As more of our lives are based online, security against hackers is becoming more important. Hackers are focused on two things: creating chaos and taking money. Hackers steal personal information to make unauthorized charges on your accounts or disrupt your business using malware.

The good news is that there are a variety of ways to prevent cyberattacks, and most of them don’t require a large amount of effort. Start by encrypting data that’s not being transmitted over the internet (that includes social security numbers of employees or bank routing digits and other sensitive information). Turn on full-disk encryption tools which are available with the majority of operating systems: For PCs, it’s known as BitLocker and for Macs it’s FileVault.

Update your software frequently. Update your software program regularly. Many hackers gain access to computers by using outdated programs. Updates fix these vulnerabilities, making it harder for hackers to penetrate your system and steal information.

Install a firewall on all your devices. Firewalls are networks designed to manage the incoming and outgoing data that is stored on your computer. Windows and macOS both include built-in firewalls, but you should also install a third-party firewall program to safeguard your home networks and mobile devices.

Examine your device’s names as well as network names. Avoid using personal identifiers for your network such as your name or phone number. This can give hackers access to your information.

Be wary of discussing your work in public. Even the smallest details, such as the place where you grew up, or the names of your pets, can be used to help hackers break into security systems.
