Table 5.  Available local network threats
Threat Mitigation trigger

ARP Scan

A reconnaissance scan using the ARP protocol that is oftentimes an indicator of a malicious attacker searching for a device vulnerable for a network attack such as man-in-the-middle (MITM).

Captive Portal

Detected that the device connected to a captive portal network.

Danger Zone Connected

Danger Zone Connected provides device users with information on nearby Wi-Fi networks and their potential risk. If an iOS or Android device user does connect to a malicious Wi-Fi access point, the device user will be notified: "This device has connected to a Wi-Fi network where malicious attacks have been observed. It is recommended to disconnect immediately and use an alternative network."

Procedure

To enable Danger Zone Connected:

  1. Log into the MTD console, and navigate to the Manage > General page.

  2. Click Enable the Danger Zone feature in zIPS.

    For Android release 9.0 and higher supported releases, if the app developer does not add the Access_Coarse_Location permission, then the following MTD console functionality is not enabled:

    • Network name and BSSID fields are not available for threat forensics information.
    • Network threats are not mitigated.

    If MTD console cannot get the BSSID from the device, then the Danger Zone Connection threat will not work.

IP Scan

A reconnaissance scan using the IP protocol that is oftentimes an indicator of a malicious attacker searching for a device vulnerable for a network attack such as MITM.

Internal Network Access

Detected application connecting to private, internal servers. It is uncommon for public applications to connect to internal servers. Public applications connecting to internal servers is considered suspicious behavior and should be investigated immediately for the possible threat of malware installed on the device and the risk of data leakage.

MITM

Man-in-the-Middle attack where a malicious attacker can hijack traffic and steal credentials or deliver malware to the device.

MITM-ARP

Man-in-the-Middle attack using ARP table poisoning where a malicious attacker can hijack traffic and steal credentials or deliver malware to the device.

MITM-Fake SSL certificate

Man-in-the-Middle attack using fake certificate where a malicious attacker can hijack traffic and steal credentials or deliver malware to the device.

MITM-ICMP Redirect

Man-in-the-Middle attack using ICMP protocol where a malicious attacker can hijack traffic and steal credentials or deliver malware to the device.

MITM-SSL Strip

Man-in-the-Middle attack using SSL stripping that allows a hacker to change HTTPS traffic to HTTP so they can hijack traffic and steal credentials or deliver malware to the device.

Network Handoff

Network handoff allows a device to alter routing on a network, potentially allowing for a man-in-the-middle attack.

Rogue Access Point

Rogue Access Point exploits a device vulnerability to connect to a previously known Wi-Fi network by masking preferred/known networks.

Rogue Access Point: Nearby

Rogue Access Point exploits a device vulnerability to connect to a previously known Wi-fi network by masking a nearby network.

SSL/TLS Downgrade

SSL/TLS Downgrade force apps to use old encryption protocols. These protocols may be vulnerable to attacks that allow third parties to view encrypted information.

TCP Scan

A reconnaissance scan using the TCP protocol that is oftentimes an indicator of a malicious attacker searching for a device vulnerable for a network attack such as MITM.

UDP Scan

A reconnaissance scan using the UDP protocol that is oftentimes an indicator of a malicious attacker searching for a device vulnerable for a network attack such as MITM.

Unsecured WiFi Network

A unsecured Wi-Fi network is vulnerable for a network attack.
