"I have instructed the military to increase its intelligence preparations and prepare what is needed so that ... (if necessary) ... we will be able to consider carrying out an operation," Barak said in an interview on Channel 10 television.
"We are following ... the possible transfer of advanced munitions systems, mainly anti-aircraft missiles or heavy ground-to-ground missiles, but there could also be a possibility of the transfer of chemical means (weapons) from Syria to Lebanon," he added.
"The moment (Syrian President Bashar al-Assad) starts to fall we will conduct intelligence monitoring and will liaise with other agencies," Barak said.
Hezbollah, which has in the past received military and financial support from Syria and Iran, launched thousands of mainly short-range rockets into Israel during Israel's 2006 offensive in southern Lebanon, but some longer-range rockets reached central Israel.
Their border has largely remained quiet since then.
On Thursday, Barak toured the Golan Heights, a strategic plateau that Israel captured from Syria in the Middle East war in 1967 and from where it can monitor movements inside the territory of its northern foe.
Barak said Israeli troops were preparing to prevent an influx of refugees into territory that Israel controls there.
"They (refugees) have not chosen to come close to us, but in the event of the regime's downfall, which could happen..., (Israeli forces) here are alert and ready, and if we have to stop waves of refugees, we will stop them," Barak said.
Syrian rebels have assassinated four of Assad's closest aides in Damascus and seized three border crossings with Iraq and Turkey this week, putting the Syrian leader under greater pressure than at any time in the 16-month uprising against his rule.

Ehud Barak is out of his mind. He would be adding more fuel to the fire, should Israel launch an attack on Syria, just to secure Assad's arsenal of chemical weapons. It would make Assad's day and he could play the victim of Western and "zionistic" aggression and might win sympathy allies and foes in the region.
