You can easily set up your ASA Firepower Module

in this step-by-step guide

This guide provides information about basic configuration of security policies (ac-

cess control policies) on the Cisco ASA Firepower module, using the Cisco Adap-

tive Security Device Manager (ASDM). Before proceeding, make sure that you have

completed the initial configuration of the Cisco ASA with Firepower Services, refer

to the separate "Cisco ASA with Firepower Services Easy Setup Guide" and so on.

Some configurations in this guide require having optional licenses installed. In those

cases, "MEMO" or "Caution" columns specify the necessary licenses.

The Cisco ASA with Firepower Services ship with a base license for Application

Visibility and Control (AVC). Optional subscriptions for Next-Generation IPS

（N-

GIPS）

, Cisco Advanced Malware Protection

（AMP）

, and URL Filtering (URL) can

be added to the base configuration for advanced functionality.

●AVC

：

Supports more than 3,000 application-layer and risk-based controls that

can launch tailored intrusion prevention system (IPS) threat detection policies to

optimize security effectiveness.

●NGIPS

：

Provides highly effective threat prevention and full contextual awareness

of users, infrastructure, applications, and content to detect multivector threats

and automate defense response.

●AMP

：

Delivers inline network protection against sophisticated malware and Cisco

Threat Grid sandboxing.

●URL

：

Adds the capability to filter more than 280 million top-level domains by risk

level and more than 82 categories.

Redirect traffic to the ASA Firepower module by creating a service policy on the

ASA that identifies specific traffic that you want to send.

Create file policies to configure the system to perform malware protection and file

control as part of your overall access control configuration. The file policies that

you create here will be used in ”2-2 Configuring Access Control Policy: Visual-

ization”.

The [New File Policy] pop-up

window appears.

5Enter a name for your new

policy in the [Name] field.

6Click [Store ASA Fire-

2Configuring Security Policy

7Click [Add File Rule].

The [Add File Rule] pop-up win-

dow appears.

8Click [Block Malware]

from the [Action] drop-

down list.

scription.

11 Click [Store ASA Fire-

POWER Changes].

12 Click [Store ASA Fire-

POWER Changes].

The [Apply Access Control Poli-

cy] pop-up window appears.

Caution

At step ❽, the rule actions [Malware Cloud Lookup].and

[Block Malware] require the NGIPS License or the AMP

License. If you donʼt have these licenses, select the rule

actions [Detect Files].or [Block Files].

●Detect Files rules allow you to log the detection of

specific file types while still allowing their transmis-

sion.

●Block File rules allow you to block specific file types.

●Malware Cloud Lookup rules allow you to log the

malware disposition of files traversing your network

based on a cloud lookup, while still allowing their

transmission.

●Block Malware rules allow you to calculate the SHA-

256 hash value of specific file types, then use a cloud

lookup process to first determine if files traversing

your network contain malware, then block files that

represent threats.

MEMO

You can set separate rules within a file policy to take different actions for different file types,

application protocols, or directions of transfer. If you want to do so, repeat the steps ❼to ⓫.

By editing the [Default Allow All Traffic] policy that the system provides by default,

configure access control rules to exert granular control over network traffic logging

and handling (visualization).

2-2 Configuring Access Control Policy: Visualization

7Select the policy name of

the step 2-1 ❺from the

[File Policy] drop-down

list.

8Click [Logging].

Caution

At step ❻, the intrusion policies [Connectivity Over Security] and so on require the NGIPS Li-

If you do not specify a reputa-

tion level, the system defaults to

[Any], meaning all levels.

12 Click [Logging].

1Click [Add Rule].

The [Add Rule] pop-up window

appears.

Because the [Default Allow All Traffic] allows all traffic through, configure access

control rules to block specific traffic, for example, application or web traffic that is

high risk or has low business relevance.

2-3 Configuring Access Control Policy: Blocking

13 Click [Log at Beginning

and End of Connection].

14 Click [Add].

Caution

At step ❿, the URL reputation requires the URL License. And you can only select one reputa-

tion level. Selecting a reputation level also selects all reputations more severe than that level.

For example, if you configure a rule to block [Suspicious sites] (level 2), it also automatically

blocks [High Risk] (level 1) sites.
