With WAF security , a web application firewall serves as a primary D dos prevention mechanism. Its primary function is to block or limit the access of malicious network code to the vulnerable application server software installed on the network edge. By doing so, a secondary attack on the same vulnerable software can be thwarted before it penetrates the application server software itself. This type of security is particularly useful for companies where there is a possibility that an employee might bring home a virus to work on and use it to compromise a company's important data. The solution to this problem is to implement a secondary attack on the application server software and use a WAF to block or limit the entry of the malicious codes.
There are two common types of WAFs available to business IT departments today - Management Information Format (MIF) and Management Interface (M IA). Although most companies prefer to deploy a Management Information Format (MIF) based WAF to protect their websites against cyber threats, more businesses are deploying the more flexible Management Interface (M IA) to counter cyber threats. Using a WAF with an M IA solution allows a business IT department to easily deploy a WAF and have the WAF immediately deployed to various workstations without the additional burden of configuring each workstation to utilize the specific WAF software product from the manufacturer. The flexibility provided by the flexibility of a WAF allows a business IT department to rapidly respond to new or evolving threats and vulnerabilities to their website speedily and with minimal cost.
By combining WAF with a specially designed gateway or rack-based sniffer, a WAF can be used to detect and log malicious network code from the internet. A specially designed rack-based sniffer (RSN), which can be configured with either a remote or local forwarder or firewall, is a good WAF solution for companies with a high-traffic website. The sniffer will capture all data packets that are sent and received by the target website and save them in a secure log file. This log file can be easily accessed by a trained employee who can use it to locate any exploited vulnerabilities on the website. Using a specially designed rack-based sniffer to achieve this goal can increase website speed up to fifty percent.
A well-designed waf firewall will prevent unauthorized access to the company's network. In most cases, an internal firewall will perform well and block traffic from unauthorized sources. However, companies with many computers that access the company's network will benefit most from a dedicated third party firewall. Using a waf trueshield to accomplish this task will increase website speed up to fifty percent.
Web applications, such as e-commerce websites, must rely on efficient and robust security controls to protect themselves from threats and hackers. Using an e-commerce web application firewall will help prevent a variety of cyber threats including SQL injection attacks, PHP injection attacks and cross-site scripting attacks. An e-commerce web application firewall will also help prevent traffic from unauthorized users to important data and systems. In many cases, e-commerce companies do not have the financial resources to implement an internal firewalls and rely on third-party firewall products to provide them with effective security and reliability. Using an e-commerce web application firewall with SSL enabled sites will give businesses greater protection from hackers and more efficient and robust security measures.
Implementing a website security plan will require the expertise of qualified personnel. These personnel will develop a customized solution that incorporates their experience and knowledge to create a robust and cost effective online security measures plan. Using a combination of on-premise firewalls and WAFs with WPMU devises will provide a comprehensive protection for a company's data from all threats.
