Improving Wi-Fi Security

Tips & Best Practices for Improving Wi-Fi Security

Hide the Wi-Fi Network

Routers and access points don’t have to broadcast the SSID. If you block your router from sending out its identifier the Wi-Fi becomes a hidden network. Those devices that already have connection data stored will still be able to connect, but passers-by won’t see it. Without knowing the name of the network, it is impossible to connect to it.

Update Firmware

Routers and access points run software called firmware which essentially controls everything they do. It sets the security standards for your Wi-Fi network and defines the rules about which devices can connect, and so on. Keeping firmware up to date means you’ve got the latest bug fixes and security patches and are protected against whatever exploits have just been discovered.


VLANs serve as a useful tool for providing security to Wi-Fi clients by isolating traffic from the different users based on which SSID they connect to. This kind of setup is very common when you want to have a guest network which is completely separate from the company’s private network.

As hackers get smarter, the need to protect your digital assets and network devices is even greater.

What is the need for IT security?

While providing IT security can be expensive, a significant breach costs an business far more. Large breaches can threaten the health of a business. During or after an incident, IT security teams can follow an incident response plan as a risk management tool to gain control of the situation.

What is the difference between IT security and information security

Although IT security and information security sound similar, they do refer to different types of security. Information security refers to the processes and tools designed to protect sensitive business information from invasion, whereas IT security refers to securing digital data, through computer network security.

What are the threats to IT security?

Threats to IT security can come in different forms. A common threat is malware, or malicious software, which may come in different variations to infect network devices, including: Ransomware, Spyware and Viruses. These threats make it even more important to have reliable security practices in place.

How do I benefit from IT security?

IT security prevents malicious threats and potential security breaches that can have a huge impact on your business. When you enter your internal company network, IT security helps ensure only authorised users can access and make changes to sensitive information that resides there. IT security works to ensure the confidentiality of your business data.

You depend on email as a necessary form of communication. But is your email really secure? Here’s how to protect your business email privacy:

1. Encrypt email and server connections

If you send email without ensuring it’s encrypted, it can be intercepted and read by hackers. It’s important to employ email encryption software and to also make sure the connection between servers is encrypted as well, using Transport Layer Security.

2. Verify Emails

It’s critical to know that the person who sent the email is indeed the person to whom the email is attributed, and it’s vital to know the data in the email hasn’t been altered along the way. Configure software to digitally sign an encrypted document.

3. Educate Staff

The best security technology in the world can’t mitigate one of the primary sources of risk for your business: human curiosity. It’s not just a matter of securing outgoing email; your company’s data can be at risk with incoming mail as well. Not only is there a rise in malicious spam, there’s an evolution in email delivery methods.

4. Software Updates

Businesses usually set up email and leave it. Stay on top of the email server software, understanding vulnerabilities and religiously installing updates and patches is critical.

5. Scanning Email Content

Employ software to filter for content such as inappropriate language and images, both incoming to provide a professional work environment and outgoing to protect your company’s reputation.

6. Check out your Partner

Businesses generally use a third party for email security. Get references from people you know and trust.

For most businesses, simply taking the time to question and to evaluate email security is a big leap in the right direction. A lot of these systems get rolled out without thinking about security, and people just keep using them. A lot of people don’t seem to understand that email is almost by nature not secure.
