Web security is an issue that affects us all. Every time you open a new page, you potentially expose yourself to risks that can compromise your personal information. But don't worry, there are ways to protect yourself and surf with confidence. In this article, I will show you how check the security of a website effectively and easily.
The HTTPS protocol: your first shield
When you visit a website, the first thing you should look at is the address bar. Do you see a closed padlock next to the URL? That's a good sign. It means the site uses HTTPS (Hypertext Transfer Protocol Secure), a protocol that encrypts the communication between your browser and the server.
If you don't see the padlock or it appears as "not secure," be careful. Especially if you're about to enter sensitive data like passwords or banking information. Not all is lost if a website doesn't have HTTPS, but it's definitely a order of flags that you should not ignore.
SSL Certificates: The Guarantee of Authenticity
The SSL (Secure Sockets Layer) certificate is like a website's ID. You can check it by clicking the lock icon and selecting "View Certificate." Here you'll find information about who owns the site and authority that issued the certificate.
A valid certificate ensures that you're on the site you think you are and not a malicious copy. Note the details:
- Check that the name of the site match the URL.
- Check the expiration date of the certificate.
- Look at who issued it. Authorities such as Let's Encrypt o DigiCert are trustworthy.
Privacy and Cookie Policies: Read the Fine Print
Yes, I know no one reads them, but you should take a look. A secure website will have a clear and accessible privacy policy. Find information about:
- How I know collect and use your data.
- With whom share your information.
- Your derechos as a user.
Cookie policies are also important. A responsible site will give you options about which cookies to accept and will explain to you what they are used for.
Security analysis tools
You don't need to be a cybersecurity expert to use some great tools. For example, VirusTotal (https://www.virustotal.com) allows you scan URLs for malwareSimply paste the site address and you'll get a detailed report.
Alternatively Sucuri SiteCheck (https://sitecheck.sucuri.net), which analyzes websites in search of malware, blacklists and other security issues.
Common sense: your best ally
All of these tools are useful, but nothing beats your intuition. If something seems too good to be true, it probably is. Pay attention to:
- Grammatical or spelling errors unprofessional design.
- Offers incredibly attractive without logical explanation.
- Information requests staff without apparent reason.
Keep your browser and antivirus updated
Your browser is your first line of defense. Update it regularly to get the latest security fixesThe same applies to your antivirus. These programs work hard to protect you, but they need to be up to date to be effective.
Secure Connections: Beware of Public Wi-Fi
Even if a site is secure, your connection might not be. On public Wi-Fi networks, hackers can intercept your traffic. If you must use one, consider a VPN (Virtual Private Network) to encrypt your connection.
Online shopping: check the payment gateway
If you are going to buy something, make sure that the payment page is secure. In addition to HTTPS, look for trust seals from companies like PayPal or recognized credit card services. Never enter bank details on a website you don't fully trust.
Social networks are a breeding ground for malicious links. Before clicking on a shortened link, use a URL expansion service to see where it'll actually take you. And if a friend sends you a suspicious link, ask them before opening it. Their account could have been compromised.
