This section is to provide a deep understanding of the foundation of security with the well-known triad CIA, hey it's not a Central Intelligence Agency, this CIA referred to as Confidentiality, Integrity, and anonymity. To avoid confusion, we can refer to it as the AIC triad.

The CIA triad is the most common principle to assess, select and implement the proper security controls to reduce risk.

1) Confidentiality

Making sure that your sensitive information is accessible to authorized users and ensuring no data is disclosed to unintended ones. For example, your password is confidential and shall not be shared who might exploit it which eventually hampers Confidentiality.

Methods to ensure Confidentiality:

1. Data encryption
2. Two or Multifactor authentication
3. Verifying Biometrics

2) Integrity

Ensuring all your data is accurate; reliable and it must not be altered in the transmission from one point to another.

Methods to ensure Integrity:

1. No unauthorized shall have access to delete the files, which breaches confidentiality also. So, there shall be User Access Controls.
2. Proper backups must be available to restore immediately.
3. Version controlling must be there to check the log who has modified.

3) Availability

Whenever the user has requested a resource for a piece of information there shall not be any attack warnings such as Denial of Service (DoS). All the information has to be available. For example, a website is under the hands of hackers resulting in the DoS so there hampers the availability.

Methods to ensure Availability:

1. Spare equipment like firewalls, proxy servers on the downtime which can guard.
2. Storing backup at a geographically isolated location.
3. Having a DR plan, Disaster recovery plan.
