Q & A

What is computer security, and why is it important?

Computer security refers to the measures taken to protect computers and networks from unauthorized access, damage, or attacks. It is essential to ensure that data is kept safe and systems function optimally without interruptions, whether online or offline.

What are some common problems caused by internal factors in computer security?

Internal problems in computer security often include issues like virus infections, unauthorized access through software vulnerabilities, and the use of pirated software, which creates security holes. These issues can lead to data breaches and compromised privacy.

How can viruses spread in a computer system?

Viruses can spread through external devices like USB drives, or by downloading malicious files from the internet. Additionally, pirated software or unsafe online activities can expose systems to viral infections.

What is hacking, and how does it impact computer security?

Hacking refers to unauthorized access to computer systems or networks. It can compromise personal data, like email accounts and sensitive information, leading to privacy breaches or even financial loss.

How can clicking on illegal websites affect computer security?

Clicking on illegal or untrusted websites can expose a computer to malware, which can cause serious harm, such as system crashes or data theft. These sites may also lead to viruses being installed on the system.

What role do spam emails play in compromising computer security?

Spam emails often contain malicious links or attachments. Clicking on these links can direct users to harmful websites that may infect their systems with viruses or steal personal data.

What are some effective methods to protect against internal security threats?

To protect against internal threats, it is important to use reliable antivirus software, regularly update passwords, and avoid using pirated software. Additionally, installing anti-malware tools and ensuring security updates are performed regularly can help mitigate risks.

What are the dangers of sharing passwords with others?

Sharing passwords, especially with untrusted individuals, increases the risk of unauthorized access to your accounts. This can lead to identity theft, data loss, or unauthorized financial transactions.

How does using USB devices affect computer security?

USB devices can be a significant security risk, as they can carry viruses or malware. When connected to a computer, they may introduce harmful programs that compromise system integrity or steal data.

What steps should be taken to protect against external security threats?

To protect against external threats, one should avoid sharing passwords, be cautious about lending or borrowing devices, use USB protection, and ensure that all security software is up to date to defend against potential breaches from external sources.
