The need for customer data protection grows as we continue into the digital renaissance, in which more customers are moving to online purchasing methods. This need is only furthered by the uptick in cyber attacks targeting customer data.
To maintain your business reputation and build trust with your clients, implement these best practices for securely managing customer data.
Combined with strategies to safeguard against cyber-attacks, you can confidently grow your brand, increase revenue, and keep customer data safe.
1. Implement Strong Access Controls
Access controls are systems that secure sensitive data and only allow access to authorized personnel. It’s critical to keep your data out of black hat hackers’ hands.
There are two types of access controls: physical and logical. Physical controls limit in-person access to sensitive areas, like server rooms. Logical controls restrict network and computer access.
Strong physical and logical access controls include multi-factor authentication, biometric verification, and password regulations.
Lastly, always keep Role-Based Access Control (RBAC) in mind. RBAC assigns access controls depending on employee roles in the organization. So, employees only have access to the networks or physical locations necessary for their job functions. By utilizing RBAC, you can limit access to sensitive information across the board.
2. Encrypt Data at Rest and in Transit
Encryption is the process of turning readable data into encrypted and unreadable data. The only way to read the data is to have the matching encryption key, which turns the data back into its original, readable format.
Encrypting data both at rest and in transit is crucial for protecting sensitive information from unauthorized access. Using a KYC checklist can ensure that encryption protocols are properly implemented and maintained.
Even if malicious parties access sensitive customer data, they won’t be able to make anything of it without the authorized encryption key. In other words, you can encrypt and hide key customer data like credit card information even if there is a breach.
There are various tools you can use to encrypt your data. AES (Advanced Encryption Standard), TLS (Transport Layer Security), and encryption software like Bitlocker are great options to integrate.
3. Regularly Update and Patch Systems
Black hat hackers, or cyber criminals, mainly exploit vulnerabilities in outdated software and systems to access customer data. Updates are there to patch vulnerabilities and prevent customers from being exploited by emerging threats.
You must regularly update your software and patch systems to stay ahead of cybercriminals and their exploits.
Fortunately, keeping updated is easy when you utilize built-in software protection tools.
Enabling automated updates ensures immediate updates and patch installations. Patch scheduling, similar to automatic updates, schedules and prioritizes critical patch updates.
Lastly, you can also utilize patch testing to test your systems against unauthorized access. This way you can control the outcome and check for any possible exploits before you launch your software and system.
4. Conduct Regular Security Audits and Assessments
Security audits involve comprehensive evaluations of your security policies, practices, and controls. These audits identify possible vulnerabilities in a controlled environment, which you can then fix before going live with your systems.
To conduct a thorough security audit: identify the areas that need to be audited; identify possible threats and system exploits; thoroughly test your current security policies and controls; and use this data to inform and guide future system updates.
There’s also a variety of tools for you to use when performing audits, like Nessus, Qualys, and MSSPs.
Nessus is a popular and highly effective vulnerability scanner, Qualys is a vulnerability monitoring system, and MSSPs (Managed Security Service Providers) provide in-depth security assessments.
Additionally, if you are preparing for SOC 2 readiness, integrating these tools and practices into your audit process will help ensure that your systems meet the stringent security requirements of SOC 2 compliance
5. Train Employees on Data Security Practices
Data protection strategies won’t be as effective if employees don’t understand data security, because employees are often the first line of defense against data breaches.
By providing proper data security training, employees are more likely to make informed choices that protect sensitive information.
Raise awareness of the following topics:
- Phishing Scams: Teach employees to recognize phishing scams, especially email phishing scams, and how to respond and report them.
- Password Security: Teach employees how to utilize strong passwords, password managers, and multi-factor authentication for better password security.
- Incident Reports: Discuss how to report security breach issues to relevant parties.
- Data Handling: Offer guidelines on how to handle and transmit data securely.
There are a variety of interactive workshops and e-learning courses to choose from, each with unique benefits.
Interactive workshops are more engaging and provide hands-on experience. On the other hand, online courses allow employees to progress at their own pace. They can also return to their materials whenever they need a refresher.
6. Implement a Robust Incident Response Plan
Lastly, implement a robust incident response plan. An incident response plan outlines the procedures for detecting, responding to, and recovering from security incidents. A comprehensive response plan can minimize damage, reduce downtime, and ensure compliance.
To create your response plan, form a response team that manages cybersecurity issues. Define the roles and duties of each member and work together to create a plan for removing and recovering from exploits.
Continue to test and update your response plan to manage new security threats. Working with cyber protection firms is also a great way to identify gaps and areas for improvement, ensuring the plan remains relevant and efficient.
Conclusion
Protecting customer data is essential for any modern business. You significantly enhance your business’s customer data security posture by implementing strong access controls, encrypting data, regularly updating systems, conducting security audits, training employees, and having a robust incident response plan.
Remember, cyber security requires continuous learning and improvement. So, stay updated on emerging trends, threats, and best practices.
