I started my IT career way back in 1990. At that time it was all 286 386 PC’s and computerization had just started. At that time the kind of IT and security awareness was very very minimal. Computer virus was considered as a big threat and if it makes an entry into any computer or IT environment then it use to cause a big panic across the organization. To counteract the virus the antivirus file definitions was the only remedy and to keep all systems with latest file definitions. IT staff had to spend lot of time in ensuring that all computers are updated in a timely manner. Since that time the overall Cybersecurity has undergone a much awareness and lot of things are done and still underway to ensure that the computer systems are latest and necessary precautions are taken to keep the cyber attackers are kept away.
