How to Protect Yourself on a Public Network?

Differences between public and private network
Consider the network as a gateway to the Internet. Often, if this access is free, we speak of a public network. This is the case of networks found in libraries, shopping malls, restaurants, etc. If, on the contrary, we need a key, or a password, then we speak of a private network.
The IT security issues on a public and private network are similar:
On a public network:
- Your data is not protected;
- Anyone can connect without authenticating;
- The network generally bears the same name as the place where it is offered (for example, “WiFi mall”).
On a private network:
- Your data is not always protected;
- Everyone can connect with authentication;
- You need a password, or a security key, to connect to it.
The main dangers of public and private networks
Did you know that since teleworking has become popular, the number of hacking attempts has exploded? To secure your data, inform your employees of the points that require their attention during a public and private connection:
- Data confidentiality: public networks do not encrypt your data optimally. A hacker can easily manage to find the key that will allow him to access your information.
- Malware and viruses: if a public network is infiltrated by hackers, hackers can force the installation of malware on users’ devices. This allows them to spy on your activity and access your sensitive information continuously.
- Network spoofing: double-check the name of the public network you are connecting to. It is possible for a hacker to create a fake public network, whose name is modelled on the original. By connecting to the wrong WiFi, you provide prime access to cyber threats.
Some companies have a public network in addition to their private network. We think for example of the guest network, which gives WiFi access to visitors without interfering with the network of employees.
- Give it a distinct name: reserve its use strictly for visitors. Its title must not lead to confusion with your main network;
- Assign it a different password to be regularly renewed;
- Limit its distribution, so that it is not visible outside your offices;
- Make sure your firewalls, antivirus and router are up to date.
This is an essential aspect, which should not be neglected.
Prevention of malicious intrusions, protection against data theft; strengthening the computer security of your networks, it is your reputation and your identity that you are protecting.
