13 Tips to Secure Your Small Business from Cyberattacks in 2021

Find out how to secure your small business

Have you already thought about how to protect your small business from cyber threats? It is worth starting as early as possible. Small businesses are more vulnerable to breaches and hacks than larger ones, simply because they’re often unprepared for the attack.

You can always start with a Free Security Health Check by BSG team of security professionals, but what should be your next step? 

Review the BSG tips on cybersecurity for business:

Encrypt backup data

Encrypting Backup Data is used to give you personal control over sensitive information. The information is securely stored on all your devices, from your smartphone to your computer. 

Note: You must remember your encryption password, as your data can not be accessed without it.

Data encryption not only protects your system from cyberattacks but can also increase the trust of your customers.

Most customers claim that they do not purchase on sites that do not have an SSL certificate.

*SSL stands for Secure Sockets Layer, which is a standard security protocol. It helps protect sensitive data that is transferred between the server and the browser by using encryption. Thus, it is challenging for cybercriminals to gain access to this data and somehow modify it.

When a site uses an SSL certificate, customers can easily make financial transactions there and trust the site. So, this is beneficial for small businesses’ Internet security.

Businesses need regular backups. Never keep passwords and encryption keys together – eliminate potential security risks.

Remember, encrypted backups are a valuable tool to protect your data from security attacks and reputation losses. Still, it is always up to you to choose: the risk of being hacked or the opportunity to prevent data breaches and security incidents.

Train your employees on cyber security awareness

Most of your employees are likely to know very little about cybersecurity, but you can train them. When considering steps to protect the security of your business, remember that one of the main threats is not technological, but biological. 

More than 90% of all cyber attacks start with spear-phishing attacks on your employees, who inadvertently open emails and receive malware on their devices.

Every employee needs to know:

  • How to protect passwords and rules of how to create them;
  • How to use MFA and how it decreases an attack surface;
  • How to treat business information at home and work;
  • How to recognize the most frequent information security threats and create an actionable plan.

Ask your trustworthy security service provider for security awareness training.

cybersecurity breaches are caused by human error

Limit employee access to all data & information

Keep track of the level of access that employees have to your data – limit redundant access to prevent data breaches. The fewer people have free access to valuable data, the lower the risk of human error that is most often the cause of information security threats. 

Just don’t give employees more access than they need for what they do at work. If an employee leaves or moves to another position, remove his access and passwords to minimize security threats.

A pinch of access prevention can amount to a ton of protection when it comes to limiting the influence of a disgruntled former employee.

Use multifactor authentication

Multifactor authentication (MFA) or two-factor authentication (2FA) is a security technology that requires a mix of authentication methods from independent credentials – Google Authenticator, security keys, email, SMS. For example, using a password together with a code sent to your smartphone for self-authentication, etc. 

But even if you use multifactor authentication, it is certainly not 100% protection against hackers. In this case, they will have to spend much more effort, or perhaps, move to an easier victim.

There are different types of MFA; their effectiveness slightly differs depending on how they are used. Physical security keys are considered one of the most powerful forms of MFA. For example, you can purchase a security key Yubico. This MFA method will allow you to associate your account with the key, and no one will be able to log in there until the key is in the device.

If it is not possible to use this tool, then apply another way of MFA – for example, programs such as Google Authenticator or Microsoft Authenticator, etc. Such applications are more reliable than just SMS to a smartphone with a code.

Perform a regular risk assessment

Risk assessment is an essential part of any small business security plan. Analyze all potential threats regularly to identify possible gaps in the security system of your company. Identifying possible threats will help you plan how to plug any of them.

As part of the risk assessment research, check all your data: 

  • How the data is stored, and who has access. 
  • How people with different access levels can bypass it and who might potentially want to do it. Determine the possible course of events and the level of risk if breaches do occur.

After completing your threat identification analysis, define your security strategy. Remember to regularly review and adjust the strategy to ensure more intensive data protection and following up on your security awareness program.

Keep software and operating systems updated

Some people neglect to update the operating system and other software they use in business. Don’t be one of them.

Even if you have automatic updates on all applications and software, check manually for updates. Anything can happen – from an error to the fact that you run out of memory on your hard disk, and there is no space left to download patches.

Each update of your software is more secure than the previous version. The developers in each version fix bugs and loopholes that hackers could exploit, so stay tuned.

Install firewall software

Firewall software also helps protect your business; it can thwart intruders and keep employees browsing dangerous websites. We advise you to install and continuously update firewalls on all devices of your employees.

Don’t forget off-site employees, even if you use a CSP (cloud service provider) or a VPN (a virtual private network). If you want to provide a more significant level of protection, you can install IDPS (intrusion detection/prevention system).

cybersecurity risks are increasing

Take care of networks security & endpoint protection

Think not only about protecting the internal system but also about networks security and endpoint protection. Use these router best practices for secure wireless networking:

  • Change the administrative password on new devices
  • Set the router to use WiFi Protected Access 2 (WPA-2), with the Advanced Encryption Standard (AES) for encryption
  • Don’t use WEP (Wired-Equivalent Privacy)
  • Set the wireless access point so that it does not broadcast its SSID (service set identifier).

If you are going to give wireless internet access to your customers, then separate it from your business network.

Personal data involved in breaches

Set up web & email filters to recognize phishing

Small business security threats abound, from phishing to ransomware, but web and email filters can help. Use them to prevent potential attacks. 

This will help not to clog your mail with spam and will deter hackers.

Warn employees about visiting unsafe sites, such as social media or pornographic ones. You can even create a “black list” for them because just one employee needs to see such a website to unintentionally download malware onto the entire company’s system.

Choose a secure cloud – protect data and eliminate risks.

Using cloud storage will increase your level of security, but do not trust it with absolutely all data. Send the archived data to the server, but those that you constantly use – to the cloud.

To choose the proper cloud storage, study all the possibilities that will open before you buy the premium version. Reliable options are Azure, AWS, and GCE. The main thing is to remember to use strong, unique passwords and store them in a password manager.

Do not think security is not a priority for small business

Don’t believe the stereotypes that hackers aren’t interested in your small businesses, and there is no need to worry about security. 

Try to learn as much as possible about cybersecurity before you start securing your systems, and, indeed, don’t wait for a data breach. There are many more sources for studying cybersecurity now than before, so you should only highlight the most reliable of them.

Even at a basic level, you can already understand how protected your data and accounts are and whether it is easy to compromise them. To do this, pay attention to how to view and decipher high-level network logs. 

Learn to create appropriate firewall rules. It is definitely won’t save you from an advanced security attack, but a well-designed network can solve many of the essential weaknesses that cause security breaches.

*Note: Review the documentation of your cloud service provider while using.
