Solution

Confidentiality, integrity and handiness, additionally called the Central Intelligence Agency triad, could be a model designed to guide policies for info security at intervals a company.

Confidentiality could be a set of rules that limits access to info, integrity is that the assurance that the knowledge is trustworthy and correct, and handiness could be a guarantee of reliable access to the knowledge by licensed individuals.

•           Confidentiality:

Confidentiality is roughly adore privacy. Measures undertaken to confirm confidentiality area unit designed to forestall sensitive info from reaching the incorrect individuals, whereas ensuring that the correct individuals will in reality get it: Access should be restricted to those licensed to look at the info in question. it\'s common, as well, for knowledge to be categorised in step with the number and sort of injury that might be done ought to it comprise inadvertent hands. additional or less demanding measures will then be enforced in step with those classes.

•           Integrity:

Integrity involves maintaining the consistency, accuracy, and trait of information over its entire life cycle. knowledge should not be modified in transit, and steps should be taken to confirm that knowledge can not be altered by unauthorized individuals (for example, in an exceedingly breach of confidentiality). These measures embody file permissions and user access controls. Version management perhaps wont to forestall incorrect changes or accidental deletion by licensed users changing into a drag. additionally, some suggests that should be in situ to sight ANy changes in knowledge which may occur as a results of non-human-caused events like an magnetic attraction pulse (EMP) or server crash. Some knowledge would possibly embody checksums, even cryptologic checksums, for verification of integrity. Backups or redundancies should be obtainable to revive the affected knowledge to its correct state.

•           Availability:

Availability is best ensured by strictly maintaining all hardware, playing hardware repairs straight off once required and maintaining a properly functioning OS atmosphere that\'s freed from computer code conflicts. It’s additionally vital to stay current with all necessary system upgrades. Providing adequate communication information measure and preventing the prevalence of bottlenecks area unit equally vital. Redundancy, failover, RAID even high-availability clusters will mitigate serious consequences once hardware problems do occur. quick and adaptative disaster recovery is important for the worst case scenarios; that capability is dependent on the existence of a comprehensive disaster recovery arrange (DRP). Safeguards against knowledge loss or interruptions in connections should embody unpredictable events like natural disasters and fireplace. to forestall knowledge loss from such occurrences, a backup copy is also hold on in an exceedingly geographically-isolated location, maybe even in an exceedingly fireproof, waterproof safe. additional security instrumentality or computer code like firewalls and proxy servers will guard against period and unaccessible knowledge attributable to malicious actions like denial-of-service (DoS) attacks and network intrusions.
