Featuring a three-step scanning process, ScanDo is constructed to emulate a hacker's bag of tricks to determine a Web application's potential exposed holes, said Tal Gilat, CEO of New York-based Kavado.<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>Meanwhile, Okena announced StormSystem on Tuesday, its integrated series of products that provide intrusion prevention for applications without relying on signature-based techniques. StormSystem offers enterprises an underlying security infrastructure tied together by a common agent, said Dave Hammond, director of marketing communications for Waltham, Massachusetts-based Okena.<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>Following a series of high-profile break-ins of its applications and operating systems during the last six months, Microsoft has sworn to dedicate a greater effort to incorporate stronger security features into its products. Until results of that pledge come to pass, users must depend on security vendors to provide protection without affecting application performance, said Michael Rasmussen, senior industry analyst at Cambridge, Massachusetts-based Giga Information Group.<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br><img style="float:left;margin:10px;border:none;" src="" width="389" /><br><br>"[Application defense] is a big deal.

Hammond said Okena has plans to release StormTrack, which will identify and seal-off vulnerable components of an IT infrastructure, later in 2002.<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>Kavado's ScanDo vulnerability scanning product first examines every component a Web application is running, such as cookies and passwords, and records its makeup and contents. Secondly, it probes the application to uncover possible susceptibility to random security breaches or targeted attacks. A user can configure ScanDo to create and mimic an attack through Visual Basic scripts to compare results, Gilat said. Finally, ScanDo offers standard or customized graphical and textual reports on its complete findings.<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>ScanDo, which can be updated to incorporate the newest security tools from Kavado, is complementary to Kavado's InterDo product. InterDo deflects attacks against Web applications, said Gilat.<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>&#13;<br><br>ScanDo runs on Windows NT and 2000, with a Solaris version planned for the second quarter of 2002.

Web Applications: What are They? What of Them? - 22 Aug 2016 02:56


[[html]]Web Applications or Website Widgets<br><br>Over the past decade or so, the web has been embraced by millions of businesses as an inexpensive channel to communicate and exchange information with prospects and transactions with customers.<br><br>In particular, the web provides a way for marketers to get to know the people visiting their sites and start communicating with them. One way of doing this is asking web visitors to subscribe to newsletters, to submit an application form when requesting information on products or provide details to customize their browsing experience when next visiting a particular website.<br><br>The web is also an excellent sales channel for a myriad of organizations, large or small: with over 1 billion Internet users today (source: Computer Industry Almanac, 2006), US e-commerce spending accounted for $102.1 billion in 2006 (Source: comScore Networks, 2007).<br><br>All this data must be somehow captured, stored, processed and transmitted to be used immediately or at a later date. Web applications, in the form of submit fields, enquiry and login forms, shopping carts, and content management systems, are those website widgets that allow this to happen.<br><br>They are, therefore, fundamental to businesses for leveraging their online presence thus creating long-lasting and profitable relationships with prospects and customers.<br><br>No wonder web applications have become such a ubiquitous phenomenon. However, due to their highly technical and complex nature, web applications are a widely unknown and a grossly misunderstood fixture in our everyday cyber-life.<br><br>Web applications defined<br><br>From a technical view-point, the web is a highly programmable environment that allows mass customization through the immediate deployment of a large and diverse range of applications, to millions of global users. Two important components of a modern website are flexible web browsers and web applications; both available to all and sundry at no expense.<br><br>Web browsers are software applications that allow users to retrieve data and interact with content located on web pages within a website.<br><br>Today's websites are a far cry from the static text and graphics showcases of the early and mid-nineties: modern web pages allow personalized dynamic content to be pulled down by users according to individual preferences and settings. Furthermore, web pages may also run client-side scripts that "change" the Internet browser into an interface for such applications as web mail and interactive mapping software (e.g., Yahoo Mail and Google Maps).<br><br>Most importantly, modern web sites allow the capture, processing, storage and transmission of sensitive customer data (e.g., personal details, credit card numbers, social security information, etc.) for immediate and recurrent use. And, this is done through web applications. Such features as webmail, login pages, support and product request forms, shopping carts and content management systems, shape modern websites and provide businesses with the means necessary to communicate with prospects and customers. These are all common examples of web applications.<br><br>Web applications are, therefore, computer programs allowing website visitors to submit and retrieve data to/from a database over the Internet using their preferred web browser. The data is then presented to the user within their browser as information is generated dynamically (in a specific format, e.g. in HTML using CSS) by the web application through a web server.<br><br>For the more technically oriented, Web applications query the content server (essentially a content repository database) and dynamically generate web documents to serve to the client (people surfing the website). The documents are generated in a standard format to allow support by all browsers (e.g., HTML or XHTML). JavaScript is one form of client side script that permits dynamic elements on each page (e.g., an image changes once the user hovers over it with a mouse). The web browser is key - it interprets and runs all scripts etc. while displaying the requested pages and content. Wikipedia brilliantly terms the web browser as the "universal client for any web application".<br><br><img style="float:right;margin:10px;border:none;" src="" width="363" /><br><br>Another significant advantage of building and maintaining web applications is that they perform their function irrespective of the operating system and browsers running client side. Web applications are quickly deployed anywhere at no cost and without any installation requirements (almost) at the user's end.<br><br>As the number of businesses embracing the benefits of doing business over the web increases, so will the use of web applications and other related technologies continue to grow. Moreover, since the increasing adoption of intranets and extranets, web applications become greatly entrenched in any organization's communication infrastructures, further broadening their scope and possibility of technological complexity and prowess.<br><br>Web applications may either be purchased off-the-shelf or created in-house.<br><br>How do web applications work?<br><br>The figure below details the three-layered web application model. The first layer is normally a web browser or the user interface; the second layer is the dynamic content generation technology tool such as Java servlets (JSP) or Active Server Pages (ASP), and the third layer is the database containing content (e.g., news) and customer data (e.g., usernames and passwords, social security numbers and credit card details).<br><br><img class="aligncenter size-full wp-image-1350" title="Web Apps" src="" alt="What is a Web App?" width="576" height="302"/><br><br>The figure below shows how the initial request is triggered by the user through the browser over the Internet to the web application server. The web application accesses the databases servers to perform the requested task updating and retrieving the information lying within the database. The web application then presents the information to the user through the browser.<br><br><img class="aligncenter size-full wp-image-1351" title="How Web Apps Access Databases" src="" alt="How Web Apps Access Database Servers" width="576" height="456"/><br><br>Despite their advantages, web applications do raise a number of security concerns stemming from improper coding. Serious weaknesses or vulnerabilities, allow hackers to gain direct and public access to databases in order to churn sensitive data. Many of these databases contain valuable information (e.g., personal and financial details) making them a frequent target of hackers. Although such acts of vandalism as defacing corporate websites are still commonplace, nowadays, hackers prefer gaining access to the sensitive data residing on the database server because of the immense pay-offs in selling the data.<br><br>In the framework described above, it is easy to see how a hacker can quickly access the data residing on the database through a dose of creativity and, with luck, negligence or human error, leading to vulnerabilities in the web applications.<br><br>As stated, websites depend on databases to deliver the required information to visitors. If web applications are not secure, i.e., vulnerable to, at least one of the various forms of hacking techniques, then your entire database of sensitive information is at serious risk.<br><br>Some hackers, for example, may maliciously inject code within vulnerable web applications to trick users and redirect them towards phishing sites. This technique is called Cross-Site Scripting and may be used even though the web servers and database engine contain no vulnerability themselves.<br><br>Recent research shows that 75% of cyber attacks are done at web application level.<br><br><img class="aligncenter size-full wp-image-1352" title="Hackers and Web Applications" src="" alt="How Hackers Attack Web Applications" width="576" height="456"/><br><br>Websites and related web applications must be available 24 hours a day, 7 days a week, to provide the required service to customers, employees, suppliers and other stakeholders.<br><br>Firewalls and SSL provide no protection against web application hacking, simply because access to the website has to be made public - All modern database systems (e.g. Microsoft SQL Server, Oracle and MySQL) may be accessed through specific ports (e.g., port 80 and 443) and anyone can attempt direct connections to the databases effectively bypassing the security mechanisms used by the operating system. These ports remain open to allow communication with legitimate traffic and therefore constitute a major vulnerability.<br><br>Web applications often have direct access to backend data such as customer databases and, hence, control valuable data and are much more difficult to secure. Those that do not have access will have some form of script that allows data capture and transmission. If a hacker becomes aware of weaknesses in such a script, he may easily reroute unwitting traffic to another location and illegitimately hive off personal details.<br><br>Most web applications are custom-made and, therefore, involve a lesser degree of testing than off-the-shelf software. Consequently, custom applications are more susceptible to attack<br><br>Web applications, therefore, are a gateway to databases especially custom applications which are not developed with security best practices and which do not undergo regular security audits. In general, you need to answer the question: "Which parts of a website we thought are secure are open to hack attacks?" and "what data can we throw at an application to cause it to perform something it shouldn't do?".<br><br>This is the work of a web vulnerability scanner.<br><br>Acunetix Web Vulnerability Scanner<br><br>Proof of such exploits are readily available on the Internet and are the subject of discussion in several press releases by Acunetix, a leading vendor of web application security products. Click here to learn more about Acunetix Web Vulnerability Scanner.<br><br>Scanning for XSS vulnerabilities with Acunetix WVS Free Trial<br><br>To check whether your website has cross site scripting vulnerabilities, download the 14-day Trial of Acunetix WVS.

Web Application Security Risks You Should Know About - 05 Aug 2016 18:18


[[html]]Now that majority of the internet citizens have dealt with the nasty Heartbleed bug, it's time to take a look at some of the most common security risks that we can experience within our web applications, and perhaps it's time we look into those risks at a much deeper level.<br><br>At the end of the day, our customers and employers expect only the best from us; and security issues are not something that you just put aside for later. This year, we saw a huge attack being made on the very popular retail store Target; see here for details - in this attack, 110 million user account details were exposed to hackers.<br><br>Last year, Adobe Systems Inc. got attacked by hackers, which lead to an exposure of 3 million user accounts; read the report here - and the year before that, LinkedIn experienced an attack that led to 6.5 million user accounts being exposed to the public.<br><br>I don't consider such activity as normal, and although for the average person it only means that he needs to change his password, for many business owners and other money related institutions - it means plenty of headache, sleepless nights, and a lot of security work to be done.<br><br>We need to make sure that we're securing our web applications the right way, it's important that developers are aware of the common security pitfalls, and do everything in their power to prevent a new product or an application to be easily exploited, vulnerable.<br><br><img alt="2014-04-17-OWASP.png" src="" width="570" height="201"/><br><br>The Open Web Application Security Project (OWASP) is an open-source web application security project. The OWASP community includes corporations, educational organizations, and individuals from around the world. This community works to create freely-available articles, methodologies, documentation, tools, and technologies. <br><br>The OWASP open-source community is hands-down, the absolute best resource for any developer or business owner to go-to whenever there is a need to look into new security issues, or find a way to patch old ones. OWASP offers a handful of solutions, some of which include:<br><br>Security tools and ethics&#13;<br><br><img src="" width="371" /><br><br>Security books on variety of topics&#13;<br><br>Security libraries and controls&#13;<br><br>State of the art research&#13;<br><br>Provides conferences all across the globe&#13;<br><br>Mailing list access for latest updates&#13;<br><br>Hackers, criminals, or whatever is the word we may choose to give people who exploit vulnerabilities, they've got access to a wide variety of ways of manipulating your infrastructure, more specifically - your web applications.<br><br>It's important to know that there isn't just one way of attacking a web application, but multiple ways that have their own scale of difficulty and threat level, some are less serious; while others need to be avoided at all costs.<br><br>A tiny mistake can go a very long way, and in the worst case scenario, it may even put an end to your company - which would be unfortunate, giving that we've got access to all this material on how to protect ourselves and our customers.<br><br>10 Web Application Security Risks<br><br>Last year, OWASP foundation published a list of the top 10 most serious web application security threats, and it's the most detailed review of these flaws that you will find anywhere else on the web. <br><br>You can find that list by following this link, make sure that you've got time on your hands - as there is plenty of research and new information to learn about.<br><br><img alt="2014-04-17-Top102013Top10OWASP.png" src="" width="570" height="184"/><br><br>It will all make more sense when you begin to investigate your own code, and start implementing the much needed precautions as provided by the OWASP foundation website. It's more serious that we think, and in the most recent news - a security company from Sweden, had gained read access to one of Google's production servers; a feat that many hackers dream about.<br><br>They were rewarded a $10,000 bounty, and plenty of media attention to last them for a lifetime.
