Microsoft Defender for Microsoft 365 ships with a set of default security controls that can be applied right out of the box. These security controls – known as Microsoft Defender preset security policy – are especially useful for SMBs (small and medium businesses) that lack the budget to hire security expertise needed to configure organization-specific security policies.
The Microsoft Defender preset security policy is split into three categories:
Note: Both standard and strict protection policies are not turned on by default. They work on top of the built-in protection. They are responsible for dealing with advanced security threats. You can also have both Standard protection and Strict protection turned on for your tenant as these security settings can be applied on a user, group, or domain basis.
You can access the Microsoft Defender Preset Security Policy in the following two ways:
Note: You can access the Microsoft 365 Security Center [or Microsoft Defender portal] only if you have been assigned the Global Administrator or Security Administrator role.
The built-in protection of preset security policy is potent enough to safeguard organizations against various cyber-security threats. However, on its own, it may not be able to handle the speed at which the cyber-threat security landscape evolves. For this, you will need a more-tailored approach which is offered only by standard or strict protection security setting.
However, if baseline security is what you are after, then built-in protection will do. With this, you get a low-impact version of safe attachments and safe links policy. You also get baseline protection against malicious emails and malware. But, bear in mind, that built-in protection working with standard/security protection is always more powerful than built-in protection working on its own.
The easiest way to test whether the built-in protection setting is working or not is by testing out safe attachments and safe links policy.
Now that you know your Microsoft 365 tenant is secure – thanks to Microsoft Defender’s built-in protection – in the next article, let’s understand how you can further harden your tenant’s security by turning on the preset standard and strict protection policies.
It is best to read the articles in the order they are written. And since Microsoft 365 security is a vast topic, remember to watch out for this corner for new articles every week.
