For many years, small business owners have lived under the illusion that their company is too small for cybercriminals to pay any attention to. However, in today’s reality, this approach is no longer viable and puts your business’s safety at great risk. Instead of wasting time cracking the multimillion-dollar perimeters of major Fortune 500 banks, hackers use automated scripts to stealthily infiltrate the systems of thousands of SMBs that keep their doors wide open to digital criminals.

As industry statistics show, the overwhelming majority of all cyberattacks happen to be aimed at SMBs. Hackers use artificial intelligence-powered spear phishing, scan for misconfigurations in cloud storage solutions, and launch destructive ransomware in bulk. Just one single data breach or extortion attempt might easily put you out of business due to extremely costly financial losses and reputational damage that follows.

However, implementing a robust cybersecurity strategy does not require millions of dollars to be spent on cutting-edge IT solutions. Proper hygiene, closing obvious holes, and educating employees are the key ingredients of cybersecurity. Here are some useful tips on how to stay safe in the era of digital threats.

1. Implement Mandatory Multi-Factor Authentication (MFA)

In today’s reality, if your SMB uses only plaintext passwords to protect your email server, financial accounts, and database systems, you live dangerously close to disaster. Hackers have developed infostealer malware and credential stuffing scripts that scan the login portal of your corporation every day checking billions of leaked password-username combinations.

Multi-Factor Authentication (MFA) is the best security measure you can implement in your SMB. MFA means adding another layer of verification to the login process. Even if a threat actor manages to steal a password of your user via phishing or leak database, he or she will fail to enter your system, because MFA implies another verification step beyond just entering the username and password combination.

Remember to set up MFA for every access point that requires high security: email accounts (Google Workspace/Microsoft 365), payroll and accounting systems, remote access VPN, cloud administrator portals. In order to increase security, it is better to suggest using dedicated smartphone authenticator apps (Google Authenticator, Microsoft Authenticator, or Duo) rather than just SMS text messages. It’s much easier to intercept the latter in a sophisticated SIM-swap attack.

2. Implement a Strict Patch Management Policy

Each time software vendors roll out a new product update, they do it for a very specific reason-to fix newly discovered vulnerabilities in their software before hackers take advantage of them to break into your corporate network. As soon as a major tech company (Microsoft, Apple, or Adobe) releases a critical security update, hackers start analyzing the patch and use automated scanning software to find businesses that haven’t patched yet.

Here is the simplest method to protect yourself from this threat vector-implement a strict Patch Management Policy. Firstly, set up automatic updates for all your corporate devices (laptops, desktops, smartphones, routers).

Secondly, don’t focus on keeping your main operating systems up-to-date. Hackers use software vulnerabilities of various third-party plugins to compromise your network. For example, it may be web browser extensions, office productivity suites, or plugins installed on your company’s WordPress website. Develop a routine that includes auditing your software and deleting all unused legacy applications.

3. Adopt the 3-2-1 Backup Strategy

Today, there are multiple financial threats faced by American SMBs, but ransomware is one of the most expensive ones. Ransomware infects your network, quietly extracts sensitive data, and executes a malicious payload to lock up all computer terminals until a ransom fee is paid in cryptocurrency. The only way to protect your business from extortion is regular data backups.

The core value of immutable cloud backup lies in its “write-once, read-many” nature. Once you upload the backup file, it cannot be modified even if a hacker manages to get administrative access. Remember to perform quarterly tests to restore your backup in case of emergencies.

4. Train Your Employees in Cyber Awareness

Even if you have the most sophisticated firewall software and endpoint protection in place, your business remains vulnerable without educated employees. As software perimeters grow more complex, hackers started focusing on human psychology. They use advanced generative AI technologies to create highly realistic and grammatically correct phishing emails that resemble the writing style of your company’s executives, suppliers, or trusted web services. 

In order to avoid becoming another statistic, train your workforce to become a powerful cybersecurity line of defense. Don’t think that cybersecurity training is a tedious annual PowerPoint presentation. Conduct monthly classes covering such topics as phishing, password hygiene, and using a corporate VPN on public Wi-Fi networks.

Also, perform quarterly phishing simulations to identify your weak links and provide additional training to the most vulnerable departments and employees ahead of an actual cyberattack.

5. Configure Least Privilege and Network Segmentation

One of the mistakes made by many small businesses is creating a flat, open network architecture, in which each user account has broad administrative privileges, and all computers are allowed to access databases without any restrictions. Under such conditions, if a malicious actor manages to distribute a malicious software payload through an email attachment to one low-level employee’s laptop, he or she will instantly compromise your entire network, including payroll system, customer databases, and servers.  

In order to prevent such scenarios, configure your corporate systems according to the Principle of Least Privilege (PoLP). Give your users access to software files, applications, and folders that are strictly necessary to perform their job functions, nothing more. There is no need for a marketing specialist to have access to payroll data, and a graphic designer shouldn’t have privileges to change your network configuration files. 

Grant administrative permissions to the minimal amount of user accounts and prohibit regular users from installing any third-party software. Also, establish a few basic rules for network segmentation and separate sensitive corporate databases (a point-of-sale payment processing machine, for example) from office Wi-Fi networks.

Frequently Asked Questions (FAQ)

Is a standard antivirus software package enough to defend my business laptops?

A consumer-grade antivirus software suite is not enough to protect your business from malicious activity. Antivirus software works by detecting malware signatures and cannot reliably detect new ransomware variants and custom scripts created by hackers. Modern businesses should implement an advanced Endpoint Detection and Response (EDR) solution. EDR platforms monitor your devices in real-time and use behavioral analysis to detect suspicious activities (like a sudden mass encryption attempt), even if the malware is unknown.

What is a supply chain attack?

Supply chain attack is a type of hacking when a malicious actor gains access to a corporation’s network not directly but through one of the trusted third-party vendors or suppliers. Small businesses are especially vulnerable to such attacks, as hackers know that large corporations have solid security perimeters, and will focus on smaller accounting practices, law firms, IT service providers, or component manufacturers trusted by enterprises. Once the SMB gets compromised, hackers use legitimate credentials to breach large enterprises. 

What should a small business consider when choosing Cyber Insurance Policy?

Cyber insurance is a necessity for protecting your business from devastating financial costs of a cyberattack. With cyber insurance, you can cover expenses associated with data breaches, interruptions in business operations, and forensic investigation. However, modern insurance providers require certain underwriting standards to provide a comprehensive policy. You need to make sure that your insurance includes both first-party and third-party liabilities and that you meet all underwriting requirements (MFA, endpoint protection, documented backup strategy). 

Should our business allow BYOD?

Allowing employees to use their own personal computers in the office poses great security risks. Personal laptops might lack proper protection, be vulnerable to cyberattacks, and even be used by non-work family members, significantly increasing chances of malware infection and accidental data leakage. If you have to implement BYOD policy in your business, use a Mobile Device Management (MDM) solution to isolate company data from personal OS and apply encryption protocols.

What should we do if we suspect a cyberattack?

If you suspect that your network has been compromised, your first move is Containment. Disconnect the infected machine from the corporate Wi-Fi network and unplug its ethernet cable to prevent the malware from spreading laterally or communicating with remote servers. Don’t shut down the computer, as this will wipe volatile memory contents needed for analysis. Contact your MSP, cyber insurance provider, and attorney to start the incident response procedure.
