What is a CDN and How Does It Improve Speed?

In today's digital world, every website owner wants his site to load fast and users to have a good experience. If a website is slow, visitors leave it quickly, which affects both traffic and business. The solution to this problem is CDN (Content Delivery Network) . But many people still do not understand what CDN is and how it increases the speed of our website. In this blog, we will learn step by step what CDN is, how it works and why it is important for modern websites. What is CDN? The full form of CDN is Content Delivery Network . It is a distributed network in which servers are spread across the world. These servers store copies of your website's content (such as images, videos, CSS files, JavaScript files, PDFs, etc.). When a user opens your site, the content is delivered to him from the nearest server. This makes the site load faster because the data does not travel from a far-off server. How does a CDN work? The working of a CDN is simple but the concept is powe...

How Can You Protect Your IoT Devices From Cyberattacks?

Securing your Internet of Things (IoT) devices is more important than ever, especially with the rise of smart homes and connected devices. These crucial actions will shield your Internet of Things devices from online attacks:

1. Modify the Preset Passwords

On your IoT devices, always change the default passwords. Make strong, one-of-a-kind passwords with a mix of characters, numbers, and symbols.


2. Consistently Update Firmware

Firmware updates are frequently released by manufacturers to address vulnerabilities. To keep your devices safe, make sure to install updates on a regular basis.

3. Turn Off Superfluous Features

In order to lessen the number of possible entry points for attackers, disable any features or services that you do not use, such as UPnP and remote access.

4. Employ a Different Network

For your IoT devices, create a different Wi-Fi network. By separating them from your primary network, this makes it more difficult for hackers to access your personal information.



5. Turn on two-factor verification (2FA)

Make sure all of your IoT devices have 2FA enabled. Because a second form of authentication is required, this provides an additional layer of security.

6. Keep an eye on network activity

Keep an eye on the traffic flowing through your network to spot any odd activity. To monitor connected devices, use network monitoring tools.


7. Turn Off Wasted Ports

To avoid unwanted access, close any ports on your router that are not in use. Hackers may find it simple to target open ports.

8. Keep Your Router Safe

By using WPA3 encryption, updating the firmware, and altering the default password, you can make sure your router is secure.

9. Use Third-Party Apps With Caution

On your IoT devices, stay away from installing third-party apps or software unless they are from reliable sources. Vulnerabilities may be introduced by malicious apps.



10. Educate Both You and Other People

Keep up with the most recent security threats and recommended procedures. Teach employees or family members how to use IoT devices safely.

You can keep your smart home or business secure and drastically lower the risk of cyberattacks on your IoT devices by adhering to these precautions.

A strong security feature that provides an additional degree of protection, two-factor authentication (2FA) makes it much more difficult for unauthorized users to access your accounts.  Two-factor authentication: what is it? Two forms of identification are needed to confirm your identity as part of the 2FA security process. This implies that a second factor is still required to access your account even if someone knows your password. You may have something, know something, or be something as this second aspect.  Typical 2FA Techniques 1. TOTP, or time-based one-time password: How it operates: Every 30 seconds, a unique code is generated via a time-based code generator software on your phone, such as Authy or Google Authenticator.  Benefits ...
