# Wireless Network Security Testing Service **URL:** https://securesys.com.tr/en/services/wireless-network-security-test-service ### What Is Wireless Network Security Testing? Wireless technology (Wi-Fi) has become one of the most critical communication layers in an organisation's digital operations. Mobile access for staff, guest networks, IoT devices, production systems, wireless barcode terminals, IP telephones and smart building systems all communicate directly over wireless networks. That ubiquity makes wireless one of the most valuable targets an attacker can find. Firewalls, intrusion detection and prevention systems (IDS/IPS), endpoint protection (EDR/XDR) and network segmentation all protect the corporate infrastructure — yet a single configuration error on the wireless network can render those layers substantially ineffective. Wireless network security testing (wireless penetration testing) is a professional penetration testing service that assesses your Wi-Fi infrastructure from a genuine attacker's perspective. Testing covers more than the access points: access control mechanisms, the authentication infrastructure, wireless clients, guest networks, VLAN design, RADIUS servers, the certificate infrastructure and the wireless protocols themselves are all examined in detail. The purpose is not simply to run a vulnerability scan. Techniques a real attacker would use are applied in a controlled environment to measure how well the wireless infrastructure stands up to unauthorised access, data leakage, credential theft, network intrusion and privilege escalation. SecureSys wireless network security tests are planned and executed in line with internationally accepted [methodology](/en/learning/penetration-testing/penetration-testing-process-and-methodology). Our work is based on PTES (Penetration Testing Execution Standard), the OWASP Testing Guide, NIST SP 800-115, NIST SP 800-153, MITRE ATT&CK and industry best practice. Findings are reported not only with their technical detail but with their business impact, risk level and actionable remediation guidance. Wireless security matters strategically not just to IT teams but to business continuity, operational safety and the protection of information assets. As hybrid working has spread, IoT devices have multiplied and production systems have come to depend on wireless communication, wireless penetration testing has become an activity many organisations need to run on a regular schedule. ### Why Is Wireless Security So Critical? When corporate network security comes up, the components that come to mind first are usually firewalls, antivirus software, endpoint protection or email security. Seen from an attacker's perspective, however, wireless networks are frequently the first attack surface of choice for reaching the corporate network. The reason is simple: wireless communication happens through the air rather than over physical cable, and signals broadcast over radio frequencies are reachable from a distance. An attacker does not need to enter the building — the wireless network can be analysed from the car park, a neighbouring building, a shared area or anywhere near the campus. A misconfigured wireless network can neutralise even a strongly protected internal architecture. Insufficient segmentation between the guest and corporate networks, weak password policy, legacy encryption protocols or gaps in client validation all allow an attacker to gain unauthorised access to the corporate network. A successful attack through the wireless network can lead to: - Unauthorised access to the corporate network. - Theft of user credentials. - Lateral movement to critical systems on the network. - Access to file servers, the Active Directory infrastructure or database systems. - Sensitive data being moved outside the organisation. - Service outages affecting business continuity. - Malware or ransomware spreading across the network. Wireless infrastructures still running WPA2-PSK, operating on default configuration, or never assessed in years carry particularly high risk against modern attack techniques. The rapid growth in IoT devices, wireless printers, IP telephones, production terminals and mobile devices that comes with digital transformation widens the wireless attack surface further. Every new device becomes a potential entry point if it is not configured correctly. Wireless security cannot therefore rest on a strong password alone. It must be supported by access control, network segmentation, certificate-based authentication, central management policy and regular penetration testing. #### Wi-Fi Technologies and Wireless Standards Wireless technology continues to evolve, and each generation offers different security mechanisms. SecureSys testing assesses the standards and protocols in use to establish the current security level. **Wireless standards supported** - IEEE 802.11a - IEEE 802.11b - IEEE 802.11g - IEEE 802.11n (Wi-Fi 4) - IEEE 802.11ac (Wi-Fi 5) - IEEE 802.11ax (Wi-Fi 6) - IEEE 802.11be (Wi-Fi 7) - 2.4 GHz networks - 5 GHz networks - 6 GHz networks (Wi-Fi 6E) ### Which Organisations Should Have Wireless Security Testing? Any organisation running a wireless network should have it tested regularly. This applies particularly to: - Banks - Public sector institutions - Universities - Hospitals - Defence industry - Holding companies - Shopping centres - Hotels - Factories - Logistics companies - Energy companies - Retail chains - Airports - Data centres ### What Are the Objectives of Wireless Security Testing? The core objectives of a professional wireless penetration test are to: - Assess the security posture of the wireless access points - Test the security of the authentication mechanisms - Analyse the encryption algorithms in use - Identify opportunities for unauthorised access - Detect rogue access points - Measure resilience to client-side wireless attacks - Verify whether the guest network can reach the corporate network - Assess the effectiveness of wireless segmentation - Verify the network access controls - Analyse conformity of the wireless infrastructure with international standards The result covers not only the vulnerabilities that exist today but the risks that could emerge, together with remediation guidance. ### Why Are Wireless Networks Among an Attacker's First Targets? Organisations invest heavily in firewalls, EDR, IPS and SIEM, yet wireless is frequently the attack surface that gets overlooked. Without ever entering the building, an attacker can listen to the wireless signal and launch an attack from: - The car park - A neighbouring building - The cafeteria - The visitor area - The perimeter of the factory The following conditions create particular risk: - Default access point configuration - Weak Wi-Fi passwords - Legacy WPA/WPA2 protocols - Incorrect VLAN separation - Rogue access points - Evil twin attacks - Misconfigured guest networks - 802.1X configuration errors - RADIUS server weaknesses - Gaps in certificate validation Weaknesses of this kind lead to data breaches and unauthorised access affecting not just the wireless network but the organisation as a whole. ### Can Active Directory Be Compromised Through the Wireless Network? Many organisations treat the wireless network as a standalone infrastructure that only provides internet access. In reality, a misconfigured Wi-Fi network can be the first step in an attack chain that reaches all the way into Active Directory. A professional penetration test does not assess wireless purely on password strength. Network segmentation, user authentication, VLAN configuration, [NAC solutions](/en/services/nac-solutions), the RADIUS infrastructure and client isolation are analysed together — and from that, how far an attacker could progress inside the network. In a plausible scenario, an attacker who gains unauthorised access to the wireless network can reach the corporate internal network if segmentation is inadequate. From there they can begin reconnaissance against file servers, domain controllers, databases or critical application servers. Misconfigured access policy, weak authentication or gaps in privileged account management can allow the attack to progress as far as the domain. Wireless security therefore extends well beyond having a strong Wi-Fi password. The effectiveness of the controls between the wireless infrastructure and the corporate network, the quality of the segmentation and the correctness of the access policy all matter just as much. SecureSys wireless security testing evaluates the attack chains that could begin on the wireless network under controlled conditions, and reports the lateral movement risk we find. #### WPA2 and WPA3 Security Testing Wireless security rests on the encryption and authentication mechanisms in use. WPA2 and WPA3 are the most widely deployed Wi-Fi security protocols today, but misconfiguration, weak password policy or legacy client devices can lower the security level substantially. SecureSys wireless security testing performs the following checks. **WPA2 security** - WPA2-PSK configuration - WPA2-Enterprise analysis - Password strength - Handshake analysis - Offline password attack scenarios - PMKID analysis **WPA3 security** - SAE (Simultaneous Authentication of Equals) - WPA3-Personal - WPA3-Enterprise - Protected Management Frames (PMF) - Transition mode security - Authentication analysis #### WEP Security Risks WEP (Wired Equivalent Privacy) is a legacy wireless encryption protocol no longer considered secure. On a network still using WEP, attacks such as: - Password cracking - Packet analysis - Network access - Traffic interception can be carried out within a very short time. SecureSys testing identifies systems still using WEP and recommends migration to modern standards. #### Enterprise Wi-Fi (802.1X) Security 802.1X infrastructures providing central authentication with a username and password are widely used on corporate wireless networks. SecureSys performs the following checks. - IEEE 802.1X - Enterprise authentication - RADIUS configuration - Active Directory integration - Microsoft Entra ID integration - Network Access Control (NAC) - EAP configuration #### RADIUS and EAP Authentication Security RADIUS servers and the Extensible Authentication Protocol (EAP) provide user authentication in an enterprise Wi-Fi infrastructure. The principal mechanisms tested: - PEAP - EAP-TLS - EAP-TTLS - EAP-FAST - MSCHAPv2 - Certificate validation - RADIUS server configuration - User authentication policy #### Rogue Access Point Detection A rogue access point is one connected to the corporate network without authorisation, often set up by employees themselves. These devices can: - Weaken network security - Enable unauthorised access - Cause data leakage - Bypass network segmentation SecureSys testing surveys the environment to identify access points that do not belong to the corporate inventory. #### Evil Twin Attacks In an evil twin attack the adversary stands up a fraudulent access point using the same network name (SSID) as the organisation's own. When users connect to it without realising, the attacker can capture: - Usernames and passwords - Corporate session data - VPN credentials - Web traffic SecureSys uses controlled evil twin scenarios to assess how well users and infrastructure resist this class of attack. #### Captive Portal Security The captive portal systems used on guest networks are also assessed. Areas tested: - Authentication - Session management - Cookie security - HTTPS usage - Authorisation controls - Bypass scenarios - User isolation #### Man-in-the-Middle (MITM) on Wireless Networks Wireless networks are among the riskiest environments for man-in-the-middle attacks. SecureSys evaluates the following techniques under controlled conditions. - ARP spoofing - DNS spoofing - Evil twin - SSL strip - DHCP manipulation - Proxy-based MITM - Traffic redirection The aim is to verify whether user traffic on the network can be intercepted, and how effective the existing controls are. #### Wi-Fi Encryption and Authentication Mechanisms The encryption algorithms and authentication methods used on the wireless network are analysed in detail. The principal technologies examined: - WEP - WPA - WPA2 - WPA3 - AES - TKIP - PMKID - SAE - PSK - Enterprise authentication - Protected Management Frames (PMF) #### Wireless Segmentation and Guest Networks On a corporate wireless network, the employee network, the guest network and the IoT network should be kept apart. Segmentation analysis performs the following checks: - Guest network - Corporate network - IoT network - VLAN design - Network isolation - Client isolation - Firewall rules - Network transition policy A misconfigured guest network can allow an attacker to reach corporate systems. #### IoT and Wireless Device Security IoT devices connected to the wireless network frequently have limited security features. Devices tested: - IP cameras - Printers - Smart televisions - Smart sensors - Smart lock systems - Industrial IoT devices - POS terminals - Handheld terminals Security areas analysed: - Default passwords - Firmware security - Exposed services - Unauthorised access - Network isolation - Patch level #### How the Wireless Security Testing Process Works **\1. [Scoping](/en/learning/penetration-testing/how-to-define-penetration-test-scope) and planning** Before testing begins we agree the scope of the wireless infrastructure with the organisation. The access points, wireless controllers, guest networks, SSIDs, locations and test scenarios to be included are all clarified. Timing is planned so business continuity is unaffected, and the authorisation process is completed. **\2. Wireless discovery and passive analysis** The first stage analyses broadcasting access points, SSIDs, channels, signal levels and the wireless topology. Broadcast configuration, encryption methods and visible network components are assessed to establish the attack surface. **\3. Assessment of security controls** The wireless security architecture is examined in detail. Authentication methods, WPA2/WPA3 configuration, the 802.1X infrastructure, RADIUS servers, guest networks, VLAN separation, access policy and access point security settings are all assessed to identify misconfiguration. **\4. Controlled penetration testing** Within the agreed scope, controlled security verification is carried out in a way that will not disturb the production environment. The aim is to confirm whether the weaknesses identified represent genuine risk, and to assess the effectiveness of unauthorised access controls, network segmentation, client isolation and the wireless security controls. **\5. Risk analysis and technical reporting** Findings are classified by severity and reported in detail. Each finding is presented with technical explanation, likely business impact, risk level, evidence and actionable remediation guidance. A summary assessment is also prepared for management to support decision-making. **\6. Remediation and verification (retest)** Once the organisation has made its improvements, verification testing is carried out on request. This re-assesses the effectiveness of the measures applied and confirms that the critical risks have been addressed. #### Why SecureSys? Wireless security is not an analysis you run with tools. An effective wireless penetration test requires experienced specialists, international methodology and a technical approach grounded in real attack scenarios. Our wireless security testing identifies not only the vulnerabilities that exist but the risk they create for your organisation, and delivers remediation guidance you can act on. **TSE-certified competence** Wireless security tests are performed by penetration testers qualified under the TSE TS 13638 standard, in line with internationally accepted methodology. **International testing methodologies** Our testing is planned and executed in line with internationally accepted standards including PTES (Penetration Testing Execution Standard), NIST SP 800-115, NIST SP 800-153, the OWASP Testing Guide and MITRE ATT&CK. **Real attack scenarios** We go beyond automated [vulnerability scanning](/en/services/cyber-security-software) to assess your wireless infrastructure from a genuine attacker's perspective. Misconfiguration, access controls, network segmentation and authentication mechanisms are analysed through controlled testing. **Technical and executive reporting** At the end of the test we produce a detailed findings report for technical teams and an executive report summarising the business impact of the risks and the priority actions — giving both engineers and decision-makers a roadmap they can act on. **Risk-driven approach** Every finding is prioritised not only on technical grounds but against business continuity, data security, operational impact and regulatory compliance. **Remediation and verification support** Technical advice is available after reporting while the vulnerabilities are being addressed. On request, the fixes are re-assessed through verification testing so the effectiveness of the measures taken can be confirmed.
