Difference between “dateline” and “deadline”
Honestly, I never get it right when it comes to using these words. Most of the time I used dateline, and now I know it was wrong. But I believe most of us did not realize it either.
What is the difference between dateline and deadline?
Dateline is the day and time something happened, most often a news report, for example “Dateline Friday, June 26, 2015 at 10:00 a.m., the U.S. Supreme Court has announced that same-sex marriage is required by the Constitution.”
KRACK – Wifi is no longer secure
Weeks ago a well known attack discovered on WPA2, a protocol that secures protected wifi networks. The vulnerability is related a key reinstallation attack, or known as KRACK.
It attacks the design or implementations flaws in the WPA2 protocol of Wi-Fi standard, or what is known as the four-way handshake (network authentication protocol) to reinstall an already-in-use key, which then resets the key and allows the encryption protocol to be attacked. To guarantee security, a key should only be installed and used once. But the research paper found this is not guaranteed by the WPA2 protocol which leads to the high possibility of this weakness to be abused.
