The Raspberry Pi is a credit score card sized computer that costs about $30 (£24).
Though the Pi had been connected to the community by the worker, lax controls over logging meant Nasa directors didn't realize it was present, said the report.
Raspberry Pi is a tiny device loaded with high-level capabilities.
The audit report recommended that Nasa do a better job of monitoring its network and tighten up its hack attack policies.
In 2011, hackers gained full access to JPL's servers and stole approximately 87GB of data, while a more recent hack in April 2018 saw attackers stealing around 500MB of data from one of NASA's major mission systems.
After NASA revealing the security incident, the Johnson Space Center in Houston disconnected its system from JPL's exploited gateway because of fears of hacking.
NASA's JPL's network is shared instead of being segmented, which is another aspect that helped hackers access numerous of the space agency's systems switch between different systems easily.
"JPL uses its Information Technology Security Database (ITSDB) to track and manage physical assets and applications on its network; however, we found the database inventory incomplete and inaccurate, placing at risk JPL's ability to effectively monitor, report, and respond to security incidents".
Following news of the data breach past year, the Johnson Space Center in Houston immediately disconnected from JPL and Deep Space Network's systems in order to protect NASA's other programs, such as those used by the International Space Station.
The malicious hacker won access to the Jet Propulsion Lab internal network via the Raspberry Pi by hijacking its user account.
As smartly as to having reduced visibility to devices linked to its network and to no longer retaining assorted substances of its network separate, investigators bear moreover discovered cases of security tickets no longer being resolved for extended lessons of time.
According to NASA, the security breach highlighted the weaknesses in its system. Yes, you read it right as NASA is giving you an opportunity to have your name shipped on a celestial body.
SpaceX Falcon Heavy Launch to Mark Several Firsts
The Air Force announced that it had selected the Falcon Heavy to launch its Air Force Space Command-52 (AFSPC-52) satellite. The mission will also involve four second-stage engine burns to take the satellites to their destinations.
