Schedule

Before you start

Log in

Your slip has your own credentials. Nobody shares a login; working in pairs on one login (one drives, one checks) is fine.

In Center, switch the UI to EN on first login. Your Center organisation team-NN has one customer: Isla Mercantile Group (team-NN). traineeNN and kNN are both members of team-NN and work on that same customer.

Shared environment

• One Insights for the whole group. Tags are shared: every team sees the others' tags appear.
• Custom views are shared: every view you save is in everyone's list. Prefix the name with your team or login (webshop — chain); do not change or delete a view you did not create.
• There is no personal reset. Do not delete data, uploads or tags you did not create.
• Tag rule: tag only hosts of your own app, one person per host, never remove tags you did not set. Full convention: Tag convention.
• Center and the Kartis pages keep state per team customer: register upload, posture runs, finding status and labels are shared by traineeNN and kNN of the same team, and invisible to other teams.
• Traffic replays (probe chapters) are started by the trainer. You need no shell on the server.
• AI: the Insights Chat is available in the Insights blocks. The Kartis pages have no AI.

Queries, live checks and templates

Queries

Run these through the Insights Chat. The Chat only accepts SELECT/WITH and rejects any query containing words such as INSERT, UPDATE, DELETE, ALTER, CREATE, REPLACE, SET anywhere in the text.

A.1 Chain view (I-TAG.2, I-M11)

Replace app:webshop with your app.

SELECT
    hostname,
    toString(any(ipv4))                                  AS ip,
    arrayDistinct(groupArrayArray(tags))                 AS all_tags,
    arrayFirst(t -> startsWith(t, 'tier:'),  all_tags)   AS tier,
    arrayFirst(t -> startsWith(t, 'owner:'), all_tags)   AS owner,
    anyLast(security_level)                              AS level,
    multiIf(level = 'insecure', 1, level = 'weak', 2,
            level = 'secure', 3, level = 'recommended', 4, 5) AS ladder_rank
FROM hosts
GROUP BY hostname
HAVING has(all_tags, 'app:webshop')
ORDER BY ladder_rank, tier

Live checks

Against the Isla public sites. Always pass -servername: web-b routes by SNI, and a client without SNI lands on pay. OpenSSL 3 needs @SECLEVEL=0 in the cipher string for 3DES and TLS 1.0; drop :@SECLEVEL=0 on LibreSSL (openssl version tells you which one you have). Some Linux distributions block TLS 1.0 in the system crypto policy even with @SECLEVEL=0; B.1b shows whether yours does. If it does, use testssl.sh or pair with someone whose client can.

B.1 3DES on pay (I-M2.3, K-1.6, C6.1)

openssl s_client -connect pay.isla.edu.eoncore.net:443 -servername pay.isla.edu.eoncore.net \
  -tls1_2 -cipher 'DES-CBC3-SHA:@SECLEVEL=0' </dev/null

B.1b Control: can your client speak TLS 1.0? (C6.2, K-1.5, I-M11)

openssl s_client -connect pay.isla.edu.eoncore.net:443 -servername pay.isla.edu.eoncore.net \
  -tls1 -cipher 'DEFAULT:@SECLEVEL=0' </dev/null

Handshake succeeds: your client can test TLS 1.0. no protocols available or a failure before any server answer: your client refuses TLS 1.0, and B.2 proves nothing.

B.2 TLS versions on intranet (K-1.5, C6.2, I-M11)

openssl s_client -connect intranet.isla.edu.eoncore.net:443 -servername intranet.isla.edu.eoncore.net -tls1 -cipher 'DEFAULT:@SECLEVEL=0' </dev/null
openssl s_client -connect intranet.isla.edu.eoncore.net:443 -servername intranet.isla.edu.eoncore.net -tls1_2 </dev/null

B.3 Certificate expiry (I-M11, C6)

openssl s_client -connect intranet.isla.edu.eoncore.net:443 -servername intranet.isla.edu.eoncore.net </dev/null \
  | openssl x509 -noout -enddate

Record every check you use as evidence: date, command, result.
