What are Information Security Incidents in ISO 27001?

Information security incidents are any events that may hurt the confidentiality, integrity, or availability of information. In ISO 27001, information security incidents are defined as "Security events that have potentially adverse consequences."

There are four main types of information security incidents:

  1. Confidentiality breaches
  2.  Integrity breaches
  3. Availability breaches
  4. Insider threats

We'll take a closer look at each of these four types of information security incidents.

1. Confidentiality Breaches

A confidentiality breach is any unauthorised disclosure of information. This can include data leaks, hacking, and espionage. Confidentiality breaches can have serious consequences, such as financial loss, reputation damage, and loss of competitive advantage.

2. Integrity Breaches

An integrity breach is any unauthorised modification of information. This can include data corruption, tampering, and theft. Integrity breaches can have serious consequences, such as financial loss, reputation damage, and loss of customer trust.

3. Availability Breaches

An availability breach is any event that prevents authorised users from accessing information. This can include denial of service attacks, ransomware attacks, and system outages. Availability breaches can have serious consequences, such as lost productivity, missed deadlines, and reputation damage.

4. Insider Threats

Insider threats are a type of security incident that occurs when an individual with authorised access to an organisation's systems uses that access to commit fraud or steal data. Insider threats can have serious consequences, such as financial loss and reputation damage.

Why is Information Security Incident Management Important In ISO 27001?

Information security incident management is an important part of ISO 27001, the international standard for information security management. An incident is defined as a security event that has resulted in or could result in unauthorised access, use, disclosure, interception, or destruction of data. Security incident management is the process of identifying, responding to, and mitigating the effects of incidents.
The purpose of incident management is to minimise the negative impact of incidents on organisational assets, including data, systems, and personnel. Effective incident management requires the ability to identify and respond to incidents quickly and effectively. It also requires the ability to coordinate the response of multiple organisations and individuals.

There are many reasons why information security incident management is important in ISO 27001.

  • First, it can help organisations identify and assess incidents so they can determine the appropriate response.
  • Second, it can help organisations investigate and determine the root cause of an incident. Third, it can help organisations develop and implement corrective and preventive actions to prevent similar incidents from happening in the future.
  • Finally, incident management can help Organisations communicate with stakeholders about incidents and keep them updated on the organisation's response.

How Do You Get Started With Incident Management in ISO 27001?

One of the key requirements of the ISO 27001 standard is the incident management process. This process must be designed to ensure that any security incidents are promptly identified, investigated, and managed in a way that minimises the negative impact on the organisation. We'll look at how to get started with incident management in ISO 27001.

    1. Define the scope of your incident management process - The first step is to identify what incidents will be managed by the process. This will depend on the size and type of organisation, as well as the nature of its business. For example, a small organisation might only need to manage incidents that result in data breaches, while a larger organisation might need to manage a wider range of incidents, such as power outages or network failures.
    2. Identify who is responsible for each stage of incident management - The next step is to identify who will be responsible for each stage of incident management. This will ensure that there is a clear chain of command and that everyone knows their role in the event of an incident.
    3. Create an incident management plan - Once you have identified the scope of your incident management process and who is responsible for each stage, you can start to create an incident management plan. This plan should detail how incidents will be reported, who will investigate them, and how they will be resolved.

What is the Annex A 16 Controls In ISO 27001?

Annex A of ISO 27001 is a list of 16 security controls that organisations can use to improve their information security management system (ISMS). These controls are designed to protect information assets from a variety of threats, including unauthorised access, disclosure, and destruction. Some may be more relevant to your organisation than others. We’ll take a closer look at each of the Annex A 16 controls and explain how they can help improve your information security.

1. Access Control

Access control controls who have access to your organisations information assets. This can be done through physical security measures, such as locked doors and fences, as well as through logical security measures, such as user authentication and authorisation.

2. Assets Classification and Handling

Organisations need to properly classify their assets to know how to protect them. This includes categorising assets by sensitivity (e.g., confidential, internal use only, public) and classifying data by type (e.g., personal data, financial data). Once assets are classified, they can be handled appropriately according to their level of sensitivity.

3. Awareness and Training

Information security awareness and training help employees understand the importance of information security and how to protect company assets. Employees should be made aware of the potential consequences of information security breaches, as well as the policies and procedures that should be followed to prevent them. Training should be ongoing and tailored to the specific needs of your organisation.

4. Business Continuity Management

Business continuity management ensures that critical elements in the business are identified and assessed, including supplier relationships, asset tracking, governance and compliance.

Benefits of Information Security Incident Management ISO 27001?

Information security incident management is a process for handling security incidents. It includes procedures for detecting, responding to, and recovering from incidents. ISO 27001 is an international standard that provides guidelines for developing and implementing an information security incident management system. Here are some benefits of ISO 27001:

  • Helps organisations protect their data and systems from security incidents
  • Helps organisations manage and reduce the risk of security incidents
  • Helps organisations recover from incidents more quickly
  • Provides a framework for developing and implementing an incident management system
  • Helps organisations communicate with stakeholders about incidents - Helps organisations train employees on incident response procedures.
  • Helps prevent further damage: Incident management helps to identify the root cause of an incident and take steps to prevent it from happening again.
