Cyber Incident Response for Australian Businesses
A cyber incident without an incident response plan is a crisis. With one, it is a managed event. PIP’s cyber incident response service covers both sides — helping businesses build and test an incident response plan, and providing hands-on response when a cyber incident occurs.
What is cyber incident response?
Cyber incident response is the structured process of detecting, containing, eradicating and recovering from a cyber security incident — and then conducting a post incident review to identify lessons learned and prevent recurrence. An effective incident response plan is a documented response playbook developed before a cyber incident occurs — defining roles, escalation paths, communication plan, containment steps and regulatory notification obligations for each incident type.
Businesses without a response plan make reactive, uncoordinated decisions during a cybersecurity incident — slowing containment, increasing further damage and risking regulatory non-compliance. Effective incident response reduces both the direct cost of an incident (downtime, data loss, recovery expense) and the indirect cost (regulatory penalty, reputational damage). The preparation phase is where most of the value sits — when the incident occurs, it is too late to write the response plan.
PIP provides cyber response capability at two levels: response plan development and testing (the preparation phase, before an incident), and hands-on cybersecurity incident response and cybersecurity incident response and cybersecurity incident response engagement (during and after a security incident). PIP’s incident response team includes security analysts and security team members who already know your environment — because PIP manages it. This capability means faster containment, better forensic evidence preservation and more effective response overall.
What counts as a cyber incident?
A cyber security incident is an event that has compromised — or has the potential to compromise — the confidentiality, integrity or availability of information or IT systems
For Australian businesses, a cybersecurity incident may include:
- A ransomware attack — files encrypted, critical systems locked
- A data breach — personal or sensitive data accessed without authorisation
- An account compromise — email or business application accessed by a threat actor
- A phishing attack resulting in credential theft or financial loss
- A business email compromise (BEC) resulting in a misdirected payment
- Malware infection — viruses, spyware, keyloggers on affected systems
- A denial-of-service attack — systems and business operations made unavailable
- An insider threat — intentional or negligent misuse by staff
Not every IT problem is a cyber incident — but the incident response plan should define the threshold clearly so that security teams take the right actions when a real cyber incident occurs, rather than treating it as a routine IT issue. Security incidents require a different escalation path. Identifying incidents early is the difference between containment and crisis. The incident response procedures and response plan must distinguish between real threats, false positives and routine security information and event management alerts.
Types of cyber incidents PIP responds to
PIP’s incident response team has experience with the specific cyber incident types that affect Australian businesses. Each requires a different response process — here is how PIP’s cyber incident response handles each one.
Ransomware
PIP’s ransomware incident response focuses on immediate isolation, recovery from tested backup, forensic investigation to identify the entry point and — where a payment is made — mandatory reporting to the Australian Signals Directorate under the Cyber Security Act 2024. Ransomware is one of the most common cyber attacks requiring incident response.
Data Breach
A data breach involves unauthorised access to personal or sensitive data. PIP assists with breach assessment, containment, NDB scheme notification where the breach meets the threshold, and security controls review to prevent future attacks. Data breaches, security breaches and data breaches involving personal information are the incident types most likely to trigger regulatory obligations and public relations considerations.
Business Email Compromise
BEC attacks exploit trusted business communications to redirect financial transfers. PIP’s BEC incident response covers account containment, forensic review of email access logs, communication with affected parties and Essential Eight security configuration changes to prevent recurrence.
Account Compromise
When a business account is compromised, the threat actor has access to communications, files and potentially connected systems. PIP’s response covers account containment, access log review, credential resets, MFA enforcement and risk assessment of what security data and sensitive data may have been accessed by authorized users versus the attacker.
Malware Infection
Malware infections — including keyloggers, spyware and remote access trojans — can persist undetected for extended periods. PIP’s response covers isolation of compromised endpoints, forensic investigation to determine dwell time and malware type, complete eradication, patching vulnerabilities, and security posture review using endpoint detection and security tools.
Insider Threats
Insider threats — whether malicious (deliberate data theft or sabotage) or negligent (accidental data exposure by internal teams) — require a different approach than external cyber attacks. PIP assists with forensic investigation, forensic evidence preservation and coordination with legal counsel and human resources as appropriate.
PIP’s six-step incident response process
PIP’s cyber incident response follows a proven six-step lifecycle — steps that ensure every cybersecurity incident is managed systematically. The incident response process is documented in your incident response plan and tested before any cyber incident occurs.
Preparation
The preparation phase is where response planning starts. PIP develops a cyber incident response plan and response playbook documenting roles, escalation paths, communication plan, containment steps and regulatory timelines. The response plan is reviewed annually. Employee training ensures security teams, the chief information security officer and key stakeholders know their roles when a cyber incident occurs. ISO 27001 requires an incident response plan for certification.
Detection and Analysis
Detecting a cybersecurity incident requires threat detection, endpoint detection tools, log analysis, security tools and network monitoring. PIP’s security operations and managed monitoring identify incidents early. Security analysts assess whether an alert represents a genuine cyber incident, classify the incident type, analyze data and determine initial scope — separating genuine cyber threats from noise.
Containment
Containment limits further damage — isolating compromised endpoints, blocking threat actor access and preventing the cyber incident from spreading. Short-term containment isolates the affected systems immediately. Long-term containment strengthens security controls around systems not yet affected. The incident response plan defines containment procedures for each cyber incident type.
Eradication
Eradication involves complete removal of the threat from affected systems — malware removal, credential resets, configuration hardening, patching vulnerabilities and closing the access path the threat actor or threat actors used. Failure to fully eradicate the threat from critical systems results in recurring security incidents, other security incidents and future attacks. Security incidents that recur indicate incomplete eradication. The response team validates eradication before recovery begins.
Recovery
Recovery restores affected systems to normal operations — restoring systems from clean backups where ransomware or data corruption is involved, or rebuilding configurations where systems are compromised. PIP validates system integrity before restoring systems and business operations to production, monitoring for residual access. Business continuity planning determines the priority order for restoring critical systems.
Post-Incident Review
After the cyber incident is resolved, PIP conducts a structured post incident review: documenting what happened, the entry point, dwell time, impact and what changes to security controls or response procedures will prevent recurrence. Lessons learned from the post incident review are incorporated into the updated response plan. Lessons learned from the post incident review are the mechanism that turns each security incident into improved capabilities and a stronger security posture against potential threats and cyber threats.
NDB scheme — notification obligations
When a cyber incident involves unauthorised access to personal information
Australian businesses must assess whether the breach meets the NDB scheme notification threshold — and if so, notify both the OAIC and affected individuals. The incident response plan must include these response procedures.
When notification is required
- The security breach involves personal information held by an entity covered by the Privacy Act 1988
- There is likely to result in serious harm to affected individuals
- The entity has not been able to prevent the likely risk of harm through remedial action
Timeline
The OAIC expects notification as soon as practicable — within 72 hours where possible. Delay in notification can result in regulatory investigation and increased penalties. A documented response plan with NDB response procedures reduces notification time and supports your efforts.
What PIP does
PIP assists clients in breach assessment (determining whether the cyber incident meets the notification threshold), drafting the OAIC notification and preparing the communication to affected individuals and internal stakeholders. The NIST Cybersecurity Framework and National Institute guidance on incident response align with these steps, though Australian obligations follow the Privacy Act.
“The businesses that handle incidents well are the ones who’ve thought about it beforehand — not in a theatrical way, but in a practical way. They know who calls who. They know which systems to isolate first. They know whether their backups are actually restorable. They’ve had the conversation about whether to pay a ransom before they’re sitting at a blank screen at 6am deciding. The ones who handle it badly are the ones who haven’t had any of those conversations — and every decision gets made under pressure with incomplete information.”

Initial triage call
PIP’s incident response team assesses the situation, identifies the cyber incident type and scope, and provides immediate containment guidance. The response team uses security tools to begin remote assessment.
Remote access or on-site engagement
Depending on the nature and severity of the cybersecurity incident, PIP engineers remote in or attend on-site in Sydney and Greater NSW. Security operations begin immediately from PIP’s security solutions infrastructure.
Containment actions
PIP isolates compromised endpoints, revokes threat actor access and stops the incident from causing further damage. Containment preserves evidence for the investigation phase.
Forensic investigation
PIP investigates the entry point, dwell time, lateral movement and data accessed — producing a forensic timeline that documents the full scope of the incident. This investigation uses security tools and security orchestration for log correlation and analysis.
Recovery
PIP restores systems from clean backups or rebuilds affected systems, validating integrity before restoring systems to normal operations. Business continuity priorities determine the restoration sequence for critical systems.
NDB assessment and notification
PIP assesses whether the incident meets the NDB notification threshold and manages the notification process with the OAIC where required. Risk assessment documentation is prepared for the organisation’s records.
Post-incident report
PIP produces a written incident report with lessons learned — suitable for board, insurer, public relations or regulator discussion. The report feeds into the updated response plan, strengthening capabilities for the future.
Does your business have an incident response plan?
An incident response plan costs a fraction of a cyber incident without one. PIP builds, tests and maintains your incident response plan — so when the cyber incident happens, your response team knows exactly what to do.

A cyber incident response is the structured response process of detecting, containing, eradicating and recovering from a cyber security incident. It includes both planning (developing an effective incident response plan before a cyber incident occurs) and action (executing the cyber incident response plan when a security incident happens).
Effective response limits the damage caused by a cyber incident, reduces downtime to systems and business operations, and helps businesses meet their regulatory notification obligations under the NDB scheme and Cyber Security Act 2024. An effective response plan is the foundation of all response capabilities.
PIP’s cyber incident response follows a proven six-step incident response lifecycle: Preparation (developing the incident response plan and employee training for security teams during the preparation phase), Detection and Analysis (identifying and classifying the cybersecurity incident using security tools and threat detection), Containment (isolating compromised systems and stopping the spread), Eradication (completely removing the threat and patching vulnerabilities), Recovery (restoring systems from clean backups and validating integrity) and Post-Incident Review (documenting lessons learned and updating the incident response plan).
Each step in the incident response process has defined actions and time expectations — which is why having a cyber incident response plan in place before an incident occurs is critical to effective response.
If a cyber incident results in a data breach involving personal information and is likely to cause serious harm to affected individuals, your business is required to notify the OAIC and affected individuals under the Privacy Act 1988 NDB scheme. The Cyber Security Act 2024 also requires businesses to report ransomware payments to the Australian Signals Directorate within 72 hours of payment. Data privacy regulations require documented response procedures for all reportable incidents.
PIP assists clients in assessing whether notification is required and managing the notification process. The response plan should include these notification procedures so the response team can act within the required timelines during a security incident.
The immediate priority is containment — isolate compromised systems from the network to stop the incident from spreading and causing further damage. Do not restart or attempt to repair compromised machines (this can destroy forensic evidence). Do not pay a ransom without first understanding your recovery options and legal obligations from legal counsel.
Contact PIP immediately — PIP’s incident response team will assess the cybersecurity incident, provide containment guidance and initiate the cyber incident response process. The earlier PIP is engaged, the more response capabilities are available and the lower the overall impact on your business operations from cyber threats. Having a tested response plan and knowing who the intended recipient of the initial call is can save hours during the critical first response.
