How to handle Cyber Security Incident?
In the event of a cyber security issue, an organization must be able to respond appropriately and quickly. For this reason, it’s critical to plan your response to specific scenarios in advance rather than reacting to them as they arise during an incident. Plan (not just mentally, but on paper) how to minimize damage, cut expenses and recovery time, and coordinate with internal and external stakeholders.
An incident response plan for cyberattacks is dynamic. It is crucial to include it into your company’s operations and to periodically evaluate and update it—annually and as part of the post-incident review, for example.
You can create several standard operating procedures for typical issues that are likely to happen in your company by building on your cyber security incident response strategy. Such a process ought to outline the steps involved in resolving a particular problem. These rapid response manuals for common situations must be freely available.
1. Identifying your Threats and Potential Threats
First things to think about after an incident: whose assets are at risk and which of those assets are essential to your business operations? It will be up to you to prioritize which assets require maintenance to continue operating and minimize any harm to your company.
The resources your organization needs to carry out its fundamental operations are its “vitals,” which should be recognized, recorded, and categorized.
This will enable you to make prompt, well-informed decisions during the event management process and to determine which protective measures to apply were.
2. How to identify, document and categorize your organization’s vitals, vulnerabilities and potential threats
Determine which services in your business and which resources require protection.
- Ascertain which of your main business operations—producing, selling, delivering, etc.—allows your company to continue operating, accomplish its goals, and make money.
- Determine which ICT systems (databases, apps, control systems) and network connections are used to support each of those operations.
- Find out if these ICT systems are housed in the cloud or on your own servers.
- Don’t overlook information flows to other parties (suppliers, clients, etc.) or flows within industrial control systems when identifying these assets.
Identify your crown jewels
Determine now which assets, data, processes, or network connections are so important for your organization that if you lose (control of) them, you are in big trouble or even out of business.
Set recovery-related business priorities.
The process of prioritizing will dictate the sequence in which the systems are restored. Since the underlying network is both how cybercriminals target your systems and how your system administrators may access your assets, it is usually necessary to give it the highest priority. Whatever additional recovery effort you conduct could be undone by thieves if they have access to your network connections. When assets are prioritized just as highly, recovery efforts in parallel may be explored.
Maintain current documentation on the operation of your systems.
Make sure that your systems’ operation is recorded, that the documentation for this information is current, and that it is accessible on the incident response team’s documentation system. Make use of ISO 27001 certification implementation that would help you with documentation and control of information security.
3. Responsibility Assigning and forming team that leads Cybersecurity.
Your cyber security incident response plan should include a detailed description of roles and duties in the event of a cyber security incident and cyber security information. You will come to understand that diverse skills are required to assume the various roles and duties required in an effective incident response in order to appropriately resolve a cyber security issue.
Cyber Security Response Team
Every organization should, in theory, have an incident response team that is called upon in the event of an occurrence. The size and composition of the incident response team are, of course, determined by the size of the organization. Smaller businesses without the resources for a full team should appoint a first responder from within their staff, ideally someone with the ability to make business decisions. He or she should seek outside assistance in the event of a cyber security problem, but they will still be ultimately in charge of the organization’s incident response.
4. External Cybersecurity Experts
Gaining and retaining all the in-house knowledge and abilities required for crisis response is expensive, regardless of the size of your company. This is particularly true for cyber security incident response skills that involve forensics and legal advice. Therefore, keep in mind that, in order to bridge the skills gap in your organization, it might be more economical to engage outside partners for cyber security incident response.

5. Prepare Communication Strategy
Every stage of responding to a cyber security event requires communication. To make sure the right information is sent to the right receivers at the right time by the right senders, you want to oversee the communication flow. This holds true for both communications with the outside world and communications within. We advise working with the public relations and legal representatives to coordinate all communications with the outside world.
The kind of communication needed will depend on the incident’s nature and possible effects. For instance, it is quite unlikely that an internal fraud case or an inside hacking effort will justify informing the media about the incident.
IDENTIFY INTERNAL AND EXTERNAL STAKEHOLDERS
Information from a wide range of stakeholders will be continuously needed during the incident response efforts. They will all require distinct kinds of information. Create a list of possible stakeholders and make sure the appropriate contact details are listed! It should be noted that while communication with all parties is not always necessary, the organization should have this contact information on hand.
