There are a number of ways businesses use cyber security. One is to protect their networks and information from external threats. This includes things like installing firewalls and other security measures to keep hackers out. Another way businesses use cyber security is to safeguard their data from internal threats. This can include things like developing policies and procedures to prevent unauthorized access to sensitive information, as well as encrypting data so that it can’t be read if it falls into the wrong hands. Finally, businesses may use cyber security measures to comply with industry regulations or laws, such as the Health Insurance Portability and Accountability Act (HIPAA) in the US and GDPR and Cyber Essentials in the UK.
