<prompt> Hlalosa hore na tsamaiso ea Unix e ka sireletsoa joang litšokelong tsa ka ntle.nan  <response>: Instruction in English: Explain how a Unix system can be protected from external threats. . Response in English: A Unix system can be protected from external threats using a number of techniques and measures. These include:1. Updating regularly: Keeping the system updated with the latest patches and upgrades is crucial for closing security holes and fixing vulnerabilities.2. Firewall: Configuring a firewall to restrict incoming traffic to the system can provide protection against intrusion and unauthorized access. Only the ports and services required for the systems functionality should be open in the firewall settings.3. Password policies: Enforcing strong password policies, including the use of complex, unique passwords and frequent password changes, can help prevent unauthorized access to the system.4. User Management: Care should be taken when creating user accounts and assigning permissions. Unnecessary accounts with high levels of access should be avoided and the principle of least privilege should be followed users should only have the minimum level of access needed to perform their job.5. Anti-virus software: Installing an anti-virus program and keeping it updated can help protect against malware and viruses.6. Monitoring logs: Keeping an eye on system logs and monitoring for unusual activity can help to detect and prevent external threats. Auditing tools can be used to automate the process.7. Backups: Regular backups of important data should be taken to ensure that the data can be restored in case the system is compromised.8. Encryption: Using encryption for transmitting and storing sensitive data can help to prevent unauthorized access.9. Network security: The systems network should be secured, with measures such as wireless encryption, Virtual Private Networks VPN and secure connections SSH.10. Physical security: Finally, physical security of the system equipment can prevent unauthorized access to the system, and security measures such as camera surveillance and alarm systems can help monitor any attempts at breach.By adopting these measures, a Unix system can be made more secure against external threats. However, security is an ongoing process that requires constant vigilance and regular attention to keep the system safe. . Response in Sesotho: Sistimi ea Unix e ka sireletsoa litšokelong tsa kantle ho sebelisoa mekhoa le mehato e mengata. Tsena li kenyelletsa: 1.
