Passwords should be Used
Studies have shown that at least seventy five percent of all people have shared a password with someone. While you know you will keep your password safe, there is no guarantee that the other person will. Do not give out passwords. Also, a network, by definition, is a connection of computers across distances. In this light, you can’t know whether someone on the network is being malicious. The only way to prevent malicious activity on a network is to be prepared for it. Use passwords that are alpha numeric. The longer the password, the better. Change your network password at least once every three months, and do not use names, birthdates, or obvious passwords like ‘password1.’
Use Firewalls and Encryptions
Data that is jumbled and mismatched will have no use to hackers; they like clear information that is easy to understand. With firewalls and encryptions, you not only ensure the data on a network is not accessible to unauthorized users, but it can ensure that if somehow they end up with it, it is jumbled and of no use to them. Most operating systems come with a firewall, but just in case, you may want to install one of your own. Encrypting data on a network is also useful if the information is to be shared via email. Ensure the network itself has passwords and security features on it. If these features are not visible, then the network might be unsafe.
Avoid Logging onto Remote Connections
Not every WIFI connection that is available should be used. Information technology professionals have said that most data is stolen over public networks. Computer criminals normally target these, as they give fewer problems to find and hack into. Users are encouraged to avoid using networks and network connections that are public. Public and unknown networks provide the perfect opportunity for data to be stolen or maliciously manipulated.
Hide IP Address
When the need arises to browse on a network without being detected, you might want to invest in a program that hides the IP address and allows users to browse anonymously. Though costly, these programs are reliable and consistent in terms of security. IP addresses for example that resemble 192.168.1.1 and 192.168.0.1 could be easily identified as being in the same geographical location. Hackers then can target network users by their geographical area. Hiding the IP can prevent this.
Back Up All Files
As simple as this sounds, it will come in handy when your computer crashes or you realize that you just cannot access the data. If encryptions were done as suggested earlier, there would be no need to worry, as you would have already had the information on a secondary storage device and it would be of no use to whoever is trying to access your data, as it is jumbled. Do not share information to users on a network, and try not to have a database on a network; that is a bad decision. Save the files on a secondary storage device.
