A firewall engineer is usually in charge of ensuring the security of a computer network deploying and maintaining software. Firewalls are software programs that act as a defensive measure limiting which external sources are allowed to communicate with a network. They can be installed on a computer or built into devices as firmware. The use of such a program to keep a network protected from external threats is one of the main responsibilities of a firewall engineer. These engineers may also be tasked with teaching coworkers and others how to use computers safely and securely so that the network remains safe.
A firewall engineer’s work often entails the use of software to protect systems on a computer network from malicious threats. Firewall software is typically installed on computers and other networked devices, or it is available as firmware on a device. Firmware is a type of software that is installed as part of a piece of hardware rather than being kept separate like other types of software. Many employers expect a firewall engineer to weigh the pros and cons of various programs before selecting the security package that will best protect their company.
A firewall engineer may be required to create a new program or make significant changes to an existing one in some cases. This is frequently done if the network he or she is protecting has unique security concerns that must be addressed. Installing and maintaining a firewall is critical to a company’s security, as many external attacks can be avoided with the use of a good program. A firewall engineer is also responsible for responding to detected attacks, ensuring that the software is not compromised, and performing any necessary upgrades to keep a system safe.
The effectiveness of security software is frequently determined the actions taken its users. As a result, a firewall engineer must educate other people who use a computer network to ensure that they are not unwittingly posing security risks. This education can take up a lot of time because it ensures that other employees at a company are able to use their computers effectively and keep the network secure. Other users will have a better understanding of the network and will be able to resolve their own issues with the help of a firewall engineer, which will reduce the need for service requests.
