5 Steps To Take After A Cybersecurity Incident

Table of Contents

Cybersecurity incidents can happen to any business, big or small. If you’re unfortunate enough to experience one, formulating in advance the Steps To Take After A Cybersecurity Incident is crucial to minimize the damage and protect your company is essential.

What is a cybersecurity incident?

A cybersecurity incident is an event that impacts an organization’s computer networks or systems and can result in the loss of data, unauthorized access to systems, or sabotage of systems.

Cybersecurity incidents can be caused by various factors, including malicious actors (hackers), accidental errors, faulty software or hardware, and natural disasters. They can also stem from an intentional cyber attack, such as ransomware attacks or data breaches.

Organizations should have a comprehensive plan to prevent and respond to cybersecurity incidents. This includes having policies and procedures for identifying and responding to cybersecurity incidents and training employees on how to recognize and respond to them.

Types of cyber Attacks

Data breach

A data breach is when sensitive, confidential, or otherwise protected data is accessed, stolen, publicly released, or compromised by unauthorized individuals. Data breaches can occur through various means, including hacking, device theft or loss, social engineering, and more.

The effects of a data breach can be wide-ranging and potentially devastating for the victims involved. In addition to the potential for financial fraud and identity theft, affected individuals may experience emotional distress and damage to their relationships. Data breaches are also costly for businesses.


Phishing is a cyberattack where a hacker tries to access your passwords and other sensitive information by posing as a trustworthy entity in an email or other communication.

The attacker may try to get you to click on a link, open an attachment, or enter your information into a form on a website. Be very careful about any emails or communications that ask for your personal information, and always check the source’s legitimacy before giving out any information.


A ransomware cyberattack is when a hacker takes control of your computer and encrypts all your files, then demands a ransom payment to release them.

This type of future attack has become increasingly common as hackers have become more sophisticated. Ransomware can be very difficult to recover from, so it’s essential to take steps to prevent it from happening in the first place.

One way to do this is to ensure that you have up-to-date antivirus software and a firm password policy for your company. Additionally, it’s essential to back up your files regularly so that you can restore them if they are ever encrypted by ransomware.

The importance of an incident response plan

Incident response planning is essential for a cyberattack because it ensures that your business has a set of protocols to follow when a data breach occurs, or a hacking incident occurs. Having a plan in place can minimize the damage caused by the attack and ensure that your company can resume normal operations as quickly as possible.

Some critical components of an effective incident response process include:

  • Identifying who will be responsible for responding to the attack.
  • Establishing lines of communication between key stakeholders during an incident.
  • Creating detailed procedures for investigating and responding to a cyberattack.
  • Developing a system for notifying customers and law enforcement authorities about the attack.
  • Training employees on how to recognize and respond to an attack.

Given the increasing frequency and severity of cyberattacks, businesses need to take steps to protect their financial data and systems from potential threats. Incident response plans can help your company better prepare for and respond to a cyberattack, minimizing damage and ensuring that your operations remain as smooth and efficient as possible.

Have your incident response team ready

If you’re not currently experiencing a cyberattack, your incident responders are not ready.

In all seriousness, it’s easier to be prepared for something if you have a realistic sense of what that preparation looks like. So the first step is to understand your organization’s risk profile and then build your response plan accordingly.

There are some basic steps you can take to help ensure that your team is as prepared as possible.

5 Steps to implement after a cybersecurity incident


To respond effectively to security events, you must have a well-thought-out plan. This will help your team members understand what they need and ensure everything runs smoothly in getting started.

IRP policies, communication guidelines, and threat-hunting exercises are essential for successful incident response steps. IRPs should include the following:

  • Developing standards for reporting incidents so they can be handled appropriately with minimal disruption;
  • Defining what information needs more attention than others during an emergency (elevated above average severity).
  • Establishing who will act as leaders within different departments requires a response from people with a particular skill set.
  • Coordinating between agencies and companies to prepare for various threat scenarios, ensuring that the right people are notified of incident information on time, and performing regular drills in case of an emergency.
  • These routines will ensure that your plan is as comprehensive as possible, including all key players, departments, and information so that you can be better prepared for these situations.

Strong communication guidelines

One of the most critical aspects of influential incident response roles is having strong communication guidelines. This includes establishing standards for how to report incidents, defining what types of information require elevated attention during an emergency, and determining who will take a leadership role within different departments when there is a need for specialized skills.

Additionally, it’s essential to coordinate with other agencies and companies to prepare for various threat scenarios; this involves promptly making sure the right people are notified of incident information and performing regular drills so that everyone understands their roles in case of an emergency.

Overall, a comprehensive incident response plan that includes all these critical components will help ensure your organization is well-prepared to respond effectively to any security threat.

By developing strong communication guidelines, establishing clear leadership roles, and coordinating with other organizations, you can better prepare yourself for any potential incidents and minimize their impact on your business operations.


This step aims to monitor security events to detect, alert and report potential incidents.

This means that during the monitoring stage, we’ll be using firewalls and intrusion prevention systems (IPS) or data loss prevention tools for our computers so they can’t leak any information about what you do online, like steal passwords.

Another thing we use is antivirus, a software that scans for known viruses on your computers. We also use these types of equipment because it helps protect against outside attacks from hackers who want access to networks with lower levels of privileges than those holding them. However, unfortunately, there are still people out there that try to commit these crimes.

Anti-spam software does just what the name says, and another vitally important part of monitoring the network has an incident response plan in place. When problems arise, we would immediately know exactly what to do to keep the network running so our users can get back to work.


To effectively respond to a security incident, it is necessary for individuals who are responding parties (such as system administrators) and those investigating the situation alike to have deep knowledge of how various pieces fit together. The more thorough your understanding of what’s happening with live systems during an attack or investigation process-the better chance you will be able to avoid similar problems in future incidents.

Analysis areas to focus on:

Endpoint analysis

The evidence gathered will help analysts determine what tracks may have been left behind by the threat actor. The collection includes artifacts needed to build a timeline of activities, such as Bit-for-bit copies from forensically clean affected systems and RAM captures for parsing through to identify critical events on a device or network connection during compromise attempts.

Binary analysis

The evidence collected should be analyzed in binary analysis, operation behavioral patterns, and static reverse engineering. Behavioral monitoring is done by executing a program on the hard drive while researching its functionality with an open-source tool like Obj-dump or Address-Sanitizer.

Static Reverse Engineering entails understanding how pieces of code work together by reading their functioning prototypes directly from memory instead looking at them as whole programs. Binary analysis is done through a binary editor.

The results of these analyses should be utilized to search for common patterns that indicate malicious software. If reliable indicators are detected, the program should be flagged as potentially harmful and removed from the hard drive for further review by a security analyst. To ensure that no new malicious software has been installed, the system should be cleaned, and potentially hostile programs should be quarantined.

Enterprise hunting

Once analysts determine the scope of the compromise, they should focus on three primary areas. The first is Enterprise hunting, analyzing existing systems and event log technologies to find any additional compromised accounts or machines that may be connected with an attack surface for your organization’s network infrastructure;

this will generate new leads, which we can use in our investigation efforts later down the line. Secondly, you’ll want documentation about all these findings so everything is answered when it comes time to contain/neutralize threats within its borders (assuming you have defined boundaries in the first place). It can also be used to give shape to the company’s security posture.

And finally, it cannot be stressed enough how important it is to communicate all of this information clearly and concisely (see: Security Report Writing) so everyone involved understands what next steps need to be taken.


It is crucial to have an effective containment and neutralization strategy in place when responding quickly after a compromise. This will help ensure that normal operations can resume as soon with minimal downtime while also protecting other systems from being compromised by malware or other threats within your environment.

The goal during this phase should be to identify all susceptible devices (those infected) before they spread further through network traffic; we call these “threat actors.” A notification must then go out so everyone knows what’s going on-including any intrusion prevention experts who might need extra time for cleanup work if necessary. This is all about containment and stopping the spread of a threat before it becomes an even bigger issue.

While it is essential to containing this infection’s spread as quickly and efficiently as possible, we must also consider other implications arising from our actions when you block access points for malicious domains or IP addresses to reduce their effectiveness at command and control.

You may shut down key communication channels used by victims who rely on these services without realizing what they are doing. It would make more sense if responders took steps aimed directly toward helping those people get back online so that they could work toward eradicating the infection.
