If an organization has three information assets to evaluate for risk management purposes, as shown in the accompanying data, which vulnerability should be evaluated for additional controls first? Which vulnerability should be evaluated last? Switch L47 connects a network to the Internet. It has two vulnerabilities: (1) susceptibility to hardware failure, with a likelihood of 2, and (2) susceptibility to an SNMP buffer overflow attack, with a likelihood of 1. There is a 75 percent certainty of the assumptions and data. Server WcbSrv6 hosts a company Web site and performs e-commerce transactions. It has Web server software that is vulnerable to attack via invalid Unicode values. The likelihood of such an attack is estimated at 3. The server has been assigned an impact value of 5. There is an 80 percent certainty of the assumptions and data. Operators use the MGMT45 control console to monitor operations in the server room, it has no passwords and is susceptible to unlogged misuse by the operators. Estimates show the likelihood of misuse is 2. There are no controls in place on this asset, which has an impact rating of 4. There is a 90 percent certainty of the assumptions and data.

Program Plan Intro

Vulnerability:

  • Vulnerability refers to the exact methods that the threat agents can exploit for attacking an information asset.
  • It is also defined as a certain fault or a weakness found in an information asset, the security process, the design or even the management which can be exploited inadvertently.

Explanation of Solution

First evaluated vulnerability:

In this case, the second vulnerability will be estimated first.

Reason:

  • It is because of the reason that the vulnerability indicates that there is a kind of fault in the information asset control...

Explanation of Solution

Last evaluated vulnerability:

In this case, the third vulnerability will be evaluated last.

Reason:

  • It...
