SINGAPORE: Many people would have been advised by their IT departments, service providers or the Government to “use a strong password”, “protect your passwords” and “update your software regularly”, but have no idea why these are necessary cybersecurity measures.It may be that “why” is usually not explained and if it was, explanations may have been very technical.

Unlike the patching of walls in your homes which can be expensive and may take a few days, the patching of bugs in your software and other fixes that may come with it is mostly free and takes at most a few minutes.Most modern software also have automatic patching in-built so there is no good reason why your software should not be patched with the most recent update.EASY TO IMPLEMENTBasic cybersecurity is definitely not rocket science.Unlike securing a house, the methods discussed are mostly free and easy to implement.Given that 81 per cent of data breaches are caused by weak or stolen passwords according to the Verizon Data Breach Investigations Report in 2017, adhering to such simple cybersecurity practices will definitely go a long way towards better securing your assets in a digital world.
