Steps

Secure your account

Generate complex passwords. Passwords used to access your accounts on apps or websites should include multiple numbers, a combination of lowercase and uppercase letters, and special characters that are hard to guess.

  • Do not use the same password for more than one website or account. This helps minimize damage to you if a hacker gets hold of one of your passwords. [1] X Research Source
Use a password manager. A password manager that stores and autofills information for you across multiple sites, allowing you to create unique and complex passwords for each site without having to worry about typing passwords. password many times. While it’s obvious that you should also protect your own passwords, a password manager will make your device more secure.

  • Some of the highly rated third-party password managers include “Dashlane 4”, “LastPass 4.0 Premium”, “Sticky Password Premium”, and “LogMeOnce Ultimate”.
  • Most browsers have a built-in password manager to store and encrypt your passwords.

Do not reveal passwords. This advice may sound obvious, but it’s worth repeating: With the exception of a few school services, you should not and are not obligated to provide a password to a site’s administrator for access. your account. [2] X Research Source

  • This logic also applies to people in the information technology industry, representatives of Microsoft or Apple.
  • Likewise, don’t reveal your tablet or phone’s password or PIN to others. Even your friends may accidentally reveal that password.
  • If you are forced to give your password to someone else for some reason, you should change it as soon as they’ve done what they need to do with your account.

Change your password regularly. In addition to keeping passwords private, you should change passwords across multiple accounts and devices at least every six months.

  • Make sure not to use the same password twice (for example, your Facebook password should be different from your bank account…).
  • When changing your password, you should change it completely. Don’t just replace a letter with another number.
Use two-factor authentication. This method requires you to enter a code sent to you via text message or other service to access your account after typing your username and password. This makes it harder for hackers to steal your information even if they already know your password.

  • Most major websites including popular social networks have two-factor authentication built in. Check your account settings for how to enable this feature.
  • You are allowed to set up two-factor authentication for your Google account.
  • Some popular applications that have the ability to receive text messages are Google Authenticator and Microsoft Authenticator.
Read the privacy policy carefully. Any company that owns your information should have a privacy policy that outlines how it will use it, and to what extent it will be shared with others. [3] X Research Sources

  • Many people have the habit of clicking agree to the privacy policy without even reading it. If you find it a bit tedious to read carefully, you should at least skim it to get a glimpse of how your data will be used.
  • If you don’t agree with something in the privacy policy or don’t feel comfortable, you may need to reconsider sharing information with that company.

Make sure you type the password into the official website. There are many types of scams out there, like a malicious website posing as a login page to a social network or bank account – which is one of the simplest ways to hack your account. One way to spot a fake site is to look at its URL: If it looks close to (but isn’t) the URL of a trusted site (seeing “Faecbook” instead of “Facebook” for example), it’s a fake site. fake. [4] X Research Sources

  • Example: You should only fill in your Twitter login information on the official Twitter page. Don’t do this on another page that requires login information to share an article or something like that.
  • The only exception is when a university uses an available service (like Gmail) through their homepage.

Secure your phone

Change your phone password regularly. The first step in fighting bad guys trying to see or steal your data is to set passwords that are hard to guess and change them often.

  • Make sure that you change to a completely new password each time — Don’t just change some of the password.
  • On most phones, you can set a “complex” or “advanced” password that includes both letters and characters in addition to the usual numeric characters.
Use Touch ID if possible. While you may still need to set a password for your phone’s lock screen, it’s recommended that you use Touch ID on any supported device to pay for many other things and services that are available.

  • As always, it’s always a good idea to reduce password typing time on any platform.
Browse with a secure web application. While third-party browsers like Tor or Dpphin may seem tempting, syncing your Google Chrome or Safari account with your phone and computer saves you the trouble of retyping your saved passwords and keeps them safe. Secure your device from unsafe websites.

Update equipment and software in a timely manner. As soon as an update is available for something, from the Facebook app on your phone to the entire operating system, you should update it as soon as you can.

  • Many updates are patches that fix weaknesses and address security issues. If the software is not updated in time, the device’s weaknesses can be exploited and become the target of attacks.
  • Take advantage of automatic download of all updates if available. You will avoid a lot of trouble.

Charge your phone at reliable USB ports. This includes USB ports on your computer and in your car (if available). Public USB ports, like those you see in coffee shops, can expose your information.

  • For this reason, it’s a good idea to take the power connector and USB cable with you if you’re traveling.
Avoid jailbreaking (or rooting) your phone or using unorthodox apps. Both iPhone and Android have a layer of security that can be broken by jailbreaking or rooting their respective devices, but doing so makes your phone more vulnerable to attacks and infections, which was previously impossible. Similarly, downloading apps from unknown sources (aka “side-loading” apps) significantly increases your risk of getting infected with malware.

  • Android phones have built-in security tools that prevent downloading apps from unknown sources. If you choose to disable this feature (from the Security tab in Settings), you need to carefully check the website containing the application to be downloaded before proceeding with the download.

Secure your computer

Hard drive encryption. If your hard drive is encrypted, a hacker won’t be able to read the data stored on it, even if he gains access to your hard drive. Although you have taken many steps to prevent access, encryption is another method to help keep your information secure.

  • For Mac – FileVault is an encryption feature for Mac. You can enable this feature by clicking the apple icon in the upper-left corner of your Mac screen, clicking System Preferences , clicking the Security & Privacy icon , clicking the FileVault tab , then clicking Turn On FileVault . You may have to click the lock icon first, then type in the password for the administrator account on the Mac. [5] X Research Sources
  • For Windows – BitLocker is Windows’ default encryption feature. To enable this feature, simply type “bitlocker” into the Start search bar, click the “Bitlocker Drive Encryption” option, and then click Turn on BitLocker . Remember that Windows 10 Home users do not have access to BitLocker without updating to Windows 10 Pro.

Install updates as soon as they are available. In addition to improving performance, system updates often improve security. [6] X Research Sources
Regularly back up data. No matter how good the layer of security is, there is a chance that your data will be exposed. The reason could be a hack, or simply a computer error. Backing up your data helps ensure that you don’t lose anything.

  • There are many cloud services that you can use to back up your data. Double-check the security of these services before using them. Although you may be tempted by the most affordable service, you still want to make sure that your data is kept safe.
  • You can also use an encrypted external hard drive for data backup. Set up your computer to automatically back up every day, when you don’t normally use it.
Don’t click on suspicious links or reply to strange emails. If you receive a strange email, or an email from a sender you don’t know, consider it a hacking conspiracy of the bad guys. Avoid clicking on any links or giving personal information to the sender.

  • Remember that simply replying to an email is enough to let the sender know that your email address is valid and in use. Although you may think of replying in a sarcastic fashion, you should know that this gives the bad guys the information they need to hack your account.
Install or enable a firewall. Both Windows and Mac computers have firewalls that help prevent hackers from gaining access to your computer. However, on most computers, the firewall is not turned on by default.

  • Go to your computer’s security settings and navigate to the “firewall” setting. Here, make sure that the firewall is turned on and is blocking connections from outside.
  • If you’re using a wireless network, your router should also have a firewall.
Allow firmware password. If your computer has this option available, ask the user for a password before rebooting from the drive or entering single-user mode. Hackers usually can’t get the firmware password, unless they already have access to your computer. However, you must be very careful, not to forget or lose the password because it is very difficult to get it back. The way to generate the firmware password is as follows:

  • On Mac – Restart your Mac, then hold down the ⌘ Command and R keys as it boots up. Click Utilities , click Firmware Password Utility , click Turn On Firmware Password , then create your password.
  • On Windows – Restart your computer and then hold down the BIOS key (usually Esc , F1 , F2 , F8 , F10 , or Del ) as the computer boots. Use the arrow keys to select the password option, then type the desired password.
Turn off remote access. Although sometimes you need to access your computer remotely, or allow someone to do this (for example, when you need technical support), it’s usually a good idea to turn this feature off, only turning it on once. whenever needed.

  • Allowing remote access means leaving the door open, making it easier for hackers to break into your computer and steal your data.
Install anti-virus software on your computer. Antivirus software has the ability to identify and remove potentially harmful programs and files as soon as they are downloaded. Windows Defender is a good piece of software for personal computer users, and it comes pre-installed on computers running Windows 10. If you’re using a Mac, AVG or McAfee software can become “” defenses” solid, support for the default security suite Gatekeeper. [7] X Research Sources

  • You should also make sure that your computer’s firewall and Bluetooth feature allow only trusted connections to access your computer.

Use secure wireless networks. In general, a secure network will ask you to enter a password before connecting. In some places (like airports or coffee shops) you’re allowed to ask for a password after buying something.

  • If the wireless network is not secure, the computer will notify you before connecting. Some operating systems even display an exclamation mark next to the name of the network.
  • If you need to use the Internet but do not have access to a secure network, you need to change your password the next time you log in to a secure network.
  • If you have a wireless network at home, make sure it is always secure and encrypted. Remember that by default, wireless routers are usually not secure – you have to set them up yourself.

Only download programs from trusted sites. You should also keep this in mind when visiting websites using an unsecured connection. If you don’t see a lock icon to the left of the URL and “HTTPS” in front of the “www” part of the URL, it’s best to avoid visiting the site (or downloading anything) entirely if possible. .
Learn to recognize fake websites. In addition to avoiding sites that don’t have “HTTPS” and a lock icon next to the URL, you should double-check the site’s URL before typing your password on it. Some sites conspire to steal login information by spoofing websites (also known as “phishing”). You can identify these pages by looking for extra (or missing) characters, hyphens between words, or extra symbols.

  • For example, a fake Facebook page might have a URL of faceboook.com .
  • Sites that have hyphens in their names (between “www” and “.com”) are often unreliable.
Do not use file sharing services. Often, sharing files not only violates intellectual property laws, but file-sharing websites can sometimes even eat with hackers. You might think you’re downloading a recent hit song or a new movie, but the file is actually a virus or malware in disguise.

  • Many files are cleverly designed so that the virus or malware hidden within is not detected by virus scanning software. The virus will not harm the system unless you try to open the file.
Shop only on secure sites. Never enter account or credit card information on a page that doesn’t have “https://” in front of the “www” part of the website address. The letter “s” ensures that the site is secure. A page without that text will not encrypt or protect your data.
  • Do not disclose personal information on social networks. You may think you’re only sharing with friends, but revealing too much information about yourself and your life on social media can leave you vulnerable to hackers. You should share personal information directly with people who want to know instead of posting publicly on social networks. [8] X Research Sources
  • Advice

    • There are many free and paid firewalls and antivirus software on the Internet for you to choose from.
    • Make sure your password is not the same as your username or email.

    Warning

    • Unfortunately, the only way to be completely secure and never get hacked is to stay away from technology altogether.
