Anderson stopped 27 shots for his second shutout of the season, and Ottawa defeated the Pittsburgh Penguins 5-0 on Monday.
"We definitely had one of our better games this year and we played our most consistent game, playing hard-nosed and in their face," Anderson said.
"We know they have a good team and they bring it every night and they do things right 99 percent of the time so we found a way to win the game and do it with conviction."
Senators coach Paul MacLean was pleased with the timing of the victory.
"It's the best way we possibly could (head into the break)," MacLean said. "If we were looking for something under the tree that could be a motivator for us and a feel-good thing for us, beating Pittsburgh 5-0, we can head into this three-day break with a positive attitude."
Marc-Andre Fleury made 24 saves for the Penguins but had his five-game winning streak come to an end.
The win ended a three-game losing streak for the Senators with all three of those losses coming in Ottawa.
"I thought our response to the game tonight was workman-like and our penalty killers did yeomen work and the difference in the game was that we obviously killed off those power plays," MacLean said after his team survived all seven short-handed situations while scoring once in three power-play opportunities.
The Penguins had won 12 of their previous 13 games in Ottawa, including seven in a row. Pittsburgh had been shut out only once this season, as it fell 1-0 at home to the Colorado Avalanche on Oct. 21.
The shutout was the first for the Senators since they blanked the Buffalo Sabres 1-0 in their first game of the season.
Defenseman Marc Methot set an early tone that it was going to be a physical night.
With the Penguins breaking toward the Ottawa goal, Methot took Sidney Crosby out with a hard hip check. Crosby wasn't hurt on the play but his spinning body was catapulted into Pascal Dupuis, who went down and hit hard into the end boards.
Dupuis left the game with what was later described as a lower-body injury and did not return. Crosby was mostly ineffective the rest of the game.
"I haven't seen the replay. I don't know how low it was. He almost blew my knee out so it was pretty low," Crosby said.
"I don't know if it was right above my knee or above my hip, but it was awfully close."
"I have a ton of respect for that player," Methot said. "I think he's one of the best players in the world and you have to play him hard and that was our goal."
The two players had a lengthy discussion before play resumed while Dupuis was attended to behind the net.
"He wasn't happy about it, and I wouldn't be happy, either, so I don't blame him for coming at me a bit," Methot said. "I thought it was a clean hit. I've been throwing hip checks my whole career and I'm 6-foot-3 and I don't think I can get much lower than his knees."
Smith opened the scoring at 6:54 of the first period when he put a backhand in a very small opening between Fleury's left skate and the post after the Penguins goalie made a pad save on Cody Ceci.
In between those breakaways, Ryan scored his first goal in four games when he directed a point shot from Chris Phillips past Fleury at 5:46. It came on the same power play that the Senators surrendered Sutter's breakaway.
"A big part of the game was when they get the power-play goal to go up 2-0 and we have several chances on the power play," Penguins coach Dan Bylsma said.
"We had several good opportunities to score, but we don't cash in and certainly the game turns on that stretch where we had three power plays in the second and we don't get a goal."
The Penguins head into the break leading the Eastern Conference while the Senators are in 10th place, four points out of a playoff spot.
