Data Security

• Data Security is a way by which we can protect our 
database, Companies and Websites from unauthorized 
access and destructive forces.

• We can protect our database from unwanted actions like 
cyber attack and data breach.

• Data Security also known as Information Security and 
Computer Security.


CIA Triad

• Confidentiality, integrity and availability are called CIA 
triad also known as AIC triad.

• These  Elements are the components of Security.
• These are the guide policies for  information security or 

Data Security Within Organization.


• Data is available for all the time and we can easily access 
the data when ever we want.

• Data is only available to authorized users means only 
authorized users have right to access the data.

• We Have all information like Who accessed the data and 
What data accessed.

Availability


• Verify that user is Authorized or not means Verify  
Username and Password with Database.

• Only Authorized user can edit the data.
• Verify all the request which are coming from Authorized 

users cause in some organization users have right to 
access limited no of  database, some users have right to 
access all database.

Authenticity


Integrity

• Check that there is no change in database.
• Suppose UserA send “ABC” data to UserB, We need to 

ensure that UserB receive “ABC” data not other data, 
Data should be received as it is without any modification.

• Report all changes which happen by Authorizes users.


Confidentiality

• Data should be confidential means If UserA sends some 
data to UserB than only UserB received that data not 
anyone else able to see data.

• What ever Information flow in network no one is able to 
see that, except the receiver. 

• Confidentiality is important cause if we are sending some 
important file to the receiver and that data is accessed by 
some other person, this things can be harmful for our 
company.


Technologies for Data Security

• Data Security is a way by which we can protect our 
database, Companies and Websites from unauthorized 
access and destructive forces.

• We can protect our database from unwanted actions like 
cyber attack and data breach.

• Data Security also known as Information Security and 
Computer Security.

 Data Encryption:-


Backup of Data

• Backup is important cause if in any case we lost our data 
back up is the only option by which we can recover our 
data.

•  Now a days Every Company is following the process of 
backup.

• It is important to keep your files backup cause if in any 
case someone do some changes then you can get the 
original copy from backup.


 Data Masking 

• We can hide Original data with the help of Data Masking.
• Data is classified as personal identifiable data, personal 

sensitive data or commercially sensitive data which we 
can protect by applying masking.


 Data Erasure 

• It is a software base overwriting.
• Data Erasure destroy all Electronic data which is store in 

Hard Disk or any Digital Media by doing this No 
sensitive data lost when we reused the assets.
