You Should Know:
1. Cloud Security Posture Management (CSPM) Enforcement
With CoreStack securing $50M for cloud governance, automating cloud security configuration is paramount. Misconfigured cloud storage remains a primary attack vector.
Verified Command/Code Snippet:
AWS CLI command to scan for and make public S3 buckets private aws s3api list-buckets --query "Buckets[].Name" --output text | tr '\t' '\n' | while read bucket; do if aws s3api get-bucket-acl --bucket "$bucket" --query "Grants[?Grantee.URI=='http://acs.amazonaws.com/groups/global/AllUsers']" --output text | grep -q "ALL"; then echo "Making bucket $bucket private" aws s3api put-bucket-acl --bucket "$bucket" --acl private fi done
Step-by-step guide:
This bash script utilizes AWS CLI to systematically identify and remediate publicly accessible S3 buckets. First, it lists all S3 buckets in the account. Then, for each bucket, it checks if any grant provides access to the global “AllUsers” group. If public access is detected, it immediately applies private ACL settings. Run this script regularly through cron jobs or integrate it into your CI/CD pipeline for continuous compliance monitoring.
2. AI Security Testing and Validation
As Obot AI raises $35M for AI security, validating AI model integrity becomes critical. Adversarial attacks against machine learning models represent a growing threat surface.
Verified Command/Code Snippet:
import tensorflow as tf
import numpy as np
Basic model robustness test against adversarial inputs
def test_model_robustness(model_path, test_data, epsilon=0.01):
model = tf.keras.models.load_model(model_path)
x_test, y_test = test_data
Generate adversarial examples using Fast Gradient Sign Method
with tf.GradientTape() as tape:
tape.watch(x_test)
prediction = model(x_test)
loss = tf.keras.losses.categorical_crossentropy(y_test, prediction)
gradient = tape.gradient(loss, x_test)
adversarial_examples = x_test + epsilon tf.sign(gradient)
adversarial_predictions = model(adversarial_examples)
Compare accuracy drop
original_accuracy = tf.keras.metrics.categorical_accuracy(y_test, model(x_test))
adversarial_accuracy = tf.keras.metrics.categorical_accuracy(y_test, adversarial_predictions)
return f"Accuracy drop: {np.mean(original_accuracy) - np.mean(adversarial_accuracy):.4f}"
Step-by-step guide:
This Python script implements basic adversarial testing using TensorFlow. It loads a pre-trained model, generates adversarial examples using the Fast Gradient Sign Method (FGSM), then measures the accuracy degradation. Security teams should integrate such tests into their model validation pipelines, running them whenever models are updated. The epsilon parameter controls perturbation strength—start with 0.01 and increase based on your robustness requirements.
3. Identity Threat Detection and Response
With Glide Identity securing $20M, monitoring identity infrastructure for anomalies is essential. Attackers increasingly target identity providers and authentication systems.
Verified Command/Code Snippet:
PowerShell script to detect anomalous authentication patterns in Windows Event Logs
Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4624,4625} |
Where-Object {
$logonType = $<em>.Properties[bash].Value
$account = $</em>.Properties[bash].Value
$sourceIP = $<em>.Properties[bash].Value
Alert on unusual logon types from unusual locations
($logonType -in @(2,3,10) -and $sourceIP -notmatch "^(192.168|10.|172.(1[6-9]|2[0-9]|3[0-1]))") -or
(($</em>.Id -eq 4625) -and $_.TimeCreated -gt (Get-Date).AddHours(-1))
} | Select-Object TimeCreated, Id, @{Name='Account';Expression={$account}}, @{Name='SourceIP';Expression={$sourceIP}}
Step-by-step guide:
This PowerShell script queries Windows Security logs for successful (4624) and failed (4625) logon events. It filters for network logon types (2,3,10) originating from non-RFC1918 IP spaces, plus all failed logons within the last hour. Deploy this as a scheduled task running hourly, with output redirected to your SIEM or security monitoring system. Tune the IP ranges to match your normal administrative access patterns.
4. Zero Trust Network Access Implementation
As Keycard raises $38M for device identity, implementing device-level authentication becomes critical for zero-trust architectures.
Verified Command/Code Snippet:
iptables rules enforcing device certificate validation for network access !/bin/bash Create dedicated chain for zero-trust device enforcement iptables -N ZERO_TRUST_DEVICE iptables -A FORWARD -j ZERO_TRUST_DEVICE Allow established connections iptables -A ZERO_TRUST_DEVICE -m state --state ESTABLISHED,RELATED -j ACCEPT Drop connections from devices without valid client certificates iptables -A ZERO_TRUST_DEVICE -p tcp --dport 443 -m connmark --mark 0x0 -j DROP iptables -A ZERO_TRUST_DEVICE -p tcp --dport 22 -m connmark --mark 0x0 -j DROP Accept marked connections (devices with valid certificates) iptables -A ZERO_TRUST_DEVICE -m connmark --mark 0x1 -j ACCEPT
Step-by-step guide:
This bash script creates iptables rules that enforce device-level authentication before granting network access. The rules assume that a separate process (like a certificate validation service) marks connections from validated devices with connmark 0x1. Connections without this mark to critical services (HTTPS/SSH) are automatically dropped. Implement these rules on your network gateways and update them regularly as device certificates are issued or revoked.
5. API Security Testing and Hardening
With Descope’s $35M seed round focusing on authentication infrastructure, API security testing becomes non-negotiable.
Verified Command/Code Snippet:
OWASP ZAP API Security Scan automation docker run -v $(pwd):/zap/wrk/:rw -t owasp/zap2docker-stable zap-api-scan.py \ -t https://api.yourtarget.com/openapi.json \ -f openapi \ -r api_security_report.html \ -c zap_api_scan.conf \ -x http://proxy:8080 \ -U "Security-Scanner" \ -a "-config scanner.attackOnStart=true -config api.disablekey=true"
Step-by-step guide:
This command runs the OWASP ZAP API security scanner in a Docker container, testing REST APIs against common vulnerabilities. The -t parameter specifies the OpenAPI specification URL, while -c allows passing a configuration file for custom rules. Run this scan regularly in your staging environment, ideally as part of your CI/CD pipeline. Review the generated HTML report for issues like broken authentication, excessive data exposure, or injection vulnerabilities.
6. Container Security Hardening
As Chainguard’s $280M funding highlights supply chain security, container runtime protection becomes essential.
Verified Command/Code Snippet:
Kubernetes Pod Security Context hardening apiVersion: v1 kind: Pod metadata: name: security-context-demo spec: securityContext: runAsNonRoot: true runAsUser: 1000 runAsGroup: 3000 fsGroup: 2000 seccompProfile: type: RuntimeDefault containers: - name: sec-ctx-demo image: nginx:1.21 securityContext: allowPrivilegeEscalation: false capabilities: drop: - ALL readOnlyRootFilesystem: true
Step-by-step guide:
This Kubernetes pod specification implements multiple container security best practices. The security context ensures the container runs as a non-root user, drops all Linux capabilities, prevents privilege escalation, mounts the root filesystem as read-only, and applies the default seccomp profile. Apply these settings to all your production pods to significantly reduce the attack surface. Test thoroughly as some applications may require specific capabilities to function correctly.
7. Incident Response Automation
With Prelude’s $16M funding for security operations, automating initial incident response accelerates containment.
Verified Command/Code Snippet:
!/usr/bin/env python3
Automated incident response: isolate compromised host
import subprocess
import requests
def isolate_host(host_ip, firewall_manager):
Block host at network level
subprocess.run(['iptables', '-A', 'INPUT', '-s', host_ip, '-j', 'DROP'])
subprocess.run(['iptables', '-A', 'OUTPUT', '-d', host_ip, '-j', 'DROP'])
Notify SIEM and ticketing system
siem_data = {'event': 'host_isolation', 'host_ip': host_ip, 'action': 'blocked'}
requests.post('https://siem.company.com/api/events', json=siem_data)
ticket_data = {'title': f'Host {host_ip} isolated', 'priority': 'high'}
requests.post('https://ticketing.company.com/api/incidents', json=ticket_data)
return f"Host {host_ip} isolated and stakeholders notified"
Step-by-step guide:
This Python script automates the initial response to a compromised host. When triggered (manually or via SIEM integration), it immediately blocks all network traffic to and from the host using iptables, then creates audit trails in both SIEM and ticketing systems. Customize the API endpoints to match your security infrastructure. Consider adding additional actions like disabling user accounts or triggering forensic data collection based on your incident response playbooks.
