SAN DIEGO (KGTV) -- San Diego security experts advise vigilance in the wake of the U.S. attack on Iran General Qassem Suleimani.Former Marine Pilot Ed Rush says Iran's options are limited when it comes to retaliation - but its two options appear to be a cyber attack or a terrorist attack. "We've protected ourselves pretty well at home here from terror," Rush said, noting he expects any attack to be abroad on a U.S. interest or embassy. San Diego Police say they have received no credible threat and have not increased patrols. RELATED: San Diego military bases tighten security amid rising tensions with IranStill, it's important to remain aware in San Diego, said aviation security expert Glen Winn. He noted San Diego is home to major military bases and is a magnet for tourism. Winn said visitors to attractions can expect more screeners when they go inside. "The most you can do is have people that are observing who is entering," Winn said. "Let's say somebody shows up in our kind of weather with a very heavy topcoat on or something like that - that's always an example used - why are you wearing a topcoat coming into the safari park and it's 75 degrees outside?" Winn also noted a wide range of agencies run frequent drills to prepare for any attack.

But he noted the U.S. is fending off cyber attacks almost constantly. "This is going on all the time," he said. "There are always other governments attempting to access infrastructure in the U.S."Linlor says the attacks are likely to target large scale systems, and not individuals. 1825
