Test de pénétration d'application Web : qu'est-ce que c'est ?

Le test de pénétration d’application Web est une méthode pour vérifier la sécurité des applications Web. Découvrez comment cela fonctionne !

C’est également connu sous le nom de test de pénétration d’application web ou de test de sécurité, qui est une évaluation organisée de la sécurité d’une application web pour identifier l’exposition et la faiblesse qui pourraient être exploitées par des acteurs malveillants.

1. Identifying the target application and its environment. 

2. Gathering information about the target application. 

3. Identifying potential vulnerabilities. 

4. Exploiting the identified vulnerabilities. 

5. Documenting the results and providing recommendations. 

Le test d’intrusion des applications web, également connu sous le nom de test de sécurité ou de test d’intrusion, est une évaluation organisée de la sécurité d’une application web afin d’identifier les expositions et les faiblesses qui pourraient être exploitées par des acteurs malveillants. L’objectif principal du test d’intrusion est d’évaluer de manière proactive la posture de sécurité d’une application web et d’identifier les vulnérabilités potentielles avant que des attaquants ne puissent les exploiter.

Pendant un test d’intrusion d’application web, des professionnels de la sécurité qualifiés, connus sous le nom de testeurs d’intrusion ou de hackers éthiques, simulent divers scénarios d’attaque pour découvrir les failles de sécurité qui pourraient entraîner un accès non autorisé, des violations de données ou d’autres activités malveillantes. Le processus implique les points suivants :

1. Identification de l’application cible et de son environnement.

2. Recueil d’informations sur l’application cible.

3. Identification des vulnérabilités potentielles.

4. Exploitation des vulnérabilités identifiées.

5. Documentation des résultats et fourniture de recommandations.

Le test d’intrusion des applications web est un processus essentiel pour assurer la sécurité des logiciels et des systèmes informatiques. Les tests d’intrusion peuvent être effectués manuellement ou automatiquement à l’aide de logiciels spécialisés. Ces outils peuvent être utilisés pour rechercher des vulnérabilités connues et des failles de sécurité dans les applications web et les systèmes informatiques. Les tests d’intrusion peuvent également être effectués pour vérifier si les applications web respectent les normes et les réglementations en matière de sécurité.

Tester la sécurité des objets connectés

Tester la sécurité des objets connectés est essentiel pour protéger nos données et notre vie privée. Découvrez comment vous assurer que vos appareils sont en sécurité.

## La sécurité de l’Internet des objets (IoT) est essentielle

L’Internet des objets (IoT) a révolutionné nos vies et apporté de nombreux avantages, mais il présente une grande surface d’attaque et n’est pas sûr tant qu’il n’est pas sécurisé. Les appareils IoT sont une cible facile pour les cybercriminels et les pirates informatiques s’ils ne sont pas correctement sécurisés. Vous pouvez avoir de graves problèmes avec des données financières et confidentielles qui sont invitées, volées ou cryptées.

Il est difficile de repérer et de discuter des risques pour les organisations, sans parler de la construction d’une méthodologie globale pour y faire face, sans connaissances pratiques de ce qu’est la sécurité IoT et sans la tester. La prise de conscience des menaces de sécurité et la façon d’y échapper est la première étape, car les solutions IoT nécessitent beaucoup plus de tests qu’auparavant. La sécurité intégrée est souvent absente lorsqu’il s’agit d’introduire de nouvelles fonctionnalités et produits sur le marché.

En tant que scientifique informatique enthousiaste, je sais que le test est une partie essentielle du processus de développement de produits IoT. Les tests peuvent être effectués à chaque étape du cycle de développement, depuis le développement jusqu’à la mise en production. Les tests peuvent être effectués manuellement ou automatiquement, selon les besoins spécifiques et les contraintes budgétaires. Les tests peuvent inclure des tests fonctionnels, des tests de performance, des tests de sécurité et des tests de conformité. Les tests peuvent être effectués sur des appareils physiques ou virtuels, en fonction des exigences et des contraintes. Les tests peuvent également être effectués à l’aide d’outils spécialisés tels que des outils de test d’intrusion, des outils de test d’authentification et des outils de test de sécurité.

Les tests peuvent aider à identifier les vulnérabilités et à déterminer si les produits IoT sont conformes aux normes de sécurité et aux exigences réglementaires. Les tests peuvent également aider à améliorer l’efficacité et la fiabilité des produits IoT et à réduire les risques liés à la sécurité. Les tests peuvent également aider à améliorer la qualité du produit et à réduire le temps et les coûts de développement. Les tests peuvent également aider à améliorer l’expérience utilisateur et à assurer un meilleur niveau de sécurité pour les utilisateurs finaux.

En conclusion, le test est essentiel pour assurer la sécurité des produits IoT. Les tests peuvent être effectués à chaque étape du cycle de développement et peuvent aider à identifier les vulnérabilités, à améliorer l’efficacité et la fiabilité des produits IoT, à réduire les risques liés à la sécurité et à améliorer l’expérience utilisateur.

About This Series

Last time, we covered a scenario in which a threat actor found leaked RSA private keys used by a TLS wildcard certificate for “Poor Corp.” By chaining the leaked private key with DNS misconfigurations, the attacker was able to impersonate a Poor Corp subdomain and use it to create highly effective phishing emails.

In this series, we will dissect not just what an attacker can do to get access to credentials, but also what they would do after getting that initial access. We will walk through a different threat scenario in each part of the series and tell stories of malicious hackers that are either true, based on a true incident, or reasonably theoretical.

In the early days of the internet, security was little but an afterthought. Then as hackers started to exploit businesses’ lax security postures, things gradually started to change. At first, nonprofits like the Electronic Frontier Foundation started pushing web users to embrace HTTPS Everywhere. In response, certification authorities began offering free SSL certificate variations to any site admin that wanted one. As a result, at least 79.6% of all active websites now use SSL.

That was only the beginning. In the ensuing years, developers and web application administrators gradually started to harden their apps against all manner of attacks. They rolled out more complex password requirements. They started to add two-factor authentication as a default measure. They even started putting public-facing services behind high-performance web application firewalls.

WordPress 6.0 has been released, and another niche jazz musician will be enjoying extra Spotify royalties next month.

WordPress 6, named for latin-jazz musician Arturo O’Farrill, is the realization of a change of direction the WordPress Foundation adopted several years ago.

All versions of WordPress now power around 42% of the web. That’s approximately 810,000,000 sites. If you looked at each site for a single second, without pausing to blink, it would take you over 25 years to see the home page of each one — of course, if you factor in how long a typical WordPress site takes to load it would take well over a century.

Some people (i.e., me) have been predicting the decline of WordPress for so long that sooner or later, we were bound to be correct. And, despite its astonishing reach, there are some signs that its market share may now be in decline. Even the W3C abandoned it in favor of Craft.

Of the 1,930,000,000 sites that currently make up the web, only around 400,000,000 are active. WordPress’s long-term dominance, coupled with a stalling market share, means that a disproportionate number of abandoned sites are WordPress. With site builders like Wix, Squarespace, and Shopify taking huge chunks of WordPress’ share of new sites, WordPress is facing something of a cliff edge.

What the ill-informed naysayers (i.e., me) hadn’t counted on was that WordPress had already seen the writing on the wall and formulated a plan…

WordPress’s problem has always been its legacy code; supporting out-of-date ideas and a spaghetti-like codebase has meant a great deal of work to do anything new. As a result, the last few releases have seen great ideas stifled by labored implementation. Even the most loyal WordPress user has to admit that Gutenberg, while filled with potential, doesn’t work the way it should. However, with WordPress 6, all the work may be starting to pay off.

With version 6, the block editor in WordPress is starting to feel like a design tool that, if not perfect, is at least usable. Editing content no longer feels like you’re fighting against the UI. Most importantly, the bar for creating a site is much, much lower. WordPress 6 also offers improved performance and accessibility, both areas that have traditionally been lacking. Security is still something of an issue, but that is mainly due to the ROI for hackers that massive market shares generate.

WordPress, it seems, has arrived at two conclusions: its main competition isn’t other CMS but other site builders. To maintain its market dominance, it needs to cater not to professionals but to amateurs.

Don’t get me wrong; the WordPress ecosystem will benefit from WordPress 6, at least reputationally. New sites run by amateurs eventually become established sites run by, if not professionals, then at least knowledgeable amateurs.

OK, so WordPress probably isn’t a good choice for enterprise sites. And there are certainly better options for ecommerce. And as for SEO, well, probably best not mentioned.

But in WordPress 6, we have a free, open-source site builder that lowers the bar for making a new site. It’s a credit to the community that has persevered to produce it.

Chatbots Are Here To Stay

Chatbots have been around for a long time and based on the global chatbot market size (and the expected growth), they will stick around for a long time and gain importance. In the past, they’ve rarely met customer expectations or provided much positive experience. However, over the last few years, advances in conversational AI have transformed how they can be used. Since chatbots offer a wide range of applications, in certain cases, they become responsible for collecting and protecting personal information as well. 
Consequently, they are a great attraction for hackers and malicious attacks too. The responsibility of ensuring chatbot security has become more evident after the introduction of GDPR in Europe. As statistics show that this technology will be a determining factor in our lives, security testing must also become part of our daily tasks, so that these chatbots can be used with confidence.

Security Risks, Threats, and Vulnerabilities                 

The words risk, threat, and vulnerability are often confused or used interchangeably when reading about computer security, so let’s first clarify the terminology:

  • Vulnerability refers to a weakness in your software (or hardware, or in your processes, or anything related). In other words, it’s a way hackers could find their way into and exploit your systems.
  • A threat exploits a vulnerability and can cause loss, damage, or destruction of an asset – threats exploit vulnerabilities.                
  • Risk refers to the potential for lost, damaged, or destroyed assets – threats + vulnerability = risk! 
The well-known OWASP Top 10 is a list of top security risks for a web application. Most chatbots out there are available over a public web frontend, and as such, all the OWASP security risks apply to those chatbots as well. Out of these risks, there are two especially important to defend against, as in contrast to the other risks, those two are nearly always a serious threat — XSS (Cross-Site Scripting) and SQL Injection.
In addition, for artificial intelligence-enabled chatbots, there is an increased risk for Denial of Service attacks, due to the higher amount of computing resources involved.

Vulnerability 1: XSS – Cross-Site Scripting

A typical implementation of a chatbot user interface:           

           

  • There is a chat window with an input box.
  • Everything the user enters in the input box is mirrored in the chat window.
  • Chatbot response is shown in the chat window.

The XSS vulnerability is in the second step — when entering text including malicious Javascript code, the XSS attack is fulfilled when the web browser is running the injected code:

 <script>alert(document.cookie)</script>              

Possible Attack Vector

For exploiting an XSS vulnerability the attacker has to trick the victim to send malicious input text. It can be done through one of the following ways:

Every digital aspect comes with a security risk if not handled properly. With billions of people using online and digital technologies worldwide, there are ample opportunities for hackers to break the security wall and create unrest all around. Cybersecurity news has become too frequent these days. We see bitcoin mining, credit card credential stealing, injecting malicious code into the systems, stealing confidential data, etc. In today’s digital world, it is not just about having speed, reaching your customers quickly, easy setup, mind-blowing features, etc., but rather, it is about how safe or secure your systems, data, or features are.

What is Cybersecurity?

The approach and practice of securing electronic data, networks, computer systems, and any form of digital infrastructure from malicious attacks is known as Cybersecurity. Banks, educational institutions, tech companies, government agencies, publishing media houses, hospitals, and every sector invest in cybersecurity infrastructure to protect their customer data, secrets, and business intelligence from attackers.

Data privacy and protection are two imperative aspects for all businesses today as they could be prone to security breaches. Many small and medium organizations tend to ignore application security as they believe only large enterprises are targeted by hackers. However, statistics tell a different story, 43% of cybercrimes happen against small businesses.

There are several reasons behind a cyber-attack against these organizations; from old, unpatched security vulnerabilities to malware or human errors which make take them a lucrative target for attackers. So, ignoring Cyber Security can bring you on the radar of hackers even if you are a startup.
