Security Operating Platform - Answer-- Provide full visibility
- Reduce the attack surface
- Prevent all known threats, fast
- Detect and prevent new, unknown threats with automation
Router, Hub, Switches - Answer-Hub => Connects multiple devices on a LAN. Traffic
sent to hub is broadcasted out of all ports (security risk).
Switch => Intelligent hub that uses physical addresses to forward data packets to
devices on a network.
Router => Devices that send data packets to destination networks along a network path
using logical addresses.
VLAN - Answer-A subnetwork that groups together collections of devices that reside on
separate LANs.
Used to logically partition devices that frequently talk to one another.
Routed vs. Routing Protocols - Answer-Routed => Manage packets with routing
information that enables those packets to be transported across networks.
Routing => Defined at the network layer and specify how routers communicate with one
another.
Static Routing - Answer-Routes are created and updated manually on a router or other
network device.
Low bandwidth requirements and built-in security
Dynamic Routing - Answer-Learn new routes and determine the best route to a
destination automatically.
Distance-vector => Makes decisions based on distance (hop count) and vector.
Link state => Every router calculates a complete map
Path vector => Similar to distance-vector but without scalability issues. (Ex. BGP, used
by ISPs, NSPs, and large private IP networks)
, RIP (Routing Information Protocol) - Answer-Example of a distance-vector routing
protocol
Implements a hop limit of 15 to prevent loops
Split horizon: Prevents a router from advertising a route back out through the same
interface
Triggered updates: Update sent immediately when change is detected.
Route poisoning: Sets hop count on a bad route to 16
Holddown timers:
SD-WAN - Answer-Virtualized service that connects and extends enterprise networks.
Simplicity
Reduced Cost
Improved performance
DNS - Answer-Translates domain names into IP addresses
A/AAAA => Domain to IP (IPv4, IPv6)
CNAME => Domain to another hostname
MX => Hostname of email servers
ARP - Answer-Translates IP address to MAC address
NAT - Answer-Virtualizes IP addresses by mapping private IP address assigned to
internal devices to public IP addresses.
AutoFocus - Answer-Speeds up an organization's ability to analyze threats and respond
to cyberattacks.
PANOS - Answer-Software that runs Palo Alto Networks NGFW to provide complete
visibility and control of applications in use across all users, devices, and locations all the
time.
Panorama - Answer-Enables centralized control, log collection, and policy workflow
automation across all NGFWs
