Safeguarding Success: The Ultimate Guide to Protecting Your Company's Sensitive Data

In today's digitally driven world, where information is readily accessible, protecting your company’s sensitive data has become paramount. From customer details to financial records, a data leak can lead to financial losses, legal consequences, and irreparable damage to your reputation. 

Businesses in Australia must adopt robust measures to protect this data from increasingly sophisticated cyber threats. This requires a holistic approach that combines consulting with an IT consultant for security, employee education, strong security protocols, and a culture of vigilance.

Why Is Protecting Your Company's Sensitive Data Important?

You may think a data breach won't happen to your company but cyberattacks are increasing every year in Australia. It's not just big businesses at risk; smaller businesses face cyber threats as well. According to the Australian Cyber Security Centre (ACSC) almost 94,000 reports were made to law enforcement through ReportCyber – around one every 6 minutes - in FY2022-2023.

The impact of data loss can be devastating. The average cost of a data breach in Australia was AUD $3.35 million in 2022, a substantial sum that most companies can't afford. Plus, it can take years to recover from the damage to a company’s reputation.

Steps to Protecting Your Company’s Sensitive Data

The goal of data protection is to keep sensitive data safe from both internal and external threats. This means securing all types of information including customer details, employee information, financial records, and intellectual property. There's no "set and forget" solution to data security. You need multiple lines of defence to stay safe. Here are some practices to protect your data:

Understanding Different Types of Data

Not all data carries the same risk. A good first step is classifying your information based on its sensitivity. Each category has its vulnerabilities and regulations, so your protective measures must be tailored. This could include extra encryption layers, limiting user access, or anonymising datasets when appropriate. Some examples of sensitive data include:

Customer PII

As a customer, your personally identifiable information (PII) such as names, addresses, contact information, and government ID numbers are subject to regulation through laws like Australia’s Privacy Act and the GDPR in Europe. Ensure that your PII is handled securely and complies with these regulations.

Financial Information

Your financial information, including bank details, credit card numbers, and financial transactions, is subject to security requirements outlined by the Payment Card Industry Data Security Standard (PCI DSS). This standard dictates the necessary security measures to be followed when handling card information, ensuring the protection of your financial data.

Health Information

When it comes to your health information, strict regulations are in place to protect sensitive health data (PHI). In Australia, the Privacy Act covers the secure handling of your health information and safeguards your privacy.

Proprietary Information

Maintain the confidentiality of proprietary information such as trade secrets, intellectual property, and internal financial data to maintain a competitive advantage. As a user, you can ensure that proper measures are in place to protect this proprietary information from unauthorised access or disclosure.

Strengthening Your Passwords and Authentication

We all know how to use strong passwords, but most people fall short when creating one. Most data breaches involve easily guessed or stolen passwords. Use these tips to improve yours:

Make It Lengthy

Create longer passwords as they are generally more difficult to crack. Aim for passwords with at least 12 characters whenever possible. When you increase the length of your password, you strengthen its security against potential threats and unauthorised access.

Use Mixed Characters

When setting up passwords, ensure to include a mix of upper and lowercase letters, numbers, and symbols to create stronger combinations. Consider using passphrases, which are strings of unrelated words, as they are more challenging to guess compared to single-word passwords. This enhances the complexity of your passwords and bolsters your online security.

No Personal Ties

Avoid using passwords with personal ties such as dates, names, or other easily accessible information found on social media. Instead, consider using password managers to generate strong, random passwords for you. These tools not only create secure passwords but also eliminate the need for you to remember them. 

Implement Multi-factor Authentication (MFA)

For an added layer of security, it is advisable to implement Multi-factor Authentication (MFA) wherever possible. Making MFA mandatory means requiring a secondary code (which can be received via phone, email, etc.) in addition to your password when logging into an account. 

This adds an extra level of protection to safeguard your sensitive data, even in situations where one authentication method may be compromised. Implementing MFA is a proactive measure to enhance the security of your online accounts and minimise the risk of unauthorised access.

Securing Your Devices and Network

Protecting company data starts with keeping your devices and network secure. This means paying attention to both physical and digital threats. Businesses must implement security strategies that address data handling practices across their entire data lifecycle.

Implementing Firewall Protection

Firewall protection helps in any security plan, especially when using public Wi-Fi. Firewalls act as a barrier between your devices and malicious actors looking to exploit security gaps. Unstructured data, such as that found in emails and documents, also requires protection.

Protecting Data in Transit

Data transmitted between devices needs robust protection through strong encryption. Utilise SSL/TLS and HTTPS for protection against hackers. Data security must encompass the encryption of both data in motion as well as at rest. This involves using symmetric and asymmetric encryption, particularly through network protocols like SSL/TLS and HTTPS.

Encrypting Sensitive Data at Rest

This refers to the data stored on your computers and in the cloud. Secure your databases, files, and even the hard drives of digital copiers. The hard drives of digital copiers often contain highly sensitive data and are vulnerable to hacking or physical removal for malicious data retrieval. Encrypting this data with tools can prevent unauthorised access. Strong encryption ensures only those with encryption keys can read and work with sensitive data.

Application-Level Encryption

Application-level encryption can also further protect your data whether at rest, in use, or in transit. This is especially important for businesses handling personally identifiable information like phone numbers and social security numbers. 

Regular Backups for Data Protection

Imagine losing important data because a hard drive failed, or your system is hit by ransomware. This nightmare scenario highlights why regular backups are a must for data protection. Offsite backups and cloud-based solutions ensure quick recovery, even in a worst-case scenario. 

Remember: three backups are better than two, and having those stored in diverse locations (onsite, offsite, cloud) is your best protection against irreversible data loss.

Cultivating Employee Awareness

It's alarming, but some data breaches are caused by human error. We humans are the weakest link, making employee education as important as technology when it comes to data security. This includes educating them on the importance of protecting business data, building customer trust, and adhering to data protection regulations.

Data breaches can easily happen due to unintentional errors, negligence, or even just plain bad luck on the part of your staff. Train your employees to be vigilant. This encourages a “culture of security” where everyone plays a part in protecting company data. Understanding data and how it is used within the company is also an important aspect of this culture.

Prioritise these practices in your training:

Recognising and Reporting Phishing Attempts

Educate your team about the various forms of phishing, including email phishing, SMS phishing, and social engineering tactics to equip them with the knowledge to identify and report potential phishing attempts. Raise awareness about these techniques because phishing attacks are a prevalent method used by hackers to gain unauthorised access to systems and sensitive data.

Using Secure Communication Channels

Ensure the implementation of secure instant messaging apps with access limited to accounts under your domain rather than using public-facing free alternatives that may have weaker security profiles. 

If your staff members are working remotely, ensure that they utilise a VPN to secure their communication and data transmission. This effectively bolsters the protection of sensitive information and reduces the risk of unauthorised access.

Understanding Password Security

Reinforce the importance of good password hygiene among your team, emphasising the prohibition of writing down passwords and highlighting the dangers of sharing sensitive information through unencrypted channels. 

Educate your staff about the risks associated with sharing data through insecure platforms and stress the need for secure practices to protect sensitive information from being compromised.

Clear Desk Policy

Enforce a clear desk policy to ensure that no papers containing sensitive data are left unattended or lying around. Incorporating measures such as a clear desk policy demonstrates the commitment to making significant efforts to maintain security and confidentiality as an integral part of the daily workflow. 

Implement Data Access Control Systems

Utilise Role-Based or Attribute-Based access control (RBAC/ABAC) that adheres to the “principle of least privilege” to limit internal vulnerabilities where unauthorised access or mishandling of data may occur. Make security an ongoing conversation, not just a one-time training session to foster a culture of vigilance and proactive protection of sensitive data. 

Evaluating Third-Party Vendor Risks

We often focus on our internal security while neglecting the risks from third-party vendors. Knowing the full cyber footprint of each vendor connected to your organisation is important. 

Tiering those vendors based on how much sensitive data they have access to is even more critical. This includes cloud storage providers, software vendors, and anyone who accesses your data.

Data Processing Agreements Are Critical

Ensure all third-party partners have data processing agreements in place. Conduct thorough due diligence on vendors before granting them access to your systems. This is especially crucial in light of incidents like the 2020 SolarWinds breach, where a supply chain vulnerability led to the compromise of numerous organisations, including government agencies.

Examine your partners’ security practices closely and request their data breach incident reports. Transparency is key when entrusting others with your data.

Regular Review & Updating Practices

The cybersecurity landscape evolves quickly. Staying on top of software updates, security audits, and staff training ensures you’re not leaving your company exposed. Data privacy is an ongoing concern, especially with the rise of technologies like machine learning, which often rely on large datasets.

Ongoing Maintenance

Treat data security like an ongoing journey, not a destination you reach and then forget about. New threats arise constantly. Update software to patch vulnerabilities, re-evaluate your vendor relationships periodically, and adapt your training to include the latest tactics used by hackers. 

Regulations define sensitive data broadly. It includes names, addresses, financial data, biometric data, and online identifiers. Some data, such as sexual orientation, is heavily regulated.
