- 9. Confidentiality Encryption Encryption is amethod of transforming information to make it unreadable for unauthorized users by using an algorithm. The transformation of data uses a secret key (an encryption key) so that the transformed data can only be read by using another secret key (decryption key). Asymmetric-key Symmetric-key

- 11. Confidentiality Access Control Access controldefines rules and policies for limiting access to a system or to physical or virtual resources. It is a process by which users are granted access and certain privileges to systems, resources or information. In access control systems, users need to present credentials before they can be granted access such as a person's name / badge or a computer's serial number.
- 13. Confidentiality Authentication Authentication is aprocedure that guarantees and affirms a client's character or job that somebody has. It tends to be done in various ways, yet it is typically founded on a blend of- ▪something the individual has (like a smart card or a radio key for putting away mystery keys). ▪something the individual knows (like a secret key/password), ▪something the individual is (like a human with a biometric (fingerprint/retina/face geometry)).
- 14. Confidentiality Authorization Authorization is asecurity mechanism which gives permission to do or have something. It is used to determine a person or system is allowed access to resources, based on an access control policy, including computer programs, files, services, data and application features. It is normally preceded by authentication for user identity verification.
- 15. Confidentiality Physical Security Physical securitydescribes measures designed to deny the unauthorized access of IT assets like facilities, equipment, personnel, resources and other properties from damage. It protects these assets from physical threats including theft, vandalism, fire and natural disasters.
- 16. Integrity Backups Backup is theperiodic archiving of data. It is a process of making copies of data or data files to use in the event when the original data or data files are lost or destroyed. It is also used to make copies for historical purposes, such as for longitudinal studies, statistics or for historical records or to meet the requirements of a data retention policy.
- 17. Integrity Check-Sums A checksum isa numerical value used to verify the integrity of a file or a data transfer. In other words, it is the computation of a function that maps the contents of a file to a numerical value. They are typically used to compare two sets of data to make sure that they are the same. A checksum function depends on the entire contents of a file. It is designed in a way that even a small change to the input file (such as flipping a single bit) likely to results in different output value.

- 19. Integrity Data Corrective Codes Itis a technique for storing information so that little changes can be effectively distinguished and consequently remedied.
- 20. Availability Physical Protections Computational Redundancies -Physicalsafeguard means to keep information available even in the event of physical challenges. It ensure sensitive information and critical information technology are housed in secure areas. -It is applied as fault tolerant against accidental faults. It protects computers and storage devices that serve as fallbacks in the case of failures.

- 22.
- 23. Role Hence, in eachand every aspect of information technology, be it hardware, software, cloud, platform, we need cybersecurity to get ourselves out of the vulnerability of data thefts and misuses. Cybersecurity is the only field that can ensure that our data is safe and transmitted within the secured and monitored protocols. Security breakers or crackers (popularly known as hackers) are consistently creating new cyber attacks to find backdoors or traps to go inside or get access to a system or its data for some negative purposes. The main role of cybersecurity id to constantly find those attacks, decipher them and continuously maintain the integrity of user data.
- 24. Career Opportunities Cyber securityprofessionals, or information security analysts, have a wide range of responsibilities. Cyber security careers are complex and many roles can be found with banks, retailers and government organizations. On the job, you can expect to safeguard an organization's files and network, install firewalls, create security plans and monitor activity. If a breach occurs, you'll be responsible for identifying the problem and finding a solution quickly. Because of the frequency of cyber attacks, careers are varied and qualified professionals are in demand.
