Operational Security

Manage users. Simplify and control access. Safeguard your organisation.

Operational security is the confidence to operate in a dangerous security climate by establishing the controls you need and understanding your maturity from a government framework perspective

What is operational security?

It’s the process of minimising your organisation’s vulnerability to cyber-attacks.

What does an operational threat look like?

There are two basic types of operational security problems:

1. Accidental misconfigurations or breaches.

The most frequent operational issues are not deliberate in nature. They can be as simple as mistyping a value or setting, forgetting a step, or any number of human errors.

2. Deliberate misconfigurations or breaches.

These are planned attacks and vary in their degree of maliciousness. They can be home-grown or initiated from an external entity.

Either problem can result in little/no effect on your organisation, to having a catastrophic impact. With an accidental misconfiguration, there’s every chance that the true extent of the resulting security breach will never even be discovered (only a minor fraction of possible misconfigurations will actually result in a security breach). Naturally, deliberate misconfigurations contrived with malicious intent are more likely to result in a security breach.

Tackling operation threats head on

While we’d love to tell you that we can deliver you full operational security just by applying the right technology, it isn’t so. To be effective, a sound operational security strategy needs process, people and technology working together.  

Security is multi-layered, and each organisation has its own desired security posture. This posture will consist of several solution areas:

Your operational security policy. 

Your policy should be made up of clear guidelines on what your operators are allowed to do, and what they’re not. And if an operator doesn’t have permission for a specific action, a defined escalation path. Your policy will define the responsibilities and authorisation process, as well as any disciplinary actions if there is a breach, and act as a deterrent against deliberate misconfigurations.

Your access control. 

As best practice, deploying a privileges management solution will restrict access to your critical assets and services. Privileges can be added and removed (and these changes audited) so you meet corporate and government standards.

Your access permissions. 

Restrict employee and administrators authorised access to devices, assets or systems to the minimum amount needed for them to do their job. By designing and enforcing a universal directory and implementing access change processes you can significantly reduce risk and security breaches in this area.

Your change management process. 

If you run a network, then you need to create precise processes that define and control how you execute network changes. It’s critical to monitor the state of your hardware, operating system, and configurations. In fact, all changes should be subjected to tightly controlled logging and execution. Logs need to be evaluated and checked for breaches and used to record/show deliberate violations of your operational security policy.

Adding automation to your security.

By automating processes and procedures (namely recurring verification processes) you can overcome human error and reduce mistakes.

We are the first to admit that implementing a comprehensive operational security environment is not an easy one-hit process. Our recommended approach is through a series of planned incremental improvements to the overall operations process. 

Why Fusion5?

Sadly, most companies don’t reach out until they experience a security breach or ransomware attack. If they have no visibility of, or adherence to the government-led compliance guidelines (ASD/Cert NZ) they usually don’t have any processes in place.

This is where we can help.

Our Managed Services are designed to ensure your compliance, minimise operational risk and safeguard you from incurring the significant financial penalties of breaching the guidelines.

Fusion5's sponsored Rapid Security Assessment can identify where you need to make changes and where you are already at a compliance standard in line with Australian Signals Directorate's Essential Eight
