Android 4.1 or better known as Jelly Bean claimed to be more secure and harder from attacker (hacker) than any other Android version. Because this is the first version of Android that meets the Address Space Layout Randomisation (ASLR).
ASLR is a standard security against hackers who are looking for ways to install malware on the user’s device.
ASLR randomizing the memory locations for the library and other data structures, making it difficult for cyber criminals to smuggle malware (malicious programs) on the handset. This report is based on the results of the study a number of hackers and security firms on security arrangements in the Jelly Bean.
“As long as something is not random and ASLR does not work as long as the hacker knew it was there at the same location, they can use it to break into anything,” said Charlie Miller, a security researcher from research firm Accuvant. Miller pointed out, Jelly Bean is the safest Android OS because has full ASLR support.
