There are many security services which are as follows −
Message Confidentiality −
Computer Security Service is the process of preventing theft, damage, and unauthorized use of data and computer systems. The confidentiality principle states that the only people who should be able to produce a message element are the sender and the intended receiver. It guards against passive attacks on the sent data.
Depending on the nature of the information to be conveyed, confidentiality can be used on a number of levels. The following are the several categories of confidentiality:
Connection Confidentiality − The defense of every user’s data over a connection.
Connectionless Confidentiality − The safety of every user’s data within a specific data block.
Traffic-flow Confidentiality − The safeguarding of the data that can be obtained by watching traffic patterns.
The likelihood that a connection is authentic is what the authentication service is concerned with. The purpose of the authentication service is to convince the recipient that a single communication, such as a warning or alarm signal, is coming from the source it claims to be.
By not recanting a sent message, neither the sender nor the recipient can be adversely affected. As a result, upon message delivery, the recipient can verify that the claimed sender truly sent the message.
Similarly, upon receipt of a communication, the sender has the ability to verify that the designated recipient has indeed received it.
Access Control −
Who should be able to access a system or information through a communication channel is determined by the access control principle. It encourages refraining from using a resource without authorization.
Data Integrity −
Data integrity is intended to prevent any party from changing, adding, removing, or rehashing information. Data integrity can be applied throughout a message’s flow, to a single message, or to a specific section within a message. Complete stream protection can be supported by data integrity.

There are various types of data integrity which are as follows −
Link integrity with recovery – It ensures that all user data on a connection is accurate and detects any tampering, additions, deletions, or replays of data across the entire sequence, with an attempt at recovery.
integrity of the connection without recovery – it only allows for detection, not recovery.
The concept of selective areas inside user information of a data block shared across a connection is supported by selective-field connection integrity, which establishes a decision-making form for whether the selected fields have been altered, added, deleted, or replayed.
Connectionless integrity – This refers to the ability to identify changes made to data and supports the integrity of a single connectionless data block. Furthermore, the type of replay detection that can be offered is restricted.
Connection-less selectable-field integrity – It takes the form of determining whether the selected areas have been altered and supports the integrity of chosen fields within a single connection-less data block.
Q. What exactly is a Computer Security Service?
Ans: Computer security is the process of guarding against theft, unauthorized access, abuse, loss of data, and other security-related problems with computers and the networks, software, hardware, and data they are connected to.
Q. Are computer security services only for businesses?
Ans: Computer security services come in a variety of forms and can be provided through consulting or within an organization, depending on the needs of the client or business.
Q. Can I rely solely on antivirus software for protection?
Ans: Antivirus software is not always effective against novel versions and is limited to identifying recognized threats. Operating systems are inaccessible to antivirus software, allowing browser-based attacks to get past them. These attacks use malicious scripts and malware to infiltrate your device.
