HTTPS: The Lock That Protects Your Customers' Data

HTTPS is the encrypted version of the web protocol: everything a visitor sends to your site (their name, phone number, message) becomes unreadable to anyone intercepting the connection. Modern browsers show a 'not secure' warning on sites without it, and that warning alone is enough to drive a customer away.

Since 2014, Google has used HTTPS as a signal in its ranking and officially recommends adopting it, for users' safety as much as the site’s own. The certificate does not have to cost you anything: Let’s Encrypt, a non-profit authority, issues it free and automatically, and most Algerian hosts offer one-click activation from the control panel.

  • Ask your host to activate and renew the certificate automatically.
  • Redirect all old HTTP addresses to the HTTPS version (301 redirect).
  • Check that the padlock appears without warnings on every page.

Updates and Backups: Your Recovery Plan

Most successful hacks exploit known flaws in content management systems and their plugins, not sophisticated attacks. Google recommends keeping a list of every installed piece of software and plugin with its version number, and applying each security patch as soon as it is published. A site left unpatched for months is an open door.

Backups are the net that catches you when you fall: a weekly copy of the files and the database, stored away from the site’s server, with a regular restoration test. A simple rule: three copies, on two different media, one kept off-site.

  • Update the CMS and plugins within days of a security patch release.
  • Remove unused plugins and themes.
  • Schedule a weekly automatic backup and test the restoration every two months.

Strong and Unique Passwords for Every Account

Attackers do not just guess passwords: they replay lists of passwords stolen from other sites against many websites. The first rule is uniqueness: a different password per account, long and not from the dictionary. For storage, OWASP sums up the requirement in one sentence: never store a password in plain text, always a slow hash such as Argon2id or bcrypt, with a unique salt.

Since nobody remembers dozens of long passwords, use a password manager that generates and stores them, and enable two-factor authentication on the admin account and on the email tied to it: email is the recovery key for every other account.

  • One password per account, at least 12 characters long.
  • Enable two-factor authentication on the admin panel, email and hosting.
  • Never send a password by email or chat.

Security Headers in Plain Language

A security header is a short instruction the server sends with every page; the browser reads it and adjusts its behaviour. The OWASP Secure Headers Project documents the main ones, which are configured once by the site’s developer:

The owner does not need to understand the technical details: ask the developer to enable them and have them checked once a year. It is a free layer that automatically blocks certain types of attacks.

  • HSTS: forces the browser to always use the encrypted connection with your site.
  • X-Frame-Options: prevents your site from being displayed inside another page to trick visitors.
  • X-Content-Type-Options: stops the browser from guessing file types in a way that could run malicious code.
  • Content-Security-Policy: a whitelist of sources allowed to load in your pages.
  • Referrer-Policy: limits what your pages reveal about the visitor’s previous page.

Your Site Is Hacked: The First Hour

Time is decisive. The order below follows Google’s guidance for compromised sites:

If your site collects customer data and it was affected, remember that Algerian Law 18-07 requires the data controller to put in place appropriate technical and organizational measures for the confidentiality and security of processing (articles 38 and 39): an incident affecting your customers' data is more than a technical problem.

  • Take the site offline or isolate it: a maintenance page or a locked admin panel, rather than letting your pages serve fraudulent content.
  • Change every password: admin panel, hosting, database, email, from a clean device.
  • Assess the damage: check the Security Issues report in Google Search Console and look for unknown pages created by the attacker (type site:your-domain-name in Google).
  • Restore a clean backup from before the hack, after checking it for malware.
  • Update everything, then request a review from Google if a warning is displayed.

A Practical Security Checklist

Print this list and review it every quarter, or make it a standing item in your meetings:

  • HTTPS active, auto-renewed, no browser warnings.
  • CMS and plugins up to date, unused components removed.
  • Weekly automatic backup, successful restoration test this month.
  • Unique passwords on every account, two-factor authentication on.
  • Security headers enabled and verified.
  • Google Search Console account active, security alerts followed.
  • A named person owns security and keeps a document describing these settings.
