    There are several steps you can take to protect your network from hackers:

     Simple hacker-protection tips for your computer and other devices

    Phishing, ransomware, Trojan horses… We live in a world where cyber threats are increasing in number and sophistication. Data theft, reputational harm, extortion, espionage, and data destruction, to name a few. We can no longer ignore the dangers we face daily. You must take precautions to protect your computer from hackers. We’ve compiled a list of essential tips to help you learn how to protect and keep your devices safe. Don’t worry you don’t have to be a cybersecurity expert to comprehend what our secure hacks entail.

    How to keep hackers out of your computer, smartphone, or tablet

    First and foremost, we want to emphasize the significance of physical security for your devices. When you are not using your computer or smartphone, lock it! The first line of defense is to never leave your device unattended. Disable lock-screen notifications and Bluetooth as well. Thieves could exploit them to gain access to your device’s system. Protecting your device from physical theft is just as important as the following suggestions.

    Connect to a Secure Network

    Being connected to the Internet may allow attackers to gain access to your computer. So, use SSL/TLS to connect to all websites, and harden and secure devices that come with overly permissive factory-default configurations, such as IoT devices, routers, and so on.

    Configure and Enable a Firewall

    A firewall, like a router, controls the flow of information between your computer and the Internet. It creates a gateway to prevent the disclosure of your data. It will also notify you if malicious individuals attempt to gain access to your computer system.

    Most home routers, as well as most operating systems (Windows and macOS), include a built-in firewall. This means you shouldn’t have to worry about installing one because your device is already secure. However, you can improve your computer security by creating a strong password that will prevent any attempt to disable your firewall (Check your Wi-Fi operator guidelines for more information).

    Use anti-virus and anti-spyware software.

    Installing antivirus software and keeping it up to date are critical steps in computer security. Install an antivirus app on your phone as well. Ensure that you keep them current.

    However, antivirus is not a magical tool that can eliminate all threats. This software is based on a database of previously identified malware, which is kept in an internal registry (most often, antivirus updates aim to add new entries – i.e., newly discovered viruses – to this registry).

    This means that they are unable to detect new malware. So, keep in mind that using an antivirus is not a panacea. It will not exempt you from taking additional precautions.

    Spyware is malicious software that is designed to monitor your employees’ computer activities to gather information useful for data theft. The software is designed to spy on the company to obtain sensitive information such as patents or contracts.

    Most antivirus tools from major cybersecurity companies include anti-spyware. If this isn’t the case with you, get one to keep hackers from stealing your data.

    Remove Unwanted Software

    Intruders can compromise your computer by exploiting software flaws. As a result, the less software you have, the more secure your computer will be. Remove any unnecessary software only after confirming that it is safe to do so. Similarly, disable non-essential services and cancel unnecessary default features to eliminate multiple attack vectors.

    Keep up with the PoLP (Principle of Least Privilege)

    In most cases of malware infection, the malware can only operate with the rights of the logged-in user.

    Consider having two types of user accounts to protect your device and reduce the impact of malware if it successfully infects your computer:

    • A basic account with the bare necessities for day-to-day operations;
    • When you need to install or remove software or change system settings on your computer, you’ll need to log in as an administrator.

    Typically, web browsers installed on new computers do not have secure default settings. As a result, securing your browser is an important step in improving the security of your computer, as more and more attacks target web browsers. Use a reputable search engine (why not DuckDuckGo?) and stay away from unnecessary plugins/add-ons.

    Use a Secure Web Browser

    Web browsers installed on new computers do not typically have secure default settings. As a result, as more and more attacks target web browsers, securing your browser is an important step in improving the security of your computer. Use a reputable search engine (DuckDuckGo, for example). and avoid unnecessary plugins/add-ons.

    Firmware can also contain vulnerabilities. A firmware is a piece of utility software that allows your devices to perform additional functions (such as allowing your device to connect to any type of printer, or to support a microphone or headphones).

    Enable automatic updates whenever possible to avoid having to think about them.

    Use Best Security Practices

    • Only create strong and unique passwords

      The password is the first line of defense against intrusions, as well as the least expensive and easiest to set up tool for protecting your device. However, this will only work if you follow a few simple rules. More password advice can be found in this article on password best practices.

    • Watch out for ransomware and phishing attacks

      Education is the best line of defense against phishing and ransomware attacks, as well as stopping hackers on your computer. Learn how to recognize and avoid social engineering techniques by reading our articles on phishing, spear phishing, whaling, smishing, and vishing. Spread the word about our email security and privacy awareness course!

    • Make use of two-factor authentication

      Two-factor authentication (or 2FA) serves as an additional layer of security after your password. Many websites will offer to use it to secure your account and limit your access to them. Sure, 2FA adds some latency to your connection, but the benefits outweigh the drawbacks.

    Do Not Use Illegal Software

    It may jeopardize your data and computer security, as well as violate the law.

    Keep a Backup

    Depending on the volume of computing activities, use backup software to schedule multiple backups per week. Include in your backup perimeter all devices and software you use, and make at least two copies:

    • The first is on an external hard drive (hard disc, USB key, NAS, etc.).
    • Another is on a cloud storage platform, such as Mailfence documents.

    You could ideally add a third one on another external hard drive to be stored externally to protect your files from any disaster that may strike your home or business.

    Additional security tips for your computer and other devices.

    Create a Disaster Recovery Plan

    What would you do if your company was hit by a disaster tomorrow (for example, a fire or a ransomware attack)? Are you prepared for this type of scenario? Do you know exactly what you need to do to avoid further damage and restart your business despite data loss or equipment destruction?

    If you’re unsure how to answer this important question, consider creating your disaster recovery plan. You’ll be grateful to have a to-do list amid the chaos to contain the risks, repair the damage, and reactivate what can be restored.

    This type of program cannot be improvised, and you may require the assistance of an IT specialist to set it up and test its validity.

    Encrypt your information

    Encryption is the process of scrambling data and messages using a mathematical key. The user will need to know this key to decipher the data or message. This system protects all data by rendering it unreadable, ensuring that it remains private. It is an effective method of preventing interception for espionage and data theft.

    You can also use a virtual private network to encrypt your web traffic (VPN). It will encrypt your data before sending it so that no one can read it while it is in transit. Only at its destination (the website/software with which you are communicating) will the relevant data be deciphered.

    Furthermore, a website that uses SSL/TLS will encrypt the data you exchange with it, making it impossible for malicious individuals to intercept it. You can identify these websites by the padlock that appears in your browser’s search bar when you are connected to them. By activating the HTTPS Everywhere extension, you can ensure that you are connected to the secure version of a website. If an SSL-secured version of a website exists, it will seamlessly redirect you to it.

    Get a professional, secure email address.

    Last but not least, keep in mind that your email is a popular way for hackers to infect your devices with malware. Mailfence is an encrypted email suite that includes end-to-end encryption, digital signatures, and two-factor authentication (2FA). A calendar with polls and group management, an instant messaging service, and a document storage and management tool is  also included. All of these features are secure, which means your data is safe.
