Cyber security threats have become more numerous and more disruptive. New types of security incidents arise frequently. Preventive actions on the basis of the outcome of risk assessments can diminish the number of incidents. Consequently, an incident response capability is essential for promptly and proactively hunting down incidents, mitigating the shortcomings that were exploited. We at Swiss Cyber Forum understand that improving incident response capability demands substantial planning. So, we’ve made a presentation where we revealed how to develop a triumphant cyber security incident response.

What is a security incident?
First things first, let’s define security incident. A cyber security incident is event (like unauthorized system access) that menaces the confidentiality, integrity or availability of the information resources as well as digital assets that belong to an organisation, such as Customer email addresses, payment information, business financial records, and bank account details. after all, this data has some value to someone. As regards incident response, it’s the actions taken to secure and restore the normal operational conditions of an information system, when a cybersecurity incident takes place. The essential objective of an incident response is to efficiently handle the incident, and eventually keep the damage at a minimum.
How to respond to a cyber security incident?
Organisations vary substantially with respect to the level of maturity in their cyber security incident response capacity, but also in the way in which they need to respond. Yet, good practices exist. Before going any further, we must note that cyber security incident shouldn’t be seen as if it is a single one-off event. Following are the 4 steps to respond to a cyber security incident.
1. Identify the incident
Interestingly, for most organisations, the most difficult part of the incident response process is precisely identifying and evaluating likely cyber security incidents. Identifying the incident normally begins by inspecting evidence of extraordinary happenings and assessing trigger points. Another real challenge is that some incident can be easily spotted, whereas others are almost unfeasible to discern.
2. Determine objectives and examine situation
As soon as a cyber security incident has been identified, the objectives for the response activities should be determined. In that stage, there are numerous questions that need to be answered:
- Who attacked the organisation?
- What is the scope of the attack?
- When exactly did the attack take place?
- What information has been stolen?
- What networks or assets have been corrupted?
- What potential impact does the attack have?
3. Take necessary action
The third step is highly critical, that after the initial investigation the damage must be contained, for instance by stopping it from spreading to other networks within the or beyond. This process can also be called containment, which typically includes several concurrent activities aimed at minimizing the immediate influence of the cyber security incident, principally by eliminating the attacker’s access to organisation’s assets. The main objective here is to make the greatest efforts to return to functionality as normal.
4. Recover systems and information
The last step is to restore systems to normal operation, and to verify that the systems are operating normally again. This can often be accomplished by performing an independent penetration testing of the comprised systems. It goes without saying that sophisticated cyber criminals will try to infiltrate the network again through all of the methods at their disposal. for that reason, it’s crucial to make sure that all elements of the attack have been exterminated, so that the intruders cannot carry out further attacks.

Swiss Cyber Forum brings together individuals and organisations through organising workshops, webinars, educational training, and global conferences and provide a digital platform for the wider community at the global level. We’ve developed a Cyber Security Specialist training with Swiss Federal Diploma that incorporates practice-oriented case studies and cyber incident challenges.
Cyber security jobs are in high demand, so we’ve recently shared 3 cyber security career advice no one tells you, which’ll help you remain competitive. We’re also very excited to have published our first whitepaper on how data breaches can be prevented.
