What is a web firewall and why do London businesses need it?A web firewall is a security device that sits between your website and the internet, acting as a gatekeeper to filter out unwanted traffic and prevent cyber threats. It examines every incoming and outgoing network packet to determine whether it’s legitimate or malicious. If the packet is deemed safe, it’s allowed to pass through the firewall and reach its destination. If it’s flagged as a threat, it’s blocked from entering the network, and an alert is sent to the administrator. London businesses need web firewall services to protect themselves from cyber threats. According to a report by the UK government, 46% of businesses in the country experienced a cybersecurity breach or attack in the last 12 months. The report also states that the average cost of a cyber attack for a small business is £1,300, rising to £3,100 for a medium-sized business and £22,700 for a large business. With the cost of cybercrime rising every year, it’s more important than ever for businesses to invest in web firewall services to protect their online assets. Web firewalls come in different types, each with its strengths and weaknesses. Understanding the different types of web firewall services can help you choose the right one for your business.
Types of web firewall services
- Packet filtering firewalls: Packet filtering firewalls are the most basic form of firewall. They examine each packet of data that passes through the network and compare it against a set of predefined rules. If the packet matches the rule, it’s allowed to pass through the firewall. If it doesn’t match the rule, it’s blocked. Packet filtering firewalls are simple to set up and are effective in blocking known threats. However, they’re not very good at detecting and blocking new threats that don’t match the existing rules.
- Stateful inspection firewalls: Stateful inspection firewalls are similar to packet filtering firewalls, but they keep track of the state of each network connection. They examine each packet of data that passes through the network and compare it against a set of predefined rules. If the packet matches the rule, it’s allowed to pass through the firewall. If it doesn’t match the rule, it’s blocked. Stateful inspection firewalls are more effective than packet filtering firewalls in detecting and blocking new threats.
- Application-level gateways: Application-level gateways are also known as proxy firewalls. They examine each packet of data that passes through the network and compare it against a set of predefined rules. If the packet matches the rule, it’s allowed to pass through the firewall. If it doesn’t match the rule, it’s blocked. Application-level gateways are more effective than stateful inspection firewalls in detecting and blocking new threats. They can also perform deep packet inspection to examine the content of each packet.
- Next-generation firewalls: Next-generation firewalls are the most advanced form of firewall. They combine the features of packet-filtering firewalls, stateful inspection firewalls, and application-level gateways. They also incorporate additional security features, such as intrusion prevention systems (IPS), antivirus, and anti-malware. Next-generation firewalls are the most effective form of firewall in detecting and blocking new threats.
