Five Ways To Keep Your Business’s Wireless Network Secured

Cyber security is an important issue for businesses large and small alike. You customer’s data and your data is very important and a breach can cause untold damage, especially if you have passwords and credit card numbers on your system. There have been a number of high profile breaches this year, including Evernote and Yahoo!;  no one is immune.

But while everyone’s waiting for “the Pearl Harbor of cyber attacks,” the attacks that your business should be concerned with might not be so overt. Corey Nachreiner, CISSP and Director of Security Strategy at WatchGuard, says businesses need to filter out the hype of the media and focus on the more likely and relevant threats that affect their network security on a day-to-day basis.

Smaller and mid-sized organizations, Nachreiner says, are bigger targets than they have been in the past.

Nachreiner was kind enough to send us a list of five ways you can best protect your business. Check it out:

1. Take a Multi-Layered Approach: Defense-in-Depth. When combined together, firewalls, intrusion prevention services, proactive anti-virus (AV) solutions, anti-spam and anti-phishing protection, and cloud-based reputation defenses maximize the chance that one or more security controls will catch part of an APT attack.

2. Filter egress rather than just ingress. Companies need to carefully monitor and restrict the flow of outbound information. If the data doesn’t match the organization’s security policies, the packets should not be allowed to be distributed.

3. Open your network’s eyes. Visibility helps organizations enforce acceptable use policies that are mandated by industry regulation, legal and political jurisdictions as well as corporate culture.

4. Segment by trust and security. Businesses need to set thoughtful, strategic governance and access policies to protect privileged information while allowing full access to other information.

5. Treat your wireless network the same as your wired network. More and more companies are incorporating bring-your-own-device (BYOD) policies in order to benefit from a mobile workforce and enhance productivity. With threats on the rise and growing amounts of corporate data stored on workers’ personal devices, it is more critical than ever that steps be taken to thoroughly secure wireless infrastructure.

We’ve covered network security a lot, because it’s such an important issue for business owners. See our archives for more tips on making your network as secure as it can be.
