TL;DR — ENISA Threat Landscape 2025 spotlights two realities engineers feel daily: ransomware is still the most disruptive risk, and DDoS/hacktivism drives incident volume. Below are 10 dev-team fixes you can ship this sprint—with code, runbooks, and evidence-ready artifacts your auditors (and leadership) will trust.
Fix 1 — Immutable/offline backups + restore-time SLOs (with proof)
Why: Ransomware remediation lives or dies on restore speed and clean snapshots.
Do this:
(a) Enable object-lock immutability on backup buckets (AWS example)
# Create versioned, locked backups bucket
aws s3api create-bucket --bucket my-backups --region us-east-1
aws s3api put-bucket-versioning --bucket my-backups --versioning-configuration Status=Enabled
aws s3api put-object-lock-configuration \
--bucket my-backups \
--object-lock-configuration '{
"ObjectLockEnabled": "Enabled",
"Rule": {"DefaultRetention": {"Mode": "COMPLIANCE", "Days": 30}}
}'
(b) Prove restore SLO with an automated drill
#!/usr/bin/env bash
# restore-drill.sh: measure RTO and verify integrity
set -euo pipefail
START=$(date +%s)
aws s3 cp s3://my-backups/db-dump-latest.sql.zst /tmp/
unzstd -f /tmp/db-dump-latest.sql.zst -o /tmp/db.sql
psql "$PG_URL" -c "DROP DATABASE appdb;" || true
createdb appdb
psql appdb < /tmp/db.sql
CHECK=$(psql appdb -tAc "SELECT count(*)>0 FROM critical_table")
END=$(date +%s)
echo "RTO_seconds=$((END-START)) integrity_ok=$CHECK" | tee restore-metrics.log
Store
restore-metrics.login your evidence bundle.

Fix 2 — Enforce MFA on admin paths and sensitive ops
Why: Admin portals and critical flows are top-tier initial access.
NGINX + OAuth2 proxy (SSO/MFA) in front of /admin
location /oauth2/ {
proxy_pass http://oauth2-proxy;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
location = /admin {
return 302 /oauth2/start?rd=$scheme://$host$request_uri;
}
location /admin/ {
auth_request /oauth2/auth;
error_page 401 = /oauth2/start;
proxy_pass http://app_backend;
}
Extra belt-and-suspenders (Express middleware)
// admin-mfa.js
module.exports = (req, res, next) => {
if (!req.user || !req.user.mfa_passed) return res.status(401).end();
next();
};
Fix 3 — EDR isolation playbooks you can actually run
Why: When ransomware triggers, seconds matter. Pre-stage host isolation.
Windows rapid isolation (PowerShell)
# isolate.ps1
Get-NetAdapter | Where-Object {$_.Status -eq "Up"} | Disable-NetAdapter -Confirm:$false
New-NetFirewallRule -DisplayName "Block All Outbound" -Direction Outbound -Action Block
Stop-Service -Name "LanmanServer" -Force
Linux emergency egress block
iptables -P OUTPUT DROP
systemctl stop smb || true
systemctl stop nfs || true
Keep signed playbooks in a versioned repo; export execution logs for your evidence pack.
Fix 4 — Tabletop exercises with evidence that sticks
Why: Auditors ask: Show me you practiced. Give them artifacts.
# Ransomware Tabletop (Evidence)
Date: 2025-11-05
Scope: Finance app, prod-like env
Injects: EDR alert -> lateral movement -> exfil attempt
Decisions: isolate host X, rotate secrets, restore T-24h snapshot
Metrics: MTTD=6m, MTTR=68m, Comms SLA met
Follow-ups: blocklist IoCs, patch CVE-XXXX-YYYY
Sign-off: IR Lead, SRE Lead
Fix 5 — Autoscaling + provider-side DDoS mitigation
Why: Volumetric DDoS: absorb and deflect; don’t brute-force it.
GCP Cloud Armor rate-based rule (provider-side)
# cloud-armor.yaml
name: rate-limit-global
description: "Global RPS limit"
action: throttled
rateLimitOptions:
rateLimitThreshold:
count: 200
intervalSec: 60
conformAction: enforce
match:
versionedExpr: SRC_IPS_V1
config: {}
gcloud compute security-policies import rate-limit-global --source=cloud-armor.yaml
AWS autoscaling group (Terraform snippet)
resource "aws_autoscaling_group" "web" {
desired_capacity = 6
min_size = 4
max_size = 24
health_check_type = "ELB"
target_group_arns = [aws_lb_target_group.web.arn]
}
Fix 6 — WAF rate limits and token buckets (edge and origin)
Why: App-layer DDoS and brute force exhaust threads, not bandwidth.
NGINX token bucket
limit_req_zone $binary_remote_addr zone=perip:10m rate=5r/s;
server {
location /login {
limit_req zone=perip burst=20 nodelay;
proxy_pass http://app_backend;
}
}
Pair with provider WAF (Cloud Armor/Cloudflare/AWS WAF) for layered defense.
Fix 7 — Canary endpoints for fast triage and auto-scale signals
Why: Cheap, high-signal checks to detect brownouts early.
// canary.go
package main
import ("net/http"; "os")
func main() {
http.HandleFunc("/readyz", func(w http.ResponseWriter, r *http.Request) {
if os.Getenv("DB_OK") != "1" { w.WriteHeader(503); return }
w.WriteHeader(204)
})
http.ListenAndServe(":8080", nil)
}
Hook /readyz into HPA/ASG health checks.
Fix 8 — Error budgets tied to incident runbooks (burn-rate alerts)
Why: Keep user-impact guardrails during DDoS or patch windows.
# slo.yaml (Prometheus/Sloth-style)
service: "checkout"
slo:
objective: 99.9
window: 30d
indicator: { ratio: { errors: "sum(rate(http_5xx[5m]))", total: "sum(rate(http_requests_total[5m]))" } }
alerts:
- name: "fast-burn"
expr: "burn_rate_5m > 14 and burn_rate_1h > 14"
for: 15m
runbook: "https://runbook.local/ddos"
Fix 9 — Asset & service inventory you can diff daily
Why: You can’t patch or shield what you don’t know exists.
# inventory_aws.py
import boto3, csv
ec2 = boto3.client("ec2")
elbv2 = boto3.client("elbv2")
inst = ec2.describe_instances()
lbs = elbv2.describe_load_balancers()
rows=[]
for r in inst["Reservations"]:
for i in r["Instances"]:
rows.append({"type":"ec2","id":i["InstanceId"],"public":i.get("PublicIpAddress")})
for lb in lbs["LoadBalancers"]:
rows.append({"type":"alb","id":lb["LoadBalancerArn"],"dns":lb["DNSName"]})
with open("inventory.csv","w",newline="") as f:
w=csv.DictWriter(f,fieldnames=rows[0].keys()); w.writeheader(); w.writerows(rows)
print("Wrote inventory.csv")
Schedule nightly and diff for surprises.
Fix 10 — KEV-driven patching to seed your backlog
Why: Prioritize vulns actively exploited in the wild.
# kev_sync.py
import requests, json, datetime
KEV_URL = "https://www.cisa.gov/sites/default/files/feeds/known_exploited_vulnerabilities.json"
kev = requests.get(KEV_URL, timeout=20).json()
today = datetime.date.today().isoformat()
prio = [cve for cve in kev["vulnerabilities"] if cve["vendorProject"] in {"Microsoft","JetBrains","Atlassian"}]
with open(f"kev-{today}.json","w") as f: json.dump(prio, f, indent=2)
print(f"KEV items: {len(prio)}")
Feed kev-*.json into your issue tracker with labels like priority:kev.
