Course Description

In Web Defense Fundamentals, Ken Underhill takes you through the different aspects of Web application Security. You will learn OWASP top 10 and the vulnerabilities that are found across the web applications. Detection and remediation for OWASP top 10 are covered. By learning this course, organizations and individuals can ensure that their web applications are safely deployed and secure against the prying eyes of hackers, ensuring that industrial standards of Open Web Application Security Project (OWASP) are met.

Businesses and organizations want to deploy their web applications safely for consumer use, while protecting against hackers simultaneously. Organizations will be more likely to employ developers who understand the industry standards of the Open Web Application Security Project (OWASP). Developers who earn OWASP certification will have a vast array of tools to protect an organization from online hackers.

Developers who take Web Application Security Training can provide a strong Web Defense to their personal content or a business or organization’s website that is consumer facing.

What Is Web Defense?

Web Defense protects a company or organization’s users when they are browsing the internet. Developers who practice good Web Defense learn how to approach the various vulnerabilities that can be found in web applications and employ strong protections within the application’s code.

Why Is Web Application Security Important?

Businesses need Web Application Security because protecting customer or user information is good business. Protecting customer information helps ensure consumer trust. Hackers target highly vulnerable organizations, so practicing good Web Application Security is essential.

If hackers perform a data breach on a company and steal customer information, once consumers find out, they will lose trust in the organization and likely won’t return for additional business. Lost trust results in a tainted reputation and even lost revenue for the targeted business or organization.

In 2018, any website without SSL (HTTPS) was marked “insecure.” Without the proper steps to secure a website, even new users or customers will feel hesitant to even browse the content because they’ve been warned the site may be insecure.

Hacker attacks are on the rise, with one happening every 39 seconds, according to [Security Magazine]( These frequent attacks result in about 50,000 hacked websites every day. Most of these sites are small businesses unintentionally sending malicious code for hackers.

However, the best defense is often the best offense. Having proper security in place helps discourage hackers. Attacks often fail, further demonstrating the need for proper protection. Sucuri, a cloud-based firewall provider, reported it tallied more than 170 million blocked attack attempts in 2019.

In the end, taking steps to protect your business or organization’s website before a breach costs less than trying to remedy the situation after a hack.

Why Web Application Security Training Is Important?

Web Application Security Testing evaluates if confidential data stays secure and users are able to only perform the tasks a website owner authorizes them to.

Security testing ahead of an attack provides assurance that confidential data will remain confidential if a hacker targets your website. When a developer tests their own website, it helps expose any holes in the system that could be vulnerable.

Some developers also run a “pen test,” short for penetration test, which is an authorized simulated cyberattack, which is performed to evaluate the system’s security. A pen test differs from a vulnerability test, which allows developers to identify, quantify, and prioritize their website’s vulnerabilities.

The best security systems regularly test to find vulnerabilities and then evolve their protections to protect hackers from gaining access to unauthorized information.

How Do You Learn Web Application Security?

Developers who want to learn web application security can do so through online programs such as Cybrary’s online web security training course. Intermediate level developers will find Cybrary’s course easiest to complete.

Cybrary’s Web Defense Fundamentals program offers students the opportunity to learn the essential skills necessary to deploy OWASP in the workforce. Cybrary’s program allows students to learn at their own pace by breaking down its content into smaller, more digestible modules that allow students to either learn the necessary skills quickly or if they need more time to have a natural stopping point in between learning essential skills.

Cybrary’s web application security training spans 1 hour and six minutes, making it easy to complete in one day if the student desires. The longest module is the course assessment, which lasts 15 minutes. After successfully completing the Web Application Security course, Cybrary provides a web application security certification to students.
