Australian Cyber Security Centre Framework
The Australian Cyber Security Centre created this framework. It helps protect businesses from cyber threats. The framework includes eight key security controls.
These controls work together to reduce cyber risks. They protect your critical data and systems. Additionally, they help you respond faster to security incidents.
The Eight Essential Controls
The Essential Eight framework covers key security areas. Each control addresses specific cyber threats.
1. Application Control
Only approved programs can run on your systems. This prevents malicious software from executing.
• Create an approved application list
• Block unapproved programs automatically
• Review and update the list regularly
Furthermore, application control stops many malware attacks. It’s your first line of defense.
2. Patch Applications
Keep all software up to date. Cyber criminals exploit known vulnerabilities.
• Install security patches within 48 hours
• Prioritize critical vulnerabilities first
• Automate patching where possible
Meanwhile, unpatched software creates easy targets. Regular updates close security gaps quickly.
3. Configure Microsoft Office Macros
Macros can contain dangerous code. Control how they run.
• Disable macros from the internet
• Only allow signed macros
• Train staff about macro risks
Consequently, macro settings prevent many email attacks. This simple step blocks common threats.
4. User Application Hardening
Reduce attack surfaces in common programs. Disable unnecessary features.
• Block Flash and Java content
• Disable web browser ads
• Remove unused plugins
Therefore, hardened applications are harder to exploit. They offer fewer entry points for attackers.
5. Restrict Administrative Privileges
Limit who has admin access. Not everyone needs full system control.
• Use separate admin accounts
• Apply least privilege principle
• Monitor admin activity closely
Additionally, restricted privileges contain damage. If one account is compromised, the impact is limited.
6. Patch Operating Systems
Update Windows, Mac, and Linux systems. Operating systems are prime targets.
• Install OS updates within 48 hours
• Enable automatic updates
• Replace unsupported systems
However, old systems can’t be fully protected. Replace them when support ends.
7. Multi-Factor Authentication
Require two forms of identification. Passwords alone aren’t enough.
• Enable MFA for all users
• Use authenticator apps
• Protect admin accounts especially
Furthermore, MFA stops most credential theft. Even stolen passwords won’t grant access.
8. Regular Backups
Keep copies of important data. Backups are your safety net.
• Back up data daily
• Store backups offline
• Test restoration regularly
Meanwhile, good backups enable quick recovery. You can restore systems after ransomware attacks.
Why These Controls Matter
The Essential Eight work together effectively. They address the most common attack methods.
Proven Protection
These controls stop most cyber attacks. The Australian government developed them based on real threats.
• Block 85% of attacks with full implementation
• Reduce cyber incident costs significantly
• Meet compliance requirements easily
Additionally, many insurance companies require these controls. They’re becoming industry standard.
Start Implementing Today
You don’t need to implement everything at once. Start with the most critical controls first.
• Begin with application control and patching
• Add MFA for all accounts
• Set up regular backups immediately
Consequently, each control you implement improves security. Progress matters more than perfection.
Get Expert Help
Implementing these controls can be complex. Professional guidance ensures proper setup.
Furthermore, experts can assess your current security. They identify gaps and prioritize improvements. Therefore, consider working with certified security professionals.
