Design/Procuremen Phase
Keep Track of Wi-Fi Development Standards
Since the 802.11 popular changed into first introduced, enhancements have continuously been made to strengthen records rates, signal range, and security of wireless networks. Therefore, it is a superb idea to maintain song of the development of latest requirements as they appear, mainly while procuring new gadget or acquiring new wireless network services. In any new purchase, safety with the aid of one of the more potent wi-fi protection protocols which include WPA/AES or WPA2/AES should be taken into consideration, but by no means have to such wi-fi protection protocols be solely relied upon to guard information confidentiality and integrity, as new weaknesses in protocols may be discovered within the future.network deployments
Perform Security Risk Assessments and Audits to Identify Security Vulnerabilities
Security checks and audits are critical manner for checking the safety fame of a wi-fi network and figuring out any corrective action essential to keep an acceptable stage of safety. These exams can help perceive loopholes inside the wireless network, which include poorly configured get entry to points using default or without problems guessed passwords and SNMP network strings, or the presence or absence of encryption. However, a security risk evaluation can most effective provide a image of the dangers to information systems at a given time. As a result, it's miles crucial to perform checks and audits frequently once the wi-fi network is up and running.
Perform Site Surveys
Due to the character of radio frequency (RF) propagation, radio signal emissions can not generally be contained within a specific constructing or location. Excessive insurance through the wi-fi signal could pose large danger to the organisation, starting it to parking lot attacks on the network. Therefore, it's far essential to have a terrific expertise of the coverage requirements for the favored wireless network during the network-planning phase. By performing a site survey, one can become aware of:
the suitable technologies to apply;
barriers to avoid, eliminate, or work around;
insurance patterns to adopt; and
quantity of capability needed.
Apply a Defence-in-Depth Approach
The idea of "defence-in-depth" has been extensively employed within the secure design of stressed networks. The identical idea can also be implemented to wireless networks. By implementing more than one layers of security, the danger of intrusion through a wireless community is greatly reduced. If an attacker breaches one measure, extra measures and layers of safety remain in area to defend the network.
Separation of wireless and wired community segments, use of strong device and user authentication methods, software of network filtering based totally on addresses and protocols, and deployment of intrusion detection systems on the wi-fi and stressed networks are all possible measures that may be hired to build multiple layers of defence.
Separate Wireless Networks from Wired Networks
Due to the nature of wi-fi technology, wireless networks are relatively difficult to contain within a constructing and it's far commonly considered to be an un-relied on network. As a best practice, wi-fi networks and stressed out networks have to now not be immediately linked to every other. It is not unusual to set up firewalls to split and control the visitors between one-of-a-kind networks. For example, ARP broadcast packets must be blocked from entering a stressed out network from a wi-fi community considering the fact that a malicious person should uncover internal information, inclusive of Ethernet MAC address from those broadcasts.
Segment the Access Point's Coverage Areas
Due to the confined transmission potential of a wireless network, a malicious attacker can effortlessly release a Denial-of-Service (DoS) attack to carry down the network. Segmenting access point insurance regions can stability the hundreds on a wi-fi network and minimise any impact from DoS attacks.
