Beth is creating a new cyber security incident response team (CSIRT) and would like to determine the appropriate team membership. Which of the following groups would she normally include? (select all that apply) a. information security b. law enforcement c. senior management d. public affairs

A,C,D

Nancy is leading an effort to modernize her organizations anti-malware protection, and would like to add endpoints detection and response (EDR) capabilities. Which of the following actions are normally supported by EDR systems? Select all that apply. a Analyzing and point memory file system, and network activity for signs of malicious activity b Automatically isolating possible malicious activity to contain the potential damage c Conducting simulated fishing campaigns d Integration with threat intelligence sources

ABD EDR does not do phishing campaigns they do however analyze endpoint memory filesystem network activity for signs of malicious activity; isolating possible malicious activity to contain the potential damage, integrate with threat intelligence sources and other IR mechanisms

Which of the following would normally be considered an example of a disaster when performing disaster recovery planning? (Select all that apply) a. hacking incident b. flood c. fire d. terrorism

All of the above - disaster is anything that disrupts normal IT operations. natural or manmade.

You are performing an investigation into a potential bot infection on your network and want to perform a forensic analysis of the information that passed between different systems on your network on those on the Internet. You believe that the information was likely encrypted. You are beginning your investigation after the activity concluded, would be the best and easiest way to obtain the source of this information? A package captures B NetFlow data c intrusion detection system logs d Centralize authentication

B NetFlow data contains info on source, destination and size of all network communications. packet capture would provide relevant info, but it must be captured during suspicious activity and cannot be re-created after the fact. unless it was doing 100% packet capture which is rare. IDS would not contain relevant info because it is encrypted traffic and would not match IDS signatures centralized authentication records would not contain info about network traffic

Tonya is collecting evidence from a series of systems that were involved in a cyber security incident. A colleague suggests that she use a forensic disk controller for the collection process. What is the function of this device? a. Masking error conditions reporting by the storage device. b. transmitting write commands to the storage device c. intercepting and modifying or discarding commands sent to the storage device d. preventing data from being returned by a read operation sent to the device.

C - forensic disk controller performs four functions 1. write blocking (intercept write commands and prevents modification) 2. returning data requested by a read operation 3. returning access-significant information from device 4. reporting errors from device to host

Allie is responsible for reviewing authentication logs on her organization's network. She does not have the time to review all logs, so she decides to choose only records where there have been four or more invalid authentication attempts. What technique is Allie using to reduce the size of the pool? A. Sampling B. Random selection C. Clipping D. Statistical analysis

C. Clipping sampling uses statistical techniques clipping uses threshold values to select those records

Glenda would like to conduct a disaster recovery test and is seeking a test that will allow a review of the plan with no disruption to normal information system activities and as minimal a commitment of time as possible. What type of test should she choose? A. Tabletop exercise B. Parallel test C. Full interruption test D. Checklist review

D. Checklist review - least disruptive table top they come together and can impact operations parallel test, the team actually activates the disaster recovery site for testing, but the real site remains operational full interruption test is self explanatory

incident data sources

IDS/IPS Firewalls Authentication systems integrity monitors vulnerability scanners system event logs NetFlow records Antimalware packages

Kandace is designing a back up strategy for her organization file server. She would like to perform a back up every weekday that has the smallest possible storage footprint. What type of back up so she perform a Incremental backup b Full backup c Differential back up d Transaction log back up

Incremental backup - only data modified since the most recent incremental a differential back up all data modified since last full backup transaction log back up is for database servers and not for file servers

lessons learned

NIST has questions how well did staff and mgt perform were documented procedures followed were those procedure adequate? did any actions inhibit recovery effort? what would staff do differently? how could info sharing improve what could precent similar incidents what should the org watch for what tools should be used for future incidents facilitator and leader should document and approve changes incident summary report more technical report

asset management

request hardware from IT team inventory once it is placed matches to inventory and adds serial numbers some on is assigned to it then possessed by someone old one to someone else update inventory DATA is critical IT management systems automate comparing to the network

Segmentation vs isolation

segmentation moves to diff vlans isolation moves to an entire different network removal is not connected to network - most secure but attacker knows

embedded deices

special purpose computers found in smart devices, businesses and industrial settings CARS dozens to 100s of embedded systems climate control, GPS, wealth of information thermostat for time of death

Mobile Device Forensics

Preservation and analysis of cell phones, smart phones, and satellite navigation (GPS) systems mobile devices are typically protected by strong encryption

Incident response plan elements

statement of purpose strategies and goals for incident response approach to incident response (who is responsible and authority) communication iwth other groups senior leadership approval

simulation

they discus how they respond

validation process

verify the secure configuration of every system - can be automated run vulnerability scans perform account and permission reviews verify that system are logging and communicating information to the SIEM
