Improving cyber security in your business is not just about spending money. Here are 12 practical steps you can take that do not cost anything other than your time:
- Remove Adobe Flash Player from any machines if installed
- Remove Oracle Java from any machines that do not need it (see www.java.com)
- Remove Microsoft Silverlight from any machines if installed
- Run all users as standard users rather than as administrators in Windows
- Scan computers with an online scanner at least once a month from a different antivirus company than the one you have installed (for example Eset, F-Secure, Sophos, Trend Micro)
- Educate your staff about the worst passwords of 2023 and not to use their year of birth as a phone PIN
- Encourage staff to use personal devices for personal internet use
- Block any email attachment that has executable content or the attachment's file extension matches .js or .lnk or .mht or .url or .wsf (for more info see Office365 tips)
- Make sure that you are using legitimate up to date software, keygen utilities often contain malware
- Install the Avast Anti-Ransomware Protection & Removal Tool (https://www.avast.com/c-ransomware-protection-tool) if you are using Windows Defender as your only antivirus software
- Consider changing your DNS settings to Quad9 (9.9.9.9) if you do not already filter DNS
- Show all File Name Extensions so you can spot program files posing as documents like SOMETHING.DOC.EXE or SOMETHING.PDF.EXE as the last dot and 3-4 characters would normally be hidden on
Microsoft Windows machines
