How to Craft a Prevention and Response Plan for a Network Incident

Reading Time: 3 minutes


Nowadays, organizations preserve their data in cloud storage to keep the workflow in control without worrying about the hassle of paperwork. But the more organizations use data storage, the more they are at risk of a network incident.

A network incident is where the data of an organization is at risk of being compromised. Hackers try to break into the security system of the organization to get into their data. They can use this data to either get direct money from the business or to destroy an organization. In either case, it can ruin a company’s reputation and those associated with it.

Hackers are becoming more and more skilled every day, bringing about the need for an incident security handler. The industry is growing at a rapid speed with very few skilled people available. This article will talk about what a cyber incident is, the types of security incidents, and what every incident handler should know when dealing with a network incident.

What Is a Cyber Incident? How Does It Occur?

A cyber incident can take place in any manner. It can harm your system, causing it to shut down repeatedly, or it can attack your data file, directly making it visible to everyone. Initially, some of the incidents seem small, but even these incidents can bring a lot of damage to an organization.

Example: When the system shuts down, again and again, employees will not be able to work till the incident is resolved. The company will face a loss in gross profit. That one-day incident can cost employees one month’s overtime at the bare minimum.

When such a case occurs, an incident security handler helps organizations resolve the incident with minimum donwtime and loss.

Types of Security Incidents

There are various types of security incidents, but the most commons ones are:

DDoS attacks

Also known as a distributed denial of service attack, this type of attack overwhelms the system making it unable to process a request. In this incident, the attack is launched by host machines that are infected with malicious software.

Drive-by attack

When hackers see a less secured website, they infect the HTTP or PHP with malicious script. Whenever someone clicks on the website, it can either allow the hacker to access the victim’s computer directly or download malicious scripts on their computer.

What Incident Responders Must Know About Networking

While handling incident security, the incident handler should know about the assets at risk, both physical and data. When you are constantly working to resolve a incident, there is always a risk of spreading it further.

An incident responder should know the difference between normal, acceptable traffic and unacceptable traffic of a network. For this, handlers should have a good knowledge of the device that is being used. To understand the breach handler should also understand the different network traffic for different devices.

Cyber Incident Response Steps to Take While Handling an Incident

Cyber incident response should be planned beforehand to ensure the safety of unaffected network areas. The possible outcomes of an incident response plan should also be considered.

  • Identify: An incident can be identified by a monitoring system for irregular behavior. It means first you need to figure out what type of incident it is if it’s data theft, network attack, or a series of threads.
  • Containment Areas: After the incident has been identified, the entire network needs to be checked to look for containment areas. This step is very important for the organization because if any area remains unidentified, it can be breached again.
  • Response: Once all the areas are marked, the handler can finally work with the response plan. Handler needs to eliminate all causes causing systems and networks to showcase irregular behavior. They also need to ensure that any network incidents do not occur again for a long time.
  • Data Recovery: This is another important step of the response plan. All the lost or harmed data should be brought back in good condition by the handler. The handler should also test all systems to ensure their good working condition.
  • Documentation: All the steps of the response plan should be documented. These documented incidents will come in handy when the organization faces similar incidents in the upcoming future.
