Information security is about securing information, information systems and communication against damage, unlawful use, disruption, espionage and other threats.
Consider what communication services you use and how they are secured. Messages can be encrypted if necessary. Assess what messages require securing and, if necessary, secure your messages.
Your online activities leave behind a trail of personal information, for example, when you use electronic services and make purchases. This information can be stored in various registers.
Before submitting your personal information, always find out why this information is requested, what it is used for, and who is requesting the information. Information on citizens can only be used for the purpose for which it is gathered.
A secure connection in electronic services can be recognized from https: (not http:) at the beginning of the address line on the browser. Many browsers denote a secure connection with a padlock icon placed in the bottom right corner of the browser or after the address field.
