Step-by-step explanation:
The OCI security service that your IT team should use to protect the web-based marketing site against Cross-Site Scripting (XSS) and SQL Injection is the Web Application Firewall (WAF).
A WAF helps to inspect and filter web traffic, detecting and blocking malicious requests that attempt to exploit vulnerabilities like XSS and SQL Injection. It can identify and prevent unauthorized attempts to access or manipulate the website's data and code.
By implementing a WAF, your IT team can add a crucial layer of protection to the marketing site, safeguarding it against common web-based attacks and ensuring the integrity and security of the site and its data.
