Awareness of these issues and taking steps to safeguard against them should be a priority..

[Audio] Cybercrime is an ever-growing threat, with criminals pilfering money, goods, and personal data which can cause immense financial harm. They also target digital assets through various means, like spoofing, stealing identities, and phishing. It is imperative that we remain aware of the risks posed by these digital criminals, and strive to develop effective strategies to fight them..

[Audio] As the use of computers grows, the risk of theft has become ever more pressing. Laptops and smartphones are particularly easy to take, being able to be lifted from a room in a short amount of time. Their lightness and portability mean they can be hidden in a matter of moments, so steps must be taken to protect them. Securing devices with strong passwords and using secure storage for transportable options is of paramount importance..

[Audio] Never share confidential information with unknown individuals and protect yourself from social engineering and shoulder surfing techniques commonly used to gain unauthorized access to confidential data. Spoofing is a form of social engineering that targets unsuspecting victims to extract sensitive information, including passwords. Shoulder surfing is when someone looks over a victims shoulder to steal confidential data. Be aware of your surroundings to avoid a shoulder surfer..

[Audio] Phishing is a way for criminals to try and gain access to sensitive information - such as credit card numbers, passwords, or social security numbers - by pretending to be a legitimate company or organization in an electronic communication. An example of this would be criminals sending an email pretending to be from a popular bank and asking someone to fill in a fake bank web form. It is important to be aware of phishing attempts and to never give away confidential information to anyone you do not trust..

[Audio] Discussing the security risks posed by email, Whatsapp, and phishing, we will focus on the example of phishing and how it can be used to access personal information and accounts. It is vital to understand the risks, as well as how to reliably identify and repel attackers who utilize phishing techniques..

[Audio] Identity theft is a major threat to our security when using computers. It involves extracting personal information - such as national IDs, driving license numbers, and credit card numbers - to commit a crime in another person’s identity. With this sort of crime increasing, it is essential to know how to protect oneself from becoming a victim..

[Audio] When it comes to protecting your identity, taking a few simple steps can go a long way. Use a separate credit card for online purchases, only use secure websites with "https://" before the name, don't give out personal information over the phone, handle emails with caution, make copies of cards in case they are stolen, and notify authorities immediately if you become a victim of identity theft. These steps can help keep you safe..

[Audio] Malware and malicious software can cause immense harm to your computer. They can be employed to take confidential data, impede the performance of your computer, or even gain access to private computer networks. Instances of such software include viruses, worms, trojan horses and spyware. To guarantee your computer is guarded and secure from such malicious attacks, it is essential to take defensive measures..

[Audio] Talking about viruses, malicious programs that can damage or destroy computer data, tamper with your operating system, or display annoying pop-up messages, can be dangerous. They usually attach themselves to a file or program, and spread when files are exchanged via email attachments or flash drives. New types of viruses are now cross-platform, meaning they can affect any operating system, requiring users to take all the precautions they can to protect their computer and data..

[Audio] Worms are a type of malware, or malicious computer software, that can replicate themselves and spread across a computer network without the need of a host file.
