Introduction to web application security

Section 1: Why is Application Security Important?

Application security is a unique and challenging undertaking. It is important to stress that it is absolutely critical in today's world. Applications that manage valuable data are increasingly exposed to potential attackers.

Security Breaches and Vulnerabilities

The critical nature of application security in today's world is evinced daily in the news. Every day brings news of a newly-discovered vulnerability in popular software or operating systems, a new style of attack that results in the successful breaching of an organization's systems, the discovery of malware in government computer systems...a seemingly endless stream of "bad news." Indeed, such news will never end. The motivation for many attacks now is financial, and an attacker with a profit motive will not simply go away. We will briefly examine a few examples of disclosed vulnerabilities and breaches of systems that were made possible by inadequ

Trust the certificate at the OS level

Ubuntu

cp certs/domain.crt /usr/local/share/ca-certificates/myregistrydomain.com.crt
update-ca-certificates

How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

SSH keypair setup for GitHub (or GitHub/GitLab/BitBucket, etc, etc)

Create a repo.

Make sure there is at least one file in it (even just the README.md)

Generate a SSH key pair (private/public):

ssh-keygen -t rsa -C "[email protected]"

Generate a private key and a CSR(Certificate Signing Request )
Generate a CSR from an Existing Private Key
Generate a CSR from an Existing Certificate and Private Key
Generating SSL Certificates

View Certificate Entries

Open a webpage that uses the CA with Firefox
Click the lock-icon in the addressbar -> show information -> show certificate
the certificate viewer will open
click details and choose the certificate of the certificate-chain, you want to import to CentOS
click "Export..." and save it as .crt file
Copy the .crt file to /etc/pki/ca-trust/source/anchors on your CentOS machine
run update-ca-trust extract
test it with wget https://thewebsite.org
