If you want to protect your website and save yourself time, the most effective solution is a WAF or application firewall. The latest studies say that this market will grow 18% until 2021. Are you going to be the last to protect your Web?
1. How does a firewall differ from a WAF or application firewall?
A firewall is an element that ‘blocks’ accesses. A WAF is specifically designed to do this function in the application layer 7 of the OSI layer. That’s where the content of your website is. This means that while a firewall works at level 3 (IPs) WAF reaches the level of content can control if someone tries to attack your web or application by domain or tries to burst your system of passwords.
2. Does a WAF protect me from attack applications?
Yes, brute force attacks automated attacks of spambots or targeted attacks. Any attack made from another terminal or terminals. That is precisely its main function.
3. Does it protect me from a DDoS?
Yes, whenever it is a layer 7 WAF, it protects you from such attacks.
4. If I have a WAF or application firewall I will not have to clean malware or infections ever?
Of course you will have to clean a lot less malware, but as we said, something as simple as send the administrator password by email, or that someone sees it or hack your computer to read your keyboard, put you at risk. And if you do not take extra security measures, you can do nothing more than detect the malware as soon as possible and clean it.
5. Does a WAF protect me from data theft or passwords?
If the attack is by brute force or automated, yes. However, if you give that data to someone unsecured or just someone sees it while you type it, the WAF will not be able to do anything, since it would be a ‘lawful’ access. For these cases it is important to be fully aware of the critical data of your website and be careful in its maintenance.
6. Does it make sense to hire a WAF or application firewall in a timely manner at important times?
There are services like the detection and cleaning of malware that is recommended to have as maintenance, but can be contracted in a timely manner. A protective service would not be the same case. Promptly hiring a protection service protects you exclusively during that time. At the moment it is not active, all spambots and attack attempts can and probably infect your web.
7. What does the WAF have to do with updates and vulnerabilities?
A WAF can be an extra protection, although also considered a patch, if you have known vulnerabilities. Maybe you have customized a plugin and it is very expensive to update it or maybe the author has not yet fixed a serious and known vulnerability that has started to be exploited.
8. Is the WAF or application firewall for all types of websites?
Yes, webs with own development, e-commerce, blogs, online applications, made on WordPress, Joomla, Drupal or any CMS.
9. How is a WAF service different from a WAF plugin?
Plugins that include a WAF can block certain things but not at the same level as a WAF. And above all, they act once your web has already received the malicious request. Being configured within the web, the blocking occurs from within, consuming resources.
10. Does the performance of my website improve with a WAF or application firewall?
Yes. By preventing malicious requests from reaching your web site that you do not have to receive or respond to. Besides not receiving attacks that can saturate your resources in a timely manner, it will help your web performance improve and be adequate.
