  Penetration Tester Overview A penetration tester is a network security expert who attempts to break into or discover potential exploits in various computer systems and software.They can be thought of as a form of ethical hacker.They are typically expected to conduct a number of tests, most of which are focused on network penetration, and then write up evaluation reports based on their findings. While they will frequently conduct pre-determined sorts of tests, they will also develop their own tests for a significant amount of the time, which demands creativity and inventiveness, as well as a high level of technical understanding and know-how.    You'd be expected to conduct formal tests on web-based apps, networks, and other sorts of computer systems on a regular basis as a penetration tester.Physical security inspections of servers, computer systems, and networks will also be expected of you.You'll be conducting regular security audits from both a logical/theoretical an...

HOW TO IMPROVE WEB APPLICATION SECURITY      Robust security measures must advance in tandem with web application technologies. Web app security threats are real and happening all over the world. To protect against emerging threats, standard measures are no longer sufficient. Fortunately, apps do not have to remain vulnerable, waiting for bad actors to abuse them. To safeguard this ever-increasing attack surface, robust security procedures and practices can be implemented. How to Improve Web Application Security  Choose a secure host Secure your login pages using SSL (HTTPS) encryption  Always sanitize and validate user input Have a good password policy  Limit access rights and credentials Keep your website clean Ensure everything is up to date Keep regular backups Make sure to tweak the default settings of your CMS Run security tests on your website for vulnerabilities             Sometimes the most straightforward approa...

 WEB APPLICATION FIREWALLS (WAF) What is WAF ?      Web application firewalls assist load balancing by examining HTTP traffic before it reaches the application server. They also protect against web application vulnerability and unauthorized transfer of data from the web server at a time when security breaches are on the rise. According the the Verizon Data Breach Investigations Report, web application attacks were the most prevalent breaches in 2017 and 2018.    How do web application firewalls work ?     Web application firewalls (WAFs) are designed to be installed on the application layer and operate as a two-way gatekeeper, analyzing HTTP/HTTPS traffic entering and exiting the application. If malicious activity is detected, the WAF will take action.WAFs have the advantage of operating independently of the application while still being able to adapt to changes in the application's behavior.As a result, adding a new feature to the app w...

THE TOP 05 SECURITY VULNERABILITIES       Web application security is a central component of any web-based business. The global nature of the Internet exposes web properties to attack from different locations and various levels of scale and complexity. Web application security deals specifically with the security surrounding websites, web applications and web services such as APIs.  SQL INJECTION What is SQL INJECTION ?      SQL Injection is a technique for poisoning dynamic SQL statements by commenting out sections of the statement or attaching a condition that will always be true. It exploits SQL statements to execute malicious SQL code by exploiting design weaknesses in poorly constructed online applications.     CROSS SITE SCRIPTING (XSS) What is CROSS SITE SCRIPTING ?     Cross-site scripting (XSS) is a vulnerability in which an attacker embeds code on a legitimate website that executes when the victim vis...

WEB APPLICATION  What is WEB APPLICATION ? In today’s world, the usage of web applications growing day by day. The professionals of software area like Software Developer and Software Testers need to have familiar with Web Applications. It is a client-server application program, stored on a remote server that uses web browsers and web technology to perform specific function over the Internet through a browser interface. As said above, It is a client-server application program, therefore in the client-server environment, multiple computers can share information like saving the information into a database. The “client” can be used to enter the information, and the ‘server’ is used as storage for the information.   How do web applications work? A typical web application workflow looks like the following:   A user submits a request to a web server over the internet, either through a web browser or through an app's user interface. The webserver send...

WHAT IS WEBSITE       A website is a collection of web pages, photos, and other items linked together to create a bigger, structured document.Consider a website to be a book, with each page representing a web page.  A website can be as simple as a single page or as complex as thousands.Text, photos, and other features will be unique to each page.All web pages and elements are then saved on your web host server in a folder.  Each web page is written in codes, which specify the page's layout, format, and content. HTML is the most widely used coding language for creating web pages.     How do websites work? It's critical to understand how websites work before you start building your own and launching it on the Internet.      Here are some basic terms:  A website is nothing more than a collection of web pages with codes describing the layout, format, and content of each page. The web server is an internet-connected computer...

WEB APPLICATION SECURITY     Web application security (often referred to as Web AppSec) is the concept of designing websites to function normally even when they are attacked. The notion is integrating a set of security measures into a Web application to protect its assets from hostile agents.      Web applications, like all software, are prone to flaws. Some of these flaws are actual vulnerabilities that can be exploited, posing a risk to businesses.Such flaws are guarded against via web application security.      It entails employing secure development approaches and putting in place security controls throughout the software development life cycle (SDLC), ensuring that design flaws and implementation issues are addressed. Why is web security testing important?   The goal of web security testing is to identify security flaws in Web applications and their setup.  The application layer is the primary target (i.e., what is ru...
