Data Security Best Practices: Insights from ThunderLabs’s Head of Cyber

Worried a data breach will cripple your business? Find out how you can strengthen your defences with insights from Mark Belfanti.

Did you know that 95% of data breaches involve a human element, such as a compromised identity? (IBM Security)  

This startling statistic underlines the crucial need for robust data security measures within any organisation.  Even the most sophisticated defenses can be bypassed if a clever attacker can trick an employee into clicking the wrong link or revealing sensitive information.  

The consequences can be severe, as recent events demonstrate. Just this year, both Microsoft and Stanford University were breached after attackers used social engineering tactics to gain access to crucial systems. 

The ThunderLabs content team caught up with Mark Belfanti, ThunderLabs’s Head of Cyber, to uncover actionable strategies for protecting organisational data against cyber threats. 



Identify & Protect Critical Data 

Mark stresses the importance of knowing which data is vital to your organisation. Understanding and identifying the “crown jewels” of your information allows you to apply the necessary protective measures effectively. This knowledge forms the bedrock of your security strategy. 



Implement strict access controls

Give users the minimum levels of access or permissions needed to perform their job. This is the principle of least privilege. This means ensuring that data is accessible only to those who absolutely need it for their work. This approach is critical in minimising the risk of data exposure from within. 


Strengthen Identity Protection 

A significant insight from Mark is that the majority of breaches involve compromised identities. Strengthening identity protection through robust password policies, and the adoption of multi-factor authentication (MFA), is crucial in safeguarding against unauthorised access. 



Enforce Cyber Hygiene & Configuration Management 

Maintaining your systems involves more than just setting them up securely. Mark highlights the importance of regular patching, system hardening, and ensuring that systems are configured to run only what is necessary. This discipline in cyber hygiene reduces the attack surface available to hackers. 



Implement Encryption 

Data encryption is a fundamental practice recommended by Mark, especially for devices that may leave the secure environment of your office. Encrypting data ensures that, even in the event of physical theft, the information remains inaccessible to unauthorised users. 



Cultivate a Security Culture  

Developing a culture of security within your organisation is pivotal. Mark points out that social engineering is a common tactic used by hackers. Educating employees on the risks and signs of social engineering attacks is vital in creating a human firewall against these threats. 



Incorporate Security Throughout the Lifecycle 

Security should be a consideration from the very beginning of system design, throughout the building process, and in everyday operations. Mark emphasises the importance of security by design, by build, and by operation, ensuring that security measures are not bypassed or forgotten at any stage. 


Prepare for the Eventuality of a Breach

Finally, Mark advises that organisations should operate under the assumption that a breach will occur. Having a comprehensive incident response plan in place, that is regularly practiced and workshopped,  ensures that you can react swiftly and effectively, minimising damage and restoring operations more quickly. 



Act Now 

Complacency is not an option. The complexity of safeguarding your organisation’s data is unquestionable, but ThunderLabs stands ready to support you.  

Don’t wait for a breach to occur. Proactive steps today can fortify your defences, making your organisation not only tougher but also smarter in the face of cyber threats. Let’s work together to craft a security strategy that defends and adapts, ensuring your resilience in the digital age.
