Regularly audit and review: Regularly audit and review your cloud infrastructure to identify potential vulnerabilities and ensure compliance with security policies and regulations.
These steps will help you build a strong foundation for securing your cloud environment. However, the specific security measures you need will depend on the type of business you operate, the size of your organization, and the level of risk you are willing to accept. It’s important to work with a security professional to develop a tailored security plan that meets your specific needs.
NIST As A Guide
The National Institute of Standards and Technology (NIST) Special Publication 800-61 outlines the Computer Security Incident Handling Guide, which includes a set of steps for handling cyber security incidents.
Preparation: Establish policies, procedures, and a plan for incident response. Identify and prioritize critical assets and personnel, and train and prepare them for potential incidents.
Detection and Analysis: Monitor and detect potential incidents. Analyze the incident to determine its scope and impact.
Containment, Eradication, and Recovery: Contain the incident to prevent further damage. Eradicate the cause of the incident and restore systems to normal operation.
Post-Incident Activity: Review the incident and the response to identify areas for improvement. Update policies and procedures based on lessons learned.
Reporting: Report the incident to appropriate internal and external parties, such as law enforcement, regulatory agencies, and affected parties.
Remediation: Take steps to prevent similar incidents from occurring in the future. Implement controls to reduce the likelihood and impact of future incidents.
These steps provide a framework for organizations to effectively respond to cyber security incidents and minimize the impact on their operations.
