How can you minimise the risk of unauthorised access for your clients using firewall security testing?
A firewall is a vital first line of defence against a range of potentially crippling cyber-attacks, and whether they realise it or not, most people already have some form of firewall in place. This could be a built-in firewall in your laptop, computer or router, or a dedicated server firewall. However, how can you be sure that your firewall is really offering the protection you are expecting?
Why it’s important to test
Even if you have a firewall in place, it’s hard to gauge exactly what level of protection it is offering, and whether it’s really providing the shielding you need. In cyber-security, knowledge is power, and understanding the weaknesses of you, or your customers networks can empower you to take steps to increase your protection. This not only vastly decreases the risk of a cyber-attack, but also serves as a real value add for customers, showcasing how you are actively looking out for and improving their cyber-security.
How to test your customer’s firewall
There are a number of ways to test your customer’s firewall, from hit-and-miss online tools, to bespoke security services from leading cyber-security experts. Whichever route you take, there are a few things you should always look out for. Hackers use a variety of tools to highlight vulnerabilities in a network, one of the most common of which is open ports. Most systems, by default, will not actively open and close ports as required, but instead leave required ports open continuously, leaving them open to a hacker utilising a port scanning tool.
There are a range of accessible port scanning tools for you to try, and these can give you a basic understanding of which ports are currently being utilised, and whether or not you or your customers are vulnerable to specific ports, allowing you to go in and manage these accordingly to reduce risk.
Other important tests to carry out are the browser disclosure test, and a file sharing test. These are designed to highlight hidden access points and information sharing locations which could potentially be accessed remotely to gain entrance into a network, as well as allowing you to view the information which your browser is revealing about the system to those attempting to spot weaknesses.
