Cybersecurity 101. Tips for newbies

In an increasingly connected world, cybersecurity has become a constant concern for most people. More and more, we store important data online, from banking information to personal photographs. However, the security of this data is often overlooked, leaving users vulnerable to cyber attacks. In this post, we'll give you some practical tips for protecting your data and your privacy online.

What is cybersecurity?

Cybersecurity refers to the protection of devices, networks and information systems against unauthorized access or malicious use of data.

Why is cybersecurity important?

Cybersecurity is important because in an increasingly connected world, cyber attacks are becoming more common. Hackers can gain access to personal, financial and confidential information, which can result in identity theft, financial fraud and other serious consequences. Cybersecurity helps protect users and businesses from these attacks.

Tips to improve your cybersecurity

1. Use strong passwords

It is surprising how many people use weak and easy-to-guess passwords. While the general recommendation is to have unique and complex passwords for each of your online accounts, our advice is to focus on your email password. With it, you are able to change your credentials for any other account (with a recovery email).

Use a combination of letters, numbers and symbols and avoid using personal information such as your date of birth or your pet's name. It is also highly recommended that you update your passwords from time to time (6-12 months).

If you have trouble remembering your passwords, we recommend that you use a "passphrase". They are more secure and easier to remember.

If you want to find out how secure your password is, you can use passwordmonster to test until you find the right one. Here is an example:

Another great option is to use a password manager. If you use the same browser on all your devices, you can use the default tool in Chrome, Firefox or Safari.If you prefer to use an external application and are looking for a free option, we recommend bitwarden.

2. Keep your devices updated

Software updates often include security patches to protect your device against known vulnerabilities. Be sure to keep your devices updated with the latest software version. Also, if you are using older devices, consider upgrading to newer devices that are designed with the latest security technology.

If you want to throw away an old device, be sure to format it. Several times, or better yet, using an external application. Even after the data is erased, it can still be recovered by someone with the right knowledge or tools. We recommend this guide if you want to get rid of an old phone.

3. Learn how to identify phishing emails

Phishing emails are one of the most common forms of cyber attacks. Attackers often pose as a legitimate company or service in an attempt to steal personal information from you. If, after clicking on the email, you are asked for a username and password... be wary.

Learn to identify these emails by looking closely at the sender of the email, especially the email domain (what follows the @). Don't forget to look carefully at the url, if you finally decide to click on a suspicious link.

4. Use Two-Factor Authentication

Two-factor authentication (2FA) is an additional layer of security that requires users to provide a second form of identification before accessing an online account. Most online services offer 2FA, such as a physical security key or a code sent to your mobile phone. Be sure to activate 2FA for all your online accounts.

How can I know if my company is protected against cyber attacks?

It is important for businesses to take steps to protect themselves against cyber attacks. Some things you can do to make sure your business is protected include:

• Hire a cybersecurity expert to perform a risk assessment and make recommendations to improve the company's security.

• Implement Information security policies and ensure that all employees are trained to follow these policies.

• Use security software and keep it updated to protect the company's network and devices (Windows deffender works great if you have it enabled).

• Perform regular penetration tests to identify vulnerabilities and fix them before they can be exploited by hackers.

• Keep the server software and the software you develop updated and secure, as well as the libraries you use.

• Use the recommendations from OWAS to test your cybersecurity. Their software is free and open source, if you want to go to the next level.

• Use a WAF (Web Application Firewall) such as Cloudflare, especially if you are a company.
