8 Data Security Best Practices to Prevent Breaches and Protect Your Data

Data breaches can seriously harm a company’s reputation, break customer trust and lead to costly financial losses. Investing in the right data security software and protecting sensitive information can help to ensure that your business stays secure and runs smoothly.

In this article, you'll find practical tips for improving data security practices, including strong passwords, encryption, employee training and regular software updates.

Data is the lifeline of any business and ensuring data security is vital for protecting what matters most. Safeguarding digital information from unauthorised access and breaches is essential for maintaining customer trust, securing intellectual property and ensuring smooth operations. Let’s take a closer look at why data security is imperative for your organisation.

Data breaches are expensive. The financial fallout includes fines, legal fees and the costs of responding to and preventing future incidents. Beyond the immediate financial impact, breaches can damage your organisation's reputation and erode customer trust. This loss of trust can lead to decreased sales and a damaged brand image that may take years to restore.

• Customer trust and brand reputation: When a data breach occurs, personal information of customers — such as names, addresses and financial details — can be exposed. This can lead to identity theft and other forms of fraud. When customers feel their data is not secure, they are less likely to continue to do business with the organisation. Maintaining robust data security posture management is essential for preserving customer trust and brand reputation.
• Disruption to business operations: Data security incidents can compromise systems, which can lead to downtime, halt productivity and impact revenue. Critical business data can be lost or corrupted, causing further delays and operational issues. Data security helps maintain business operations' continuity and prevents costly disruptions.
• Protecting sensitive information: Organisations manage a lot of sensitive information, including customer data, financial records and intellectual property. Protecting this information from unauthorised access and breaches is crucial for meeting legal and regulatory requirements. Data security measures keep sensitive information confidential and secure, safeguarding the organisation’s assets and maintaining compliance with industry standards.

These essential steps help safeguard sensitive information, prevent unauthorised access and protect against data loss. Here’s a rundown of the top practices every organisation should follow to stay secure.

• Creating strong passwords: One of the fundamental practices for data security is creating strong passwords. A strong password should be at least 12 characters long and include a mix of uppercase and lowercase letters, numbers and symbols. Avoid using personal information, such as your name or birthdate, as part of your password.
• Unique passwords for each account: Using a different password for each account is crucial. If one password is compromised, it prevents attackers from gaining access to multiple accounts. A password manager can help you to create and remember unique passwords for each account.
• Enabling multi-factor authentication (MFA): Multi-factor authentication adds an extra layer of security by requiring a second form of identification, such as a code sent to your phone, when you log in. Enabling MFA on your accounts reduces the risk of unauthorised access.
• Avoiding personal information in passwords: Using personal information in passwords makes them easier to guess. Make sure your passwords are random and do not include easily obtainable information about you.

• Encryption algorithms: Encryption converts data into a format that unauthorised individuals cannot easily read. Algorithms such as AES-256 or RSA-2048 are commonly used to encrypt sensitive data at rest and in transit.
• Transport layer security (TLS): Implementing Transport Layer Security (TLS) ensures encrypted data is transmitted between your web server and users' browsers. This prevents attackers from intercepting and reading sensitive information.
• Strong encryption keys: Using strong encryption keys and storing them securely is essential for maintaining data security. Regularly rotating encryption keys using tools like Shield: Platform Encryption helps prevent unauthorised access and ensures data remains protected.
• Encrypting data on removable media: Sensitive data stored on removable media, such as USB drives or laptops, should also be encrypted. This protects the data in case the device is lost or stolen.
• Encrypting data sent to third parties or stored in the cloud: Ensure data is encrypted before sending sensitive data to third parties or storing it in the cloud. This adds an extra layer of protection and ensures that the data remains secure even if the provider’s cloud security is compromised.

• The 3-2-1 rule: Implementing the 3-2-1 rule for data backups ensures that you have three copies of your data, stored on two local devices, with one copy kept offsite. This redundancy helps protect your data from loss due to hardware failures, natural disasters or other incidents.
• Secure cloud backup services: Using a reliable and secure cloud backup service for offsite storage provides additional protection for your data. Ensure the cloud service provider encrypts your backups to protect them from unauthorised access.
• Regularly testing backups: Regularly testing your backups ensures that they can be restored successfully during data loss. This practice helps identify any issues with the backup process and ensures that your data is recoverable.
• Encrypting backups: Encrypting your backups is crucial for protecting them from unauthorised access. Store your backup encryption keys securely and rotate them regularly.
• Data retention policy: Establishing a data retention policy helps manage the lifecycle of your data, ensuring that it is kept for the necessary duration and then securely deleted. Adhering to a data retention policy, while implementing data loss prevention solutions like Salesforce Backup, helps minimise the risk of storing outdated or unnecessary sensitive information.

• Importance of data security: It’s crucial to educate employees about the importance of data security and following security measures. Employees should understand the potential risks and consequences of data breaches.
• Regular training sessions: Providing regular training sessions on cloud data security best practices helps employees be informed about the latest threats and how to mitigate them. Topics should include password management, recognising phishing scams and defending against social engineering attacks.
• Clear data security policy: Establish a clear data security policy and ensure all employees know and understand it. The policy should outline the organisation's security measures and employees' responsibilities in protecting sensitive information.
• Incentives and rewards: Offering incentives and rewards to employees who show a commitment to data security management helps build a culture of security awareness. Recognising and rewarding good practices reinforces the importance of protecting data.

• Prompt software updates: Installing software updates promptly is critical for patching security vulnerabilities. Delaying updates can leave systems exposed to attacks that exploit known vulnerabilities.
• Centralised patch management: Using a centralised patch management system can automate the process of updating software and ensure that all systems are up to date with the latest security patches.
• Automatic updates: Enabling automatic updates for data security software helps ensure that systems are always running the latest versions with the latest security fixes. This reduces the risk of vulnerabilities being exploited.
• Testing software updates: Testing software updates in a non-production environment like Salesforce Sandboxes before deploying them to production systems helps identify any issues and ensures that the updates do not disrupt business operations.
• Regularly updated security measures: Ensuring that security measures, such as firewalls and intrusion detection systems, are regularly updated with the latest rules and signatures is essential for maintaining robust security defences.

• Firewalls: Using a firewall to block unauthorised access to the network is a fundamental security measure. Firewalls help prevent attackers from gaining access to sensitive systems and data.
• Anti-virus software: Installing and maintaining anti-virus software helps protect systems from malware and other malicious software. Regularly updating the software ensures it can detect and mitigate the latest threats.
• Software security patches: Keeping software up to date with the latest security patches helps protect against vulnerabilities that attackers may exploit. Regularly applying updates is essential for maintaining system security.
• Strong passwords and two-factor authentication: Using strong passwords and enabling two-factor authentication for all accounts adds additional layers of security. Single Sign-On (SSO) solutions can help to strengthen MFA approaches.
• Employee cybersecurity education: Educating employees about the importance of cybersecurity and best practices helps create a culture of security awareness. Employees should be aware of the latest threats and how to protect against them.

• Regular vulnerability scans: Conducting regular vulnerability scans helps identify potential weaknesses in your systems. These scans can detect vulnerabilities that attackers may exploit and help prioritise remediation efforts.
• Prioritising vulnerabilities: Prioritising vulnerabilities based on their severity and exploitability helps focus efforts on addressing the most critical issues first. This approach ensures that the most significant risks are mitigated promptly.
• Implementing security patches and updates: Implementing security patches and updates to address vulnerabilities is essential for maintaining the security of your systems. Delaying updates can leave systems exposed to attacks.
• Penetration testing: Involving security experts to perform penetration testing helps simulate real-world attacks and identify undiscovered vulnerabilities. Penetration testing provides valuable insights into your security measures' effectiveness and highlights areas for improvement.

• Strong authentication: Using strong authentication methods for database access helps prevent unauthorised access to sensitive data. Implementing multi-factor authentication adds an additional layer of security.
• Data encryption: Data masking or encrypting data at rest and in transit is essential for protecting sensitive database information, using tools like Shield: Database Encryption. This ensures that it remains unreadable even if data is intercepted or accessed without authorisation.
• Role-based access controls: Implementing role-based access controls and permissions or principle of least privilege helps ensure that users only have access to the data they need for their roles. Tools, such as Security Centre, help minimise the risk of unauthorised access to sensitive information.
• Monitoring database activity: Monitoring database activity and detecting suspicious behaviour are crucial for identifying potential security incidents. Implementing logging and alerting mechanisms ensures that any unusual activity is promptly investigated. Salesforce Event Monitoring enhances this by tracking and auditing behaviour, monitoring security and providing insights from event logs.
• Regular updates and patching: Updating database software regularly and patching any known vulnerabilities helps maintain the security of your databases. Ensuring that all software is up to date reduces the risk of exploitation.

Regular software updates, endpoint protection, vulnerability assessments and database security are key elements of a strong data security strategy.
