DRM CORRECT ANSWER Answer: A, B Explanation: You can use either a certificate revocation list (CRL) or Online Certificate Status Protocol (OCSP) to check for certificate revocation, depending on which type of PKI is deployed. Your company has an intrusion detection system (IDS) and firewall deployed on the perimeter of the network to detect attacks against internal resources. Yesterday, the IDS alerted you that SSL sessions are under attack, using an older exploit against SSLv2. Your organization's web server must use encryption for all financial transactions. You need to prevent such an attack from being successful in the future. What should you do? A. Block SSLv2 on the firewall. B. Block SSLv2 on the web server. C. Disable SSLv2 and enable SSLv3 on the web server. D. Update the web server with the latest patches and updates.

Your company has recently decided to merge with another company. Each company has its own Internet PKI that deploys certificates to users within that network. You have been asked to deploy a solution that allows each company to trust the other's certificates. What should you do? A. Issue a policy certificate accepting both trust paths. B. Deploy a new PKI for all users and import the current user certificates to the new PKI. C. Use a cross-certification certificate. D.

Your company has a single, centralized web-based retail sales system. Orders come in 12 hours per day, 364 days per year. Sales average $500,000 per day. Attacks against the retail sales system occur on a daily basis. For the retail sales system, there is a 1% chance of a hacker bringing the system down. The mean time to restore the system is 6 hours. What is the ALE for this system? A. $912,500 B. $250,000 C. $500,000 D. $910,000 CORRECT ANSWER Answer: D Explanation: The annualized loss expectancy (ALE) for the system is $910,000. The asset value (AV) is $500,000. The exposure factor (EF) is 0.5 (6 hours/12 hours). Single loss expectancy (SLE) = AV × EF = $500,000 × 0.5 = $250,000 Annualized rate of occurrence (ARO) = 0.01 × 364 = 3.64 Annualized loss expectancy (ALE) = SLE × ARO = $250,000 × 3.64 = $910,000 Your organization has recently implemented several new security policies in response to a recent risk analysis. One of the new policies states that controls must be configured to protect files from unauthorized or accidental deletion. Which aspect of security does this new policy address? A. confidentiality B. integrity C. availability D. authorization CORRECT ANSWER Answer: B Explanation: Configuring controls that will protect files from unauthorized or accidental deletion addresses data integrity.

Your company completes a risk analysis. After the analysis, management requests that you deploy security controls that will mitigate any of the identified risks. Management indicates that there is an expected level of residual risk that they expect. What is residual risk? A. risk that is left over after safeguards have been implemented
