Businesses are increasingly reliant on inter-connectivity for file sharing and resource management. However, without proper security, these networks are prone to attacks. Cyber security firm bluecatnetworks.com lists some of the essential tips to remember when handling a network.
Encrypt your wireless points
Transferring sensitive data over an insecure network can cause that data to be intercepted by hackers easily. Use WPA2 encryption to lock down your WiFi and keep unauthorized access out.
Hide Your SSID
Your router comes with a name, or an SSID (service set identifier) that can be used to access the network. Making obvious which router is yours leaves it more prone to attack since. Instead, by hiding your signal, or my obscuring it to something generic, you can confuse attackers
Change Your Router’s Default Password
Manufacturers supply routers with a default password that is easily available online. A lot of malwares try to use brute force to guess this default password and gain access to your network. Change your password to protect your data.
Install Antivirus in PCs
Ensure that all devices on your network have antivirus installed. This way, no PC can get infected and, in turn, infect others. Viruses often take advantage of one unsecured device to spread across the entire network.
Put Your Web Server on a DMZ
By using a DMZ you can limit access to your internal network and can install much more security for the back-end while maintaining public access to the server. If your router doesn’t support a DMZ, get a new one.
Scan Regularly for Exploits
An important task is to shield against passive attacks like DNS spoofing by keeping a continuous check on your databases. Update passwords regularly, keep a track of the amount of data traffic and flag any suspicious activity. By remaining vigilant you nip any attack in the bud.
Limit Sharing of File Servers
A good way to lose your data is to broadcast your file servers on a public network. When accessing shared resources, you do not need to broadcast your entire hard disk. If you do, anyone can break in and gain control easily.
