LAN is a type of network that connects computers and devices in a specific and delimited area, such as an office or a building like our home. It is a very useful network when it comes to sharing data and information between the computers of an organization, a company or a house. Our home local network is where we spend most of the time when we connect to the Internet, for this reason it is essential to secure it correctly to prevent other users from having access to it and compromising our privacy that is why we must take steps to improve the Security in our LAN.
One of the most visible threats to security in LAN networks is a malware attack that could trigger the loss and theft of data and information relevant to the company. In addition to this, a virus has the potential to cause financial or reputational damage to a company.
Tips to improve LAN Security
But don’t worry, there are many ways to protect ourselves against these risks, which we will tell you about some very important ones.
▸Set up guest Wi-Fi
If a guest comes, it is essential to never give them access to the local network to ensure that they will not access our network. Typically all high-end routers incorporate Guest Wi-Fi functionality that prevents access to the local home network.
▸If possible get a data server
These servers help us to save all the relevant data of the installation and with its consequent well-defined copying process.
▸Get a good antivirus
Try to get an antivirus in all positions on the local network, even on the server, to be almost 100% protected against virus threats that exist on the network.
▸Password policy
Have an adequate password policy, each user of the local network with their personal password and also that it expires from time to time for greater protection.
▸Control of processes to detect possible problems
Have someone from the company or outsourced to control the copying processes to detect possible problems, update antivirus, centralize incidents of the local network and thus be able to notify technical service and control over the resolution of them
▸Encrypt the data
If the data we have on the NAS server is important and private, we can choose to encrypt the entire disk of the NAS or enable an encrypted folder. In this way, if they take the hard drive inside the NAS and try to read the information, they will not be able to since all the content is encrypted.
