"Computer security, cyber security, digital security or information technology security (IT security) is the protection of computer systems and networks from attacks by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide."
An overview of Cybersecurity concepts, threats, and defenses.
Information security: Information security refers to the practice of protecting information from unauthorized access, use, disclosure, disruption, modification, or destruction.
Network security: Network security is a process of taking physical and software-based measures to protect the underlying networking infrastructure from unauthorized access, misuse, malfunction, modification, or destruction.
Cybercrime: Cybercrime refers to the criminal activities that are carried out through the use of a computer or other electronic communication devices and the internet.
Cryptography: Cryptography is the practice of securing communication by converting plain text into ciphered text, so that it can only be read by authorized parties who have the key to decode it.
Risk management: Risk management is the process of identifying, assessing, and controlling risks that may affect an organization's resources, assets, and operations through IT or Information Security.
Cybersecurity laws: Cybersecurity laws refer to the regulations and guidelines developed by governing bodies worldwide that mandate cybersecurity policies, implementation of security measures, and the penalties for violating them.
Mobile device security: Mobile device security is the process of protecting mobile devices from unauthorized access or misuse.
Cloud security: Cloud security refers to the practice of securing networks, servers, applications, and data, that are hosted in cloud computing environments.
Incident response: Incident response is a structured approach used to manage and respond to security incidents.
Threat intelligence: Threat intelligence is the process of gathering, analyzing, and distributing information about potential threats and risks to an organization.
Vulnerability Assessment: Vulnerability assessment refers to the process of identifying vulnerabilities in the system or network and determining the severity and potential of those vulnerabilities.
Penetration testing: Penetration testing refers to the process of simulating a real-world attack on a system or network to identify vulnerabilities that can be exploited by attackers.
Endpoint security: Endpoint security refers to the protection of endpoints, such as laptops, desktops, and mobile devices that are used to access a network or system, against cyber threats.
Cybersecurity frameworks: Cybersecurity frameworks are a set of guidelines or principles used to manage and improve an organization's cybersecurity posture.
Security Operations Center (SOC): Security Operations Center is a centralized unit within an organization responsible for monitoring and responding to security incidents.
Multi-factor authentication: Multi-factor authentication refers to the process of verifying a user's identity by using two or more different authentication methods.
Identity and Access Management (IAM): Identity and Access Management (IAM) is the process of controlling access to an organization's resources and data by granting or denying privileges to users.
Security information and event management (SIEM): Security Information and Event Management (SIEM) is an approach to security management that combines security information management and security event management to provide a comprehensive view of an organization's security posture.
Cybersecurity training: Cybersecurity training refers to the education and awareness programs designed to help employees of an organization understand the cybersecurity threats and how to respond to them.
Security policies and procedures: Security policies and procedures are guidelines or rules developed by an organization to protect its assets, resources, systems, and data from unauthorized access, use, or disclosure.
Networking and Security Basics: This type of introduction to cybersecurity covers the fundamentals of networking, including the OSI model, IP addressing, and network topologies. It also includes basic security concepts, such as authentication, encryption, and firewalls.
Cybersecurity Tools and Techniques: This introduction to cybersecurity focuses on the tools and techniques used to secure networks and systems. It covers topics such as vulnerability scanning, penetration testing, and incident response.
Information Security Management: This introduction to cybersecurity covers the management of information security within an organization. It includes topics such as risk management, security policies and procedures, and compliance regulations.
Digital Forensics: This type of introduction to cybersecurity covers the investigation of computer systems, networks, and digital devices for evidence of cybercrime. It includes techniques such as data acquisition, analysis, and preservation.
Ethical Hacking: This type of cybersecurity introduction covers the ethical use of hacking techniques to identify and remediate security vulnerabilities in networks and systems.
Cyber Threat Intelligence: This type of introduction to cybersecurity covers collecting and analyzing data to identify potential threats and vulnerabilities in networks and systems.
Cryptography: This type of cybersecurity introduction covers the principles of encryption and decryption techniques to protect data and the communication channels.
Social Engineering and Human Factors: This type of introduction to cybersecurity studies the techniques used by cybercriminals to manipulate human behavior and the psychosocial factors that influence this behavior.
Physical Security: This type of cybersecurity introduction covers protecting physical assets, such as data centers and critical infrastructure, from cyber attacks.
Mobile Security: This type of introduction to cybersecurity covers securing mobile devices and applications, such as smartphones and tablets, to prevent data breaches and cyber attacks.
