The internet makes it easier than ever to reach customers, work remotely and run operations. It also makes every business a potential target. Cyberattacks aren't only aimed at large corporations — small and mid-sized businesses are often targeted precisely because their defences are weaker. The good news is that a few basic measures stop most common attacks.
The most common threats
- Phishing — emails or messages that trick people into clicking a malicious link, sharing passwords or paying fake invoices.
- Ransomware — malicious software that encrypts your files and demands payment to unlock them.
- Weak or reused passwords — attackers use passwords leaked from one site to break into others.
- Unpatched software — outdated websites, plugins and operating systems with known vulnerabilities.
- Insider mistakes — accidental sharing of data or misconfigured access.
Ten protections every business should have
- Turn on two-factor authentication (2FA) for email, banking, hosting, social media and any business-critical tools.
- Use a password manager so every account has a long, unique password.
- Keep software updated — operating systems, browsers, website CMS and plugins.
- Back up important data automatically, keep at least one copy off-site, and test that you can restore it.
- Train your team to recognise phishing and to verify payment requests by phone.
- Limit access so people only have the permissions they need, and remove accounts when staff leave.
- Secure your website with HTTPS, a web application firewall and regular security scans.
- Protect your network with a properly configured firewall and secure Wi-Fi, with guests kept on a separate network.
- Encrypt sensitive data on laptops, phones and in the cloud.
- Have an incident plan that says who to call and what to do if something goes wrong.
Test your defences
Assumptions aren't the same as security. A vulnerability assessment scans your systems for known weaknesses; a penetration test goes further, with security specialists trying to break in the way a real attacker would. Both produce a list of issues ranked by risk, so you can fix the most important ones first.
Monitor for trouble
Many breaches go unnoticed for weeks. Monitoring for unusual logins, malware and traffic spikes means you can respond quickly. Even simple measures — login alerts on email accounts, uptime monitoring for your website — help.
If something goes wrong
- Disconnect affected devices from the network.
- Change passwords for affected accounts, starting with email.
- Restore from clean backups rather than paying a ransom.
- Inform affected customers and report the incident as required by law. In India, certain incidents must be reported to CERT-In within the required timeframe.
- Review what happened and close the gap.
Security is ongoing
Threats change constantly, so security isn't a one-off project. Regular reviews, updates and training keep your defences current.
