As a small to medium-sized enterprise (SME) in the UK, safeguarding your business against cyber threats is crucial. Phishing attacks, in particular, pose a significant risk, targeting firms of all sizes, but can have a huge impact on smaller businesses.
Phishing can lead to data breaches, financial losses, and reputational damage, which can have catastrophic effects on a company of a smaller size.
Understanding phishing attacks
Phishing attacks are attempts to obtain sensitive information by appearing online as a trustworthy entity. These attacks often come in the form of emails, messages, or websites that appear legitimate but are designed to steal data such as login credentials, financial information, or personal details.
Phishing attacks can have devastating practical consequences for small and medium-sized enterprises (SMEs). A single successful attack can lead to severe data breaches, compromising sensitive customer and business information.
This often results in substantial financial losses, not only from immediate theft but also from the costs associated with mitigating the breach and strengthening security measures post-incident.
Additionally, the reputational damage inflicted by a phishing attack can be particularly hard for an SME to overcome. Unlike larger corporations, SMEs often lack the extensive resources needed to rebuild trust and may face a significant loss of customers, potentially pushing the business towards bankruptcy.
The erosion of customer confidence can have long-lasting impacts, making it incredibly challenging for an SME to recover and regain its market position.
Common types of phishing attacks on SMEs
- Email phishing: Fraudulent emails that appear to be from reputable sources, urging recipients to click on malicious links or attachments.
- Spear phishing: Targeted phishing aimed at specific individuals within an organisation, often using personal information to appear more convincing.
- Smishing: Phishing via SMS text messages, tricking recipients into revealing sensitive information or clicking on malicious links.
- Vishing: Voice phishing, where attackers use phone calls to impersonate trusted entities and extract confidential information.
5 Steps to protect your SME from phishing attacks
1. Employee training & awareness
Educate your staff: Regularly train your employees to recognise phishing attempts. Conduct workshops, webinars, and simulations to keep them informed about the latest phishing tactics. This ensures everyone is more aware of the risks.
Educate your senior management: Train your management teams to ensure that they can guide the individuals they lead. Senior management should be able to instil the importance of guarding against this information security risk.
2. Implement robust email security
Spam filters: Use advanced spam filters to detect and block phishing emails before they reach your employees' inboxes.
Multi-Factor Authentication (MFA): Require MFA for accessing email accounts to add an extra layer of security, this could be set up by anyone in the company and are free across leading email hosting providers such as Google and Microsoft.
3. Strengthen password policies
Having all employees sign a password policy that provides guidelines on the most secure passwords is key and should be monitored and actioned by the HR team with other major policies. These policies should include guidance on:
Strong passwords: Enforce the use of strong, unique passwords that are changed regularly with policies urging routine administration.
Password managers: Encourage team managers to enforce the use of password manager apps to generate and store complex passwords securely across key business areas.
Avoid password reuse: Ensure employees do not reuse passwords across different accounts.
4. Secure your network
Firewalls and antivirus software: Use reputable firewalls and antivirus software to detect and block malicious activities, ensuring a robust first line of defence against cyber threats. Select and install well-reviewed security solutions and configure them to provide real-time protection. This is important as it helps prevent unauthorised access and malware infections that can compromise your business data.
Regular updates: Consistently update all software, systems, and applications to protect against vulnerabilities and reduce the risk of exploitation by cybercriminals. Enabling automatic updates where possible and regularly scheduling manual updates for systems that require them is important because outdated software is a common entry point for attackers seeking to exploit known security flaws.
Network segmentation: Implement network segmentation to limit access to sensitive information, thereby reducing the potential impact of a breach and enhancing overall security. Divide your network into segments based on user roles and data sensitivity, using firewalls and access controls to manage traffic between segments. This is important because it minimises the spread of an attack, confining potential damage to smaller sections of your network.
5. Develop an incident response plan
Preparation: Create a detailed incident response plan that outlines the steps to take in the event of a phishing attack.
Incident response team: Establish a dedicated team responsible for managing and mitigating phishing incidents.
Regular practice: Conduct regular practice runs to ensure your team is prepared to respond quickly and effectively to a phishing attack.
Phishing attacks are a significant threat to SMEs, just like they are to any size business, but with proactive measures and a strong security culture, the risk can be significantly reduced.
By educating your employees, implementing robust security measures, and preparing for incidents, you can protect your business from the damaging effects of phishing.
