It comes just days after similar legislation was scuppered at Westminster.
Holyrood To Get Security Upgrade
The Scottish Parliament is to spend almost £1.9 million on security upgrades in the wake of last year's attack on the Canadian parliament
A review of security at Holyrood was ordered after a lone gunman rampaged through the parliament building in Ottawa in October before being shot dead.
Security advisers have recommended additional measures be put in place in the Scottish Parliament's service yard area, including an upper storey extension to the gatehouse, new security kiosk and cycle turnstile.
The work is expected to be completed by May next year at a total cost of £1,873,000.
In a letter to MSPs, Presiding Officer Tricia Marwick said: ``The findings of the review recognised the robust security arrangements already in place on the parliamentary estate.
"The review also recommended additional measures to reflect the changing nature of the threat at home and abroad, in particular attacks by a lone individual or individuals.
"The SPCB (Scottish Parliament Corporate Body) has a legal duty of care to take all steps reasonably practicable to ensure the safety of all building users and the 300,000 members of the public who visit the Parliament each year.
"We believe the work proposed is prudent and proportionate in the current climate and is the right decision on behalf of those whose safety is our responsibility.
"The cost will be met from within the Parliament's existing resources by re-allocation of existing project expenditure and savings in other areas, so there will be no additional demand on the public purse.''
The officers were targeted as they responded to a call in the Knightswood area of Glasgow on Sunday night.
