6 essential tips to protect your data
It's time to take action. How about starting with small changes to ensure your digital security ?
1. Use strong and unique passwords
Your password is the gateway to your digital life. Don't leave it exposed. Create strong , complex passwords, combining uppercase and lowercase letters, numbers, and symbols. Passwords should be long and unpredictable, avoiding obvious sequences or easily accessible personal information.
No more using "123456" or your date of birth. Avoid using the same password across multiple accounts. Consider using a password manager to store and generate secure passwords. This helps ensure each account has a unique password without having to memorize them all.
Change your passwords regularly to minimize the risk of compromise. The ideal frequency may vary, but a good practice is to change them every few months. Notifications of suspicious login attempts should be treated as a priority, and passwords should be changed immediately.
2. Keep your software up to date
Updates aren't just about bringing new features. They ensure you have the latest security fixes. Outdated Software is an easy target for hackers, who exploit known vulnerabilities. Updates fix these flaws and improve overall system security.
Enable automatic updates. This ensures you don't miss important updates and reduces your risk of exposure to threats. Automating this process is a simple way to keep your systems protected.
Perform a "digital cleanup" every now and then. Review the software installed on your devices. Remove unnecessary or unused apps, as they can also pose a security risk. Less software means fewer entry points for potential attacks .
3. Use two-factor authentication (2FA)
This is your "two-factor lock." Two-factor authentication adds an extra layer of security by requiring two forms of verification before accessing an account. This could include a code sent to your phone or a fingerprint. Even if someone discovers your password, they won't be able to access your account without this second form of authentication.
Enable 2FA on all accounts that offer it. This is especially important for accounts that contain sensitive or financial information.
2FA significantly reduces the risk of unauthorized access, making your accounts much more secure. With this additional layer, hacking attempts become less likely to succeed. It's a simple yet powerful measure to protect your information .
4. Be aware of phishing
Phishing is a treacherous technique, a veritable "digital fishing." Be wary of suspicious emails or messages asking for personal or financial information Phishing emails may appear legitimate, but they often contain malicious links or attachments.
For businesses, solutions like Skyone's Phishing Test simulate real attacks to raise user awareness and reduce risk. These simulations help train employees to identify phishing attempts, reducing the chance of human error, which is the main gateway to attacks.
Always be suspicious. Verify authenticity before providing any information. Be wary of messages that create a sense of urgency or threaten consequences if you don't respond immediately. Contact the company or institution directly to confirm the legitimacy of the request.
5. Back up your data regularly
Have you ever thought about losing all your files, photos, and documents overnight? Regularly backing up your data ensures you have secure copies in the event of a cyberattack cloud storage solutions or physical storage devices to keep your data safe.
Establish a routine for your backups . Depending on the amount of data, you may need to perform daily, weekly, or monthly backups. Most importantly, periodically verify the integrity of your backups to ensure they can be restored when needed.
And last but not least: protect your backup ! Use encryption to protect your stored data. This adds an extra layer of security, ensuring that even if your backups are compromised, the data remains inaccessible.
6. Install reliable security software
Think of an antivirus and a firewall as the security guards for your digital home. security software can detect and neutralize threats before they cause damage. When choosing software , look for independent reviews and features like real-time protection and automatic updates.
For more robust protection, companies can rely on solutions like Skyone:
- Threat analysis : identifies vulnerabilities and guides prevention actions.
- WAF (Web Application Firewall) : Protects web applications from attacks and exploits.
- Network firewall : protects your network traffic from malicious and unauthorized access.
- SOC/SIEM : centralizes 24×7 security incident monitoring and response.
- EDR (Endpoint Detection and Response) : Monitors and responds to threats directly on devices.
Keep your security software up to date to ensure maximum effectiveness. Updates include new virus definitions and security improvements that are crucial for continued protection .
Combine your security software with safe browsing practices. Avoid suspicious websites and be cautious when downloading files from the internet. Remember that security software comprehensive security .
In a corporate environment , these security features cannot be treated as optional extras. When purchasing any technology or digital service, demand that features such as a firewall , real-time protection , threat analysis , and incident response be included as standard.
If the solution doesn't offer this level of protection, consider it a red flag . Information security isn't an extra; it's a prerequisite. This careful consideration should guide all of the company's technological decisions, as we'll see below.
Data protection in corporate environments
