny ransomware its leverage over victims. Testing restoration frequently validates its protection. Combined with other security controls, backups defeat the ransomware threat by eliminating payment needs.

Addressing Recovery and Resilience

Even with strong prevention efforts, the evolving threat landscape means some attacks may still succeed. It is critical to develop an incident response plan and build resilience.

Plan Ahead for Any Intrusion

Establish guidelines for detecting an intrusion, isolating affected systems, documenting impacts and enacting recovery procedures, including steps for after remediation like working with legal counsel.

Develop a Communication Strategy

Prepare messages and channels for notifying key stakeholders like customers, suppliers and regulators of any incidents, including mitigation efforts, investigation status updates and return to normal operations timing.

Bolster Cyber Insurance Coverage

Evaluate cyber insurance policies providing coverage for costs associated with ransom demands, lost income during downtime, PR needs and other potential incident response expenses.

Conduct Tabletop Exercises

Runscenarios where senior leaders activate the response plan for imaginary incidents to test readiness, procedures and roles as preparation for real events. Address gaps with revisions.
