Web application firewalls play an important role in the security of websites as they can mitigate risks and they can offer protection against a large-scale of vulnerabilities.That is the reason that many companies in nowadays are implementing a web application firewall solution in their existing infrastructure.Of course an implementation of a WAF on its own cannot resolve the security problems that a web application might have and proper modifications must be made in order many of the attacks to be able to identified and blocked.

Penetration testers must be aware before they start the web application engagement if there is a WAF in place as the results of their attacks can be affected.So if the penetration test is a white-box then this question should be asked in the initial meetings with the client.If it is a black-box then the penetration tester should try to investigate on his own whether or not there is a web application firewall in place.In this article we will try to examine the methods and the tools that will allow us to detect a WAF.

What is Penetration Testing?

Penetration testing is a type of security testing that is used to test the insecurity of an application. It is conducted to find the security risk which might be present in the system. If a system is not secured, then any attacker can disrupt or take authorized access to that system. Security risk is normally an accidental error that occurs while developing and implementing the software. For example, configuration errors, design errors, and software bugs, etc.

 

Why is Penetration Testing Required?


Penetration testing normally evaluates a system’s ability to protect its networks, applications, endpoints and users from external or internal threats. It also attempts to protect the security controls and ensures only authorized access.

Penetration testing is essential because −

Python is one of the most famous programming languages in the world and it was the second most used language in GitHub projects in 2017. So if you’re interested in Python and in web development, you’ve most probably heard of Django. The rising fame of web frameworks nowadays makes it quite confusing to learn a new framework and choose which one you want to work with.

Today, we take an extensive look at Django to be able to wrap our heads around this amazing technology.

What is Django?

Django is an MVT web framework used to build web applications. It defines itself as a “batteries included” web framework, with robustness and simplicity to help web developers write clean, efficient and powerful code. It is among the most famous web frameworks out there in the world and it’s one of the most used frameworks as well. It’s used by Instagram, Youtube, Google and even NASA for their website. So let’s break it down even further to learn more about it.

Understanding the password-cracking techniques hackers use to blow your online accounts wide open is a great way to ensure it never happens to you.

You certainly will always need to change your password, and sometimes more urgently than you think, but mitigating against theft is a great way to stay on top of your account security. You can always head to www.haveibeenpwned.com to check if you're at risk but simply thinking your password is secure enough to not be hacked into, is a bad mindset to have.

So, to help you understand just how hackers get your passwords – secure or otherwise – we've put together a list of the top ten password-cracking techniques used by hackers. Some of the below methods are certainly outdated, but that doesn't mean they aren't still being used. Read carefully and learn what to mitigate against.

More and more developers are considering blockchain for apps, as this technology—originally developed for Bitcoin cryptocurrency—holds tremendous potential for applications that require data storage or ledger-type functionalities. In fact, blockchain can benefit virtually any app that must stow and access large volumes of data in a secure, reliable manner. But what are the precise advantages of using blockchain technology for mobile apps? Well, the benefits range from security and reliability to decreased development and maintenance costs.

Benefit #1: Blockchain is Secure
The security that’s used in blockchain technology is simply the best, as it leverages some of the most advanced cryptography in existence. In fact, it’s a form of technology that is secure by design, meaning it was built in a way that allows for the highest level of security and encryption (while the Bitcoin blockchain data is not encrypted by default, this technology can easily accommodate encryption, if desired).

 

So, you want to start a new project from scratch, and you’re looking for the best web development platform. When it comes to web programming languages, it’s not that easy to make a choice which complies with your requirements.

In the following article, we're going to compare Ruby vs. PHP in 2018 and find the main pros and cons of critical aspects of both technologies. The latest versions of languages are Ruby 2.5 and PHP 7.2. All statistics shown below is relevant for June 2018.

Both languages are more than 20 years old, mature and proven in production. A lot of great products were created on their basis. So let’s look at these technologies from the beginning.

Social engineering penetration testing is the practice of attempting typical social engineering scams on a company’s employees to ascertain the organization's level of vulnerability to that type of exploit.

Social engineering pen testing is designed to test employees' adherence to the security policies and practices defined by management. Testing should provide a company with information about how easily an intruder could convince employees to break security rules or divulge or provide access to sensitive information. The company should also get a better understanding of how successful their security training is and how the organization stacks up, security-wise, in comparison to their peers.

Social engineering testing may be conducted as part of more comprehensive penetration tests (pen tests). Like ethical hacking methods, the tests themselves generally replicate the types of efforts that real-world intruders use.

IBM buying Red Hat should be great for Open Source, good for IBM and healthy for the cloud wars.

It was just announced that IBM bought Red Hat for $34 billion in cash. Wow!

I remember taking the bus to the local bookstore to buy the Red Hat Linux 5.2 CD-ROMs. It must have been 1998. Ten years later, Red Hat acted as an inspiration for starting my own Open Source business.

While it's a bit sad to see the largest, independent Open Source company get acquired, it's also great news for Open Source. IBM has been a strong proponent and contributor to Open Source, and its acquisition of Red Hat should help accelerate Open Source even more. IBM has the ability to introduce Open Source to more organizations in a way that Red Hat never could.

Introduction

Virtualization packages are means for users to run various operating systems without "bare-metal" hardware - basically, you can run more than one operating system on a single computer without dual-booting or similar approaches. Virtualization software emulates a real machine and "fools" the guest operating system into thinking it's running on a real computer. Besides the more obvious advantages, virtual machines help create a greener and easier to administer computing environment. Looking at the trends in the IT industry, virtualization has seen quite a boom in the last few years, because it fits the concepts of utility computing and/or software as a service. Virtualization can be useful to you if you are an enterprise architect, developer, a home user or basically everything in between. We will begin with a short introduction about virtualization in general, then we will specifically treat VirtualBox and KVM as they seem to be most popular open source full virtualization solutions. You are expected to know your way around Linux systems, how to install a Linux distribution and how to install software on it, although we will show you how to install the two aforementioned virtualization packages on some of the popular Linux distributions.

Definition of Technology

What Is Technology? Technology is a body of knowledge devoted to creating tools, processing actions and the extracting of materials. The term ‘Technology” is wide, and everyone has their way of understanding its meaning. We use technology to accomplish various tasks in our daily lives, in brief; we can describe technology as products and processes used to simplify our daily lives. We use technology to extend our abilities, making people the most crucial part of any technological system.

Technology is also an application of science used to solve problems. But it is vital to know that technology and science are different subjects which work hand-in-hand to accomplish specific tasks or solve problems.
