Network security is essential for keeping your data and IT systems as secure as possible. Almost all businesses are connected to the internet and almost all devices have internet access to allow users to perform day to day to tasks.
Firewalls are necessary for any business that has devices connected to the internet. They act as a gateway to and from the internet and are the first barrier between the outside world and your business.
You should check you have a sufficiently secure firewall in place to stop malicious communications from entering your business network. Firewalls block network traffic by looking at the address and protocol information contained within the data that is being sent. By correctly configuring your firewall, you can accept and deny such data based upon ‘rules’. These rules specify what is and is not allowed in to your network. If the rule is met, the connection and data are accepted, if it fails they are denied and the traffic is refused entry.
It is also important to check that your firewall has had its default username and password changed, we still see devices with default passwords in place. If you can, set your firewalls to only accept connections from trusted internet addresses. This can reduce the vulnerability of the device and the possibility of someone gaining control over it.
Most businesses are likely to have a wireless network implemented in their environment. However, how does this affect your network security?
As wireless networks transmit data over the air, anyone with a wirelessly enabled device could be snooping on your data. You must ensure anyone who can see your wireless network is not able to intercept or read the information being sent. Should someone be able to intercept your data and information you cannot guarantee the security and integrity of the data and it’s an easy entry point for hackers.
How can we secure your wireless network?
Encryption should always be configured on wireless networks. This can help you ensure the data flowing over the wireless network is secure. The WPA2 encryption standard should be implemented for your wireless network; this is the current recommended standard for wireless encryption.
You should change the keys regularly, your wireless keys are no different to your passwords. When staff members leave you should change them and only allow authorised people access to these keys. Alternatively, you can tie your wireless network to a source of user authentication within your business such as Active Directory. This can help identify malicious use and means when the users account is disabled their access to the wireless network is automatically removed at the same time.
Guest networks should be created to separate your internal corporate network from any network that allows guest access. As with your own network, wireless keys should also be changed with frequent regularity for obvious reasons.
