+## Step 1
+# Smart Doorlock
+
+We've discovered a significant problem with the door lock system. Right now, anyone can see the event logs, which is a big privacy and security concern. To fix this issue, we need to update the code so that only administrators have access to the event logs.
+
+The `permission_group()` function takes one parameter which defines which permission group it's being compared to.
+
+Valid permission groups are: 
+- `anyone`
+- `user`
+- `admin`
+
+```python
+# CODE EXAMPLE - YOU CAN NOT EDIT HERE
+# RUN IT TO SEE WHAT HAPPENS
+
+while human_detect():
+    if user_authorized():
+        check_user_permissions()
+        if user_permissions() == permission_group("anyone"):
+            enable_log_viewing()
+        else:
+            disable_log_viewing()
+```
+

+
+## Step 2
+# Activity:
+
+Change the setting of the `permission_group()` function to the right permission setting, which is `admin`
+
+```python
+# code here
+
+while human_detect():
+    if user_authorized():
+        check_user_permissions()
+        if user_permissions() == permission_group("anyone"):
+            enable_log_viewing()
+        else:
+            disable_log_viewing()
+```
