5,Explain the most common controls to protect computers from risks?

The most common controls to protect computers from risks include:

1. Antivirus Software: Installing and regularly updating antivirus software helps detect and remove malware, viruses, and other malicious programs that could harm the computer.

2. Firewalls: Firewalls act as a barrier between a computer and the internet, monitoring and controlling incoming and outgoing network traffic. They help prevent unauthorized access to the system and protect against network attacks.

3. Strong Passwords: Using strong and unique passwords for user accounts can prevent unauthorized access. Passwords should be complex, containing a combination of letters, numbers, and special characters.

4. Software Updates: Regularly updating operating systems, applications, and software is crucial to ensure that any security vulnerabilities or bugs are patched. This helps protect the computer from exploitation by attackers.

5. User Education: Educating users about best practices for computer safety and security is essential. This includes teaching them about phishing emails, not clicking suspicious links, downloading files from trusted sources, and being cautious while browsing the internet.

6. Backup and Recovery: Regularly backing up important data and files on external hard drives, cloud storage, or other devices helps protect against data loss caused by hardware failure, malware, or other risks. Additionally, having a disaster recovery plan in place ensures that the system can be restored quickly in case of an incident.

7. Limited Access and User Privileges: Granting users the minimum necessary access rights and privileges reduces the risk of unauthorized access and limits the potential damage caused by any malicious activity.

8. Secure Wi-Fi: Securing the home or office Wi-Fi network with WPA2 or WPA3 encryption, changing default passwords, and disabling remote management reduces the risk of unauthorized access to the network and keeps sensitive data secure.

9. Web Filtering: Implementing web filtering controls helps block access to known malicious websites, phishing sites, or other harmful content. It prevents users from inadvertently visiting sites that could compromise computer security.

10. Physical Security: Taking physical measures like locking computers when not in use, securing servers in locked rooms, and using cable locks for laptops can prevent unauthorized physical access and theft of data.

It is important to note that while these controls are effective, a layered approach that combines multiple controls provides greater protection against risks.

Step 1: Installing Antivirus Software

One of the most common controls to protect computers from risks is installing antivirus software. This software is designed to detect and remove malicious software, such as viruses, worms, and trojans. Antivirus software regularly scans your computer for any signs of these threats and alerts you to take action.

Step 2: Keeping Software Up to Date
Keeping all software, including the operating system and applications, up to date is crucial. Developers regularly release updates and patches to fix security vulnerabilities and bugs that may be exploited by hackers. Enabling automatic updates ensures that you are always using the latest, most secure versions of the software.

Step 3: Using Strong Passwords
Using strong and unique passwords acts as a barrier against unauthorized access to your computer. A strong password usually contains a combination of upper and lower case letters, numbers, and special characters. It is important to avoid using common passwords and to avoid reusing passwords across different platforms or accounts.

Step 4: Enabling Firewall Protection
Firewalls act as a barrier between your computer and the internet, controlling which connections are allowed and preventing unauthorized access. It is recommended to enable the built-in firewall on your computer or use a third-party firewall software for added protection.

Step 5: Regularly Backing Up Data
Regularly backing up your data is another essential step to protect your computer. It ensures that you have a copy of your important files and documents in case of data loss due to hardware failure, malware, or other risks. You can use external hard drives, cloud storage, or other backup solutions to secure your data.

Step 6: Educating Yourself on Phishing Attacks
Phishing attacks are one of the most common methods used by cybercriminals to gain access to sensitive information. Educating yourself about phishing techniques and how to recognize suspicious emails, links, and attachments can help you prevent falling victim to such attacks. Be cautious when sharing personal information online and be skeptical of unsolicited emails or messages.

By following these common controls, you can significantly reduce the risks and vulnerabilities associated with computer use and enhance the security of your devices.

To protect computers from risks, there are several common controls that can be implemented. Here are some of the most important controls:

1. Antivirus Software: Install up-to-date antivirus software on your computer. This software scans for and removes malicious software like viruses, worms, and Trojans, protecting your computer from getting infected.

2. Firewalls: Enable and configure a firewall on your computer. Firewalls act as a barrier, monitoring incoming and outgoing network traffic, and blocking unauthorized access. They help prevent hackers and malicious software from gaining access to your system.

3. Regular Software Updates: Keep your operating system, web browsers, and other software up to date. Companies release updates to fix security vulnerabilities and bugs, so regularly installing these updates will help protect your computer.

4. Strong Passwords: Use strong, unique passwords for all your accounts. A strong password should contain a mix of upper and lowercase letters, numbers, and special characters. Avoid using easily guessable information, like your name or birthdate.

5. User Account Management: Limit the number of accounts with administrative privileges on your computer. Use a standard user account for day-to-day activities, and only use an administrative account when necessary. This helps minimize the risk of malware or unauthorized changes.

6. Backup and Recovery: Regularly back up all your important data and files. In the event of a system failure or data loss due to malware or other issues, having backups will help you recover your files.

7. Phishing Awareness: Be cautious while opening emails, downloading attachments, or clicking on links from unknown sources. Phishing emails can trick you into revealing sensitive information or installing malware. Use an email spam filter and be vigilant about suspicious messages.

8. Secure Wi-Fi Connections: Ensure that your Wi-Fi network is encrypted and protected with a strong password. Avoid connecting to public Wi-Fi networks, as they may not be secure and can be exploited by attackers.

It is important to note that these controls are not exhaustive and should be supplemented with other security measures depending on the specific requirements and risks faced by your computer. Regularly educating yourself about current threats and best practices for computer security is also crucial in maintaining a secure computing environment.
