/var/log/mailog ?le generally contains the source and destination IP addresses, date and time stamps, and other information that may be used to check the information contained within an e-mail header. Linux uses Syslog to maintain logs of what has occurred on the system. The configuration file /etc/syslog.conf is used to determine where the Syslog service (Syslogd) sends its logs. Sendmail can create event messages and is usually configured to record the basic information such as the source and destination addresses, the sender and recipient addresses, and the message ID of e-mail. The syslog.conf will display the location of the log file for e-mail. Answer: B, C, D are incorrect. All these files are not valid log files.

An anomaly based Intrusion Detection System will monitor the network for any activity that is outside normal parameters (i.e. an anomaly) and inform you of it. Answer: C is incorrect. Antivirus software, while important, won't help detect the activities of intruders. Answer: B is incorrect. Performance monitors are used to measure normal network activity and look for problems such as bottlenecks. Answer: A is incorrect. A protocol analyzer does detect if a given protocol is moving over a particular network segment.

The Internal Audit Association lists the following as key components of a database audit: Create an inventory of all database systems and use classifications. This should include production and test data. Keep it up-to-date. Classify data risk within the database systems. Monitoring should be prioritized for high, medium, and low risk data. Implement an access request process that requires database owners to authorize the "roles" granted to database accounts (roles as in Role Based Access and not the native database roles). Analyze access authority. Users with higher degrees of access permission should be under higher scrutiny, and any account for which access has been suspended should be monitored to ensure access is denieA, Dttempts are identified. Assess application coverage. Determine what applications have built-in controls, and prioritize database auditing accordingly. All privileged user access must have audit priority. Legacy and custom applications are the next highest priority to consider, followed by the packaged applications. Ensure technical safeguards. Make sure access controls are set properly. Audit the activities. Monitor data changes and modifications to the database structure, permission and user changes, and data viewing activities. Consider using network-based database activity monitoring appliances instead of native database audit trails. Archive, analyze, review, and report audit information. Reports to auditors and IT managers must communicate relevant audit information, which can be analyzed and reviewed to determine if corrective action is required. Organizations that must retain audit data for long-term use should archive this information with the ability to retrieve relevant data when needed. The first five steps listed are to be performed by the auditor manually. Answer: B, D are incorrect. These tasks are best achieved by using an automated solution.

In such a scenario, John will use Hunt which is capable of performing both the hacking techniques, sniffing and session hijacking. Answer: D is incorrect. Ethercap is a network sniffer and packet generator. It may be an option, but John wants to do session hijacking as well. Hence, he will not use Ethercap. Answer: A is incorrect. IPChains is a firewall. Answer: B is incorrect. Tripwire is a file and directory integrity checker.

Ryan can either choose WEP or WPA-PSK wireless protocol to set an ad hoc wireless network.

Answer: A is incorrect. WPA2-EAP cannot be chosen for an ad hoc wireless network, as it requires RADIUS (Remote Authentication Dial- In User Service) server for authentication. Answer: D is incorrect. WPA-EAP cannot be chosen for an ad hoc wireless network, as it requires RADIUS (Remote Authentication Dial-In User Service) server for authentication.

Base64 encryption encoding, which can easily be decoded, is used in the basic authentication method. Answer: B is incorrect. The Md5 hashing technique is used in the digest authentication method. Answer: A is incorrect. The HMAC_MD5 hashing technique is used in the NTLMv2 authentication method. Answer: C is incorrect. DES (ECB mode) is used in the NTLMv1 authentication method.
