De-primeterization - Answer Access to information systems may be made from devices
outside of the enterprise network.
Example: Smart phone used to access an IOT device transmitting telemetry data.
Regulatory or industry compliance in regards to the network segmentation forces what
separation - Answer Business Units and Processes
What is DID? - Answer Defense in Depth! Having multiple layers of security on a network so
some layer catches on to the attack
What is the OSI model? - Answer - Physical layer 1
- Data link layer 2
- Network Layer 3
- Transport Layer 4
- Session Layer 5
- Presentation Layer 6
- Application Layer 7
What is UTM? - Answer Unified threat management- offers firewall functionality and many
additional security functions; it is deployed as a single security appliance or software solution
DOESNOT OFFER DiD(requirement for enterprise) This can still work for small enterprises
What are the security features of UTM? - Answer -Network Firewall
-IDS
-IPS
-Deep packet inspection(DPI)
-Anti Virus capability
-Web application fire wall(WAF)
-Web proxy and content filtering
-Spam filtering
,-SIEM
What are Adv/DisAdv to UTM? - Answer +Reduction in management actions
+Reduced foot print in the data center
+Less cost
-Risk of SPOF
-Negative Performance due to workload
What is the most commonly adopted ids/ips? - Answer NIPS (especially for enterprise)
In general ips/ids help stop attackers while they are gathering information
What are the two main techniques that are routinely used to detect incidents? - Answer
Signature based detection: compares know signatures against network events.(events written
by vendor or operator)
Ex:Rule set in place to restrict root login OR
Email with the subject password reset with passrgen.exe attached.
Anomaly based detection: compares what is considered normal with observed events to
identify significant deviations.(great for unknown threats)
Ex: the smtp server normal contributes to 23% of traffic and it bumps up to 70
What is the difference between NIPS AND NIDS? - Answer NIPS: sits behind a firewall and
traffic needs to be forwarded on to the network CAN BLOCK: unwanted traffic and Payloads
What does in-line mean? - Answer It means the device is directly behind the firewall and
traffic needs to be forwarded
Does a network IDS need to be inline? - Answer No it can monitor traffic but will need to use
port mirroring or spanning on the network switch to be effective
What is a wireless IPS? - Answer Designed to detect the use of rogue or misconfigured
wireless devices. Can build up a database of known trusted hosts on the network and can also
be used to prevent DoS attacks
, Rogue meaning a device that can spoof a MAC address of a trusted device.
An effective WIPS should mitigate what type of threats? - Answer -Ad hoc networks: P2P
connections
-Rogue access points: Attackers that bypass perimeter security
-Evil-Twin APs: Users that's may connect to a lookalike network and be vulnerable to sniffing
-Misconfigured APs: configuration errors
-Client misassociation
-MITM attack
-MAC Spoofing
-DoS attack
What is HAIPE-IS? - Answer High Assurance Internet Protocol Encryptor Interoperability
Specification
REQUIRES: inline network encryption (INE)
What is an example of INE? - Answer Tactical Local Area Network Encryptor (TACLANE)
Military grade meets NSAs security requirements
What is NAC? - Answer Network Access Control (NAC) enforces a strong secure posture for
devices
MAJOR CHALLENGE: BYOD
GOAL: make sure access is controlled, devices have anti virus, and a firewall
EXPECTATION: users connect via VLAN using a captive portal ( think segmentation)
What is a SIEM? - Answer Allows an organization to centralize security management events.
Provides correlation and normalization for context and alerting and also provides reporting and
alerts based on real data inputs.
