As more businesses rely on wireless connectivity to power daily operations, the risks associated with unsecured networks grow. Cybercriminals are always on the lookout for vulnerabilities, especially during periods of high activity.

With Q4 around the corner—a time when businesses are often stretched thin managing increased traffic, sales, and operations—there’s a heightened risk of security breaches. Preparing your WiFi networks now is essential to protect sensitive data and keep your business running smoothly during this busy period.

1. Increased Targeting of Public Networks

As the holiday season approaches, business travel and remote working hit their peak. Employees on the move often rely on public WiFi networks to stay connected, whether they’re working from a café, airport, or hotel. While convenient, these public networks are notoriously insecure, making them a prime target for cybercriminals.

Public WiFi hotspots are especially vulnerable to man-in-the-middle (MITM) attacks, where hackers intercept communications between users and the network, gaining access to sensitive information like passwords, emails, and corporate data. The more remote workers connect to public WiFi without proper precautions, the higher the risk of a security breach.

Technical Recommendations:

Enforce the Use of Virtual Private Networks (VPNs): VPNs encrypt data traffic, creating a secure tunnel between the user’s device and the internet. This makes it significantly harder for attackers to intercept or tamper with data.
Implement Multi-Factor Authentication (MFA): MFA adds an extra layer of security by requiring users to provide two or more verification factors to access company resources, reducing the risk of unauthorised access.
Utilise Mobile Device Management (MDM) Solutions: MDM allows businesses to enforce security policies across all employee devices. It ensures that devices connecting to company resources comply with security standards, such as having updated antivirus software and strong passwords. MDM can also remotely lock or wipe devices that are lost or compromised.
Promote Secure WiFi Protocols: Encourage the use of secure WiFi networks that use strong encryption standards. Employees should avoid connecting to open or unsecured networks whenever possible.

2. Rogue Access Points

A rogue access point is an unauthorised wireless device that hackers use to infiltrate a network, often posing as a legitimate WiFi connection. Once an unsuspecting user connects, cybercriminals can intercept data, access sensitive information, or inject malware. Users might not realise they’ve connected to a malicious network, thinking it’s a trusted part of their business environment.

Cybercriminals typically set up these malicious access points in areas where employees or customers frequently connect to WiFi, such as busy offices, conferences, or public spaces. By mimicking the name of a legitimate network (a technique called SSID spoofing), these rogue points lure users in, giving attackers a direct line to private business communications and data.

Technical Recommendations:

Implement Network Monitoring Tools: Use systems that scan for unauthorised devices and alert IT teams to any suspicious activity on the network.
Deploy Wireless Intrusion Detection Systems (WIDS) and Wireless Intrusion Prevention Systems (WIPS): WIDS/WIPS actively monitor the wireless spectrum for unauthorised access points and can automatically take action to prevent rogue devices from connecting. They provide real-time detection and response to potential threats.
Establish Strong Access Control Measures: Ensure that only authorised users and devices can connect to the network. This can be achieved through device authentication protocols and by maintaining an updated list of approved devices.
Regular Security Audits: Conduct periodic checks to identify and eliminate rogue access points within or near the business premises.

3. Outdated Encryption Standards

Using outdated encryption protocols like WEP (Wired Equivalent Privacy) and early versions of WPA (WiFi Protected Access) can leave your network exposed to cyberattacks. These older encryption standards have known vulnerabilities that hackers can exploit to gain network access. With modern tools, even a moderately skilled attacker can breach WEP or WPA encryption in minutes.

Technical Recommendations:

Upgrade to WPA3 Encryption: WPA3 offers significant improvements in encryption and overall network security, including stronger encryption methods, better protection against brute-force attacks, and enhanced security for open networks.
Address Compatibility Issues: Recognise that not all devices support WPA3. As an interim solution, implement WPA2-Enterprise with strong authentication methods like IEEE 802.1X and EAP (Extensible Authentication Protocol). This provides robust security while maintaining compatibility with older devices.
Regularly Update Encryption Protocols: Stay informed about the latest security advancements and ensure that all network devices, such as routers and access points, are updated to support current encryption standards.
Plan for Gradual Migration: Develop a phased approach to upgrading your network infrastructure to support WPA3, including budgeting for new hardware if necessary.

4. Phishing Attacks Over WiFi Networks

Phishing attacks can also be carried out via WiFi networks. One common method is through rogue websites or fake login screens that mimic legitimate business portals.

When employees connect to a compromised WiFi network, they may be redirected to these fake websites, where they’re prompted to enter login credentials. Once attackers have these details, they can gain unauthorised access to sensitive information.

For example, a cybercriminal may set up a rogue access point with a name similar to the business’s official network. Employees who connect to it may be shown a fraudulent login page asking for their company credentials.

Technical Recommendations:

Employee Training: Educate staff about recognising phishing attempts, such as double-checking website URLs and being wary of unexpected login requests.
Enforce the Use of MFA: Multi-factor authentication can prevent unauthorised access even if credentials are compromised.
Use Secure Web Gateways or DNS Filtering: Implement tools that block access to known phishing sites and malicious domains. These solutions can prevent users from accessing harmful websites, even if they inadvertently connect to a compromised network.
Encourage the Use of Trusted Networks: Advise employees to connect only to verified WiFi networks and use VPNs when accessing company resources.

5. Weak Passwords and Network Access Control

Weak passwords are one of the most common vulnerabilities in WiFi networks, making them easy targets for brute-force attacks. Hackers use automated tools to rapidly guess passwords until they gain access, and weak or commonly used passwords provide little resistance. Once inside, attackers can potentially gain access to sensitive business information, causing significant damage to a company’s operations and reputation.

Technical Recommendations:

Enforce Strong Password Policies: Require the use of complex passwords that include a combination of uppercase and lowercase letters, numbers, and symbols. Passwords should be at least 12 characters long and avoid common words or patterns.
Regularly Update Passwords: Implement policies that require passwords to be changed periodically and prevent the reuse of old passwords.
Implement Multi-Factor Authentication (MFA): Adding an extra layer of security beyond passwords makes unauthorised access more difficult.
Introduce Enterprise-Level Authentication Methods:
IEEE 802.1X Authentication: Use this standard for network access control, which provides port-based access control and is commonly used in enterprise networks.
RADIUS Servers: Implement Remote Authentication Dial-In User Service (RADIUS) servers to manage authentication, authorisation, and accounting for network access. This centralised approach enhances security and simplifies user management.
Network Segmentation: Divide the network into smaller, isolated segments. For example, separate guest WiFi from the internal business network to prevent attackers from moving laterally if one segment is compromised.
Access Control Lists (ACLs): Use ACLs to define which users or devices have access to specific network resources, reducing the potential attack surface.
