What is information security?  Information security is the process of protecting information. It protects its availability, privacy and integrity from unauthorized access, use, disclosure, disruption, modification or destruction.

Components  Confidentiality  Integrity  Availability

 Confidentiality is the term used to prevent the disclosure of information to unauthorized individuals or systems.  Integrity means that data cannot be modified without authorization.  Availability means that the computing systems used to store and process the information, the security controls used to protect it, and the communication channels used to access it must be functioning correctly.

Types Of Security  Data security  Computer security  Network security

Data Security  It is the means of ensuring that is kept safe from corruption and that access to it is suitably controlled. Thus data security helps to ensure privacy. It also helps in protecting personal data.

Data Security Technologies Disk Encryption Backups Data Masking Data Erasure

 Data Encryption refers to encryption technology that encrypts data on a hard disk drive. Spoiled hard disk  Backups are used to ensure data which is lost can be recovered

 Data masking of structured data is the process of obscuring specific data within a database table or cell to ensure that data security is maintained and sensitive information is not exposed to unauthorized personnel.  Data Erasure is a method of software-based overwriting that completely destroys all electronic data residing on a hard drive or other digital media to ensure that no sensitive data is leaked when an asset is retired or reused.

Threat  There are people who make a living from hacking or breaking through information security systems.  They use their technological skills to break into computer systems and access private information.  Through Phishing.

Measures  Simple security measures can be used by everyone to keep data secure. Changing passwords on your computer, and using combinations of letters and numbers, makes it harder for hackers to gain access.  Technology implementing higher levels of information security, such as iris recognition systems, security systems should keep them out for a little longer.  Choosing Good Passwords.  Physical Security.  Avoid Phishing

Conclusion  It is the ongoing process of exercising due care and due diligence to protect information, and information systems, from unauthorized access, use, disclosure, destruction, modification, or disruption or distribution.  This never ending process involves ongoing training, assessment, protection, monitoring & detection, incident response & repair, documentation, and review.
