Why your business needs a cyber security Incident Response Plan

An incident response plan is a guide to the procedures your business will follow in the event that a cyber attack occurs within your business.  An Incident Response plan should describe the types of incidents for which it will be used and outline actions that need to be taken to minimise the loss of life, property and data during and after an attack.

An incident response plan (IRP) is a comprehensive strategy that outlines the steps an organization should take in the event of a cybersecurity incident or breach. The primary goal of an IRP is to minimize the damage, reduce recovery time, and mitigate the impact of the incident on the organization’s operations, reputation, and sensitive data.

An effective incident response plan typically consists of several key components:

1. Preparation and Planning: This involves establishing a dedicated incident response team comprising individuals with specific roles and responsibilities. The team should include IT professionals, legal experts, public relations representatives, and relevant stakeholders. The plan outlines their roles and defines communication channels.
2. Identification and Classification: The plan defines criteria for identifying and classifying incidents based on their severity and potential impact. This enables the organization to prioritize responses according to the level of threat.
3. Containment and Eradication: Once an incident is identified, the plan outlines steps to contain and isolate the affected systems to prevent further spread of the attack. It also details the process of eliminating the threat from the organization’s network.
4. Recovery and Restoration: The IRP includes guidelines for restoring affected systems to normal operation. This involves verifying the integrity of data and applications and ensuring that no residual threats remain.
5. Communication: Effective communication is crucial during an incident. The plan outlines how internal and external stakeholders should be informed about the incident, while also addressing legal, regulatory, and public relations considerations.
6. Documentation: Comprehensive documentation of the incident, including its timeline, actions taken, and lessons learned, helps the organization refine its incident response strategy in the future.
7. Testing and Training: Regular testing of the incident response plan through simulations and tabletop exercises ensures that the response team is well-prepared and familiar with their roles. Any gaps or weaknesses in the plan can be identified and addressed during these exercises.

An incident response plan is not a static document; it should be reviewed and updated regularly to reflect changes in technology, threats, and organizational structure. By having a well-defined and practiced IRP in place, organizations can respond effectively to cybersecurity incidents, minimize damage, and safeguard their operations and reputation.

Incident response planning is a collaborative effort that involves multiple individuals and departments within an organization. The responsibility for incident response planning is typically shared among various key roles:

1. Chief Information Security Officer (CISO): The CISO is often at the helm of incident response planning. They oversee the organization’s overall cybersecurity strategy and ensure that incident response plans align with the organization’s risk tolerance and compliance requirements.
2. IT Security Team: The IT security team plays a central role in incident response planning. They are responsible for identifying and mitigating threats, implementing security measures, and coordinating the technical aspects of incident response.
3. Legal and Compliance Teams: These teams ensure that incident response plans adhere to legal and regulatory requirements, especially when it comes to data breach notifications and handling sensitive information.
4. Communication and Public Relations (PR) Teams: In the event of a cybersecurity incident, timely and accurate communication is crucial. PR and communication teams are responsible for crafting messages to stakeholders, customers, and the public, maintaining transparency and managing reputation.
5. IT Operations Team: This team is responsible for implementing technical responses outlined in the incident response plan, such as isolating affected systems, recovering data, and restoring normal operations.
6. Senior Management and Leadership: Senior management’s involvement is vital, as they approve budgets, provide resources, and make strategic decisions that affect incident response planning and execution.
7. Human Resources (HR): HR plays a role in incident response by managing internal communication, assisting with employee training and awareness, and ensuring that personnel policies align with the incident response plan.
8. External Experts: Depending on the incident’s complexity, organizations might involve external experts such as cybersecurity consultants, legal advisors, and forensics specialists to provide guidance and support.
9. Employees: All employees have a role to play in incident response. They must be aware of their responsibilities, including reporting suspicious activities, following established procedures, and participating in training and simulations.
10. Third-Party Vendors and Partners: If the incident involves third-party vendors or partners, their involvement might be necessary for coordination and remediation efforts.

It’s important to note that incident response planning is an ongoing process that requires collaboration, training, and regular testing. Organizations should clearly define roles and responsibilities, conduct tabletop exercises, and update the plan as technologies, threats, and the organization’s structure evolve.

An incident response plan (IRP) is a critical component for any business, regardless of its size or industry, due to the increasing frequency and sophistication of cyber threats. Here’s why having an incident response plan is essential for your business:

1. Minimize Damage: Cybersecurity incidents, such as data breaches or malware infections, can have severe consequences for a business, including financial losses, reputational damage, and legal ramifications. An IRP helps minimize the impact of such incidents by outlining specific actions to contain, mitigate, and recover from the incident promptly.
2. Quick Recovery: Without a well-structured plan, responding to an incident can be chaotic and inefficient. An IRP provides clear steps and procedures for your team to follow, which helps expedite the recovery process and reduce downtime.

An incident response plan (IRP) and a business continuity plan (BCP) are both essential components of an organization’s overall cybersecurity and risk management strategy, but they serve different purposes and address different aspects of handling disruptions. Here’s a breakdown of the key differences between an incident response plan and a business continuity plan:

Incident Response Plan (IRP):

1. Focus: An incident response plan primarily focuses on addressing and mitigating the immediate effects of security incidents and cyberattacks. It outlines the step-by-step process to detect, respond, contain, eradicate, and recover from security incidents.
2. Scope: IRPs are specific to cybersecurity incidents and data breaches. They are designed to manage incidents that threaten the confidentiality, integrity, or availability of data and systems.
3. Objectives: The main objectives of an IRP are to minimize the impact of security incidents, preserve evidence for investigation, and swiftly restore normal operations.
4. Timing: IRPs are enacted once an incident is detected. They are activated to handle the incident in real time and to manage the incident’s immediate aftermath.
5. Key Components: An IRP includes roles and responsibilities of incident response team members, communication protocols, incident categorization, response procedures, and post-incident analysis.

Business Continuity Plan (BCP):

1. Focus: A business continuity plan addresses the organization’s ability to continue operations during and after disruptions. It focuses on maintaining essential functions, services, and operations despite unexpected events.
2. Scope: BCPs cover a broader range of disruptions, including natural disasters, equipment failures, power outages, supply chain disruptions, and other incidents that could interrupt regular business operations.
3. Objectives: The main objectives of a BCP are to ensure the organization’s resilience, minimize downtime, and prioritize critical business functions to enable continuity.
4. Timing: BCPs are proactive in nature and encompass both pre-incident and post-incident phases. They include measures to prevent disruptions, as well as strategies to recover and restore operations after disruptions occur.
5. Key Components: A BCP includes risk assessments, business impact analyses, strategies for maintaining critical functions, recovery procedures, communication plans, and the allocation of resources during and after disruptions.

In summary, an incident response plan focuses on managing and mitigating the immediate effects of cybersecurity incidents, while a business continuity plan addresses the organization’s overall ability to continue operations and recover from various types of disruptions. Both plans are integral to an organization’s overall resilience and should complement each other to ensure comprehensive risk management and operational stability.

In Australia, organizations are subject to various legislations and regulations that mandate the reporting of cybersecurity incidents, particularly those involving data breaches or cyberattacks that compromise personal information. The key legislation that addresses reporting cyber incidents in Australia is the Notifiable Data Breaches (NDB) scheme under the Privacy Act 1988 (Cth).

Notifiable Data Breaches (NDB) Scheme: The NDB scheme, which came into effect on February 22, 2018, amends the Privacy Act 1988 to require organizations to notify affected individuals and the Office of the Australian Information Commissioner (OAIC) of eligible data breaches. An eligible data breach occurs when there is unauthorized access to or disclosure of personal information that could result in serious harm to individuals.

Under the NDB scheme:

1. Notification to Affected Individuals: If an organization becomes aware of a data breach that is likely to result in serious harm to individuals whose personal information is involved, it must notify those individuals as soon as practicable.
2. Notification to OAIC: Organizations are also required to notify the OAIC of eligible data breaches. The OAIC provides guidelines on how to report breaches and the information that should be included in the notification.
3. Penalties: Failure to comply with the NDB scheme can result in significant penalties, including fines. The OAIC has the authority to investigate and take enforcement action in cases of non-compliance.

It’s important to note that the NDB scheme applies to entities that are covered by the Privacy Act, including government agencies and private sector organizations with an annual turnover of AUD 3 million or more, among others.

Apart from the NDB scheme, various sector-specific regulations and guidelines may also apply to specific industries. Organizations are advised to stay informed about the evolving legislative landscape and ensure compliance with relevant regulations to fulfill their obligations for reporting cybersecurity incidents.

The goal of an Incident Response Plan is to help your business avoid, mitigate and respond to a cyber attack in a considered and timely manner.  Developing a cyber security IR plan is an ongoing management exercise, not a one-off event – it should be reviewed and updated regularly to be effective.

Businesses should introduce IR training and exercises including live attack scenarios to strengthen their cyber security posture.  What worked in the past might not work tomorrow.  The right IR plan should be a living document that is up to date and considers the evolving threat landscape.
