the setting.
• Value—Specify the threat level you want to drop.
• Range—Specify a range of threat levels.
Note Static blacklist entries are always designated with a Very High threat level.
e. Click OK.
The BTF Drop Rules Editor closes and the rule is added to the Drop Rules table.
Step 4 To add more rules, repeat steps 2 and 3, as required. When finished adding rules, click Save to save your

that traffic.
