One unfortunate byproduct of using the Internet on business computers and mobile devices is viruses and other security threats. According to Retail Online Integration, 71 percent of IT managers said programs like spyware and malware are serious concerns, and 88 percent are concerned about workers downloading or using unauthorized programs that can lead to viruses. That’s why having effective anti virus software and addressing security issues is so important for averting threats.

Here are four types of protection that can keep your business’s network safe.

1. Email

A major catalyst for viruses, malware, trojans, and adware is email attachments. A good example is the “Melissa virus” that was created in the late ’90s, which wreaked havoc on numerous accounts. With email being a primary form of communication for many businesses, this is one of the first areas to address. Choosing an email provider that places an emphasis on security through anti virus and spam protection is smart and should minimize your risks considerably. Ideally, they will also offer email encryption so sensitive information is safeguarded at all times.

2. Firewall

Another way to prevent viruses and other unwanted intrusions is by installing a quality firewall. This can be either software or hardware-based and will analyze the incoming data to your network. If something looks questionable and doesn’t meet security criteria, it will be blocked. A firewall works as a buffer zone between your business’s private network and the Internet, so anything malicious can be stopped before it gains access to your network. This way, you can stop problems from ever happening in the first place. The specific features and overall comprehensiveness of firewalls can vary so definitely take a look at recent reviews.

3. Wireless Network Security

It’s become common for businesses to create wireless networks via a router so multiple team members can conveniently access the Internet. The downside is that sensitive information can be leaked to external sources, which can create a host of problem when placed in the wrong hands. To tighten network security, it’s best to select a router with an encryption feature and always leave it on. Wi-Fi Protected Access (WPA) encryption is considered to be superior to Wireless Encryption Protocol (WEP) because it offers stronger encryption through temporal key integrity protocol. You may also want to turn off your wireless network after hours or during the weekend when it won’t be used for a prolonged period of time. This should reduce the likelihood of any security threats occurring on your company’s network.

4. Browser Security

Finally, there is the issue of keeping your Internet browser functioning at a high level and maximizing the security settings. For starters, you should take advantage of automatic updates if you’re using Microsoft Windows. This will ensure that your browser is continually kept up-to-date through periodic updates. Increasing password security is smart if there is the potential for outside parties accessing the Internet on the computers or mobile devices of employees. This can be done by only using strong passwords that are at least eight characters in length with a combination of numbers. If your business uses a browser like Mozilla Firefox that automatically remembers passwords, you should also uncheck “Remember Passwords for Sites.”
