Identify security services for data communication and write their names with reasons why you have chosen? b) Ali is converting each bit of data packets using 1-bit chipping technique
Question 4. Identify security services for data communication and write their names with reasons why you have chosen?
b) Ali is converting each bit of data packets using 1-bit chipping technique
first let's understand why we need security services while communicating.
Whenever communication happens over network, the data become vulnerable. the possibility of tracking the data by third party and hacking or modifying the data is main issue. that is why, security must be provided.
To provide security to data, there are some security services which must be applied. They are-
1. Confidentiality of data
In simple terms, it keeps data private. no third party user can access the data without authority.
2. Integrity of data
Suppose i have sent salary information over network, then it must received as i send. otherwise if someones salary mentioned on someone else name, then it has no use. data integrity is applied for that purpose. the data sent by sender should exactly match with receivers data.
3. Authentication and authority
Authentication is basic step performed to ensure security. Today, for every application there is two factor authentication provided so that only authorized user can access the data
4. non repudiation
It simply contain all the proofs of safe delivery
5. Access control
This is mainly added for hardware access. access of device is given to only authorized one.
