CSP is a browser policy
Content Security Policy is delivered to the browser, usually as an HTTP response header. It tells the browser which sources are allowed for scripts, styles, images, frames and other resource types.
Why it helps
If an attacker finds a way to inject content into a page, a well-designed CSP may prevent some injected resources from loading or scripts from executing. It is not a replacement for fixing the underlying vulnerability.
A CSP can also reveal architecture
Even before judging whether the policy is strong, the list of permitted sources can reveal how many external providers the application depends on. Very broad wildcards or many third-party domains deserve review.
Observe the policy and the page together
Scantide Observe shows CSP-related evidence alongside scripts, iframes and contacted hosts. That makes it easier to compare the policy with what the page actually loads.

This automated scan detects common vulnerabilities but cannot identify all security risks. Results may contain false positives or miss certain vulnerabilities. Always verify findings manually and implement additional security measures.
Historical source · JufCorp: Securing your servers, users and customers onlineA 0day is a security bug in the software of the server your running and they vary on how much impact they may have. The name comes from that it is day 0 of it's public release and the manufacturer, in this case Microsoft, hasn't released any patch against it leaving you vulnerable no matter what you do. Some of them are even just a nifty way of adding stuff (specific strings ) to the URL or the service the attacker wants to reach and bypassing all of the built in security by "fooling" the server. Whatever they do, keep track of when they surface and see what can be done to mitigate them.
Enforce an Account Lockout Policy and enforce complex password. Yes, people will hate you but they will hate you even more if someone actually succeeds in hacking your users data. Have a look at the link above about Account Lockout Policies though. Do not have local users more than necessary on the Exchange Server itself.
