1 Assess your data risks

Identifying potential risks and vulnerabilities that could compromise your data is the first step to secure it. You should conduct a data risk assessment that evaluates the types and sources of data, the sensitivity and value, the regulatory and legal requirements, the current policies and procedures, and potential threats and scenarios. After your assessment, prioritize the areas that need improvement and create a data security plan to address them. This will help ensure your data is protected against any potential threats or scenarios.

2 Encrypt your data

Encryption is one of the most effective ways to protect your data from unauthorized access. This process involves transforming data into a code that can only be read by those who have the key to decrypt it. It's important to encrypt your data both at rest and in transit, when stored on devices or servers, as well as when transferred over the internet or other networks. There are various types of encryption methods and software you can choose from, such as symmetric encryption which uses the same key for encryption and decryption, asymmetric encryption which uses a pair of keys to encrypt and decrypt, hashing which converts data into a fixed-length string that cannot be reversed, and digital signatures which verify the identity and authenticity of the sender and the data.

Implement encryption protocols for both data in transit and data at rest. Utilize strong encryption algorithms to protect sensitive information from unauthorized access.

3 Backup your data

Creating backups of your data is essential to protect against data loss due to a disaster, hardware failure, or human error. You should backup your data regularly and frequently, depending on the rate of change and its importance to your business. Additionally, it's important to test your backups periodically to ensure they are working properly and can be restored if necessary. There are several types of backup solutions and software available, such as cloud backup which stores data remotely on a server or external hard drive backup which stores data on a physical device. Network-attached storage (NAS) backup stores data on a device connected to your local network, while tape backup stores data on magnetic tapes that are both durable and cost-effective.

4 Monitor your data

Monitoring your data is essential to detect and respond to any anomalies or incidents that could put your data security at risk. This entails collecting and analyzing data about the activities and events that occur on your data systems and networks. Continuous and comprehensive monitoring should be done using different metrics and indicators that reflect the performance and health of your data. Additionally, alerts and notifications should be set up to inform you of any suspicious or abnormal behavior or changes in your data. There are various types of monitoring tools and software you can use, depending on your data complexity and objectives. These include data quality monitoring, which checks accuracy, completeness, and consistency; data access monitoring, which tracks who, when, and how your data is accessed or modified; data breach monitoring, which identifies and reports any unauthorized or malicious attempts to access or steal your data; as well as data recovery monitoring, which verifies and measures the effectiveness and speed of your backup and restoration processes.

This is easier said than done in large enterprises. Data usually does not stay within one system. Operational or analytical data are often kept separately. Whether it is in your business warehouse or data lake (or mesh), the operational systems for process support are just one source to get to your data. It's important to have a complete and consistent data-usage overview in order to effectively monitor where your data goes (is used, altered). And do not limit data to IT systems, a printout left in the train is as dangerous as an uncareful forwarded email. Hence, Section 5 is absolutely necessary: do not forget to train your staff.

5 Educate your staff

Educating your staff is essential to ensure they follow the best practices and standards for data security. It is important to provide them with the knowledge and skills necessary to handle and protect data properly and responsibly. Regular and consistent education, tailored to each person's learning style, is key. Additionally, you should evaluate and update your data security training program periodically to make sure it is relevant and effective. Topics and tips to include in your program are the importance of data security for your business and customers, the types and levels of risks and threats, the policies and procedures in place, the tools and software used, as well as best practices like using strong passwords, avoiding phishing emails, locking devices, and reporting issues.
