Salesforce Health Check Custom Baseline

Salesforce Health Check Custom Baseline

Introduction

The Salesforce Health Check has been around for a year or so now, debuting in the Spring 16 release of Salesforce (and bearing a striking resemblance to an app exchange listing with the same name).  The Salesforce Help topic gives chapter and verse on this so I’m not going to spend any time on the basic functionality, except to say that it’s a great tool for allowing you to see at a glance how your Salesforce org shapes up security-wise. There has been one caveat though, the baseline it is compared against is set by Salesforce not you, which means that if your security standard differs from the one true path you’ll see warnings and errors. As anyone who has accepted a unit test failure for more than one build knows, as soon as people expect errors they stop counting how many there are. Thus you may start out accepting a single warning, before you know it you have a number of potential security problems which are being ignored because “that page always shows errors”.

Custom Baselines

Spring 17 introduced the beta of custom baselines - this allows you to deviate from the Salesforce standard and supply your own baseline which reflects your security requirements. From now on if your Health Check page shows an error or exception, that means you have a real security issue and need to deal with it quickly.

While you could create a custom baseline from scratch, the easiest way is to export the standard baseline and amend it. Navigate to Setup -> Security Controls -> Health Check and click the gear icon, then ‘Export XML’ from the resulting context menu:

This downloads the baseline to a file named ‘baseline.xml’ (or baseline (1,2,3,etc).xml if you keep downloading it to the same place on a mac!), which you can then open in your favourite editor - I like Atom for XML files. Again, the Salesforce Help does a great job of explaining the format of the XML file so I’m not going to cover this. A couple of things to bear in mind:

  • You must change the Name and DeveloperName of the Baseline element, otherwise you’ll be trying to overwrite the standard, which you can’t do.
  • When you import the file, do it via the Lightning Experience. If you try this in class and you get an error you get no information that an error has occurred. According to the help “If your import fails, you receive a detailed message in Lightning Experience to help you resolve the problem”, which is pretty big talk when the actual message is Screen Shot 2017 04 22 at 16 03 16

Changing the Baseline

One area where my dev org is considered substandard is the password expiration time. I have my passwords set up never to expire, as forcing users to change their passwords regularly often results in them choosing predictable passwords that are easier to break. The Salesforce health check standard generates a Medium Risk alert if the value is over 90 days and a High Risk alert if the value is over 180 days.

Here’s the section of the file that configures this:

If I change the standard value to the numeric equivalent of Never Expires, 2147483647.0, and the warning to one higher:

and import the updated XML file using the context menu shown above, I can then switch my Health Check to the custom baseline and my password expiration is now at a satisfactory level:

I am not a security consultant

Notwithstanding the fact that forcing users to change their passwords regularly is out of favour in some places, you should not take this post as my advising you about your password policies in any shape or form. If you base your security settings on things that you read in random blog posts then best of luck to you - I did it in a dev org to show the functionality as there’s nothing that I really care about in there.

I’d expect the majority of custom baselines to be making the security standard more restrictive, in regulated industries for example, but what you should set up is a baseline that aligns with your corporate security policies.

Here comes the wish list

Anyone familiar with my blogs or Medium stories knows that I usually have a wish list around Salesforce functionality, so if any product managers are reading this, here’s what I’d like to see:

  • A way to email out the health check, run against a custom baseline, on a schedule. Security and compliance departments can receive this first thing in the morning and spend the day focusing on other systems.
  • Notifications when the health check result changes - if my Evil Co-Worker blags admin rights and changes the configuration to allow previous passwords to be re-used, I want to know about it. (Ideally I’d receive an automated report at the end of every day detailing everything the Evil Co-Worker has done, but that might be asking too much).
  • A way to snapshot the health check output regularly, so that I can see if an org is trending towards a more or less baseline compliant security setup. 
  • Custom entries - for example, I can easily spin through the ApexClass sobjects and figure out how many aren’t using ‘with sharing’. Security isn’t just about configuration, it’s also about code!

Lightning Design System in Visualforce Part 3 - Built In SLDS

Lightning Design System in Visualforce Part 3 - Built In SLDS

Apexslds

Overview

In the past, using the Salesforce Lightning Design System (LDS) in Visualforce (or Lightning Components for that matter) required downloading the latest version from the home page and uploading it as a static resource to each Salesforce org that you wanted to use it on. I dread to think how many copies of exactly the same zip file have been uploaded over the last 18 months or so, but I’d imagine a significant amount of storage is currently dedicated to just this purpose. Probably only beaten out by a million copies of jQuery and Bootstrap. In the Spring 17 release of Salesforce, this is no longer the case - a single Visualforce tag can now do the heavy lifting for you.

The SLDS Tag

Simply adding <apex:slds /> to your page and nesting your markup in a div styled with the slds-scope class, and you are good to go. For example, the following page:

<apex:page showHeader="false" sidebar="false" standardStylesheets="false"
           standardController="Account" applyHTmlTag="false">
    <html xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
        <body>
            <apex:slds />
            <div class="slds-scope">
                <div class="slds-page-header" role="banner">
                    <div class="slds-grid">
                        <div class="slds-col slds-has-flexi-truncate">
                            <div class="slds-media slds-no-space slds-grow">
                                <div class="slds-media__figure">
                                    <svg aria-hidden="true" class="slds-icon slds-icon-standard-account">
                                        <use xlink:href="{!URLFOR($Asset.SLDS,
'/assets/icons/standard-sprite/svg/symbols.svg#account')}"></use> </svg> </div> <div class="slds-media__body"> <p class="slds-text-title--caps slds-line-height--reset">Account</p> <h1 class="slds-page-header__title slds-m-right--small slds-align-middle slds-truncate"
title="{!Account.Name}">{!Account.Name}
</h1> </div> </div> </div> </div> <ul class="slds-grid slds-page-header__detail-row"> <li class="slds-page-header__detail-block"> <p class="slds-text-title slds-truncate slds-m-bottom--xx-small" title="Description">
Description
</p> <p class="slds-text-body--regular slds-truncate" title="{!Account.Description}">
{!Account.Description}
</p> </li> <li class="slds-page-header__detail-block"> <p class="slds-text-title slds-truncate slds-m-bottom--xx-small" title="Industry">
Industry
</p>{!Account.Industry} </li> <li class="slds-page-header__detail-block"> <p class="slds-text-title slds-truncate slds-m-bottom--xx-small" title="Visualforce">
Visualforce
</p>No static resources were used! </li> </ul> </div> </div> </body> </html> </apex:page>

renders as:

which is pretty cool, and makes throwing a page together to test out some ideas in a new org a lot easier than it has been.

What about Images?

Without the LDS static resource, image references need to be handled a slightly different way, via the $Asset global. Use this wherever you’d use your static resource previously. E.g. in the example markup above, I use the $Asset global as follows:

<svg aria-hidden="true" class="slds-icon slds-icon-standard-account">
   <use xlink:href="{!URLFOR($Asset.SLDS, '/assets/icons/standard-sprite/svg/symbols.svg#account')}"></use>
</svg>

although continuing the pattern of making sure SVG is difficult to use, you have to add a custom namespace to the page:

<html xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">

and you can’t do that unless you turn off the standard Salesforce header, sidebar and stylesheets. If you see an SVG on a Salesforce page in the wild, take a moment to appreciate the hoops that the developer jumped though in order get it there.

So no more static resources?

Well that depends. The SLDS tag always pulls in the latest version of the Lightning Design System, so much depends on whether you want that behaviour.It means that things may change underneath you, possibly in a breaking way. If it’s for your internal Salesforce org and you have people who will be able to make any changes required by the latest version, then emphatically yes. If you are building pages for a consulting customer who expects them to continue working in the future with zero effort, then maybe not. As always, there is no substitute for thinking about how the application will be used, both now and in the future.
