- In Check Point R80, you can combine manual + automatic NAT
- Manual Destination NAT
- Public IP → Internal web server (port 80)
- Automatic Hide NAT
- Internal server → Internet (outbound traffic)
- Same server can use:
- Static NAT (inc...
- In Check Point R80, NAT controls how private and public networks communicate
- Many internal devices → one public IP
- Typically uses:
- Gateway’s external IP
- Internet browsing
- Outbound traffic
- In Check Point R80, policy packages allow you to organize rules per gateway
- Avoid one large, complex policy
- Assign specific rule sets to each firewall
- Firewall 1 → Internal traffic rules
- Firewall 2 → DMZ or external access rules ...
- In Check Point R80, rules can depend on time conditions
- Create time objects (e.g., 12 PM → 12 AM)
- Attach them to firewall rules
- Allow admin access only during work hours
- Block risky services at night
- In Check Point R80, snapshots act as a full system backup
- Capture:
- File system
- Configuration
- Management database
- Before:
- Upgrades
- Major changes
- The primary management tool in Check Point R80 is SmartConsole
- Access Gaia OS WebUI
- Download SmartConsole client
- Install on your local machine
- Connect to:
- Security Management Server IP
- Authenticate using admin...
- This lesson introduces Check Point R80
- Focus: building a distributed deployment
- Security Management Server
- Controls policies
- Centralized management
- Security Gateway (Firewall)
- Enforces security rules
- Handles traffic filtering
- The episode provides 7 ready-to-use starter projects for popular frameworks:
- Flask
- Express (Node.js)
- .NET
- Django
- Ruby on Rails
- Golang
- Laravel
- Each project includes:
- Dockerfile
- docker-compose.yml
- docker-compose up → Start services
- docker-compose build → Build images
- docker-compose stop → Stop containers
- docker-compose ps → List running containers
- docker...
- Docker Compose is a tool used to:
- Define
- Run
- Manage
- Core configuration file written in YAML
- Uses version 3 syntax
- Default bridge network:
- Basic isolation
- Requires manual IP handling
- Custom bridge network (recommended):
- Automatic DNS resolution
- Containers communi...
- Uses Dockerfile instructions
- Leverages layer caching → faster rebuilds
- Used for version control
- Prep...
- This lab uses a simple microservices setup:
- Flask web application (frontend/API)
- Redis (backend datastore)
- Key idea:
- Each service runs in its own container
- They communicate over a Docker network
- You start by running a simple container using Docker
- Behind the scenes:
- Docker CLI sends a command
- Docker Daemon processes it
- Image is pulled from Docker Hub
- Key insight:
- Docker only downloads missing layers → future runs are much faster
- Docker is available in two main editions:
- Free and open-source
- Suitable for:
- Individual developers
- Small teams
- Production workloads in many cases
- Paid version
- Includes:
- Official support
- Certified images
- Advanced security fea...
- A Virtual Machine (VM) stack includes:
- Infrastructure (hardware)
- Host Operating System
- Hypervisor (like VMware or Hyper-V)
- Guest Operating System (inside each VM)
- Applications
- Key characteristics:
- Each VM runs a full OS
- Strong isolation
- Higher resource usage (CPU, RAM, disk)
- Slo...
- This course is hands-on by design
- You’re expected to:
- Run terminal commands
- Write your own Dockerfiles
- Follow along step-by-step
- The goal:
- Move from theory → practical Docker usage with Docker
- A downloadable package includ...
- Developers often face:
- “It works on my machine” issues
- Environment inconsistencies across teams
- Heavy, slow virtual machines
- Docker solves this by:
- Packaging applications with their dependencies
- Running them consistently across any system
- Traditional...
- Goal:
- Allow approved devices to enroll and be tracked
- Secure approach:
- Use mutual TLS (mTLS) or signed tokens (e.g., short-lived JWTs)
- Issue each device a unique ID + certificate/secret during provisioning
- Validate:
- Device identity
- Request signature <...
- Core idea:
- Create authorized admin users in your database
- ❌ What to avoid:
- Using weak hashing like MD5 (easily cracked)
- ✅ Best practice:
- Use PHP:
- password_hash() (bcrypt by default)
- password_verify()
- Use PHP:
- Additional protections:
- ...
