Why Web Application Security Web Application Security is the most overlooked aspects of the company’s current software. Theft is on the rise by as much as 75% of cyber attacks are done by using the Internet and use Web-based applications.
Most companies have provided their data at the network level, but missed a crucial step in testing their web applications are vulnerable to attack.
The web application used to create certain security issues. 1. For delivery of services (design plans) for clients, Web applications should be available online 24x7x365 and 2. This means that they are always accessible and can not distinguish between legitimate users and hackers 3. For proper operation of the Web application should have direct access to the database server that contains sensitive information. 4. Most Web applications on your order and rarely pass through stringent quality control check the application ready to use 5. Through ignorance of the nature of hacking, organizations view the Web application layer as part of the network level, when it comes to security issues.
Infrastructure Security Organization convenient to think of infrastructure as an organization with different layers. In the same way you would be protected from rust by using various chemicals and antioxidants in the layers of paint, the system administrator puts into place a number of specific security solutions for each deal with specific areas of concern.
Level of security is an integral worldview is seen as a security hardening steps to minimize risk and maximize the intrusion protection around the key asset of any organization, data.
Layers of standard safety features include:
- Layer that contains the user’s software, including personal firewall, anti-rootkit, clean registry, backup, anti-virus, anti-phishing and anti-spy/adware.
- Transport layer, including SSL encryption, HTTPS, and the same protocol
- The level of access with access control, authentication, crypography, firewall, VPN, firewall, web application
- Network level with firewalls, network scanners, VPN and intrusion detection.
While network security scanner, Safety Analysis of assets on the network for possible vulnerabilities, Web vulnerability scanner (WVS), scan and analyze web-based applications (such as shopping carts, forms, login pages, dynamic content) for each gap due to improper coding that can manipulated by hackers.
For example, it is possible to trick the shape Login to believe that you have administrator rights by introducing a specially crafted SQL (a language understood by the database) command. This is only possible if the input (eg, user name and / or password field) due to sufficient processing (ie, made invulnerable) and sent directly to the SQL-query to the database. This is SQL Injection?
Network security defense provides no protection against such attacks, Web applications, such attacks are launched on port 80 (default for Web sites), which must remain open for business interruption.
Black box testing black box testing methodology to test only design .. In black box testing of web applications, web application itself is considered as a whole, without analyzing the internal logic and structure. Typically, scanners, web applications, whether web-based application can generally be manipulated to gain access to the database. Modern technology allows a greater degree of automation, in fact, reduce the manual input required for testing web applications.
It is important to say, reduction, and not to minimize or do away with. As well as security consultants will tell you, the automation will never replace the intelligence and creativity of human intervention.
In general, the first automatic scanner crawl the entire site, in-depth analysis of each file, they will find and display the entire website structure. After the discovery phase, the scanner automatically checks for vulnerabilities by launching a series of hacker attacks, basically mimics hackers. Scanner will review each page to the place where data can be entered, and then will try all the different combinations of inputs. Scanner will check vulnerabilities on web servers (to open), all Web applications and content of the web site itself. More reliable launch attacks using a variety of products such as smart heuristics level.
Heuristic Scanning the Web is important to understand that a web vulnerability scan should not be limited to specific scanning applications (such as ready mix truck) and / or vulnerability module (for example, from SQL injection, in phpBB Login Form) to the pre-defined library of known issues. If you wish to do so, your application will remain untested for their vulnerability. This is the main weakness of the products is based on matching vulnerability signatures.
Consider the anti-virus software as an example. Standard anti-virus software to scan thousands of known viruses, including viruses and is known for a long time (even those made for Windows 95 systems older). In this day and age it is rarely encounter this OS, but in the minds of consumers, most importantly, “how much virus software detect it?”. In fact, with the latest AV will provide protection for all but the virus works in the wild And this is the virus that causes the greatest damage .. Standard AV products without the right technology will not detect the virus in the wild if they can meet only “known” viruses. Good antivirus technology enables heuristic scanning of files or intellectual trying to find a way to model the behavior of applications that can cause the virus.
Web vulnerability scanning works very similar. It would be useful to detect known vulnerabilities known to the application only. Most of the heuristics involved in the detection of vulnerabilities hackers are very creative and begin their assault on custom web applications to create maximum effect.
Of course, this approach does not give false positives, but there is confusion and chaos. False positives occur due to an automatic scan flag problems that may seem vulnerable. Automation invaluable help and scanning accuracy depends on (a) how well your site is crawled to establish its structure and various components and connections, and (b) the ability to use the scanner wise variety of methods and techniques hackers against Web applications.
Automatic verification will lead to false positives. Of course, this level of technological complexity does not lead to zero false positives. It’s impossible. Automatic scanning will always result in false positives, depending on the products you use.
We always recommend automated scans must be coupled with a manual scan – this may be one point that all security experts emphasize. Unfortunately, companies do not realize the importance of manual input. If you want your web application will secure you need to spend considerable time examining the automatic side of things. This does not mean that automation is inaccurate – instead, it is very accurate and reduces a lot of work. Automatic scanning will help you to flag potential problems, including false positives and manual further investigation quickly.
Source Code Analysis A set of products related to web vulnerability scanning source code analysis, but they work differently for web crawlers vulnerability. Source code analysis of white-box testing tool that helps developers in their work, automatically analyzing the internal structure and logic of the source code itself for errors and security loopholes. The degree of complexity of these products is based on the specific application logic and a different coding languages. This means that there are some stable product on the market, while technology is moving very fast.Tags: integral worldview, intrusion protection, quality control check, stringent quality control, web application security
