Handling
Description
- There was a large incident in a water treatment facility. It required response from various CSIRT teams, providing live system analysis, forensics, malware analysis, ICS expertise and other roles. You overheard a guy from team A talking about choosing a containment strategy. A guy from team B talking about containment and eradication stage. A guy from team C talking about evidence gathering and handling. Identify which two teams are likely using the same incident handling methodology. 
- In one of the two leading standards on cybersecurity incident handling, there is a chapter Access Control under Type of incidents. Looking at the second word of the text from that chapter, how many letters are there? 
- In ENISA incident guide table of contents, which chapter has the same colour as the iconic object on the picture on the same page? Answer in uppercase, no spaces. 
- In the same document, there is a diagram which looks like a downward pointing arrow. What is the stage on the tip of the arrow? Answer in uppercase, no spaces. 
- SANS methodology for incident handling specifically mentions some operating systems. Out of those, which is the least frequently mentioned one? Answer in uppercase, no spaces. 
Flag format: answers, separated by dash:
- two letters from the first question, i.e. one of AA, AB, AC, BC (two letters, uppercase, nothing else)
- number answering the second question
- name of the chapter, all letters uppercase, no spaces (if any).
- stage, all letters uppercase, no spaces (if any)
- name of the operating system
For example, if your answers were
- CD (of course there is no letter D, are we clear?)
- 9
- NAMEOFTHECHAPTER
- SOMESTAGE
- BEOS
Then the flag will be
CD-9-NAMEOFTHECHAPTER-SOMESTAGE-BEOS
Submission limit is 20
Solution
- NIST SP 800-61r2; 3.3.1 Choosing a Containment Strategy and 3.3.2 Evidence Gathering and Handling thats AC
- ISO/IEC 27035-1:2023, Annex B, B.1 Type of incidents, B.1.5 Access control; Second word is access
- ENISA - Good Practice Guide for Incident Management, iconic object
 being a red fire truck, the chapter that is red in ToC is being a red fire truck, the chapter that is red in ToC isWorkflows. 
- Same document,
 Figure 6 - Incident handling workflow, tip of the arrow is Figure 6 - Incident handling workflow, tip of the arrow isIMPROVEMENT PROPOSALS.
- Here I was not exactly sure which document it should be, I went based on Incident Handler’s Handbook, looking for operating systems Linuxappeared to be mentioned but very few times.
AC-6-WORKFLOWS-IMPROVEMENTPROPOSALS-LINUX
Colors of the rainbow
Description
- Which two of these colors are most related to common criteria? (uppercase, comma separated) RED / ORANGE / YELLOW / GREEN / BLUE / INDIGO / VIOLET 
- The ENISA incident handling book, which we already mentioned, has this nice truck. What is the color of the longest part of the truck? BLUE / RED / GRAY / BLACK / WHITE 
- The NIST standard has a different first responder’s truck on some diagram. Which is true: 1 it is a police van 2 the driver of the truck is a bald male 3 the driver of the truck is a young female 4 the truck is a 6-wheeler 5 the truck looks at the shield and a sword 6 the truck travels towards the tree 
Flag format: answers, separated by dash:
- colors from the list, uppercase, comma separated, in the order from the list.
- color from the list, uppercase
- the number of the correct statement
For example, if your answers were
- RED,CYAN
- GREEN
- 9
Then the flag will be RED,CYAN-GREEN-9
Submission limit is 20 flags
Solution
- One color I was able to identify as related to Common Criteria was RED. I am not sure where the ORANGE was supposed to be found but guess work helped here.inshallah!
- ENISA - Good Practice Guide for Incident Management, the longest part being the ladder which is white.
- NIST SP 800-61r3; 2.1. Incident Response Life Cycle Model; “5 the truck looks at the shield and a sword”

RED,ORANGE-WHITE-5
