In this era of ubiquitous cyber risks, it is crucial to enhance e-mail privacy. The first step in making sure that no one other than the intended sender (unauthorized sender) and receiver can read an email is to use end-to-end encryption. This safeguards data during transmission from unauthorised parties. Secondly, in order to prevent security flaws that hackers could take advantage of, users should ensure that their email clients and devices are routinely updated. The most recent security fixes are always installed when software is kept up-to-date (Alharbi, 2023).

Third, in order to increase the level of protection, you can enable two-factor authentication (2FA/personal 2C). This will require you to enter your password and another form of verification, like a cellphone code. Even if passwords are hacked, it becomes far more difficult for unauthorised individuals to access email accounts. All of these safeguards work together to make email interactions more secure by fixing several possible weak spots.

2nd topic:

1: -Use encryption for sensitive emails and attachments. Consider using end-to-end encryption services or tools that connect with your email client to protect sensitive emails and files.

2: -Enable two-factor authentication on your email account. This adds an extra layer of security by requiring a second form of verification in addition to your password when you log in.

3: -Take care when sending information through email. Use email as a formal communication method, and avoid sending sensitive personal information like Social Security numbers or financial details via email.

In the realm of information technology, there is a vast array of methods and techniques utilised in computer crimes. To begin (1st), networks can be infiltrated by malicious software (malware), which can then steal data and disrupt operations. Secondly (2nd), phishing refers to the act of deceiving individuals into divulging sensitive information through the use of fraudulent emails or websites. According to Goodmans (2023), 3RD thirdly, botnets—networks of compromised computers that an attacker manages—are capable of launching massive assaults like Distributed Denial of Service (DDoS) that overload specific systems, 4th , keyloggers steal private information like passwords by covertly recording keystrokes. Ransomware encrypts victim data and demands payment to decrypt it, interrupting activities and finances (the fifth point). Finally, there’s cryptojacking, a piece of malware that stealthily mines cryptocurrency from a victim’s computer. Because these technologies may cause so much harm to people and companies when misused, stringent cybersecurity measures are required.

4th topic:

The facilitation or prevention of computer crimes is critically dependent on information technologies. For example, in the given text we have:

Malware: This evil program can be viruses, worms or ransomware that disrupts, damages or allows illegal entry into computers. A malware steals sensitive data, encrypts files for a ransom or creates backdoors to allow continuous unauthorized access.Phishing Tools: Tools Provided with phishing kits and phishing tools are used to create websites or emails that appear to be real ones in order to deceive individuals into providing their personal information such as usernames, passwords and credit card numbers. These tools automate the process of harvesting sensitive data from unsuspecting victims.Botnets: Computers that have been infected form network zombies which cybercriminals use to carry out large-scale attacks like Distributed Denial of Service (DDoS) attacks. Consequently, these attacks cause complete disruption or closure of a target’s systems.Keyloggers: Keylogging software/hardware tracks down everything the victim enters on his/her computer including passwords among other private information typed in by victim. Therefore, this data may be retrieved and utilized by criminals for purposes of accessing unauthorized systems or stealing one’s identity.

Hacking Tools: Hackers employ password crackers, vulnerabilities scanners as well as network sniffers among others useful in identifying weaknesses found within computer systems and networks which they target. By so doing, these tools capture data as it travels over networks through intercepting them; they decrypt encryptions containing passwords while also locate unsecured areas necessary for gaining unapproved access.

Social Engineering Techniques: Although not a technology itself, social engineering uses technology platforms such as social media and email to make people release their private information. So the techniques include pretexting, baiting and scareware which depend on psychological manipulation instead of technical exploits.

These IT technologies when abused can result in many forms of e-crime ranging from hacking into databases up to fraud hence there is need for robust cyber security measures and awareness to overcome these threats.
