Wireless LAN Overview

This section provides an introduction to Wireless Local Area Networks (WLANs). This section contains the following subsections:

“What is a WLAN?” section on page 2

“How Does a WLAN Work?” section on page 2

After reading the Wireless LAN Overview section, you will be able to define the difference between a WLAN and a hard-wired LAN, obtain key design considerations for WLAN outdoor and indoor deployments, and learn the recent advancements in Wireless IPSec (WiFiSec) and WPA secure data transmission over traditional wireless deployments.

What is a WLAN?

A WLAN is a LAN that uses radio waves as the physical medium on which you are sending and receiving network data signals. In a conventional hard-wired LAN, client workstations are connected together with physical cables, such as shielded copper wire to fiber-optic cables. Hard-wired LANs are very expensive to implement due to the amount of effort required to install physical cabling. In addition to the high cost, you will face distance limitations depending on the type of cable you are using. Each type of physical cable has a length limitation or a maximum distance before the signal traveling on the wire deteriorates. In addition to high cost, cabling distance limitations, hard-wired LANs limit laptop client mobility, since you are leashed to your connection, to a modem, wall jack, or networking device, such as a hub, switch or routing device. Each time you want to move your laptop client from conference room to another conference room, you are required to disconnect and then reconnect once you have moved locations.

How Does a WLAN Work?

The standards used for WLAN communications are based on the Institute of Electrical and Electronic Engineers (IEEE) 802.11 series of standards. The IEEE 802.11 standards help to define and regulate the Physical and Media Access Control (MAC) layers of operation in a WLAN. For example, the IEEE 802.11b standard defines the use of the 2.4 Gigahertz (GHz) band in radio frequency (RF) for high-speed data communications, 802.11b supports data rates of 2 Mbps up to 11 Mbps. The IEEE 802.11g standard supports data rates up to 54 Mbps while also using the 2.4 GHz frequency band.

WLAN Design Considerations

Designing wireless networks opens up the door to an unbelievable array of connectivity options and benefits – anywhere from a shop owner wishing to provide free wireless Internet access to customers, to a large company wishing to free thousands of employees from their hard-wired workstations.

Unfortunately, the current state of wireless networking is far less secure than it needs to be, and improper installation of wireless networking equipment can lead to unforeseen security risks. The interim standard WPA is an interim solution that will be replaced.

SonicWALL security appliances provide a wide array of active and passive security features that can be enabled to deter attempts to gain unauthorized wireless access to your protected networks. The following is a top-ten checklist of SonicWALL-recommended deployment design considerations for your WLAN.

WLAN Design Top Ten Checklist

This section provides a top-ten checklist to securing your distributed wireless network with SonicWALL’s Secure Wireless Solutions.

Traditional ‘Wireless Security Tips’ lists recommend such actions as ‘Disabling SSID Broadcasts’, ‘Enabling MAC Filter’, and ‘Disabling DHCP Services’ for the sake of obscuring the wireless network. While this will likely minimize the chances wireless network trespassing, it will certainly make your wireless network more difficult to use for your authorized wireless users.

SonicWALL recommends better methods of network defense than security through obscurity, and goes to great efforts to ensure not only a secure network, but a secure network that is effortless and

uncomplicated to use. Although the three aforementioned tactics are possible with SonicWALL wireless equipment, SonicWALL instead recommends the following checklist for securing your wireless network:

1. Install a SonicWALL security appliance at your network gateway, and secure your network with Wireless IPSec (WiFiSec). Enabling WiFiSec causes the SonicWALL security appliance to pass only IPSec packets to and from its wireless interface. Enforcing WiFiSec ensures that wireless users are authenticated and that their wireless traffic is fully encrypted. Running SonicOS 2.5 Software and higher, WiFiSec is enabled by default to provide your network with end-to-end wireless traffic encryption using standard IPSec security mechanisms. This method of deployment ensures that only authorized users are connecting to the SonicWALL security appliance, and that the wireless traffic of authorized users is truly secure against interception and decoding from undesired third parties.

2. Install the SonicWALL Global VPN Client on your wireless clients.

Note This will require your Wireless clients to connect to the SonicWALL security appliance using the SonicWALL Global VPN Client for remote access to policy-allowed LAN resources, policy-allowed WAN access, and to other wireless clients.

Enable Gateway Anti-Virus (GAV), Intrusion Prevention Service (IPS), Content Filtering

(9)

3. As an alternative to (or even in conjunction with) the use of the SonicWALL Global VPN client, use WiFi (WPA Protected Access) in either the WPA-PSK or the WPA-EAP variety, both of which are supported by SonicWALL wireless products. WPA-PSK allows for the use of a pre-shared key or password for associating and authenticating with the wireless network, while WPA-EAP uses an extensible authentication protocol scheme, typically with a back-end user database such as RADIUS. Since WPA-EAP requires an external authentication server, it can be fairly complicated to configure, and is generally used infrequently by smaller networks. Also, using WPA requires that your wireless clients are WPA capable – this requires WPA compatible client cards (such as the SonicWALL Long-Range/Dual-Band wireless card) with current drivers, and a WPA supplicant or natively WPA-capable operating system.

4. Use the radio scheduling feature on your SonicWALL wireless equipment to disable the

wireless radios when they are not in use. If your wireless network is only in use from 7am to 10pm,

you can schedule the radio to disable itself entirely during off-hours, completely eliminating the possibility of unwanted or unauthorized detection or access without impeding regular use.

5. Enforce the use of Wireless Guest Services (WGS). By enabling this feature, all wireless clients

must authenticate themselves to the SonicWALL security appliance using HTTP or HTTPS before they are allowed access to resources on the WAN. The user and password database can either be stored onboard the SonicWALL security appliance or, the SonicWALL security appliance can authenticate users from external RADIUS servers. A recent online review of WGS said “Instead of having visitors and conference room attendees locked out of Wi-Fi goodness, [WGS] shunts them to a different place, the Internet.” Using WGS, network administrators can configure their SonicWALL security appliances to allow wireless guests access to the Internet, but with blocked access to your corporate network.

6. Activate the SonicWALL security appliance’s Wireless Intrusion Detection Services (IDS)

features. This will allow your SonicWALL security appliance to perform active and passive scans

of the 802.11b wireless channels to detect rogue access points, wireless access points that were installed on your internal network without your corporate IT network administrator’s approval. It also allows the SonicWALL security appliance to protect itself against association flood attacks and to detect possible disassociation attacks launched against your wireless clients using sequence number analysis.

7. If you are not using WiFiSec, WEP, or WPA use applications that can be directly secured, such as HTTPS Web browser sessions, SSH, or SSL-enabled applications like SFTP. Make sure these applications are password-secured, use strong passwords, and have their passwords changed often.

8. Select an SSID that is recognizable by your authorized users, but which does not disclose any

sensitive information.

9. Adjust the SonicWALL security appliance’s wireless radio power settings and management

frame settings. Tuning these settings properly can prevent your wireless signal from bleeding into

unwanted areas (such as public areas with adjacent buildings occupied by other wireless users). Wardrivers often look for public spots into which a usable signal has leaked, so take this into account when adjusting your SonicWALL security appliance.

10. Do not advertise your wireless network unnecessarily. When possible, place your wireless radios

away from the perimeters of your premises to avoid the radio signal bleeding beyond required boundaries. And finally, to reach the zenith of physical security for your wireless network, consider an elemental Faraday cage in a can: http://www.forcefieldwireless.com/products.html

Tip Document a clearly defined network security policy. This will help you ensure your users have the

information they need in order to connect using wireless clients. Make sure your users understand why these settings are required, and make sure that the security policy does not directly conflict with their network access needs.

Solution #1: Securing WLANs with SonicWALL Security Services

This section provides an introduction to SonicWALL Security Services that provide unified threat management against objectionable and inappropriate Web content, viruses, worms, Trojans, and malicious code for your wired and wireless networks.

This section contains the following subsections:

“SonicWALL Gateway Anti-Virus/Anti-Spyware/Intrusion Prevention Service” section on page 19

“SonicWALL Content Filtering Service” section on page 24

After reading the Deploying SonicWALL Security Services section, you will understand how these security services protect your network, how to activate the service on your SonicWALL security appliance, and how to enable the service to provide layered security for your WLAN.

SonicWALL Gateway Anti-Virus/Anti-Spyware/Intrusion Prevention Service

SonicWALL Gateway Anti-Virus (GAV), Anti-Spyware and Intrusion Prevention Service (IPS) is SonicWALL’s unified threat management solution that integrates gateway anti-virus, anti-spyware and intrusion prevention to deliver intelligent, real-time network security protection against sophisticated application layer and content-based attacks. Utilizing a configurable, high-performance deep packet inspection architecture, SonicWALL GAV, Anti-Spyware and IPS secures the network from the core to the perimeter against a comprehensive array of dynamic threats including viruses, spyware, worms, Trojans, and software vulnerabilities such as buffer overflows, as well as peer-to-peer and instant messenger applications, backdoor exploits, and other malicious code. Because new threats emerge daily and are often unpredictable, the deep packet inspection architecture is constantly updated to deliver the highest protection possible against an ever-changing threat landscape.

This unique solution features a powerful deep packet inspection engine that delivers threat protection directly on the security gateway by matching downloaded, e-mailed and compressed files against an extensive signature database created by a combination of SonicWALL’s SonicAlert Team and third-party sources. SonicWALL GAV, Anti-Spyware and IPS inspects over e-mail, Web, file transfer and a multitude of stream-based protocols as well as instant messaging and peer-to-peer applications, providing comprehensive network threat prevention and control. As an added layer of security, SonicWALL GAV, Anti-Spyware and IPS provides application layer attack protection not only against external threats, but also against those originating inside the network. Because files containing malicious code, viruses and worms can be compressed and therefore inaccessible to conventional solutions, SonicWALL GAV, Anti-Spyware and IPS integrates advanced decompression technology that automatically decompresses and scans files on a per packet basis. Supported compression formats include ZIP, Deflate and GZIP.

Unlike other threat management solutions, SonicWALL GAV, Anti-Spyware and IPS has the capacity to analyze files of any size in real-time without the need to add expensive hardware drives or extra memory. SonicWALL GAV, Anti-Spyware and IPS includes a pro-active alerting mechanism that notifies network administrators when a new threat is discovered. Granular policy tools and an intuitive user interface enable administrators to configure a custom set of detection or prevention policies tailored to their specific network environment. Available as a subscription-based security service for SonicWALL TZ and PRO Series security appliances, GAV, Anti-Spyware and IPS is a fundamental requirement for ultimate security protection and a key component of SonicWALL’s strategy of providing scalable, multi-layered security to networks of all sizes.

“Enabling SonicWALL GAV” section on page 23

“Enabling SonicWALL Anti-Spyware” section on page 24

Note When you activate SonicWALL IPS, SonicWALL GAV and Anti-Spyware are also activated. SonicWALL GAV/Anti-Spyware/IPS security services are managed directly from the SonicWALL security appliance.

SonicWALL IPS Protection for Your WLANs

SonicWALL IPS delivers a configurable, high performance Deep Packet Inspection engine for extended protection of key network services such as Web, e-mail, file transfer, Windows services, and DNS. SonicWALL IPS is designed to protect against application vulnerabilities as well as worms, Trojans, peer-to-peer, spyware, and back-door exploits.

The extensible signature language used in SonicWALL’s Deep Packet Inspection engine also provides proactive defense against newly discovered application and protocol vulnerabilities. SonicWALL IPS offloads the costly and time-consuming burden of maintaining and updating signatures for new hacker attacks through SonicWALL’s industry-leading Distributed Enforcement Architecture (DEA). Signature granularity allows SonicWALL IPS to detect and prevent attacks based on a global, attack group, or per-signature basis to provide maximum flexibility and control false positives.

Alternatively, SonicWALL Global Management System provides global management capabilities that enable administrators to manage SonicWALL IPS across multiple SonicWALL security appliances from a central location. SonicWALL GMS solutions allow administrators to create detailed reports based on attack source, destination and type of intrusion, such as “Top Intrusions,” “Destinations Over Time,” and “Intrusions Over Time.”

SonicWALL GAV Protection for Your WLANs

SonicWALL GAV delivers real-time virus protection directly on the SonicWALL security appliance by using SonicWALL’s IPS-Deep Packet Inspection v2.0 engine to inspect all traffic that traverses the SonicWALL gateway. Building on SonicWALL’s reassembly-free architecture, SonicWALL GAV inspects multiple application protocols, as well as generic TCP streams, and compressed traffic. Because SonicWALL GAV does not have to perform reassembly, there are no file-size limitations imposed by the scanning engine. Base64 decoding, ZIP, LHZ, and GZIP (LZ77) decompression are also performed on a single-pass, per-packet basis.

SonicWALL GAV delivers threat protection directly on the SonicWALL security appliance by matching downloaded or e-mailed files against an extensive and dynamically updated database of threat virus signatures. Virus attacks are caught and suppressed before they travel to desktops. New signatures are created and added to the database by a combination of SonicWALL’s SonicAlert Team, third-party virus analysts, open source developers and other sources.

(26)

SonicWALL GAV can be configured to protect against internal threats as well as those originating outside the network. It operates over a multitude of protocols including SMTP, POP3, IMAP, HTTP, FTP, NetBIOS, peer-to-peer, instant messenger applications, and dozens of other stream-based protocols, to provide administrators with comprehensive network threat prevention and control. Because files containing malicious code and viruses can also be compressed and therefore inaccessible to conventional anti-virus solutions, SonicWALL GAV integrates advanced decompression technology that

automatically decompresses and scans files on a per-packet basis.

SonicWALL Anti-Spyware Protection for Your WLANs

The SonicWALL Anti-Spyware Service protects networks from intrusive spyware by cutting off spyware installations and delivery at the gateway and denying previously installed spyware from communicating collected information outbound. SonicWALL Anti-Spyware works with other

anti-spyware programs, such as programs that remove existing spyware applications from hosts. You are encouraged to use or install host-based anti-spyware software as an added measure of defense against spyware.

SonicWALL Anti-Spyware analyzes inbound connections for the most common method of spyware delivery, ActiveX-based component installations. It also examines inbound setup executables and cabinet files crossing the gateway, and resets the connections that are streaming spyware setup files to the LAN. These file packages may be freeware bundled with adware, keyloggers, or other spyware. If spyware has been installed on a LAN workstation prior to the SonicWALL Anti-Spyware solution install, the service will examine outbound traffic for streams originating at spyware infected clients and reset those connections. For example, when spyware has been profiling a user's browsing habits and attempts to send the profile information home, the SonicWALL security appliance identifies that traffic and resets the connection.
