Cybersecurity: Part of the Development Process

Security is an important part of the development process and security considerations should be taken into account during the process, not after it is completed.

CIA Triad: Confidentiality

In Cybersecurity, Confidentiality is the pillar of the CIA triad which refers to the principle that only those who should have access to information can access it.

CIA Triad: Integrity

In Cybersecurity, Integrity is the pillar of the CIA triad which refers to the principle that data is what we expect it to be.

In other words, data should not be able to be edited by unauthorized parties.

CIA Triad: Availability

In Cybersecurity, Availability is the pillar of the CIA triad which refers to the principle that data is reliably available.

Security Principle: CIA Triad

One of the most important security principles is the CIA triad, which stands for Confidentiality, Availability, and Integrity.

Data Loss

Data loss is when data becomes temporarily or permanently unavailable.

Data Breach

A data breach is when data is intentionally or accidentally accessed by an unauthorized party.

This is an example of a violation of the Confidentiality pillar in the CIA Triad.

Data Exfiltration

Data exfiltration is the intentional, unauthorized transfer of data to an external party.

This is an example of a violation of the Confidentiality pillar in the CIA Triad.

Vulnerability Impacts

Cybersecurity vulnerabilities can potentially result in data loss, identity theft, and financial and reputational damage.

The average cost of a data breach was 3.86 million dollars", "Having an incident response team and a tested incident response plan saved companies an average of 2 million dollars", "Lost business is the biggest source of cost to an organization that suffers a breach", "Malicious attacks caused 52 percent of data breaches, human error caused 23 percent, and system glitches caused the remaining 25 percent
