Case 1 Today, private users and businesses extensively use computers that are connected to networks for storing and sharing valuable data. Cybersecurity is now a concern of each individual as such data as private information, banking service access details, and information about accounts the person uses are the assets for attacks. Computers are vulnerable to the loss of data, so they should be protected by several means such as cryptography technology, password security policy, or network security technology. The suggested steps to personal computer security are firewall and antivirus protection, security settings on the browser, password management, two-factor authentification, and automatic updates. The lack of protection causes risks of virus or malware intrusion, hacker attack, or identity theft. Firewall protection is the first step to network security as its main aim is to prevent unauthorized access. According to Ming, Chen, and Guo (2019), it effectively controls and supervises access between different networks and automatically rejects data information that contains risk. The computer under discussion runs on Windows 10 OS, so it already has Windows Firewall, which gives the necessary protection. Still, system security can be compromised by a user’s activity, and once it happens, the firewall is no more useful. That is why additional software for identifying and dealing with viruses and malware is required. Windows Defender is the most appropriate anti-virus in the discussed case as it suits the OS, and does not impact performance. For the aim of preventing networks from collecting user information, browser security settings should be applied. However, Easttom (2016) argues that too strong browser security settings unable access to many pages, so they need to be moderate. For example, Google Chrome browser security settings include such functions as a “Do Not Track” request for browser traffic. Additionally, one may use browser extensions, such as VPN, that provide anonymous surfing. The security of computers that use protective software can still be compromised as there are security flaws. Hackers try to identify them and create codes that target these flaws. However, the process goes both ways, and the developers are continually improving their software. To be able to have the newest and safest versions of the software, one should enable automatic updates, because outdated programs are extremely vulnerable. Encryption is another method of information protection and confidentiality. Free basic encryption solutions, such as VeraCrypt, are often sufficient for private users. Login information is a frequent target of attackers, and its theft causes catastrophic outcomes. That is why the passwords for all the services should be secure. The main recommendations for the passwords are to make them long and complex. Uniqueness means that each service a person uses must have a different password. People who use one password for all accounts put their security at considerable risk. Picking it once, attackers can access any information from any account a person uses. It is especially dangerous when a user has the same password for e-mail as for other services. With this information, hackers can access all the accounts and change their passwords. Remembering all the passwords, especially when they are complicated, is not easy
