Information

Mobile code is defined as software modules obtained from remote systems, transferred across a network, and then downloaded and executed on a local system without explicit installation or execution by the recipient. Examples of mobile code include JavaScript, VBScript, Java applets, ActiveX controls, Flash animations, Shockwave videos, and macros embedded within Microsoft Office documents. Mobile code can be exploited to attack a host. It can be sent as an e-mail attachment or embedded in other file formats not traditionally associated with executable code.

While the IDPS cannot replace the anti-virus and host-based IDS (HIDS) protection installed on the network's endpoints, vendor or locally created sensor rules can be implemented, which provide preemptive defense against both known and zero-day vulnerabilities. Many of the protections may provide defenses before vulnerabilities are discovered and rules or blacklist updates are distributed by anti-virus or malicious code solution vendors.

Solution

To create an Antivirus Profile:
Go to Objects >> Security Profiles >> Antivirus.

Select 'Add'.

In the 'Antivirus Profile' window, complete the required fields.

Complete the 'Name' and 'Description' fields.

In the 'Antivirus' tab, for all Decoders (SMTP, IMAP, POP3, FTP, HTTP, SMB protocols), set the 'Action' to 'deny', or 'reset-both'.

Select 'OK'.

Use the Profile in a Security Policy:
Go to Policies >> Security.

Select an existing policy rule or select 'Add' to create a new one.

Use the Antivirus Profile in a Security Policy applied to traffic from an outside (untrusted) zone.

Go to Policies >> Security.

Select an existing policy rule or select 'Add' to create a new one.

In the 'Actions' tab in the Profile Setting section:
In the 'Profile Type' field, select 'Profiles'. The window will change to display the different categories of Profiles.

In the 'Antivirus' field, select the configured Antivirus Profile.

In the 'Anti-Spyware' field, select the configured Anti-Spyware Profile.
