A. Physically securing access points such as wireless routers, as well as preventing
theft, addresses the risk of malicious parties tampering with device settings. If
access points can be physically reached, it is often a simple matter to restore weak
default passwords and encryption keys, or to totally remove authentication and
encryption from the network.
B. Service set identifiers (SSIDs) should not be used to identify the organization
because hackers can associate the wireless local area network (WLAN) with a
known organization and this increases both their motivation to attack and,
potentially, the information available to do so.
C. The original Wired Equivalent Privacy (WEP) security mechanism has been
demonstrated to have a number of exploitable weaknesses. The more recently
developed Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access 2 (WPA2)
standards represent considerably more secure means of authentication and
encryption.
D. Installing Simple Network Management Protocol (SNMP) on wireless access
points can actually open up security vulnerabilities. If SNMP is required at all, then
SNMP v3, which has stronger authentication mechanisms than earlier versions,
should be deployed.

A consulting firm has created a File Transfer Protocol (FTP) site for the purpose of
receiving financial data and has communicated the site's address, user ID and
password to the financial services company in separate email messages. The
company is to transmit its data to the FTP site after manually encrypting the data.
The IS auditor's GREATEST concern with this process is that:
Select an answer:
A.
the users may not remember to manually encrypt the data before transmission.
B.
the site credentials were sent to the financial services company via email.
C.
personnel at the consulting firm may obtain access to sensitive data.
D.
the use of a shared user ID to the FTP site does not allow for user accountability.

A. If the data is not encrypted, an unauthorized external party may download
sensitive company data.
B. Even though the possibility exists that the logon information was captured from
the emails, data should be encrypted, so the theft of the data would not allow the
attacker to read it.
C. Some of the employees at the consulting firm will have access to the sensitive
data and the consulting firm must have procedures in place to protect the data.
D. Tracing accountability is of minimal concern compared to the compromise of
sensitive data.
During an IS risk assessment of a healthcare organization regarding protected
