Surviving the Cyber Jungle: A SMB’s Guide to Cyber Security

The internet can feel like a jungle sometimes – one wrong step and your business could fall victim to the many cyber security threats lurking in the shadows. As a small or medium-sized business (SMB), you may need more resources or expertise than large enterprises do, but that doesn’t mean you are powerless against cyber attacks. This guide will equip you with practical tips and tools to help your SMB survive and thrive in the cyber jungle.


Assume You are Under Attack and Take Proactive Measures

The first step is adjusting your mindset. SMBs often mistakenly believe they are too small to be targeted, but the reality is that over 60% of cyber attacks target small businesses. Cybercriminals go after the low-hanging fruit and count on SMBs having lax security. Assume your business is constantly under attack, so you are motivated to take proactive precautions.

Prioritise Encrypting and Backing Up Critical Data

Your customer and business data is invaluable, so lock it down. Encrypt sensitive data like financials, customer info, trade secrets, etc. so it’s indecipherable without a key. Back up data regularly both on-site and off-site/in the cloud so you have multiple copies if disaster strikes. Cyber attacks often involve stealing or encrypting data and holding it for ransom, so make your data defence a top priority.

Maintain Strong Defences by Patching Frequently

Cybercriminals exploit vulnerabilities and weaknesses to break in, so eliminating these openings is key. Always update to the latest software, operating systems, apps, etc. to plug holes as they’re discovered. Enable automatic updates wherever possible. If auto-updates are unavailable, set calendar reminders to manually update regularly. Updates can be tedious but are your frontline defense.

Deploy Next-Gen Antivirus for Endpoints

Your endpoints – devices like computers and phones where users interact with your network – are prime targets for cyber attacks. Install next-gen antivirus software on all endpoints to continually scan for and eliminate viruses, malware, phishing scams, and other threats trying to gain a foothold in your network. Many antivirus tools also have firewalls to hide your endpoints from plain view.

Quarantine Untrusted Traffic with a DMZ

A DMZ or demilitarized zone acts like no man’s land between your internal network and the open internet to separate public-facing services like websites from the rest of your infrastructure. It quarantines traffic that hasn’t been fully verified as safe before allowing it into your core systems. Segmenting your network like this contains damage from attacks on outward-facing services so they can’t spread.

Lock Down Physical Access to Systems and Data

While cyber security focuses on digital threats, physical breaches can also compromise your data and systems. Ensure server rooms and technology infrastructure are behind locked doors with keycard or biometric access limited to IT staff only. Shred old documents containing sensitive info rather than just trashing them. Security cameras, alarms, and guards can also deter physical attacks or unauthorised access. It may seem low-tech, but don’t leave physical backdoors open!

Train Employees to Spot and Avoid Phishing Attempts

Phishing uses emails, fake websites, and downloads to fool victims into handing over login credentials or sensitive data that let cyber criminals infiltrate your network. Train employees to recognise telltale signs of phishing like suspicious links, odd sender addresses, and urgent threats demanding immediate action. Empower staff to report anything suspicious for further inspection before taking action. Ongoing education is essential since phishing techniques are constantly evolving.

Limit Access to Only What is Needed

Don’t give users more access to systems, data, and controls than their role requires – this is called the principle of least privilege. For example, limit accounting staff access to financial systems only rather than the whole network. This contains damage from stolen credentials or compromised accounts by limiting what attackers can reach. Integrate the principle of least privilege into your cyber security policies and enforce it through access controls across your infrastructure.

Leverage AI to Detect Anomalies

AI that analyses patterns in data can detect cyber security anomalies and threats much faster than humans reviewing system logs. Deploy user behaviour analytics that establishes baselines for normal activity and then flag deviations that could signal insider threats. AI analysis of system traffic and access patterns can also catch stealthy attacks that evade traditional security tools. AI is getting better at recognising new methods of attack so you can respond before major damage occurs.

Make Security a Company-Wide Culture

Technical measures will only get you so far – building a culture of cyber awareness within your organisation is critical too. Include cyber security in new employee onboarding and conduct recurring training to ensure best practices like strong passwords are habits for everyone. Emphasise that all technology users, not just IT staff, have a key role in protecting systems and data. Lead by example in applying security measures and never chastise staff who report concerns – you want to encourage openness.

Partner with MSSPs for Expert Skills and Resources

You don’t have to go it alone in the cyber jungle! Managed security service providers (MSSPs) offer SMBs enterprise-level cybersecurity skills, technology, and resources at affordable, flexible price points. MSSPs monitor your defences 24/7, rapidly detect and respond to threats, perform security audits, and provide ongoing recommendations to improve protections. Augmenting lean internal IT teams with MSSPs gives you strength in numbers against cyber attacks.

Surviving in the cyber jungle requires vigilance and proactive precautions, but armed with the right guidance SMBs can develop an effective cyber security plan. Treat security as an ongoing effort rather than a one-and-done project. Continuously educate yourself on emerging threats, double down on defensive measures, and partner with trustworthy allies. With grit and perseverance, you can not only survive but thrive in even the most treacherous cyber terrain.


Frequently Asked Questions

What are the most common cyber threats targeting SMBs?

The top cyber threats SMBs face are phishing, ransomware, malware, man-in-the-middle attacks, insider threats, unsecured endpoints, outdated software, and lack of employee training.

What’s the #1 step SMBs can take to improve cyber security?

The most impactful step is training employees to practice good cyber hygiene like strong passwords, identifying phishing attempts, reporting suspicious activity, not clicking unverified links/attachments, and following cyber security policies. Humans are the weakest link so educating staff makes a huge difference.

How can SMBs defend against ransomware?

Key measures include blocking suspicious file attachments/links, keeping software updated, enforcing least privilege access, backing up data regularly, using next-gen antivirus to detect threats, segmenting networks, and considering cyber insurance if attacked.

Should SMBs rely on antivirus software alone for cyber security?

No, antivirus is an important layer of defence but not a silver bullet. SMBs need a defence-in-depth approach combining antivirus, firewalls, employee training, access controls, encryption, patching, backups, physical security, and expert partners like MSSPs.

How often should SMBs train employees on security awareness?

Cyber security training should not be a one-time event but rather an ongoing program to keep employees vigilant against evolving threats. After initial onboarding training, conduct refresher courses at least quarterly via brief module-based training, simulated phishing tests, and mandatory cyber security newsletters.
