Follow These Steps to Secure Your Wireless Networks

By CIOReview | Friday, August 26, 2016

Wireless technology has evolved into an advanced platform that has elevated the convenience level for enterprises across the globe. With innovation in wireless networking, vulnerabilities have also made their way into the wireless technology arena. In that regard, administering a set of security techniques can help the enterprises build an effective shield to safeguard their wireless network against unauthorized access.

Unlike wired networks, wireless networks can be interrupted or hacked from any point of connectivity. Although implementing traditional security measures such as restricting the IP addresses or filtering MAC addresses may help to a certain extent, enterprises today need a lot more sophisticated and rigid techniques.

Listed below are some of the security techniques that enterprises can implement to secure their wireless networks:

Enable WPA2 Security Encryption

Although there are encryption techniques such as WPA, AES and TKIP, it is always recommended to implement the WPA2 security supported by Remote Authentication Dial-In User Service (RADIUS) protocol.

Know What’s Latest in Wireless Security Standards

To adopt a systematic approach towards achieving a highly secure wireless network, understanding the various aspects of the latest 802.11 IEEE standards is crucial. The standards are classified with respect to its vivid range of functions and as per the requirements of the users.

Update the Network Credentials Regularly

Frequently changing the password and name of an enterprise’s wireless network happens to be the most simple as well as effective technique. This step stages a primary level of security, building a shield to tackle a potential hacker trying to break into the enterprise network.

Generate a Policy to Handle Guest Access

Enterprises always tend to deal with a situation where they need to grant access to the guests visiting their premises. This scenario invites the risk of hackers trying to bypass the company’s network using advanced software and tools. Incorporating a systematic process that enables secure access for guests without exposing confidential enterprise data is always a recommended course of action.

Monitor Mobile Devices

From the past few years, smartphones have played an integral part in the usage of wireless networks that have resulted in unintended security threats. But, even in enterprises, imposing rules that focus on restricting the use of mobile devices always seems to be unprofessional. Instead, keeping a record of the data in the mobile devices is always a better idea for securing the valuable enterprise data.

Detect all Rogue IPs in the Network

Employees in an enterprise may use unauthorized access points or routers inadvertently to access the company’s wireless network. Potential attackers may take advantage of this opportunity to gain access to the plethora of enterprise data with little or no effort. It is thus vital to secure the enterprise networks by monitoring the vulnerable access points thoroughly on a regular basis.

Impose a Priority-based Network Usage Policy

Limiting the bandwidth usage is another way of having a complete control over a company’s wireless network. To restrict the use of excess bandwidth, enterprises should be able to deploy firewalls and other forms of configuration management techniques on routers and allow employees to operate only on business critical applications.

Frequently Update the Network Configuration

When new devices are added to the network, most organizations tend to ignore the process of updating their existing network configuration and access control procedures on routers. Identifying and registering them accordingly with respect to the changes always keeps the network secured. An ideal network management practice involves the task of scanning the network logs regularly. Consistent network monitoring will help companies to identify critical vulnerabilities that may affect network performance.

In a constant quest to achieve optimum performance in enterprise operations, organizations are trying to deploy wireless technologies for seamless communication and collaboration. To that end, they should also be aware of the latest wireless security components available in the market.
