Backups are a crucial part of any organization’s cybersecurity strategy. Without proper backups, losing important data due to cyber attacks, hardware failure or human error can be catastrophic. However, backups also need to be properly secured, as they contain sensitive information that could be targeted by threat actors. Here are some key factors I consider when choosing a cybersecurity strategy to protect my organization’s backups:
Assessing the risk profile
Before implementing security controls, I start by assessing the risk profile of my backups. This involves:
- Identifying what types of data the backups contain, and how sensitive the data is. Customer information, financial records and intellectual property carry higher risk.
- Considering external threats that may target the backups, and vulnerabilities that could be exploited.
- Evaluating the impact on the business if the backups were compromised or made unavailable by ransomware or other attacks. High impact data requires stronger controls.
This risk assessment helps me determine the level of security needed, and where to prioritize my efforts.
Selecting appropriate security controls
With the risk profile in mind, I select technical, administrative and physical controls to apply to the backups:
-
For technical controls, encryption protects backup data both at rest and in transit. Access controls like multi-factor authentication (MFA) for backup tools also add security.
-
Administrative controls include policies for backup management, like requiring unique credentials for backup accounts, and principles of least privilege. Regular backups to alternate media, with offsite storage, improve resilience.
-
Physical security controls restrict access to backup media, servers and data centers. Destroying outdated media also reduces risk of data leaks.
Controls should align to the confidentiality, integrity and availability needs identified in the risk assessment.
Monitoring, testing and improving defenses
Regularly monitoring backup systems for anomalies, testing restoration procedures, and rehearsing incident response helps validate that controls are working as expected.
Penetration testing and red team exercises simulate real attacks to identify vulnerabilities missed in regular audits. I fix any issues discovered to continue strengthening defenses.
Cybersecurity strategies require continual improvement as new threats emerge. I stay up-to-date on industry best practices, and improve security processes to enhance protection.
Obtaining buy-in across the organization
A cybersecurity program only works if properly implemented across departments.
I work with stakeholders in IT, operations, legal, and other groups to get input on the strategy, and gain executive sponsorship.
With alignment at all levels, I can establish the policies, technologies and processes to secure backups against modern threats. Everyone understands their role in protecting this critical data.
Key Takeaways
- Start by assessing risks to the confidentiality, integrity and availability of backups.
- Apply controls like encryption, access restrictions and physical security to match the risk profile.
- Monitor, test and update defenses continuously against evolving threats.
- Involve stakeholders across the business to ensure effective execution of the strategy.
By taking these steps, I can implement a cybersecurity program that reduces our backup risk exposure and safeguards this vital information. Protecting backups is essential for resilience when incidents occur.
