QA’ Built for PMs and Developers
@rainforestqa rainforest Us Team of 6 in SoMa All developers
YC S12
@rainforestqa rainforest Understanding risk
rainforest @rainforestqa Understand the trade off More secure generally means
more effort
@rainforestqa rainforest Risk vs Exposure
@rainforestqa rainforest High Risks Hot wallets / key storage Outgoing
payments Physically shipped items Reversible payments (e.g. chargebacks)
@rainforestqa rainforest …more risks Shared hosting / VPS / “physical”
security Staff
@rainforestqa rainforest Limiting Exposure Storing keys Hot wallets -> Cold
wallets, where poss Principle of least privilege
@rainforestqa rainforest What risks?
rainforest @rainforestqa Internet connected = hackable (Though, the NSA can
spy on you, even if you're not connected to the Internet)
@rainforestqa rainforest Top 5 >1k BTC hacks 46k / Linode
(Bitcoinica): exploit in admin area / staff —> hotwallet 11k / Bitcoin7: “hacked” 4.5k / BTC-E: Insecure external API key 4k / Kronos: self hack / backdoor 2.6k / Gox 2011: exploit in admin area
@rainforestqa rainforest Top 3 reasons:
@rainforestqa rainforest Badly configured servers / services
@rainforestqa rainforest Poorly written software
@rainforestqa rainforest Exploits
@rainforestqa rainforest Attack vectors Your service Your customers You &
your team
@rainforestqa rainforest Your service Domain Email Servers (app, db, etc)
Network External services Backups
@rainforestqa rainforest Domain DNS hijacking MITM attacks Doppelganger domains /
Typo-squatting Renewals
@rainforestqa rainforest HSTS Pinning / force-ssl Cloudflare, imho Firewall +
IDS
@rainforestqa rainforest Email DKIM / SPF Account state Clear email
policies Lockout policy
@rainforestqa rainforest Servers Shared / VPS / AWS Dedicated Co-lo
>
@rainforestqa rainforest OS + software updates Automate provisioning Hire pen-testing
Have a security program
@rainforestqa rainforest Transactions & locking (see Flexcoin / Poloniex)
@rainforestqa rainforest Network IDS / IDPS / HIDS Firewall (both
ways) -complex-
@rainforestqa rainforest External services Verify SSL certs Limit IPs Work
out what + who you can trust
@rainforestqa rainforest Backups Major security issue Encrypt them Test them
@rainforestqa rainforest Your customers Understand their behavior (Progressive) Account limits
Policies KYC
@rainforestqa rainforest Primer
@rainforestqa rainforest Educate yourself
@rainforestqa rainforest Pick secure by default tech
@rainforestqa rainforest 2FA
@rainforestqa rainforest Avoid shared servers
@rainforestqa rainforest Honey pots
@rainforestqa rainforest Automate deployment
@rainforestqa rainforest Use SSH keys, rotate them
@rainforestqa rainforest Use a Firewall
@rainforestqa rainforest Use an IDS
@rainforestqa rainforest Encrypt (and take!) backups
@rainforestqa rainforest Subscribe to security lists
@rainforestqa rainforest Do as little as possible
@rainforestqa rainforest Staff opsec
@rainforestqa rainforest Principle of least privilege
@rainforestqa rainforest Split your servers
@rainforestqa rainforest Or consider LXC / KVM
@rainforestqa rainforest Split your app
@rainforestqa rainforest Server: partitions + noexec + nosuid split running
users disable root remove packages SELinux
@rainforestqa rainforest Starting points Figure out your risk + exposure
Implement low hanging fruit Reduce surface Plan the rest
@rainforestqa rainforest Conclusions Simpler = better Understand your exposure and
limit it
