Spyware

Overview

Cisco Cloud Web Security provides protection from spyware and web viruses.

Cisco ScanCenter enables you to create approved lists of applications that will bypass spyware filtering and websites that will bypass web reputation filtering. By default, all incoming adware, spyware, and potentially unwanted applications (PUAs) are blocked. If, for some reason, an administrator requires a specific PUA to be permitted, it can be selected in an approved list. All PUAs are registered in the approved list when a download request is received.

All truly malicious code, such as viruses, worms, Trojans, back-doors, and key loggers are automatically blocked. Similarly, all known phishing exploits are automatically blocked by Cisco Cloud Web Security. The approved list applies to “grayware” which typically includes applications that hijack web browsing activities, redirect users to sponsored sites, monitor non-confidential browsing habits, create unwanted pop-up adverts, and so on.

Allowing Applications Classified as Potentially Unwanted

With the spyware allowed list you can allow applications that Cisco has classified as potentially unwanted.

Procedure

Step 1

Click the Spyware tab.

Step 2

In the Whitelists menu, click Spyware to display the Spyware page.

Step 3

Select the check boxes of the spyware to allow. You can enter part or all of the name of a spyware application in the Search box to find a spyware application.

Step 4

Click Submit to apply your changes. Alternatively, navigate away from the page to abandon your changes.

Password Protected Archives

Cisco Cloud Web Security scans the files inside archives, such as zip files, for malware. However, it cannot scan password-protected (encrypted) archives. Because these archives could contain malware, they are classified as PUAs. However, you can enable users to access these files by selecting the Protected Archive check box in the Approved List.

Caution
Enabling access to protected archives will globally allow all users to access these archives, which may contain PUAs.

Excluding Websites from Web Reputation Filtering

By default, Cisco Cloud Web Security blocks websites with a poor Web reputation score. You can prevent specific websites from being blocked by adding them to an allowed list. You can add a maximum of 1000 websites to the list.

Procedure

Step 1

Click the Spyware tab.

Step 2

In the Whitelist menu, click Web Reputation to display the Web Reputation page.

Step 3

Enter the required URL in the URL field. The URL can be a maximum of 256 characters in length.

Step 4

Click Add URL.

What to do next

You can click Check Reputation to open the SenderBase page for the website.

To remove a website from the allowed list, enter part or all of the URL in the Search box. Select the check box then click Remove.
