should i keep records of attack findings? how long should i store them? will i get in trouble for deleting them later?

keep evidence for 6 years, even if the complaint drops. like keep it encrypted in a safe etc. if the prosecutor says its done you can delete it but waiting 6 years is safer. forensic disk, malware samples — restricted access...

Evidence preservation: 1) Disk image (dd if=/dev/sda | openssl enc -aes-256-cbc -out image.enc), 2) Integrity verification (SHA-256 hash documented, recalculate periodically), 3) Storage (encrypted partition, external hard drive, encrypted cloud), 4) Access control (key escrow: two-person rule for access), 5) Audit trail (access logs with timestamps), 6) Regular integrity checks (quarterly hash re-verification). Retention calendar: criminal case 6 years (from judgment), civil/administrative 5 years (from resolution), deletion procedure (secure wipe, certificate of destruction). Malware sample handling: isolated VM, no internet connection, physical lock on device.

keep the disk image encrypted store it in a safe. evidence min 6 years — wait even if the prosecutor says go ahead. malware samples in a locked room nobody touch and anyway even if the complaint is dropped there's a risk it could be reopened...

Evidence management policy: Identification (tag all evidence with case number, date, handler), Preservation (encryption, access controls, integrity verification), Retention (legal hold dates, retention calendar), Destruction (secure deletion method, sign-off approval, certificate of destruction). Legal timeline: statute of limitations (TCK Article 71: 5 or 6 years depending on the crime), civil action limitation (5 years for damage claims). Documentation: chain of custody form (every handoff recorded), evidence log (inventory of all items), access log (who viewed evidence when). Special handling: classified information (government security clearance required), victim confidentiality (redacted evidence if disclosure risks safety).

Absolutely. If I were to add anything: The answer varies greatly by industry; there is no one-size-fits-all rule.

If you scold false alarms nobody will report again.

Saved. If the notification path is long, notifications don't arrive; missing notifications mean delayed incident detection.

Hope this helps.

I completely agree. Mistakes made on the evidence retention side are usually reversible but expensive.

Proven by experience.

There's a part I don't understand. An untested backup is not a backup.

Of course, it varies if your situation is different.

There's also a measurement aspect to this. If 2FA is on, a stolen password alone is useless.

That's all, sorry if I went on too long.

There's a part I don't understand. Security isn't absolute; it's about making attacks not worth the effort.

I agree, and I'd like to emphasize that. Hasty decisions become decisions you have to fix six months later.

Solutions that work at a small scale collapse when you grow; I learned this late. Of course, it varies if your situation is different.

I'm curious too.

Following. People defend habits, not processes. Resistance comes from there.

My questions are cleared up thanks.

There's a common mistake people make when doing this. Trying to do this alone is the most expensive way.

Of course it varies if your situation is different.

I didn't know that.

If you're going this route, sort this out first. If you get three different answers on a topic, the question was asked wrong.

Taking notes for two weeks yields better results than a six-month estimate.

I've been down this road let me tell you. If it's your first time, start small; scaling comes later.
