One of the most important things you can do to improve cyber security for your business, at home and with your family and friends is to have a conversation about this. Many breaches occur because people are not aware of what they can and should be doing to protect themselves. Phishing attacks are an example of how your security at work or home can be compromised by someone making a mistake and clicking on a malicious link. By talking to others about this you are helping to raise awareness of the risks and what to do.
Most large organisations will have provided cybersecurity training to all of their employees and others who access their system. This is something that you should be considering in your business or organisation. It is also sensible to talk to your family especially young children about how they use the Internet and how to protect themselves. It is possible that once a user or device is compromised for hackers to access other devices and accounts on the same network. By raising awareness you are reducing the likelihood of that occurring.
Reporting is also crucial because when incidents are not reported they could remain undetected and that could allow more damage to be done. Reporting a breach or suspected breach means that you have the opportunity to manage it and ideally prevent similar incidents recurring. For smaller organisations and at home it means being able to have a discussion about what occurred and what action is needed. This might involve scanning for viruses to remove infections and putting in place additional access controls.
You should also monitor your systems to check for vulnerabilities and detect any unusual activity. Your router firewall can provide some capability for that and gives an opportunity to check and update your firewall settings. Security software is also useful for alerting you when programs require updating or a regular system scan has not completed. When you do that you can also review your backup routine and operations.
