Study Notes
Network Security and OSPF Concepts
- Cost in OSPF is calculated as interface bandwidth divided by reference bandwidth.
- Spyware collects user information without consent and sends it to other parties.
- In OSPF, DBD packets are exchanged during the Exchange state.
- OSPF can be configured directly on the interface using the
ip ospfcommand. - At the FULL state in OSPF, routers possess converged link-state databases.
- The SPF algorithm processes routers during the FULL state in OSPF.
- A VPN creates secure tunnels for corporate site connectivity and remote user access.
- The wildcard mask for a subnet of /25 is 0.0.0.128.
- Debuggers are used for reverse engineering binary files; both by black hats and white hats.
- The Link-State Database contains topology information in OSPF.
- Assets include anything of value to an organization, such as data and resources.
- The Adjacency Database is associated with the OSPF neighbor table.
- A vulnerability signifies a weakness in a system that can be exploited.
- In point-to-point networks, routers determine who will initiate DBD packet exchanges during the ExStart state.
- The Adjacency Database is used to create the OSPF neighbor table.
- Type 1 OSPF packets manage adjacency with other routers.
- Dijkstra's algorithm computes the cost for each route in OSPF.
- Type 3 OSPF packets offer an abbreviated list of the sending router's LSDB.
- In multiaccess networks, election of a Designated Router (DR) occurs during the Exchange state.
- The DR in OSPF utilizes the multicast IPv4 address 224.0.0.5 for communication with all OSPF routers.
- When the OSPF hello timer is set to 40 seconds, the default dead interval is 4 times that period—240 seconds.
- Address spoofing falls under social engineering attacks.
- With a hello timer of 15 seconds, the dead interval defaults to 60 seconds.
- The routing table is linked to the Link-State Database within OSPF.
- An IPS actively monitors traffic for malware signatures and can halt threats upon detection.
- The DOWN state indicates that no Hello packets have been received during OSPF operations.
