Q & A

What are some of the everyday activities that the internet enables?

The internet allows users to shop, book trips, watch movies, listen to music, manage banking, and even find social engagements.

How has the rapid development of the internet impacted the number of users?

The rapid development of the internet has led to a spectacular surge in the number of internet users, particularly those with high-speed connections via ADSL or cable.

What are the potential threats that come with the growing use of the internet?

The internet has brought a growing number of threats, including the misuse and abuse of the medium, with an alarming rate of increase in viruses, worms, and other malicious software.

How can viruses enter a computer without the user's knowledge?

Viruses can silently enter a computer through various means, often without the user's awareness, such as through email attachments or by exploiting leaks in computer programs.

How do viruses spread and multiply within a computer system?

Viruses can spread and multiply by accessing all the addresses in a user's mailbox and by exploiting vulnerabilities in the system to gain access and replicate.

What is the difference between a virus and a worm in the context of computer security?

While both are malicious software, a virus requires user action to spread, such as opening an infected attachment, whereas a worm can automatically exploit system vulnerabilities to propagate without user interaction.

What is a botnet and how does it operate?

A botnet is a network of computers infected with a bot, which allows a single malicious user to control multiple computers remotely, often to carry out criminal activities or distribute spam.

Why are bots considered more ruthless than other types of intruders?

Bots are considered more ruthless because they can take control of a computer without the owner's knowledge, turning it into a 'zombie' PC that can be used for criminal activities as part of a larger network.

What are the potential consequences of a botnet attack?

A botnet attack can have severe consequences, including the paralysis of a company's network or website, and the distribution of a large volume of spam, which can be more damaging than an attack from an individual PC.

How can users protect their computers from the threats mentioned in the script?

Users can protect their computers by following security best practices, such as installing antivirus software, keeping software up to date, being cautious with email attachments, and avoiding suspicious downloads.

What is the significance of the 'four simple rules' mentioned at the end of the script?

The 'four simple rules' are a set of guidelines that, when followed, can significantly reduce the risk of a computer being compromised by viruses, worms, bots, and other online threats.
