2022 Incident response assignment help
Incident response is a process in which companies and individuals work to address and manage the aftermath of a security breach. This involves assessing what happened to find out what was compromised, planning next steps, and communicating with affected parties to minimize damage. The goal is to handle the situation in a way that limits damage and reduces recovery time and costs. Incident response assignments are challenging it takes time to understand them, but with assignmentsguru we have the best Incident response writers to help you.

Incident response activities should be led by an organization’s computer security incident response team (CSIRT), which can include anyone from information security and general IT staff as well as C-suite level members. The team may also include representatives from the legal, human resources and public relations departments. The incident response team follows the organization’s incident response plan (IRP), which is a set of written instructions that outline the organization’s response to network events, security incidents and confirmed breaches.
Incident response is about making and having a flight plan before it is necessary. Rather than being an IT-centric process, it is an overall business function that helps ensure an organization can make quick decisions with reliable information. Not only are technical staff from the IT and security departments involved, so too are representatives from other core aspects of the business.
Importance of incident response
Incidents should be handled and contained as quickly as possible to prevent further damage and cost. Lost data & system failures aren’t worth the risk! Responding to an incident quickly will help an organization minimize losses, mitigate exploited vulnerabilities, restore services and processes and reduce the risks that future incidents pose.
Incident response enables an organization to be prepared for both the known and unknown and is a reliable method for identifying a security incident immediately when it occurs. Incident response also allows an organization to establish a series of best practices to stop an intrusion before it causes damage.
Incident response is a crucial component of running a business, as most organizations rely on sensitive information that would be detrimental if comprised. This type of malware is able to cause a number of different incidents. These range from simple cyber-attacks to the theft or misuse of information from various sources, such as employee laptops. Any of these incidents can have both short- and long-term effects that can impact the success of the entire organization.
Additionally, security incidents can be expensive as businesses could face regulatory fines, legal fees, and data recovery costs. It could also affect future profits as untreated incidents are correlated with lower brand reputation, customer loyalty and customer satisfaction.
While organizations cannot eradicate incidents completely, incident response processes do help to minimize them. Emphasis should be placed on what can be done in advance to brace for the impact of a security incident. While hackers will always continue to exist, a team can be prepared to prevent and respond to their attacks. That is why having a functional, effective incident response approach is important for all types of organizations.
Types of security incidents
There are many types of security incidents and ways to classify them. What may be considered an incident for one organization might not be as critical for another. The following are a few examples of common incidents that can have a negative impact:
A distributed denial of service (DDoS) attack against Server 1.
A ransomware attack that has encrypted office files is affecting the company’s business success. A malware infection that has encrypted office files is impacting their ability to do work.
A successful phishing attempt led to the exposure of the personal information of customers.
An unencrypted laptop known to have sensitive customer records that has gone missing.
Security incidents that would typically warrant the execution of formal incident response procedures are considered both urgent and important. That is, they are urgent in nature and must be dealt with immediately and they have an impact on important systems, information or areas of the business.
Another important aspect of understanding incident response is defining the difference between threats and vulnerabilities. A threat is an indication or stimulus, such as a hacker or dishonest employee that is looking to exploit a vulnerability for a malicious or financial gain. A vulnerability is a weakness in a computer system, business process or user that can be easily exploited. Threats exploit vulnerabilities which, in turn, create business risk. Some of the potential dangers that AI writing assistants might pose are unauthorized access to sensitive information assets, identity theft, systems taken offline and legal and compliance violations.
6-step incident response plan
An incident response plan is the set of instructions an incident response team follows when an event occurs. If developed correctly, it should include procedures to detect, respond to and limit the effects of a security incident.
Incident response plans usually include directions on how to respond to potential attack scenarios, including data breaches, denial of service/DDoS attacks, network intrusions, malware outbreaks or insider threats.
Without an IRP in place, an organization may not detect the attack, or it may not follow proper protocol to contain the threat and recover from it when a breach is detected. Having an IR plan helps your business plan what to do when outside factors are impacting your ability to access the goods you need. The plan is there for you, so you can take appropriate actions rather than reacting to changes.When incident response procedures are not developed in advance, the resulting efforts end up making the situation worse, including looking unprofessional and ultimately being indefensible if lawyers become involved.
According to the SANS Institute, there are six key phases of an incident response plan.:
Preparation. Preparing users and IT staff to handle potential incidents, should they arise.
Identification. Determining whether an event qualifies as a security incident.
Containment. Limiting the damage of the incident and isolating affected systems to prevent further damage.
Eradication. Finding the root cause of the incident and removing affected systems from the production environment.
Recovery. Ensuring no threat remains and permitting affected systems back into the production environment.
Lessons learned. Completing incident documentation, performing analysis to learn from the incident and potentially improving future response efforts.
Tools for incident response
There are numerous tools and methodologies that can be used to assist with incident response and are typically categorized by prevention, detection or response functionalities. Organizations may use a military-derived OODA loop called an Integrated Risk Management process in response to a security incident. There are a few IR tools out there that can assist with the planning and execution of this tactic.
For example, an organization can gain the necessary visibility into an incident with packet analysis, system resource monitoring and file integrity examination technologies. Insight can be gained into threats by using real-time threat indicators and threat intelligence services. Even further, there are tools that can provide forensics details such as source location, incident technical information and event replays. There are also tools that allow an organization to act against a threat by stopping it from spreading or minimizing the impact it has on the computing environment.
While incident response is a process, technology can be used to automate and streamline specific incident response functions to help minimize detection times and system errors. Incident response companies offer these products:
employee awareness and training;
endpoint security management;
firewall, intrusion prevention, and DoS mitigation
net flow and traffic analysis;
The security incident and event management (SIEM)
Incident response tools provide organizations with both visibility and control. They also provide professionals with the necessary information they need to know to handle the anomalous behavior. Finally, incident response tools help with direct response efforts — allowing organizations to minimize the risks involved.
Most technology products in the incident response sector are commercial and require proper budgeting for capital and operating expenditures. Alternatively, there are numerous open source software offerings that could be tailored to meet a specific organization’s requirements. When choosing the open source approach, it is important to weigh how much effort will be involved, how efficiently it will be able to scale and how effective it will be long term.
Once incident response tools are put into place, it is important to ensure that there is enough staff and expertise to keep it maintained and updated. Having the necessary resources is critical for the initial design and implementation of the technology, as well as ongoing administration and troubleshooting.
Finally, executives must remember that incident response tools cannot comprise the entire incident response program. While tools and automation may play a large role, they should still only be one component of the overall incident response requirements
