Cyber Incident Analysis
The growth of technology has resulted in an increase in the number of cybersecurity events as well as their sophistication. A computer system is being attempted to be infiltrated or rather hacked somewhere in the world practically every second of every day of the year. A cybersecurity incident can be described as an intentional act to interfere with or disrupt the physical or electronic security perimeter of a key cyber asset that has been identified. Social events, misuse incidents, hacking incidents, and virus attacks are all types of cybersecurity occurrences that can be classified. Cyber-attacks can be directed at a variety of targets, including domain name systems, network infrastructure, websites, and even apps. Individuals, businesses, and organizations are seeking ways to be better protected from cyber-attacks as a result of an increase in the number of incidents where cyber security has been breached. There are several steps involved in cyber incident response, which include detection, recognition, analysis, appraisal, restraint, and obliteration as well as recovery from the incident and lastly post-incident recovery. The majority of this essay will be devoted to the investigation of cyber events.
What Cyber Incident Analysis Is and What It Does
When we talk about cyber incident analysis, we are referring to the meticulously planned process of determining what took place, why and how it occurred, and what can be done to prevent it from occurring again. A cyber incident analysis report can be used to assess the purpose of a cyber-attack as well as the degree of the harm that has been caused by the attack. It is a critical phase in the response to a cyber incident, as it prepares the path for the other measures that will follow. This means that if the response plan does not include an analysis component, it is considered a failure. This loop can be used to describe the incident analysis process as well as the tools that are employed in the process. The OODA loop is comprised of four simple steps: observation, orientation, decision, and execution.
Observe
In this case, an individual or organization is responsible for identifying any odd conduct that may necessitate further investigation. It is possible to utilize several different tools, such as log management tools, intrusion detection systems, network traffic analyzers, vulnerability scanners, intrusion detection systems, and web proxies. The goal of log management is to know about what is happening in your network. This includes the individuals who come to see it. When a server experiences abnormal activity, intrusion detection systems (IDS) use attack signatures to identify it and send out a warning to the appropriate personnel. To trace the traffic in your network, net-flow analyzers must first evaluate a specific thread of activity. Finally, vulnerability scanners identify areas of weakness that may have predisposed a business to be targeted by an attacker.
It is Orient’s responsibility to assess what is happening in your cyber threat landscape to create coherent links and prioritize occurrences. Threat intelligence, security inquiry, and asset inventory are some of the techniques that are used for orienting. Asset inventory enables you to acquire a comprehensive understanding of all of the essential systems in your network, as well as the exact software that has been put on them. To determine the severity of a cyber attack, you would need to have a thorough grasp of your immediate environment, which is provided by the inventory. Threat intelligence brings you up to date on potential cyber dangers that are occurring in the physical world. They include items such as compromise indicators and IP addresses with a negative reputation, and they can be used to present a complete picture of the threat.
Decide focuses on the application of your observations and context to develop a reaction that will do the least amount of damage while allowing for the quickest recovery. In this case, only two tools are used, namely the company’s corporate policy and its supporting paperwork. Both of these tools are intended to provide information on what is acceptable and what is not. They are not interchangeable. The threat should be classified and then a reaction should be devised following the company’s policies and other paperwork, according to the instructions given above.
The use of lessons acquired from cyber incidents to commence incident response and recovery are two examples of what is required. In this case, a wide range of tools is used, including backup and recovery software, system management software, security awareness software, and incident response forensics software. Aiming to investigate digital trails, incident response forensic tools are used for the detection, analysis, and display of facts about digital information to respond to incidents. Security tools, on the other hand, are intended to improve the overall security of a system to lessen the risk of a similar incident occurring again.
It is vital to remember that cybersecurity is never a problem that arises after an attack has occurred, but rather begins even before an assault is carried out. As a result, organizations should collaborate with their information technology staff around the clock to ensure that their security processes are up to date and technologically relevant.
