Wireless Security: Why You Need to Take It Seriously In 2018

When waves of cyber attacks hit last year, such as WannaCry and Not Petya ransomwares, businesses lost billions of dollars in high-profile breaches. In addition, more than half of the U.S. population’s Social Security information was compromised in the Equifax breach. It was a record-breaking year.

Perhaps the only good that came out of these fiascos is that users became more aware of the importance of cyber security. But it is no longer sufficient to only care about wired network security. Organizations and businesses also have to pay attention to other aspects of security, such as physical security and wireless security.

In line with multiple cyber security forecasts, such as our 8 Cyber Security Predictions for 2018, organizations need to watch out for more sophisticated attacks in 2018. According to the Wi-Fi Alliance, more than 9 billion wireless devices will be used in 2018. Gartner forecasts connected devices to rise from 11 billion in 2018 to over 20 billion by 2020. With the proliferation of wireless-enabled and IoT devices, wireless network security is vital.

However, not all wireless security solutions are equal. Last year, for example, many dealt with KRACK (Key Reinstallation Attack), which leveraged a WPA2 vulnerability that could lead to man-in-the-middle attacks. While many wireless vendors suffered this vulnerability, SonicWall wireless access points were not vulnerable.

How do I choose a wireless security solution?

It can be easy to get drawn in by sales pitches that show you pretty dashboards, features that you don’t need or seldom use, or super-expensive gear that you pay a premium for just because of the brand name.

Instead, take a step back and think of what you really should care about: a Wi-Fi connection that actually works with unfaltering security. Make sure you are committing yourself to a vendor that takes security, user experience and reliability very seriously.

How can I make my Wi-Fi secure?

Organizations, small- and medium-sized businesses (SMB) and individual users can implement cyber security best practices to drastically reduce Wi-Fi vulnerabilities.

  • First and foremost, make sure that you are not broadcasting an open SSID (how others see and connect to your wireless network)
  • Adjust the transmit power on your access points to serve just the area of coverage that is required
  • For corporate networks, separate guest users from internal users
  • Turn on rogue detection and ensure that firewall settings, such as DPI-SSL/TLS are enabled on your network
  • To further improve security, add a firewall to your network

Wireless is an overlay to your wired network. Adding a firewall with an integrated wireless controller capability to your network will further enhance the security of your entire network. The benefits of adding such a firewall include:

  • Complete management of wireless and wired infrastructure
  • Granular application identification, control and visualization
  • Discover and block advanced threats and vulnerabilities
  • Improved security posture and performance that scale to your business requirements

Though there are many wireless security features that can enhance your wireless security, some are more critical than others. Basic functionalities like Wireless Intrusion Detection System (WIDS) and Wireless Intrusion Prevention System (WIPS) must be supported across wired and wireless infrastructure.

Others cyber security capabilities, like application control, content filtering and deep-packet inspection (DPI) even over encrypted traffic, are all essential.

Adding multi-layered security protection to your overall network infrastructure will help minimize network breach success. In order to support the next-generation mobile workforce, BYOD and ability to implement wireless guest services is significant. Site tools can be used to survey wireless signals to optimize the required area of coverage.

These wireless security capabilities, coupled with single-pane-of-glass management, makes it effective and efficient for network admins to have visibility into the network and detect threats on a real-time basis.
