1. Describe three ways that computers have made the world safer and less secure.

Computers have made the world safer in three ways:

– FINGERPRINTS REPLACE PASSWORDS: Traditionally, access to a secure personal computer is granted via a typed password. Now many devices are equipped with an unlock option with a fingerprint scan. Hackers might be able to guess your password, but it will be quite difficult for them to reproduce your fingerprint!

– LOCK YOUR DOORS AND ARM YOUR REMOTE SECURITY SYSTEM: Suppose you left the house in a hurry, forgetting to lock your doors or arm your home security system. Both tasks can now be performed via a mobile phone. This is also useful for house keepers, dog walkers or any other trusted party who may stop while you are away from home. Keep the doors locked all day until the scheduled arrival of the friend in question, then allow access as simply as by pressing a digital switch.

– SAFER BANKING: If you do your banking online, it may be useful to synchronize your personal computer with your digital bank account. In addition to making your username and password mandatory when connecting, the program requires that you access them via a specific device (s) previously decreed by you as safe. If you strengthen these computers with fingerprint or facial recognition security, yours will be a hard-to-break safe even if your account information gets into the wrong hands.

Computers have made the world less secure in three ways:

– Cyberattacks: they are today the basis for the closure and fall of several large companies.

– Digital technologies: they influence the economy, politics and society. Hacking digital data has a huge impact on society.

– New software: the misuse of new software leads to the vulnerability of our computers, which very often leads to hacking of our data in different fields.

2. How do engineers make cyber networks safer? A. To secure networks against external attacks, engineers have several tools:

1. A firewall, which analyzes and regulates all traffic from outside before entering the server. This prevents most attacks from entering the server.

2. An IPS (“Intrusion Prevention Systems”), which is able to adapt to situations and reacts according to traffic at time “t”. 3. A mail antivirus, which scans all emails before delivering them to their recipients. 4. Then there are also regular updates to our servers, which allow us to address the potential vulnerabilities of the company’s servers and workstations.

B. Secure workstations. The workstations must be invulnerable, so I manage updates daily to fight against any faults. For this, I take care:

1. installation and centralized management of an Antivirus Firewall to protect them locally.

2. protection of mobile workstations. That is, on our employees’ laptops, data and hard drives must be encrypted so that no sensitive company information can be accessed if the machine is stolen.

C. Protect information (confidential documents, etc.). Because your bank needs to protect your banking information, we need to make sure that the data we store is encrypted. Indeed, the encryption of data makes them unusable, even in the event of theft. However, I would like to point out that in order to steal such data, you must first go through the security systems mentioned above.”
