The three most important security measures for small businesses

If you own a small business, you should take a look at these measures to find a starting point, although these are the minimum security measures. The three most important security measures are:

1. Anti-virus software
2. Firewall
3. Operating system patches

Anti-virus software

Today, with malicious code such as viruses, many people are still ignoring this most basic step. I have found many times how generous some people are when buying and installing antivirus software, but they are neglected to update and upgrade. What's more, some people use pirated anti-virus software. I hereby warn these users to beware of pitfalls in piracy!

Firewall

Typical small businesses use DSL or Cable modem for Internet access. Some companies use some small firewalls, such as D-Link or Linksys. They may be better than nothing. From the author's point of view, they cannot provide you with sufficient protection.

For small businesses, a more rational investment is the use of more advanced firewalls, such as application-layer firewalls. A better situation is to use unified threat management (so-called UTM) devices, which can provide you with multiple layers of network security features, such as network-based anti-virus, intrusion prevention, and anti-spam. In short, an effective UTM device can maximize your network security without exceeding your budget.

However, you have to make a choice. Because all manufacturers have done everything to promote their products. You can use the Internet to search for various buying tips and precautions. Not much to say here.

Operating system patch

In many cases, small businesses use Microsoft products such as Windows XP and Office. If this is the case for your business, then you are exposed to various risks, which can be said to be vulnerable. Because Microsoft's operating system is the most important attack target for hackers, Microsoft will release security patches every month to close vulnerabilities in the operating system. However, before you fully deploy, you may want to install a patch on one or two computers on the network to confirm that it will not cause any serious problems.

Conclusion

Someone may scoff at the author's three measures, and he may find many other measures to add to this list. However, what we are discussing here are some minimum measures. If your funds allow, you can take more professional security services.
