"Information security, sometimes shortened to InfoSec, is the practice of protecting information by mitigating information risks."
The study of techniques used to protect confidential and sensitive information from unauthorized access or disclosure.
Threats and Attack Types: Understanding the different types of threats and attacks that can occur.
Security Policy and Governance: Developing security policies and procedures to safeguard data and systems.
Risk Management: Evaluating and managing risks to reduce potential loss and damage.
Access Control and Authentication: Methods to control user access and ensure proper identification.
Incident Response: Procedures to respond and recover from security incidents.
Cryptography: Techniques for safeguarding data transmission and storage.
Network Security: Protecting networks from threats and attacks.
Application Security: Ensuring security of applications and software.
Physical Security: Physical protection of facilities and equipment.
Security Assessment and Testing: Methods to evaluate security and test for vulnerabilities.
Compliance and Regulations: Meeting regulatory requirements and industry standards.
Cloud Security: Security concerns and measures for cloud computing.
Mobile Security: Security considerations and strategies for mobile devices.
Forensics and Investigation: Techniques for computer forensics and investigation.
Threat Modeling: Assessment of potential threats and vulnerabilities in a system or network.
Access Control: Used to restrict access to certain resources by authenticating and authorizing user access based on predefined security policies.
Application Security: This type of security is designed to protect enterprise applications from unauthorized access, modification, or attacks.
Cloud Security: Cloud security is an umbrella term that covers all types of security measures that are implemented to protect cloud data and applications against unauthorized access, data breaches, and other malicious activities.
Compliance & Regulatory Security: The compliance and regulatory framework involves adhering to the rules, regulations, and industry standards that govern how sensitive data is stored, accessed, and processed.
Cryptography: This technology involves the use of mathematical algorithms to ensure the confidentiality and integrity of data.
Data loss prevention: DLP is a set of tools and techniques that mitigate the risks associated with data breaches and unauthorized data access.
Identity & Access Management: IAM encompasses all processes and tools involved in the creation, management, and securing of user identities and access across all IT resources.
Incident Response: Incident response involves the detection, analysis, and mitigation of security incidents and breaches.
Information Security Governance: The governance process involves all policies, procedures, and guidelines set by an organization to ensure the effective management of information security risks.
Mobile Security: This category of security techniques involves the protection of mobile devices and applications against malware, hacking, and other attacks.
Network Security: Network security is concerned with safeguarding data that is transmitted over networks, including the internet.
Physical Security: Physical security is concerned with protecting physical assets against theft, damage, or other malicious activities.
Risk Management: This involves identifying, tracking, analyzing, and mitigating information security risks.
Secure Communications: Secure communication techniques such as encryption or VPNs are used to secure data transmission between parties over an insecure channel.
Social Engineering: Social engineering attacks exploit human psychology to gain access to IT systems, with the goals of stealing data or gaining unauthorized access.
Web Security: Web security includes all security measures that are implemented to protect web-based applications and services against malicious attacks.
"It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information."
"Protected information may take any form, e.g., electronic or physical, tangible (e.g., paperwork), or intangible (e.g., knowledge)."
"Information security's primary focus is the balanced protection of data confidentiality, integrity, and availability (also known as the CIA triad) while maintaining a focus on efficient policy implementation, all without hampering organization productivity."
"This is largely achieved through a structured risk management process that involves identifying information and related assets, plus potential threats, vulnerabilities, and impacts; evaluating the risks; deciding how to address or treat the risks, i.e., to avoid, mitigate, share, or accept them; where risk mitigation is required, selecting or designing appropriate security controls and implementing them; and monitoring the activities and making adjustments as necessary to address any issues, changes, or improvement opportunities."
"To standardize this discipline, academics and professionals collaborate to offer guidance, policies, and industry standards on passwords, antivirus software, firewalls, encryption software, legal liability, security awareness and training, and so forth."
"This standardization may be further driven by a wide variety of laws and regulations that affect how data is accessed, processed, stored, transferred, and destroyed."

"However, the implementation of any standards and guidance within an entity may have limited effect if a culture of continual improvement is not adopted."
"It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data."
"It also involves actions intended to reduce the adverse impacts of such incidents."
