Pen test Remediation required - Enable HSTS and Hide Email server type / version

FME Flow 2023.2.1
Build 23774

I’m planning on upgrading FME Form / Flow this weekend which includes fixing the following vulnerabilities detected from our internal Pen Test.

USR-640 Email Servers Advertise Software Type and Version 

Removing the software banner from the email server is typically done in the configuration file, for example sendmail.cf or postfix.conf.

Is it possible to fix this and where would the file(s) be located?

What change should take place?

USR-622 HSTS Missing from HTTPS Server

Is it simply enough to add the following to the web.xml config file?

<!-- Enable HSTS   -->
<filter>
    <filter-name>httpHeaderSecurity</filter-name>
    <filter-class>org.apache.catalina.filters.HttpHeaderSecurityFilter</filter-class>
    <init-param>
        <param-name>hstsEnabled</param-name>
        <param-value>true</param-value>
    </init-param>
    <init-param>
        <param-name>hstsMaxAgeSeconds</param-name>
        <param-value>31536000</param-value>
    </init-param>
    <init-param>
        <param-name>hstsIncludeSubDomains</param-name>
        <param-value>true</param-value>
    </init-param>
    <init-param>
        <param-name>hstsPreload</param-name>
        <param-value>true</param-value>
    </init-param>
    <init-param>
        <param-name>antiClickJackingOption</param-name>
        <param-value>ALLOW-FROM</param-value>
    </init-param>
    <init-param>
        <param-name>antiClickJackingUri</param-name>
        <param-value>https://OUR_PRIMARY_DOMAIN.HERE</param-value>
    </init-param>
    <async-supported>true</async-supported>
</filter>

<!-- Enable HSTS Filter  -->
<filter-mapping>
    <filter-name>httpHeaderSecurity</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
</filter-mapping>

I’m able to check if HSTS is enabled using my own PowerShell script thereafter as I did for my other servers.
