Git

<versioning control />

distributed version control system primarily used for tracking changes in source code during software development.

by Linus Torvalds in 2005

the concept: stream of snapshot

What is...

different between others.. ?

Git basically takes a picture of what all your files look like at that moment and stores a reference to that snapshot. To be efficient, if files have not changed, Git doesn’t store the file again, just a link to the previous identical file it has already stored.

commit SHA : 67b70ef8c1929ec2214a8d92506fd3fc6d98ac1b

Hows that Work...

git flows

commited SHA : 67b70ef8c1929ec2214a8d92506fd3fc6d98ac1b

commited SHA is reference by small thing of changes and become a new snapshot.

Reproduce...

standart versioning

development

staging / pre-prod / (uat/sit) / testing

production / stable / Release / LTS

Q-A/C

<Quality Assurance or Control />

QA aims to prevent defects from occurring by focusing on improving processes and systems.
QC focuses on ensuring the final product or system meets quality standards and users expectations.

Quality Assurance/Control.... ?

Sonarqube

STest

<Stress Testing />

a method used to assess the performance and stability of a system or application under extreme conditions or workloads.

What is...

Stress Testing.... ?

Pros:
- Identifies System Limits
- Reveals Bottlenecks
- Prepares for Peak Usage

Cons:
- May Cause Downtime
- Resource Intensive (High load resources)

The Pro's and Cons

Pentest

<Penetration Testing />

is a simulated cyberattack against a system to evaluate its security. The goal is to identify and exploit vulnerabilities before malicious attackers can do so.

What is...

Penetration Testing.... ?

- Identify vulnerabilities
- Assess the impact
- Test the effectiveness
- Provide actionable insights

Objective

Penetration Testing.... ?

- SQLinjectoin
- Cross Site Scripting (XSS)
- Un-validated Form Control
- Leak Permissions (777)
- Misleading Code-Logic

Common Case
