An Overview Of Rogue Access Points In Cybersecurity
By Tom Seest
In cybersecurity, a rogue access point is an unauthorized wireless network device that connects to a company’s network. This device can be used for information theft and physical harm.
There are multiple methods to prevent rogue access points from invading your network. These include staff education, intrusion detection, and prevention systems, as well as other measures.

Rogue access points (APs) are wireless devices that are unauthorized to connect to a network. This poses an extensive security risk, as rogue APs could be exploited by malicious actors to gain access to networks and steal data.
Rogue access points are often created by employees who want to use their own devices on the business network but don’t understand the security repercussions. They could be tech-savvy individuals looking for ways to circumvent authentication controls or other security measures on their personal devices or disgruntled workers who feel trapped by their employer’s network and decide to set up their own wireless access point for personal use.
Rogue access points pose a security risk to any organization that relies on wireless technology. They have the potential to breach network security, collect user data, or even steal sensitive information.
The good news is that rogue access points are much easier to detect and eliminate than they used to be. In fact, Microsoft Digital recently completed an extensive project to locate and eliminate malicious access points from their networks.
Microsoft engineers reported that uncovering malicious access points was a complex challenge that required the company to use various data tools. They were eventually able to correlate information and identify thousands of potentially harmful devices on their network.
Once they were able to identify which devices were malicious, the team needed to shut down their ports. Though this caused some collateral damage, it proved the simplest solution and helped eliminate many of these devices from their network.
Another crucial step in detecting rogue access points is running periodic scans. PCI DSS requires that each company perform quarterly scans, but you may opt for more frequent inspections if desired.
A malicious access point can circumvent network security measures by employing techniques like MAC spoofing and roaming to other legitimate APs/channels. Furthermore, they have the capacity to capture users’ internet traffic and alter it, such as adding data to an attacker’s database or redirecting their online banking transactions.
A malicious access point can also steal data from a network by monitoring DNS requests and other types of Internet traffic, giving the attacker a profile of how users use the Internet. They could then send these changes to an intended endpoint. For instance, if they intercept a bank’s website login page and use it to alter account balances or deposit money into their own account, that could result in financial loss for the user.

Rogue access points can be exploited by malicious actors to gain access to your network. Depending on the type and how it’s installed, this could result in a variety of issues, such as unauthorized entry, data leakage, and even denial-of-service attacks.
NetStumbler and other wireless scanning tools can assist in detecting a rogue access point. Furthermore, these programs enable you to determine whether or not the access point is connected to your network.
If you suspect a rogue access point, further investigation should be conducted by running a network security scanner such as an IDS/IPS to pinpoint its location and whether or not it’s being used. You could also take a laptop connected to your network and measure the signal strength from the rogue access point to pinpoint its exact location.
Consider implementing a comprehensive Zero Trust strategy. Doing so will reduce the number of malicious access points in your network and discourage potential users from trying to install them.
Rogue Detection and Mitigation
The Cisco WLC offers various rogue detection techniques to help mitigate the threat posed by a malicious application (AP). These include a rogue detector, auto containment, switch port trace, and RLDP (Real-Time Data Porting).
RPID (Radio Probe Response and Beacons): When a malicious device sends probe responses or beacons, that information is passed to the controller for processing. If a positive match is found on the closest switch, containment procedures can be initiated against the intruder.
If no match is found, containment proceeds to neighbor switch up to two hops away (by default). The rogue then needs to be contained by one or more managed APTs working together in concert to temporarily mitigate the threat.
Containment is a technique that uses over-the-air packets to interrupt service on an unauthorized access point until physical removal can take place. This approach may be employed as a temporary stopgap measure, or it could also be employed permanently to enforce authorized usage policies by disallowing unauthorized stations from ever associating with rogue APs.

Rogue access points are a type of cybersecurity risk that allows hackers to circumvent network protection. They often appear as legitimate wireless networks in public places where users are unaware they’re connecting to an untrusted connection.
These malicious access points can be exploited to steal data from your organization and give hackers access to sensitive information, such as login credentials.
One way to detect rogue access points is by scanning them with either a wireless scanning tool or a dedicated rogue access point detection system. While these tools may be costly, they are an essential element of any robust security strategy.
Another way to detect rogue access points is by monitoring their internet connections. This will give you a good indication of their location and what’s going on.
If you uncover a malicious access point connecting to your company’s network, it is imperative that you investigate further and contact your IT team. These rogue access points may have been installed through social engineering techniques or internal sources.
Detecting rogue access points can be done by comparing their MAC address to that of your network. Unfortunately, this method may not always be successful and could miss any rogue points on the same network as well as those inaccessible or blocked by other devices.
Without an IT team dedicated to this task, it may be difficult to detect a rogue access point. Thus, creating the proper security policies and providing training for your staff members is essential. These procedures guarantee that employees are informed of all cyber security threats and know what signs to watch out for.
Additionally, having a no-exceptions policy is beneficial; this ensures no rogue access points are installed by employees or external sources unaffiliated with your IT department. Doing this helps safeguard your most sensitive data against both internal and external threats.

Rogue access points (RAPs) are unauthorized wireless devices that can connect to a network without permission. They could also be created by hackers in order to launch attacks against the company’s infrastructure or steal data from it; this poses particular risks for businesses storing sensitive information on their networks.
Businesses must ensure that their network security is as tight as possible, monitoring access to systems and ensuring only authorized users can connect to the network. It may also be beneficial to use software or tools tailored specifically towards cyber security tasks.
However, people can still create rogue access points and connect their devices to them. These access points tend to appear in public areas such as coffee shops or libraries with free Wi-Fi available, where people have the ability to create fake access points.
Some rogue access points are set up by employees who wish to connect their devices to a company’s network. For instance, if an employee is dissatisfied with the speed of the corporate wireless network, they could install their own private access point and plug it into their workstation or into the company LAN (local area network).
These malicious access points can be quickly detected and identified with wireless scanners or IDS/IPS tools. Furthermore, their signals can be monitored to identify their strength.
Another method for detecting a malicious access point is by inspecting its service set identifier (SSID). Hackers often use this SSID to make themselves appear as legitimate networks, thus leading connected devices to connect to the fake access point instead of their authentic one.
Once this occurs, the fake network becomes active and can be used to intercept and spoof communication between connected devices. This gives attackers the ability to capture usernames, passwords, and other sensitive information.
A malicious access point can also be set up to disrupt a network’s operation by acting as Man-in-the-Middle (MITM). Here, hackers relay Clear to Send (CTS) frames that prevent other connected devices from communicating, leading to their disconnection from the mainframe.
