is new ccna harder.Ao attackers could exploit a SQL injection vulnerability to insert or "inject" SQL query statements into an application or database from the client as input data. This can then read sensitive data from the database, modify or delete database data, perform administrative operations on the database, and even execute operating system commands.Chapter 14.1. d. The question describes a timing attack.2. BoIPS is most afraid of encrypted traffic because it is impossible to assess whether such traffic poses a threat.3. Ao resource exhaustion is when an attacker sends out a "giant flow" with the intent of consuming the available resources of the target system, which will result in frequent alarms and will also prevent the target system from providing service.4. A. Modifying routing tables is not a traffic slicing attack technique.5. D. Proxies and in-line security detection devices help to block traffic fragmentation attacks. Protocols can be manipulated to "fool" security devices so that they cannot properly detect traffic. The TCP checksum and survival time protocols can be manipulated to look like something at first and then look like something else in order to fool the security defenses.C. C is the correct answer because doing so does not modify the legitimate traffic and behavior of HTTP. Answer A is incorrect because TCP injection attacks do not work on HTTPS traffic. Answer B is incorrect because TCP injection attacks do not modify legitimate traffic. Answer D does not provide enough detail. 7.C. C is the most accurate answer. The techniques in A and D do not involve netloading, meaning that no relevant attack is formed. Answer B is incorrect because doing so would be detected by most security devices. As per answer C, the net load of the traffic is simply changed to a different format, allowing the traffic to bypass detection by the security device, without modifying the content of the net load sent by the attacker. 8.8. Bo replacing ASCII with Unicode could lead to traffic substitution and insertion attacks.
