Predefined Policies to Detect Suspicious User Activity

Table of Contents

Learn about the predefined policies that you can use to detect suspicious user activities.

Policies for detecting suspicious user activity are now included in the Behavior Threats feature of SaaS Security. For this reason, the following Data Security policies are no longer available for newly provisioned tenants. Because the following policies will soon be deprecated for all tenants, we recommend that you use the policies included in Behavior Threats. If you are currently using the following legacy policies, we recommend that you transition to the new policies. By transitioning to the new policies, you ensure continued functionality and access to the latest features.

Data Security provides predefined policies for detecting suspicious user activity. These activities might indicate attempts to steal or destroy data, or might indicate attempts to breach a user's account. These predefined policies are Disabled by default, but you can Enable them from the User Activities Policies page ( Data SecurityPoliciesUser Activity Policies).

If a Suspicious User Activity policy is enabled, violations of the policy are logged as incidents.

From the User Activity Policies page, you can edit the severity of a policy, but you cannot edit its match criteria. If you want to trigger policy violations based on different criteria, such as a different event count or frequency, contact customer support.

The following predefined policies are available.

Predefined Policy Name	Description
Bulk Deletion	Detects that a user deleted a large number of files or folders within a short time frame. Bulk deletion might be a malicious attempt to cause data loss. Data Security triggers a violation of this policy if a user deletes more than 20 unique files or folders within an hour.
Bulk Download	Detects that a user downloaded a large number of distinct files or folders within a short time frame. Bulk downloads might be an attempt to compromise your organization’s sensitive data. Data Security triggers a violation of this policy if a user downloads more than 20 unique files or folders within an hour.
Bulk Sharing	Detects that a user shared a large number of distinct files or folders within a short time frame. Bulk sharing might be an attempt to compromise your organization’s sensitive data. Data Security triggers a violation of this policy if a user shares more than 20 unique files or folders within an hour.
Bulk Upload	Detects that a user uploaded a large number of distinct files or folders within a short time frame. Bulk uploads might be an attempt to compromise your organization’s sensitive data. Data Security triggers a violation of this policy if a user uploads more than 20 unique files or folders within an hour.
Impossible Traveler	Detects that a user accessed an application from different locations within a time frame that could not accommodate travel between the locations. The locations are determined by IP addresses. This impossible travel might indicate that the user’s account is compromised.
Inactive Account Access	Detects that a user accessed an application by using an inactive account. An account is considered inactive if it was not accessed in over 30 days. Inactive account access might indicate that the user’s account was breached.
Login Failure	Detects multiple failed login attempts to an application by a user. Multiple login failures might indicate an attempt to breach the user account. Data Security triggers a violation of this policy if there are more than 5 consecutive failed login attempts within 30 minutes.
Malware	Detects user activity on a file that contains malware. This activity might identify a malicious user and is a threat to your organization.
Risky IPs	Detects that a user accessed an application from a suspicious IP address. Suspicious IP addresses include malicious IP addresses identified by Unit 42, the Palo Alto Networks threat intelligence team. Suspicious IP addresses also include IP addresses of known Tor exit nodes and IP addresses belonging to Bulletproof Hosting Providers (BHPs). Access from a risky IP address likely indicates that the user’s account was breached.
Unsafe Location	Detects that a user accessed an application from a country that the United States Department of the Treasury considers unsafe. These countries are considered unsafe because they are known origins of cyberattacks. User access from an unsafe location likely indicates that the user’s account was breached.
Unsafe VPN	Detects that a user accessed an application from an unauthorized or unsanctioned VPN. These unsafe VPNs include personal VPNs and known consumer VPNs. The use of an unsafe VPN might indicate that the user is hiding their IP address to avoid auditing and tracking. The use of an unsafe VPN might also indicate that a malicious actor is attempting to decrypt traffic to steal user credentials.
