Security
See also: Browser securityChrome periodically retrieves updates of two blacklists (one for phishing and one for malware), and warns users when they attempt to visit a harmful site. This service is also made available for use by others via a free public API called "Google Safe Browsing API".
Chrome uses a complex process-allocation model to allocate different tabs to fit into different processes to prevent what happens in one tab from affecting what happens in others. Following the principle of least privilege, each process is stripped of its rights and can compute, but cannot interact with sensitive areas (e.g. OS memory, user files) — this is similar to the "Protected Mode" used by Internet Explorer 9 and 10. The Sandbox Team is said to have "taken this existing process boundary and made it into a jail." This enforces a computer security model whereby there are two levels of multilevel security (user and sandbox) and the sandbox can only respond to communication requests initiated by the user. On Linux sandboxing uses the seccomp mode.
In December 2011 a report by Accuvant, funded by Google, rated the sandbox security of Google Chrome 12 and 13 as better than either Internet Explorer 9 or Mozilla Firefox 5.

Famous quotes containing the word security:
“It is hard for those who have never known persecution,
And who have never known a Christian,
To believe these tales of Christian persecution.
It is hard for those who live near a Bank
To doubt the security of their money.”
—T.S. (Thomas Stearns)
“I feel a sincere wish indeed to see our government brought back to it’s republican principles, to see that kind of government firmly fixed, to which my whole life has been devoted. I hope we shall now see it so established, as that when I retire, it may be under full security that we are to continue free and happy.”
—Thomas Jefferson (1743–1826)
“There is something that Governments care for far more than human life, and that is the security of property, and so it is through property that we shall strike the enemy.... Be militant each in your own way.... I incite this meeting to rebellion.”
—Emmeline Pankhurst (1858–1928)
