What is the most common security problem on a client/server network?
A.
Outdated software
B.
Old login accounts
C.
Non-secured ports
D.
Browser flaws
Explanation:
These are ALL common security problems, making the choice of the most common difficult. Non-secured ports has to be the most common because ports are open and non-secured by default. It takes an action to determine which ports should be enabled and which locked up, and then to actually secure them. For most of the nodes that are installed, there is usually no effort to lock down 1D0-470
the ports, especially for services not being used. Home users would be the most vulnerable because they will run a system right out of the box and not be aware of the ports being open and exposed. These systems are then connected to the Internet, without firewalls, and open the system for attack.
Incorrect Answers:
A: Outdated software could pose a threat if a known vulnerability was not corrected. Although this could be a common problem, it is not common security problem.
B: Old Login accounts don’t pose a major threat unless the accounts can be identified and breached.
D: Browser flaws are rare, but security loopholes are occasionally found.
