Nowadays, data dump, extortion software attacks and malware attacks are common, which means that event management strategy has become a necessary option. It's not a question of whether the event will happen, but when. Moreover, due to the hyperconnection characteristics of the current IT environment, the workload based on cloud computing is particularly vulnerable to attack. (source: enterprise network d1net)

Without a defined response process, businesses will not be able to respond appropriately to security threats or unexpected infrastructure or application issues. Fortunately, event management is a perfect process.

To reduce the pressure on planning, there are five steps you need to understand to identify, remedy, and adapt before an event occurs.

Step 1 : preparation

One of the most important things for an enterprise IT team to establish a cloud computing event response process is to prepare for the inevitable events. Although preparation can take different forms, it is usually divided into three categories: training, documentation, and aggregation.

(1) Training
In terms of cloud computing event response, deploying the right people is only half of the process. Enterprises also need to train their employees and provide sufficient information and support to deal with the incident when it occurs.
Cloud native organizations must ensure that their employees understand how to select their provider's interface to gather information and respond to what is discovered. It also means that employees should understand the enterprise's event management plan and expectations for them.

(2) Documentation
Enterprises should have reliable documents to operate effectively. In order to support employees who may respond to accidents, this means that accurate operating manuals need to be created and maintained. Runbook is a series of routine operations and processes that employees can execute when they respond to predictable events in the production environment.
Runbooks are not limited to security events, because they can also guide employees through tasks such as how to expand the database or restart stuck processes. In event management, runbook is the first line of defense for employees who are not familiar with the enterprise architecture.

(3) Polymerization
Data is key when it comes to the ability of the event response team to identify what happened, how it happened, and why. Although log aggregation and analysis can be very expensive, this information is the basis for any identification, classification, and repair work that will be done in subsequent steps.

Step 2 : confirm

efore the team can respond to an event, they need to determine when it happened. This can be achieved in a variety of ways, but it is often necessary to identify abnormal behavior. This is a manual process, which is processed by combing user reports or viewing logs and analyzing data, but the implementation of automated tools is the only scalable way to identify abnormal behavior in large cloud computing environments.
After identifying events through manual or automated processes, many organizations may choose to notify their cloud computing providers and cross validate them. This step ensures that the enterprise responds to actual events, and in case of time constraints, the support of cloud computing providers can help to quickly end the cycle.

Step 3 : coordinate

Once the event is identified, the next step is to organize. Before you actually solve all problems, you need to understand the nature and severity of the problem and define and work with the response team. In this step, the person on duty or the enterprise employee will be responsible for determining the nature of the report and making an initial assessment of the severity before passing it on to their team members.
Build response team:
Many cloud native organizations may be small, but each event can be handled by their team members. However, the larger the organization, the more important it is to be able to find technical experts who have problems.
After the event occurs, it is transferred to team members (also known as event directors), who will identify cross functional leaders from relevant teams to create a cloud computing event response team. The team will be responsible for investigating and correcting problems.

Step 4 : Remedy

Once the activity event has been identified and a response team established, investigate and resolve the problem. Other team members and resources may be required to gather as much information as possible when the response team conducts the survey.
Due to the inherent unpredictability of events, it is difficult to set a schedule in this process. Keep internal communication channels open to track progress and understand the overall impact.
In terms of network security, it is most likely to lose customers' trust if they do not inform customers of the problems that may affect them. It is important to have a clear understanding of the situation at the time of the accident and how to remedy it. The method of not reporting events to customers and then exposing them later needs to be used with caution. When in doubt, mistakes can be made in terms of transparency.

Step 5 : Review

Review is the cornerstone of the event response process of agile cloud computing. It enables enterprises to learn from past mistakes and take corrective measures to ensure that the measures are constantly improving. Highlight where things are going well and identify areas for improvement to help define action items. This enables the enterprise's response team to learn from past events and prepare for the next.
