Health Safety and Security at Workplace

Two-step verification adds a second proof of identity, such as a code or authentication device, but it does not replace the password. A strong, unique password makes the first barrier harder to break and reduces damage if another service is compromised. Using both protections is stronger than relying on either one alone.

Checking the recipient’s name or identifier and the amount before confirming helps ensure that money goes to the intended person for the intended value. It can reveal a wrong account, altered payment request, or typing mistake before the transaction becomes difficult to reverse. The check protects the transaction; it does not affect computer hardware.

Public Wi-Fi may be poorly configured, monitored, or impersonated, so banking credentials and transaction information can face additional exposure. The safest choice is to postpone sensitive banking or use a trusted private network or a protected mobile connection. Public Wi-Fi is not automatically dangerous in every case, but it is not a suitable default for sensitive transactions.

Deleting a post from one account or platform does not guarantee that every copy disappears. People may have viewed it, taken a screenshot, downloaded it, forwarded it, or recorded it before deletion. Search caches or platform backups may also persist for some time. This lasting possibility is why users should consider the digital footprint before posting.

Good ergonomics combines an upright, supported posture with a comfortable viewing distance, suitable screen height, and regular short breaks. These habits can reduce eye strain, neck and back discomfort, and fatigue during extended use. Sitting very close, ignoring chair adjustment, or working continuously increases physical strain rather than preventing it.

Public places can contain imitation or unsafe Wi-Fi networks with names resembling the genuine network. Confirm the exact network name with staff or another trusted source before connecting. Connecting randomly, exposing a password, or opening accounts on every network increases the chance of data theft.

Both wired and wireless networks transmit data and may allow access to shared devices or files. Therefore, both can require authentication, permissions, secure configuration, and protection from unauthorized access. Wireless connections may be exposed through radio signals, but wired networks are not automatically safe or permission-free.

Local storage is kept on a device, so device locks, user permissions, malware protection, and backups are important. Cloud storage is accessed through an account and service, so strong authentication, permissions, and safe sharing are important. Both forms still need protection; neither is automatically secure.

Cloud storage permits access from different locations, so anyone who obtains the account credentials may reach the file. A strong unique password and an additional verification method reduce unauthorized access. Sharing the account or using an easy password weakens protection, while an unnamed file does not secure the account.

Unknown files may contain malware, and outdated antivirus software may lack current detection rules for newer threats. Opening such files combines unsafe behavior with weaker protection, increasing the chance of infection or data damage. Update security software, scan files, and open attachments only when their source is trusted.

Slowness, unexpected messages, and applications opening without permission can indicate malware or another security problem, although they are not proof by themselves. A security scan and professional or administrator help are safer first steps. Clicking messages, sharing passwords, or deleting everything blindly can worsen the situation or destroy evidence.

Reusing one password creates a chain of risk. If a criminal obtains it from one service, they may try the same password on email, cloud storage, and payment accounts. Separate strong passwords, preferably managed by a trusted password manager, limit the damage when one account or service is compromised.

Two-step verification adds another check after or alongside the password; it does not replace the need for a secure password. A strong unique password makes guessing and credential attacks harder, while the second factor provides additional protection if the password is exposed. Together they form stronger layered security.

A payment PIN, one-time code, or similar secret should not be disclosed to an unsolicited caller. The caller may be impersonating a bank or service and using urgency to obtain access. End the call, use the institution's official app or published contact number, and verify the issue without revealing the secret.

Checking the recipient name, amount, and identifying details helps confirm that the payment is going to the intended person or account. It can reveal a wrong account, altered request, or impersonation before money is sent. These checks do not affect the mouse, document colour, or computer shutdown.

Public Wi-Fi is shared and may be fake, poorly protected, or monitored by attackers. Banking involves highly sensitive credentials and financial information, so it is safer to wait for a trusted private network or use a properly secured connection. Public Wi-Fi is not always dangerous, but its uncertain trust makes sensitive banking a poor choice.

Documents visible behind a participant may expose names, account details, grades, or other confidential information to meeting members or anyone recording the session. Changing the background, moving the documents, or turning off the camera removes the exposure. Sharing the documents or speaking a password would increase the privacy and security risk.

A balanced workstation keeps the body supported, places the screen at a comfortable distance and height, and includes brief regular breaks. These habits can reduce eye fatigue and strain on the neck, shoulders, back, and wrists. Sitting very close, working continuously, or ignoring chair height increases discomfort rather than preventing it.

Urgency and fear are often used to encourage people to forward misinformation before they check it. Look for the original source, date, supporting evidence, and confirmation from reliable independent sources. Do not forward an unverified claim or reveal personal information. Fact-checking protects both the recipient and the wider community.

Reply All sends the response to the original sender and the other recipients listed in the message. If the reply contains private information, it may be disclosed to people who did not need to receive it. Check the recipient list before sending and use Reply when the response is intended only for the sender.

A secure connection indicator usually describes encryption between the browser and the website; it does not prove that the site or every request is trustworthy. An unexpected password request for a free certificate is suspicious and may be phishing. The user should stop, check the official domain and purpose through an independent route, and avoid entering or sharing credentials. Therefore, C is correct.

An unknown file may contain malware, especially when it comes from an untrusted source. Outdated antivirus software may lack the latest signatures or detection improvements, so it can miss newer threats. Opening such files combines unsafe behavior with weaker protection and therefore increases infection risk. Updating security software and avoiding suspicious files are both sensible precautions.

Unexpected slowness, unknown messages, and applications opening by themselves can indicate malware or another security problem, although they are not proof by themselves. A security scan and trusted technical help are sensible first steps. Clicking messages, sharing passwords, or deleting everything blindly can worsen the situation or destroy useful evidence.

Public Wi-Fi is shared and its security may be unknown; a fake hotspot or poorly protected network can expose sensitive activity. Banking should preferably be done through a trusted private network or mobile data, with secure site and account protections. Public Wi-Fi is not automatically dangerous for every task, but sensitive banking is best avoided on it.

A browser security indicator generally describes how the connection is encrypted; it does not prove that the website owner or request is trustworthy. An unexpected password request related to a scholarship may be phishing. The student should stop, avoid entering credentials, and verify through an official channel, so C is correct.
