Firewall

The glossary of statistical terms, published by the Organisation for Economic Co-operation and Development (OECD), defines a firewall as: ‘A hardware- and/or software-based system that is used as an interface between the internet and a computer system to monitor and filter incoming and outgoing communications.’

Guide to Controls (BG 83/2023) written by John Marrow and published by BSRIA in June 2023, defines a firewall as: ‘…usually a piece of software but can also be hardware. Based on a set of security parameters, it exists on a network to check and prevent data entering the system from external sources such as the internet. The presence of a firewall on a corporate network can also block the passage of data between interconnected networks, also known as an intranet. Hence if the BMS network forms part of the client network this can help prevent malware or hackers penetrating the client site.’
