"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."
The protection of computer systems and networks from theft, damage, or unauthorized access.
Network Security: Protecting network systems from unauthorized access, misuse, and modification.
Cryptography: The art and science of concealing data by encoding it into different forms.
Authentication and Authorization: The process of verifying the identity of a user and granting access to resources based on their level of authorization.
Malware Analysis: The study of malicious software and how to detect, analyze, and respond to it.
Penetration Testing: The practice of simulating attacks on a network or system to identify vulnerabilities and weaknesses.
Incident Response: The process of responding to security incidents, from identifying to containing and mitigating the impact.
Cloud Security: Ensuring the security of data and applications in cloud-based environments.
Mobile Security: Protecting mobile devices and applications from malware, theft, and unauthorized access.
Social Engineering: Manipulating individuals to reveal confidential information or perform fraudulent acts.
Risk Management: Identifying, assessing, and prioritizing security risks and implementing controls to mitigate them.
Network security: Involves protecting computer networks and their components from unauthorized access, cyberattacks, and other security threats.
Application security: Focuses on securing computer systems, applications, and software from potential cybercrime activity.
Endpoint security: Deals with securing individual devices such as smartphones, laptops, and desktops from cyberattacks and other outside attacks to prevent data loss and breaches.
Database security: Involves protecting databases and data storage systems from unauthorized access, cyberattacks, and other security threats.
Cloud security: Covers the security of cloud computing platforms and the data and information that is stored, accessed, and transmitted within them.
Industrial control system security: Deals with protecting critical infrastructure and systems from cyberattacks, such as power grids and water supply systems.
Internet of Things (IoT) security: Concerned with securing internet-connected devices from vulnerabilities that can be exploited by cybercriminals.
Incident response and recovery: The process of identifying and responding to cyberattacks, mitigating damages, and restoring services and infrastructures.
Physical security: Focuses on protecting physical network infrastructures, data centers, and other critical facilities from security threats.
Social engineering: The process of using human psychology to manipulate and trick people into giving away sensitive information or access to secure systems.
