Lancashire's police force is installing 3ami’s Monitoring and Audit System (MAS) to monitor staff use of computers.
The software will monitor all data input on the force’s network of terminals apart from passwords and confidential reporting.
The move comes as new regulations for data security are set to come into effect in March 2010.
The Association of Chief Police Officers’ (ACPO) Information Systems Community Security Policy requires all police forces in the UK to comply with a ‘protective monitoring’ regulation.
Lancashire Constabulary plans to use 3ami MAS to aid in investigations of any corruption-related issues involving staff use of computer systems. These issues include inappropriate disclosure of police information, interference with police evidence, breaches of information security and system infiltration.
Detective Superintendent Martyn Leveridge said: "It [the system] will provide us with the ability to resolve allegations of systems misuse more quickly and with more certainty."
As an overarching monitoring tool, 3ami MAS will bring together information from Lancashire Constabulary's existing auditing procedures and cover any systems not already being audited.
The software, which runs on Windows and uses a bespoke 3ami database system, will provide one central point for all reporting for auditing and monitoring purposes.
3ami did not disclose the specific length of the long-term contract with Lancashire Constabulary, but said it would be for more than one year.
Earlier this month, Greater Manchester Police was forced to shut down their network and cut links to the Police National Computer after the Conficker worm struck.
Investigators were leaning towards blaming the outbreak on an infected memory stick that someone plugged into a computer on the network.
