Do You Know Your SMB's Cyber Vulnerabilities?

Summary: A rundown of common cyber attacks, how to find the holes in your small business’s computer security, and the importance of having comprehensive and current cybersecurity.

What Common Cyber Attacks Against Small Businesses Have Grown?

Most small and midsized businesses (SMBs) are reliant on their company’s computer systems and, by extension, the internet. The rise in remote-access work made all businesses more vulnerable to cybercrime, natural disasters, and crippling downtime. As a result, companies scrambled to create secure remote-access environment for daily operations.

Q: What are the most common cyber vulnerabilities for small businesses?

A: Small businesses often face vulnerabilities such as weak passwords, outdated software, lack of employee training, unsecured WiFi networks, and phishing attacks. Limited IT resources make them easier targets, and attackers frequently exploit these gaps to gain unauthorized access, steal data, or disrupt operations.

Protecting against catastrophic events has become more complicated than ever. However, many SMBs don’t have the time, budget, or expertise to fully address the evolving cybersecurity considerations that come with remote-access work. Cyberattacks have gone up over 400% in recent years and the most common cyberattacks can bring a business’s operations to a halt and wipe out decades of effort and profit.

Q: Why are small businesses targeted by cybercriminals?

A: Cybercriminals target small businesses because they typically have fewer security defenses compared to larger organizations. Many assume they are too small to be attacked, which leads to complacency. This combination of valuable data and weaker protections makes them attractive, low-risk targets for attackers.

Unfortunately, cybercrimes have become commonplace in our business and personal lives. Perhaps your SMB has robust cybersecurity in place, and your employees carefully follow cybersecurity best practices, and you think you’ve done everything you can to protect your hard-earned data. Many large companies have been lulled into the same false sense of security, only to suffer massive data breaches. Hackers are always looking for “holes” in your cyber defenses. Here are some of the most common ones they find:

Privilege Escalation – It’s part of everyday corporate life for companies to grant specific computer system access privileges to new employees as required and appropriate for doing their particular jobs. However, companies don’t always remove or adjust previously granted access privileges as employees are promoted or moved to another department. As a result, the more “old” access credentials left from a previous position, the greater the cyber vulnerability becomes. The good news is that most entry-level or frontline employees are unlikely to have the access credentials required to install malware. However, the more the privileges are escalated, the more potential access points for cybercriminals. The simple fix is only granting employees the access required to do their jobs, but it’s vital to remove previous privileges if they don’t apply to the person’s work. Revoking access completely is essential during offboarding, as well.

Cyberattacks from Lateral Movement – Hackers look for entry points to your system. When they find one, even if it doesn’t yet allow them access to critical data, it’s a starting point from which they can do inside reconnaissance, looking for a door to the most valuable company information. Also, some businesses give administrative credentials for a specific part of their network while automatically giving access to another restricted portion of the network. Cross-network, automatic access is always dangerous. If a cyber thief gets access to one entry point, they’ll automatically get access to the second.

This “bad practice” represents another hole in cybersecurity through which hackers can gain further access to your system and laterally move across your platform until they gain access to critical business data. A common solution is air gapping, when no direct connection exists between different parts of a network. An IT security expert can install the required software, ensure that it is configured correctly, and put proper security in place.

Outdated Incidence Response Plan – Cybersecurity is constantly changing. If you created an incident response plan three years ago, it’s probably obsolete, and your data could be at risk. Cyber protection must be proactive and repeatedly tested to ensure its locked down. As cyberattack strategies change, response plans must also change so that everyone knows what actions to take in the event of a data breach. Cybersecurity best practices alone are not enough. Once an event occurs, decisive action must follow promptly, such as notifying appropriate parties, shutting down the system, and launching contingencies to become fully operational as quickly as possible.

Q: How can employees contribute to cyber vulnerabilities?

A: Employees can unintentionally create vulnerabilities by clicking on phishing emails, using weak passwords, or mishandling sensitive data. Without proper cybersecurity training, they may not recognize threats. Human error remains one of the leading causes of breaches, making employee awareness and education critical for reducing risks.

How Should SMBs Defend Against Common Cyber Attacks?

As your business increases the number of connected devices, your network vulnerability grows, too. IT security firms specialize in proactive cybersecurity and network security and have an array of affordable solutions for small and midsized businesses to defend against cyberattacks and other network data breaches.

Q: What are simple steps small businesses can take to improve computer security?

A: Small businesses can improve security by using strong passwords, enabling multifactor authentication, regularly updating software, training employees, and backing up data. Implementing basic cybersecurity practices and using reputable security tools can significantly reduce risks without requiring large investments or complex systems.
