How do you validate and verify data security controls and measures?

Validating and verifying data security controls involves a multi-layer strategy. If using an AWS ecosystem; leverage CloudTrail to capture API activity, and audit trails for security configurations. Invoke AWS Config for recording resource configurations, and maintaining compliance with security policies. Use AWS Inspector, to identify system-level vulnerabilities proactively. KMS can help encrypt keys and enhance data protection. Penetration testing, facilitated by AWS services such as Amazon Inspector and AWS Secrets Manager, can further bolster resilience. The above strategy ensures stringent validation and verification of data security controls and reinforces organizational data integrity and confidentiality.

Validating data security controls involves regular audits, penetration testing, and assessing vulnerabilities. Implement robust authentication, encryption (e.g., AES-256), and access controls like MFA and RBAC. Monitor systems with SIEM for real-time threat detection and response. Educate staff on security protocols and update measures based on evolving threats. These steps ensure comprehensive validation of security measures, mitigating risks and safeguarding sensitive data effectively.

Data security audits are systematic assessments of an organization's information protection measures. Conducted regularly, these audits evaluate the effectiveness of data security controls, ensuring alignment with regulatory requirements and industry best practices. They encompass reviews of access controls, encryption practices, incident response plans, and overall adherence to security policies. Data security audits play a pivotal role in identifying vulnerabilities, mitigating risks, and enhancing the overall confidentiality, integrity, and availability of sensitive information within an organization.

- Process involves testing, auditing, and continuously monitoring the effectiveness of these controls to ensure compliance with security standards and best practices. - Establish baseline security standards based on industry guidelines, such as ISO 27001, NIST Cybersecurity Framework. - Align specific security controls (e.g., encryption, access control, monitoring) with security objectives

Data security assessments are comprehensive evaluations conducted to gauge the strength and effectiveness of an organization's data protection measures. These assessments encompass a thorough analysis of data storage, transmission, and access controls. By scrutinizing encryption practices, user permissions, and adherence to security policies, organizations can identify vulnerabilities and address potential risks. Data security assessments play a pivotal role in fortifying defenses, ensuring compliance with industry regulations, and safeguarding sensitive information from unauthorized access or breaches, thereby bolstering overall data security resilience.

One of the most effective ways to validate data security controls is through a combination of penetration testing and vulnerability scanning. In my experience as an ethical hacker, penetration testing can reveal deep-rooted vulnerabilities that may not be apparent through automated scans alone. For instance, during a penetration test for a financial services company, we discovered a critical flaw in their authentication mechanism that allowed unauthorized access to sensitive customer data. The issue had been missed by regular vulnerability scans but was uncovered through manual testing. By combining different validation techniques, you can ensure that your security measures are both comprehensive and resilient against real-world threats.

There are a number of techniques you can use to validation some of your data security measures, but the most useful is likely running a penetration test to simulate real-world attacks on your data security controls. It allows you to find weakness in your controls before any malicious actors would, as well as assessing the potential impact of those controls and the likelihood of it occurring in the future - it should also provide remediations actions to put in place to mitigate the risk of this weakness from being exploited.

My favorite data security verification tools, and conformance packages installed on SIEMs/SOARs. I have installed conformance packages for NIST Cybersecurity Framework, ISO 27001, and COBIT, and OWASP, PCI DSS, HIPAA. These are Filters, correlation Rules, Reports and network modeling for the subnets and hosts that are under control. For example I was working as Tier IV (SIEM Architect) at an ISP where they were spending 6 months doing a PCI audit, and after I was finished installing and configuring the PCI package it only took about 10 minutes to run the Reports to show PCI conformance. The Engineer in charge of PCI was so happy, to see a 6 month (in the past) job now took 10 minutes.

Modern data security tools have emerged that help organizations assess their data security posture at scale - assessing the control status and configuration of data stores, sensitivity of the data and security of identities with access to the data. These are commonly referred to as data security posture management tools or DSPM.

Adopting best practices in data security validation and verification is crucial for maintaining an effective security posture. One best practice I've found invaluable is conducting validation activities on a regular and consistent basis. For example, in a recent engagement with a healthcare provider, we established a quarterly validation schedule that included both automated scans and manual testing. This regular cadence not only kept the organization compliant with HIPAA regulations but also helped them proactively address security gaps before they could be exploited. Clear communication with stakeholders and a well-documented process are also key to ensuring that everyone is aligned and that improvements are continuously implemented.

Beyond traditional validation methods, consider implementing a continuous feedback loop with your security team and other departments. In one project, I worked with a retail company where we set up a process for employees to report potential security concerns, no matter how minor. This initiative uncovered several previously unknown vulnerabilities and allowed for immediate corrective action. Additionally, using threat intelligence feeds to stay updated on the latest vulnerabilities and attack vectors can provide valuable insights that inform your validation and verification efforts, ensuring they are always aligned with emerging threats.

Unfortunately you can no longer rely on point-in-time assessments to verify and validate your data security measures are sufficient. Without visibility into what data you have, where it lives, who can access it, and how it's being used, your point in time assessments will quickly out of date due to the velocity of data sprawl and permission creep.
