Network security refers to the protection of your private, internal network infrastructure. Unsecured networks can lead to information leaks, data corruption and many other problems. Small businesses should be certain their networks are well-protected, even without the resources and infrastructure of larger enterprises.
Here are five security recommendations for small businesses:
- Make your employees aware of the importance of network security. Many network breaches take place because users are not aware of safe practices; users also must know why they have to correctly follow existing rules. A security policy should define the level of security and the roles and responsibilities of users, administrators and managers. Ensure that an extensive security policy is in place and users are educated about it.
- Have secure and regular incremental backups of important data of your servers. In the case of data loss, you have to be able to recover from the damage and continue working.
- Establish a strong password policy. All network devices, from routers to printers should have strong passwords. Weak passwords lead to jeopardized user accounts.
- Keep security systems up-to-date. Effective anti-virus, firewalls and other security tools on your system is not enough; these tools need to be updated and patched regularly, ensuring they are fully protecting your network and eliminating vulnerabilities that can be exploited by hackers.
- Limit and control access to sensitive information. Access to information systems that contain specific sensitive information such as files, folders and applications should be restricted unless a user needs it for their specific job function. Frequently review who has access to which data and change as necessary.
