Block 4 Unit 1 Part 5 Review

Why might a network have substandard security?

• The administrator doesn't have any experience and is trying to mimic his home network.

• The security guards are asleep

• The network interface card is bad

• The router is not configured with 802.1X security

Why would a network be hacked?

• Because the network contains information in the form of data that is valuable to the attacker

• Because Summers really likes hacking the government

• Because networks have a giant "Hack me" .txt file written on them.

• Because of some reason

What is a common vulnerability with Wireless networks that results from extended broadcast ranges?

• No physical boundaries

• Overlooking physical security

• Man-in-the-middle attacks

• Leaving end-user devices vulnerable

What is overlooking physical security?

• Not employing physical security such as guards or mantraps.

• Not allowing an attacker in because he is an unwelcome guest

• Putting a router in your network where it doesn't belong

• Not adding security measures such as encryption in a network

What is Leaving end-user devices vulnerable?

• Watching Clarke in his natural habitat, studying.

• Allowing virus's to have a pathway into your network through end user devices

• Meyers is watching

• Connecting users through remote connections to the desktop

What occurs during a Man-in-the-middle attack?

• An attacker is able to intercept and view then forward data packets

• An attacker is able to destroy files from inside the company

• An attacker gains access to the network through the TCP port 3389 RDP

• Nothing happens

What are the five distinct classes of network attacks?

• Passive

• Active

• Close-in

• Insider

• Distribution

What are passive attacks?

• Traffic analysis of unprotected or weakly encrypted traffic.

• A third party service enabling an attack to happen through reduced security measures

• An attempt to break into the network

• An insider passively takes information from the company and distributes it to attackers

What is an active attack?

• An attempt to break into a protected network or break protection measures.

• Includes traffic analysis

• Attacker sits in broadcast range to pick up wireless transmissions

• Malicious modification of hardware at a factory before distribution.

What is a close-in type of attack

• An attacker sits in the range of a wireless network to gain access or information through data emissions

• An attempt to break into a network

• An attempt to break a security measure

• Traffic analysis
