Apple seems to have woken up to the need to tighten its security after it lost an iPhone prototype for the second time — this time it's about the upcoming iPhone 5.

Two job listings appeared at the company website looking for managers to bump up its “new product security” program that includes staff who used to work for the FBI and other law enforcement agencies.

The individual will collaborate with other security managers by contributing to, and managing execution of, strategic initiatives set forth by Director, Global Security, read the job posting.

Otherwise, Apple has not given much information about its security operations, maintaining its reputation for secrecy.

Apple had not commented about the lost iPhone 5 prototype so far. San Francisco police reportedly said that four officers along with two Apple employees went to a home in the city’s Bernal Heights neighborhood, where they met the suspect and searched for the lost iPhone prototype.

Losing a prototype may affect the company's marketing plans, more so if the product involved is the iPhone 5. The new managers have to do damage control now not merely about the exposure of the details but also about the possible infringements of the company patents and the intellectual properties.

Security experts also hint at serious threats coming from the growing Chinese smartphone and tablet market, where thousands of workers are outsourced with the actual manufacturing of the product.

Several fake Apple stores have been tracked in China recently where iPods and iPhones are sold at lower prices.

Apple’s move to maintain security is crucial as many companies are set to topple it from its position and expose its plans and details.

Several media reports suggest that the most-anticipated iPhone 5 will arrive sometime in October.
