Today, small businesses are increasingly becoming targets of cyber threats. Despite their size, these enterprises hold valuable data and assets that are attractive to cybercriminals. From customer information to financial records, the stakes are high for small businesses when it comes to cybersecurity. This is why having a robust cyber incident response plan is not just a good idea but a necessity for their survival and growth.

What is cyber incident response?

A cyber incident refers to any occurrence that could potentially compromise a company's data or systems' confidentiality, integrity, or availability. Such incidents encompass a variety of events, including data breaches, unauthorised access, illegal data manipulation, unauthorised alterations to data, and attempts to disrupt or deny services. In the wake of a cyber incident affecting any organisation, it's crucial to have a clear understanding of the situation to promptly and effectively respond, safeguarding the company's assets, operations, and reputation.

Cyber incident response involves the systematic approach adopted by organisations to prepare for, react to, manage, and mitigate the impact of cyber incidents, thereby safeguarding assets and operations. Its primary objective is to minimise the disruption caused by attacks and expedite the restoration of operations. Crafting and resourcing an efficient response plan poses a significant challenge for small and medium-sized enterprises (SMEs), yet its significance cannot be overstated.

The threat landscape for small businesses

For small businesses, the impact of a cyber incident can be devastating. Beyond the immediate financial losses, there are also reputational damages and legal repercussions to consider. Without a proper response plan in place, a single cyber incident has the potential to cripple or even bankrupt a small business.

Contrary to popular belief, small businesses are not immune to cyber threats. In fact, they are often seen as easier targets by cybercriminals due to their limited resources and less sophisticated cybersecurity measures. According to Kaspersky's data for Singapore, cybercriminals are consistently targeting small and medium-sized businesses (SMBs) in the city-state. During the first half of 2023, employees of these SMBs encountered malware or unwanted software masquerading as business applications, with around 50 distinct files being distributed during this period. This led to the detection of approximately 453 distinct attacks. In contrast, the first half of 2022 witnessed the distribution of only 24 unique files and the detection of 112 unique attacks. This highlights the urgent need for better cybersecurity practices in this sector.

Common cyber threats facing small businesses include:

1. Phishing attacks: Cybercriminals use fraudulent emails and messages to trick employees into revealing sensitive information or downloading malware.

2. Ransomware: Malicious software that locks users out of their systems or encrypts files until a ransom is paid, often crippling businesses until resolved.

3. Data breaches: Unauthorised access to sensitive data, such as customer information, leading to potential identity theft and financial fraud. These breaches often stem from cybersecurity misconfigurations that invite data breaches.

4. Supply chain attacks: Hackers target third-party vendors or partners to gain access to a small business's network or data.

The cost of cyber incidents

The cost of cyber incidents for small businesses extends far beyond immediate financial losses. There are also indirect costs such as:

• Lost revenue: Downtime caused by cyber incidents can result in lost sales and revenue.
• Reputation damage: A breach can erode customer trust and loyalty, leading to long-term reputational damage.
• Legal consequences: Non-compliance with data protection regulations can result in hefty fines and legal penalties.

Given the high stakes involved, investing in cyber incident response is not just about protecting data and systems – it's about safeguarding the future of the business.

The importance of preparedness

Prevention is always better than cure, but in the world of cybersecurity, no system is entirely foolproof. That's why small businesses need to be prepared for the worst-case scenario. A proactive approach to cybersecurity, including robust incident response planning, can significantly reduce the impact of a cyber incident.

Key elements of an effective cyber incident response plan include:

• Incident detection: Early detection is crucial for minimising the damage caused by a cyber incident. Implementing security measures such as intrusion detection systems and security monitoring can help identify threats before they escalate.
• Response team: Designate a team responsible for managing cyber incidents, including IT personnel, security experts, and senior management.
• Containment and mitigation: Act quickly to contain the incident and prevent it from spreading further. This may involve isolating affected systems, revoking access credentials, and deploying security patches.
• Communication plan: Keep stakeholders, including employees, customers, partners, and regulatory authorities, informed throughout the incident response process.
• Post-incident analysis: Conduct a thorough review of the incident to identify lessons learned and improve future response efforts.
