Minor erros and missing pages on "A10:2017-Insufficient Logging & Monitoring" page

[afonsobaco]

As it uses the & character, the name of the file for the page is A10_2017-Insufficient_Logging%26Monitoring.md, but when you are ON the page, the view on github link seems to be broken (404).

The correct URL (Found on the project main page) is https://owasp.org/www-project-top-ten/2017/A10_2017-Insufficient_Logging%2526Monitoring.

The second issue is the https://www-01.ibm.com/common/ssi/cgi-bin/ssialias?htmlfid=SEL03130WWEN& link on average of 191 days on the same page. The link leads us to a "Deleted or moved" page. As the information about the amount itself is not wrong, it's from 2016, therefore, I believe it's not up to date with the Ponemon institute.

(Sorry if I posted this in the worng place)
