Prime Minister Manmohan Singh, who will chair the meeting, is expected to hold threadbare discussions with the CMs on the country's security situation and measures to be adopted to maintain law and order.
A separate meeting of Chief Ministers of seven Naxal affected states will also be held later in the day to specifically discuss the situation arising out of Maoists violence.
The conference will review the information collection system -- both technical and human intelligence -- its proper sharing and necessary action, modernisation of police forces, procurement of arms and ammunitions, filling up of vacancies besides providing training to security forces.
"Naxal menace is primarily indigenous and home grown. Terrorism, on the other hand, is largely sponsored from outside the country, mainly Pakistan, which has utilised terrorism as an instrument of State policy. The meeting will take note of all these issues," a Home Ministry official said.
The recent pattern of terrorist incidents also suggested that increasingly the attacks have a pan-Indian and trans-national aspect and the terrorists have been able to employ new skills, including modern communications skills.
Use of Internet and Voice Over Internet Protocol connectivity gives terrorists greater anonymity and makes detection difficult for the authorities.
"The meeting is expected to focus on the technological upgradation of all police forces and on how the Central government can help the states," the official said.
In the last conference of the Chief Ministers on January 6, the Prime Minister had accused Pakistan of utilising terrorism as an instrument of state policy and said given the "sophistication and military precision" of the Mumbai terror attacks, they must have had the support of some official agencies in that country.
He had said those in-charge of terrorist infrastructure in Pakistan have resorted to other stratagems to push in terrorists into India via Nepal and Bangladesh though infiltration has not totally ceased via the Line of Control also.
