Описание: Welcome to “Security Threats: Validation and Device Usage.”

After watching this video, you will be able to: Explore device use best practices. Identify reputable driver and firmware sources, and list the do’s and don’ts of keeping your devices safe. To reduce security risks, always be sure to get your software, cloud services, device drivers, and firmware updates from legitimate sources like:

Vendor app stores – like Windows Store and Google Play Store. Authorized resellers – like Best Buy and Costco. Original Equipment Manufacturers (OEMs) – like Dell and Samsung. Software Manufacturers – like Adobe and Microsoft. If you’re downloading purchased software from a website, check the URL to ensure it begins with HTTPS. Click the lock icon in the URL bar to see if the certificate is still current and who owns it. Avoid pirated software torrents, they’re loaded with malware. Avoid software from untrusted sources. Avoid jailbreaking or rooting your phone. Non-approved apps are untested and could contain malware.

Original equipment manufacturers (or OEMs) provide drivers and firmware updates on their websites. Dell, HP, Samsung, Nikon, NVidia, and more all provide downloads for device drivers and firmware updates for the products they build and sell. Avoid 3rd party sites that claim to host drivers for the latest devices. These may be malware traps. There are some third-party sites that host legitimate obsolete drivers for obsolete hardware that a manufacturer no longer supports, but use these sites with care. Research them and check forum reviews to ensure they aren’t malicious.

Device driver software should also be digitally signed by the vendor, and the vendor's certificate should be trusted by your computer. Uninstall software that you don’t use or don’t want. New devices may come pre-loaded with unwanted trial software, commonly referred to as bloatware. Aging bloatware is soon outdated, and may have vulnerabilities. The same is true for software you no longer use. If you need an app in the future, download it from the software manufacturer’s website to ensure it is legitimate and up to date. Then enable automatic updates to keep the application safe. New attacks and malware are released onto the Internet daily.

This makes anti-malware, software, and VPN services a must for all your devices. Microsoft's Windows Defender protects your computer against viruses and malware, free of charge. It also integrates with the built-in firewall that comes with the Windows operating system and is enabled by default. However, Windows Defender does not perform VPN functions. Some third-party antivirus software such as McAfee, BitDefender, or Norton can be purchased for a reasonable cost if that is your preference. They may disable Windows Defender and Windows Firewall during their installation process, which is completely normal.

Many reputable antivirus companies provide malicious software removal tools for free, including Microsoft. They always have the latest virus signatures and are very effective. Just pick the one you like, download, and scan. It will automatically remove any malware it finds. If the tool doesn’t resolve your issues, you may need a PC technician who can assist you further. Prevent malware infection with safe computer usage and browsing techniques. Don't visit questionable websites or HTTP sites. Don't download from filesharing sites, as they have loads of viruses. Don't insert used or unknown disks, storage, or USB devices into your computer. Don't click links or file attachments from emails or messages – even if you know the sender.

Do use good anti-malware software on all of your devices and keep them up to date. Do use up-to-date firewall and VPN software on any devices you go online with. Do visit encrypted, HTTPS sites. Do use OEM or authorized reseller sites when downloading software. Do reduce accounts that have elevated privileges like admin, superuser, or root roles. In this video, you learned that: Apps, device drivers, and firmware should come from reputable sources. Rooting or jailbreaking makes devices vulnerable. Apps from filesharing sites are loaded with malware. Old apps and bloatware leave devices vulnerable. Malicious file removal tools are available for free from reputable antivirus companies, and automatic updates and antivirus, firewall, and VPN software keep devices safe.
