"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 attack.
Information Security: Involves the protection of information through the use of security policies, procedures, and techniques to ensure its confidentiality, integrity, and availability.
Network Security: A type of cybersecurity that deals with securing a computer network, which can include securing routers, switches, and firewalls.
Incident Response: Also known as an IT incident management system, it is a set of procedures for detecting, alerting, and responding to security breaches or incidents.
Risk Management: Involves identifying, assessing, and mitigating risks to security systems, data, and processes.
Computer Forensics: The investigation and analysis of digital devices, data, and networks in order to gather evidence for legal or other purposes.
Access Control and Authentication: Involves the management of access to systems and data, as well as the authentication of users and devices.
Cryptography: The practice of secure communication through the use of codes and ciphers.
Security Architecture and Design: The process of designing and implementing security solutions that meet specific business needs.
Security Governance, Risk Management, and Compliance: A framework that provides a systematic approach to assessing and managing security risks, and ensuring compliance with regulatory requirements and industry standards.
Operational Security: The practice of implementing security controls and measures that address the day-to-day operations of an organization.
Physical Security: The physical protection of systems and assets, usually in the form of access control, surveillance, and monitoring.
Web Application Security: A specific area of cybersecurity that deals with securing web-based applications, including web portals, online stores, and websites.
Malware Analysis: The process of analyzing and dissecting malicious software in order to identify its source, purpose, and potential harm.
Social Engineering: The use of psychological manipulation to gain unauthorized access to information or systems.
Vulnerability Assessment and Penetration Testing: The process of assessing the security of a system or network by simulating an attack and identifying vulnerabilities that could be exploited.
Information security: It involves protecting sensitive data and information from unauthorized access, theft, manipulation, and destruction.
Network security: It focuses on securing computer networks from threats such as hacking, phishing, malware, and other forms of cyberattacks.
Application security: It involves securing software applications from hacking, unauthorized access, and misuse.
Cloud security: It focuses on securing data and applications that are stored on cloud platforms or accessed through the cloud.
Operational security: It involves managing risks associated with the day-to-day operations of an organization, including physical security, personnel security, and other non-technical security measures.
Cyber intelligence: It involves gathering and analyzing information on cyber threats to provide insights and support security operations.
Incident response and management: It involves establishing protocols and procedures to address security breaches, cyberattacks, and other incidents.
Identity and access management: It involves managing user identities and access to systems, networks, and data to prevent unauthorized access and misuse.
Cryptography: It involves securing data by converting it into a code that can only be read by authorized parties.
Physical security: It involves securing physical access to critical infrastructure, data centers, and other facilities to prevent physical breaches that could result in data theft, equipment damage, or other forms of harm.
