Today, we're going to discuss Soft Access Points, or Soft APs. Can anyone tell me what they think a Soft AP might be?
Is it like creating a hotspot with a smartphone?
Great insight! A Soft AP allows a device to act as a Wi-Fi Access Point, so you can share an internet connection, much like your smartphone does.
So, it's mostly used to share the internet, right?
Exactly! However, we need to be cautious because when corporate devices are turned into Soft APs, it can lead to significant security vulnerabilities.
What kind of vulnerabilities are we talking about?
Good question! When a corporate device becomes a Soft AP, it can create an unauthorized bridge between a secured internal network and insecure wireless networks, allowing unauthorized access.
That sounds dangerous. How can we mitigate those risks?
We have several mitigation techniques, such as corporate policies prohibiting the use of Soft APs and deploying endpoint security solutions.
To summarize, Soft APs can be useful, but they pose serious risks in enterprise environments, particularly when they are not properly managed.

Quick Overview
Standard
A Soft AP allows devices to create a wireless network using an existing internet connection. However, when corporate devices are misconfigured to act as Soft APs, they can create unauthorized connections that bypass security controls, leading to data breaches and security threats.
Detailed
Detailed Summary
A Soft Access Point (Soft AP) is a configuration that transforms a device, such as a laptop or smartphone, into a Wi-Fi Access Point by utilizing its wireless adapter. This setup often serves legitimate functions, like sharing an internet connection. However, significant security risks arise when corporate devices are used as Soft APs. In these cases, the Soft AP creates an unauthorized bridge between an organization's secure internal wired network and a less secure wireless environment.
This bridging allows external users or other internal users to bypass security controls like firewalls, intrusion detection systems, and network monitoring tools, leading to unauthorized access, data leakage, and potential internal reconnaissance and attacks. Thus, meticulous mitigation strategies, such as setting corporate policies and implementing endpoint security solutions, are essential for safeguarding the integrity of an organizationβs network.

Definition of Soft AP

A Soft AP refers to a computing device (e.g., a laptop, smartphone, tablet) that is configured via software to act as a Wi-Fi Access Point. It leverages the device's wireless network adapter to broadcast a Wi-Fi network, allowing other devices to connect to it and share its internet connection or network access. This functionality is often legitimate and widely used (e.g., creating a personal mobile hotspot from a smartphone to share cellular data).
Detailed Explanation
A Soft AP is essentially a feature that allows a device, like a laptop or smartphone, to share its internet connection. When you enable this feature, your device acts like a mini Wi-Fi router, allowing other devices nearby to connect to it as if it were a traditional access point. For example, when you activate the mobile hotspot on your smartphone, you're essentially turning it into a Soft AP, enabling your friends to connect to the internet using your phone's cellular data.
Examples & Analogies
Imagine you're at a coffee shop and there's no free Wi-Fi available. You can use your smartphone to create a mobile hotspot. This is like opening a small portal of the internet for others using your phone's data, much like sharing a book with a friend who forgot theirs. You're allowing them access to something valuable using your device as the bridge.

The security concern arises when a corporate-owned laptop (or any device) that is connected to the organization's secure internal wired network is then configured to enable a Soft AP.
- Bridging Secure to Insecure: This effectively turns the corporate laptop into an unauthorized bridge between the secure, managed internal wired network and an unsecured (or poorly secured) wireless network.
- Bypassing Controls: Any external party (or another internal user) who connects to this Soft AP can then gain unauthorized access to the corporate wired network, bypassing firewalls, NIDS/NIPS, and other perimeter security controls that protect the wired segment. The Soft AP acts as an uncontrolled gateway.
Detailed Explanation
When a corporate device is turned into a Soft AP, it creates a significant security risk. This setup can connect the secure internal network to an unsecured area, allowing unauthorized users to access sensitive information and systems. Because the Soft AP bypasses regular security measures like firewalls and intrusion detection systems, it can potentially expose the organization to various cyber threats. Essentially, it opens a door in the firewall without permission, letting anyone who connects through it access everything behind that door.
Examples & Analogies
Think of a corporate office as a secured fortress with walls and guards, where no unauthorized personnel can enter. If an employee decides to open a secret door (the Soft AP) to let their friends inside without the guards knowing, suddenly anyone can freely roam inside, accessing confidential documents and sensitive areas without any oversightβputting the entire organization at risk.
Impact of Soft APs

Similar to a rogue AP, it creates an unmanaged backdoor, leading to:
- Unauthorized internal network access.
- Risk of data leakage from the internal network.
- Potential for internal reconnaissance and attacks.
Detailed Explanation
The creation of a Soft AP can lead to very serious consequences for an organization. It essentially provides an open entry point for unauthorized users, allowing them to access the internal network without going through the usual security checks. This can result in sensitive data being leaked, as external users might access private data stored on the network. Furthermore, it invites the risk of internal attacks, where malicious actors can gather information about the network structure and exploit vulnerabilities.
Examples & Analogies
Imagine that a treasure chest in a castle holds all of the kingdom's secrets. If a castle resident carelessly leaves the treasure chest unlocked and invites random visitors in, anyone could take valuable items or learn the castle's secrets. In this scenario, the unlocked chest represents the Soft AP, and the visitors could be anyone from well-meaning colleagues to thieves looking to steal valuable information.
Mitigation Techniques for Soft APs

To prevent the security risks posed by Soft APs, several mitigation techniques can be implemented:
- Corporate Policy: Establish clear and strictly enforced policies prohibiting employees from enabling Soft AP features on corporate devices, especially when connected to the wired network.
- Endpoint Security Solutions: Deploy endpoint security solutions (e.g., EDR - Endpoint Detection and Response) that can monitor and control network interfaces. Some solutions can detect and prevent the bridging of wired and wireless connections.
- Group Policy Objects (GPOs) / Mobile Device Management (MDM): For Windows environments, GPOs can be used to disable or restrict the ability to create Soft APs. MDM solutions can enforce similar policies on mobile devices.
- Network Monitoring: Monitor network traffic for unusual bridging activities or connections originating from unexpected wireless interfaces on wired hosts.
- WIDS/WIPS: Can detect unauthorized wireless signals originating from devices that are physically inside the corporate network.
Detailed Explanation
Implementing strict corporate policies is essential to avoid the misuse of Soft AP features. Organizations should create guidelines that prohibit employees from activating Soft AP on devices connected to the corporate network. Additionally, deploying endpoint security solutions can help monitor devices for unauthorized behavior, while tools like Group Policy can restrict the ability to create Soft APs on managed devices. Continuous network monitoring generates alerts for unusual activities that could indicate a Soft AP is being used, and Wireless Intrusion Detection Systems can identify signals from unauthorized APs, enabling quicker responses to potential threats.
Examples & Analogies
Consider a high-security facility with strict rules about who can enter and under what circumstances. If someone could easily walk into the facility and override the security systems just by following these rules, it would become a target for breaches. However, by enforcing strict visitor protocols, installing security cameras, and constantly monitoring activity, the facility can protect itself from unauthorized access. Similarly, implementing strict rules and monitoring network traffic will help safeguard the corporate network from risks associated with Soft APs.
