A firewall is a tool that monitors the traffic entering or leaving a network and aims to block any users that appear suspicious. Firewalls can be hardware or software based and have different features depending on their type. For example, a firewall in simple form will filter web traffic based on its source, whereas a more advanced option will have extra levels of protection and control. As well as being installed at the edge of a network, firewalls can be used internally to break it down into smaller subnetworks. This has the benefit of denying hackers access to the whole network if the security of one part is compromised and comes under threat.
Virtual private network (VPN)
A VPN enables an employee to work outside their office and access corporate networks securely. It does this by protecting their identity and masking their location, regardless of whether they’re logging on at home, or using a public Wi-Fi connection. This encrypted connection prevents hackers from gaining unauthorised access and ensures that any sensitive data is transmitted safely. Because smartphones and tablets can also benefit from communicating through a VPN, this method is a useful security tool for corporations who have employees who work remotely and require additional network security.
