Information security is the practice of preventing unauthorized access, use, disclosure, disruption, modification, or destruction of information. It involves a multi-layered approach to safeguard data and systems.
Key Characteristics / Core Concepts
- Confidentiality: Ensuring only authorized individuals can access sensitive information.
- Integrity: Maintaining the accuracy and completeness of data, preventing unauthorized modification.
- Availability: Guaranteeing reliable and timely access to information and resources for authorized users.
- Authentication: Verifying the identity of users before granting access.
- Authorization: Defining what actions authenticated users are permitted to perform.
How It Works / Its Function
Information security relies on a combination of technical, administrative, and physical safeguards. Technical controls include firewalls, encryption, and intrusion detection systems. Administrative controls encompass policies, procedures, and training programs. Physical security involves measures like access controls and surveillance.
Examples
- Using strong passwords and multi-factor authentication to protect online accounts.
- Installing antivirus software and regularly updating it to prevent malware infections.
- Implementing data encryption to protect sensitive information during transmission and storage.
