How To Mitigate Common Security Vulnerabilities In SMEs as small and medium-sized businesses (SMEs) continue to grow in popularity, and they also become more attractive targets for cyber attackers.

SMEs tend to have less sophisticated security infrastructures than their larger counterparts, making them an easy target for hackers looking to exploit vulnerabilities.

In this blog post, we will discuss some of the most common security risks and vulnerabilities faced by SMEs and ways to mitigate these risks.

Small businesses risk a cyber attack as much as big corporations.

Small and medium-sized enterprises (SMEs) are the top target for ransomware attacks because they may under-invest in security, have several points of vulnerability from which hackers can profit quickly enough, and not having the IT maturity level compared with larger companies.

Experts at the CBA cyber security awareness briefing noted that “without proper protections put into place,” Companies risk monetary losses alongside reputational blowback while potentially experiencing theft of intellectual property or critical customer data, all things you want to avoid when possible.

What are common cyber attacks against SMEs?


Hackers commonly use phishing to acquire users’ sensitive information, such as usernames, weak passwords, and credit card details.

The fake website looks very similar (and often identical)to the legitimate one, which requests personal details like login credentials or passcode for them to access their account on this real-life service provider’s site; therefore, it can be classified as social engineering at its finest when carried out carefully with patience.


Ransomware is becoming increasingly sophisticated and impactful, increasing business interruption costs.

Ransomware comprises malware that locks up data on the victim’s computer, typically by encryption, and payment must be made before access returns to the person who owns it (i e., you). Cybercriminal often demands bitcoin as payment to protect their identity.

This makes ransomware more complex than ever before because not only do we need new anti-malware solutions but also excellent backups.


The spread of malware through communication networks is an established cyber threat.

Recent events have shown that this type of program can cause data and financial loss, especially when it’s contagious, like in Wanna-Cry or Not-Petya cases where thousands were impacted by their effects across different companies connected to the operating systems which had been infected with them.

Sensitive data breaches

There are many reasons why data breaches happen. One of the most common is when employees share sensitive information with people who shouldn’t have access to it or if hackers take advantage of their vulnerabilities to make money off them.

Reasons for being vulnerable and how to address them

Network protection is lacking.

It is crucial to protect the IT of a company from outside threats. This includes safeguarding networked devices within an organization and any external systems connected via Internet connections or web applications on their computers.

The risks associated with these types of phishing attacks can lead not only to million-dollar losses in just one day but also seriously impaired business operations if left unchecked, which means you need cybersecurity awareness solutions designed specifically for SMEs.

It’s essential to have the right security solutions in place to protect your business from unwanted data traffic and unauthorized access.

The most common things that need monitoring are firewalls, proxy servers, or IPS (intrusion prevention systems). These all help keep an eye on what you’re doing online, for example, blocking hackers before they get too far into our business network.

Updates should be implemented regularly.

Cybercriminals are always on the lookout for vulnerabilities to exploit them. They know that if they can get into your system, you may not be able to protect yourself from malware or ransomware infection because many small businesses apply security updates with a long delay, sometimes not at all.

This creates an easy opportunity for cyberattacks by leaving a window open, which could allow virus installation within the company’s IT infrastructure without detection until it’s too late.

No solid backups

Data is an organization’s most valuable asset, and regular backups are essential to protect it from theft or damage.

Failing to back up relevant company data can result in expensive lawsuits and loss of revenue due to days-long system outages that hinder productivity while potentially compromising customer information, such as credit card numbers, so they cannot be used fraudulently.

Not having access means being unable to launch new projects, which would have generated additional income for your business if completed successfully.

A cloud backup service is one option for backing up your company data. These services allow you to store your company’s information in offsite locations securely, so if your organization’s physical location is damaged, it won’t be destroyed, and a copy will still be available to retrieve.

Some cloud backup services also offer features such as encryption and syncing, which can help keep data organized and make it easy to access from any device.

Another option is to use a traditional backup method, such as backing up your information on a physical hard drive or USB flash drive.

This option has the benefit of being more affordable than using cloud services, though you will need to ensure you have a secure location to store the external drive, such as in your office or at home. It is also important to keep multiple copies of your backups so that if one fails, you can still recover the data from another source.

Unsecure WLAN

In this age of digitalization, companies need to have strong security measures in place. The WLAN provides easy access to your corporate IT with mobile devices. Still, if you don’t take precautions now, cybercriminals can fruit access any information on those computers.

To ensure the company’s IT system is safe, they need encryption with a certain standard, such as WPA2 and separation of guest access from regular work. They also authenticate authorized users via their server structure or identify fraudulent ones (rogue).

Insufficient personnel training

If you have employees who lack IT risk and security awareness, they pose a considerable potential threat. The worst thing an unknowledgeable staff member can do is stumble upon sensitive company information by accident or intent. This may happen without warning if their cyber security training needs to be updated.

All workers must know what precautions to take when interacting online through email attachments and how social engineering attacks work (primarily). Employees also need frequent reminders about why data protection matters today s world, where big things come easily but go quickly.

A great way to achieve this is by conducting regular staff training sessions that use internal and external educational resources, including a company-specific social engineering test.

Recovery plan not in place

A disaster recovery plan is a comprehensive and detailed document that ensures an organization’s ability to continue operating in case of an IT failure.

Without one, businesses could be at risk for their continuation if they’re unable or unwilling to take steps towards ensuring continuous operations following emergencies like natural disasters, which may cause outages on computer systems (including mobile devices).

It also names specific people responsible during each stage; this way, everyone knows what needs to be done when faced with uncertainty about whether things will get back up again soon enough on account of whatever caused said problem, whether it was bad luck or something manufactured like sabotage.

Irresponsible IT security

Cybersecurity is a top priority for any company, but it’s even more necessary in small businesses that don’t have the resources to handle this issue independently. To ensure protection against cyber risk and threats and maintain an IT system with confidence, responsible people should take steps such as clearly assigning security measures across different business areas or externally partnering up when needed.

They also need regular updates about guidelines accessed by employees to clarify what can happen during recovery after something terrible happens, like hacks, attacks, etc.

In addition to assigning responsibilities and keeping employees up to date on best practices, companies should also implement security solutions that help protect against online threats such as malware, unauthorized access, and phishing scams. Some of the most common cybersecurity solutions include antivirus programs, firewalls, spam filters, and intrusion prevention systems (IPS).

How to protect SMEs from cyber threats

Antivirus software

Malware and malicious software can do a lot of damage to your business, so you must protect yourself from those risks. Antivirus software will protect all the computers in your company against viruses and other online threats like ransomware or Data triumphant wannabe hackers who want access for themselves rather than what is rightfully yours.


Patching is a vital tool to keep your IT systems up-to-date. It ensures that the software and firmware on your equipment, from computers down to even phones, are always in sync with current versions from developers or hardware suppliers, which helps improve security.

Monitor USB drives

With the recent rise in cyber criminals’ activities, it is more important than ever for companies to protect themselves from potential risks. How can you do this without inhibiting productivity or creativity within your business?

Implementing restrictions on which files are shared via USB drives and memory cards.

By keeping employees away from potentially harmful content like malware-laden software that could crash their computer system when opened (or even just accessed), they’ll be able not only to keep up with work deadlines but also feel safe while doing so, knowing there’ll never come any moment where assets needlessly lost because someone clicked “yes” next time around during installation.


All it takes to protect your computer network from external threats are some simple steps. The essential step is activating the firewall on all of your devices and then following that up by adding trusted sources to their respective lists so they can be identified as such when scanned for eligibility during boot time or through Windows Update automatically.

Employee training

Cybersecurity is a hot topic these days, which needs to be addressed by all of us as individuals and members of society. If we don’t ensure our own safety online, then there’s no telling what could happen.

So first off: do some research on how best you can keep yourself protected against cyber-attacks before making any decisions about education for employees or other potential dangers present themselves; secondly, make sure everyone knows exactly where they stand when it comes to this issue because confusion leads directly into vulnerability (whether maliciously meant or Accidental)

Multi-factor authentication 

Implementing an extra step in the login process goes a long way to protecting your company and clients’ information online.

Stronger passwords

The best way to keep your company safe from hackers is by using strong passwords and not sharing them with anyone. You can also train employees in cyber hygiene, so they know what’s essential to protecting the data on their own devices or computers.


So there you have it – four of the most common security vulnerabilities in SMEs and how to mitigate them. Of course, this is just a snapshot; there are many other ways your business can be compromised if you’re not careful.
