Use Mac Address Filtering
Every network interface has a unique identifier known as a MAC address, regardless of whether its a computer, tablet, phone, or games console. The idea behind MAC address filtering is simple enough. You obtain the MAC addresses of your devices at home and enter them into the router so that only those unique identifiers are able to connect to your network.
Obviously, if you have a significant number of network capable devices this could take some time. But in theory you should be a lot more secure against a hacker in a car outside your house with a laptop perched on their knees. Unfortunately MAC addresses can be hacked and spoofed, so while the lesser hacker may give up the more determined one will simply bypass it. Think of MAC address filtering as putting a thorny rose bush up against the garden gate it may stop most opportunists from entering your garden, but those who really want to get in there will find a way.
Reasons Why You Were Hacked In The First Place
Hackers, like any criminals, are opportunists. Just like a shop window left open or a bag left unattended, some online activities leave you vulnerable to hacks.

Other Tips To Protect Computer Files And Folders
Because its difficult to set up foolproof file protection from a determined hacker, its smart to use redundant security protocols and other privacy tools when possible beyond a locked folder with encrypted files.
- Use a compression tool
You can archive sensitive files, compress them, and encrypt the contents with a required password.
- Install third-party software
- Back up important files
Even if something is protected with a password, it can still be deleted. Make sure to keep a backup of all your important files and folders.
- Keep track of passwords
Few things are worse than forgetting the password to an important document. Use a password manager to keep track of file and folder passwords. As an extra measure, make an unprotected archived copy of documents that you password protect. You can store them in a lockbox on a USB drive or external hard drive.
- Use anti-malware
Installing the extra protection of an antivirus or anti-malware program helps keep your whole system safe as well as individual files and folders.

Protecting Your Smart Tv From Hackers
Protecting Your Smart TV From Hackers
Youve likely heard plenty about the need to secure your computers, laptops, and mobile devices from hackers, viruses, and malware. But did you know that your smart TV also needs cybersecurity? Smart TV security is very important, because, without proper security protocols in place, savvy hackers can take advantage of vulnerabilities in the smart TVs operating system, enabling them to access your device and even take control of it.
The Benefits of a Smart TV
Smart TVs are dominating the consumer marketplace today, and its no big mystery why. Smart TVs allow you access to an enormous amount of content, both broadcast and through streaming apps. This enables you to truly enhance your entertainment options and view content that you might have otherwise needed a computer for previously.
Additionally, some smart TVs have further options for gaming, web browsing, storing photos and video, sharing content from mobile devices, and more. But this new technology, which is essentially an operating system much like a mobile device contains, is also vulnerable to hackers without proper smart TV security protocols in place.
Risks of a Vulnerable Smart TV
If you have a smart TV with Internet connectivity, then it is particularly vulnerable without IoT security. Hackers can exploit vulnerabilities in the operating system to access the information stored on your Smart TV and use it to perform a number of unscrupulous actions. These include:

You Didn’t Encrypt Your Hard Drive
If you hold sensitive data on your hard drive, it is important to encrypt it. That way, if you ever lose your laptop or someone steals your computer, they won’t be able to open the drive and access the information.
To encrypt your hard drive, press the Windows Key, type “This PC,” and open the app in the results. Right-click on the hard drive you want to encrypt and select Turn on BitLocker.
Select Use a password to unlock the drive, enter the password you wish to use and click Next. Make sure to create an unbreakable password you won’t forget. Then, choose how to back up your recovery key and click on Next.
Choose whether you want to encrypt only the disk space you’ve used or the entire drive, and then click Next.
Click Next to choose the default encryption mode.
Finally, click Start encrypting to begin the encryption process.
Once complete, there will be a lock icon on the encrypted hard drive. That means you’ll need to enter a password every time you restart Windows to gain access to your files.
Update Operating System And Software
Your anti-malware software is only as good as its last update. Make sure your protection software is set to update automatically. By doing this, your protection software always has the latest defenses against new hacks and malware without you having to remember to run a manual update routinely. Periodically check the date of your anti-malware definitions file to make sure that it is up to date.
In addition to anti-malware and anti-virus software, check to see if your operating system needs to be updated. Just as with anti-malware software, your operating system receives updates that thwart security weaknesses. The same goes for applications you use automatically updating these helps keep your software secure with little effort from you.

Password Protect Your Software And Lock Your Device
Most web-connected software that you install on your system requires login credentials. The most important thing here is not to use the same password across all applications. This makes it far too easy for someone to hack into all of your accounts and possibly steal your identity.
If youre having trouble remembering a whole bunch of passwords, then you could try a password manager. This will keep all of your passwords safe and you only have to remember one. A password can be combined with an email or SMS as part of a two-step verification method for extra security. 2SV usually kicks in when you log into a website or app from a new or unrecognized device requiring you to verify your identity with a PIN code.
While many security steps relate to intangible threats, there is always the possibility that someone could get their hands on your actual computer. A simple line of defence here is to have a strong computer password to at least make it more difficult for them to enter.
Other forms of verification include biometric methods like a fingerprint or retina scan. Alternative physical verification methods might involve key cards and fobs, such as those offered by Yubico. Any of these can be combined with each other and/or a password as part of a two-step authentication process.
