Remote and hybrid work are now standard across Australia and beyond. Teams log in from cloud platforms, shared code repositories, and SaaS tools at all hours.
Cloud workloads, containers, and APIs sit in the middle of this shift. They keep your business running, but they also widen the path for attackers. Misconfigurations, exposed endpoints, and weak access paths are all it takes.
This article focuses on practical moves, not buzzwords. Understand where to start, how to harden what you already run, and where services like web application penetration testing WAPT, secure configuration review, OWASP testing and a structured cyber security audit fit into the picture.
Map Your Attack Surface First
Before you fix anything, you need a clear map. Most breaches start with something nobody realised was online, exposed or still active.
- Spend time building a current inventory. Keep it simple and keep it live. This becomes the backbone for later testing and any cyber security audit work.
- Start with your cloud platforms and SaaS apps. List accounts, subscriptions, regions, and key services. Include smaller “trial” tenants and older projects that might still be connected to production data.
- Then list your container platforms: Kubernetes clusters, Docker hosts, and serverless functions. Note where they run (AWS, Azure, GCP, on-prem), who owns them, and how they are exposed to the internet or partner networks.
- Create an inventory of all APIs: internal, external and third-party. Include mobile backends, partner integrations and legacy endpoints. Many findings in web application penetration testing WAPT come from forgotten or undocumented APIs.
- Finally, do not ignore the people layer. Include laptops, mobiles, home routers, unmanaged tablets and any third-party contractor endpoints. In a remote / hybrid world, these devices are part of your real attack surface whether you document them or not.

Get Cloud Foundations Right
Cloud security fails when everyone assumes someone else is responsible. Get the basics clear, written, and agreed.
- Your team must understand the shared responsibility model for each cloud provider. Make it explicit who owns identity, network controls, logging and patching in each environment.
- Enforce strong identity and access management. Use SSO and MFA everywhere, with role-based access and least privilege. Admin accounts should be few, monitored, and tightly controlled.
- Standardise hardened baselines. A secure configuration review aligned with CIS benchmarks helps you lock down storage, virtual machines, databases and management planes from day one. Repeat that secure configuration review regularly as services change.
- Segment networks and restrict east-west traffic. Do not let a compromise in one workload spread quietly across your estate. Use security groups, network policies, and firewalls with clear rules and ownership.
From the start, turn on logging, monitoring, and centralised alerting. Feed cloud logs into your SIEM so later OWASP testing findings and penetration test results can be correlated with real activity.
Lock Down Containers and Kubernetes
Containers make it easy to ship features fast. They also make it easy to ship vulnerabilities at scale.
- Begin with your images. Use trusted base images only, and scan them for vulnerabilities in your pipeline. Any serious web application penetration testing WAPT engagement will quickly highlight risky or unpatched images.
- Apply least privilege across pods, containers and service accounts. Do not run containers as root unless there is no option. Limit host access and file system permissions so an attacker has less room to move.
- Keep secrets out of code and images. Use a secure vault for API keys, database passwords and certificates. Enforce this in CI/CD so developers follow one simple pattern.
- Enable runtime protection. Watch for abnormal system calls, unexpected processes or unusual outbound connections from containers and nodes. Set thresholds and alerts that are realistic for your workloads.
Finally, patch your container runtimes, orchestrators and add-ons regularly. Combine this with periodic secure configuration review of your clusters so changes over time do not erode earlier controls.
Protect APIs as First-Class Assets
Most modern attacks flow through APIs. Treat them as products, not side effects.
- Maintain a complete API inventory, including “shadow” APIs built for pilots or internal tools. If it accepts requests, it belongs in the register and in scope for OWASP testing and API-focused reviews.
- Protect every API with strong authentication and authorisation. Use modern tokens, short lifetimes and clear scopes. Avoid anonymous or shared credentials wherever possible.
- Validate and sanitise all input. OWASP testing focuses heavily on injection, broken access control and insecure data handling for good reason. Simple checks at input boundaries prevent many high-impact issues.
- Use API gateways for rate limiting, throttling and abuse detection. This protects you against brute force attacks, bots and poor client behaviour.
- Monitor API logs for anomalies: sudden spikes, unusual geographies, failed logins and strange payloads. Feed these logs into the same SIEM used for your cloud and endpoint events to support an end-to-end cyber security audit trail.

Secure Remote and Hybrid Access
If users can reach critical systems from anywhere, you must assume attackers can try from anywhere too.
- Move towards a Zero Trust mindset. Verify users, devices and context every time, rather than trusting a one-off login or network location.
- Require MFA for all remote access and for any admin or privileged action. This includes VPNs, cloud consoles, code repositories and remote management tools.
- Use secure VPN or ZTNA with device posture checks where possible. Block access from outdated operating systems, missing endpoint protection or rooted / jailbroken devices.
- Wherever you can, separate corporate and personal use on endpoints. This might mean managed profiles on mobiles or clear policies plus monitoring on laptops.
- Keep security guidance simple for staff at home. Cover patching, Wi-Fi security, password managers and how to report a suspected incident quickly.
Continuous Monitoring and Incident Response
Security is not a one-off project. It only works if you watch, learn, and adjust.
- Aggregate logs from cloud platforms, containers, endpoints, and APIs into a central SIEM. This makes it easier to line up findings from web application penetration testing WAPT and OWASP testing with real-world activity.
- Define clear incident response playbooks for cloud and container breaches. Spell out who does what in the first hour, and what evidence you need to collect.
- Test these runbooks with tabletop exercises and technical simulations. Use outcomes from each cyber security audit or penetration test to refine your scenarios.
For many organisations, 24/7 Managed Security Services (MSS) are the only practical way to maintain round-the-clock monitoring and response. Providers like Cybernetic Global Intelligence already run SOC operations and managed services for clients across Australia and overseas.
Governance, Compliance and Regular Testing
Technical controls are only half of the story. Governance keeps efforts aligned with risk and regulation.
- Align your program to recognised frameworks such as ISO 27001, NIST CSF and the ACSC Essential Eight. Cybernetic Global Intelligence is an IAF-accredited ISO 27001 certified and PCI DSS QSA firm, so it works with these frameworks every day.
- Run regular penetration tests on cloud apps, APIs and remote access paths. Combine web application penetration testing WAPT and API-specific testing so both browser and machine-to-machine traffic are in scope.
- Perform configuration and compliance checks across all environments. A structured secure configuration review, combined with policy checks, closes many gaps before attackers find them.
- Feed every finding back into engineering and policy updates. Use each OWASP testing report or cyber security audit as a feedback loop, not a one-off hurdle.
Cloud, containers and APIs are now one connected story. Treat their security the same way.
Keep controls simple, consistent and as automated as you can. Focus on visibility, tested baselines, and regular validation through secure configuration review, OWASP testing, and cyber security audit activities.
