INFORMATION SECURITY Meaning and
Definition
-
Information security refers to the practices and measures taken to protect information from unauthorized access, disclosure, disruption, modification, or destruction. It encompasses the strategies, policies, procedures, and technologies implemented to maintain the confidentiality, integrity, and availability of information. Information security involves safeguarding both electronic and physical information, regardless of its form (e.g., digital files, printed documents, databases, or communication channels).
The goal of information security is to prevent unauthorized individuals or entities from gaining access to sensitive information, such as personal data, financial records, intellectual property, or classified information. It also aims to ensure the accuracy, authenticity, and reliability of information, as well as its availability to authorized users whenever needed.
To achieve information security, various techniques are employed, including encryption, access controls, firewalls, intrusion detection systems, antivirus software, and security protocols. Organizations often establish information security management systems and policies to assess risks, establish guidelines, and provide training to employees on how to handle information securely.
Information security is crucial in modern society due to the increasing reliance on technology and the growing threat landscape. Breaches in information security can lead to financial loss, reputational damage, legal consequences, privacy violations, or even compromise national security. Therefore, individuals, organizations, and governments must pay attention to information security to ensure the protection of sensitive and valuable information from unauthorized access or misuse.
Etymology of INFORMATION SECURITY
The word "information security" has its etymology rooted in Latin and Old French.
The term "information" comes from the Latin word "informare", which means "to give form to" or "to shape". Over time, "informare" evolved into the Old French term "informacion", which referred to the act of giving instruction or teaching someone.
The word "security" originates from the Latin word "securitas", derived from "securus", meaning "free from care" or "free from anxiety". It was often used in reference to safety and protection.
The combination of these origins led to the phrase "information security", which refers to the practice of protecting important or sensitive information from unauthorized access, use, disclosure, disruption, modification, or destruction.
