Being careful about what you do online has always been important and this is increasingly so in our digital world. This means thinking about whether you should click on a link or provide your personal details. Everything you do online can and will be tracked and be used for advertising and other purposes. Consider that when you are logging into your browser or social media application.
There are many benefits provided by our digital world, ready access to information, communciation, and global collaboration. The information is not always representative or accurate. Some sites such as government departments, news outlets or research organisations may be more credible than others such as marketing or propoganda.
There are steps you can take to protect your privacy online including through your choice of browser and search engine. A VPN can also be used to mask your location and ISP which can be useful if you have a fixed IP. This makes it harder for a malicious actor to target you with a Denial of Service (DOS) attack.
Make the most of our global world but take sensible decisions. I would never recommend using it to pursue any questionable activity that could be questionable. Most governments are sensibly taking steps to be able to access Internet logs and limit potential for organised crime and other malicious activity. I am an advocate for privacy but also recognsie that the world could be a more dangerous place without that.
