Cybersecurity Basics: Protecting Your Business Online

Cyber attacks are increasing in Nigeria. Businesses of all sizes are targets. Hackers do not discriminate based on company size — they look for vulnerabilities wherever they find them.

A cyber attack can cost you money, data, customers, and reputation. Yet many Nigerian businesses have minimal security measures in place.

Here are the cybersecurity basics every Nigerian business needs.

Common Threats

Phishing attacks use fake emails, messages, or websites that appear legitimate to trick employees into revealing passwords or downloading malware. Phishing is the most common attack vector. Emails appearing to be from banks, service providers, or government agencies are common phishing attempts.

Malware is malicious software that infects your systems. Ransomware encrypts your data and demands payment for its release. Spyware monitors your activities. Viruses damage your systems.

Password attacks use automated tools to guess or crack weak passwords. Many breaches result from employees using simple or reused passwords.

Insider threats come from employees, contractors, or partners who misuse their access. Threats can be intentional or accidental.

Password Security

Use strong, unique passwords for every account. A strong password is at least twelve characters with a mix of letters, numbers, and symbols. Do not reuse passwords across different services.

Use a password manager to generate and store strong passwords. Password managers like LastPass, 1Password, or Bitwarden make it easy to use unique passwords for every account.

Enable two-factor authentication on all accounts that support it. Two-factor authentication requires a second verification step beyond your password. This prevents access even if your password is compromised.

Email Security

Be cautious with email attachments and links. Do not open attachments or click links from unknown senders. Verify unexpected emails from known senders through a different channel.

Use email security features like spam filters and phishing detection. Most business email platforms include these features. Ensure they are enabled and properly configured.

Train employees to recognize phishing attempts. Common signs include urgent language, requests for personal information, misspellings, and sender addresses that do not match the organization name.

Device Security

Keep all software updated. Software updates include security patches for known vulnerabilities. Enable automatic updates where possible. Update operating systems, applications, and security software regularly.

Use antivirus and anti-malware software on all devices. Ensure it is configured to update automatically and scan regularly.

Encrypt sensitive data on devices. Full-disk encryption protects data if a device is lost or stolen. Most modern operating systems include encryption features.

Network Security

Use a firewall to protect your network from unauthorized access. Firewalls can be hardware devices or software applications. Ensure your firewall is properly configured and monitored.

Secure your Wi-Fi network. Use WPA2 or WPA3 encryption. Change the default administrator password on your router. Do not broadcast your network name if not necessary.

Use a virtual private network (VPN) when accessing business systems from public Wi-Fi. VPNs encrypt your internet traffic and protect against eavesdropping.

Data Backup

Back up your data regularly. The three-two-one rule is a good standard — three copies of your data, on two different media types, with one copy stored offsite.

Test your backups periodically. A backup that cannot be restored is useless. Regularly verify that backups are complete and restorable.

Store backups securely. Encrypt backup data. Store offsite backups in a different physical location or in the cloud.

Incident Response

Have a plan for responding to security incidents. Who should be notified? How do you isolate affected systems? How do you communicate with stakeholders?

Document everything during an incident. This information helps with recovery and prevents future incidents.
