"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 study of protecting computer networks and systems from theft or damage to their hardware, software, or electronic data.
Cyber Threats: Understanding different types of cyber threats, such as malware, phishing, ransomware, etc. is crucial for recognizing attacks and devising appropriate countermeasures.
Information Security: Concepts related to securing data, digital storage, and network connections, including encryption, access control, and firewalls.
Cybersecurity Governance: Understanding the legal and regulatory frameworks that govern cybersecurity, including national and international policies and procedures.
Cybersecurity Management: Strategies for managing cybersecurity risks, including identifying potential threats, developing response plans, and implementing disaster recovery procedures.
Network Security: Understanding the components of a secure network, including protocols, standards, and best practices for securing network architecture.
Incident Response: Responding to cyber incidents, including forensic analysis, tracking network usage, and managing operations during a crisis.
Penetration Testing: Testing the security of your IT infrastructure and network through ethical hacking and vulnerability testing.
Cybersecurity Economics: Analyzing the economic impact of cybersecurity, including the costs of attacks and the ROI of cybersecurity defenses.
Cybersecurity Metrics: Collecting and analyzing data on cybersecurity incidents and trends to make informed policy and budgetary decisions.
Cybersecurity Education and Awareness: Providing training and education for employees, customers, and other stakeholders, to improve cybersecurity awareness and best practices.
Network security: Protecting networks from unauthorized access and building measures to prevent cyberattacks.
Application security: Securing applications from attacks and vulnerabilities.

Cloud Security: Safeguarding data stored in cloud platforms from unauthorized access.
Mobile Security: Protecting mobile devices and applications from threats.
Data Security: Protecting data in motion and at rest.
Identity and Access Management (IAM): Maintaining a careful track of user rights and permissions, so that only authorized individuals can access specific systems.
Operational Security: Making sure that all business processes are secure.
Disaster Recovery: Planning for the worst-case scenarios of cyberattacks and ensuring the business can recover.
Physical Security: Securing networks, devices, servers, and data centers by controlling entry into the building or room.
Geopolitical Cybersecurity: Focusing on the security of governments or countries by securing their critical infrastructure, sensitive communications, and intellectual property.
Social Engineering Cybersecurity: Protecting employees from hackers who exploit human behavior and characteristics to gain unauthorized access to sensitive data.
