"I will deploy the resources necessary to keep fans safe, and that decision will be mine," Beck said. "Public safety is my No. 1 goal."
There will be more police officers at the stadium, and according to Beck, there will be zero tolerance on misbehavior.
The Dodgers have agreed to pay for the boosted police presence.
Long-term strategies will look at technology, observation posts, license plate readers, parking lot lighting, environmental studies and increased community outreach.
Beck also announced that police officers will enforce a no-tailgating policy to ensure that fans are not drinking in the parking lot prior to the game.
The police chief also said officers would crack down on language used by fans at games.
"It's going to be a judgment call for officers," he said. "If people are making comments that inherently incite violence, then you have to go."
The security changes are in response to the beating of a San Francisco Giants fan by two suspects wearing Dodger gear on opening day. The suspects remain at large.
Bryan Stow, 42, remains in critical condition after the attack in the parking lot last week.
At the press conference, McCourt was peppered with questions about the reason for an uptick in fan safety complaints, which he skirted and instead focusing on his team's efforts to improve security.
He promised a safe, family-friendly, fan-friendly environment at Dodger Stadium beginning with the next game on April 14 against the Cardinals.
In response to people saying they don't feel comfortable at Dodger Stadium, McCourt said, "I hear loudly and I hear you clearly."
The Dodgers have also hired former LAPD Chief Bill Bratton to help review of security policies at the stadium and at the parking lot.
