The first way that technology has made your life safer is by having access to security systems from your phone and computer.  Let’s say you rushed out of the house and forgot to lock the doors or arm your home security device. Both of these activities can now be completed using a cell phone.  You can also use this when people you know want to get into your house while you are gone.  You can keep the doors locked all day until the person that wants to get into your house tells you that they are there so then you can unlock the doors.  Another way technology has made the world safer is if you need to get a hold of the police and you are in the middle of nowhere you can just use your cell phone to call whoever.  The last way that technology has made this world safer is through online banking.  Now that you can do all your banking from online you do not have to worry about people stealing your cards and spending money because you can freeze your card if it has been stolen very easily.  However, computers and other technology also makes our world less safe.  The overuse of computers and other technology can lead to increased mental health issues.  Another way computers makes this world more dangerous is from the dark web.  The dark web can give your technology viruses but even worse it can expose you to pedophiles and terrorists.  Engineers make computers safer by advising management on security improvements Firewalls and data protection systems are examples of applications that can be installed and used. Security breaches and intrusions are being monitored on networks and systems. Installing applications that assists in intrusion detection.
