A lot of people would come up with different explanations about what WAF means. The bottom line is that, WAF stands for “virtual firewall.” It is an internet application security appliance that gives web based application security. WAF has several advantages over traditional firewalls.
In order to understand what WAF security architecture is all about, it is important to understand the way WAF works. Basically, WAF is a web-based application security appliance that offers web application firewall protection. WAF actually resides on Virtual Private Networks (VPS). VPS allow a single physical server to run various different operating systems, and each of these servers can be used by any number of web applications. Thus, by using a VPS, web applications can run multiple virtual environments each with its own level of security and privacy.
As we have seen above, Virtual Private Networks (also called VPLs) provide a great deal of flexibility for the administrator to deploy different levels of security and to avoid single points of failure. To that end, WAF can be configured to “try” to detect all failures and to eliminate them. However, a traditional firewall would do something similar. It would try to detect each failed connection and then stop that particular application from accessing the Internet. That is why the goal of a WAF, and of any good firewall in general, is to eliminate or prevent the unauthorized access from a specific application.
With WAF, the administrator can configure and define how often the firewall scans the physical layer of the computer system. In other words, he or she can configure the scan to occur on a random interval or to occur at a specific time. If a WAF detects an error, it will notify the administrator or the computer system manager about it. The virtual patching technology provides a way to quickly fix those errors, so that your network does not suffer from an outage due to that single point of failure.
Today, many companies are deploying WAFs to protect their web applications from damage caused by viruses, worms, hackers, and malware. A single point of failure in the infrastructure can cause catastrophic damage to a business. An employee can accidentally download a virus or a Trojan virus onto his or her computer. This downloaded program can then be used by the hacker to infiltrate your database and to perform a variety of tasks. By implementing WAF, you can prevent this type of threat from attacking your company, and that can help to protect your company’s data and your operations.
When a business adopts the use of web application firewalls, they will be able to proactively monitor all of the files that are being sent and received on their network. They will be able to see exactly which employees have visited that website. If there is any suspicious activity, the security architecture will send an alert to the administrator. They will be able to block the websites and users, and to identify the IP address or domain that the malicious programs are coming from. Once they have been identified, the administrator can then take appropriate action to stop the malicious software. By preventing the distribution of hostile software, the web security architecture can do a lot to improve the overall safety of your company.
Web application security is especially important if you are using a computer system that is connected to the Internet for your business. Any malicious software that is transmitted over the Internet can easily gain access to your computer system. It might be transmitted in the form of a virus, worm, or Trojan program. If a malicious program is attached to a legitimate piece of software, the firewall will often be unable to detect the attack, and will simply return false results. If a virus or other intruder is able to bypass this type of firewall, the application security measures that were designed to detect and prevent the transmission of hostile software will not work to protect your computer system.
To prevent attacks from people and viruses, you should deploy a WAF architecture across your entire system. Each individual component of the WAF should be designed to avoid common vulnerabilities that could allow an intruder to penetrate the network. Each part of the architecture should be evaluated for vulnerabilities before it is deployed, and patches will be available if vulnerabilities are found. Proper deployment of the WAF will help you avoid the risk of a system-wide vulnerability and the loss of data.
