A WAF keeps a track of the HTTP traffic that comes to your website/web application. Basically, it monitors all the requests that are coming to your web application/website.
A study by Clark School suggests that there is a hacker attack every 39 seconds over the internet which affects one in three Americans every year. Due to the growth in popularity of the internet, there are a lot of criminal or unwanted activities going on over the internet. The HTTP protocol is simple and this leads to easier stealing and spoofing identity. With the increase in the number of businesses over the internet protecting online information has become very critical and this needs to be addressed.
According to many online resources the number one targeted server-side vulnerabilities are Web Applications such as content management system(CMS like WordPress, Drupal, Magneto, etc.), Wikis, Portals, discussion forums, banking systems and many more. This makes detecting and preventing these activities a critical task for every company.
No application code is a completely secure code. It is a normal thing to have bugs in your Web Application, even the best developers are prone to errors.
The OWASP provides a broad technical definition for a WAF as “a security solution on the web application level which - from a technical point of view - does not depend on the application itself.”
A WAF keeps a track of the HTTP traffic that comes to your website/web application. Basically, it monitors all the requests that are coming to your web application/website. If the WAF feels that the incoming requests are suspicious ie. if the incoming request can harm your website (eg. the request may contain some code that can make some changes to your database or an unauthorized person/hacker would be able to gain access to your web application) WAF blocks those requests and prevents your website from unwanted attacks. Basically WAF filters and blocks suspicious or unwanted HTTP traffic to and from a web application.
Hackers find vulnerabilities and application security flaws in the website and then they attack the website using techniques such as SQL injection, XSS(cross-site scripting ), file inclusion and security misconfigurations. Having a WAF will prevent such attacks from causing harm to your website.
WAF acts as a barrier between your website and the hacker by protecting your website from hacks, Cross-site scripting, SQL injections, DOS attacks, etc. This is all done on a continuous basis, giving you the best chance to protect your website before an attack is successful.
You would probably feel that hackers go after only big companies or websites and they wouldn’t be interested in your website, but this is a big misinterpretation. Most hackers do not try to steal social security numbers or credit card information of millions of people at a go. The majority of hacks occur for seemingly less malign purposes. For example, many hackers infiltrate your server in order to send out spam emails by the millions. They might inject unwanted code that will affect the performance and reliability of your website.
Some stats you might want to know, 43% of cyber attacks target small business, 64% of companies have experienced web-based attacks, 62% experienced phishing & social engineering attacks, 59% of companies experienced malicious code and botnets and 51% experienced denial of service attacks.
miniOrange WAF provides three types of solutions plugin, On-premise module and Cloud solution from which users can choose anyone which will suit best for their website.
It is simple and easy to set up a plugin to secure your website. You can directly install the plugin from the Wordpress marketplace and activate WAF. Any Request coming to WordPress is first captured by the miniOrange WAF and is analyzed and monitored before it can be executed.
With plugin the request is scanned on the server where the WordPress is installed. The miniOrange Firewall is initiated before Wordpress is initiated which means every request reaching the website will first be scanned by miniOrange Firewall and then passed to WordPress. So any genuine request is passed to the WordPress and a malicious request is stopped from moving forward. This WordPress is safe and secure.
When you use a Firewall plugin on WordPress the request reaches the server after which it is scanned and then the action is taken. While this is good for a new website or any website with low traffic but is never enough medium to large scale website with a lot of traffic.
In this solution, WAF and your website will be on two different servers. The frontend server will be your WAF will accept all the requests and pass the only genuine request to the backend server where your site is hosted. Here no one but only frontend servers are aware of the Backend server address. So any malicious request is stopped on frontend server and the attacker will never know about the backend server with the actual website.
This solution works exactly as the On-Premise solution with the only difference being the frontend server which will be a miniOrange server where all the requests would arrive and miniOrange will forward the genuine request to the corresponding website server. You will configure your website where the request will be sent from miniOrange Cloud WAF. With multiple servers across the globe the request will pass from the nearest server making it fast and efficent.
Websites are one of the most used applications in the current world and at the same time preferable choice of the hacker for the attack. The websites contain a huge amount of sensitive data and this reason makes it favorable for the attacker to steal information.
It was developed by a team at Yale University, which was later a project maintained by JASIG, and after that was merged into Apereo Foundation which now owns and maintains CAS. Apereo Foundations provide a multitude of software that is focused for educational institutions, and CAS is one among the solutions they offer.
There are many types of attacks on websites. Some of them are:
These are the topmost attacks that can make a huge impact on the website. These are used for different purposes. Read More.
