Over the last few years, businesses of all sizes are increasingly realizing the effects of web application security. Figures already show that hacking attempts are greatest around Layer 7. So when it comes to security, web application firewall is the only solution.
While most companies and their developers think that they know what it is and how it works, there is a greater need to understand the working and distinguishing between different types of WAFs.
- There are many types of web application firewalls, but they vary greatly in terms of their ability to prevent hackers.
- Most Layer 7 firewalls fail greatly at detecting zero-day threats. They are like simple, closed boxes made to protect against a written set of rules.
- Managed web application firewall is must to block even the latest issues. Security experts keep updating the rules of such appliances, so it works proactively.
- No WAF can be ‘apply and forget’. It cannot live in isolation. You have to control and monitor it to ensure everything is working. Or else hire a security team for the job.
- Web application firewall works best when also complemented with a web application scanning solution. Scanner can find issues WAF can fix it virtually to block hackers.
- Only 23% companies use WAF effectively, most of the other view it as an added expense. But fail to understand that 70% of attacks happen at layer 7.
- Cloud WAFs are getting more important. With most companies going cloud, it is mandatory to think of the security along those lines. Make sure that you look for complete scan, WAF, DDoS, and monitoring solution on cloud.
- Paying for WAF without knowing its features or trying it out first is futile. You should utilize the trial periods to gauge business effects.
