Texts: Sally Parr is a social media editor for Bravo Manufacturing, a company which builds ruggedized computer systems for the aerospace and defense industries. Among Sally's duties is monitoring a discussion forum which the company hosts on one of the web servers in its DMZ. Bill Fernley is a web developer and administrator who maintains the company's Internet-facing systems - web server, mail gateway, etc. He works closely with Mike Chambers, a security analyst reporting to the CISO. On Monday morning, Sally is reviewing the weekend's posts on the discussion forum to make sure that any customer questions get answered. When she opens one discussion thread, a browser dialog window pops up, reading "Test - please ignore". She calls Bill to ask whether he is doing any testing, but he says, "No - the system hasn't been patched or updated for over a month". Bill executes an SQL query on the database which backs the discussion forum, in order to get the text of the last week's posts: SELECT post_text FROM forum_posts WHERE post_date BETWEEN '2019-01-18' AND '2019-01-25'; He immediately spots an entry from the previous evening with text that reads: '<script>alert("Test - please ignore");</script>'. Bill reports what he has found to Mike, who must quickly install some kind of compensating control. Which control would be most appropriate? Select one: 1) A packet-filtering firewall 2) A spam filter 3) A web application firewall. Which phase of the cyber intrusion kill chain has the attack reached, according to this evidence? Select one: 1) Weaponize 2) Reconnaissance 3) Deliver.
