How Does Web Application Security Work?
Developers utilize different strategies to mitigate vulnerabilities. Below are key methods:
1. Web Application Firewall Solutions:
Web Application Firewalls (WAFs) combine hardware and software technologies to proactively thwart web app attacks on applications without altering them in any way. This approach effectively blocks cyber threats without altering the current application setup.
There are three primary types of WAFs, software-based firewalls (SWAFs), hardware firewalls, and cloud firewalls. When an intruder attempts a cyberattack, an incoming cyberattack detection firewall analyzes traffic before quickly activating its Block feature to thwart future attempts at infiltration.
Implementing WAF security is crucial for protecting applications residing either online or in the cloud.
2. DDoS Protection:
DDoS (Distributed Denial of Service) protection can block users’ access to websites by disrupting network operations or services, which serves to defend servers against attacks while protecting network and traffic-directing mechanisms. There may also be considerations when applying DDoS protection in web apps versus websites:
Web applications often incorporate complex functions and interaction points that necessitate an in-depth evaluation and understanding of application behavior.
Websites typically feature either static or dynamic content, so DDoS protection must focus on traffic filtering and rate limiting at the network level to maintain consistent availability during high-volume attacks.
3. DNS Filtering:
The Domain Name System (DNS) acts as an internet directory. It blocks access to forbidden websites by analyzing their IP addresses, protecting web applications against potential risks.
Web application cybersecurity involves numerous strategies and techniques, such as web app vulnerability scanning, cookie management, traffic visibility, user authentication, access control management, and IP denylisting.
Now that you understand how to prevent web app attacks, explore various types of web app security in order to strengthen your defenses effectively.
