Section G: Long Answer Questions

When teaching a new student about online safety, I would emphasize the following important measures:

Never share personal information: They should never give out their full name, address, phone number, or school details to anyone online.

Keep privacy settings on: Encourage them to always enable and maintain the privacy settings on their web browsers and social media accounts to control who sees their information.

Use the Internet with adult supervision: They should always use the Internet in the presence of an elder, like a parent or guardian, especially when exploring new sites or communicating with others.

Do not share passwords: Stress that passwords should be kept secret and never shared with anyone, except for their parents or teachers if absolutely necessary for legitimate reasons.

Never meet online strangers: Advise them against meeting anyone they have only known online in person without their parents’ explicit permission and supervision.

Don’t respond to unknown messages: Teach them not to reply to unknown emails, messages, posts, or texts, as these could be scams or harmful content.

Cyber security is the process of protecting computer resources, such as networks, devices, programs, and data, from unauthorized access, damage, or attack. Cyber crimes are increasing around the world due to several reasons:

Increasing use of the Internet: As more people and businesses rely on the Internet for daily activities, the potential targets and opportunities for cyber criminals expand significantly.

Lack of awareness: Many Internet users are not fully aware of the risks and best practices for online safety, making them vulnerable to various cyber threats like phishing or malware.

Existing loopholes in software: Software programs, even those from reputable companies, can have vulnerabilities or ‘loopholes’ that cyber criminals exploit to gain unauthorized access or cause disruptions.

Untrained Internet users: A large number of users lack adequate training on how to identify and avoid cyber threats, which contributes to the success rate of cyber attacks.
