Which of the following is the best way to establish and verify the integrity of a file before copying it during an investigation?
Network administrators are often hesitant to patch the operating systems on CISCO router and switch operating systems, due to the possibility of causing network instability, mainly because of which of the following?
Many administrators are hesitant to upgrade the IOS on routers based on past experience with the code introducing instability into the network. It is often difficult to completely test an IOS software upgrade in a production environment because the monolithic kernel requires that the IOS be replaced before the device can be tested. Because of these reasons, IOS upgrades to resolve security flaws are often left undone in many organizations.
At the start of an investigation on a Windows system, the lead handler executes the following commands after inserting a USB drive. What is the purpose of this command? C:\ >dir / s / a dhsra d: \ > a: \ IRCD.txt
This command will create a text file on the collection media (in this case you would probably be using a USB flash drive) named IRCD.txt that should contain a recursive directory listing of all files on the desk.
What attack was indicated when the IDS system picked up the following text coming from the Internet to the web server?
select user, password from user where user= ''jdoe'' and password= 'myp@55!' union select ''text'',2 into outfile ''/tmp/file1.txt'' - - '
An example of manipulating SQL statements to perform SQL injection includes using the semi-colon to perform multiple queries. The following example would delete the users table:
Username: ' or 1=1; drop table users; - -
Password: [Anything]
Which could be described as a Threat Vector?
A threat vector is the method (crafted packet) that would be used to exercise a vulnerability (fragmentation to bypass IDS signature). An unpatched web server that is susceptible to XSS simply describes a vulnerability (unpatched) paired with a specific threat (XSS) and does not touch on the method to activate the threat. Similarly, the coding error that allows remote code execution is simply describing the pairing of a vulnerability with a threat, respectively. The botnet is an unspecified threat; there is no indication of how the threat was activated (or it's intention/capabilities; the threat).
