Is Your Computer Secure? Protect Your Privacy Online
If you're using a computer that isn't properly secured, identity thieves and other fraudsters could access and steal your personal information. Fortunately, there are safety measures and best practices you can implement to protect your computer devices, your privacy, and the security of your family. Below are essential tips to help reduce your risk while navigating the online world.
1. Install a Firewall
A firewall is a software program or piece of hardware designed to block hackers from gaining unauthorized access to your computer. Hackers often scan the Internet in search of vulnerable systems, similar to how telemarketers make random calls. They "ping" thousands of computers and wait for responses. A firewall blocks these incoming "calls" from untrusted sources. This is crucial for users with high-speed Internet connections like DSL or cable.
Many operating systems come with built-in firewalls that may be deactivated by default. Be sure to activate and configure your firewall to protect your system. Make sure to keep it updated and consult your operating system’s Help feature for detailed setup instructions.
2. Use Anti-Virus Software
Anti-virus software is essential for protecting your computer from harmful viruses that can destroy data, cause system crashes, and allow hackers to misuse your email account. This software scans your system and incoming emails for viruses, quarantining or deleting any it detects. Keep your anti-virus software updated to combat the latest threats. Many programs offer automatic updates and real-time scanning features, ensuring that your system remains protected.
Make it a habit to run a thorough virus scan at least twice a month.
3. Use Anti-Spyware Software
Spyware is hidden software that tracks your online activities and can gather sensitive personal information. It may include keyloggers that record everything you type, such as passwords and financial details. Signs of spyware infection include an increase in pop-up ads, slow system performance, or being redirected to unwanted websites.
Some anti-virus programs include spyware protection. Be sure to activate this feature or consider installing dedicated anti-spyware software. Keep your spyware protection software up to date and run regular scans. To prevent infection, avoid downloading software from untrusted sites and refrain from clicking on links in spam emails or pop-up windows.
4. Manage Your System and Browser to Protect Your Privacy
Operating systems and browsers frequently release updates that address security vulnerabilities. To ensure your system is protected, set your system and browser’s security settings to medium or higher. Enable automatic updates wherever possible, and make use of services like Windows Update for Windows users or automatic updates for Mac systems.
5. Secure Your Wireless Network
If you’re using a wireless network at home, it’s vital to take precautions to prevent unauthorized access. Start by enabling encryption on your wireless router. WPA encryption is more secure than the older WEP. Ensure that all devices, including your computer and router, use the same encryption method. Avoid using default passwords or network names (SSIDs), as hackers are familiar with these. Change your router’s pre-set passwords and identifiers to something unique. When you’re not using your wireless network, turn it off to further reduce the risk of intrusion.
Remember, public Wi-Fi networks, or "hot spots," may not be secure. Always avoid accessing or transmitting sensitive personal data over these networks.
6. Be Cautious with File Sharing
Sharing digital files—whether music, movies, or software—can be convenient, but it also comes with risks. File-sharing programs connect you to networks of other computers, making it easy for others to download files from your system. File-sharing can expose your computer to viruses and spyware. Additionally, downloading illegal or copyright-protected material can lead to legal consequences.
If you choose to share files, be selective about the networks you connect to and avoid downloading suspicious files.
7. Use Strong Passwords and a Password Manager
Using the same passwords across multiple accounts might seem easier, but it also makes it simpler for hackers to access your personal information. Start using strong, unique passwords for each account. A password manager can help you create and store secure passwords. These tools generate complex, random passwords and encrypt them, so you only need to remember one master password.
Some free password managers include KeePass and Password Safe, while paid options like Keeper allow you to sync passwords across multiple devices.
Protect your password manager with a passphrase that is both memorable and difficult to guess. Avoid using easily guessed phrases, and make sure your passphrase is unique to you.
