Protecting Your Business from Modern Cyber Threats

 

At ACS Norwich, we help businesses stay secure in an increasingly connected world. Cyber attacks are becoming more sophisticated, and organisations of all sizes can be targeted.

​

The good news is that many security incidents can be prevented by following a few essential best practices.

​

Use Strong Passwords

 

Weak passwords remain one of the most common causes of account breaches.

 

We recommend:

​

• Using a unique password for every account

• Creating passwords with at least 12 characters

• Using a password manager to generate and store passwords securely

• Avoiding personal information such as birthdays or pet names

• Changing passwords immediately if you suspect they have been compromised

​

Enable Multi-Factor Authentication (MFA)

 

Where available, always enable Multi-Factor Authentication (MFA).

 

MFA adds an additional layer of protection by requiring a second verification step, such as:

• Authenticator app approval

• Security key

• One-time code

 

Even if a password is stolen, MFA can prevent unauthorised access.

​

Be Aware of Phishing Emails

 

Phishing remains one of the most effective methods used by cybercriminals.

 

Be cautious of emails that:

​

• Create a sense of urgency

• Ask for passwords or financial information

• Include unexpected attachments

• Request bank detail changes

• Contain suspicious links

 

If you're unsure, verify requests through a separate communication channel before responding.

​

Keep Devices Updated

 

Software updates often contain important security fixes.

 

Ensure that:

​

• Windows updates are installed regularly

• Business applications remain current

• Mobile devices receive security updates

• Antivirus and security software are up to date

 

Delaying updates can leave systems vulnerable to known threats.

​

Back Up Your Data

 

Data loss can occur due to:

​

• Hardware failure

• Human error

• Cyber attacks

• Ransomware

 

Maintain regular backups and ensure they are:

​

• Automated where possible

• Stored securely

• Tested regularly

• Protected from ransomware

 

A reliable backup strategy can be the difference between a minor disruption and a major business crisis.

​

Secure Your Wi-Fi Network

 

Your wireless network should be properly protected.

​

Best practices include:

​

• Using strong Wi-Fi passwords

• Enabling WPA2 or WPA3 encryption

• Changing default router credentials

• Keeping networking equipment updated

• Restricting guest access where appropriate

• Network isolation & segmentation

​

Protect Remote Workers

 

With hybrid and remote working now common, businesses should ensure staff can work securely from anywhere.

​

We recommend:

​

• Using VPN access where appropriate

• Enabling MFA on all business systems

• Securing company-issued devices

• Encrypting laptops and mobile devices

• Providing staff cyber-security awareness training

​

Train Your Employees

 

Technology alone cannot prevent cyber attacks.

 

Regular staff training helps employees:

​

• Recognise phishing emails

• Identify scams

• Handle sensitive information safely

• Follow company security policies

• Report suspicious activity quickly

• ​

Well-informed employees are one of the strongest lines of defence against cyber threats.

​

What To Do If You Suspect a Security Breach

 

If you believe your systems or accounts have been compromised:

​

1. Disconnect affected devices from the network.

2. Change passwords immediately.

3. Enable or review MFA settings.

4. Contact your IT support provider.

5. Preserve any evidence of suspicious activity.

6. Inform relevant stakeholders if required.

​

Acting quickly can significantly reduce potential damage.
