Software Security Best Practices Every Business Should Demand
The security practices every business should expect from its software and website, from secure coding and updates to backups and incident response.
Cyber attacks are not just a problem for banks and large enterprises. Small and mid-sized businesses are frequent targets precisely because their defences are weaker. Hacked websites get filled with spam, customer data gets stolen and search rankings collapse. The good news: most attacks exploit a handful of well-known weaknesses, and they can be prevented.
Key takeaways
- Keep everything updated: outdated plugins, libraries and servers are the top cause of breaches.
- Follow OWASP guidance to prevent common flaws like injection and broken access control.
- Use strong authentication: two-factor login and least-privilege access everywhere.
- Back up, monitor and plan, so you can detect and recover quickly.
The most common ways business software gets hacked
- Outdated software: old WordPress plugins, themes, frameworks and libraries with known vulnerabilities
- Weak or reused passwords for admin panels, hosting, email and databases
- Broken access control: users can see or change data they shouldn’t
- Injection flaws: SQL injection or command injection through unvalidated input
- Misconfiguration: exposed admin panels, debug modes, open storage buckets
- Abandoned plugins or code left on servers and forgotten
Security practices to demand from your developers
Secure coding
Developers should follow the OWASP Top 10 guidance: validate all input, use parameterised queries, encode output, enforce authorisation on every request, and avoid storing secrets in code.
Authentication and access
Enforce strong passwords and two-factor authentication for admins, use role-based access, and give each person only the permissions they need.
Data protection
Encrypt data in transit (HTTPS everywhere) and sensitive data at rest. Collect only the personal data you need, as required by India’s Digital Personal Data Protection (DPDP) Act.
Dependency and patch management
Track every library and plugin, update regularly, and remove anything unused. Automated tools can flag known vulnerabilities in dependencies.
Backups and recovery
Keep automatic, off-site backups and test restoring them. A backup you have never restored is only a hope.
Monitoring and incident response
Log important events, monitor for unusual activity, and have a written plan for what to do if something goes wrong: who to contact, how to isolate systems and how to notify users.

Website-specific checklist (WordPress)
- Remove unused plugins and themes completely
- Keep core, plugins and themes updated
- Use a web application firewall and malware scanning
- Limit login attempts and enable two-factor authentication
- Hide or protect admin and XML-RPC endpoints where not needed
- Review admin users regularly and remove unknown accounts
Security is a process, not a product
Schedule periodic reviews, penetration tests for critical systems, and make security part of every release, not an afterthought.
Frequently asked questions
Our website was hacked. Can you help?
Yes. We clean malware, remove spam content and backdoors, close the vulnerability that was exploited, harden the site and set up monitoring to prevent a repeat.
What is the OWASP Top 10?
It is a widely used list of the most critical web application security risks, published by the Open Worldwide Application Security Project, and a good baseline for secure development.
How often should we update our software?
Security updates should be applied as soon as they are tested, and a routine maintenance cycle, often monthly, keeps everything current.
