F5 irule to Protect Clickjacking Attack using X-FRAME-OPTIONS
Secure Clickjacking Attack with X-Frame-Options using F5 iRule
There are multiple ways to add X-Frame-Options header in your web applications. However, implementing through F5 load balancer is probably the easiest one.
By doing at a network edge using F5 iRule give you the advantage of making changes no fly.
That’s right; you don’t need to restart any services hence no downtime.
There are three settings for X-Frame-Options:
- SAMEORIGIN: This configuration will allow the page to be displayed in a frame on the same origin as the page itself.
- DENY: This setting will prevent a page displaying in a frame or iframe.
- ALLOW-FROM uri: allow resources to load only on the specified origin.
To implement in F5 irule
- Create irule with following
when HTTP_RESPONSE {
HTTP::header insert "X-FRAME-OPTIONS" "SAMEORIGIN"
}
- Associate this irule to respective Virtual server
To verify
Use browser’s inbuilt developer tools to examine the response headers or online using HTTP Header checker tool.
You see it’s three-line which does the job!
