Strengthening Cybersecurity: The Essential 8 Practices


ACSC Essential 8

In today's rapidly evolving digital landscape, the importance of robust cybersecurity measures cannot be overstated. As businesses increasingly rely on technology to streamline operations and enhance productivity, the risk of cyber threats continues to grow. ViridianIT understands the significance of safeguarding sensitive information and maintaining the integrity of its systems. In this post, we will explore the Essential 8 cybersecurity practices that can fortify your defenses against a myriad of cyber threats.

1. Patch Applications:

One of the most common entry points for cyber attackers is exploiting vulnerabilities in software applications. Keeping applications up-to-date with the latest security patches is crucial in preventing these vulnerabilities from being exploited. Everyone should implement a rigorous patch management system to ensure that all applications are promptly updated, minimizing the risk of security breaches.

2. Patch Operating Systems:

Just as with applications, operating systems are prime targets for cyber threats. Regularly updating and patching operating systems is essential to address known vulnerabilities and enhance overall system security. A comprehensive strategy for monitoring, testing, and deploying OS patches promptly across all devices in the network should be implemented.

3. Multi-Factor Authentication (MFA):

Multi-factor authentication adds an additional layer of security beyond passwords. By requiring users to provide multiple forms of identification, such as a password and a one-time code sent to their mobile device, MFA significantly reduces the risk of unauthorized access. Implementing MFA ensures that even if passwords are compromised, attackers face an additional barrier to entry.

4. Restrict Administrative Privileges:

Minimizing the number of users with administrative privileges helps mitigate the potential impact of a security breach. Implementing the principle of least privilege, ensuring that users have only the access necessary for their roles. This restricts the ability of attackers to move laterally within the network and limits the damage they can inflict.

5. Application Control:

Managing and controlling the use of applications is essential for maintaining a secure environment. By whitelisting approved applications and blacklisting unauthorized ones, you can prevent the execution of malicious software and maintain a more controlled and secure computing environment.

6. Restrict Microsoft Office Macros:

Malicious macros embedded in Microsoft Office documents are a common vector for malware attacks. You should consider disabling unnecessary macros and enforcing strong security policies for the use of macros to reduce the risk of malware infiltration through this avenue.

7. User Application Hardening:

Educating and empowering end-users is crucial for building a resilient cybersecurity posture. Regular training to employees should be provided on best practices, security awareness, and the potential risks associated with various applications. By fostering a culture of cybersecurity awareness, the organization can create a human firewall against cyber threats.

8. Regular Backups:

In the event of a security incident, having regularly updated backups is essential for quick recovery and minimizing data loss. A robust backup strategy is a requirement, including automated backups of critical data, periodic testing of backup restoration processes, and storing backups in a secure, offsite location.


By adopting and consistently implementing these Essential 8 cybersecurity practices, ViridianIT can significantly enhance your resilience against the ever-evolving threat landscape. Strengthening your organization's security posture requires a holistic approach that encompasses technology, policies, and user education.
