1. Right Answer: A
Explanation: Nowadays, computer security comprises mainly 'preventive' measures, like firewalls or an Exit Procedure. A firewall can be defined as a way of filtering network data between a host or a network and another network and is normally implemented as software running on the machine or as physical integrated hardware.
2. Right Answer: A,B,C,D,E
Explanation: The majority of software vulnerabilities result from a few known kinds of coding defects. Common software defects include buffer overflows, format string vulnerabilities, integer overflow, and code/command injection. Some common languages such as C and C++ are vulnerable to all of these defects. Languages such as Java are immune to some of these defects but are still prone to code/ command injection and other software defects which lead to software vulnerabilities.
3. Right Answer: B

4. Right Answer: A
Explanation: A buffer overflow is an anomalous condition where a process attempts to store data beyond the boundaries of a fixed length buffer. The result is that the extra data overwrites adjacent memory locations. The overwritten data may include other buffers, variables and program flow data.
5. Right Answer: C
Explanation: A buffer overflow is an anomalous condition where a process attempts to store data beyond the boundaries of a fixed length buffer. The result is that the extra data overwrites adjacent memory locations. The overwritten data may include other buffers, variables and program flow data.
