Small and medium-sized businesses (SMBs) are increasingly being targeted by threat actors, due to their perceived lack of security measures. As SMBs work to protect themselves, they are turning to the Australian Cyber Security Centre (ACSC)’s Essential 8 Maturity Model for help. This framework offers guidance on how thoroughly prepared your business is to handle cyber threats.
What Are the Essential 8 Strategies?
The Essential 8 is a set of cyber security practices designed to prevent cyber threats, limit damage if an attack occurs, and make recovery easier. They include:
- Application Control– Limit which applications can run on a network, to block harmful or unnecessary software.
- Patch Applications– Ensure that applications are updated regularly to fix known vulnerabilities.
- Configure Microsoft Office Macro Settings– Control the use of macros in Microsoft Office applications to prevent malware infection.
- User Application Hardening– Disable risky web browser features, like Flash and Java, that can introduce vulnerabilities.
- Restrict Administrative Privileges– Limit administrative rights to minimise the risk of malware spreading within the network.
- Patch Operating Systems– Keep operating systems updated to address security vulnerabilities.
- Multi-Factor Authentication (MFA)– Require multiple forms of verification before granting access to systems.
- Daily Backups– Ensure data is backed up daily and is readily available for recovery in case of an incident.
Understanding the Essential 8 Maturity Model
Along with the strategies provided above, the Essential 8 also includes a Maturity Model to help you determine how secure your SMB is. It is separated into four levels:
- Maturity Level 0: Insufficient cyber security measures are implemented. Your business is vulnerable and at high risk of exploitation.
- Maturity Level 1: Basic protections are in place, addressing the most common threats. However, security is limited and may only prevent the most basic attacks.
- Maturity Level 2: Intermediate protections capable of mitigating more complex attacks. Security practices are more robust, but gaps may still exist.
- Maturity Level 3: Comprehensive cyber security measures designed to defend against advanced and targeted attacks. This level represents a business with mature, sophisticated security defenses.
Which Essential 8 Maturity Level Is Right for Your SMB?
To understand how the Essential 8 Maturity Model applies to your SMB, and which level you should aim for, you will need to consider the following:
Maturity Level 1: Basic Protection for Most Businesses
For many SMBs, Level 1 is a realistic starting point. This level provides essential protection against common cyber threats, addressing vulnerabilities that could be exploited by less sophisticated attackers.
- SMBs with extremely limited budgets and resources
- Businesses without specific regulatory or compliance requirements
- Businesses looking to build a basic foundation for cyber security before advancing to more complex measures
- Protection against everyday cyber risks like phishing and malware
- Improved cybersecurity posture at a low investment threshold
Maturity Level 2: Intermediate Protection for SMBs in Regulated Industries
Maturity Level 2 provides stronger security controls, and should be the goal of every business that has the resources and/or is in a regulated industry. At this level, you have addressed basic risks and have additional protections to defend against more sophisticated threats.
- Businesses in industries with regulatory compliance requirements.
- SMBs managing sensitive data, such as personal or financial information
- Companies that have previously experienced a cyber-attack and need stronger defenses
- Enhanced protection against more complex attacks
- Helps fulfill compliance obligations in regulated industries
Maturity Level 3: Advanced Protection for High-Risk Environments
Level 3 is the highest standard of protection. At this level, you have taken every possible step to prevent cyber-attacks, including targeted ones. Level 3 is ideal for high-value targets, or businesses with particularly advanced security and compliance standards.
- SMBs that handle highly sensitive or valuable data
- Businesses in industries with strict data security compliance mandates
- Businesses at high risk of targeted attacks (e.g. government contractors)
- Proactive defence against the most advanced cyber threats
- Best possible alignment with regulatory compliance and data protection standards
Implementing the Essential 8 in Your SMB
- Perform an Analysis: Assess your current security posture to identify gaps between your existing measures and the desired maturity level.
- Take an Incremental Approach: Begin with foundational practices, then slowly implement more advanced controls.
- Focus on High-Impact Areas: Strategies like MFA, daily backups, and patching can significantly improve your security without high investments. Prioritise these inexpensive solutions first.
- Partner with Experts: Many SMB slack the in-house resources to reach higher maturity levels. A Managed Service Provider (MSP) can assist with implementation and monitoring of Essential 8 controls.
