Firewall in Action: Protecting Trust-IT’s Network and Data
A firewall in Trust-IT refers to software used to protect a network or computer system from unwanted access or attacks. The primary purpose of the firewall at Trust-IT is to control the flow of data between the company’s internal network and the external world, based on predefined rules.
The three main types of firewalls are as follows:
- Packet Filtering Firewalls: These firewalls allow or block data packets based on IP addresses, protocols, and port numbers. They recognize packets based on their headers and information within them.
- Stateful Inspection Firewalls: These firewalls analyze data traffic in a sophisticated manner, taking into account the state of the communication. They create a state table to monitor traffic and decide whether to allow or block packets.
- Application Layer Firewalls: These firewalls operate at the application layer and detect which applications are being used during a connection. This allows them to make decisions based on the type of application and predefined rules.
Trust-IT uses firewalls for various purposes, including:
- Protection Against Malicious Attacks: Firewalls have the ability to block incoming attacks, such as DDoS attacks, network intrusion, and brute force password attempts.
- Access Control: Firewalls are used to restrict access to specific computers or services, providing an essential tool for maintaining the security of data and information.
- Data Traffic Control: By using firewalls, Trust-IT can control the type of traffic allowed to pass through their network, helping in effective bandwidth and resource management.
- Compliance with Security Policies: The use of firewalls is crucial for Trust-IT as it enforces security policies and ensures compliance with data security regulations and laws.
