Defenses against cyber threats

For Businesses

In today’s digital age, cybersecurity is of paramount importance for businesses of all sizes. The CERT NZ Top 10 Critical Controls is a set of best practices designed to bolster your organisation’s defenses against cyber threats. By adhering to these controls, you can enhance your cybersecurity posture and better protect your business. Let’s take a closer look at each control and understand why they are crucial.


Top 10 Critical Controls

Patch your software and systems

Regularly updating and patching your software and systems is vital to close security vulnerabilities. Failure to do so can leave your organization exposed to known threats.

Implement multi-factor authentication and verification

Multi-factor authentication adds an extra layer of security by requiring users to provide multiple forms of verification, reducing the risk of unauthorized access.

Provide and use a password manager

Password managers help generate and store complex, unique passwords, reducing the risk of password-related breaches.

Configure logging and alerting

Properly configured logging and alerting systems can help you detect and respond to security incidents in real-time, minimizing potential damage.

Asset Lifecycle Management

Understanding and managing the lifecycle of your assets ensures that you have control over all devices and software, reducing the risk of unaccounted vulnerabilities.

Implement and test backups

Regularly backing up your data and systems is your safety net in case of a cyberattack or data loss. Regular testing ensures data recovery when needed.

Implement Application Control

Controlling the applications running on your systems helps prevent unauthorized software and malware from compromising your environment.

Enforce the principle of least privilege

Limiting user access to only what is necessary minimizes the risk of insider threats and unauthorized system changes.

Implement network segmentation

Separating your network into segments can contain and mitigate the impact of a security breach, preventing lateral movement by attackers.

Set secure defaults for macros

Secure macro settings reduce the risk of malicious code execution in documents and emails.

Following these critical controls is essential for your business’s security. They not only help protect sensitive data and systems but also safeguard your reputation and financial well-being.
