This example of a script injection attack would be best mitigated by input sanitization. Input sanitization involves cleaning or filtering user inputs to ensure that they do not contain harmful data, such as malicious scripts. This prevents attackers from executing script-based attacks (e.g., Cross-Site Scripting or XSS).
* Nmap command is unrelated to input sanitization, as it is a network scanning tool.
* Email phishing attempts require different mitigations, such as user training.
* Browser warnings about insecure connections involve encryption protocols, not input validation

Data leaks are most likely to cause reputational damage because they expose sensitive information and can reduce customer, partner, and public trust in the company.

Tokenization is a process that replaces sensitive data, such as credit card information, with a non- sensitive equivalent (token) that can be used in place of the actual data. This technique is particularly useful in securely storing payment information because the token can be safely stored and transmitted without exposing the original credit card number.

ARP poisoning is a relatively simple attack that can be executed with readily available tools, making it most likely associated with an unskilled attacker rather than advanced or credential- based threats.

RADIUS provides centralized authentication, authorization, and accounting, and it can integrate with an LDAP database to authenticate users connecting to the company's wireless network.
