How important is it to have enough knowledge in cybersecurity? Also, how it can help us in securing the safety of our company information data.
What Is Cybersecurity?
Cybersecurity is the protection of networks, computers, programs, and data from cyber threats.
The scope of cybersecurity is broad and includes defense from intentional, criminal, or accidental harm. We will make it simple and gain more knowledge about cybersecurity terms and structure.
Cybersecurity is a large subject, and there are many different approaches to cybersecurity management. The standard definition of cybersecurity is the protection of information from unauthorized access or use or unauthorized modification.
Three key concerns for cybersecurity are confidentiality, integrity, and availability. This definition is generally accepted in the international community.
Cybersecurity can encompass a range of activities. So it is from computer system protection to communications security and from physical security to cryptography.
The field has been evolving over decades as computing technology evolves. Most contemporary definitions of cyber security have been written since around 2010.
Cybersecurity is a complex and ever-evolving field. So there are many terms related to cybersecurity.
Cyber Threat Intelligence (CTI)
It is the practice of collecting, analyzing, and distributing information about cyber threats. It enables organizations to understand and defend themselves against their adversaries.
Cyber Threat Intelligence
It is a form of intelligence that addresses cyber threats. Cyber threat intelligence is a subset of wider threat intelligence.
Threat intelligence can be used to detect and counter cyber threats and improve an organization’s overall security posture.
Computer Security Incident
A computer security incident is any violation or imminent threat of violation of computer security policies, acceptable use policies, or standard security practices.
The term “incident” refers to an event that actually or potentially jeopardizes the confidentiality, integrity, or availability of an information system. Also, it is data such that it should be considered a security incident.
The term “incident” does not refer to an event that affects only the availability of a system or its data; that is a service disruption. Similarly, the term “incident” does not refer to an activity that violates a policy.
But does not threaten the confidentiality, integrity, and availability of an information system.
For instance, non-disclosure agreements do not by themselves constitute information system security incidents. It is unless there is also evidence of unauthorized access or disclosure or another computer misuse.
An incident should be reported if it results in actual harm to organizational operations. So it could include mission, functions, image, or reputation. In addition, it could include individual members, such as employees, customers.
A potential threat that has not yet been verified as having occurred should not be reported as an incident. Unless it has been verified as likely to occur and cause harm.
For instance, if an intrusion detection system detects numerous attempts at unauthorized access.
The practice of cybersecurity requires strong knowledge in many different areas. Some skills are highly technical while others require strong management skills.
Computer Security Incident Response Team (CSIRT)
Computer security incident response teams are organizations that are responsible for handling computer security incidents. CSIRTs are also known as incident response teams.
A computer security incident response team is an organization or group of people who are responsible for handling computer security incidents. So it is the responsibility of the team to investigate computer security incidents discovered by the organization.
Also, they are responsible for taking corrective measures after an investigation. CSIRTs are also known as incident response teams.
Some countries have special Computer Emergency Response Teams which can also be called on to handle more serious incidents.
