Cool design for ethical hackers :) | Perfect for T-shirts, hoodies, mugs, stickers etc!

The Open Web Application Security Project is an online community that produces freely-available articles, methodologies, documentation, tools, and technologies in the field of web application security.

For me, Dinosaurs reminds me of the time. The time they lived in and the time we are currently living in. There is a gap between those two, right? A TimeGap? Well, that's the theory!

The CAPTCHA is annoying for us as humans, but it could be a great way to stop automatic attacks or bots like brute force, CSRF or even XSS attacks.

OWASP is a foundation that provides trainings, guidelines and useful tools for cybersecurity professionals to make the internet a safe place. This is a black background with white letters design version.

The Open Systems Interconnection model is a conceptual model that characterises and standardises the communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology

The helmet.js should be the minimum security requirement for node.js express applications. By doing so, developers can provide protection to the web application with the necessary secure http headers.

A design about the the common weakness enumeration 89 represented in an iconic way. Good for secure coding guideline and awareness to avoid being vulnerable to sql injection attacks.

A design version with white letters and black background, This is a reminder for developers to replace any print used for debugging purposes with logger to write them in files.

Kind secure coding advice for developers to ensure that the content security policy header is used on http responses and mitigate XSS attacks on users visiting your website. This is a black background with white letters design version.

When dealing with multithreading applications, it is important to make a copy of the input mutable object before processing it to avoid race conditions.

The helmet.js should be the minimum security requirement for node.js express applications. By doing so, developers can provide protection to the web application with the necessary secure http headers. This is a dark background with white letters design version.

A design about the the common weakness enumeration 79 represented in an iconic way. Good for secure coding guideline and awareness to avoid being vulnerable to XSS attacks.

If the web application is not properly implemented and it doesn't performs input validation correctly on login, then it could be bypassed by sql injection.

The design is about one of the guidelines provided by OWASP, to put in place security measures to restrict the import or usage of packages with known vulnerabilities.

Any input that is controllable by the user is susceptible of being manipulated and turn it as an evil payload for remote code execution on the victim server. Black background design with white letters.

To mitigate the risk of supply chain attacks or other similar ones that implies malicious code being incorporated in the code, it is recommended to perform malware scanning to the dependencies before using them into your project.

APP Security Engineer is a Cool design of this role tittle. If you are this kind of cybersecurity professional, your duty is to reduce the risk as much as possible in code and dependencies. Also you'll enact activities like threat modelling, malware scanning, secure coding practices and correct secret management.

This should be the input validation steps that the code must do to avoid processing harmful untrusted data. This is a black background with white letters design version.

The best practice is to disable external entities on XML, otherwise, it will be the door for different type of attacks like the Billion Laughs. A cool black background version design with white letters.

A black background with white letters design version about one of the guidelines provided by OWASP, to put in place security measures to restrict the import or usage of packages with known vulnerabilities.

A cool design with a black background and white letters about one of the web application threats, the cross site scripting or XSS. This kind of attack abuses the weakness of the site to deliver malicious code on clients browsers to steal your cookies or other harmful actions.

This is one of the best practice which is a must when developing any web server that provides cookies. With the secure flag assigned on cookies, it will only be transferred through HTTPS. Black background with white letters design version.

Want to avoid the undesired clickjacking attack on your website? Then X-Frame-Options should be one of the headers to respond with sameorigin value. Or you can make it even more restrictive with deny. The result is avoiding any eventual attacker to use hidden frames to compromise the website user.

A cool and funny way to remind one of the OWASP guidelines, the A3:2021. This design will guide your developers to follow the best practices to avoid Injections on code no matter it is LDAP, XML, SQL, Command and so on.

Esto es un diseño recordatorio a los desarrolladores para que eviten mostrar por pantalla errores que puedan dar pistas de cómo funciona la aplicación o revelar más información de lo preciso. En cualquier caso, hay que escribirlos en ficheros de logs.

A shield design of the input validation steps that developers should do in the methods or functions that manipulates untrusted data. This is one of the best practice of OWASP for secure coding.

In case that x-powered-by header is delivered by your service, override it with misleading information to make attackers life harder like "Not Your Business 1.0"

A design about the the common weakness enumeration 20 also known as improper input validation. If user input is not properly escaped, sanitised and validated then the attackers can perform DoS, RCE or even tamper the information.

Fuzzing is an important testing to be done on running applications because it can catch flaws that static analysis can't like buffer overflows or memory corruption.

HTTPOnly flag for cookies should be a must. This avoids other unwanted usages of cookies from your browser like scripts and only restricts its usage for HTTP.

A funny design to concern developers that the usage of eval() to process or parse untrusted data could let attackers to inject code to run.

One of the best practices stated in OWASP is to allow only to use local static DTD when processing XML to avoid XXE attacks.

This should be the input validation steps that the code must do to avoid processing harmful untrusted data.

Want to avoid the undesired clickjacking attack on your website? Then X-Frame-Options should be one of the headers to respond with sameorigin value. Or you can make it even more restrictive with deny. The result is avoiding any eventual attacker to use hidden frames to compromise the website user. This is a black background with white letters design version.

To protect from file upload attacks on your website that could leave attackers to upload malicious software or backdoors, here's some of the protections to prevent such attacks.
